Description and Operation

Description

Hydraulic control unit (HCU)

Rear wheel speed sensors

Front wheel speed sensors

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.
