Abstract

L'invention est relative à un procédé de gestion d'un motif lumineux et d'un dispositif d'éclairage automobile (10). Le procédé comprend les étapes consistant à projeter un motif lumineux original, à fournir une distance d’atteinte entre un objet rétroréfléchissant (4, 5) et le dispositif d'éclairage automobile, à estimer un temps d’atteinte avant que le dispositif d'éclairage automobile n'atteigne l'objet rétroréfléchissant (4, 5) et à utiliser le temps d’atteinte pour décider s'il faut activer une fonctionnalité de gestion du motif lumineux. Si la fonctionnalité de gestion des motifs lumineux est activée, utiliser une image fournie par un capteur d'image (1) en temps réel pour décider de l'emplacement d'un masque. Si la fonctionnalité de gestion du motif lumineux est activée, calculer un motif lumineux optimal pour le masque et modifier le motif lumineux original, y compris le masque avec le motif lumineux optimal.Figure pour l'abrégé : figure 1
