Abstract

A method for adjusting the lighting range of a headlamp in a motor vehicle, is performed with the following steps. A first coordinateis acquired that corresponds to a position of the motor vehicle. At least one image of a camera connected with the motor vehicle is evaluated so as to acquire a second coordinate that corresponds to the position of an object on a roadway in the zone ahead of the motor vehicle. A reference angle is calculated for the motor vehicle from the first coordinate, the second coordinate and a height of the camera over the roadway. The lighting range of the headlamp is adjusted based on the reference angle.
