    Abstract: The invention provides 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, dividing each row group in a first portion and a second portion, shifting the operation of the first portion of each row group of light sources according to the corresponding shifting value and create a third portion between the shifted first portion and the second portion of each row group.

    Abstract: A method for correcting a first light pattern provided by a lighting device with a matrix of light sources. The method includes steps of providing some resolution data of the light sources, simulating a test map of the light pattern using the resolution data, and simulating distortion maps of the test map. Each distortion map is associated to a distortion factor. Also included is obtaining a real distorted light pattern, comparing the real distorted light pattern with the distortion maps, finding a distortion map which is the most similar to the real distorted map and applying a correction factor to correct the real distorted light pattern, thus obtaining a corrected light pattern. The correction factor is related to the distortion factor of the distortion map which is the most similar to the real distorted map.

    Abstract: A method for correcting a light pattern provided by a first lighting device and a second lighting device. The first lighting device projects a first light pattern and the second lighting device projects a second light pattern. There is an overlapping zone between the first light pattern and the second light pattern. The method includes the steps of, for each lighting device, dividing the light sources in groups, each group being associated to a projection distance, calculating an overlapping region as a function of the projection distance, calculating a number of affected light sources for each group as a function of a representative dimension of the overlapping region and attenuate the intensity of the light emitted by the affected light sources in each group of each lighting device, following a monotonic attenuation pattern from 100% attenuation in the first affected light source to 0% in the last affected light source. The invention also provides an automotive lighting device assembly with control means to perform the steps of this method.

    Abstract: The invention is related to a method for controlling a light pattern provided by an automotive lighting device of an automotive vehicle, wherein a dynamic portion of the light pattern is provided at least by a matrix arrangement of light sources. This method includes the steps of sensing a turn in a steering system of the automotive vehicle, dividing the dynamic portion in a first portion and a second portion, shifting the operation of the light sources associated to the first portion in the same direction as the sensed turn and create a third portion between the shifted first portion and the second portion. The invention also provides an automotive lighting device with control means to perform the steps of the method.
