Abstract

L'invention fournit une méthode pour projeter un motif lumineux (2) dans l'habitacle d'un véhicule automobile (10). Le procédé comprend les étapes consistant à fournir un projecteur de lumière (1) capable de projeter un motif lumineux (2) sur une surface totale (3), à émettre un motif lumineux (2) qui s'étend sur un maximum de 90% de la surface totale (3), à détecter un mouvement du projecteur de lumière (1) et à déplacer le motif lumineux (2) pour compenser le mouvement du projecteur de lumière. L'invention fournit également un ensemble de projection automobile avec des moyens de contrôle pour accomplir les étapes d'une telle méthode.Figure pour l'abrégé : figure 2The invention provides a method for projecting a light pattern (2) into the passenger compartment of a motor vehicle (10). The method comprises the steps of providing a light projector (1) capable of projecting a light pattern (2) over a total surface (3), emitting a light pattern (2) which extends over a maximum of 90% of the total surface (3), detecting a movement of the light projector (1) and moving the light pattern (2) to compensate for the movement of the light projector. The invention also provides an automotive projection assembly with control means for performing the steps of such a method. Figure for the abstract: figure 2
