Abstract

L’invention concerne un procédé de contrôle d’un dispositif lumineux d’un véhicule automobile comprenant une unité de calcul et un module lumineux comportant une pluralité de sources lumineuses et un contrôleur , le procédé comportant les étapes suivantes : l’unité de calcul génère une image numérique destinée à contrôler le module lumineux pour l’émission d’un faisceau lumineux pixélisé, chaque pixel de l’image numérique présentant une valeur correspondant à une intensité lumineuse d’un pixel du faisceau lumineux pixélisé à émettre par le module lumineux, la correspondance entre les intensités lumineuses des pixels du faisceau lumineux à émettre et les valeurs des pixels de l’image numérique étant réalisée selon une fonction de correspondance non affine ; l’unité de calcul transmet l’image numérique générée au contrôleur; le contrôleur contrôle chacune des sources lumineuses au moyen de l’image numérique reçue pour l’émission du faisceau lumineux pixélisé. Figure à publier avec l’abrégé : Fig. 1The invention relates to a method for controlling a light device of a motor vehicle comprising a calculation unit and a light module comprising a plurality of light sources and a controller, the method comprising the following steps: the calculation unit generates a digital image intended to control the light module for the emission of a pixelated light beam, each pixel of the digital image having a value corresponding to a light intensity of a pixel of the pixelated light beam to be emitted by the light module, the correspondence between the luminous intensities of the pixels of the light beam to be emitted and the values of the pixels of the digital image being carried out according to a non-affine correspondence function; the calculation unit transmits the generated digital image to the controller; the controller controls each of the light sources by means of the digital image received for the emission of the pixelated light beam. Figure to be published with abstract: Fig. 1
