  • Patent number: 10851843
    Abstract: A vehicle including a coupling device that includes (a) an engagement clutch mechanism for coupling an input side engagement member that is coupled to a drive power source of the vehicle and an output side engagement member that is coupled to a drive wheel of the vehicle; and (b) a cam mechanism for assisting engagement of the input and output side engagement members depending on a differential torque by which the input and output side engagement members are rotated differentially. The vehicle includes a control device configured, when the engagement of the input and output side engagement members is to be released, to cause a braking force to be applied to one of the input and output side engagement members such that the differential torque is reduced.

  • Patent number: 10501066
    Abstract: A control device for a power transmission device including an automatic transmission and a sub transmission is provided. The control device includes an electronic control unit. The electronic control unit is configured to perform a rotation speed decrease control in which at least one frictional engagement device is controlled to be an engaged state or a semi-engaged state at a time when switching of gear stage of the sub transmission is started or a time when the switching is started. The electronic control unit is configured to end the rotation speed decrease control during switching of the gear stage. The electronic control unit is configured to switch the sub transmission from the power transmission cutoff state to a state in which one of the high-speed engagement element and the low-speed engagement element is engaged, during disengagement of the at least one frictional engagement device.

  • Patent number: 10458492
    Abstract: An electronic control unit executes gradual reduction control when a friction clutch is to be maintained in a fully engaged state such that an input rotary member and an output rotary member rotate integrally. As a result, a motor current supplied to a motor is adjusted to a lower current value. Thus, an average current value of the motor current supplied to the motor when the friction clutch is to be maintained in the fully engaged state is appropriately reduced.

  • Patent number: 10293688
    Abstract: An electronic control unit switches a driving mode to a high-gear two-wheel driving mode when a first condition and a second condition are satisfied at the time of driving in a high-gear four-wheel driving mode, and switches the driving mode from the high-gear two-wheel driving mode to the low-gear driving mode when a third condition is satisfied in a state in which the first and second conditions are satisfied. Accordingly, it is possible to shorten a time required for switching to the low-gear driving mode after all of the first to third conditions are satisfied.

  • Patent number: 10245950
    Abstract: When a vehicle is switched from a two-wheel-drive mode to a four-wheel-drive mode during turning, rotation of a Rr dog clutch is synchronized by a synchro mechanism. Rotation of a Fr dog clutch is synchronized, by controlling coupling torque of a control coupling that transmits power to a rear wheel that provides an outer wheel during turning. Thus, rotation of the Fr dog clutch is also synchronized, so that shock at the time of engagement of the Fr dog clutch can be suppressed.
