    Abstract: A control device (30) calculates an upper limit value of a duty ratio (DR_Ulim) according to a voltage (Vm) from a voltage sensor (13) and a threshold voltage (OVb) when an overvoltage is determined to have been applied to a battery (B), and determines a duty ratio (DR) for providing switching control to NPN transistors (Q1, Q2) in a range lower than the calculated upper limit value of the duty ratio (DR_Ulim). The control device (30) uses the determined duty ratio (DR) to provide switching control to the NPN transistors (Q1, Q2). Then, an up-converter (12) converts a direct current voltage (Vb) from the battery (B) into the output voltage (Vm) such that an overvoltage is not applied to the battery (B).

    Abstract: A vehicle control apparatus (100) is provided with an upper controlling device (17b) and a lower controlling device (17a). The upper controlling deice has: a first determining device (172) configured to determine whether or not the number of revolutions of a three-phase AC motor (MG2) is less than or equal to a predetermined threshold value and whether or not a stop operation which can stop the vehicle is performed; a second determining device (172) configured to determine that the vehicle is stopped if it is determined that the number of revolutions of the three-phase AC motor is less than or equal to the predetermined threshold value and that the stop operation is performed; and a commanding device (172) configured to output a particular control command for setting the state of a power converter (13) to a particular state if it is determined that the vehicle is stopped. The lower controlling device controls the power converter to be in the particular state after a lapse of a predetermined period from the reception of the particular control command.

    Abstract: A control device for a vehicle is equipped with second determination means for determining that the vehicle is stopped when first determination means determines that a rotational speed of a three-phase alternating-current electric motor is equal to or lower than a predetermined threshold and that a stop operation is performed, control means for controlling an electric power converter such that a state of the electric power converter becomes a specific state where i) all the first switching are off and at least one of the second switching elements is on or ii) all the second switching elements are off and at least one of the first elements is on, and threshold setting means for setting the predetermined threshold based on a temperature of a magnet of the three-phase alternating-current electric motor.
