    Abstract: A steering control system and method for automated steering of work vehicles that adapts to nonlinearities and uncertainties of steering mechanisms including a tolerance control law, a dynamic control law, and a saturation control law selected and executed in real time based on the magnitude of steering angle error, steering mode command, and manual override signal in real time. The dynamic control law includes a dynamic compensator having a double compensation zero, an integral, and a compensation gain, and further includes a deadband compensator and a control signal limiter.

    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: A system, and method of use thereof, that employs short distance communications signals, thereby limiting and localizing the dissemination area for such signals, for interactively coordinating crop material transfer operations between a harvester and a grain transport, including the automated conduct of an unloading operation, including commencement of the actual unloading of the grain through continuation of such unloading to termination of such unloading, which system and method of the present invention employs operating systems in the harvester and grain transport that so operate to become electronically linked to one another to thereafter operate in unison with one another to effect and control the conduct of the crop material transfer operation between the harvester and grain transport, with each of such operating systems having associated therewith a short range communications system for the transmission and receipt at close range of electronic data signals, such operating systems, when appropriately electronically linked to one another, being operable in conjunction with one another to exchange information, to maintain a communications link therebetween, and to automatedly coordinate and effect various activities of the harvester and grain transport as a crop material transfer operation is effected and proceeds.
