Abstract
A method for beam range regulation of at least one headlamp of a vehicle includes: reading in a camera image of at least one camera of the vehicle, the camera image including at least a part of a representation of a projection surface of a light cone of the headlamp in front of the vehicle; determining at least one coordinate of at least one predefined brightness transition and/or of a predefined brightness inhomogeneity in the camera image; comparing the coordinate with a target coordinate in order to obtain a difference of the coordinate from the target coordinate, the target coordinate representing a coordinate at which the predefined brightness transition or the predefined brightness inhomogeneity is expected; and controlling the headlamp with a beam range modification signal that is a function of the difference, in order to modify the beam range.
