F01 KAFAS
Evaluation of Image Data
The various dots, colors and intensities of light captured by the camera are evaluated by
the control unit and, based on the control unit’s assessment, a switch-on or switch-off
recommendation is sent from the KAFAS control unit to the footwell module.
In addition to the switch-on/switch-off recommendation, road speed is also taken into
account.
At speeds below 24mph, the FLA is switched off; at speeds higher than 31mph, it may
be switched on, depending on all other parameters.
If the vehicle is in an environment with adequate light, the high-beam headlights do not
switch on. The KAFAS control unit sends a switch-off recommendation to the footwell
module.
These conditions could be:
• Daylight
• Twilight
• Road lighting
• Illuminated places
The system is designed to switch off the high-beam headlights automatically in response
to the following conditions.
• Oncoming traffic
• Preceding traffic
• Detection of background brightness
(twilight, street lamps, illuminated places, etc.)
• Driving speed too low
