The majority of car owners have noticed that from 2022, new cars are mandatorily installed with EDR!

Previously, the Ministry of Industry and Information Technology's newly revised "Technical Conditions for the Safety of Motor Vehicle Operation" required that from January 2022, newly produced passenger cars must be equipped with an EDR system, that is, a driving event recorder, which is known as a car black box device that can record vehicle operation data before and after the accident, and the future "Rashomon" incident involving intelligent driving is expected to be "hammered" through the data of the black box.

In this regard, many car owners have questions, what is the device of EDR? Why install EDR? Xiaobian takes you 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.
