What are the components of the ABS system?

ABS system mainly consists of three parts: sensors, electronic control device and actuator. Its working principle is: the speed sensor detects the wheel speed, and then transmits the wheel speed signal to the microcomputer. The microcomputer controls the slip rate of the wheel by repeatedly reducing or increasing the braking pressure on the wheel according to the input wheel speed, so as to keep the wheel rotating. ABS (Antilocked Braking System) is an automotive safety control system with the advantages of anti-skid and anti-lock. Modern cars are equipped with a large number of anti-lock braking systems. ABS not only has the braking function of ordinary braking system, but also can prevent wheel lock, so that the car can still steer in the braking state, ensure the braking direction stability of the car, prevent side slip and deviation, and is currently the advanced braking device with better braking effect on the car.
Having driven for so many years, ABS is truly a life-saving system. Simply put, ABS mainly consists of four core components. The first is the wheel speed sensor, installed near the wheels, which monitors the rotation speed of each wheel in real time. The second is the electronic control unit, acting like the car's intelligent brain, analyzing the data from those sensors. Once it detects a wheel is about to lock up, it takes immediate action. The third is the hydraulic unit, which includes valves and pumps, responsible for adjusting the pressure of the brake fluid to prevent wheel lock-up. The fourth is the control wiring harness, transmitting signals from one part to another. This system usually operates silently, but when braking on rainy or snowy days, ABS prevents tire skidding, keeping the car stable and significantly reducing the risk of accidents. I remember one time braking hard on a slippery road—ABS kicked in, and the car stopped smoothly. It was such a relief. I recommend that car owners clean the sensors regularly when washing their cars to prevent dust from affecting their performance.
