Abstract

Système d’éclairage de véhicule avec affichage sur une surface de route Selon l'invention, un système d’éclairage de véhicule comporte un feu de dessin de surface de route (42) configuré pour tracer, sous forme d’un dessin sur une surface de route, des informations prédéterminées en émettant de la lumière vers une cible comprenant un sol, un mur ou analogues autour d’un véhicule (1), un capteur d’éclairement (45) capable de mesurer un éclairement autour du véhicule (1), et une unité de commande de feu (43) configurée pour commander le feu de dessin de surface de route (42). L’unité de commande de feu (43) est configurée pour commander le feu de dessin de surface de route (42) de sorte qu’un éclairement du dessin sur la surface de route doive dépasser l’éclairement mesuré par le capteur d’éclairement (45). Figure pour l’abrégé : Fig. 1A-1B.
