What does it mean when a car is equipped with an ABS system?

[Robles]

When a car is equipped with an ABS system, it refers to the Anti-lock Braking System. Its function is to automatically control the braking force during vehicle braking, preventing the wheels from locking up and maintaining a rolling-sliding state to ensure maximum wheel-to-ground adhesion. The performance of the Anti-lock Braking System is not only related to its structure but also closely tied to its control strategy and control methods. Currently, there are three commonly used ABS control strategies for regulating wheel braking pressure: individual wheel control, low-select control, and high-select control. The control methods of the Anti-lock Braking System include various approaches such as PID control, sliding mode variable structure control, fuzzy control, and robust control methods.
