Drive Anti-Slip System (ASR)
The complete and extended function of the anti-lock braking system of the car is the driving anti-skid system (ASR), and the two systems have many common components. The system uses a speed sensor on the drive wheel to sense whether the drive wheel is slipping, and when slipping occurs, the control element reduces the speed by braking or via the accelerator so that it no longer slips. It is essentially a speed regulator, which can improve the longitudinal adhesion between the wheel and the road surface, provide the maximum driving force, improve its safety, and maintain the directional stability of the car when the speed changes sharply in the starting and cornering.
