A method of reducing resonance phenomena in a transmission train (6) of an internal combustion engine (2) of a vehicle (1); when the rotation speed (N) of at least part of the transmission train (6) is such that the frequency of a disturbance harmonic component (C4) of the drive torque (T) lies in the neighbourhood of a resonance frequency (Fr) of the transmission train (6), the standard control mode of the cylinders (5) is modified to modify the pattern of the drive torque (T) as a function of the engine angle ( alpha ), and so modify the distribution of the harmonic components (C) of the drive torque (T) to reduce the amplitude of the disturbance harmonic component (C4). <IMAGE> |
