Title:
METHOD FOR CONTROLLING DIRECTIONAL LIGHTING AND LIGHTING DEVICE IMPLEMENTING THIS METHOD
Document Type and Number:
WIPO Patent Application WO/2023/111309
Kind Code:
A1
Abstract:
The invention relates to a method (100) for controlling directional lighting generated by a vehicle lighting device that emits a light flux that varies depending on the movement of the vehicle, the method comprising the following operations: - a) determining (110) at least three initial light-flux images (Im1, Im2, Im3), each initial light-flux image corresponding to an emission of light by the lighting device in a predefined direction, - d) when the vehicle is not following one of the predefined directions, determining an intermediate light-flux image (Im4) to be emitted by the lighting device in an intermediate direction, by taking a weighted average (170) of two of the three initial light-flux images (Im1, Im2, Im3) corresponding to the directions immediately flanking the intermediate direction; and - e) projecting (130, 180), onto the road scene, depending on the direction of movement of the vehicle, the initial or intermediate light-flux image.
