Abstract: An overall loss L during non-execution of intermittent boosting (in ordinary boosting) is calculated from losses L1 and L2 of motors and a loss LC of a boost converter during non-execution of intermittent boosting. The overall loss L during execution of intermittent boosting is calculated from the losses L1 and L2 of the motors and the loss LC of the boost converter during execution of intermittent boosting. A minimum loss-time boosting voltage Vtmp at which the overall loss L provides a minimum loss Ltmp is set to a target voltage VH*. The boost converter is then controlled in a control state corresponding to the minimum loss-time boosting voltage Vtmp. An overall loss L during non-execution of intermittent boosting (in ordinary boosting) is calculated from losses L1 and L2 of motors and a loss LC of a boost converter during non-execution of intermittent boosting.

Abstract: A controller of an electrically powered vehicle includes an electronic control unit. The electronic control unit performs a switching control by a square wave control in a first switching mode when a rotation speed of the motor is equal to or higher than a first predetermined rotation speed. The electronic control unit performs the switching control by the square wave control in a second switching mode when the rotation speed of the motor is lower than the first predetermined rotation speed. The first predetermined rotation speed is a rotation speed lower than a first resonance region. The first switching mode is a mode of a switching pattern that suppresses LC resonance in the first resonance region. The second switching mode is a mode of a switching pattern that suppresses LC resonance in a second resonance region lower than the first predetermined rotation speed. A controller of an electrically powered vehicle includes an electronic control unit.

The voltage application unit is configured to apply a d-axis voltage to an electric motor including a salient-pole rotor during a stop of the electric motor. The current detecting unit is configured to detect a q-axis current flowing through the electric motor at the time when the d-axis voltage is applied. The estimating unit is configured to estimate a rotor position during a stop of the electric motor on the basis of the q-axis current detected by the current detecting unit. The voltage application unit is configured to set a voltage application time in correspondence with peak timing at which the q-axis current reaches a peak in a transitional response characteristic of the q-axis current at the time when the d-axis voltage is applied.
