  • Patent number: 7775338
    Abstract: A vehicle control device includes an actual drag torque calculating unit, which calculates the drag torque of a power transfer mechanism. A lubricating oil flow rate calculating unit determines the flow rate of lubricating oil according to the actual torque, and a reference drag torque calculating unit calculates a reference drag torque. In addition, a reference lubricating oil flow rate calculating unit calculates a reference lubricating oil flow rate according to the reference drag torque. A correction rate calculating unit then calculates a correction value corresponding to the rate of correction of the lubricating oil flow rate according to the lubricating oil flow rate and reference lubricating oil flow rate. A flow rate correction unit outputs a drive signal to an actuator which controls a lubrication oil flow rate according to the correction rate.

  • Patent number: 7678020
    Abstract: A vehicle clutch has a pushing member that is energized against a friction plane and transfers power from a driving power source when it touches the friction plane. The location of the pushing member can be retained even when power is shut off. After a signal from the key switch ends, the control apparatus stops the driving power source and the vehicle, engages the friction transfer mechanism, and then stops the system.

  • Patent number: 7507182
    Abstract: A controller, control method, and control system for a motor vehicle gear-type transmission enable a friction transmission unit to be controlled to an optimum position according to a particular motor vehicle state or the like. A transmission control unit changes, via at least one parameter that indicates a state of the gear-type transmission or of the vehicle, a position or pressure load at which the pressure member is caused to stand by while the driving shaft of the vehicle is in a stopped state or during changeover of the mesh unit that connects to one of the gear pairs.

  • Patent number: 7503233
    Abstract: In a torque assisted automated MT, an assist clutch is controlled to ensure that the transmission torque increase rate is reduced when disengaging a dog clutch while engaging the assist clutch. In a twin clutch type automated MT, in stepped speed change, one of the two clutches as the twin clutch is controlled in such a way that the transmission torque increase rate resulting from engagement is reduced with the passage of time, when disengaging the dog clutch prior to speed change while engaging the clutch corresponding to the input shaft in charge of offsetting the torque interruption.

  • Publication number: 20070202991
    Abstract: A vehicle equipped with a motor-operated mechanism that contains a clutch. The pushing member of the clutch is energized against a friction plane by an energizing mechanism and transfers power from a driving power source when it touches the friction plane. The location of the pushing member can be retained even when power is shut off. This structure prevents promotion of deterioration of a diaphragm spring in a state in which the clutch remains disengaged when the key switch is turned off. After a signal from the key switch stops, the control apparatus stops the driving power source and the vehicle, engages the friction transfer mechanism, and then stops the system.

  • Patent number: 7252622
    Abstract: When torque transmission through the transmitting torque variable mechanism (e.g., an assist clutch) is changed to torque transmission through a meshing gearing after the gearshift, a controlled variable per unit time when the transmitting torque variable mechanism is released is determined or varied according to the vehicle operating condition after a gearshift has been completed. A degraded gearshift feel as a result of axle vibration at the end of the gearshift can thereby be suppressed.

  • Publication number: 20070144861
    Abstract: A clutch mechanism includes: an input rotary member for receiving an input torque; a hub for receiving the torque from the input rotary member; first friction discs held by the hub; second friction discs arranged to be pressed against the first friction discs to achieve a torque-transmitting engagement therebetween; a drum supporting the second friction discs and stopped by the drum support bearing against movement in one axial direction; and an output rotary member for receiving the torque from the drum. Transmission of the torque from the drum to the output rotary member is achieved by a spline coupling therebetween. Axial movement of the drum in one direction is stopped by an end surface of a drum support bearing mounted in a housing. The hub is splined to the input rotary member for axial movement relative to the rotary input member.
