  • Methods and system for stopping an engine of a hybrid vehicle
    Patent number: 11628818
    Abstract: A method and system for operating a vehicle that includes an automatic transmission with a torque converter clutch is described. In one example, the method includes predicting a time that the torque converter clutch will open so that stopping rotation of the engine may be requested before the torque converter clutch is opened. The stopping rotation of the engine is requested to conserve fuel.
    Type: Grant
    Filed: July 7, 2020
    Date of Patent: April 18, 2023
    Assignee: Ford Global Technologies, LLC
    Inventors: Yanan Zhao, Christopher John Teslak, Stuart N. Ford, Ralph Wayne Cunningham, Judhajit Roy, Chenliu Stephen Lu, Girish Gokul Chennupalli
  • Roadway vehicle speed planning
    Patent number: 11292465
    Abstract: A traffic controller includes a controller configured to reject a request and issue a speed requirement based on a priority to cause a speed of a one of a plurality of vehicles to be within a speed band before entering a road. The rejection is responsive to receiving the speed request from the one approaching the road having priority less than a predetermined threshold and outside of a speed band and a predetermined acceleration band of vehicles on the road.

  • Lateral motion control for cornering and regenerative braking energy capture
    Patent number: 10752288
    Abstract: A vehicle includes motors each configured to drive a front wheel of the vehicle, an electronic limited slip differential (eLSD) between rear wheels of the vehicle, and a controller to, responsive to vehicle turning and a power of each of the motors being less than a maximum value, alter operation of the motors to increase a difference between the powers. Otherwise, the controller operates the eLSD to bias torque toward one of the rear wheels.
