5 ABS

General

ABS
In the anti-lock brake system (ABS), the wheel movement
is recorded using a proximity-type arrangement with an
exciter ring attached to the hub and a sensor (speed sen-
sor) that generates the pulses.
The wheel speed is continuously reported to the central
control electronics from each wheel in this way. It has a
complex program for processing the received informati-
on about the movement behaviour of the wheel and for
calculating and logically linking the control signals. Using
the pressure control valves assigned to each wheel, it
adjusts the air pressure and therefore the braking of each
individual wheel (depending on the ABS system).

Almost all BPW axles can be retrofi tted with ABS wit-
hout any problem. Simply attach the exciter rings, sensor
brackets, sensors and attachment parts included in the
supplementary installation kit to the axle according to
the supplied mounting drawing and connect them to the
vehicle electronics.
