Method for controlling a motor vehicle lighting system

A method for controlling a lighting system of a host motor vehicle, the lighting system including a plurality of selectively controllable elementary light sources, each elementary light source being able to emit an elementary light beam the vertical opening angle of which is smaller than 10, the method comprising:

• detecting a target object by means of a sensor system of the host vehicle;
• determining a relative distance between a given point of the sensor system of the host vehicle and a detected point of the target object and determining a slope of the road on which the target object is located;
• determining, on the basis of the relative distance and of the slope, a lower angle and an upper angle between a given point of the lighting system of the host vehicle and an upper cut-off and a lower cut-off that are together intended to vertically border the target object;
• controlling the elementary light sources of the lighting system of the host vehicle so as to emit a pixelated high light beam, some of the elementary light sources being controlled, depending on the lower and upper angles, so as to generate, in the high light beam, a dark region extending substantially between the upper and lower cut-offs.
