AutoBeta(AutoBeta.net)05/26 Report--

Since the incident of safeguarding the rights of Tesla car owners, the discussion on the data and information security of intelligent vehicles has attracted wide attention from the society. A few days ago, the Secretariat of China Cyberspace Safety Association held an expert seminar on "several regulations on Automobile data Security Management (draft for soliciting opinions)".

Tesla also said on the official Weibo: Tesla is honored to discuss with industry experts on "some regulations on Automotive data Safety Management (draft for soliciting opinions)" and we firmly support the standardized development of the industry. We have set up data centers in China to localize data storage and will gradually add more local data centers. All data generated from the sale of vehicles in the Chinese mainland market will be stored in China. At the same time, we will open the vehicle information query platform to car owners. This work is in full swing, and details and progress will be reported to you one after another. Thank you for your support, we will strive to improve the user experience. Automobile data security is very important, and we firmly believe that unified and standardized management will be more conducive to the orderly and long-term development of intelligent vehicles. Tesla will make every effort to implement the automobile data safety management and ensure the data security. Thank you!

On May 12, the State Internet Information Office issued a notice on "several regulations on Automobile data Safety Management (draft for soliciting opinions)" for public consultation. The opinion draft clearly points out that in the process of designing, producing, selling, operating and managing vehicles within the territory of the people's Republic of China, the collection, analysis, storage, transmission, inquiry, utilization, deletion and provision of personal information or important data abroad (hereinafter collectively referred to as processing) shall comply with the requirements of relevant laws and regulations and these provisions.

In response to the notice issued by the Internet Information Office on "several regulations on Automobile data Safety Management (draft for soliciting opinions)" for public consultation, many netizens expressed support. As most of the models sold on the market are equipped with cameras, radar and other sensor devices, information will be constantly collected in the daily use of vehicles to improve the operation of intelligent systems and promote self-driving technology. but invisibility also brings a lot of privacy and information security concerns.

The reason why Tesla caused data security concerns in China, Tesla collected driving data are directly transmitted to the United States, on the one hand, question the confidentiality of user data, on the other hand, it may bring hidden dangers to national security. In addition, after Tesla's accident, when users asked Tesla to provide new car data, they needed a letter from the regulatory department to provide it, resulting in users' dissatisfaction with Tesla's service attitude. Even if Tesla released the data to the public, the integrity of the data was also controversial.

In the rights protection incident of "Tesla Shanghai Auto Show," which attracted much attention, the rights protection car owner said that he had asked Tesla for driving data many times, but Tesla refused to provide driving data, and finally had no choice but to go to the Shanghai Motor Show booth to protect his rights. Tesla was forced to provide complete driving data half an hour before the accident to the rights protection car owners under the pressure of many state media and regulatory authorities, but the rights protection car owners also questioned the driving data. It is said that the data provided by Tesla is incomplete, and a series of specific project parameters, such as brake pedal displacement, throttle pedal displacement, motor torque, car body excitation, energy recovery, working status of power assist system, ESP working status, and so on, are not reflected in the data.

To this end, Tesla decided to store the data in China and open the data query platform at the same time. According to previous reports, Tesla will launch the event data recorder EDR query kit this year, which allows car owners to query vehicle driving data and generate corresponding data reports to help car owners better understand the cause of the accident.

What is EDR? EDR, whose full name is Event Data Recorder, usually starts work when the vehicle state changes drastically. Its function is to record some data related to vehicle dynamics and safety in the event of a collision, including vehicle speed, ABS status, steering wheel steering angle, engine state, airbag state, seat belt status, throttle position, driving assistance system status, and vehicle speed changes after a collision. These data can effectively restore the real situation at the time of the incident. If Tesla online event data recorder EDR query software, this will also effectively solve the car owners' doubts about the vehicle collision. However, at present, only North American Tesla owners can get EDR-related software for free, and the cables necessary to read the data cost US $1200. In other words, it is not easy for domestic consumers to query driving data on their own in a short time.

As for Tesla's establishment of a data center in China to achieve domestic data storage, some netizens said that this is Tesla's low profile to achieve domestic data storage, which can also avoid a lot of unnecessary misunderstandings.

Tesla's vice president of foreign affairs said in an interview with the media that "there is no way to compromise, which is a necessary process for the development of new products." Nowadays, Tesla accidents occur frequently, especially after the auto show rights incident, many media named and criticized. Tesla seems to have put down his arrogant posture and began to carry out a series of actions on driving data and product issues that consumers are concerned about. various signs show that in this special market of China, Tesla is making a series of compromises and adjustments.

According to the data, Tesla sold 25845 vehicles in China in April, compared with 35478 in March, down 27.15% from the previous month. Tesla Model 3 and Model Y sold 6440 and 5516 respectively. In addition, a total of 6.9 electric vehicles were delivered in the Chinese market in the first quarter of this year, with revenue of $3.043 billion (19 billion yuan), accounting for about 30 percent of the world's total revenue, according to Tesla's financial results. No matter what the data, the importance of the Chinese market is self-evident to Tesla.

Tesla Shanghai Super Factory is Tesla's first overseas factory. About 30,000 to 40,000 cars are exported to countries such as Europe and Japan every quarter. Although the United States is Tesla's largest market, China is also particularly important to Tesla. Therefore, no matter whether it has been named by the central media recently or regulated by policy and by netizens' public opinion, Tesla's attitude has gradually changed. Of course, this change is also attributed to consumers, which taught Tesla in the Chinese market that it is impossible to use "no compromise" and "emotional card" alone.
