From 2022 onwards
New cars are forced to install EDR!
Previously, the Ministry of Industry and Information Technology newly revised
"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
From January 1, newly produced passenger cars in China will be equipped with EDR. The device, known as the car black box, records vehicle operation data before and after the accident. In the future, the "Rashomon" incident involving intelligent driving, such as Tesla's brake door, is expected to be "hammered" through the data of the black box.
"Motor Vehicle Operation Safety Technical Conditions" National Standard No. 2 Amendment Order
Many car owners have doubts about this
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 of new energy vehicles, introduced:
Cao Guangping: 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 control data, EDR will also record the status of the vehicle, 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, introduced:
Lu Wenliang: For example, the speed of the vehicle, the acceleration of the longitudinal and lateral 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: 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.
Starting this year
All kinds of accident disputes over new cars will be well documented
