20120065023 | SYSTEM AND METHOD FOR CONTROLLING AMOUNT OF TIME NEEDED TO COMMENCE TRANSMITTING ENGINE TORQUE IN A VEHICLE - A method controls an amount of time required to commence transmitting torque of an internal combustion engine equipped with a stop/start feature to a transmission configured to transmit the torque of the engine to drive-wheels in a vehicle. The method includes determining whether a start of the engine is likely. The method also includes pre-filling with fluid a hydraulically-actuated clutch that is configured to connect the engine to the transmission when the start of the engine is likely. Accordingly, the amount of time required to commence transmitting torque of the engine to the transmission is reduced. A system employs the method for controlling an amount of time required to commence transmitting torque of the engine. | 03-15-2012 |
20120065819 | METHOD OF CONTROLLING A HYBRID POWERTRAIN TO ENSURE BATTERY POWER AND TORQUE RESERVE FOR AN ENGINE START AND HYBRID POWERTRAIN WITH CONTROL SYSTEM - A method includes determining an amount of power currently available from a battery for tractive torque as an amount of power stored in the battery less an amount of power required to power other vehicle components, and less an amount of power required to start the engine. An output torque limit when torque is provided only by the motor and power required to provide the output torque limit are determined based on test data. A maximum output torque is calculated by multiplying the amount of power determined to be currently available for tractive torque by a ratio of the output torque limit to the amount of power required to provide the output torque limit. The current output torque may be reduced at a predetermined rate until within a predetermined range of the lesser of the maximum output torque and the output torque limit if an engine start is requested. | 03-15-2012 |
20120283900 | ACTUATOR TORQUE PRODUCTION DIAGNOSTIC - An example hybrid vehicle includes a control unit that generates a control signal representing an expected torque, a first actuator that generates a first torque, a second actuator that generates a second torque associated with operating characteristics of the second actuator, and a gearbox that can receive the torque generated by the first and second actuators. A controller can determine whether the first torque produced by the first actuator is substantially the same as the expected torque based on one or more operating characteristics of the second actuator. An example method includes deriving an actual torque of the first actuator based on the operating characteristics of the second actuator, defining a torque deviation from the actuator torque and the expected torque, comparing the torque deviation to a calibration threshold, and diagnosing that the first actuator has failed if the torque deviation exceeds the calibration threshold. | 11-08-2012 |
20150217761 | ENGINE AUTOSTART SOURCE SELECTION - A vehicle includes an engine, a transmission, and an electrical system. The electrical system has an auxiliary starter motor connected to a crankshaft of the engine, a high-voltage motor generator unit (MGU) connected to the crankshaft, and a controller. Execution of instructions by a processor causes the controller to determine a set of powertrain conditions in response to a requested autostart of the engine, e.g., state of charge and/or power limits of a high-voltage energy storage system (HV-ESS), torque limits of the MGU, and/or a crank angle of the engine. The controller determines whether the requested autostart may not succeed relative to a time or noise standard using the set of powertrain conditions, and transmits an autostart command to the MGU when the requested autostart may succeed. The controller transmits the autostart command to the auxiliary starter motor when the requested autostart will not succeed. | 08-06-2015 |

20090060152 | System and Method for Controlling a Digital Video Recorder on a Cable Network - A system and method for controlling a digital video recorder on a cable network. Signaling associated with the answering or initiation of a digital telephone call by a digital telephone subscriber is used to issue commands to a digital video recorder (DVR). A signal is generated by an MTA when the telephone is enters an “off-hook” state and sent to the DVR to initiate recording of a program being viewed by the called party. When the phone goes “on-hook”, the called party resumes watching the program from exactly where it was interrupted. The MTA may be connected directly to the VTD/DVR and the telephone state is determined by the DVR from information provided by the MTA. Alternatively, a soft switch monitors signaling from the MTA indicative of the state of the called telephone. A telephone state message comprising the telephone state information is then sent over an out-of-band channel/path to a DVR client within the VTD. The DVR client uses the telephone state information to control a DVR. | 03-05-2009 |

20100320302 | In-Line Formed Core Supporting a Wound Web - A web is wound onto an in-line core instead of a separate core. At the start of the winding process, a core-forming substrate attached to the leading edge of the web is wound into an in-line core. The web is wound around the in-line core. For streaming operation, a composite substrate-web stream comprising an alternating sequence of attached core-forming substrate segments and web segments is produced. The first core-forming substrate segment is wound into a first in-line core, and the first web segment is wound around the first in-line core. The composite substrate-web stream is cut. The second core-forming substrate segment is wound into a second in-line core, and the second web segment is wound around the second in-line core. The composite substrate-web stream can be slit longitudinally to produce multiple composite substrate-web stream strips. Multiple composite substrate-web stream strips can be wound in parallel on a single mandrel. | 12-23-2010 |
