Abstract: In a first slip suppression control by a first slip suppression control unit when a vehicle stops on a slope, an electronic control unit controls an output torque of an electric motor so that a rotation speed of an input rotation member of a hydraulic power transmission reaches a predetermined target rotation speed during stopping of an engine. The electronic control unit starts the engine when the output torque of the electric motor is greater than a predetermined torque. Accordingly, when the output torque of the electric motor at a rotation speed under a slip suppression control is insufficient, the output torque of the engine can be used and thus a locked state of the electric motor is appropriately prevented.

Abstract: In response to the driver's brake OFF operation after a gearshift operation of a gearshift lever to a parking position, a motor MG2 is controlled to sequentially output a torque in a backward direction of a vehicle and a torque in a forward direction of the vehicle. Gears are accordingly engaged in a parking lock mechanism during rotation of a parking gear by an angle corresponding to half a tooth in the backward direction of the vehicle or during subsequent rotation of the parking gear by an angle corresponding to one tooth in the forward direction of the vehicle. This arrangement effectively ensures gear engagement in the parking lock mechanism, while desirably reducing a moving distance from a vehicle stop position before gear engagement in the parking lock mechanism.

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.
