    摘要: The present invention provides a more efficient method for maintaining the hydraulic actuation of a selectively engageable torque transmitting device in a vehicle. The method includes generating a predetermined pressure level of a hydraulic fluid such as, for example, with a pump. The pressurized hydraulic fluid is transferred through an open valve and to a selectively engageable torque transmitting device such that the selectively engageable torque transmitting device is engaged. Thereafter, the valve is closed so that the predetermined pressure level of hydraulic fluid at the selectively engageable torque transmitting device remains relatively constant. Accordingly, the selectively engageable torque transmitting device remains engaged without continuously generating additional pressure such that the fuel economy of the vehicle is improved. A corresponding apparatus is also provided.

    摘要: The present invention relates to the use of a magnetic sensor to detect the speed of transmission clutch plates or clutch hub. A clutch fiber plate, which is mechanically linked to a buried (or inwardly nested) transmission component, is serrated to generate detectable pulsations or fluctuations in the magnetic intensity of the clutch fiber plate as it rotates. The speed of the buried transmission component is useful in controlling a second clutch arrangement to reduce engine torsional pulses by generating a predetermined amount of slip upon engagement. Moreover, the sensor is configurable to determine the acceleration of the clutch fiber plate to control engine acceleration during a vehicle launch. The sensor is mounted to the transmission housing radially superjacent the clutch fiber plate; therefore, the axial space claim for the transmission does need not increase to accommodate the sensor.

    摘要: Embodiments of the invention provide an image display mode for displays, such as a television, that do not use the entire display field for displaying an image. A user selectable modification of the image display is provided, where the image may be stepped a predefined column of pixels, or predefined row of pixels, depending on viewing format, at a time at a very slow rate. The image may be stepped a predefined column of pixels per predefined time period until it is entirely to one side of the display, at which point it may be slowly stepped back to the other side of the display.

    摘要: A torque-transmitting mechanism having a latching apparatus includes a frictional drive connection between two components of a transmission mechanism. The torque-transmitting mechanism is controlled in engagement and disengagement through an apply piston to which an apply component is presented. The latching mechanism will prevent disengagement of the torque-transmitting mechanism even when the apply force is disestablished. The latching mechanism is provided with a controlled release to permit the apply force to be reestablished and thereafter control disengagement of the torque-transmitting mechanism.

    摘要: A torque-transmitting mechanism has an electric motor apply apparatus. The electric motor is operable to control a drag torque on a rotatable plate for a torque-to-thrust apparatus. The control of the rotatable plate by the electric motor and drag torque results in a thrust force being applied to the torque-transmitting mechanism such that the torque-transmitting mechanism is conditioned to transmit torque between two members of a power transmission.
