Abstract

An electric vehicle is provided with an electric motor and a transmission capable of being shifted by a shift mechanism from a neutral state to a start-up speed stage selected state in which a speed stage for start-up of the vehicle has been selected. On a request for a shift from the neutral state to the start-up speed stage selected state, an ECU performs the requested shift by controlling the shift mechanism. If the shift to the start-up speed stage selected state is not completed within a first specified time, the ECU performs a rotating position control in which the motor is controlled to produce a predetermined minute torque in forward and backward rotation directions of the motor, alternately, and a gear of the speed stage for start-up is caused to oscillate in a rotation direction by the minute torque being transmitted to an input shaft of the transmission.
