What is the ABS Anti-lock Braking System?
2 Answers
ABS Anti-lock Braking System is a system that automatically controls the braking force during vehicle braking to prevent wheel lock-up, keeping the wheels in a rolling-sliding state to ensure maximum adhesion between the wheels and the ground. A constantly illuminated ABS light does not affect normal vehicle braking and will not cause brake failure. However, in emergency situations requiring sudden braking, the ABS system will not function. Causes of ABS light warnings include: 1. Faulty vehicle wheel speed sensor; 2. Wheel speed sensor faults can be divided into two types: one is ABS warning caused by a broken wheel speed sensor, and the other is ABS warning caused by a dirty ABS sensor, which prevents the sensor from detecting wheel speed; 3. Faulty wheel speed sensor wiring.
The ABS (Anti-lock Braking System) is an automotive safety device that prevents wheels from completely locking up during emergency braking. It monitors speed changes via sensors on the wheels. When detecting a wheel is about to lock, the system automatically releases brake pressure slightly and then reapplies it rapidly, repeating this process multiple times per second. This allows the wheels to maintain slight rotation, ensuring vehicle stability and preventing skidding or spinouts. When I slammed the brakes on the highway, I felt slight pedal vibrations as ABS engaged while still maintaining steering control to avoid obstacles – especially useful on wet or snowy roads. Most modern vehicles now come standard with ABS, often integrated with other systems like electronic stability control, reducing accident rates by 20-30%. New drivers are advised to practice emergency braking in open areas to experience ABS activation and improve safety awareness.
