Abstract (en)
[origin: WO2013092755A1] The invention relates to an inverter for driving an electric motor installed in a road vehicle, said inverter comprising: at least one sensor for measuring a voltage and current within the inverter; storage means for recording the values measured during one mechanical revolution of the electric motor; means for calculating, following the electric motor revolution, a mean electrical power on the basis of the recorded values and current electrical powers; means for calculating the mean value of a difference based on the current electrical powers and the mean electrical power; and means for correcting the torque inversion in the event the value of the difference is greater than a predetermined threshold.
