Abstract: PROBLEM TO BE SOLVED: To avoid unexpected regenerative breaking of an electric motor and surely suppress the overcharging of a secondary battery, even if angle shift occurs in a sensor for detecting the rotation angle of the rotary shaft of the electric motor.SOLUTION: When controlling the motor by setting current instructions Id*, Iq* so that a current Id in the minus direction is flown in a d-axis and the current is not flown in a q-axis, the rotation angle θ is corrected in a direction from regeneration to powering by correcting the rotation angle θ from a rotation angle sensor used for controlling to a reverse rotation direction during the normal rotation of the motor and correcting it to a normal rotation direction during the reverse rotation of the motor. As a result, even if offset error is included in the rotation angle sensor, a current in the reverse direction of the rotation direction of the motor MG2 is not flown in q-axis, namely a regenerative torque can be made not to be output by controlling the motor MG2 based on the corrected rotation angle θ. As a result, unexpected regeneration of the motor can be prevented and the overcharging of the secondary battery can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To appropriately detect abnormality in shut-down operation of a switching element, in a boost-less power unit.SOLUTION: During a regenerating operation of a rotating machine M, a power supply line LINE is temporarily brought into a cut-off state by a shut-down operation of a switching element Q. On the basis of whether or not a voltage VH at a side of an inverter 14 is increased to a voltage VB of an accumulation device 12 or higher while the power supply line LINE is brought into the cut-off state, it is determined whether a connecting/disconnecting operation of the power supply line LINE by the switching element Q is normal or abnormal. Therefore, although abnormality in shut-down operation of the switching element Q during normal operation can not be detected in a power unit 10, an abnormal state which may disable the shut-down operation such as a circuit failure of a driver circuit 16 or an ON failure of the switching element Q can be detected.

Abstract: PROBLEM TO BE SOLVED: To assure output torque controllability at switching of a control system of a motor drive system having such control structure that the system switches between a pulse width modulation (PWM) control method and square wave voltage control method.
SOLUTION: At square wave voltage control, a torque feedback is performed for adjusting voltage phase ϕv of a square wave voltage according to a deviation from a torque command value Trqcom of a torque estimation value Trq. A torque estimating part 420 calculates the torque estimation value Trq using motor currents Id and Iq acquired from detection values of a current sensor 24 and a rotational angle sensor 25, like a PWM control method. In short, a status value (sensor detection value) of an AC motor M1 used for motor control is identical for both the square wave voltage control method and PWM control method.
