Patent number: 9644743Abstract: The invention provides a sealing device which can inhibit an external dust in an atmospheric side from intruding into a lip end, thereby inhibiting a sealing fluid leakage by trapped dust. In a sealing device inhibiting leakage of a sealing fluid in an inboard side to an atmospheric side, coming into contact with a shaft by a seal lip end and circumferentially having in an atmospheric side inclined surface of the seal lip with a plurality of screws exerting a pumping action to the sealing fluid, a three-dimensional shape for preventing the dust intrusion is provided between the screws so as to inhibit the external dust intrusion in the atmospheric side toward the lip end.

Patent number: 9573584Abstract: 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.Type: GrantFiled: December 20, 2013Date of Patent: February 21, 2017Assignee: NISSAN MOTOR CO., LTD.Inventors: Hiroki Matsui, Hiroki Shimoyama

Patent number: 9573586Abstract: 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.Type: GrantFiled: March 13, 2014Date of Patent: February 21, 2017Assignee: Nissan Motor Co., Ltd.Inventors: Hiroki Matsui, Fumuhiro Yamanaka

Patent number: 9533680Abstract: Present invention provides a control device for hybrid vehicle which can ensure acceleration performance while suppressing second clutch engagement shock at engine start. The control device has second clutch (CL2) which is interposed between motor/generator (MG) and driving wheels (rear-left and right wheels RL, RR) and whose transmission torque capacity is variable, a second clutch slip amount controlling section (400b) performing full engagement operation that shifts second clutch (CL2) from slip state to full engagement state at a time when lock-up condition of the second clutch (CL2) is satisfied (S107) in the slip state of the second clutch (CL2). The second clutch slip amount controlling section (400b) first increases transmission torque capacity of second clutch (CL2) at first increase gradient (R1) (S109) and subsequently increases the transmission torque capacity of the second clutch (CL2) at second increase gradient (R2) that is gentler than the first increase gradient (R1) (S111).Type: GrantFiled: December 20, 2013Date of Patent: January 3, 2017Assignee: NISSAN MOTOR CO., LTD.Inventor: Hiroki Matsui
