1. 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 able to emit an elementary light beam whose vertical angular aperture is smaller than 1°, the method comprising:
detecting a target object with a sensor system of the host vehicle;
determining, with a controller, a vertical angle between a given point of the sensor system of the host vehicle and a detected point of the target object;
determining, from the vertical angle with the controller, 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 intended to together vertically border the target object; and
controlling the elementary light sources, with an internal controller, of the lighting system of the host motor vehicle to emit a pixelated high light beam, 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 region extending substantially between the upper and lower cut-offs.
