Abstract
A method for controlling a lighting system of a motor vehicle including a generator for generating a pulse-width modulated signal having a first peak intensity or a second peak intensity higher than the first peak intensity, and a light source. The method includes reception of an instruction to emit a light beam according to a given target luminous flux, selection of a peak intensity from the first and second peak intensities depending on the given target luminous flux. Also included is determination of a target duty cycle of a pulse-width modulated signal having the selected peak intensity depending on the given target luminous flux and the efficiency of the light source, and generation of a target signal having the selected peak intensity and the determined target duty cycle and provision of the target signal to the light source.
