Abstract

L’invention a pour objet un procédé de contrôle d’un dispositif lumineux (1) d’un véhicule automobile comprenant au moins des premier et deuxième modules lumineux (3, 4) agencés pour émettre respectivement des premier et deuxième faisceaux lumineux pixélisés (HD, LD) dans des première et deuxième zones d’émission prédéterminées (ZHD, ZLD) qui leurs sont associées, la résolution du premier faisceau lumineux pixélisé étant supérieure à la résolution du deuxième faisceau lumineux pixélisé et les première et deuxième zones d’émission prédéterminées étant adjacentes, le procédé comportant les étapes suivantes : (E1) Détection de la présence d’un objet cible (C) dans une zone donnée parmi les première et deuxième zones d’émission prédéterminées ; (E2) Formation d’une zone sombre (ZS) dans le faisceau lumineux pixélisé associé à ladite zone donnée, par extinction ou atténuation d’au moins un pixel (HDi,j) dudit faisceau lumineux pixélisé, située au niveau de l’objet cible; (E3, E4) Modification progressive d’au moins un premier pixel (LD1) du deuxième faisceau lumineux pixélisé lorsque l’objet cible se déplace de ladite zone donnée vers l’autre zone des première et deuxième zones d’émission prédéterminée et avant que l’objet cible atteigne l’autre zone.
