Abstract: A method for generating a swath pattern avoiding point rows for a work vehicle to be driven in a region of a field, which region can be described as having a first side boundary and an opposite second side boundary extending divergently between a first and an opposite second end boundary, the method generating a swath pattern including side by side swaths having centerlines that diverge uniformly between the end boundaries, the method also generating a plurality of swath patterns including options for disabling one or more individual rows of an implement for selection by an operator.

Abstract: A computationally efficient method for generating a spiral swath pattern for a region of a field bounded by a convex polygon, the method automatically generating curved portions for the swath pattern having radii of curvature greater than a minimum turning radius based on the minimum turning radius and a definition of the field boundary.

Abstract: A GPS-based vehicle guidance system and a method for automatically guiding a vehicle through and end of a row turn. The present invention provides a method and system that automatically guides the vehicle through an end of row turn without manual control. An algorithm using the minimum turning radius of the vehicle and the rate of change of the vehicle creates a set of interpolated data points resulting in an end of row turn.

Abstract: A method for calculating spiral swath paths in an area with irregular boundaries and providing automatic guidance of a vehicle along the calculated spiral swath paths. A baseline swath path is generated, and at least one adjacent swath path is calculated based on the minimum turning radius of the vehicle and associated implement. An algorithm calculates the continuous spiral swath path by monitoring a position data points at the end point of the previous swath path at the starting point of the at least one adjacent swath path, configuring a radius of curvature for each individual swath path determining the radius of curvature for each swath path and joining the individual swath paths into one continuous spiral swath path.

Abstract: A method for defining, using, and adjusting curved swath patterns and a swath generation apparatus implementing said method for use in an automated vehicle guidance system.

Abstract: The orientation of a self-propelled vehicle or a towed vehicle relative to the direction of travel of the vehicle can be determined by mounting two ground speed sensors on the vehicle. The orientation of the vehicle relative to the direction of travel of the vehicle can be used to correct the error in the location of an implement mounted on the vehicle determined by a GPS system mounted on the vehicle or the vehicle towing the implement due to crabbing of the vehicle as the vehicle travels substantially perpendicular to a significant slope.

Abstract: An automatic guidance system for an agricultural vehicle includes a tractor, a towed implement, an absolute tractor position sensor, a relative implement position sensor, and an electronic control system. The operator inputs the implement geometry and field information into the control system. The control system combines this data with the absolute vehicle position and relative implement position to accurately guide the towed implement through a field.

Abstract: A work vehicle has a transmission controller that is configured to determine the direction of travel of the vehicle based upon the state of the transmission. The transmission controller is also configured to communicate this information to navigation system to assist the navigation system in determining the vehicle's movement. The transmission controller determines the direction of travel based upon looking at the clutch state and the vehicle speed.

Abstract: A GPS-based vehicle guidance system method for providing an integrated display for the operator of a vehicle and provides determining the ideal swath path based on predetermined and user inputted parameters. The method is applied to both manual and automatic modes of operation, and includes the use of an integrated display that clearly indicates whether the system is operating in chase or pull mode of operation with continuous indicators. The method also includes providing guidance to the vehicle operator at the beginning of the process and during end of row turns, to enable the vehicle to align with the predetermined swath paths.

Abstract: A system for automatically moving a stabilizer of a work vehicle is disclosed. A joystick is connected to an electronic controller, which in turn, is connected to valve drivers to drive stabilizer raising and lowering valves. In one mode of operation, the controller is programmed to move the stabilizers up or down at a rate that is proportional to the deflection of the joystick from a neutral position. If the operator holds the joystick in a certain position or range of positions, the controller enters a second mode in which it automatically raises the stabilizers even if the joystick is released. The stabilizer can be placed in a third mode of operation by moving the joystick rapidly back and forth. When the operator does this, the controller is configured to reduce the ramp rate or damping of its response to joystick movement.
