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
