Shanghai bill exchange opened today, and the bill market has entered a new stage.

　　Cctv newsThe Shanghai Bills Exchange, led by the head office of the People’s Bank of China, officially opened this morning.

　　Zhou Xiaochuan, Governor of the People’s Bank of China, said that the formal establishment of the Shanghai Bill Exchange is an important measure to deepen financial reform and development in China. In recent years, the rapid development of China’s bill market has played an important role in broadening the financing channels of enterprises and improving the multi-level financial market system. As a national unified bill trading platform with multi-functions of bill trading, registration and custody, clearing and settlement, and information service, Shanghai Bill Exchange will greatly improve the transparency and trading efficiency of the bill market, stimulate market vitality, and better guard against bill business risks; It is also helpful to improve the central bank’s financial regulation, optimize the transmission mechanism of monetary policy, and enhance the ability of financial services to the real economy.

　　The so-called negotiable instrument, according to the definition of China’s "Negotiable Instrument Law", refers to the securities with the purpose of paying money. Generally, it refers to bank drafts and commercial drafts, checks and cashier’s checks. Bills can be used for payment, mortgage and loan, and also have many functions such as financing, circulation and settlement. It is a common tool in modern finance.

　　According to insiders, China’s bill market is basically a spontaneous market at present, and various transaction barriers and information asymmetry have reduced the resource utilization efficiency of the bill market to a certain extent and increased the financing cost of the real economy, especially small and medium-sized enterprises. The establishment of the bill exchange will break the current bill market structure, form an intensive market organization form with legal persons as the main participants, electronic custody of paper bills and centralized and transparent information, help to break through the restrictions of geography and time on transactions, enable market participants to obtain more comprehensive and true market information, establish a nationwide, highly centralized and unified market form, improve the owners’ willingness to trade and speed of circulation, and further strengthen the supporting role of bill acceptance and discount to the real economy.

　　At the same time, the establishment of the bill exchange is helpful to improve the risk management level of the whole bill market. Bill business involves many risks, such as compliance risk, market risk, operational risk, moral hazard, etc., and there are many characteristics such as large amount of cases and hidden modus operandi. In recent years, a number of bills-related cases broke out in Agricultural Bank of China, China CITIC Bank and bank of tianjin, and some cases involved billions of yuan, which brought great risks to the market. The establishment of the bill exchange will help the central bank to standardize the market behavior, and by issuing and solidifying the bill supervision regulations and risk dynamics, it will help to enhance the understanding and understanding of the bill rules and regulations, risk prevention and control, and compliance operation of market participants, and improve the compliance of market participants’ behavior.

　　In addition, the settlement of Shanghai Bill Exchange in Shanghai has a far-reaching impact on the construction of Shanghai International Financial Center and Pilot Free Trade Zone. It is conducive to enriching the infrastructure of the financial market and further improving the market system and functions of Shanghai International Financial Center; Further enhance the global influence of Shanghai International Financial Center.

　　After its opening today, Industrial and Commercial Bank of China successfully completed a 1 million-yuan commercial bill reposting and cash selling business on the Shanghai Bill Exchange, which is also the first bill reposting and cash selling transaction after the opening of the Shanghai Bill Exchange.

Rooney Mara： The Successful Evolution History from the Rich Second Generation to the Little White Rabbit

　 　 Special feature of 1905 film network　Because The Girl with the Dragon Tattoo first met Rooney Mara, and because many fans of Carol fell in love with her.

　 　 Obviously, Rooney Mara didn’t become famous overnight. She just played some bit part. She has never played a leading role in Urban Legend: Bloody Mary, starring her sister kate mara, or in Dream Boys, Law and Order and other works.

　 　 Even unlike kate mara, the debut sister of the child star, Rooney Mara was not interested in performing since he was a child, and even some were afraid of performing. But the charm of art gradually took root and sprouted in the girl’s heart, and her infinite performance potential was slowly stimulated.

　 　 In fact, Rooney Mara doesn’t have to go into acting. Because she can be said to be a veritable rich second generation.

　 　 Her name represents the two giants in American football, and her father represents the Mara family. Rooney Mara’s great grandfather was the founder of the American football team, the New York Giants. When talking about the New York Giants, netizens who like football should not be unfamiliar. It is one of the old NFL teams and has won many NFL championships.


　 　 On the other side is the Rooney family represented by Rooney Mara’s mother, which is also a big-name family in rugby. Her great-grandfather founded another football giant, Pittsburgh pittsburgh steelers.


　 　 To sum up, Rooney Mara’s name represents a strong alliance between the two football giants. This is the real rich second generation.

　 　 Rooney Mara, who thought she would inherit the family business and continue to be a princess, gradually evolved into a "white rabbit" because of The Girl with the Dragon Tattoo.


　 　 Director david fincher has an eye for pearls and decided to make Rooney Mara the heroine of this film. Because of this film, the White Rabbit won the Golden Globe Award and the Oscar nomination for best actress.

　 　 In order to play a good role in the play, she did not hesitate to get holes in her body and face, cut a punk hairstyle, bleach her eyebrows and adapt to life in Stockholm.

　 　 It is also because of her efforts that Lisbeth Salander has become the central blood of the film without controversy. Because of this film, we can see a different Rooney Mara.

　 　 She can be crazy and play a marginal figure, but she can show her inner soft and gentle side to the fullest. It is hard for the audience to imagine why this girl is so different, but she will slowly accept and understand her from the bottom of her heart.

　 　 We often say "Dedicate ourselves to art". Rooney Mara’s subversive modeling in The Girl with the Dragon Tattoo has released herself and made many female fans exclaim that they want to marry.


　 　 If "The Girl with the Dragon Tattoo" has released Rooney Mara’s great performance potential, then "Carol" has further broadened her career and given her unlimited possibilities for interpretation.

　 　 She succeeded in bringing to life a girl who met her beloved and was ignorant of spring. Even for a long time, many fans thought that she and Cate Blanchett were the most beautiful twins.

　 　 When Trish, played by Rooney Mara, saw Carol, played by Cate Blanchett, in the store, and her eyes stared closely, she knew that her life might be inextricably linked with this blonde lady.

　 　 She made up her mind to walk away with Carol, and she completely understood what love was. This time, Rooney Mara doesn’t need much change in appearance, just a look and a detailed description of an action in the movie. You can show everything to perfection.

　 　 She longs for love with Carol, but she also cares about her hands and feet, but when her lover really stands in front of her, she bravely expresses her true nature.

　 　 She is really a little white rabbit. In Carol, when she sees Blanchett, she will panic, and her heart will jump like kicking a white rabbit. But in front of your lover, you can also show your purest feelings naturally.

　 　 Whether it’s the other puffed-up but warm Sahlander in The Girl with the Dragon Tattoo, or a role created later. She can always substitute herself into the role well, so that fans can fall in love with the role and be more infatuated with this beautiful girl without losing her acting skills.

　 　 Yesterday, Una, starring Rooney Mara and Ben Mendelsohn, was finally announced to be released soon.

　 　 This time, the white rabbit is about to take on a new look, reinterpreting a story of lover’s reunion after fifteen years.


