That's it! Starting this year, mandatory installation!

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

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

Many car owners have doubts about this

What exactly is an EDR device?

Why install EDR?

Xiao Bu takes everyone to understand

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 event of an accident, the driver's act of stepping on the brake pedal, the EDR will save the brake signal from how many milliamps to how many milliaamperes, 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, a special researcher in the automotive industry at the Industrial Science and Technology Innovation Center of the Strategic Consulting Institute of the Chinese Academy of Sciences, introduced:

For example, the speed, longitudinal and lateral acceleration, steering wheel angle, brake throttle state, etc., especially when an accident occurs in a vehicle with auxiliary driving function, EDR can distinguish whether it is the vehicle's system failure or human operation error, which helps to determine the accident responsibility.
