What does the ABS system mean?
2 Answers
ABS system refers to the Anti-lock Braking System, which consists of an ABS pump, wheel speed sensors, and a brake switch. Its working principle is: during emergency braking, relying on highly sensitive wheel speed sensors installed on each wheel, it detects wheel lock-up, and the computer immediately controls the pressure regulator to release pressure from the wheel's brake caliper, preventing wheel lock-up. The functions of the ABS system are: 1. To prevent vehicle loss of control, increase braking distance, and improve vehicle safety; 2. To enhance the overall braking performance of the vehicle; 3. To prevent wheel lock-up during braking; 4. To ensure that the driver can control the direction during braking and prevent rear axle skidding.
ABS stands for Anti-lock Braking System. Having worked in a repair shop for over a decade, I can honestly say this system is incredibly practical. It prevents wheels from completely locking up during hard braking, allowing you to maintain steering control. Just think about older cars without ABS - a hard brake would cause the vehicle to skid uncontrollably with longer stopping distances. ABS uses wheel speed sensors to detect impending lock-up, then rapidly adjusts brake pressure via pump valves to keep the wheels slightly rotating. This proves especially effective on wet, snowy, or gravel surfaces, significantly reducing accident risks. If a vehicle's ABS warning light comes on, it could indicate sensor or pump valve issues that require immediate inspection - otherwise you might experience brake judder or instability during braking. Safety is the top priority in driving, and ABS has essentially become standard equipment on all new vehicles today.
