From 2022, EDR will force new cars on the road. What is the use of it? What are you most afraid of in a fast and intelligent economic era? There is no doubt that accidents are one of them. I think? Black box? The birth of is very useful. After all, there are more and more vehicles now, and with the increase of the number of cars, vehicle accidents are inevitable. So? Black box? It can help us to judge whether the driver is safe when driving, and the whole process will be recorded.

Does the driver still have privacy? Really? Black box? Our driving is unaffected by birth. I believe in the future, drivers should be able to accept it. After all, every time a policy changes or a new policy is added, there are always some people who can't accept it in a short time. The birth of EDR is undoubtedly similar to an item that reminds you of driving safety at real time.

What can a car black box do? Usually, when people talk about black boxes, they think of airplanes. The plane can record some key data during the trip, so it is much more convenient to trace the source of the accident. It is fireproof, waterproof and impact-resistant. In fact, the black box is not black, but bright orange, with striking reflective strips on it, which is set up for easier identification after the plane crash. The black box in the car naturally played this role. After the engine is started, 73 items of information including Class A and Class B can be recorded, including but not limited to vehicle speed, acceleration, steering wheel angle, airbag status, brake and throttle status, etc. If it is a modern smart car, it can also distinguish whether the car's system is faulty or the driver's operation is wrong, which is helpful for people to determine the responsibility. With the development of the times, black box is a very important tool for drivers. I believe that with it, drivers and friends will pay more attention to safety when driving.
