•  ABS control occurs when wheel slip is determined by the electronically controlled brake unit CM (based on the four ABS wheel-speed sensors). Then, the electronically controlled brake unit HU inlet and outlet solenoid valves are operated and brake fluid pressure is controlled accordingly to prevent wheel lock-up.

•  Use of ABS control during emergency braking or on slippery road surfaces allows directional stability to bemaintained, steerability ensured, and stopping distance to be reduced.

•  The ABS control system has independent wheel control.

•  When the electronically controlled brake unit CM determines wheel slip conditions based on the signals from the ABS wheel-speed sensors during braking, the electronically controlled brake unit CM operates the electronically controlled brake unit HU inlet and outlet solenoid valves, reducing and maintaining brake fluid pressure in accordance with the wheel slip factors. Then, when the wheel slip condition has passed, brake fluid pressure is increased and maintained, ensuring braking with a constantly stable brake force.
