ABS Anti-lock Braking System Working Principle 3D Animation


An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles. The components of the anti-lock brake system work together to rapidly pulse the brakes and prevent them from locking up the wheels when a driver slams on the brake pedal.

Nowadays an anti lock braking system is used in almost all modern vehicles. This system prevents accidents like this, where you lose control of the steering as you apply the brakes. With ABS you will be able to steer the vehicle properly and it also reduces the braking distance. Watch the video from Learn Engineering for more info:

What is ABS? How is it able to prevent accidents due to the braking? We will explore these questions in this video.ABS includes a central electronic control unit (ECU), four wheel speed sensors, and at least two hydraulic valves within the brake hydraulics.


The ECU constantly monitors the rotational speed of each wheel; if it detects the wheel rotating significantly slower than the speed of the vehicle, a condition indicative of impending wheel lock, it actuates the valves to reduce hydraulic pressure to the brake at the affected wheel, thus reducing the braking force on that wheel; the wheel then turns faster.
