Abstract
(EN)
In a control system (14), an OF calculating means (58) calculates the OF of an object existing in front of a vehicle as a light emitter or a light reflector from the brightness information of an acquired pick-up image in front of the vehicle.  An object attribute determining means (60) determines the attribute of the object according to the OF.  A light distribution control ECU (34) controls the light distribution of headlamp units (12R, 12L) provided in the vehicle according to the attribute of the object.  An image analysis means (50) estimates the shape of the road in front of the vehicle.  The object attribute determining means (60) determines the attribute of the object according to the OF of the object and the shape of the road.

Dans un système de commande (14), un moyen de calcul d’OF (58) calcule l’OF d’un objet existant devant un véhicule en tant qu’émetteur de lumière ou réflecteur de lumière à partir d’informations de luminosité d’une image de capture acquise devant le véhicule. Un moyen de détermination d’attribut d’objet (60) détermine l’attribut de l’objet en fonction de l’OF. Une ECU de commande de répartition de lumière (34) commande la répartition de lumière d’unités phares (12R, 12L) situées dans le véhicule en fonction de l’attribut de l’objet. Un moyen d’analyse d’image (50) évalue la forme de la route devant le véhicule. Le moyen de détermination d’attribut d’objet (60) détermine l’attribut de l’objet en fonction de l’OF de l’objet et de la forme de la route.
