In addition to the conventional brake system with two diagonally split brake circuits, the anti-lock brake system (ABS) consists of an ABS hydraulic control unit with an integrated electronic control unit, four wheel speed sensors and the ABS warning indicator in the instrument cluster.
Electronic brake force distribution software is integrated in the electronic control unit, which electronically regulates and optimizes the hydraulic pressure applied to the brake calipers on the front and rear axles in accordance with the operating conditions.
Function
The ABS is a closed loop control system which prevents the wheels from locking up under braking and therefore maintains steerability and driving stability in extreme situations within the physical limits.
