摘要： When an ECU receives a transmission signal having a high level from a transmission, the ECU exerts torque reduction control to reduce a torque control value for a motor generator. Furthermore the ECU sets an optimum (or target) value of a voltage as based on the torque control value and a motor rotation speed and controls an upconverter. Herein, when the transmission is shifting gears, the ECU controls the upconverter to allow the voltage to be constant regardless of whether the torque reduction control is exerted to reduce the torque control value.

摘要： In the rectangular-wave voltage control mode, torque feedback control, in which the voltage phase of the rectangular-wave voltage is adjusted based on the deviation of the torque estimated value from the torque command value, is performed. A torque estimation portion calculates the torque estimated value using the motor currents calculated based on the values detected by a current sensor and a rotational position sensor, as in the case of the PWM control mode. Namely, the same state quantity (quantity detected by the sensors) of the alternating-current motor is used in the motor control in both the rectangular-wave voltage control mode and the PWM control mode.
