Abstract

Un appareil photo (12), dirigé vers un visage, représente le visage d'un conducteur de véhicule, et une unité centrale (25) reconnaît le visage du conducteur et détermine la direction du visage. L'unité centrale (25) commande une section de commande de lumière (18) de façon à réaliser un éclairage par une lumière déviée (17-1 à 17-4) en association avec la direction du visage du conducteur. L'unité centrale (25) acquiert des informations de position sur un croisement doté d'un feu de circulation, des informations sur la position actuelle du véhicule, des informations sur une vitesse de véhicule, des informations sur le freinage et des informations sur une position du levier de vitesse à partir respectivement d'une base de données cartographiques (19), d'un récepteur GPS (16), d'un capteur de vitesse de véhicule (13), d'un interrupteur de freinage (14) et d'un capteur de levier (15). Lorsque l'unité centrale (25) détermine, sur la base de ces informations, que le véhicule est arrêté près du croisement doté du feu de circulation, l'unité centrale (25) décide d'interdire l'éclairage par la lumière déviée (17-1 à 17-4) et envoie un signal pour interdire d'allumer la lumière à une section de commande de lumière (18).
