Abstract

A control device for a headlight for emitting light according to a headlight signal corresponding to an adjustable light distribution. The control device outputs the headlight signal, corresponding to the adjustable light distribution, to the headlight. The control device has an evaluation unit that determines object position data of the object when particles are detected using a detection unit and a self-illuminating object is detected, and to determine, as a function of the object position data, a region in which the object is located. The evaluation unit also generates data for the light distribution as a function of the region in such a way that a light intensity in the region is reduced or increased with respect to a light intensity outside this region, and correspondingly to determine and output the headlight signal from the data for the light distribution.
