According to the invention, an iterative operation of searching for the optimal value theta opt of the angle of advance is performed, which consists in periodically adding an increment of angle DELTA theta to an instantaneous angle of advance theta 0, in detecting the instantaneous speeds N1t at the end of a half-period without an increment of angle of advance DELTA theta , during the measurement of order t, and the speeds N2(t-1) and N2t at the end of half-periods with an increment DELTA theta during the earlier measurement of order t-1 and during the measurement of order t and in correcting the angle of advance theta 0 by subtracting therefrom or adding thereto a value epsilon theta less than or equal to DELTA theta if 2N1t is greater than or less than N2(t-1) + N2t, whereas no correction is made if these values are equal.
