There is a basis for the determination of responsibility for safety accidents

　　From this year, new cars will be forced to install "black boxes"

　　From January 1, 2022, new cars will be required to install EDR.

　　In the new year, new regulations for the automotive industry have also been released and implemented.

According to the requirements of the National Standard No. 2 Amendment to the "Technical Conditions for Motor Vehicle Operation Safety" newly revised by the Ministry of Industry and Information Technology, starting from January 1, 2022, newly produced passenger cars are required to be equipped with EDR (ie Event Data Recorder, an event data recorder). system) or equipped with a compliant DVR (vehicle video driving recording system).

　　EDR can record vehicle operation data before and after the accident. When the vehicle collides or changes drastically in speed, it will be triggered and start recording.

EDR may provide an effective basis for "Rashomon" incidents involving intelligent driving such as Tesla's brake door.

　　What does EDR do?

　　Helps understand accident-related data to drive information security and regulatory advancements in smart cars

　　GB 7258-2017 "Technical Conditions for Motor Vehicle Operation Safety" (Amendment No. 2) stipulates that "passenger vehicles shall be equipped with an event data recording system (EDR) that complies with the provisions of GB 39732; In-vehicle video driving recording system (DVR), shall be deemed to meet the requirements", which will be implemented for newly produced vehicles from January 1, 2022.

　　Why is EDR mandatory?

Mr. Liu, who used to be engaged in auto insurance survey and damage assessment, told the Red Star Capital Bureau that EDR can record driving data, especially the data of dozens of seconds before and after the accident.

At present, driving recorders are mainly used in China, most of which are superficial GPS data and video data.

　　"In the era of fuel vehicles, the cost-effectiveness of EDR is not high. However, with the rise of new energy vehicles, complex electronic control systems and automatic driving technology, there are potential safety hazards such as electric vehicle system failure, driver misoperation, and network information security. EDR become a necessity.”

　　Mr. Liu explained that there are few mechanical accidents of fuel vehicles. In most cases, the cause of the accident and the attribution of responsibility can be determined only through traffic monitoring, collision conditions, brake traces, testimony from both parties, and simple driving recorder images.

　　In the era of electric vehicles, in addition to hardware problems, software problems can also occur.

For example, in Beijing in August 2016, the autopilot system of a Tesla Model S failed to recognize the black vehicle ahead, resulting in a collision; in July 2016, a Tesla Model X suddenly turned to the right in the United States and crashed into the isolation Guardrail, when the car owner turned on automatic driving; South Korea's Hyundai KONA electric vehicle IEB (Integrated Electronic Brake) motor control logic program was imperfect, resulting in brake failure...

　　Mr. Liu told the Red Star Capital Bureau that both the EDR national standard and the automotive big data interactive blockchain platform will help car owners understand accident-related data, make vehicle information open and transparent, and promote the progress of information security and supervision in the field of smart cars.

　　As early as 2006, the National Highway Traffic Safety Administration (NHTSA) issued the definition and related standards of EDR, and required that from September 2014, all vehicles sold in the United States need to be equipped with EDR.

According to the analysis of Zosi Production and Research, 99% of new cars launched in the United States in 2019 are equipped with EDR.

　　The EDR standard in Europe is similar to that in the United States, requiring mandatory installation on all new cars from March 2022, and on stock cars from March 2024.

South Korea has mandatory installation (including stock cars) since December 2015, and Japan has an independent EDR standard, but it is not mandatory.

　　Will car prices go up?

　　The unit price of EDR equipment is not high

　　Experts don't think it will cause car prices to rise

　　Will mandatory EDR increase car prices?

Red Star Capital noticed that the unit price of EDR equipment is not high.

According to the prospectus of Hongquan IOT (699288.SH), the market price of a single tachograph is around RMB 500.

　　However, CDR, a tool for reading EDR data, is more expensive.

Mr. Liu told the Red Star Capital Bureau that the reading tool (CDR) of the EDR system is mainly provided by Bosch. The entry-level CDR price is 7,100 US dollars per set, and there is an annual software upgrade fee of 1,000 US dollars. The professional version costs 18,000 US dollars per set. ; The price of CDRs produced by Kia, Hyundai, Subaru, Mitsubishi and other car companies themselves is also 6300-7000 US dollars / set, and software maintenance fees are paid every year.

　　Cui Dongshu, secretary-general of the China Passenger Car Association, said that large-scale EDR equipment in new cars will not cause car prices to rise.

"The (EDR) cost is relatively low, that is, 300 to 500 yuan. Manufacturers can overcome this impact without increasing the cost of buying cars for consumers."

　　Mandatory EDR installation will also create a huge market.

　　CITIC Securities believes that because DVR equipment that meets the requirements of GB/T 38892 exceeds EDR equipment in terms of cost and equipment complexity, it is judged from the Ministry of Industry and Information Technology's "Road Motor Vehicle Manufacturers and Products Announcement" that most car companies choose EDR solutions.

According to the 23 million new passenger cars in 2022, it is conservatively estimated that there will be an incremental market of more than 80% of the new car installations in the market after 2022, which corresponds to a market space of 9.2 billion yuan.

　　The research report of Huaxi Securities also shows that the Chinese passenger car market has basically stabilized at around 20 million in the past five years. Assuming that with the rapid popularization of EDR, equipment prices will drop sharply, the price is expected to stabilize at around 500 yuan, and the market space for EDR equipment is conservatively estimated. At around 10 billion yuan, industrial chains such as sensors, storage, MCU, and backup batteries have benefited a lot.

　　What is EDR?

　　In aviation accidents, we often hear a word "black box", and EDR can be called the "black box" of the car.

It is used to record the key data of the car's operation in the three stages before the collision, during the collision and after the collision, such as vehicle speed, vehicle collision acceleration, steering angle of the steering wheel, engine operation status, airbag status, driver assistance system, driver in Important information such as reaction actions when an event occurs.

　　Why are passenger cars required to be equipped with EDR?

　　At present, with the popularity of automobiles, incidents about car safety issues rarely occur.

EDR can record the relevant data of the vehicle at the time of the collision event.

On the one hand, it can objectively judge the causes of collision incidents, ensure judicial justice and protect public interests; on the other hand, it can provide a basis for improving vehicle safety systems, avoid similar collision incidents, and provide vehicle safety.

　　What is the difference between an EDR and a dash cam?

　　The driving recorder is generally based on data such as time, speed, and video images, and the data is relatively basic and superficial.

The data recorded by the EDR is more specific, such as the acceleration of the vehicle during the collision, the working state of the engine, and the various operations performed by the driver during the accident.

　　How is the progress of the EDR standard?

　　It is reported that the automotive EDR was originally born in the United States General Motors.

European standards are similar to those in the United States, requiring mandatory installation of EDR for new cars after March 2022, and also for stock cars after March 2024.

South Korea has mandatory installation (including stock cars) since December 2015; Japan has relevant standards but has not enforced them.

　　The Chinese EDR standard (C-EDR) was finalized at the end of November 2019.

According to the Ministry of Industry and Information Technology, the EDR function requirements are divided into two stages: A and B. In the first stage, the EDR on newly produced vehicles must meet 23 items of data such as longitudinal acceleration, ABS status, engine speed, seat belt status, and pedal position. The next stage can read data or will increase to 50 items.

In the future, supervision will also intensify efforts to improve the corresponding rules and regulations, protect data security, and safeguard the legitimate rights and interests of consumers and car companies.
