Abstract: First and second motors have structures different from each other. A control device estimates a first magnet temperature of the first motor and a second magnet temperature of the second motor and controls a drive unit based on the first and second magnet temperatures. The control device estimates the first magnet temperature using a first parameter (the temperature of cooling oil of the first and second motors) and estimates the second magnet temperature using the temperature of the stator of the second motor. Since an appropriate parameter is selected from among a plurality of parameters concerning the state of the first and second motors, the first and second magnet temperatures can be estimated more accurately.

Abstract: 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.

Abstract: A maximum value selection unit (50) receives battery voltage values (Vb1, Vb2) and outputs the maximum value thereof to a lower limit value limiting unit (54). A maximum value selection unit (52) receives required voltage values (Vm1*, Vm2*) and outputs the maximum value thereof to the lower limit value limiting unit (54). The lower limit value limiting unit (54) outputs a voltage reference value (Vh*) by limiting the value so as not to fall below an output value of the maximum value selection unit (50). Switching commands (PWC1, PWC2) are generated based on a control computation using a combination of a voltage feedback control element and a voltage feedforward element, and a control computation using a combination of a current feedback control element and a voltage feedforward element, respectively.

Abstract: An ECU estimates an output allowable power of a power storage device based on the temperature and SOC of the power storage device. The ECU also calculates a threshold power based on the power required to start an engine. When the ECU determines that the output allowable power is lower than the threshold power, the up-converter is controlled such that the boosting rate of the up-converter is restricted to be below a prescribed value.
