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 an EDR system
i.e. driving event logger
This device is called the black box of the car
Before and after the accident can be recorded
Vehicle operation data
future
Tesla brake doors etc. are involved
The "Rashomon" incident of intelligent driving
It is expected to be ironclad by the data of the black box
"One Shot"
"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?
Let's take a look at it now
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, 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 Of Industrial Science and Technology Innovation Center Automotive Industry Distinguished Researcher Lu Wenliang introduced: "For example, the speed, the longitudinal and lateral acceleration, the steering wheel angle, the brake throttle state, etc., especially when the auxiliary driving function of the vehicle has an accident, EDR can distinguish whether it is the vehicle system failure, or 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 said: "Equipped with EDR 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." ”
