What Components Make Up the ABS System?

[DelWilliam]

ABS system mainly consists of three parts: sensors, electronic control unit and actuators. Its working principle is: using speed sensors to detect wheel speed, then transmitting the wheel speed signals to the microcomputer. The microcomputer controls the wheel slip rate by repeatedly reducing or increasing the braking pressure on the wheels based on the input wheel speed, maintaining wheel rotation. ABS (Anti-lock Braking System) is an automotive safety control system with advantages such as anti-skid and anti-lock functions. Modern vehicles are widely equipped with ABS, which not only maintains the braking function of conventional braking systems but also prevents wheel lock-up. This allows vehicles to maintain steering capability during braking, ensuring directional stability and preventing side-slip and deviation. Currently, ABS represents one of the most advanced braking devices with superior braking performance in automobiles.
