Body Stability System (ESP) is a very important active safety configuration in automobiles. Its function is to prevent sideslip and out of control by automatically braking other wheels and intervening in the engine management system when the front wheels or rear wheels with driving and steering functions slip when the vehicle turns at high speed.
The English name of body stability system is not only ESP, but also a patent registered by Bosch Company in Germany. In fact, its real scientific name should be ESC(Electronic Stability Control), but the name ESP is used to it, so it has not been renamed. Other car manufacturers also have systems with the same function,
but with different names. Honda is called VSA, Toyota is called VSC, Nissan VDC and BMW is called DSC.
The working principle of p>ESP is a more advanced function derived from ABS braking and ASR traction control system. It can judge the driving condition of the car through sensors distributed on the car and intervene the power. It can brake one or more wheels separately at the same time, thus maintaining the stability of the driving condition and the controllability of the direction.
ESP is the electronic stability system of the car body, which maintains the stability of the car body, but it can't improve the physical limit of the car. The reason why ESP can improve the active safety and keep it from getting out of control is because it can't bring the performance of the car to the limit for most drivers, so ESP only ensures that the control of the car is not affected by its own wrong operation and helps drivers keep the car within the dynamic limit.
