Tesla provided the data, then?Five questions about Tesla’s rights protection incident

0

Behind the data provided by Tesla, there are still many questions to be solved. For example, what do these data say? With data, can the truth of the incident be restored? Which institutions can do a comprehensive analysis and testing of the data?

At the Shanghai Auto Show three days ago, a female car owner from Anyang, Henan rushed to the roof, and Tesla rushed to the forefront of public opinion.The owner of the car complained of “brake failure” in the Tesla car he purchased.

In the past few days, the incident has continued to ferment, and the central media and regulatory agencies have voiced one after another. Tesla’s attitude has changed from “uncompromising” to an apology from the beginning, and expressed its willingness to provide vehicle data. On the evening of April 22, Tesla provided the original vehicle data half an hour before the incident to the car owners who defended their rights.

This is a positive beginning for Tesla’s “brake failure” incident to restore the truth and solve the problem. However, behind the data provided by Tesla, there are still many questions to be solved. For example, what do these data say? With data, can the truth of the incident be restored? Which institutions can do a comprehensive analysis and testing of the data?

One question:

What is the problem with the vehicle data before the incident?

On the evening of April 22, Tesla provided the Beijing News Shell Finance reporter with one-minute data on the previously questioned “brake failure” accident. Tesla said that because the data belongs to the privacy of the car owner, it is not convenient for Tesla to disclose more data unless the car owner publishes it himself.

According to Tesla’s description, in the 30 minutes before the accident, the vehicle had more than 40 records of depressing the brake pedal.

Tesla said that when the driver stepped on the brake pedal for the last time, the speed of the vehicle was 118.5 kilometers per hour. Within 2.7 seconds after the driver stepped on the brake pedal, the maximum brake master cylinder pressure was only 45.9 bar. After that, the driver increased the stepping on the brake pedal, and the brake master cylinder pressure reached 92.7 bar. The front collision warning and automatic emergency braking function were activated (the maximum brake master cylinder pressure reached 140.7bar) and played a role, reducing the amplitude of the collision. 1.8 seconds after the ABS was applied, the system recorded the occurrence of the collision. After the driver stepped on the brake pedal, the vehicle speed continued to decrease, and before the collision, the speed decreased to 48.5 kilometers per hour.

Tesla said that the vehicle was driving at a higher speed, and the driver began to depress the brake pedal lightly. After that, the automatic emergency braking function was activated and played a role, increasing the braking force and reducing the impact of the collision. The braking system is normally involved in the work and reduces the speed of the car.

According to the owners of rights defenders, after the accident, they found that Tesla asked for vehicle data without being satisfied. With the attention of the regulatory authorities and public opinion, Tesla expressed its willingness to provide the original data of the vehicle before the incident to the owner.

On the evening of April 21, Tesla issued a statement stating that it was willing to provide raw vehicle data half an hour before the incident. On the afternoon of April 22, Tesla responded to the Beijing News Shell Finance reporter that the company has actively contacted Zhengzhou Zhengdong Market Supervision Bureau and reported the progress. On the same day, it will provide the original vehicle data of the vehicle half an hour before the incident to the owners of Anyang.

Tesla said that the vehicle’s identification and testing content is mainly the analysis of the cause of the traffic accident and the identification of brake quality. The identification materials are the vehicle itself, the accident certificate, and related audio-visual materials. The inspection of the automobile brake system will be carried out by a combination of actual vehicle survey and vehicle data. All qualified domestic appraisal agencies have the appraisal and inspection capabilities and permits for the above-mentioned content.

The cousin of the activist car advocates lady previously publicly stated that she was worried that the “brake failure” vehicle has been repaired by Tesla, and that Tesla will automatically clean up the previous fault information after the system restarts, causing the third-party testing agency to fail to detect the truth. result.

In this regard, Tesla said that the vehicle data is that the vehicle gateway reads the signals of various components in the vehicle and stores them in encrypted driving. The stored data is recorded using encryption technology, and related data cannot be directly read, modified, or deleted. In the event of product quality disputes, Tesla will provide true and complete vehicle data in accordance with the law.

Second question:

Who will be the third party to inspect the Tesla accident vehicle?

On the evening of April 21, Tesla announced the progress of the rights protection incident on Weibo, and also urged the Zhengzhou Municipal Supervision Bureau to designate an authoritative and qualified third-party testing and appraisal agency to carry out testing and appraisal work to restore the truth as soon as possible. , “No matter what the test result is, we will accept it.”

According to Ms. Zhang’s previous introduction, on February 21, the Tesla driven by Ms. Zhang’s father had a car accident due to a brake failure and his parents were hospitalized. Ms. Zhang later requested a refund of the car, but Tesla asked the insurance company to repair the car and sell the car.

Ms. Zhang’s cousin previously stated publicly that Tesla had provided a 5.09-second background driving data showing that the Tesla’s speed reached 118.5km/h at the time of the accident, while Ms. Zhang’s cousin stated that the incident occurred at the time of the incident. During peak off hours, the 341 national highway has a speed limit of 80km/h, so the above data provided by Tesla is disagreeable.

Because of this, Ms. Zhang also refused to conduct third-party testing.

The response of the head of the Press and Publicity Department of Zhengzhou Market Supervision Bureau also confirms this point. According to reports, the Zhengdong New Area Market Supervision Bureau organized three mediations between the complainant and Tesla Motors Sales Service (Zhengzhou) Co., Ltd. on March 15, March 18, and March 24, respectively. The complainant disagreed with the third party’s technical appraisal and requested “provide complete driving data half an hour before the accident occurred”. Tesla Motors Sales and Service (Zhengzhou) Co., Ltd. refused to provide relevant data because of concerns that the data would be used by the parties for hype and publicity. Due to the large differences between the two parties, they could not reach an agreement.

