Abstract
A control apparatus for a vehicle including a three-phase AC motor and a power converter, the control apparatus includes an ECU. The ECU is configured to determine whether a rotation speed of the three-phase AC motor is equal to or less than a predetermined threshold and whether a stopping operation of the vehicle is performed, to determine that the vehicle stops when the rotation speed is equal to or less than the predetermined threshold and the stopping operation is performed, to determine whether the vehicle skids, and to switch a state of the power converter to a state where all on one side of the first and second switching elements are turned off and at least one on the other side of the first and second switching elements is turned on when the ECU determines that the vehicle stops and that the vehicle does not skid.
