Abstract
A method is described for signalling obstacles on a road in the area in front of a motor vehicle, useable in particular when driving at night as an extension of the lighting systems on board the vehicle itself. For this purpose, when the lights of the vehicle 40 are turned on, the presence of obstacles in the zone in front of the vehicle is detected and their distance is calculated 43, the existing conditions of visibility are detected 45, 47, a zone of visibility is determined on the basis of the visibility conditions found 46, 48 and 49, and an alarm signal is generated only when the obstacle detected is outside the zone of visibility 50, 51. <IMAGE>
