MECHANICAL COMPONENT CONTROLS

Emergency brake assistance

37A

Emergency brake assist is a system which supple-
ments ABS.

OPERATING PRINCIPLE

Emergency brake assist enables the system to recogni-
se the situation and act immediately to provide the best
possible stopping distance.

Emergency braking is calculated according how quickly
the brake pedal is fully depressed; in this situation, bra-
king assistance instantaneously reaches maximum
power.

The system works conditionally for current braking sys-
tems.

The emergency brake assist is a mechanical system
built into the brake servo and completely independent
of any electronic component.

The brake servo is fitted with a magnet which reacts by
locking the control unit when the pedal is depressed
sharply.
