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.
