Patent number: 11167792Abstract: A guidance system identifies a path on a field and then calculates a position and heading of a trailer relative to the path. The guidance system steers a vehicle connected to the trailer based on the calculated trailer position and heading to minimize the trailer positional error and more quickly and accurately align the trailer with the path. The guidance system may align the trailer with the path while steering the vehicle in a reverse direction and may steer the vehicle based on a predicted trailer position and heading.Type: GrantFiled: February 15, 2019Date of Patent: November 9, 2021Assignee: AGJUNCTION LLCInventors: Eran D. B. Medagoda, Timothy J. Sullivan, Brendan M. Joiner, Andreas F. Ramm, Tri M. Dang

Patent number: 10890922Abstract: A navigation system aids a driver of a collection vehicle in keeping pace and distance with a lead harvester while collecting grain. The navigation system can be used for any leader-follower vehicle drive formation. A navigation system steers the head vehicle based on a continuously known position and attitude. Navigation data for the lead vehicle is broadcast to a following collection vehicle. A navigation system in the following vehicle processes the lead vehicle navigation data to determine a relative position and attitude. The navigation system in the following vehicle generates steering and speed commands based on the relative position and attitude to automatically drive to a designated target position alongside the lead vehicle. In one example, an artificial oscillation is induced into the target position to more evenly distribute material in the following vehicle.Type: GrantFiled: November 10, 2016Date of Patent: January 12, 2021Assignee: AGJUNCTION LLCInventors: Andreas F.

Patent number: 10416675Abstract: A line acquisition system generates a curvature profile based on initial vehicle states (starting position, heading, curvature and speed), vehicle steering capabilities (calibrated vehicle curvature and curvature rate limits), and initial vehicle position errors relative to the destination path. The curvature profile describes changes in vehicle curvature over a path distance from a current position to a destination path. The line acquisition system constructs an acquisition path from a combination of clothoid, circular arc, and straight lines corresponding with different segments of the curvature profile. The acquisition path can be displayed on a user interface allowing a vehicle operator to observe, prior to automatic steering engagement, the path the vehicle would take from a current state to the destination path.Type: GrantFiled: April 10, 2017Date of Patent: September 17, 2019Assignee: AGJUNCTION LLCInventors: Tri M.

Patent number: 10266201Abstract: A guidance system may derive a K-turn path when a vehicle reaches an end of a first way line in a field. The guidance system may send the K-turn path to a steering controller to turn the vehicle around in a headland area to the beginning of a second way-line in the field. A first segment of the K-turn path may turn the vehicle along a first path in a forward direction and a second segment of the K-turn path may turn the vehicle along a second path in a reverse direction. A third segment of the K-turn path may turn the vehicle along a third path in the forward direction to a starting location of the second way-line. The K-turn path uses less area than other types of turns reducing the amount of headland used for turning around the vehicle.Type: GrantFiled: November 10, 2016Date of Patent: April 23, 2019Assignee: AGJUNCTION LLCInventors: Tri M.

Patent number: 10209714Abstract: A line acquisition system predicts and displays an acquisition path to reduce the uncertainty surrounding the path taken by a vehicle when acquiring a destination path. The line acquisition system calculates the drivable acquisition path based on the current states of the vehicle, such as position, speed, heading, and curvature. The line acquisition system continually updates and displays the acquisition path as the vehicle is manually steered by the user. When the user engages a steering controller, the last calculated acquisition path is used to automatically steer the vehicle onto the destination path. Displaying the acquisition path allows the user to observe, prior to automatic steering engagement, the path the vehicle would take from its current state to the destination. The user can then decide whether the predicted acquisition path will interfere with terrain or obstacles that the user wishes to avoid.Type: GrantFiled: April 10, 2017Date of Patent: February 19, 2019Assignee: AGJUNCTION LLCInventors: Eran D.

Patent number: 8245517Abstract: The system and method of the present invention provides stepping speed control of a gas turbine engine to reliably light-off a gas turbine engine. During starting, the speed of the gas turbine engine is incremented by stepped amounts through the light-off window from a minimum speed value to a maximum speed value, with the speed of the gas turbine dwelling at each stepped value for a period of time before incrementing the speed of the engine to the next stepped level. If the gas turbine engine is stepped through the entire light-off window without success, the controller decreases the speed of the gas turbine engine to the minimum value and begins the process again. The process continues until successful light-off is initiated or until the light-off window is traversed a certain number of times, after which the start process is aborted.Type: GrantFiled: May 19, 2009Date of Patent: August 21, 2012Assignee: Hamilton Sundstrand CorporationInventors: Bing Tong, Timothy J. Sullivan, Paul E. Hilgeman, Tarrence L. Mack
