Patent number: 11052943Abstract: A control system is configured to receive a first signal indicative of a current position of a vehicle and a second signal indicative of a desired path for the vehicle. The control system is configured to calculate a virtual path between the current position and a target position on the desired path and to output a third signal indicative of curvature command corresponding to an initial curvature of the virtual path to cause a steering control system of the vehicle to adjust a steering angle of the vehicle. The control is also configured to iteratively receive an updated current position, receive any updates to the desired path, calculate an updated target position, calculate an updated virtual path based on the updated current position and updated desired path, and output an updated curvature command corresponding to a respective initial curvature of the updated virtual path as the vehicle travels across a surface.Type: GrantFiled: November 8, 2018Date of Patent: July 6, 2021Assignee: CNH Industrial America LLCInventors: Nathan Eric Bunderson, John Arthur Mitsuru Petersen, Brian Robert Ray

Patent number: 10784841Abstract: A control system for a work vehicle includes a controller, a processor, and a memory that causes the processor to receive, via a sensor assembly, sensor signals and convert the sensor signals into a plurality of entries of a full measurement vector. The memory devices causes the processor to determine a first state vector using IMU Kalman filter, update a first subset of entries the full state vector, determine a second state vector using a spatial positioning Kalman filter, update a second subset of entries the full state vector based on the second state vector, determine a third state vector using a vehicle Kalman filter, update a third subset of entries of the plurality of entries of the full state vector based on the third state vector, and control movement of the work vehicle based on at least one of the first state vector, the second state vector, the third state vector, and the full state vector.Type: GrantFiled: March 8, 2018Date of Patent: September 22, 2020Assignees: CNH Industrial America LLC, Autonomous Solutions, Inc.Inventors: Matthew D. Berkemeier, Jeffrey Lee Ferrin, John Arthur Mitsuru Petersen

Patent number: 10494789Abstract: An electronic control system for a work allows for control of steering despite movement of an implement that may support a load. Control may be based on vehicle position, velocity, acceleration, center of gravity, and heading. A control point is determined despite movement of the load, and may be based upon one or more of roll, yaw, and pitch of the vehicle. The vehicle may be of the type that allows for control only of wheel or track speed and rotational direction. A desired center of gravity is maintained while controlling an error between a desired vehicle trajectory and a determined trajectory in a closed loop manner.Type: GrantFiled: January 6, 2017Date of Patent: December 3, 2019Assignees: CNH Industrial America LLC, Autonomous Solutions, Inc.Inventors: Matthew D. Berkemeier, Jeffrey Lee Ferrin, John Arthur Mitsuru Petersen
