Patents by Inventor Karl M. Jungbluth

Karl M. Jungbluth has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Vehicle and method to control rolling engagements
    Patent number: 9631723
    Abstract: When a vehicle driver selects reverse while a vehicle is moving forward, a transmission controller applies friction shift elements within the transmission to create a partial tie-up condition to decelerate the vehicle. Once the vehicle slows below a threshold speed, the controller engages a selectable one way brake and releases some of the friction shift elements to engage a reverse gear ratio.
    Type: Grant
    Filed: January 26, 2015
    Date of Patent: April 25, 2017
    Assignee: Ford Global Technologies, LLC
    Inventors: Karl M. Jungbluth, Christopher Marcus Williams, Kurt Howard Nickerson

  • Adapting stroke pressure of a transmission control element
    Patent number: 8180538
    Abstract: A method for controlling a transmission includes applying a reference stroke pressure to an oncoming control element while executing a downshift to a target gear, determining a stroke pressure adjustment in response to a turbine speed flare during the downshift, and re-executing the downshift while applying to the oncoming element an adapted stroke pressure that is a sum of the stroke pressure adjustment and the reference stroke pressure.
