Method for controlling a light pattern and automotive lighting device

Abstract

The invention is related to a method for managing a light pattern and an automotive lighting device (10). The method comprises the steps of projecting an original light pattern, providing a reach distance between a retroreflective object (4, 5) and the automotive lighting device, estimating a reach time before the automotive lighting device reaches the retroreflective object (4, 5) and using the reach time to decide whether to activate a light pattern management functionality. If the light pattern management functionality is activated, using an image provided by an image sensor (1) in real time to decide the location of a mask. If the light pattern management functionality is activated, calculating an optimum light pattern for the mask and modifying the original light pattern including the mask with the optimum light pattern.
