Method for controlling a rotary electrical machine in order to compensate for the torque oscillations of a traction chain of a motor vehicle

Abstract

The invention mainly relates to a method for controlling a rotating electrical machine (21) of a motor vehicle, the motor vehicle comprising a thermal drive chain (10) comprising a heat engine (11) connected to a gearbox (12) by means of a clutch (13), said electrical machine being integrated in the thermal drive chain or in a drive chain independent of the heat engine, characterised in that, when the clutch (13) is open and the rotating electrical machine (21) operates in motor mode in order to ensure the electrical operation of the motor vehicle, said method comprises:—a step of generating a setpoint torque (Tcons) corresponding to a desire of the driver to accelerate;—a step of determining a pulsed compensation torque (Tcomp) for torque oscillations (Tosc) generated by the drive chain (10);—a step of combining the setpoint torque (Tcons) and the previously determined pulsed compensation torque (Tcomp) in order to obtain a resulting modified setpoint torque (Tcons′); and—a step of applying the resulting modified setpoint torque (Tcons′) to the rotating electrical machine (21).
