  • Publication number: 20150065297
    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: When a P lock state is set on the basis of a predetermined request signal for setting the P lock state, a P position indicator lamp (62) is turned on or off on the basis of the status of power supplied to the vehicle (10). For example, when the P lock state is set, the P position indicator lamp (62) is turned off when the power status is an ALL-OFF status where a combination meter (56), or the like, is not turned on or is raised to an ACC-ON status; whereas, when the P lock state is set, the P position indicator lamp (62) is turned on when the power status is an IG-ON status, when the power status is changed from the IG-ON status during vehicle driving to the ACC-ON status, or within a predetermined period of time from when the power status is changed from the IG-ON status to the ALL-OFF status.

  • Patent number: 7698042
    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.

  • Patent number: 7617896
    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.
