Collision warning system* - detection
of cyclists
WARNING
The collision warning system does not
engage in all driving situations or traffic,
weather or road conditions. The collision
warning system does not react to vehicles
or cyclists driving in another direction to
the car or to animals.
Optimal performance of the system requires
that the system function that detects a cyclist
receives as unambiguous information as pos-
sible about the body and bicycle contours -
this implies the opportunity to identify the
bicycle, head, arms, shoulders, legs, upper
and lower body combined with a normal
human pattern of movement.
Warning only activated in the event of a
high risk for collision. This section "Func-
tion" and the section "Limitations" inform
about limitations that the driver must be
aware of before using the Collision Warn-
ing system with Auto Brake.
If large parts of the cyclist's body or bicycle
are not visible to the function's camera then
the system cannot detect a cyclist.
Warnings and brake interventions for
pedestrians and cyclists are deactivated at
vehicle speeds above 80 km/h (50 mph).
For the function to be able to detect a
cyclist, he/she must be an adult and rid-
ing an "adult bicycle".
•
The function only "sees" cyclists from behind,
who are travelling in the same direction.
Warnings and brake interventions for
pedestrians and cyclists do not work in
darkness and tunnels - not even when
streetlights are lit.
The bicycle must be equipped with a
•
highly visible and approved21 rearward-
facing red reflector, fitted at least 70 cm
above the roadway.
The auto-brake function can prevent a col-
lision or reduce collision speed. To ensure
full brake performance, the driver should
always depress the brake pedal - even
when the car auto-brakes.
The function can only detect cyclists
•
directly from behind and who are travel-
ling in the same direction - not at an
angle from behind, not from the side.
Never wait for a collision warning. The
driver is always responsible that the cor-
rect distance and speed are maintained -
even when the collision warning system
with auto-brake is used.
Cyclists travelling on the left or right-hand
edge of the car's imagined/extended side
lines may be detected late or not at all.

The function's capacity to detect cyclists
at dusk and dawn is limited - just like the
human eye.

The reflector must fulfil the recommendations and conditions of the traffic authority in the market in question.
