Title
(EN) METHOD FOR CONTROLLING A ROTATING ELECTRICAL MACHINE FOR COMPENSATING FOR TORQUE OSCILLATIONS OF A DRIVE CHAIN OF A MOTOR VEHICLE
(FR) PROCÉDÉ DE PILOTAGE D'UNE MACHINE ELECTRIQUE TOURNANTE POUR COMPENSER DES OSCILLATIONS DE COUPLE D'UNE CHAÎNE DE TRACTION DE VÉHICULE AUTOMOBILE
Abstract
(EN)
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).
