Control device
First Claim
1. A control device that controls a rotary electric machine that is provided in a power transfer system from a drive force source for a vehicle to wheels and serves as the drive force source, the control device comprising:
- 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, which is torque input to the power transfer system, on the basis of the rotational speed of the rotary electric machine, and that estimates external input torque, which is input from the wheels to the power transfer system, by subtracting at least output torque of the rotary electric machine from the transfer system input torque;
a low-vibration speed calculator that calculates a low-vibration rotational speed, which is a rotational speed obtained by reducing a vibration component produced in the rotational speed of the rotary electric machine, on the basis of the external input torque and vehicle required torque, which is torque required to drive the wheels;
a rotational speed controller that calculates feedback command torque that matches the rotational speed of the rotary electric machine with the low-vibration rotational speed; and
a torque command value calculator that calculates an output torque command value, which is a command value of the output torque of the rotary electric machine, on the basis of the vehicle required torque and the feedback command torque.

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.
