8D0927803B ABS Sensor for Audi A4 Avant

ABS is of course useful. Basically, every car is equipped with ABS as standard equipment. Its Chinese name is “anti-lock braking system”, which is an improved technology based on conventional braking devices. ABS works by relying on the speed sensor mounted on the wheel and the speed sensor on the body to control the braking force through the computer. When an emergency brake occurs, the computer immediately commands the pressure regulator to the wheel. The brake cylinder is decompressed to make the wheel return to rotation; the working process of ABS is actually the cycle work of “lock-release-lock-release”, and the tire of the car is always in the critically-rolled intermittent rolling state. It can effectively overcome the running, skidding, tail and other situations during emergency braking to prevent the body from losing control.

The most important function of the ABS sensor is not to shorten the braking distance, but to keep the directional stability of the car as much as possible while braking. When ABS is active, the friction between the wheel and the road surface is rolling friction, which will make full use of the maximum adhesion between the wheel and the road surface to brake, thereby increasing the braking acceleration and shortening the braking distance, but the most important thing is to ensure the cars Directional stability. When ABS works, it is equivalent to a high frequency to brake. Therefore, if the brake pedal is stepped on in an emergency, the brake pedal will be felt to vibrate, and the buzzing sound from the master cylinder will be heard. This is the normal operation of the ABS. The master cylinder continuously adjusts the brake pressure to produce a continuous feedback force to the brake pedal.
