What is the function of anti-lock braking systems (ABS)?

The function of anti-lock braking systems (ABS) is to prevent the wheels from locking up during hard braking. This is crucial for maintaining steering control and stability when sudden stops are necessary. When a driver applies the brakes forcefully, ABS detects the onset of wheel lock-up and automatically modulates brake pressure to each wheel. This means that while the driver can maintain maximum braking force, the system prevents the wheels from stopping completely, allowing the vehicle to continue to be controllable and steerable.

This technology enhances safety, especially in slippery conditions such as rain or snow, where locked wheels could lead to skidding. By ensuring that the wheels continue to rotate, ABS not only helps to maintain better control of the vehicle but also reduces stopping distance on wet or icy roads compared to conventional braking systems. This dramatically improves the overall effectiveness and safety of a vehicle during critical braking situations.