　 　 Una (Rooney Mara) shows up uninvited in Ray’s office (Ben Mendelsohn), which makes him have to re-examine their relationship: Ray has started his new life, and Una is still looking for answers. The story revolves around their love and affection.

　 　 At present, the freshness of this film in rotten tomatoes is 88%. Expect the rabbit to bring a different performance.

　 　 Although Rooney Mara has a super high value and has naturally become the darling of the fashion circle, she conquered the vast number of fans by her superb acting skills.

　 　 She is a girl without a tattoo, a shy little white rabbit and an angel of fans.


China’s first ＂self-service intelligent security inspection channel＂ was opened at Guangzhou Baiyun Airport.

　　Jin Yang Network News reporter Tang Heng and correspondent Airport Xuan reported: Have you seen the automatic security check? On 25th, Baiyun Airport opened a "self-service intelligent channel" in Terminal 1 security area B, which is the first security channel in China to integrate all self-service equipment into the same channel, which means that China civil aviation security is about to enter a new stage. Yangcheng Evening News reporter learned that the self-service intelligent security inspection channel will save more time for passengers. It is estimated that each intelligent channel will be able to check 20%-30% more passengers every day.

　　The passage is located in the No.9 passage in the security check area B of the departure hall on the third floor of the T1 terminal of Baiyun Airport. It is self-help and intelligent all the time, and the passage is also equipped with a "re-inspection robot". Passengers can successfully pass through two self-service gates with their boarding pass (including electronic boarding pass) and ID card. The system automatically compares the passenger’s identity information with the ticket information, which takes less than 10 seconds to add up, saving half the time compared with manual inspection. After passing through the gate, passengers still need to put their belongings in the basket for X-ray inspection, and sensitive items such as computers, iPad and charging treasures need to be taken out separately. Subsequently, passengers can pass through the millimeter-wave security door, and the instrument will automatically scan to determine whether there are foreign objects all over the passenger’s body. If not, passengers can pass quickly; If yes, the approximate location of the item will be marked on the instrument screen, and the security inspector will conduct targeted re-inspection.

　　If there are suspected illegal items in the carry-on baggage, they will be automatically diverted to the unpacking desk by the system, and the security inspector will open the bag for inspection, and then re-examine the relevant items after taking them out.

　　How to prevent fire in shopping malls?

　　1. It is forbidden to bring inflammable and explosive dangerous goods into public places; It is strictly forbidden to smoke and use naked flames in places where there is a danger of fire and explosion.

　　2. It is forbidden to occupy the evacuation passage and exit when erecting the booth, and the electrical wiring should be connected by professional electricians. It is forbidden to use high-power electrical equipment illegally.

　　3.
Shopping malls and markets are crowded with people, so it is necessary to strengthen fire inspection, ensure the safety exits and evacuation passages are unblocked, train employees to master the knowledge of fire fighting and evacuation at the beginning, and ensure the timely disposal and evacuation of people in case of fire.

　　4. At the end of the business, employees should be arranged to conduct a post fire inspection, and special personnel should be arranged to patrol at night.

Jerry Yan joined Jay Chou’s six brokers within three years (Figure)


　　Jerry Yan


　　Last night, Jewell Company, which is owned by Jay Chou and participated in the investment, announced that it will help to handle all brokerage affairs in Jerry Yan from now on, and Jerry Yan’s agent will be Yang Junrong, who won the red Jay Chou.


　　"Heavenly King’s pet comes out": It hit it off with Jay Chou’s agent.


　　A few days ago, Jerry Yan arrived in Shanghai to shoot the idol drama Tears of Star Heart, which was jointly invested by CCTV and NHK. Yesterday, he spent the whole day filming interior scenes in his hotel, unwilling to accept any media interview about him becoming Jay Chou’s younger brother.


　　Yesterday, the reporter learned from Jewell Company that Jerry Yan and Jay Chou met in 2004. Both of them are members of the Taiwan Province Star Basketball Team, but they are just friends. The willingness of the two sides to cooperate began at the end of last year. After Jerry Yan set up his own business three years ago, he often hesitated in making decisions. The most impressive thing was the recent basketball fire, which finally decided to participate after repeated performances, but it became a supporting role for Show Lo.


　　In fact, Jerry Yan himself realized that his personality was very unfavorable to his development in the entertainment circle, so he decided to find a good agent to help him. At a party last year, Jerry Yan met Yang Junrong, Jay Chou’s agent. At that time, Yang Junrong touched him with a remark, that is, "The heavenly king is a pet", indicating that he respected Jay Chou and let him play according to Jay Chou’s personality. Because Jerry Yan’s difficulty is well-known in the circle, when he heard Yang Junrong’s remarks, he felt that the two sides had similar ideas and began to discuss the possibility of cooperation.


　　Six brokers in three years: the two parties have not officially signed the contract.


　　According to insiders, Yang Junrong was worried at first, because he also knew that Jerry Yan had changed six brokers in three years since he started his own business, so the two sides discussed the cooperation for a long time and reached a consensus only recently. However, the two sides have not signed a formal contract yet, and only a tacit agreement has been established at present. Insiders said that on the one hand, there should be a running-in process to prevent the two sides from breaking up in discord in the future; on the other hand, Jewel Company should also observe whether Jerry Yan can get along with Jay Chou. After all, Jewel has Jay Chou’s investment, and the company has been doing business around him. Now there is another big name, and the company can’t adapt at the moment.


　　It is understood that Jay Chou, who has always been a maverick, is willing to let the company sign Jerry Yan mainly because of his appeal in overseas markets such as Japan and South Korea. In Japan, Jerry Yan has the strongest appeal among Chinese stars. This time, NHK and CCTV co-produced Tears of a Star, and the Japanese first named Jerry Yan to play it. Therefore, Jay Chou hoped that Jerry Yan would help the company expand overseas markets, so when he knew that Yang Junrong intended to sign Jerry Yan, he readily agreed. After all, the joint efforts of the two could better consolidate the two major markets in China.

Real kung fu! Three Shandong guys made their own martial arts films and became popular. Netizen： It’s worse than the movie.

This article is reproduced from WeChat WeChat official account Qilu Evening News (ID:qiluwanbao002）。

What is the hottest kung fu on the short video platform recently? That must be the "Goro Bagua Stick".

Recently, Shandong guys Wang Qun, Sun Xingang and Zhang Jikun, who have been practicing martial arts since childhood, made their own martial arts films and uploaded them to the online platform through video recording. Unexpectedly, they unexpectedly became popular. The hottest video work "Five Lang Bagua Stick" has won more than 2.6 million praises from the public.

When recording a video, devote yourself to it. When broadcasting live, you are naughty and humorous.

"The Kung Fu Dream of the two uncles (Wu Kong)" is the Tik Tok uploaded by Wang Qun, Sun Xingang and Zhang Jikun, and their names are "Kung Fu" and "Humor".

What really made the three people popular was the 45 real kung fu videos uploaded by them, among which the most popular work was the "Goro Bagua Stick" with over 2.6 million praises. Judging from the video, their every move and every style is devoted. After the live broadcast, the three were naughty and humorous, and the interaction with fans was very casual.

