From 2022 onwards
New cars are forced to install EDR!
Previously
Newly revised by the Ministry of Industry and Information Technology
"Technical Conditions for the Safety of Motor Vehicle Operation"
Requirements are from January 2022
Newly produced passenger cars must be equipped with EDR systems
i.e. driving event logger
This device is called the black box of the car
Vehicle operation data before and after the accident can be recorded
future
Tesla brake doors etc. are involved
The "Rashomon" incident of intelligent driving
It is expected to be confirmed by 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 doubts:
What exactly is an EDR device?
Why install EDR?
The Ministry of Industry and Information Technology publishes relevant standards / the website of the Equipment Center of the Ministry of Industry and Information Technology
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 of new energy vehicles, introduced: 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 milliamperes, including deceleration, finally stop, the whole process will be recorded.
In addition to recording the driver's control data, EDR will also record the state of the vehicle, the Chinese Academy of Sciences Strategic Consulting Institute Industrial Science and Technology Innovation Center Automotive Industry Special Researcher Lu Wenliang introduced: for example, speed, longitudinal and lateral acceleration, steering wheel angle, brake throttle status, etc., especially when the auxiliary driving function of the vehicle accident, EDR can distinguish whether it is the vehicle system failure, or human operation error, help us to determine the responsibility of 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: 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 consumer car purchase.
