  • Patent number: 11084375
    Abstract: A drive force transmission apparatus is mountable on a four-wheel drive vehicle switchable between a four-wheel drive mode that transmits a drive force of an engine to front wheels and rear wheels, and a two-wheel drive mode that transmits the drive force to only the front wheels. The drive force transmission apparatus allows adjustment of the drive force to the rear wheels, and includes a multi-plate clutch, a piston for axially pressing the multi-plate clutch, an actuator for axially moving the piston, and a control unit for controlling the actuator. Upon satisfaction of a predetermined condition that indicates a high probability of the vehicle needing to be switched from the two-wheel drive mode to the four-wheel drive mode, the control unit causes the actuator to displace the piston by a predetermined amount with respect to an initial position of the piston toward the multi-plate clutch.

  • Patent number: 10507727
    Abstract: In a four-wheel-drive vehicle, a hydraulic unit has an electric motor, to which a motor current is supplied from a control device, and a pump that is actuated by rotation of a motor shaft, and a drive force transfer device has a piston that is moved by the pressure of working oil discharged from the pump, and a friction clutch that is switchable between a transfer state and a blocked state, in which transfer of a drive force to rear wheels is allowed and blocked, respectively, in accordance with movement of the piston. The control device detects the presence or absence of an abnormality of a flow passage forming member, which forms a flow passage for working oil, in accordance with at least any of a motor current and the number of revolutions of a motor shaft at the time when the motor shaft is rotated by applying a voltage to the electric motor.

  • Patent number: 10480597
    Abstract: A clutch apparatus includes a clutch hub, a clutch drum, a multi-plate clutch having inner clutch plates and outer clutch plates, a piston for pressing the multi-plate clutch, an electric motor, a moving mechanism for moving the piston in an axial direction in accordance with the amount of rotation of the electric motor, and a control unit for controlling the electric motor. When increasing a rotational force that is transmitted between the clutch hub and the clutch drum by increasing electric current that is supplied to the electric motor, the control unit moves the piston in the axial direction by temporarily supplying the electric motor with the electric current having a first current value that is greater than a second current value corresponding to a target rotational force that needs to be transmitted between the clutch hub and the clutch drum.

  • Patent number: 9331854
    Abstract: Each of ECUs counts the number of messages transmitted for each of CAN IDs. A transmission node that has transmitted a main message produces an MAC from a data field and the CAN ID in the main message and a counter value corresponding to the CAN ID, and transmits the MAC as an MAC message. A reception node that has received the main message produces an MAC from the data field and the CAN ID contained in the main message and the counter value corresponding to the CAN ID, and determines whether the MAC matches the MAC contained in the MAC message. By so doing, verification whether the main message is valid or not can be made. According to this configuration, message authentication by the MAC can be made without changing a CAN protocol.
