  • Patent number: 9601282
    Abstract: The power shut-off unit is equipped with two relays (2) connected to an external circuit, and a tabular baseplate (6). Multiple auxiliary electronic components (7) are mounted on the baseplate (6). The relays (2) are held so as to float over a mounting surface (13) via a pair of retaining members (8). A distance (d) equal to or greater than the thickness of the baseplate (6) is maintained between the relays (2) and the mounting surface (13). The baseplate (6) is not directly fixed to the mounting surface (13) and is connected to the relays (2) via multiple latching members (9). Because no load is acted upon the baseplate (6) by the relays (2), the baseplate (6) can be made thin.

  • Patent number: 9599054
    Abstract: When an accelerator pedal is released while a vehicle is running, a lockup clutch is unlocked. Simultaneously, ignition timing is retarded and a fuel-cut operation to stop fuel supply to an internal combustion engine is performed. However, when it is predicted that a fuel recovery is to be performed after unlocking the lockup clutch, execution of the fuel-cut operation is prohibited. A shock due to the fuel recovery after the fuel-cut operation performed when the accelerator pedal is released is thereby prevented.

  • Patent number: 9580068
    Abstract: A hybrid vehicle drive control system is configured to start an engine irrespective of a motor rotational speed or a driving scene. In the hybrid vehicle drive control system, upon receiving an engine startup request, the engine is started by engaging a first clutch provided between the engine and a motor using the torque of the motor. A second clutch is provided between the motor and the drive wheel. The second clutch is disengaged by a second clutch control operation to reduce the motor rotation speed as a result of the motor rotational speed control by a motor rotation speed-controlling operation. The control system may thus increase the maximum motor output enable torque to ensure the start of the engine by the surplus torque irrespective of a motor rotational speed or driving scene.

  • Publication number: 20170051826
    Abstract: A method controls a shift actuator with a sliding gear for a gearbox. The gearbox includes a control element for controlling a shift fork responsible for disengaging and engaging pinions on a shaft of the gearbox that receives torque from a traction machine powered by the on-board electrical system of the vehicle. The control element is positioned upstream of a mechanical spring-assist system and regulated in position by a DC actuating motor. The method includes temporarily raising a supply voltage applied to the actuating motor above a base voltage of an on-board electrical system during the disengaging and engaging the pinions.

  • Patent number: 9573584
    Abstract: A hybrid vehicle control device includes an engine start control unit which, at engine start, starts slipping a second clutch, sets a first clutch to a slip-engaged state, and sets the second clutch transmission torque capacity to less than or equal to a set torque limit value during cranking, maintains the slip state and cranks the engine, and when the engine is put in a drive state, controls the first clutch and the second clutch towards a fully engaged state. The engine start control unit is provided with a second clutch torque increase gradient control unit which, when performing cranking processing, performs first increasing processing for increasing the second clutch transmission torque capacity command value at a first increase gradient, and second increasing processing for increasing said value at a second increase gradient more gradual that the first increase gradient.

  • Patent number: 9577484
    Abstract: A rotary electric machine includes a stator and a rotor. The rotor has at least one permanent magnet arranged in a d-axis magnetic path. The rotor includes a magnetic gap part located between the permanent magnet arranged in the d-axis magnetic path of one pole and an adjacent magnet with a different polarity, such that a d-axis magnetic flux forms a d-axis bypass passing through an area other than the permanent magnet. The d-axis bypass provides a magnetic resistance in a d-axis direction that is set below a magnetic resistance in a q-axis direction that is orthogonal to the d-axis resistance.

  • Patent number: 9573586
    Abstract: A hybrid vehicle control device is provided with an engine, a motor, a mode switching mechanism and an engine start control unit. The motor is disposed in a drive system between the engine and a driving wheel for starting the engine and driving the driving wheel. The mode switching mechanism is operatively coupled to a connecting portion of the engine and the motor. The motor starts the engine upon an engine start request being outputted while traveling with only the motor as a drive source. The engine start control unit makes starting the engine more difficult, upon determining vehicle speed is increasing while a depression operation of an accelerator is occurring, until the rotational speed of the motor decreases, by performing an upshift operation that reduces a gear ratio by making a starting condition of the engine stricter as compared to a gear ratio prior to the upshift operation.
