Patent number: 11878745Abstract: A steering wheel actuator is attached to a steering wheel column. The steering wheel actuator includes a gear assembly for turning a steering wheel on the steering wheel column, a motor for rotating the gear assembly, and an enclosure. A control system in the enclosure controls the motor to automatically steer the vehicle. The control system may receive global navigation satellite system (GNSS) signals from a GNSS antenna and GNSS receiver located in the enclosure and automatically steer the vehicle based on the GNSS signals. The control system also may receive inertial measurement unit (IMU) signals from an IMU located in the enclosure and automatically steer the vehicle based on the IMU signals. The control system also may receive user input signals from a user interface located on the enclosure and automatically steer the vehicle based on the user input signals.Type: GrantFiled: September 15, 2020Date of Patent: January 23, 2024Assignee: AGJUNCTION LLCInventors: Jim Tan, Alan Robert Joughin, Jean-Marie Eichner, Glen Sapilewski, Andreas F.

Patent number: 10579068Abstract: A control system fuses different sensor data together to determine an orientation of a vehicle. The control system receives visual heading data for the vehicle from a camera system, global navigation satellite system (GNSS) heading data from a GNSS system, and inertial measurement unit (IMU) heading data from an IMU. The control system may assign weights to the visual, GNSS, and IMU heading data based on operating conditions of the vehicle that can vary accuracy associated with the different visual, GNSS, and IMU data. The control system then uses the weighted visual, GNSS, and IMU data to determine a more accurate vehicle heading.Type: GrantFiled: October 2, 2017Date of Patent: March 3, 2020Assignee: AGJUNCTION LLCInventors: Tommy Ertbolle Madsen, Glen Sapilewski, Anant Sakharkar, Jean-Marie Eichner, Steven J.

Patent number: 7451030Abstract: A system and method provide for precision guiding of agricultural vehicles along a series of adjacent paths to form rows for cultivating a field. In one aspect of the invention the vehicle is moved along a first path while receiving positioning information from a navigational system (e.g., RTK GPS). This positioning information is stored in a processor and is used by the processor to compute a second path adjacent to said first path by calculating piecewise perpendicular offsets from the first path at multiple locations along the first path. The process is repeated to compute a third and subsequent paths so as to cover the field. Because of the offset process, the field may be covered with paths that have varying curvature along their length, while providing substantially no gaps or overlaps in the coverage of the field.Type: GrantFiled: February 4, 2005Date of Patent: November 11, 2008Assignee: Novariant, Inc.Inventors: Michael Eglington, Michael L. O'Connor, Lars G. Leckie, Glen A. Sapilewski

Patent number: 7225060Abstract: A vehicle control system with user-guided calibration is presented. In one embodiment, a vehicle control system is presented comprising an output device and circuitry operative to provide an output, via the output device, that guides a user through a plurality of calibration steps in a particular order. The circuitry can additionally or alternatively be operative to determine which of the calibration steps, if any, to present as a next calibration step based on whether a given calibration step is successful. Other embodiments are provided, and each of the embodiments can be used alone or in combination with one another.Type: GrantFiled: July 30, 2004Date of Patent: May 29, 2007Assignee: Novariant, Inc.Inventors: Michael L.

Patent number: 6880643Abstract: A land-leveling system that uses the Global Positioning System is provided. The system provides for an earth-moving machine mounted with an antenna that receives GPS signals from the satellites of the Global Positioning System. The earth-moving machine comprises a vehicle attached to a work implement, which is also connected to an actuator. A decision unit mounted on the vehicle sends control signals to the actuator, which controls the elevation of the work implement. These control signals are generated using the signals received from the antenna and the desired grade map. This system has an increased coverage area, more accuracy and round-the-clock operability. The system could be used to carry out all the land-leveling operations viz. surveying, leveling and verifying.Type: GrantFiled: February 6, 2003Date of Patent: April 19, 2005Assignee: Novariant, Inc.Inventors: Kurt R.
