Device for automatic cleaning of head light of motor vehicle e.g. passenger car, has sensor unit for producing signal based on light distribution, and evaluation unit for activating cleaning unit for headlight based on signal

摘要

The device has a sensor unit (20) e.g. camera, for detecting a light distribution (16) that is generated from a headlight (12) on an object (15) present outside a motor vehicle. The sensor unit is formed for producing a signal based on the light distribution, where the produced signal is supplied to an evaluation unit. The evaluation unit is designed for activating a cleaning unit based on the signal, where the cleaning unit is provided for the headlight. A sensor (21) is provided for detecting environmental parameters e.g. environmental light intensity.
