Antilock Brake (ABS) System

The Anti-lock Brake System (ABS), Fig. 3, is a brake system which controls the wheel cylinder hydraulic pressure of all four wheels during sudden braking and braking on slippery road surfaces, preventing the wheels from locking. The ABS enables steering round an obstacle with greater degree of certainty even when panic braking. Also, the ABS enables stopping in a panic brake while keeping the effect upon stability and driveability to a minimum, even on curves.

The function of the ABS is to help maintain directional stability and vehicle driveability on most road conditions. However, the system cannot prevent the vehicle from skidding if the cornering speed limit is exceeded.
In case a malfunction occurs, a diagnosis function and fail-safe system have been adopted for the ABS to increase serviceability.
