System for controlling an automotive vehicle three-phase electric machine (2) supplied via chopped voltages, comprising a means (3) of determining settings of current of the phases of the electric machine as a function of a torque request from the driver, and a means (4) of regulating able to determine voltages of each phase as a function of corresponding settings of current. The system comprises a means (5) of correcting the torque oscillations, which is able to determine the powers of each phase, to determine whether the speed of rotation of the magnetic field exceeds a threshold value, to carry out a bandpass filtering of the powers, and to determine attenuation currents relating to each phase as a function of the post-filtering powers; subtractors (6,7,8) being able to subtract the attenuation currents relating to each phase from the settings of current of the corresponding phases, destined for the regulating means (4). |
