An anti-lock braking system or anti-skid braking system (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding.
ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces; however, on loose gravel or snow-covered surfaces, ABS can significantly increase braking distance, although still improving vehicle steering control.
According to the NHTSA,
“ABS works with your regular braking system by automatically pumping them. In vehicles not equipped with ABS, the driver has to manually pump the brakes to prevent wheel lockup. In vehicles equipped with ABS, your foot should remain firmly planted on the brake pedal, while ABS pumps the brakes for you so you can concentrate on steering to safety.”
How does an ABS wheel sensor work?
Even some vehicles without anti-lock brake systems (ABS) will use wheel speed sensors as the vehicle speed input for the engine control module and transmission control module. The traditional wheel speed sensor consists of a tone wheel (sometimes called a trigger wheel) plus a magnetic pickup. … The sensor is stationary.
What is the meaning of ABS in cars?
ABS stands for the anti-lock braking system on a car. This prevents brakes from locking up when they are suddenly applied on a slippery road.
How does ABS work on a motorcycle?
An Anti-lock Braking System (ABS) works to prevent a motorcycle’s wheel, or wheels, from locking during braking. ABS uses speed sensors on both wheels to accurately determine wheel speed, as well as sensors to determine when a wheel is about to lock.
What does it mean when the ABS light comes on the dashboard?
What is EBD and ABS?
Electronic brakeforce distribution (EBD or EBFD) or electronic brakeforce limitation (EBL) is an automobile brake technology that automatically varies the amount of force applied to each of a vehicle’s wheels, based on road conditions, speed, loading, etc.
What is the wheel speed sensor?
A wheel speed sensor, also called an “ABS sensor,” is part of the Anti-lock Brake System (ABS). … When the brake is applied, the ABS control module reads the speed data from the speed sensor and sends the correct pressure to each wheel to prevent any sliding/skidding (wheels locking up).
