  • Patent number: 10753472
    Abstract: A control device that includes an electronic control unit that is configured to perform neutral travel control that controls the transmission apparatus to enter a neutral state in which power is not transferred during rotation of the wheel, wherein the electronic control unit performs switching between an engaged neutral state in which a particular engagement device of the plurality of engagement devices is put in an engagement state and the transmission apparatus is put in a state in which power is not transferred and a released neutral state in which all of the plurality of engagement devices are put in a released state and the transmission apparatus is put in the state in which power is not transferred, based on at least a vehicle speed during the neutral travel control.
    Type: Grant
    Filed: February 19, 2015
    Date of Patent: August 25, 2020
    Assignee: AISIN AW CO., LTD.

  • Patent number: 9254839
    Abstract: A control device for a vehicle. While subject control is performed, a second engagement control unit controls the engagement pressure of the second engagement device to a mid-control set pressure that has been set to be equal to or more than a first engagement pressure and equal to or less than a second engagement pressure. The first engagement pressure is a lower limit engagement pressure capable of maintaining the second engagement device in the directly coupled engaged state, in a state in which requested torque that is torque required to be transmitted to the wheels is transmitted to the wheels. The second engagement pressure is a lower limit engagement pressure capable of maintaining the second engagement device in the directly coupled engaged state, in a state in which maximum output torque of the rotary electric machine is transmitted to the wheels.
