  • Publication number: 20230364979
    Abstract: A transmission mechanism transmits rotation transmitted from a distribution differential gear mechanism to an output member. The distribution differential gear mechanism, a first distribution output gear, and a first engagement device are disposed on a first axis. A first rotary electric machine and a first rotary electric machine drive gear are disposed on a second axis. A transmission engagement device of the transmission mechanism is disposed on a third axis. An axial direction of the first rotary electric machine includes a first axial side where the first rotary electric machine is disposed with respect to the first rotary electric machine drive gear, and a second axial side opposite to the first axial side. The distribution differential gear mechanism is disposed on the second axial side of the first distribution output gear and the first engagement device.

  • Patent number: 8914174
    Abstract: A control device for controlling a vehicle drive unit including an input member drivingly connected to an engine; an output member drivingly connected to a wheel; and a transmission device that includes engagement elements, that switches between shift speeds by control of engagement and disengagement of engagement elements, and that transmits a rotational driving force of the input member to the output member at a speed changed at a speed ratio of each of the shift speeds. The control device includes a control unit that controls the transmission device to achieve a one-way transmission speed in a running idle state in which a vehicle is running while the rotational driving force of the input member is not transmitted to the output member and a rotational speed of the engine is controlled to a predetermined idle speed.

  • Patent number: 8280599
    Abstract: A vehicle control device where, the transmission apparatus is provided with a state in which the rotational driving force is not transmitted from the output member to the input member when a first engaging element is engaged; the vehicle control device is provided with a control unit that controls the transmission apparatus to engage the first engaging element by a hydraulic pressure from the electric pump for implementing the state in an idle stop state in which the vehicle is in a moving state and the engine is stopped; in a case where a travel speed of the vehicle is not greater than a predetermined release threshold value, the first engaging element is engaged by the hydraulic pressure from the electric pump; and in a case where the travel speed of the vehicle is greater than the predetermined release threshold value, all of the engaging elements are released.
