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
The "Rashomon" incident involving intelligent driving
Expected to pass
The data of the black box proves that "one hammer is final"
"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?
Xiaobian will take you to understand it immediately
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 on new energy vehicles: In the accident, the driver stepped on the brake pedal, and the EDR will save the brake signal from how many milliamperes to how many milliamps, including deceleration and final stop, and the whole process will be recorded.
In addition to recording the driver's handling data, EDR also records the vehicle status.
Lu Wenliang, a special researcher in the automotive industry at 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 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 Car Association, introduced that the large-scale equipping of new cars with EDR will not cause price increases.
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 purchases for consumers.
