System Design

Brake Force Distribution
Fig. 3 shows an example of the brake
force distribution on a towing vehicle,
both when it is laden and when it is unladen.
What has been implemented is
what is known as combined distribution
of brake forces.
It permits a combination of optimized
brake force distribution for the applicable
adhesion at higher index deceleration
values and optimized brake force distribution
in terms of lining wear at lower index
deceleration values. If wear sensors have
also been fitted, as in ACTROS, their signals
are evaluated by the EBS and converted
for adaptive lining wear control.
For this purpose, the braking pressure
distribution can be defined for slower
deceleration in such a way that the linings
on the front and rear wheels can be
changed at the same times. Deceleration
optimized for the applicable adhesion
values in the higher braking range results
in the approximately simultaneous response
of ABS control on all axles.
Improved
ABS and ASR Control
The functions of both ABS and ASR
have been integrated in EBS, and further
enhancements have been achieved in
terms of control performance and improved
comfort by means of additional
information on actuation of the brake,
index value, axle load and braking
pressure.
