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: The invention relates to a method for controlling a luminous device of a motor vehicle arranged to emit a pixelated light beam in a preset emission region. The method includes receiving an instruction to emit a desired pixelated luminous function for each of the luminous modules. The instruction for creating a digital image forming one segment of the desired pixelated luminous function in a frame corresponding to the preset emission region of the luminous module, the digital image being independent of the types of light sources and of optical device of the luminous module. The method further correcting said created digital image depending on the types of light sources and of optical device of the luminous module. The method additionally emitting, with the luminous module, into the preset emission region, a pixelated light beam corresponding to the corrected digital image.

Abstract: Method for controlling modules for projecting pixelated light beams of a host vehicle. The host vehicle includes a step of determining, using a control device and according to the collected data, a polynomial function which models the profile of the edge and the centre of the road, such that the road profile is modelled based on a polynomial function, the degree of which depends on the curvature of the road. Also included is a step of determining, by means of the control device, a starting point (Pd) and an arrival point (Pa) of an area for projection (ZPd, ZPg, ZP) of patterns, and a step of determining, by means of the control device, a distance (De) between an axis (Ac) of a data/image acquisition means and the patterns, respectively for a right projection area ZPd and a left projection area ZPg. The control device is used to determine the width (Lm) of the pattern.
