Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur Ansteuerung mindestens eines Lichtmoduls (2) einer Leuchteinheit eines Fahrzeugs, mit einer Lichtsteuerung (4) und einer Umfelderfassungseinrichtung (6), wobei das Frontumfeld (8) des Fahrzeugs in Abhängigkeit eines als relevant eingestuften Objekts (10) mittels der Lichtsteuerung (4) und dem Lichtmodul (2) beleuchtet wird. Um eine alternative technische Lösung zur Verbesserung der Sichtbarkeit von in einem Frontumfeld (8) eines Fahrzeugs erfassten und als relevant eingestuften Objekten (10) anzugeben, wird vorgeschlagen, dass die Leuchteinheit eine Leuchtdichteerfassungseinrichtung (12) zur Erfassung der Leuchtdichten des erfassten und als relevant eingestuften Objekts (10) in dem Frontumfeld (8) des Fahrzeugs und einer dieses Objekt (10) umgebenden Objektumgebung (8.1) des Frontumfelds (8) aufweist und das Frontumfeld (8) des Fahrzeugs in Abhängigkeit des Leuchtdichtekontrastes zwischen dem Objekt (10) und der Objektumgebung (8.1) beleuchtet wird. Ferner betrifft die Erfindung eine Leuchteinheit, ein Computerprogrammprodukt und ein computerlesbares Medium.
(EN)
The present invention relates to a method for controlling at least one light module (2) of a light unit of a vehicle, comprising a light controller (4) and a surroundings detection device (6), wherein the vehicle front surrounding area (8) is illuminated by means of the light controller (4) and the light module (2) in accordance with an object (10) classified as relevant. In order to provide an alternative technical solution for improving the visibility of objects (10) detected in the vehicle front surrounding area (8) and classified as relevant, according to the invention: the light unit has a luminance detection device (12) for detecting the luminance of the object (10) detected and classified as relevant in the vehicle front surrounding area (8) and the luminance of the object vicinity (8.1) surrounding said object (10) in the vehicle front surrounding area (8); and the vehicle front surrounding area (8) is illuminated in accordance with the luminance contrast between the object (10) and the object vicinity (8.1). The invention also relates to a light unit, a computer programme product and a computer-readable medium.
(FR)
La présente invention concerne un procédé de commande d'au moins un module d'éclairage (2) d'une unité d'éclairage d'un véhicule, comportant un système de commande d'éclairage (4) et un dispositif de détection d'environnement (6), l'environnement avant (8) du véhicule étant éclairé au moyen du système de commande d'éclairage (4) et du module d'éclairage (2) en fonction d'un objet (10) qui est considéré pertinent. Afin d'indiquer une autre solution technique pour améliorer la visibilité des objets (10) détectés dans un environnement avant (8) d'un véhicule et classés comme pertinents, il est proposé que l'unité d'éclairage comprenne un dispositif de détection de luminance (12) pour détecter la luminance de l'objet détecté (10) classé comme pertinent dans l'environnement frontal (8) du véhicule et un environnement objet (8.1) entourant cet objet (10) de l'environnement frontal (8) et l'environnement avant (8) du véhicule est éclairé en fonction du contraste de luminance entre l'objet (10) et l'environnement objet (8.1). L'invention concerne également une unité d'éclairage, un produit programme informatique et un support lisible par ordinateur.
