Motor vehicle illumination system provided with a lighting module able to emit a pixellated light beam

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.
