What is the working process of the ABS system?

The working process of the ABS system is: it performs pulsed braking at a frequency of 6 to 10 times per second, alternating between braking and releasing, replacing manual control with electronic intelligent control to prevent wheel lock-up. This ensures that the wheels always obtain maximum braking force while maintaining steering flexibility. The ABS system consists of an ABS pump, wheel speed sensors, and a brake switch. Its functions include: 1. Preventing vehicle loss of control, increasing braking distance, and improving vehicle safety; 2. Enhancing the overall braking performance of the vehicle; 3. Preventing wheel lock-up during braking; 4. Ensuring the driver can control the direction during braking and preventing rear axle skidding.
I've studied the working process of ABS, which is the core part of the anti-lock braking system. When you brake hard, the system monitors wheel speeds in real-time via sensors on each wheel. If a sensor detects that a wheel is about to lock up, the control unit instantly intervenes, commanding the hydraulic modulator to rapidly pulse the brake pressure—opening and closing valves dozens of times per second. This prevents the wheel from completely stopping, maintaining rotation. The benefit is that you can still steer by turning the wheel, avoiding loss of control and skidding on slippery surfaces. The entire process is automated, relying on the electronic control system to precisely manage the release and application of braking force, maximizing tire-to-road friction. ABS is crucial for modern vehicle safety, providing extra control especially in rainy or snowy conditions.
