ABSTRACT:
A controller performs processing for calculating a main torque control value, processing for outputting a final control torque value based on the main torque control value and a vibration-suppression torque control value for mitigating torque fluctuation that occurs when a rotating electric machine is operated at the main torque control value, and processing for calculating the vibration-suppression torque control value. The processing for calculating the vibration-suppression torque control value includes processing for calculating an original control value serving as a source of the vibration-suppression torque control value, processing for performing guard processing for restricting the original control value by using a vibration suppression guard value, and processing for smoothing an angular portion where rate of change is discontinuous, that is generated in the torque control value that has been subjected to the guard processing.
