The ABS is a closed loop control system in the
brake system which prevents the wheels from

Wheel
speed sensors
In addition to the conventional brake system with
two diagonally split brake circuits, the ABS consists
of an ABS hydraulic unit with integrated control
unit, four wheel sensors and the ABS warning lamp
in the instrument cluster. locking up under
braking and therefore maintains
steerability and driving stability in extreme
Electronic brake force distribution is integrated in
the software of the ABS control unit', which
electronically regulates and optimises the pressure
applied to the wheel brakes on the front and rear
axles in accordance with the operating conditions.
ABS control unit
The ABS control unit continuously compares stored
physical deceleration values with those detected
by the wheel sensors. This allows the lock-up
tendency of each wheel to be detected separately.
If the ABS control unit detects that a wheel is
threatening to lock up, then the corresponding
hydraulic valves in the valve block are either closed
or opened.
The ABS control unit then also passes on the
vehicle speed signal obtained from the wheel sensors to the Powertrain Control Module (PCM).
