Abstract

An arrangement for visualizing the illumination by at least one vehicle headlight of a zone situated in front of the vehicle as considered in the forward driving direction includes a camera mounted on the vehicle and operative for taking a succession of scenes of the environment of the vehicle including the aforementioned zone as the vehicle travels on a roadway in the forward driving direction. A visualization device including a monitor visually renders the scenes obtained from the camera, and a simulated rendition of the region illuminated by the headlight is presented in the succession of scenes appearing on the monitor. The light beam issued by the headlight is presented in a simplification as a light cone. The roadway in front of the vehicle, its edges of the roadway, respective marking lines in the scenes representative of distances in at least one of the direction of travel of the vehicle and transversely thereto, a marker for indicating the instantaneous direction of travel of the vehicle and/or the area of intersection of the simulated light beam with roadway in front of the vehicle, its edges and/or its center are presented on the monitor in an especially emphasized manne…
