Abstract

L’invention se rapporte à un procédé d’éclairage pour un véhicule automobile équipé d’un système d’éclairage adaptatif, le procédé comportant les étapes suivantes : - détecter (40), au moyen d’une caméra la présence de véhicules dans une première zone et dans une deuxième zone, les première et deuxième zones étant situées de part et d’autre d’une zone centrale délimitée par un premier et un deuxième plans verticaux, les deux plans verticaux étant sécants entre eux et sécants avec un plan vertical contenant l’axe longitudinal du véhicule ; - si la présence de véhicules est détectée dans la première zone et/ou dans la deuxième zone pendant une durée de détection supérieure à une première valeur seuil, activer (42-44) un mode d’éclairage adapté ; - si la présence de véhicules n’est plus détectée pendant une durée de non-détection supérieure à une deuxième valeur seuil désactiver (46) le mode d’éclairage adapté. Figure pour l’abrégé : Fig. 4The invention relates to a lighting method for a motor vehicle equipped with an adaptive lighting system, the method comprising the following steps: - detecting (40), by means of a camera, the presence of vehicles in a first zone and in a second zone, the first and second zones being situated on either side of a central zone delimited by a first and a second vertical planes, the two vertical planes being intersecting with each other and intersecting with a vertical plane containing the longitudinal axis of the vehicle; - if the presence of vehicles is detected in the first zone and / or in the second zone for a detection time greater than a first threshold value, activate (42-44) a suitable lighting mode; - if the presence of vehicles is no longer detected for a period of non-detection greater than a second threshold value, deactivate (46) the appropriate lighting mode.
