Night vision assist, function - GF54.30-P-0005SX
MODEL 221.0 /1, 216.3 with CODE (610) Night vision assist up to Model Year 8
Function
With the night view assist system the course of the road is displayed visually in darkness in order to recognize obstacles before they become visible in the conventional headlamp beam.
To this end, the road in front of the vehicle is illuminated by infrared lamps.
Infrared light is invisible to the human eye. Oncoming traffic is thus not dazzled.
The night view assist camera mounted in the area of the overhead control panel control unit is designed for infrared light and records the direction of the road.
During the picture display the electronic speedometer is displayed as a bar graph. The Night View Assist camera recordings are shown in the instrument cluster.
The display corresponds to the view through the windshield when the high beam is switched on. This means that the driver still enjoys a "high beam" visible area.
The infrared lamps are activated depending on the degree of darkness and the speed of the vehicle.
The night view assist camera operates like a conventional camera, but with an increased infrared light spectrum. For this reason a picture is not displayed when the infrared lamps are not activated.
Function requirements
- Circuit 15 ON
- Rain/light sensor detects twilight or night
- Active low beam
- Drive position "R" not engaged
- Vehicle speed above 15 km/h
Function sequence
The night view assist system is activated by pressing the night view assist button.
The request is read in by the upper control panel control unit via the upper control panel LIN and transmitted by the ESP control unit to the night view assist control unit via the central gateway control unit.
After enable by the night view assist control unit the multifunction display in the instrument cluster changes speedometer display and the display appears.
Extremely bright picture areas, which could dazzle the driver, are suppressed and thus the driver is able to perceive the other content in the picture (e.g. obstacles, pedestrians or cyclists). The brightness distribution is processed in the night view assist control unit.
The rain/light sensor detects three brightness levels:
- Day: Night view assist deactivated (no display)
- Twilight: Night view assist partially activated (display only)
- Night: Night view assist system fully activated (display and infrared lamps active)
