Abstract: There is provided a control apparatus for an automatic transmission AT into which driving forces from driving sources including an engine Eng and a motor/generator MG are inputted. The control apparatus includes: a second brake B2 engaged in a D range; an engagement start determining section (steps S2?S3?S4); and a determination inhibit section (steps S2?S5?S6). The engagement start determining section determines that second brake B2 has started the engagement in a case where a load of the motor/generator MG is increased by a predetermined quantity during the revolution number control and when the D range is selected and second brake B2 in the release state is engaged. The determination inhibit section inhibits the engagement start determination in a case where a switching from an HEV mode to an EV mode occurs.

Abstract: An information processing system includes an information bearing medium and an information reading unit. The information bearing medium has a two-dimensional array of unit data zones. Marks are provided on some of the unit data zones so as to form a digital code. Mark patterns of any two Y-directional adjacent unit data zone strings based on the arrangement of marks in an X-direction differ from each other.

Abstract: The purpose of the present invention is to provide a sealing device which has forward and reverse screw threads exhibiting a fluid-pumping action provided on a sliding portion of a seal lip, such that the pumping action is less susceptible to deterioration even with increasing wear on the screw threads and such that leakage of droplets from the screw threads is minimized. To achieve this, the forward and reverse screw threads which exhibit a pumping action on sealing fluid are arranged in a circle on the air-side lateral surface of the sliding portion of the seal lip. The forward and reverse screw threads each have a shape gradually increasing in thread height from the leading end of the lip to the air side. The forward screw threads and/or reverse screw threads are provided with seal protrusions for preventing leakage of droplets.

Abstract: A neutral determination device is provided with an inhibitor switch and a controller. The inhibitor switch outputs an inhibitor switch signal that indicates a vehicle running range of a vehicle. The controller is programmed to execute a neutral determination process upon determining the vehicle running range exists based on the inhibitor switch signal and a rotational speed control is being performed on a motor that is configured to output a force that drives the vehicle. The controller is programmed to determine existence of a neutral state of a control valve that is configured to selectively supply a control hydraulic pressure to a hydraulic pressure chamber of the clutch upon determining that a motor torque during the rotational speed control is smaller than an estimated motor torque based on a target transmission torque capacity of a clutch that selectively connects and disconnects the motor to and from a drive wheel.

Abstract: A hybrid vehicle control apparatus includes a first clutch disposed between an engine and a motor, and a second clutch disposed between the motor and a driving wheel. A lockup controller performs a lockup operation to shift the second clutch from slip state into completely engaged state when a predetermined lockup condition is satisfied under a condition that the second clutch is in the slip state. A second clutch transmitted torque capacity controller performs a lockup-condition second clutch control to control transmitted torque capacity of the second clutch to a value higher by a set quantity than an input torque to the second clutch while the lockup operation is being performed. The input torque corresponds to a state of depression of an accelerator pedal during the shifting of the second clutch from the slip state into the completely engaged state.

Abstract: 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. The three-dimensional shape is constructed by a projection or a groove extending in a parallel direction to the lip end. The projection or the groove is connected to the screws longitudinally in both end portions.

Abstract: Provided is a hybrid vehicle in which a motor/generator 5 is positioned between an engine 1 and an automatic transmission 3, the engine 1 and the motor/generator 5 are connected through a first clutch 6 and a second clutch 7 is provided between the motor/generator 5 and a drive road wheel 2. In an HEV mode in which the first clutch 6 is engaged, when deceleration of a vehicle is determined to be rapid deceleration of a threshold value or greater, the first clutch 6 is released and at the same time fuel supply to the engine 1 is stopped through an engine controller 21. Even when, due to rapid decelerating, the engine speed Ne drops to an idling speed or lower due to delay in the release of the first clutch 6, there is no combustion or explosion and thus floor vibration does not occur.

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.

Abstract: An engine start using an electric motor during a vehicle travel is performed by increasing an output torque of the electric motor in a slip state where a second frictional engagement element 3 connecting the electric motor 1 and a driving wheel slips. A controller determines a requested acceleration amount from a depression amount of an accelerator pedal. When the requested acceleration amount is significant, a different torque increment characteristic is applied, compared to a case where the requested acceleration amount is not significant. Thus, the internal combustion engine starts in a high response depending on the requested acceleration amount input by the driver, thereby improving a vehicle acceleration response.

Abstract: A hybrid vehicle control apparatus includes a first clutch disposed between an engine and a motor, and a second clutch disposed between the motor and a driving wheel. A lockup controller performs a lockup operation to shift the second clutch from slip state into completely engaged state when a predetermined lockup condition is satisfied under a condition that the second clutch is in the slip state. A second clutch transmitted torque capacity controller performs a lockup-condition second clutch control to control transmitted torque capacity of the second clutch to a value higher by a set quantity than an input torque to the second clutch while the lockup operation is being performed. The input torque corresponds to a state of depression of an accelerator pedal during the shifting of the second clutch from the slip state into the completely engaged state.
