Abstract: A method for controlling a motor-vehicle lighting device is provided that uses LEDs supplied with PWM signals temporally spaced apart from one another by a first time phase t1 and a second time phase t2. An interval of interest is defined in which an electromagnetic disturbance must not exceed a maximum threshold value ?max; driving signals are supplied on the basis of first phases t1 and t2 computed; and the measured or simulated waveform of the electromagnetic disturbance deriving from the phases t1 and t2 is compared with the maximum threshold value within the interval of interest defined. Where the waveform of the disturbance exceeds the threshold, two phases t1 and t2, once again different from one another, are recalculated; otherwise, the last phases t1 and t2 calculated are selected and used in the PWM control. An advantageous motor-vehicle lighting device is also provided.
