Beside the brake piston (the caliper of the brake disc, inside is the brake piston), ABS work is to ensure that the brake piston and brake disc are not stuck, to ensure that they are on the edge of sliding friction and static friction. Most of them are monitored by an inductive sensor. The abs sensor outputs a set of quasi-sinusoidal AC signals through the action of a ring gear that rotates synchronously with the wheel. The frequency and amplitude are related to the wheel speed. The output signal is transmitted to the ABS electronic control unit (ECU). ), real-time monitoring of wheel speed.
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 car 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.
