Setting device for headlamp light beam has processor with monitor that evaluates information content of image from sensor, prevents further processing if information insufficient

摘要

The device has an adjuster (20), at least one optoelectronic sensor (26) for detecting light emitted by the headlamp and reflected from the road and a processor (34,50,60) for evaluating an image (30) of the illumination system provided by the sensor(s) and correcting any error via the adjuster. The processor has a monitor (34) that evaluates the information content of the image and prevents further processing if there is insufficient information.
