What are the EDR regulations for vehicles?
2 Answers
EDR is the black box of a vehicle, and the latest regulations may require nationwide installation. The role of the black box: As the sole carrier recording the truth of a crash, the irreplaceability of the "black box" has been proven in the aviation field. Now, in another mode of transportation—cars—the term "black box" is being mentioned again. With increasing attention to car accidents and the growing number of vehicles, the importance of the "black box" as "ironclad data evidence" is becoming more prominent. The difference between EDR and dash cams: EDR can provide more information than a dash cam. According to the EDR standard, the recorded data elements are divided into Class A and Class B. There are 23 Class A data elements, including longitudinal acceleration, ABS status, clip flag, accelerator control (pedal) position, etc. Class B elements consist of 50 items, including lateral acceleration, brake pedal position, automatic emergency braking (AEB) system status, airbag status, etc.
Hey, I've encountered this issue before while driving. The car's EDR, which stands for Event Data Recorder, is that accident recorder mandated by regulations to be installed in new vehicles. It records information like speed, braking, and airbag deployment, primarily to prevent evidence tampering. I remember a minor accident where the insurance company pulled the data for investigation—it seemed pretty accurate, but I have some privacy concerns, like whether others can easily access my driving habits. Regulations vary by country; for instance, China has standards requiring 15 seconds of data recording, aiming to reduce traffic accident disputes. Overall, it's quite practical for us regular drivers, not only protecting our rights but also promoting safe driving awareness. I often remind friends to check the EDR section in their vehicle manuals to ensure they know their rights.