On April 22, Zhengzhou Municipal Supervision Bureau and Zhengdong New District Municipal Supervision Bureau of Zhengzhou City both stated to reporters that as a mediation agency, the Municipal Supervision Bureau will not designate an appraisal agency. The appraisal agency is mainly composed of the complainant and Tesla. From time to time, third-party testing agencies with testing qualifications are all within the scope of options, not limited to Zhengzhou, as long as the two parties negotiate well, “anyone nationwide is possible.”

Three questions:

Can the identification test find out the truth of the incident?

Cui Dongshu, secretary-general of the National Passenger Car Market Information Joint Council, told reporters that the institutions currently on the market basically only test mature and long-running technologies. Tesla’s software and systems are relatively new to some institutions. It is difficult to detect, and even if it can be detected, the process is relatively long.

On April 22, a reporter from the Beijing News Shell Finance and Economics randomly called a number of automobile testing agencies. The other parties said that they can perform hardware testing for vehicles, but if there is a problem with the software or system, the existing technology of the agency cannot be guaranteed. Detected.

“Tesla has its own brand protection and has set restrictions on private data, which cannot be read by the outside world.” The service personnel of one vehicle and one inspection told reporters that it is more difficult to detect whether Tesla really has brake failure. .

The other party explained that if the vehicle brakes fail, it is generally not a hardware problem, most of which are software problems, which can be identified through OBD computer testing and read engine and gearbox data, but Tesla uses its own internal Sensors and monitoring equipment obtain data and send it back to the headquarters, which cannot be done by external technical means, “even the approximate (data) cannot be read out.”

The other party further stated that if Tesla is willing to provide historical data, such as stepping on the brakes on the highway but not decelerating, and the brake lights are on but not decelerating significantly, these data may prove that Tesla may have a brake failure problem. , But this can only be provided by the brand.

“In this case, it is still recommended to find a manufacturer.” The service staff of Pony Testing Group told reporters that if a certificate of entrustment of the car 4S shop is issued, the car can be inspected in the group, but the group can only test for hardware problems, if it is a system problem Manufacturers are required to issue data and test reports, and the group cannot conduct tests in this regard.

“We have no way to detect, because we need to use Tesla’s special computer.” The service staff of the car inspector also told reporters that the company had done vehicle inspections for Tesla before, but it was mainly in terms of hardware and software. , The company uses OBD whole-vehicle computer testing. Because Tesla has many functions, OBD testing cannot be used. “Tesla’s battery and brakes are all controlled by software, and we can’t test it”.

The service staff of the car inspector told reporters that the software inspection is not completely related to the background data, and the Tesla software cannot be inspected because the inspection agency does not have the equipment. The service staff of Pony Group also said that if you get the background data, you can directly let the manufacturer analyze it.

Four questions:

What’s the current situation of car owners who defend their rights?

On April 19, at the Tesla booth at the Shanghai Auto Show, Tesla advocated that women wear “brake failure” shirts and stood on the roof yelling “Tesla brake failure”. The incident caused crowds to watch. . The woman involved was then taken away by the staff.

The next day, the Shanghai police notified 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 at the Shanghai Auto Show. The police immediately rushed to the scene for disposal. 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 due to a consumer dispute with the brand company. During the period, the two people used arbitrary noise in the booth area, which once caused chaos on the scene. Zhang also ignored the staff’s dissuasion and forcibly climbed onto the roof of a show car, causing damage to the vehicle to a certain extent. Currently, Zhang has been sentenced to administrative detention for five days for disrupting public order, and Li has been given an administrative warning for disrupting public order.

The Beijing News Shell Finance reporter learned from the relatives of the female car owner that she is currently in detention and will be released the day after tomorrow (April 24).

On the afternoon of April 22, when Tesla disclosed the latest progress, it said that it would provide the original vehicle data half an hour before the incident to the car owner. Given that the female car owner is currently in detention, it can provide an electronic version or mail it to the female car owner’s husband.

Five questions:

What is the latest statement of the regulatory authorities?

As the Tesla owner’s rights protection event fermented, official voices 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 commitment to users must match market expectations in order to gain more consumer trust and favor. . For enterprises, it is the right way to provide high-quality products and services.

Subsequently, the Central Commission for Discipline Inspection and the State Supervisory Committee commented on the rights protection of Tesla owners and stated that companies must abide by the law, respect consumers, and respect the market. The Central Political and Legal Committee Chang An Jian also issued a document saying that Tesla must face the torture of Chinese customers. What is the responsibility? Where are you responsible?

On the night of April 21, the State Administration of Market Supervision issued a document stating that the rights protection of Tesla owners at the Shanghai Auto Show has attracted widespread attention. The State Administration of Market Supervision attaches great importance to it and has instructed the market supervision and management departments of Henan Province, Shanghai and other places to protect the legitimate rights and interests of consumers in accordance with law. At the same time, it is emphasized that enterprises must earnestly fulfill their main responsibility for quality and safety, and provide consumers with high-quality and safe products and services.

The China Consumers Association also issued a document stating that the first prerequisite for business operations is to respect consumers. Enterprises should implement product quality responsibilities in accordance with the law and take effective measures to protect consumers’ safety rights and interests. Enterprises are obliged to produce evidence to prove product safety, take measures to improve the quality of products and services, and show sincerity to resolve consumer demands involved.

Prior to this, the Zhengdong New Area Market Supervision Bureau ordered Tesla Motors Sales and Service (Zhengzhou) Co., Ltd. to unconditionally provide the rights defending vehicle Ms. Zhang with complete driving data half an hour before the accident.

After a series of voices of supervision and public opinion, Tesla began to go from “uncompromising” to an apology, and then to providing vehicle data to cooperate in restoring the truth.
