Abstract
A control device configured with an external input estimator that reduces a vibration component of a rotational speed of the power transfer system at a rotational speed of the rotary electric machine and estimates transfer system input torque on the basis of the rotational speed of the rotary electric machine, and that estimates external input torque by subtracting at least output torque of the rotary electric machine from the transfer system input torque. A low-vibration speed calculator calculates a low-vibration rotational speed on the basis of the external input torque and vehicle required torque. A rotational speed controller calculates feedback command torque that matches the rotational speed of the rotary electric machine with the low-vibration rotational speed. A torque command value calculator calculates an output torque command value on the basis of the vehicle required torque and the feedback command torque.
