From 2022 onwards, EDR will be mandatory for new cars!
Previously, the Ministry of Industry and Information Technology's newly revised "Technical Conditions for the Safety of Motor Vehicle Operation" required that newly produced passenger cars from January 2022 must be equipped with an EDR system, that is, a driving event recorder, which is called a black box device for cars, which can record vehicle operation data before and after the accident.
In the future, the "Rashomon" events involving intelligent driving, such as Tesla brake doors, are expected to be "hammered" through the data of the black box.
"Motor Vehicle Operation Safety Technical Conditions" National Standard No. 2 Amendment Order
In this regard, many car owners have questions: what is the device of EDR? Why install EDR? Let's take a look at it now.

The National Standard No. 2 amendment to the "Technical Conditions for the Safety of Motor Vehicle Operation" stipulates that from January 1 this year, newly produced passenger cars in China should be equipped with "EDR" that meets the requirements. This device, commonly known as the car black box, is triggered when the vehicle collides or the speed changes drastically, and the recording begins.
Cao Guangping, an independent researcher on new energy vehicles: In the accident, the driver's behavior of stepping on the brake pedal, EDR will save the brake signal from how many milliamperes to how many milliamps, including deceleration, finally stop, the whole process will be recorded.
In addition to recording the driver's handling data, EDR also records the vehicle status.
Lu Wenliang, Special Researcher of the Automotive Industry of the Industrial Science and Technology Innovation Center of the Chinese Academy of Sciences Strategic Consulting Institute: For example, the speed of the vehicle, the acceleration of the longitudinal and horizontal directions, the angle of the steering wheel, the state of the brake throttle, etc., especially when the vehicle with the auxiliary driving function is involved in an accident, EDR can distinguish whether it is the system failure of the vehicle or the human operation error, which helps us to determine the responsibility for the accident.
At present, 99% of new cars listed in the United States are equipped with EDR, and about 10% of new cars in mainland China are equipped. BMW, Mercedes-Benz and other luxury cars, as well as new energy vehicles such as Weilai and BYD, are mostly equipped with EDR, and the average cost is about 1,000 yuan.
Cui Dongshu, secretary general of the China Passenger Vehicle Association, said that next year's large-scale equipping of new cars with EDR will not cause a rise in car prices.
Cui Dongshu, secretary general of the China Passenger Car Association: The cost is relatively low, that is, the concept of 300 to 500 yuan, manufacturers can overcome this impact, will not increase the cost of car purchase for consumers.
