METHOD FOR OPERATING A HIGH-RESOLUTION HEADLAMP OF A VEHICLE

A method for operating a high-resolution headlamp of a vehicle, the headlamp being configured to project an image into the outer region of the vehicle. At least two regions are selected in the image to be projected which have the same brightness gradients. The brightness gradients of the at least two regions are analyzed in the projection to be carried out. If, during the analysis, a difference in the brightness gradients between individual ones of the selected regions is detected in the projection to be carried out, the headlamp is controlled in such a way that the brightness gradients of the selected regions in the projection to be carried out are matched to each other.

Process for controlling a headlamp of a motor vehicle

A process is provided for controlling a headlamp of a motor vehicle. The headlamp includes a first light source module and a second light source module. The light source modules each feature several light sources that emit light. The light emitted by the light sources of the light source module represents a first light distribution, and the light emitted by the light sources of the second light source module represents a second light distribution. The first light distribution and the second light distribution partially overlap. The first light distribution and the second light distribution together form an overall light distribution. A subarea of the overall light distribution is formed only by the first light distribution, and the subarea is a vertical edge area of the overall light distribution.
