Collision warning with

braking function*

The concept

The system issues a two-phase warning of a
danger of collision at speeds above approx.
10 mph/15 km/h.
The collision warning is available even if cruise
control has been deactivated.
It responds to stationary or moving objects that
are within the detection range of the radar sys‐
tem.

When the vehicle is intentionally brought into
contact with an object, the collision warning is
delayed to avoid false warnings.

Warning stages

Prewarning

This warning is issued, for example, when there
is the impending danger of a collision or the dis‐
tance to the vehicle ahead is too small.

Acute warning with braking function

Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The acute warning prompts the driver to inter‐
vene and, if there is the danger of a collision, is
accompanied by a braking intervention.
The braking intervention is executed with lim‐
ited braking force and for a brief period only. The
intervention cannot bring the vehicle to a com‐
plete standstill.
The braking intervention is executed only if