Wang Qun told reporters that all three of them have been practicing martial arts since childhood, from Yantai, Weihai and Liaocheng, Shandong Province, and met in the Wushu Department of Chengdu Institute of Physical Education. At school, they were attracted by each other’s martial arts. After leaving the campus, Wang Qun runs a biotechnology company, Sun Xingang runs a teahouse, and Zhang Jikun has experience in martial arts instruction, and is knowledgeable in choreography and post-editing. Although they are engaged in different industries, they still come together with the same martial arts dream.

"You may not believe it when you say it. The idea of starting to shoot videos was talked about when we were sitting together for tea." Wang Qun said that when they talked about practicing martial arts that day, they didn’t have such advanced mobile phones and shooting equipment, and their previous training was not recorded. The three men proposed to realize their dream of a martial arts film by video recording, and at the same time, they could make a record of their martial arts, and the three men hit it off.

A month ago, they shot the first video and uploaded it to the short video platform, which gained more than 4,000 likes, which brought them confidence. "I didn’t expect so many people to like it. We three big boys got together to discuss whether to continue filming, and finally decided to continue filming." Wang Qun said.

Every time the video is shot, the three people play the action and plot on the spot. From left to right are Sun Xingang and Wang Qun. (Photo courtesy of the interviewee)

Every scene shooting is improvisation and plot.

Talking about the "Five Lang Eight Diagrams Stick" with more than 2.6 million praises, Wang Qun introduced that this video belongs to a relatively long shooting and production cycle. "It takes three or four days to shoot the video, plus two days of post-production, and it takes almost five or six days to do it well." Wang Qun said that the shooting cycle of some small clips is relatively short. For more than a month, they have basically maintained the frequency of updating every two days, and it takes about three or four days to shoot and post-produce.

In the uploaded videos, the real kung fu of the three people won everyone’s praise and recognition. In fact, these videos were not produced by a professional team. "Only the three of us, plus a photographer." Wang Qun said that since the explosion of fire on the Internet, many people have also asked them if there is a professional team operating.

In fact, every time the video is filmed, the three of them are improvising actions and paragraphs on the spot, and then adding the plot. Because many times three people need to appear in a martial arts film at the same time, they hired a professional photographer. If it is a relatively simple plot, Zhang Jikun, who has worked as a martial arts instructor, will shoot it himself and do the post-production.

Explain in detail the intelligent driver assistance system of Mercedes-Benz EQE, and how to realize each function.

It is obvious that Mercedes-Benz’s road to electrification is not smooth. In the process of "elephant turning around", although Mercedes-Benz launched a variety of new energy vehicles, it did not stir up any splash in the market, such as EQC, EQV and other models, which not only made the monthly sales volume bleak, but also accompanied by the huge suspicion of "changing oil to electricity".

Although it came late and got off to a bad start, the new energy market is the future direction of automobile development, and Mercedes-Benz certainly can’t let go of the "new energy track", so in order to get rid of the stereotype of "changing oil into electricity", increase the profit of pure electric vehicles and expand market share, Mercedes-Benz launched a new pure electric platform-EVA.

After that, Mercedes-Benz models were launched around the EVA platform, and EQS, EQS AMG, EQS SUV and Maybach EQS SUV were launched one after another.

However, the development of things did not succeed in Mercedes-Benz’s wish. Due to the high premium of new models and ungrounded conditions, EQS only achieved more than 200 vehicles in the domestic market in the first half of this year, accompanied by the dilemma of price diving, while other models were even more terrible.

Mercedes-benz EQS

Under the above background, Mercedes-Benz launched the domestic version of EQE, which is more affordable to the people, in an attempt to break this dilemma. However, competitors at this price are emerging one after another, such as BMW i4 and Audi A6 E-Tron, and new domestic forces have long been eyeing up. Therefore, it is not easy to regain a city in the new energy track if you want to rely on EQE. Among the three major parts of electric vehicles (driver assistance system related to three electric/intelligent/automatic driving), the performance of Mercedes-Benz EQE is very important.

At present, the automobile industry has entered the era of smart cars, and the most important embodiment of the intelligence of smart cars is the intelligent driving assistance system. At present, automatic driving cannot be realized, but they are all working in this direction. Mercedes-Benz EQE also regards its L2-level assisted driving as a big selling point in the module of "Perception of Technology".

(Information taken from official website)

So what is the strength of Mercedes-Benz EQE in today’s intelligent driving assistance among the three major electric vehicles? Is it worth looking forward to? In this paper, the intelligent driver assistance system of Mercedes-Benz EQE is analyzed in detail as far as possible through the exclusive arrangement of the intelligent driver assistance function, the configuration of major sensors, the topological structure of wiring harness and the realization paths of various functions.

First, the car profile and driver assistance functions are sorted out

At the beginning of this chapter, in order to make it easier for everyone to intuitively understand the current classification and progress of intelligent driving, and to understand the L2 intelligent driving assistance system of Mercedes-Benz EQE, the author combed out the following information on the basis of China’s Auto Driving Automation Classification (GB/T 40429-2021) which came into effect on March 1, 2022, combined with the actual car scenes used in the corresponding grades.

At present, autonomous driving technology is divided into six grades: L0-L5. Among them, L0 class can’t continuously perform the lateral or longitudinal motion control of vehicles in dynamic driving tasks, but it has the ability to detect and respond to some targets and events in dynamic driving tasks. In this stage, the automatic driving system can perceive the environment and provide information or temporarily intervene in vehicle control to assist the driver to drive the vehicle safely.

The L1-class driving automation system can continuously perform the lateral or longitudinal motion control of vehicles in dynamic driving tasks under its design and operation conditions, and has the ability to detect and respond to some targets and events that are suitable for the lateral or longitudinal motion control of vehicles. The driver and the automatic driving system can perform the driving tasks of vehicles at the same time. At this time, the driver is more like a security officer and mainly supervises the driving behavior of the automatic driving system.

L2 level has the functions of ACC, LCC and other level 1 autopilot systems, and it also has the ability to control lateral and vertical motions at the same time. In the autopilot function of L0-L2 level, the driver has the highest control authority and can intervene at any time to immediately release the control of the autopilot system, which is also the level that can be achieved at present.

L3 level means that the system continuously performs all dynamic driving tasks under its design operating conditions, L4 level means that the system continuously performs all dynamic driving tasks and automatically executes the minimum risk strategy under its design operating conditions, and L5 level means that the system continuously performs all dynamic driving tasks and automatically executes the minimum risk strategy under any driving conditions.

With the above basic information, it will be more convenient to understand the intelligent driver assistance system of Mercedes-Benz EQE.

At present, the domestic version of Mercedes-Benz EQE has a total of three vehicle configurations. The price of EQE 350 Pioneer Edition is 528,000 yuan, the price of EQE 350 Deluxe Edition is 546,000 yuan, and the price of EQE 350 Pre-model Special Edition is 585,000 yuan. It is positioned as a medium and large pure electric vehicle with a cruising range of 717km-752km. According to official data, it provides L2 intelligent driving assistance system.

Turning back to the driver’s assistance function of Mercedes-Benz EQE, the author translated and sorted out various intelligent driver’s assistance functions of Mercedes-Benz EQE by reading the information of Mercedes-Benz official website.

