Headlight installation for motor vehicle, has microcontroller controlling installation in degraded control structure based on fault signal produced by detection units when fault in operation of electrical actuators is detected

摘要

The installation has low beam headlights (18, 20) with electrical actuators (34), high beam headlights, and fog lights (26, 28). An electronic control unit has controlled supply devices (46, 48) with fault detection units (62, 64) for producing a fault signal when a fault in operation of the actuators is detected. A microcontroller (58) controls the installation in a degraded control structure based on the signal. An independent claim is also included for a method of controlling a headlight installation for a motor vehicle.
