WIPO Patent Application WO/2019/155536
Kind Code:
This vehicle drive device (1) is provided with: a power generator (11) that outputs AC power by being driven and rotated by an internal combustion engine (2); a converter (12) for converting the AC power to DC power and outputting the DC power; and an inverter (14) for converting the DC power to AC power and outputting the AC power. The vehicle drive device (1) is further provided with: an electric motor (15) driven and rotated by means of the AC power output by the inverter (14); and an inverter control unit (16) for calculating a control command value in accordance with an operation command and controlling the inverter (14) on the basis of the control command value. A value obtained by dividing an amount of change in the control command value when the operation command has been increased by the time from when the operation command was changed to when the control command value reaches a control command value corresponding to the operation command after the change has a negative correlation with the rotational speed of the electric motor (15) at a time point when the operation command was changed.