(Translated according to Mercedes-Benz official website data)

For car companies, all intelligent functions are usually divided into two categories: driving and parking. First, because the speed of vehicles is different when driving and parking, the research objects, the application of sensors and various algorithms including decision-making algorithms are also different at the technical level. Second, the functional configuration of intelligent driving is the research object, and the corresponding results are more convenient to be matched on different models in a menu manner.

Mercedes-Benz also divides the intelligent driving assistance system into the above two categories, one is the auxiliary function during parking and the other is the auxiliary function during driving.

As can be seen from the information of Mercedes-Benz official website, the version of the driver assistance operating system comes standard with the classic version of the driver assistance component, while the middle-high version comes standard with the enhanced version of the driver assistance component. Functionally, the low version of the active safety early warning system does not have DOW door opening warning, but the middle-high version is standard. In addition, the road traffic signs in the low version are identified as optional, and the middle-high version is standard. In addition, the number of sensors in the low version is one less than the other two, and the difference lies in the number of cameras.

(According to the information of Mercedes-Benz official website)

However, there must be beautification packaging in the wording of the manufacturer, which may lead to our misunderstanding. In order to avoid this situation, the author will show you the essence through the phenomenon through several functions of Mercedes-Benz EQE.

(According to the data of Mercedes-Benz official website)

Second, the sensor composition of EQE intelligent driver assistance system

1. Number of sensors

Mercedes-Benz EQE provides 23 sensors related to the intelligent driving assistance system, including 1 long-distance millimeter-wave radar, 4 corner radars, 12 parking ultrasonic radars, 1 front binocular stereo multi-function camera, 4 360 parking cameras and 1 in-car viewing angle camera, etc., and is equipped with the enhanced version (P20) of the driving assistance module. The intelligent driving assistance function based on the intelligent navigation distance limiting function (ACCA) can achieve L2 automatic driving level.

In terms of sensor configuration, Mercedes-Benz EQE is far less than the current domestic models of the same level. The new HI version of Extreme Fox Alpha S is equipped with 34 sensors, the whole car of Tucki P7 is equipped with 31 autopilot sensors, and the whole car of Weilai ET7 is equipped with 33 sensors. The prices of these models are far less than those of Mercedes-Benz EQE. Therefore, in the era of smart cars, the cost performance of domestic models is still high, while the Mercedes-Benz brand still has a high premium.

In addition, Mercedes-Benz S-Class /EQS/EQE are all a scheme. There is a laser radar in the topology diagram of foreign vehicle controllers, but the domestic version of EQE has been replaced by a millimeter-wave radar instead of a laser radar, which is different from the foreign version.

One of the most obvious advantages of Mercedes-Benz EQE without laser radar is that it will save costs, because the imported Mercedes-Benz EQS, which is also based on EVA pure electric platform, is equipped with a laser radar. It is reasonable to say that EQE can support laser radar, whether it is overseas or domestic. On the other hand, the policies and regulations of different countries and even cities are different. For example, in North America, different states have different requirements for vehicle headlights. Therefore, in order to save trouble, the geometric multi-beam headlights provided by Mercedes-Benz in North America are also castrated, and the domestic version is the full version. However, the next plan of Mercedes-Benz EQE is to drive automatically at L3 level. In the future, if domestic policies allow, the domestic EQE laser radar will also be on the meeting.

2. Sensor layout

The specific layout of the sensor is shown in the following figure:

(Translated according to Mercedes-Benz official website data)

From the layout, one long-distance millimeter-wave radar is located in front of the vehicle, four corner radars are located on the left and right sides of the front and rear of the vehicle respectively, the positions of 12 ultrasonic radars are shown in the yellow icon in the figure, the front binocular stereo multifunctional camera is located on the roof, and four 360 parking cameras are located on two rearview mirrors and the rear half of the vehicle respectively.

Although the car has reached L2 level of intelligent driver assistance system, it is not worth showing off. L2 level is not high enough, and many cars with more than 100,000 can achieve L2.5 level.

3. Sensor brand, technical highlights and corresponding functions

The sensors carried by Mercedes-Benz EQE have been clearly analyzed. Let’s take a look at the advantages and disadvantages of various sensors:

The hardware of Mercedes-Benz EQE intelligent driving sensor basically comes from big factory suppliers.

In terms of millimeter-wave radar, there is generally a "1+4" method for the millimeter-wave radar equipped with intelligent driving in the industry. It is obvious that Mercedes-Benz EQE has also adopted this number with one long-range millimeter-wave radar arranged in front and four medium-short-range radars arranged at the side and rear of the car.

According to the network information, the millimeter-wave radar of China Net comes from the mainland, and the part numbers are A0009000536/A0009009638/A0009006444 respectively. The intelligent driving assistance function involved is the Distinctive Plus, which mainly participates in the professional version of the Distinctive Pro, the collision alarm and so on.

However, according to the data of foreign versions, there is another scheme for this millimeter-wave radar. The supplier is Bosch, and the part number is A0009052017/A0009055518/A0009051019. There are two possibilities, one is to mix them, and the other is to form a difference between the two.

The four corner radars come from Veoneer, a simple understanding of Veoneer, an automobile technology provider located in Stockholm, Sweden. Its products include radar, laser radar, vision system, advanced intelligent driving assistance, automatic driving software, night driving assistance system, active safety sensors, monocular and stereoscopic vision cameras, and it is worth mentioning that Mercedes-Benz is the first to realize L3 in the world.

The parts number of two corner radars on the outside of the front bumper is A0009051516/A0009059517, which cooperates with millimeter-wave radar to participate in the enhanced version of the automatic distance and speed adjustment system and advanced remote parking; The parts numbers of the two corner radars on the outside of the rear bumper are A0009003335/A0009003138 and A0009051416/A0009059417, which have two main functions. One is similar to the two corner radars on the outside of the front bumper, and cooperates with millimeter-wave radar to participate in the enhanced version of the intelligent navigation distance-limiting function system and advanced remote parking, and the other is to participate in the active blind spot auxiliary system.

The supplier of 12 ultrasonic radars is unknown for the time being. In terms of functions, 6 ultrasonic radars on the front bumper and 6 ultrasonic radars on the rear bumper are all active.

Looking at the visual level again, a binocular stereo multi-function camera on the roof of the domestic EQE adopts Veoneer fourth-generation stereo vision camera system, and the part number is A2239006128/A2239006830/A2239006830, which is composed of fully integrated hardware and sensing software. The camera has been upgraded from the third generation to the fourth generation, and the visual field has been expanded from 52 to 100, with improved accuracy and pixels. This camera uses convolutional neural network technology (CNN) to obtain the available space and detect small obstacles, and at the same time, it can accurately classify and locate the objects in front of the vehicle in combination with 3D stereo, which can be applied to most weather conditions. At the same time, thanks to the core algorithm of Mercedes-Benz, the binocular camera can detect the information of the target without classification, and the situation that obstacles cannot be identified can be well solved. At the same time, the stereo binocular can weaken the demand for lidar and reduce the cost.

