  • Patent number: 7706948
    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.

  • Publication number: 20100070178
    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.

  • Publication number: 20090276127
    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.

  • Patent number: 7451029
    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.

  • Publication number: 20080269956
    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.

  • Patent number: 7434838
    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.

  • Publication number: 20080249692
    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.

  • Patent number: 7318595
    Abstract: A skid steer vehicle has a chassis with four drive wheels suspended from the chassis that are damped by four damping cylinders. An electronic controller varies the damping of the cylinders in an automatic mode, based on certain operational parameters of the vehicle, and in a manual mode in response to operator selection of a desired degree of suspension damping.

  • Patent number: 7121355
    Abstract: A dozer blade control system controls the position of a bulldozer blade, maintaining the blade at a constant position as the dozer travels through a worksite. The control system monitors the angle of the dozer blade with respect to the earth and when it senses that the dozer blade is tilting, it corrects the dozer blade's position by extending or retracting hydraulic cylinders that couple the dozer blade to the chassis of the crawler-tractor. When the dozer chassis pitches forwards, the blade begins to tilt forward and to drop closer to the ground. The control system senses this forward rotation of the blade and retracts the hydraulic cylinders that couple the blade to the chassis, causing the blade to return to and maintain its original position.
