  • Patent number: 9945432
    Abstract: A drive power distribution device includes a hydraulic pressure sealing-type hydraulic pressure control device for making an operation noise of an on-off valve such as a solenoid valve less recognizable to occupants of a vehicle. By closing the on-off valve and driving the oil pump, a hydraulic pressure detected using a hydraulic pressure detection means reaches a target hydraulic pressure, and fastening power of a hydraulic clutch is maintained at an oil pressure of hydraulic fluid sealed in an oil passage until the on-off valve is opened. The drive power distribution device closes the solenoid valve when the hydraulic pressure is detected to be equal to or less than a predetermined threshold hydraulic pressure and equal to or less than a predetermined threshold vehicle speed. This can prevent synchronization between an accelerator operation by a driver and a closing operation of the solenoid valve.

  • Patent number: 9555795
    Abstract: A hybrid vehicle includes an engine coupled to a planetary gearset and an electric motor configured to provide motor torque directly to a torque transfer set. An overdrive clutch is configured to, when engaged, bypass at least a portion of engine torque to an overdrive shaft directly connected to the torque transfer set. This allows the engine to also provide torque directly to the torque transfer set along with the motor in an overdrive mode of operation. At least one controller is programmed to control the motor and/or the engine based on an estimated amount of torque transferred through the overdrive clutch.

  • Patent number: 9522679
    Abstract: A vehicle controller includes an hybrid vehicle (HV) ECU, a motor-generator (MG) ECU, a brake ECU, a first communication line that enables one-to-one connection between the HV ECU and the MG ECU, and a second communication line that enables connection among plural ECUs including the HV ECU and the brake ECU. The MG ECU calculates an operation torque of first and second MGs. The MG ECU is communicable with the brake ECU via the second communication line. In addition, the controller includes a microcomputer that serves as a travel state determiner for determining whether a travel state of a hybrid vehicle is a transition state in which a drive wheel alternatively slips and grips. Based on a determination result of the microcomputer, the controller switches to the first communication line in a normal state and to the second communication line in the transition state.

  • Patent number: 9428051
    Abstract: A disconnectable all-wheel drive vehicle driveline having a primary driveline, a power take-off unit (PTU), a secondary driveline, a hydraulic pump and a driveline actuator. The PTU has a PTU input member, which is driven by the primary driveline, a PTU output member and a first coupling that selectively couples the PTU input and output members. The secondary driveline includes a second coupling that selectively inhibits power transmission through the secondary driveline. The hydraulic pump is configured to operate the first coupling but is powered by a synchronization event in which the second coupling is engaged so as to back drive the PTU output member.

  • Patent number: 9387095
    Abstract: A prosthesis or an orthosis such as a hand prosthesis (10) comprises a moveable component (12). The moveable component (12) has a motor (14) operable to drive a worm gear (16). The hand prosthesis (10) also comprises a worm gear wheel 18 fixedly mounted on a support member (20). The moveable component (12) extends generally tangentially with respect to the worm gear wheel (18) and is mounted for rotation about the worm gear wheel (18). The worm gear (16) is in engagement with the worm gear wheel (18) such that, when the motor (14) is operated in use of the hand prosthesis (10), the moveable component (12) rotates about the worm gear wheel 18. The moveable component (12) includes two electrical contact members (50a) and (50b) and the worm gear wheel (18) includes two electrical contact surfaces (52a) and (52b).