It mainly participates in intelligent driving assistance functions such as active lane keeping assistance system, automatic high beam switching (IHC), automatic high beam switching, enhanced version (IHC+), traffic sign recognition, speed sign recognition, advanced head-up display (HUD), distance and speed automatic adjustment system enhanced version (DISTRONIC PLUS) and distance and speed automatic adjustment system professional version (DISTRONIC PRO).

The camera in the car comes from LG’s monocular camera, which is mainly involved in the attention assistance system and will give an early warning when necessary.

The supplier of the other four panoramic cameras for the middle net and exterior rearview mirror is Magna, which acts as a 360 camera and plays a great role in automatic parking.

Third, the brain of EQE intelligent driving system: chip

From the analysis of the sensors in the previous article, it can be seen that the number of sensors carried by Mercedes-Benz EQE is not large, so the requirements for computing power are far less than those of domestic new forces.

At present, the autopilot chip used by Mercedes-Benz EQE has not been disclosed, but according to industry speculation, the Mobileye EyeQ4 chip is used in a high probability.

EyeQ Ultra, the latest version of SoC of Mobileye.

Mobileye mainly provides intelligent assisted driving algorithm+chip solutions to meet the demand of L2-level autopilot. As of last year, about 70% of the world’s production cars were equipped with autopilot chips from Mobileye.

The Xavier 8 core chip of Mercedes-Benz NVIDIA that we often hear is not an intelligent driver assistance chip, but its main function is to support intelligent cockpit experience such as MBUX intelligent human-computer interaction system. In addition, this chip is really carried on the overseas version of EQE, and the domestic version of the chip is not clear.

At present, the computing power of Mercedes-Benz EQE’s self-driving chip is unknown. If it is really a Mobileye EyeQ4 chip, then the computing power is likely to be similar to that of Weilai ES8′ s Mobileye EyeQ4 chip, which is about 2.5TOPS.

However, it is worth mentioning that EQE will realize L3-level automatic driving next, and overseas AMG models of EQE have already confirmed that they will have L3-level assisted driving, so the following models should not adopt Mobileye again. As early as 2017, NVIDIA signed a cooperation agreement with Mercedes-Benz, which will provide smart cockpit chips and autopilot chips for Mercedes-Benz. Therefore, Mercedes-Benz EQE will adopt NVIDIA with greater computing power in the future.

Iv. Topology layout analysis of wire harness

If you want to know how to realize the intelligent driving assistance function of a car, you must know the wiring harness layout.

(Topology diagram of Mercedes EQE harness)

Automotive wiring harness is the network subject of automobile circuit, and there is no automobile circuit without wiring harness. In modern cars, there are many automotive wiring harness, and the electronic control system is closely related to the wiring harness.

Generally speaking, if the functions of microcomputer, sensor and actuator are compared with human body, it can be said that microcomputer is equivalent to human brain, sensor is equivalent to sensory organ, and actuator is equivalent to motor organ, then wiring harness is equivalent to nerve and blood vessel.

Previously, the four buses of automobiles were CAN, LIN, FlexRay and MOST. Generally speaking, CAN bus is the backbone, LIN is the deputy of CAN, FlexRay is the hope of the future, and MOST is responsible for cultural undertakings. However, with the increasing demand for intelligent driving in automobiles, high-speed data transmission is required for applications such as navigation system and parking distance control, so LVDS wiring harness is gradually emerging.

1. CAN bus layout of EQE

CAN is the abbreviation of ControllerArea Network, CAN), which is a multi-master bus between nodes for distributed control system. There is no master-slave distinction in data communication, and any node can initiate data to any other node (one or more), with the highest communication rate of 1Mbps. Taking CAN network as the main network can realize the intelligent control of the automobile, such as automatically locking the door at high speed and automatically opening the door when the airbag pops up. CAN is a Bus communication mode, which means that all nodes are connected to the same transmission medium, which means that the electrical signals in the transmission medium will affect all nodes.

From the vehicle controller topology of Mercedes-Benz EQE, we CAN see that Mercedes-Benz EQE still uses CAN as a means of controller networking. There are 20 groups of CAN buses in Mercedes-Benz EQE, which control many functions of EQE body, including steering wheel assembly/system, etc. In addition, it also plays a vital role in EQE’s intelligent driver assistance system.

2. LIN layout of EQE

LIN(Local Interconnect Network) bus is a supplement to other automobile multi-channel networks such as CAN. In general, LIN does not exist independently in automobiles, but is usually connected with other networks such as upper CAN network, which is suitable for applications that do not have too high requirements on network bandwidth, performance or fault-tolerant functions. For example, in Mercedes EQE, it is mainly used for window control, automatic back door, electric rearview mirror adjustment, seat heating and ventilation, etc., and the use of CAN bus for these functions will cause performance waste.

In Mercedes-Benz EQE, there are 40 groups of LIN buses connected to Ethernet, 1 group of LIN buses connected to FlexRay and 28 groups of LIN buses connected to CAN, some of which have the following functions, and are less related to the intelligent driver assistance system.

It is worth mentioning that Mercedes-Benz EQE is equipped with a new generation of MBUX intelligent human-computer interaction system, with a memory bandwidth of 46.4GB/s per second, which is at the leading level in the industry, so the smoothness of the car operating system is guaranteed to some extent.

3. FlexRay layout of EQE

FlexRay is the research and development achievement after CAN and LIN, which can effectively manage multiple safety and comfort functions. The maximum performance limit of CAN network is 1Mbps, and the maximum performance limit of LIN is 125Kbps, while the maximum data rate of FlexRay on two channels CAN reach 10Mbps, and the total data rate can reach 20 Mbps. Therefore, the network bandwidth of FlexRay may be as much as 20 times that of CAN when applied to vehicle networks.

FlexRay CAN run not only as a single channel system like CAN and LIN networks, but also as a dual channel system. Dual-channel systems can transmit data through redundant networks, which is also an important performance of highly reliable systems.

There are a set of FlexRay buses in Mercedes-Benz EQE, which play a vital role in the intelligent driving assistance of Mercedes-Benz EQE. The related FlexRay bus controllers are as follows:

4. LVDS of EQE

LVDS wiring harness is a bridge between the display screen and the communication motherboard, which plays the role of power supply and signal transmission, and the motherboard transmits the picture to the display screen, that is, the screen wire harness. Any running machine with a screen will inevitably have LVDS wires to transmit data.

There are many electromagnetic radiation sources in the automobile, so anti-interference ability is the most basic requirement of automobile electronic design. In addition, considering the low radiation advantage of LVDS transmission line itself, it hardly causes additional interference to other facilities of the system. LVDS transmission only needs simple resistance connection, which simplifies the circuit layout and the line connection is very simple (using twisted copper cable). LVDS is compatible with various bus topologies: point-to-point topology (one transmitter and one receiver); Multi-branch topology (one transmitter, multiple receivers); Multipoint topology (multiple transmitters, multiple receivers).

Mainly for the 360-degree panoramic image system of Mercedes-Benz EQE. The data transmission technology of Mercedes-Benz 360 image system has experienced two technical changes. Early models used LVDS low-voltage differential signal, while the latest models used HSVL high-speed video link. For example, for E-class cars, LVDS technology was used before 2021, and HSVL technology was adopted in 2021.

At present, there is no sign of LVDS wiring harness in EQE’s vehicle controller topology, but it is certain that Mercedes-Benz EQE adopts LVDS wiring harness.

