摘要： A vehicle includes a converter for stepping up power provided from a power storage device, and an inverter for converting the power output from converter and outputting it to an alternating-current motor for driving the vehicle. In the vehicle, a rectangular voltage control unit controls the inverter by means of rectangular wave voltage control that is based on a torque command value and the like, so as to control an output torque of the alternating-current motor. A system voltage control unit controls a system voltage, which is an output voltage of the converter. The system voltage control unit lifts a restriction on a system voltage command value based on an accelerator pedal position and the like, and then increases it. When increasing the system voltage command value during the rectangular wave voltage control for the inverter, a cooperative control unit increases the system voltage command value and the torque command value in a cooperative manner.

摘要： In a control of an AC motor that uses a PWM control and a rectangular-wave control, when switching is conducted from the rectangular-wave control to the PWM control, a current command generated in a current command generation unit is corrected so as to smooth the variations in a time axis direction on the basis of a target torque command value by taking the final current state in the rectangular-wave control immediately prior to switching as an initial value, thereby generating a current command after the correction. An inverter is current feedback-controlled based on the current command after the correction. As a result, the continuity from the current state immediately prior to switching of the rectangular-wave control can be ensured for the current command in the PWM control.

摘要： An AC electric motor, an inverter and a controller are mounted on an electric powered vehicle. The controller includes a voltage deviation calculating unit, a modulation factor calculating unit, and a mode switching determination unit. The voltage deviation calculating unit calculates a voltage deviation between a first voltage command when the rectangular wave voltage control is executed and a second voltage command when pulse width modulation control is executed, by inputting a current deviation to a voltage equation of the AC electric motor. Modulation factor calculating unit calculates the modulation factor based on the first voltage command and the voltage deviation. The mode switching determination unit determines whether or not control mode of the AC electric motor from the rectangular wave voltage control to the pulse width modulation control is necessary, based on the modulation factor.

摘要： In the hybrid vehicle, a boost converter is controlled to make a post-boost voltage or a voltage on the side of an inverter become a target post-boost voltage corresponding to a target operation point of a motor in accordance with a target post-boost voltage setting map that divides an operation region of the motor into a non-boost region and a boost region when a operation point of the motor is included in the boost region. The target post-boost voltage setting map is prepared so that the non-boost region includes a region in which a loss produced by driving the motor when not boosting the post-boost voltages becomes smaller than the loss produced when boosting the post-boost voltage and the boost region includes a region in which the loss produced when boosting the post-boost voltage becomes smaller than the loss produced when not boosting the post-boost voltage.
