VEHICLE DRIVE DEVICE

A vehicle drive device includes a generator to output AC power, a converter that converts the AC power into DC power, and an inverter that converts the DC power into AC power. An electric motor is driven by the AC power output by the inverter, and an inverter controller (i) calculates a control command value in accordance with an operation command and (ii) controls the inverter based on the calculated value. A value obtained by dividing (i) an amount of the change in the control command value in a case of an increase of the operation command by (ii) a period from when the operation command changes to when the control command value reaches the control command value corresponding to post-change operation command has a negative correlation with the rotational speed of the electric motor at the time when the operation command changes.