5. Ethernet main bus of EQE

At present, the mainstream view in the mainstream industry thinks that vehicle Ethernet will become the development trend of intelligent networked automobile bus in the future, so this is also the mainstream direction of many automobile enterprises in research.

There are terminal nodes in the network, which simply means that there is only one Ethernet port on a node; And it is simply understood that there are multiple Ethernet ports on a node, and its main function is to forward information. Switch communication means that all terminal nodes can be connected together through switches, and all transmitted information needs to be forwarded by switches. In switched communication, only two ends of a network line are connected to two ports, and there is no bifurcation. So generally we don’t talk about Ethernet bus, but about Ethernet Network.

In Mercedes-Benz EQE, the Ethernet main bus is connected with 40 groups of LINs, and there is also a controller related to the intelligent driver assistance system:

Actual scene analysis, how does EQE intelligent driver assistance system work?

A car’s intelligent driving assistance system involves many levels, besides the sensor level, there are controller, electronic and electrical architecture level, algorithm and so on, which are the three main modules we often say: perception, decision-making and control. Generally speaking, it is similar to people’s eyes, brain and limbs.

The following will analyze how Mercedes-Benz EQE intelligent driver assistance system works from the practical application scenarios of various intelligent driver assistance functions.

1. PARKING (automatic parking)

On the aspect of automatic parking, major car companies are speeding up the mass production of automatic parking. From the perspective of China’s market layout, the concentration of car companies equipped with APA is high, and the top ten car companies account for 84.1% of the market share. The sales volume of Beijing Benz equipped with APA models is far ahead of other car companies.

At present, there are four automatic parking systems, semi-automatic parking (S-APA), automatic parking (F-APA, RPA), memory parking (HPP) and autonomous parking service (AVP).

The automatic parking function of Mercedes EQE is as follows:

(Translated according to Mercedes-Benz official website data)

Mercedes-Benz also explained EQE’s automatic parking system in detail.

(Translated according to Mercedes-Benz official website data)

According to the data of Mercedes-Benz official website, it can be found that the "parking package with 360 camera and remote parking functions" of Mercedes-Benz EQE supports active parking assistance, memory parking and remote parking assistance. In addition, there is a high-precision self-learning map, so the automatic parking system should be located at the highest SAE L4 level in the automatic parking class: Autonomous parking service (AVP).

According to the analysis of Mercedes-Benz EQE sensor, the configuration of the sensor conforms to the definition of autonomous parking service (AVP).

The automatic parking system includes sensing system, central control system, execution system and human-computer interaction system, which are connected by wiring harness. The fourth chapter above involves wiring harness.

From the design point of view, Mercedes-Benz’s parking system also adopts the integrated parking scheme of looking around and ultrasonic, and the whole car does not use lidar. If lidar is used, the problem of sensor perception limitation will be solved on a large scale.

From the perspective of the whole industry, at present, there are many L2 and L2+ automatic parking integration schemes with car-end transformation as the main technical scheme, and the L4 AVP is involved in Mercedes EQE, so it will also involve the construction of high-precision maps, and the map data needs to be updated regularly and in real time.

It is worth mentioning that the supplier of Mercedes-Benz’s high-precision map construction in overseas models is HERE, whose main function is to serve L3 autopilot. At present, Mercedes-Benz DRIVE PILOT autopilot has landed, and the high-precision map carried by EQE is also paving the way for L3 autopilot on EQE.

Mercedes-Benz DRIVE PILOTL3 Class Autopilot Landing

At present, the domestic version of EQE is equipped with NavInfo. As one of the earliest map vendors in China, NavInfo once became an "oligarch", and NavInfo has close ties with national car companies such as Tesla, Daimler, Ford, BMW, Guangzhou Automobile, Great Wall and Weilai.

According to NavInfo’s new public information, it won the order for the autopilot data management service platform for mass-produced vehicles from Daimler Greater China Investment Co., Ltd. last year, and will build and integrate Daimler’s domestic autopilot platform, and be responsible for the data management service of the platform from November 2021 to November 2024, and at the same time provide data processing services for the passenger cars mass-produced by Daimler Group in China from November 2021 to November 2024 through the platform, so the domestic version of EQE.

After the sensors mentioned above collect the vehicle position information and body state information, the sensing system converts them into digital signals, which provides the basis for the next path planning and decision-making.

In the process of signal transmission, it will be transmitted to the central control system through various routes in the previous chapter (Chapter 4). The specific transmission paths are as follows:

CAN bus –CAN S1 front radar controller area network, CAN S2 rear radar controller area network-controller 4 corner radars (B29/11: left front short-range radar (left front NBR), B29/12: right front short-range radar (right front NBR), B29/13: left rear short-range radar (left rear NBR), B29/14:

Ethernet main bus-controller N41/7: self-learning high-precision map (SHPK), N41/8: position determination.

Chassis FlexRay Bus-A40/11: Multifunctional Camera (MFK).

The information collected by the sensing system is processed and analyzed, and the current position of the vehicle, the position of the target and the surrounding environment are obtained. The central controller judges whether there are parking conditions according to these parameters, calculates the optimal path planning, generates corresponding control instructions, and sends the information such as steering torque and angle information needed in the parking process to the relevant actuators in the form of electrical signals through the vehicle network.

The implementation of Mercedes-Benz EQE is

The signal passes through the chassis FlexRay bus –N68: Electric Power Steering (ES)N68/4: Rear Axle Steering System (HAL)N80: Steering Column Module (Steering Column Tube Module (MRM)) and is finally reflected on the wheels.

The LVDS line is unclear.

2. DRIVING (driving)

In this respect, the functions owned by Mercedes-Benz EQE have been elaborated in the first chapter, and several representative functions are selected for analysis.

2, 1 Active Brake Assist (active brake assist)

Active braking assistance reacts to the actual situation. When there is a collision risk, Mercedes-Benz EQE gives a visual and audible warning, and when the driver does not respond, the system will assist braking.

The sensors involved in the perception level mainly include 1 millimeter wave radar and 12 ultrasonic radars.

Similar to PARKING, the signal is formed by the sensing system, and the transmission path is Ethernet main bus -A89: long-range radar (FBR). The transmission harness of ultrasonic radar is not clear for the time being, but it is clear that the signal must have been transmitted to the central control system.

Finally, at the actuator level, the vehicle will be braked, and the signal transmission path is:

Signal-Chassis FlexRay Bus –N68: Electric Power Steering (ES)N68/4: Rear Axle Steering System (HAL)N80: Steering Column Module (Steering Column Tube Module (MRM))- Brake

At the same time, the signal passes through CAN T：CPC harness to N12/2: SOGE to give an audible warning to the owner.

2, 2 Active Lane Keeping Assist system (active lane keeping assist)

During driving, when EQE deviates from the lane pressing line, the steering wheel will vibrate, and when there is an obstacle beside it, the system will sound an alarm, and at the same time, unilateral braking will intervene to assist the vehicle to return to the right position.

Perception system involves binocular camera on the roof, 4 cameras on the car body, millimeter wave radar, 4 angle radars and 12 ultrasonic radars.

