If a running range is selected, a current conduction mode of a motor is set to a low speed mode in which a current is conducted through a first and second windings, when a rotation speed of the motor is less than a threshold value, and is set to a high speed mode in which a current is conducted through only the first winding, when the rotation speed is equal to or greater than the threshold value. If a neutral range is selected, control of the inverter is stopped, and, a regeneration suppression control is executed to switch the current conduction mode to the high speed mode, not only in a higher-side speed range where the rotation speed is equal to or greater than the threshold value, but also in at least a part of a lower-side speed range where the rotation speed is less than the threshold value.
