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
sensor) that generates the pulses.
As a result, the wheel speed of each wheel is continuously
sent to the central control ECU. This runs a complex
programme for processing the received information about
the movement of the wheel as well as for calculating
and performing logical operations on 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).
