Abstract: On a vehicle, a converter converting and outputting a voltage, an inverter converting DC power output from the converter to AC power, and a motor driven by AC power supplied from the inverter are mounted. A control device calculates a requested voltage VHreq as an output voltage from a converter for bringing a degree of modulation Kmd of the inverter closer to a prescribed target degree of modulation Kmd#, calculates from target torque of the motor, a minimum voltage VHmin as a minimum value for an output voltage from the converter which can realize target torque of the motor, and controls the converter such that the output voltage VH from the converter is closer to a value which is greater one of the requested voltage VHreq and the minimum voltage VHmin.

Abstract: An inverter performs bidirectional DC/AC power conversion between a power line and a second MG so as to control an output torque of the second MG for generating vehicle driving force. A PM-ECU sets a torque command value of the second MG such that requested driving force for an entire vehicle is exerted on a drive shaft. An MG-ECU estimates, based on a rotation speed of the second MG, a magnitude of a drag torque acting as rotational resistance when the second MG rotates at zero torque, and stops the inverter in accordance with a difference between the estimated drag torque and the torque command value.

Abstract: A converter controls a system voltage, which is a DC link voltage of an inverter, in accordance with a voltage command value. The inverter outputs a rectangular wave voltage having the system voltage as amplitude to an AC motor during application of rectangular wave voltage control. During application of rectangular wave voltage control, a voltage command value for the system voltage is modified such that a current phase on a d-q plane of the AC motor is brought closer to a target current phase line. The target current phase line is set on an advance side relative to an optimal current phase line which is a set of current phases at which output torque is maximized for the same amplitude of a motor current in the AC motor.

Abstract: Fluctuations in output of an AC electric motor are restrained without increasing electromagnetic noise of a boost converter. When subjecting the AC electric motor to rectangular wave voltage control, output torque T is controlled by varying a voltage phase ?v. In a region where a voltage phase is large (?v=?2), fluctuations in torque T relative to changes in a DC voltage VH corresponding to the amplitude of a rectangular wave voltage are larger than in a region where the voltage phase is small (?v=?1). The AC electric motor is controlled such that the rectangular wave voltage control in a region where voltage phase ?v is larger than a limit-phase line PLN indicated by a set of limit phases set for each DC voltage VH is avoided.

Abstract: A hybrid vehicle generates vehicle driving force by the sum of a direct torque mechanically transmitted directly from an engine to a drive shaft through a power split device and an output torque of an MG. A PM-ECU selectively applies a running mode in which outputs of the engine and the MG are controlled such that the requested driving force for the entire vehicle is exerted on the drive shaft; and an S/D mode in which the requested driving force is exerted on the drive shaft by the direct torque in the state where the output torque of the MG is set at zero. An MG-ECU stops the operation of a power converter for controlling the output of the MG when the S/D mode is applied.
