CA 2402406

A system and method of automatically controlling exterior vehicle lights includes an image sensor (201) and a controller (1105) to generate control signals. The control signals are derived based on information obtained from the image sensor as well as other detected parameters pertaining to the detected light source(s), the vehicle having the inventive control system, and the ambient environment. The control circuit may simply turn certain exterior lights on or off, or change the brightness, aim, focus, etc. to produce various beam patterns that maximize the illuminated area in front of the vehicle without causing excessive glare in the eyes of other drivers.

Un système et un procédé permettant de commander automatiquement les lumières extérieures d'un véhicule comprennent un capteur d'images (201) et une unité de commande (1105) qui génère des signaux de commande. Les signaux de commande sont dérivés des informations produites par le capteur d'images ainsi que d'autres paramètres détectés relatifs à la source ou aux sources de lumières détectées, le véhicule comprenant le système de commande selon l'invention, et l'environnement ambiant. Le circuit de commande peut agir simplement sur certaines lumières extérieures pour les allumer ou les éteindre ou encore pour changer la luminosité, l'orientation, la mise au point et autres afin de produire diverses configurations de faisceaux qui augmentent au maximum la zone éclairée à l'avant du véhicule sans provoquer un éblouissement excessif pour les yeux des autres conducteurs.
