The owner complained about the purchase of Tesla < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E6%B1%BD%E8%BD%A6 "> car < / a > exists" < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E5%88%B9%E8%BD%A6%E5%A4%B1%E7%81%B5 "> brake failure < / a >" problem < p > in recent days, the incident has been constantly fermenting, and the central media and regulatory authorities have voiced their voices. Tesla's attitude has changed from "intransigence" at the beginning to apology, and expressed its willingness to provide vehicle data. On the evening of April 22, Tesla provided the original data of the vehicle half an hour before the incident to the owners < p > this is a positive beginning of Tesla's "brake failure" incident towards the goal of restoring the truth and solving the problem. However, behind the data provided by Tesla, there are still many questions to be solved, such as, what does the data say? With the data, can we restore the truth of the incident? Which organizations can do a comprehensive analysis of the data

Question 1: what does the vehicle data before the incident indicate < p > < p > on the evening of April 22, Tesla provided the Beijing News shell finance reporter with one minute data of the previously suspected "brake failure" accident. Tesla said that because the data belongs to the owner's privacy, it is not convenient for Tesla to disclose more data unless the owner releases it by himself < p > according to Tesla, in the 30 minutes before the accident, the vehicle had more than 40 brake pedal applications According to Tesla, < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E9%A9%BE%E9%A9%B6%E5%91%98 "> when the driver pressed the brake pedal for the last time, the vehicle speed was 118.5km/h. Within 2.7 seconds after the driver stepped on the brake pedal, the maximum pressure of the brake master cylinder was only 45.9 bar. After that, the driver stepped on the brake pedal more, and the pressure of the brake master cylinder reached 92.7 bar. Then, the front collision warning and automatic emergency braking function started (the maximum pressure of the brake master cylinder reached 140.7 bar) and played a role, reducing the impact amplitude. 1.8 seconds after the action of ABS, the maximum pressure of the brake master cylinder reached 140.7 bar, The system records the occurrence of the collision. After the driver stepped on the brake pedal, the speed continued to decrease. Before the collision, the speed decreased to 48.5 km / h < p > Tesla said that when the vehicle was driving at a higher speed, the driver began to press the brake pedal with less force. After that, the automatic emergency braking function started and played a role, which improved the braking force and reduced the impact of the collision. The braking system normally intervened and reduced the speed < p > according to the rights owners, after the accident, they found Tesla and asked for vehicle data, which was not satisfied. With the attention of regulatory authorities and public opinion, Tesla said it was willing to provide the original data of the vehicle to the owners before the incident On the evening of April 21, Tesla issued a statement saying that it was willing to provide the original vehicle data half an hour before the incident. On the afternoon of April 22, Tesla responded to the shell financial reporter of Beijing News, saying that the company had actively contacted Zhengzhou Zhengdong Market Supervision Bureau and reported the progress. On the same day, it would provide the original vehicle data half an hour before the accident to Anyang owners < p > Tesla said that the identification and testing contents of the vehicle are mainly traffic accident cause analysis and brake quality identification. The appraisal materials include the vehicle itself, the accident confirmation, relevant audio-visual materials, etc. The detection of automobile braking system will be carried out by the combination of real vehicle survey and vehicle data, and the domestic qualified appraisal institutions have the ability and license to identify and detect the above contents < p > Ms. Weiquan's cousin said publicly that she was worried that the "brake failure" vehicle had been repaired by Tesla, and that Tesla would automatically clean up the previous fault information after the system was restarted, so that the third-party testing agency could not detect the real results < p > in this regard, Tesla said that vehicle data is the vehicle gateway to read the signals of various components in the vehicle and store them in encrypted form. The stored data is recorded by encryption technology, which can't be read, modified or deleted directly. In case of product quality disputes, Tesla will provide real and complete vehicle data according to law

Second question: who will be the third party to test the Tesla accident vehicle < p > < p > on the evening of April 21, Tesla announced the progress of handling the rights safeguarding incident on its microblog. At the same time, it also urged Zhengzhou Municipal Supervision Bureau to appoint an authoritative and qualified third-party testing and Identification Organization to carry out the testing and identification work and restore the truth as soon as possible. "No matter what the testing results are, we will accept them." According to Ms. Zhang's previous introduction, on February 21, Ms. Zhang's father's Tesla had a car accident due to brake failure, so her parents were hospitalized. Ms. Zhang then asked for a refund, but Tesla offered to let the insurance company repair the car and sell it < p > Ms. Zhang's cousin previously publicly said that Tesla had provided a 5.09 second background driving data, which showed that the Tesla's speed reached 118.5km/h at the time of the accident, while Ms. Zhang's cousin said that the accident happened at the rush hour and the speed limit of national highway 341 was 80km / h, so she did not agree with the above data provided by Tesla < p > because of this, Ms. Zhang also refused to carry out the third-party test before < p > the response of the person in charge of the press and Publicity Department of Zhengzhou market supervision bureau also confirms this point. It is reported that the market supervision bureau of Zhengdong New Area organized the complainants and Tesla automobile sales service (Zhengzhou) Co., Ltd. to mediate on March 15, 18 and 24 respectively. The complainants did not agree with the third party's technical appraisal and asked for "complete driving data half an hour before the accident". Tesla automobile sales service (Zhengzhou) Co., Ltd. refused to provide relevant data for fear that the data would be used by the parties to hype and publicize and cause adverse effects. The two sides failed to reach an agreement because of their great differences On April 22, Zhengzhou Municipal Bureau of supervision and Zhengzhou Zhengdong New District Municipal Bureau of supervision both told reporters that, as a mediation organ, the Municipal Bureau of supervision will not appoint an appraisal institution, which is mainly discussed between the complainants and Tesla, and the third party with testing qualificationThree party testing institutions are in the optional range, not limited to Zhengzhou, as long as the two sides negotiate well, "all over the country."

