Abstract: A method for managing image data in a vehicle lighting system, the lighting system including a lighting module and a multiplexed bus for transmitting compressed image data to the lighting module. The method includes receiving an instruction to trigger a lighting function, the lighting function being configured to be generated by the lighting module from compressed image data corresponding to lighting patterns having L rows, L being an integer. Determining the image data to be compressed from among the image data of the lighting patterns of the at least one lighting function by selecting the image data of X rows from the L rows of the lighting patterns, X being an integer smaller than L. Compressing the image data determined as having to be compressed. Transmitting the compressed image data to the lighting module via the multiplexed bus in order for the lighting function to be generated and projected.

Abstract: A method for controlling a light pattern provided by an automotive lighting device of an automotive vehicle. The method includes providing a road profile, extracting road features from the road profile, dividing the matrix arrangement in row groups, assigning a different shifting value for each row group, each shifting value depending on the road features and dividing each row group in at least a first portion and a second portion. Each portion includes at least a boundary pixel which is in contact with the boundary pixel of an adjacent portion. The method further includes modifying the width of the first portion and the width of the second portion by shifting the position of the boundary pixels in each row group according to the corresponding shifting value and interpolating the luminous intensity values of the pixels belonging to the first and second portion.

Abstract: An illumination system of a motor vehicle includes a first lighting module that is able to emit a first light beam with an upper cut-off, a second lighting module that is able to emit a second, pixelated light beam, and a system for mechanically adjusting the vertical orientation of the first and second light beams. A controller is able to receive an emission instruction for a given lighting function and is designed to control the adjusting system in order to bring about a simultaneous modification of the vertical orientation of the first and second light beams on the basis of the instruction and to control the second lighting module to emit a second, pixelated light beam having predetermined characteristics on the basis of said instruction.
