Abstract

A driver assistance system is disclosed which automatically control the high and low beam of a headlamp on a vehicle. The system includes a camera and an image evaluation unit configured to search images acquired by the camera for initial bright zones that correspond with an activated vehicle headlamp, and to switch the headlamp from a high beam to a low beam upon detecting both a first bright zone and a second bright zone that is larger and less bright than the image of the activated vehicle headlamp.
