Abstract:
A guidance system for a mobile machine includes a location determining device for determining a location of the machine, a user interface and a controller. The controller is configured to receive location information from the location determining device, detect a path followed by the machine using the location information, present a plurality of preliminary waypoints to a user via the user interface, receive waypoint information from the user via the user interface indicating one or more selected waypoints corresponding to one or more of the preliminary waypoints, and automatically guide the machine using the one or more selected waypoints. The controller may automatically generate the plurality of preliminary waypoints as the machine traverses the path.
Abstract:
The use of self-powered, autonomous vehicles in agricultural and other domestic applications is provided. The vehicles include a self-propelled drive system, tracks or wheels operatively connected to the drive system, a power supply operatively connected to the drive system, an attachment mechanism for attaching equipment to the vehicle, and an intelligent control operatively connected to the drive system, power supply, and attachment mechanism. The vehicle is configured to connect to the equipment to perform agricultural operations based upon the equipment. Multiple vehicles can be used in a field at the same time. Furthermore, the invention includes the ability to move one or more of the autonomous vehicles from field to field, home to field, or from generally any first location to a second location.

Abstract:
Computer-implemented methods and systems are disclosed for automatically positioning a moving first vehicle relative to a moving second vehicle traveling in a given area. The method includes the steps of: (a) tracking the second vehicle and guiding the first vehicle to attain a given position relative to the second vehicle; and (b) controlling the first vehicle to maintain a generally constant speed such that an operator of the second vehicle can adjust the speed of the second vehicle to correspondingly adjust a relative position of the second vehicle to the first vehicle in a direction of movement of the first and second vehicles, and controlling the first vehicle to maintain a given distance from the second vehicle in a direction generally perpendicular to the direction of movement of the first and second vehicles by tracking the second vehicle.
Abstract:
Methods and apparatus are disclosed for controlling machine configurations. An example method disclosed herein includes identifying a machine configuration, the machine configuration comprising a host machine connected to an auxiliary machine; determining a desired trajectory based on at least one of the host machine turning, a desired work path, or an alignment of the host machine and the auxiliary machine; and controlling steering of the auxiliary machine based on a desired trajectory of the host machine.
Abstract:
A single imaging device collects image data of a storage portion. A container module identifies a container perimeter of the storage portion in at least one of the collected image data. A spout module is adapted to identify a spout of the transferring vehicle in the collected image data. An arbiter determines whether to use the image data based on an evaluation of the intensity of pixel data or ambient light conditions. An alignment module is adapted to determine the relative position of the spout and the container perimeter and to generate command data to the propelled portion to steer the storage portion in cooperative alignment such that the spout is aligned within a central or target zone of the container perimeter.
Abstract:
First imaging device collects first image data, whereas second imaging device collects second image data of a storage portion. A container identification module identifies a container perimeter of the storage portion in at least one of the collected first image data and the collected second image data. A spout identification module is adapted to identify a spout of the transferring vehicle in the collected image data. An image data evaluator determines whether to use the first image data, the second image data, or both based on an evaluation of the intensity of pixel data or ambient light conditions. An alignment module is adapted to determine the relative position of the spout and the container perimeter and to generate command data to the propelled portion to steer the storage portion in cooperative alignment such that the spout is aligned within a central zone or a target zone of the container perimeter.
Abstract:
At least one example embodiment discloses a method of controlling steering of a vehicle. The method includes identifying a reduced-order vehicle model, the reduced-order vehicle model representing a vehicle transfer function in which a least one highfrequency pole is removed. The method further includes generating target closed loop pole locations based on at least one user preference parameter. The method further includes determining calibration parameters that place closed loop poles of a composite system at the target closed loop poles. The composite system in this context includes the reduced-order vehicle model and a steering control system. Finally, the method includes controlling the steering using the steering control system configured using the calibration parameters.
