In the daily use of the car, sometimes a traffic accident is caused by the improper operation of the driver or the failure of the car itself, so that the responsibility for the accident will be prevaricated. In order to better record every step of the operation of the vehicle in the process of use, the Ministry of Industry and Information Technology of the People's Republic of China's newly revised "Technical Conditions for the Safety of Motor Vehicle Operation" requires that from January 2022, newly produced passenger cars must be equipped with EDR systems, that is, on-board event data recording systems. So, what exactly is this EDR system?
A few days ago, the reporter learned in some car 4S stores in Jieyang City that the newly arrived passenger cars in the store have been installed with EDR systems, that is, on-board event data recording systems.
Jieyang Wei brand 4S store sales manager Lin Tao: the majority of consumers come to see the car, we have introduced this function, this recorder will record the data of the usual driving, all aspects of the data are recorded.
EDR refers to the on-board event data recording system, also known as the car "black box", which can record events and data during driving, such as speed, pedal condition, seat belt condition, ABS condition, acceleration, steering wheel angle and other data.
Jieyang Wei brand 4S shop technical director Lin Junli: According to different car brands, some are installed under the steering wheel, some are installed inside the dashboard, can not be seen, is to communicate through the local area network of the whole vehicle, real-time monitoring of vehicle data, transmission, and then monitoring, recording, and storage.
EDR is not the same as a dashcam, it records data, not including pictures and sounds, and this data needs to be read by professionals using professional equipment.
Jieyang Weipai 4S shop technical director Lin Junli: The process of normal vehicle driving has been recorded, and then covered, and after the vehicle has an accident collision, the data before the collision, the collision and the post-collision data are locked, which is convenient for after-the-fact testing, reading, obtaining the data of the vehicle, and after the accident, when the responsibility is determined, it is read by the police or a professional measurement agency.
The use of EDR will help to distinguish whether it is the system failure of the vehicle or the human operation error when the vehicle has an accident, so as to better find out the cause of the accident, determine the responsibility for the accident, and provide a basis for the improvement of the problem.
Jieyang Wei brand 4S store technical director Lin Junli: one is to facilitate the determination of responsibility, the other is through the data reading, you can know whether the active safety and passive safety of the vehicle can work in time at the specified time, if the time node is not correct, it can be optimized and improved.
Owner Mr. Xia: Make driving more cautious, usually when driving, will be careful, will pay attention to safe driving, do not violate traffic rules, when there is a correct driving, in case of any accident, can protect their rights and interests, this is very important, so I think this function is very good.
It is worth noting that the EDR system installed in the new car is adjusted by the manufacturer to match and adapt to the network and line of the vehicle, so the owner must not modify the vehicle after getting the new car, so as not to cause the EDR system to work due to the connection mismatch.
Jieyang Wei brand 4S store sales manager Lin Tao: It is equipped with every network module in our car, we remind consumers, do not do any modifications, including electrical wiring, in case the vehicle to record this function will be lost.
