Motor vehicle`s lighting equipment controlling method, involves providing sensor units, which deliver signals dependent on radiation from sensor units, and controlling equipment and liquid crystal unit dependent on sensor signals

摘要

The method involves providing radiation-sensitive sensor units (15, 17, 19) of a sensor device as sensor, which delivers signals dependent on the radiation falling from the sensor units. A lighting equipment (24) and a liquid crystal unit (26) are controlled dependent on the signals of the sensor. The liquid crystal unit modifies the transmission capacity of a disc (30) of a motor vehicle. An independent claim is also included for a sensor device for automatic switching of lighting equipment of a motor vehicle.
