ABS Components
System Description (cont'd)
Features
When the brake pedal is pressed during driving, the wheels can lock before the vehicle comes to a stop. In such an
event, the maneuverability of the vehicle is reduced if the front wheels are locked, and the stability of the vehicle is
reduced
if
the rear wheels are locked, creating an extremely unstable condition. The ASS precisely controls the slip
rate aftha wheels to ensure maximum grip force from the tires, thereby ensuring the maneuverability and stability of
the vehicle.
The ABS calculates the slip rate of the wheels based on the vehicle speed and the wheel speed, then it controls the
brake fluid pressure to reach the target slip rate.
