Distance warning function

Distance warning function
The distance warning function driver assistance system pro-
vides a static and dynamic distance warning in certain situ-
ations. In technical terms, the system consists of a distance
warning controller unit with radar sensor and the distance
warning function gateway.
Static distance warning
A visual warning (warning lamp on instrument cluster) is trig-
gered as soon as a vehicle is detected in front and a certain
time gap between the vehicle in front is dropped below i.e.
the following distance is too short. The static distance war-
ning only operates for moving objects as of a systems vehicle
speed of 30 km/h.

Dynamic distance warning
A dynamic distance warning is triggered if the systems ve-
hicle approaches a detected vehicle in front at high speed
or high acceleration relative to the vehicle in front. In this
case, both a visual and an acoustic warning are issued. The
dynamic distance warning only operates for moving/stopping
objects at a maximum speed of 7 km/h and for stationary
objects up to 70 km/h.
Customer benefits
The aim of the distance warning function is to inform an inat-
tentive driver that there is a risk of a rear-end collision.
