There are always smart people! In 2002, someone developed "brakeoverridesystem" (translated as "Brake Priority System" in Chinese). In fact, override is not "priority" here, but "hegemony". A more accurate translation should be "the brake is the master". I'm coming, my grandchildren are making way for me! )。 What does this mean? That is: as soon as you step on the brake, no matter what the throttle signal is, the oil supply system will immediately reduce the oil to a minimum. The technical vocabulary is "idle speed", which means that when you don't give the throttle, the engine speed is less than this speed, and the engine will stall. Exceeding this speed, the engine consumes too much fuel and is wasteful. The idle speed is generally 550-750 rpm. This difference depends on the weight of the inertia wheel inside the engine.
As far as I can remember, I know that around 2002, Mercedes-Benz bought this patent and put Mercedes-Benz on this brakeoverridesystem. In 2003, Chrysler and other American cars also bought this patent and installed this system on new cars. Then, European cars such as BMW and Volkswagen (vw) also installed this system. If you buy a 20 10 Japanese car, no other car has this system except Nissan. After 20 1 1 year, the United States may not be allowed to sell cars in the United States unless this system is installed.
Let's talk about whether there is any difference in this system first. First of all, don't say that Toyota cars caused 19 deaths. Even if they are not dead, the car accident is no small matter.
The difficulty of braking the same car, whether or not this system is installed, is very different. For example, braking at 70 mph, with or without this system, the distance to stop the car is more than 12 feet! The 6-cylinder Nissan 20 10InfinitiG37 with similar weight has a "braking system", which is 24 feet longer than the 6-cylinder Toyota 20 10 brake 100 mph!
