Antilock Brakes / Traction Control Systems: Description and Operation

ANTI-LOCK BRAKE SYSTEM (ABS)

DESCRIPTION






• The ABS is a brake system which controls the brake cylinder hydraulic pressure of all four wheels during sudden braking and braking on slippery road surfaces, preventing the wheels from locking. This ABS provides the following benefits:
(1) Enables steering round an obstacle with a greater degree of certainty even when panic braking.
(2) Enables stopping in a panic brake while keeping the effect upon stability and steerability to a minimum, even on curves.
• The function of the ABS is to help maintain directional stability and vehicle steerability 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.