Third question: can identification and testing find out the truth of the incident < p > < p > Cui Dongshu, Secretary General of the National Joint Conference on passenger car market information, told reporters that at present, institutions on the market basically only detect mature and long-term developed technologies. Tesla's software and system are relatively new for some institutions, so it is difficult for institutions to detect them. Even if they can detect them, the process is relatively long < p > on April 22, the reporter of Beijing News shell finance randomly called a number of automobile testing institutions, and the other party said that they could test the hardware of the vehicle, but if there were problems in the software or system, the existing technology of the institution could not guarantee the detection < p > "Tesla has its own brand protection and set restrictions on private data, which can't be read by the outside world." The service personnel of one car one inspection told reporters that it is difficult to detect whether Tesla has brake failure < p > the other party explained that if the vehicle brake fails, it is generally not a hardware problem, but mostly a software problem, which can be identified by the OBD computer detection of the whole vehicle and read the engine and transmission data, but Tesla gets the data through its internal sensors and monitoring equipment and sends it back to the headquarters, which can not be done by external technical means, "It's not even possible to read it." < p > the other party further said that if Tesla is willing to provide historical data, such as stepping on the brake but not slowing down on the highway, and the brake light has been on but not slowing down significantly, these data may prove that Tesla may have brake failure, but this can only be provided by the brand side < p > "in this case, it is recommended to find a manufacturer." The service personnel of pony testing group told reporters that if the Commission certificate of automobile 4S shop is issued, automobile testing can be carried out in the group, but the group can only test hardware problems. If it is a system problem, the manufacturer needs to issue data and test report, and the group cannot test this aspect < p > "we can't detect it either, because we need to use Tesla's special computer." The service staff of the car inspector also told the reporter that the company has done vehicle detection for Tesla before, but mainly in terms of hardware. In terms of software, the company uses the OBD computer detection for the whole car. Because Tesla has many functions, it can't use the OBD detection. "Tesla's battery and brake are controlled by software, so we can't test them." < p > the service staff of the car inspector told the reporter that the software detection is not completely related to the background data, and the reason why Tesla's software cannot be detected is that the detection organization does not have the equipment. The service personnel of the group also said that if they get the background data, they can directly let the manufacturers analyze it

Fourth question: what's the situation of the car owners < p > < p > on April 19, at the Tesla booth at the Shanghai auto show, a woman wearing a shirt with "brake failure" stood on the roof of the car and yelled "Tesla brake failure", which caused a crowd to watch. The woman was later taken away by the staff < p > the next day, Shanghai police reported that at about 11:24 on April 19, 2021, Shanghai Qingpu Public Security Bureau received a report that someone was making trouble in a booth of Shanghai auto show. Police rushed to the scene immediately. After investigation, Zhang (female, 32 years old) and Li (female, 31 years old) went to the auto show on the same day to express their dissatisfaction because they had a consumption dispute with the brand company. Meanwhile, the two people in the booth area through wanton noise and other means, once caused chaos on the scene. Zhang also ignored the staff's dissuasion and forced to climb on the roof of an exhibition car, causing damage to the vehicle to a certain extent. At present, Zhang was sentenced to administrative detention for five days for disturbing public order, and Li was given an administrative warning for disturbing public order < p > Beijing News shell financial reporter learned from the relatives of the female car owner that she is still in custody and will be released the day after tomorrow (April 24) In the afternoon of April 22, when Tesla disclosed the latest progress, it said that it would provide the original data of the vehicle half an hour before the incident to the vehicle owner on the same day. In view of the fact that the female vehicle owner is currently in custody, it can provide the electronic version or mail it to the husband of the female vehicle owner

Five questions: what is the latest position of the regulatory authorities < / P > < p > with the fermentation of Tesla owners' rights protection incident, the official voice also appeared On April 20, Xinhua News Agency commented that as a "Star" brand in the automotive industry, Tesla's self requirements for quality and its commitment to users need to match market expectations in order to gain more trust and favor from consumers. For enterprises, providing high-quality products and services is the right way < p > subsequently, the Central Commission for Discipline Inspection and the State Supervision Commission commented on the Tesla car owner rights incident, saying that enterprises must abide by the law, respect consumers and respect the market. An Jian, head of the central political and Legal Commission, also issued an article saying that Tesla must face the torture of Chinese customers. What is its responsibility? What is the responsibility < p > on the night of April 21, the State Administration of Market Supervision issued a document saying that the rights protection of Tesla car owners at the Shanghai auto show has aroused widespread concern, and the State Administration of market supervision has attached great importance to it, and has instructed the market supervision and administration departments of Henan Province, Shanghai city and other places to safeguard the legitimate rights and interests of consumers in accordance with the law. At the same time, it emphasizes that enterprises should earnestly fulfill the main responsibility of quality and safety, and provide consumers with high-quality and safe products and services < p > the China Consumer Association also issued an article saying that the primary premise of business operation is to respect consumers. Enterprises should implement product quality responsibility in accordance with the law and take effective measures to protect the safety rights and interests of consumers. Enterprises have the obligation to provide evidence to prove product safety, take measures to improve the quality of products and services, and show sincerity to solve the consumer demands involved Before that, the market supervision bureau of Zhengdong New Area ordered Tesla automobile sales service (Zhengzhou) Co., Ltd. to unconditionally provide Ms. Zhang, a rights car, with complete driving data half an hour before the accident < p > after a series of voices from regulation and public opinion, Tesla began to go from "uncompromising" to apologizing, and then to providing vehicle data to restore the truth < p > Zhao Zexiao, shell finance editor of Beijing News, told Xue Jingning < / P > < p > <-- EndFragment-->
