F01 KAFAS
Control of the High-beam Headlights
At the request of the FLA (KAFAS) control unit, the actual switching on and off of the
high-beam headlights is always carried out by the footwell module, which is responsible
for all of the exterior lighting.
The FLA control unit uses its own image data to assess background brightness.
The decision of the FRM to activate the dipped-beam headlights in A mode is made in
the FRM independently of the FLA function. The FRM receives the light signal from the
RLSS.
System limitations
In various situations, and under specific environmental conditions, the limitations of a
camera-based system begin to impact on functionality.
These limitations may be reached in the following situations.
• Extremely bad weather conditions (e.g. fog or heavy snowfall).
• Poorly illuminated road users (e.g. riders on small motorcycles, cyclists, pedestrians).
• Individual driving situations (e.g. sharp bends, steep hills, traffic coming at right
angles from left or right).
• Differentiation between different light sources, reflective traffic signs, etc.
• No recognition of oncoming traffic is possible if only the cone of light is within the
video camera’s field of view.
• Recognition is possible only if the light source itself is within the field of view of the
video camera.
The driver is able to intervene at any time and override the assistance system by switch-
ing the high-beam headlights on and off manually.
The driver always bears sole responsibility for the vehicle and the control of the vehicle’s
lighting.
