摘要: A control device includes an ECU and an inverter device having power circuitry including an inverter and a motor control unit. A rotation angle sensor detects a rotation angle of a motor. The power circuitry receives a rotation angle of the motor from the rotation angle sensor to perform control in accordance with the rotation angle of the rotor, the control being based on a torque command mapping table in which a relationship between a rotation speed and a torque of the motor is defined. The power circuitry includes an adjustment module adjusting the torque command mapping table with respect to a torque command from the ECU and a speed of the electric vehicle.
