Abstract (en)

[origin: WO2021122071A1] Disclosed is a method for controlling a lighting system (3) of a host motor vehicle (1) comprising a plurality of selectively controllable elementary light sources (32ij) each able to emit an elementary light beam (HDij), the vertical angular opening of which is less than 1°, the method comprising the following steps: (E1) Detection of a target object (5) by a sensor system (2); (E2) Determination of a vertical angle (a) between a given point (21) of the sensor system of the host vehicle and a detected point (51) of the target object; (E5) Determination, from the vertical angle, of a lower angle (Vinf) and an upper angle (Vsup) between a given point (31) of the lighting system and, respectively, an upper cut-off and a lower cut-off intended to together vertically border the target object; (E6) Control of the elementary light sources (32ij) to emit a pixelated road light beam (HD), some of the elementary light sources being controlled, as a function of the lower and upper angles, to generate, in the light beam, a dark area (Zc) extending substantially between the upper and lower cut-offs.
