Reduction of the variety/number of
components and thus installation
costs for the vehicle manufacturer.
Dispensing with the required air valves
and their adjustment by introducing
electronic control and the simple
setting of parameters this permits.
By using pressure control circuits
which operate with a high degree of
precision, it is possible to almost
completely eliminate the deviations in
characteristics encountered today.

The “electrical brake line” and
electronic control can considerably
improve the time response and thus
contribute towards reducing the
stopping distance and improving the
stability of the tractor-trailer
combination.
Extending the diagnostic features
for the whole of the braking system,
including maintenance and repair
instructions.
Permitting more comprehensive
testing after production with automatic
recording of the test findings.
It was these possible improvements
which provided the basis for the
development of an electronically
controlled EBS on the trailer.