Similar to PARKING, four corner mines are also required to collect information, and the information is transmitted by two wire harnesses: CAN S1: front radar controller area network and CAN S2: rear radar controller area network. This path also participates in active blind spot auxiliary system and intelligent navigation distance limiting function.

In addition, there is the signal of the binocular camera on the roof, and the chassis FlexRay bus-A40/11: Multifunctional Camera (MFK). This signal transmission path is also used in the intelligent navigation distance limiting function, speed sign recognition and traffic signal recognition function.

The information transmission path of millimeter-wave radar is similar to that of active braking assistance, so I won’t go into details, and it is also used for intelligent navigation distance limiting function.

At the execution level, the signal is also transmitted through the chassis FlexRay bus, and finally the vehicle sends out an alarm sound, and the system assists the vehicle to return to the right position.

There are many similarities in the transmission paths of active parking assist system, active braking system, active lane keeping assist system and intelligent navigation distance limiting function. The sensors, actuators and transmission paths involved in each function can also be clearly seen in the harness distribution in Chapter 4 above, and the general idea is similar to that of active braking assist system, active lane keeping assist system and automatic parking analyzed above.

The remaining auxiliary functions can also be analyzed according to the above ideas.

In addition, the actual experience of Mercedes-Benz EQE’s intelligent driver assistance system has been evaluated by German ADAC test before, as follows:

Mercedes-Benz EQE has excellent driving stability and insufficient steering accuracy, but fortunately, with the help of intelligent assisted driving, the model can easily keep driving in a straight line; In terms of braking, the brake pedal feels stiff and there is no clear pressure point. German ADAC test thinks that this is a point that Mercedes-Benz needs to improve, otherwise it will permanently interfere with EQE’s driving experience. In terms of active safety assistance system, Mercedes-Benz is in the leading position in the industry, which is also reflected in EQE models. Under the functions of emergency braking system, including collision and distance warning, it can ensure safety to a great extent; Pedestrian protection is equipped with an active hood, which will automatically rise in the event of collision, thus increasing the distance from hard engine parts. In addition, a predictive emergency braking assistant is standard, which can respond to pedestrians and cyclists.

On the whole, Mercedes-Benz EQE’s intelligent driving assistance has a good help in the actual driving process, but it should be noted that the models tested by ADAC are overseas versions, which are of reference to our domestic consumers, but not much.

VI. Summary

In the research and development of intelligent driving technology, Mercedes-Benz should be regarded as an early brand. As early as 30 years ago, based on the European "Eureka" research plan, it launched an intelligent transportation project called "Prometheus". From the end of 1990s to 2005, Mercedes-Benz introduced a distance control system named DISTRONIC and an upgraded version-Distronic Plus.

After 2015, Mercedes-Benz began to explore intelligent driving through travel services, and in 2018, it cooperated with doctors to launch the Robotaxi service of L4/L5 unmanned taxi in California.

In the last five years, there have been frequent actions. In July 2017, Mercedes-Benz invested in Momenta, a self-driving startup in China, and acquired Torc Robotics in April 2019, which significantly accelerated the intelligent strategy.

However, there is still a significant gap between this speed increase and the research and development, popularization and cost control of smart cars in China. Judging from the cost performance and quantity of its intelligent driving system hardware, the new force of making cars in China is basically the existence of this intelligent driving assistance system that can kill EQE, so from the comparison of peers, this system can’t support the price as high as 500,000 yuan.

Judging from the sensors carried by Mercedes-Benz EQE, it is imperative for Mercedes-Benz EQE to use L3 intelligent driver assistance system. If it can get on the road, then the new domestic forces will only increase, so the high premium of Mercedes-Benz will continue to exist to some extent.

Elon Musk： ＂Iron Man＂ in Silicon Valley

　　　
If you marvel at the myth of computer industry created by world-renowned entrepreneurs such as Bill Gates and Steve Jobs, then the next person will probably refresh your definition of myth. He is only 42 years old, but he has made brilliant achievements in the most popular and cutting-edge fields in the world today: he is the founder of the world’s largest online payment platform; He made the first commercially successful electric car; He is also the first private boss in the world to successfully launch a rocket. He is elon musk, the founder of Tesla, an electric car manufacturer, and Space X, a space exploration technology company.
　　Musk’s entrepreneurial experience is ups and downs and colorful. The famous Iron Man, which is widely circulated in the market, was adapted from him, and he himself made a guest appearance in the second film of the Iron Man series. Although the truth of this statement remains to be verified, just like this superhero, Musk’s wonderful life is full of dazzling high technology. Not only that, but his success in business operation is the envy of his peers. Some people think that he is a new legend after Jobs, while others say that he may be the next person to change the world.


　　Start with the internet


　　On June 28th, 1971, Musk was born in South Africa. My father is an engineer in South Africa and my mother is a Canadian. Musk learned software programming when he was 10 years old. Two years later, he successfully designed a game called "Blastar" and sold the software for $500, earning the first pot of gold in his life.
　　This child, who was called a "genius" by people around him, went to Canada at the age of 17, and his final dream was the United States, because he thought it was a place where "anything is possible". In 1992, after studying at Queen’s University for two years, Musk left Canada and transferred to the University of Pennsylvania, where he obtained a bachelor’s degree in economics and physics. When he graduated, Musk considered three areas that he most wanted to get involved in. In his view, these three areas will profoundly affect the future development of mankind, namely the Internet, clean energy and aviation. Now, it seems that these three ideals were all realized when he was under 40 years old.
　　In 1995, he went to Stanford University to study for a master’s degree in materials science and applied physics, but he dropped out of school after only two days. After that, he stepped into the internet field.
　　After dropping out of school, he and his brother jointly founded the Zip2 project, an online content publishing software developed for news organizations to help national online media cooperate with localized businesses. Soon, this creative project won the favor of several enterprises. In 1999, Compaq acquired Zip2 with $307 million in cash and $34 million in stock options. In the same year, Musk founded X.com, an online financial payment company. In 2001, X.com completed the acquisition of Confinity Company, and the new company was renamed PayPal. In October 2002, eBay bought PayPal for $1.5 billion, and Musk’s 11.7% stake in PayPal earned him $328 million. Today, PayPal has become the world’s largest online payment company, which is highly sought after by hundreds of millions of users around the world.
　　These two successful transactions made Musk famous and famous, and he became a billionaire and star entrepreneur. But just when people expected Musk to dig the next Internet gold mine, he chose another way. This time, he founded two miracle companies, Tesla and SpaceX.


