Abstract:
An electronic control unit controls an inverter by pulse width modulation control. The electronic control unit performs first control of setting voltage commands of a d axis and a q axis based on a torque command for a motor and a detected electrical angle of the motor which is detected by a detection unit at intervals of one cycle of a carrier wave. The electronic control unit performs second control including control of calculating a predicted electrical angle at intervals of a half cycle of the carrier wave.

Claim (Index 1):
A drive device comprising:\n a motor; an inverter configured to drive the motor by switching a plurality of switching elements; and an electronic control unit being configured to detect an electrical angle of the motor as a detected electrical angle,\n the electronic control unit being configured to control the inverter by pulse width modulation control, \n the electronic control unit being configured to perform first control at intervals of one cycle of a carrier wave, the first control being control of setting voltage commands of a d axis and a q axis based on a torque command for the motor and the detected electrical angle, and \n the electronic control unit being configured to perform second control at intervals of a half cycle of the carrier wave, the second control being control including control of calculating a predicted electrical angle based on the detected electrical angle, the predicted electrical angle being used to generate a pulse width modulation signal.
