The anti-lock braking system limits the pressure generated in the hydraulic brake actuator so that the amount of slip is optimal

The operation of this system should be separate for each wheel.

The system must immediately respond to every change in the surface (traction coefficient) and the load on the car.

The anti-lock braking system prevents the wheels from locking during heavy braking, thereby reducing the braking distance.

The grip force between the wheels and the road in this case is greater if the wheels continue to rotate during braking.

Even with full braking, the car remains steerable.

Rate sensors, one for each wheel, measure wheel speed.
