Image Sensor: Notes

The image sensor below the screen print (black area at upper edge of the windscreen) points forward through the windscreen. The sensor field is 15° to the left and right (see graphic) as well as 5° to the top and bottom.

The center axis of the image sensor must be aligned parallel to the longitudinal axis of the vehicle to ensure the same degree of functional accuracy for each type of vehicle.

Otherwise, restrictions in the sensor field may result in impaired detection of vehicles in bends and less effective differentiation between vehicles and reflections from road signs.

The high beam assistant adapts itself within a tolerance of 3°, thus automatically compensating for slight deviations from the center axis.
