Abstract: A method for managing image data in a vehicle lighting system that includes a lighting module and a multiplexed bus for transmitting compressed image data to the lighting module. The method includes receiving an instruction to trigger at least one lighting function to be generated by the at least one lighting module. Determining a required data rate level for transmitting the compressed image data over the multiplexed bus. Comparing the determined data rate level with a data rate threshold value of the multiplexed bus. Compressing the image data of the lighting function according to: the first frequency when the determined data rate level is lower than or equal to the data rate threshold value and according to a second frequency selected within the frequency range such that the second frequency is lower than the first frequency when the determined data rate level is greater than the data rate threshold value.

Abstract: A plurality of luminous modules able to emit a segmented light beam to be controlled by a common control processor having a single video output interface, while maintaining the ability to project different outlines with each luminous module. This decreases the number of connections necessary between a control unit and a plurality of luminous modules, thereby decreasing the complexity of the system, and decreasing the production cost thereof.

Abstract: A method for controlling an automotive lighting device. The method includes projecting a first light pattern, capturing an image of a region in front of the lighting device, obtaining a luminance map from the captured image, identifying objects in the luminance map and classify them as reliable or not reliable, according to at least one reliability criterion and modifying the first light pattern to modify the luminous intensity in at least one zone intended to project light on a non-reliable object.

Abstract: The present invention relates to a lighting module for a motor vehicle headlamp module including a light source able to emit light radiation, a processing device able to generate a light flux from said light radiation, and an imaging optical system able to project an exit beam from said light flux. The lighting module includes means for controlling an angular aperture of the exit beam, the angular aperture being chosen from a first aperture and a second aperture, the first aperture corresponding to a wider angle than the second aperture, so that, for a given intensity of the light radiation of the light source, the exit beam corresponding to the second aperture has a higher light intensity than the exit beam corresponding to the first aperture.
