METHOD FOR CONTROLLING A LIGHT PATTERN AND AUTOMOTIVE LIGHTING DEVICE

The invention is related to a method for managing a light pattern and an automotive lighting device (). The method comprises the steps of projecting an original light pattern, providing a reach distance between a retroreflective object () and the automotive lighting device, estimating a reach time before the automotive lighting device reaches the retroreflective object () 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 () 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.
