Abstract

Procédé de commande d’un système d’éclairage d’un véhicule automobile hôte comprenant une pluralité de sources lumineuses élémentaires contrôlables sélectivement et chacune apte à émettre un faisceau lumineux élémentaire dont l’ouverture angulaire verticale est inférieure à 1°, le procédé comportant les étapes suivantes : Détection d’un objet cible par un système de capteur ; Détermination d’un angle vertical entre le système de capteur du véhicule hôte et l’objet cible ; Détermination, à partir dudit angle vertical, d’un angle inférieur et d’un angle supérieur entre le système d’éclairage et respectivement une coupure haute et une coupure basse destinées à border ensemble verticalement l’objet cible ; Contrôle des sources lumineuses élémentaires pour émettre un faisceau lumineux pixélisé de type route, une partie des sources lumineuses élémentaires étant contrôlées, en fonction desdits angles inférieur et supérieur, pour générer dans le faisceau lumineux une zone sombre s’étendant sensiblement entre lesdites coupures haute et basse. Figure à publier avec l’abrégé : Fig. 3
