System for controlling the in situ orientation of a vehicle headlamp, and method of use

Abstract

The invention relates to a system for controlling the in situ orientation of a vehicle headlamp equipped with a light source that is fixed to a mobile reflector and with a camera that is fixed to the mobile reflector and connected to an image processing unit. The invention also relates to a method of controlling the in situ orientation of a vehicle headlamp, comprising the following operations: recording of images of a road scene in front of the vehicle, processing of at least one image of the road scene, determination, from said processed image, of a measured horizon line of the road scene, comparison of this measured horizon line with a predetermined setpoint horizon line and determination of a distance between the measured horizon line and the setpoint horizon line, adjustment of the orientation of the headlamp so that the distance between the measured horizon line and the setpoint horizon line tends towards zero.