　　"Upstream" Tesla


　　If Detroit is given a chance to start all over again, I believe that everything of Tesla will be what this bankrupt automobile city hopes to develop into: cooler, more environmentally friendly and more advanced.
　　Founded in 2003, Tesla Motors, headquartered in Palo Alto, California, is currently a star enterprise in the United States. The ModelS all-electric car produced by the company was listed as the best-selling luxury car in the United States, and was also rated as the safest car in the United States. Some media regard Tesla as "the apple of the automobile industry" and think that it represents a bright future for the development of the automobile industry.
　　The original Tesla company was not founded by Musk. At that time, Musk only invested $6.3 million in Tesla and became the chairman. Later, due to the unsatisfactory research and development, the two founders left, and Musk officially took over.
　　Musk said that his initial success rate was "less than 50%". But despite this, he still has confidence in Tesla. He believes that the traditional thinking about the electric vehicle market is one of the reasons why people have not discovered Tesla’s potential. He said that no one doubts that clean electricity is the future development direction, but the biggest uncertainty lies in the timetable of the historical process, that is, the time and speed of this transformation.
　　For this reason, in the entrepreneurial story of Tesla electric vehicles, Musk played more like the role that Jobs played in Apple: a preacher. He constantly explained the concept and spirit of Tesla to the media and the public, constantly convinced people that electric vehicles are the near future, and constantly responded to media attacks on Tesla. He also used the extensive influence of his circle of friends. In 2008, the first Tesla Roadster, the world’s first mass-produced electric roadster, was put on sale. Hollywood stars Tom Hanks, George Grugni and Schwarzenegger bought it one after another, and Silicon Valley tycoons such as Larry Page and sergey brin also helped. Musk mobilized all forces to push Tesla into the public’s sight.
　　Of course, in addition to strong publicity and public relations, the key factor to promote Tesla’s development is still technology. After solving the key technical problems such as high-capacity battery and high-performance motor, Roadster has been able to accelerate from 0 to 100 kilometers per hour in 3.6 seconds. At that time, it took 4.4 seconds for the Porsche 911 to reach the same speed. Looking back, Tesla’s success and stable battery system are the core of technology. Later, Tesla once transferred some key technologies of batteries and motors to help promote the electric vehicle revolution.
　　In 2012, the first ModelS rolled off the assembly line, and then ModelX came out. The more practical Model S is undoubtedly more successful than Roadster. In 2013, the global sales of Model S models are expected to reach about 21,000. On May 8, 2013, Tesla released its first-quarter financial report, achieving a net profit of $11.2 million. This is the first time that Tesla Motors has achieved quarterly profit since its listing in 2010. Since then, the company’s stock price has been like a runaway horse, rising from $55.7 to $90 in three trading days. At present, Tesla’s total market value exceeds 6 billion US dollars.
　　Tesla can gain a firm foothold and move forward steadily in the adverse waves that many electric vehicle companies have fallen, which is not unrelated to Musk’s precise positioning of Tesla. Musk said that he doesn’t think Tesla is competing with other electric vehicles for a small piece of the consumer market, but with fuel vehicles such as BMW or Lexus. Its real opponent is the entire traditional automobile industry system. At present, Tesla’s odds in this contest are hard to say, but what is certain is that Tesla is on the right track.


　　"Retire on Mars"


　　Among the three areas that Musk wants to get involved in most, aviation technology may be the one that fascinates him the most. "When other children look at the moon and sigh how far it is from the earth, Musk will say that its average distance from the earth is 384,400 kilometers," said his mother, May Musk, who described Musk as a child. When eBay threw an olive branch to PayPal, Musk realized that the time had finally come to realize his space dream. In June 2002, Musk founded SpaceX, a space exploration technology company, with his childhood dream.
　　SpaceX is mainly engaged in rocket business with reusable technology. In Musk’s vision, he hopes that the rocket can return to Earth after completing the space mission, thus reducing the cost of space flight. However, the wish is beautiful, but the reality is cruel. In 2008, after three failed launches, the Falcon 1 launch vehicle developed by SpaceX has exhausted the money that Musk earned from the sale of PayPal. That is, in the same year, Tesla encountered an unprecedented development bottleneck. The double crisis made Musk almost bankrupt.
　　But even so, Musk insisted on the fourth launch. He even said that "the fifth launch is also in preparation, and the plan to manufacture the sixth Falcon 1 has been approved." At that time, Musk had fallen into debt, and he knew that if he failed again, the consequences would be unimaginable. Therefore, it can be said that he made this decision with a burning heart.
　　As a result, a miracle appeared, and Falcon 1 successfully entered the preset orbit in the fourth launch test. The whole United States was shocked. People who scoffed at Musk’s idea of developing the cheapest transport rocket were surprised to find that the Falcon 1 launch vehicle used a partially reusable launch system, and the cost of launching once was only 6.7 million. At that time, the relatively cheap Pegasus rocket (a small launch vehicle launched from the air) cost 25 million dollars at a time. Musk’s vision became a reality.
　　Since then, SpaceX has won rocket commercial contracts from all over the world at a low price, and it has also won the recognition of the US government. It received a $1.6 billion order from NASA)16 and a $900 million deposit from other customers.
　　"Only four organizations in the world have mastered the technology of satellite launch and recovery, namely, the United States, Russian Federation, China and Musk," reporters said of this technology madman. Musk’s space dream continues, constantly creating one miracle after another. A few days ago, some media reported that Space X’s "Grasshopper Project" has successfully developed a cutting-edge technology that can make rockets take off safely and land vertically. Next, his goal is to reduce the launch cost to 1/10 of the commercial space launch market at that time, and he plans to develop super-giant rockets for interstellar migration in the future, because he firmly believes that the future survival hope of mankind depends on whether it can be moved to that red planet. Facing the eyes of doubt and ridicule, he said firmly, "I want to retire on Mars, which is a suitable place for retirement."


　　Creativity is infinite and enthusiasm is immortal.


　　Including the soaring stock price of Tesla electric vehicles, the outstanding performance of Musk’s companies this year has undoubtedly made Musk the most dazzling star in Silicon Valley. Because of this, he is called "the best entrepreneur in history", "the most inspirational entrepreneur" or "super idol". Looking back at the ups and downs of Musk’s entrepreneurial history, it is not difficult to find that high vision, bold vision and determination to put all your eggs in one basket are the greatest secrets of the legendary entrepreneur’s success.
　　According to Reuters, Musk always causes strong emotional fluctuations among people he works with. His colleagues either love him or hate him, and there is no centrist. However, even those who were fired by him, or those who called him heartless, have to admit that they admire his vision and willpower very much.
　　Darrell Silly, former director of market operation and sales of Tesla, said that Musk’s ability to remain calm in times of crisis is almost close to the non-human level. "His tolerance for risks is beyond imagination. When I was intolerable to the harsh environment, he was calm. "
　　It is with this enthusiasm that Musk has come all the way to today. As the British "Guardian" said, if someone puts forward such strange ideas as Martian immigration, the usual practice is to find an excuse to leave this madman’s company, or to politely smile and cater to this unrealistic fantasy of the space nerd, but if the object is Musk, it will have to be taken seriously.
　　Max Levchin, a friend who founded PayPal with Musk, said that Musk is like a "sword dancer in the dark". Every time he has a crazy idea, he always wants to make it at no cost. What’s terrible is that this wizard of science and technology entrepreneurship always seems to have a steady stream of new inspiration. He told the media that Tesla Motors will produce self-driving cars in the next three years; He talked about interstellar travel and immigration many times and said that he would shorten his trip to Mars to three months. Recently, he announced the "super high-speed rail" plan, which takes only 30 minutes to travel from Los Angeles to San Francisco … and it has stunned people again and again. However, despite the constant doubts from the outside world about Musk, we might as well look forward to it, given that he has so many successful records of turning whimsy into real applications.
