  • US Patent:
    8406974, Mar 26, 2013
  • Filed:
    Mar 29, 2010
  • Appl. No.:
    12/748516
  • Inventors:
    Shawn Adam Holland - Westland MI, US
    Jeffrey James Tumavitch - Livonia MI, US
    Steve Craig Meisner - Dexter MI, US

  • Assignee:
    Ford Global Technologies, LLC - Dearborn MI
  • International Classification:
    G06F 19/00
  • US Classification:
    701 58, 701 60, 701 68
  • Abstract:
    The present disclosure relates to methods of detecting misalignment in a transmission synchronizer and methods of alignment. Detection of misalignment is accomplished via monitoring a performance characteristic of a power source configured to provide an engagement force to the synchronizer. Where misalignment is detected a predetermined torque is applied to the input or output side of the synchronizer to rotationally align synchronizer components.
  • Method And System For Providing A Voting Strategy For Determining A Mode State In A Shift-By-Wire Transmission

  • US Patent:
    8634995, Jan 21, 2014
  • Filed:
    Dec 9, 2011
  • Appl. No.:
    13/316117
  • Inventors:
    Brian J Deurloo - Howell MI, US
    Mark Edward Zyskowski - Dearborn MI, US
    Christopher Lee Danks - Northville MI, US
    Richard Reynolds Hathaway - Livonia MI, US
    Jeffrey James Tumavitch - Livonia MI, US
  • Assignee:
    Ford Global Technologies, LLC - Dearborn MI
  • International Classification:
    G06F 7/00
  • US Classification:
    701 51, 701 291, 701 36, 701 62, 701 64, 477 34, 477 97, 1922194, 1922201, 1922202
  • Abstract:
    A voting strategy is used to determine the mode state of a transmission when a vehicle is restarted. A Powertrain Control Module, a Transmission Range Control Module, and a Gear Shift Module communicate through a communication network during execution of the voting strategy. Each module stores a remembered mode state (Normal, Neutral Hold, Neutral Tow, etc. ) of the transmission in non-volatile memory. Upon module initialization, the Powertrain Control Module will compare its own remembered mode state of the transmission with the remembered mode state reported by the other two modules. A basic voting strategy is that if two of the three modules report the same remembered mode state then the Powertrain Control Module changes the transmission to that same mode state.

    13/772328
  • Inventors:
    Jeffrey James Tumavitch - Livonia MI, US

  • US Patent:
    8648689, Feb 11, 2014
  • Filed:
    Feb 14, 2012
  • Appl. No.:
    13/396179

  • Assignee:
    Ford Global Technologies, LLC - Dearborn MI
  • International Classification:
    G05B 23/02
  • US Classification:
    340 343, 340 105, 340438, 292216, 70237
  • Abstract:
    A system includes a controller that executes a method for determining failure of the door latch sensor using both the door latch sensor and a door lock sensor. If the door latch sensor is faulty, the controller adjusts an automatic feature of the vehicle based on a door lock signal instead of a door state signal. The controller is also configured to mark the door latch signal as faulty if the door latch system is not functioning properly by using a fault counter that tracks the door lock sensor.
  • Method And System For Providing A Brake Transmission Shift Interlock Override Mode In A Shift-By-Wire Transmission

  • Assignee:
    FORD GLOBAL TECHNOLOGIES, LLC - Dearborn MI
  • International Classification:
    B60W 10/10
  • US Classification:
    701 55
  • Abstract:
    A method and system provides a Brake Transmission Shift Interlock Override mode in a vehicle including a shift-by-wire transmission. With power applied and ignition on, a driver will press and hold an override switch for a calibrated time. While the override switch is pressed, the driver presses a non-Park button for another calibrated time. The result will be that the vehicle is placed in the selected range wherein the transmission will not automatically shift to Park upon detecting a triggering event. The driver is able to shift the vehicle from Park, even if an electrical failure prevents the transmission from shifting out of Park. As such the vehicle can be driven until the failure is serviced.

  • Assignee:
    FORD GLOBAL TECHNOLOGIES, LLC - Dearborn MI
  • International Classification:
    F16H 61/18
  • US Classification:
    701 62
  • Abstract:
    A method and system provides a Neutral Hold mode in a vehicle having a shift-by-wire transmission with a return to park feature. The Neutral Hold mode is entered upon detecting when the transmission control mechanism has been used a first time to select Neutral when a driver's door is open or has been used a second time to select Neutral. When in Neutral Hold mode, the transmission will stay in Neutral and not shift to Park upon detecting that a driver has exited the vehicle.
  • Method And System For Providing A Neutral Tow Mode In A Shift-By-Wire Transmission

    20130151096, Jun 13, 2013
  • Filed:
    Dec 9, 2011

  • Assignee:
    FORD GLOBAL TECHNOLOGIES, LLC - Dearborn MI
  • International Classification:
    F16H 61/18
  • US Classification:
    701 62
  • Abstract:
    A method and system provides a Neutral Tow mode in a vehicle with a shift-by-wire transmission by displaying a Neutral Tow mode option when the transmission control mechanism has been used to select Park, an ignition switch is on, and an engine is off or an information button has been pushed and entering a Neutral Tow mode upon detecting a triggering event. The Neutral Tow mode is canceled upon detecting a certain sequence of events, such as turning on the ignition switch, depressing and holding a brake pedal, and selecting Park. When in Neutral Tow mode the transmission will stay in Neutral, without automatically shifting to Park or using battery power, thereby enabling the vehicle to be towed long distances without draining battery power.
