    Abstract: A steering system for a towable implement includes a steering sensor, an implement steering controller, a steering control valve, a steering cylinder, and an implement steering mechanism that steers the implement. The steering sensor measures, directly or indirectly, the angular position of the steerable wheels of the implement. The implement steering controller processes feedback from the steering sensor and with a desired steering angle, outputs a steering control signal that is input to the steering control valve. The steering control valve controls the flow of hydraulic fluid to the steering cylinder, which, in turn, powers the implement steering mechanism to turn the wheels of the implement. The steering system may be operated in various control modes, such as, a transportation steering mode, a corner and 180 turn steering mode, a swath tracking steering mode, crab steering mode, and a manual steering mode, which allows manual control of the steering system.

    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: A control system and method is provided for controlling the operational configuration of a spout of a harvester being used to perform unload on the go operations with an associated transport vehicle. The velocities of the harvester and transport vehicle and the lateral and longitudinal distances between the harvester and transport vehicle are used to predict future lateral and longitudinal distances between the harvester and transport vehicle. A control signal is issued to a harvester spout control system if either of the predicted lateral distance or longitudinal distance is outside of an associated acceptable range. The harvester spout control system then either shuts off the spout or changes the orientation of the spout in response to the control signal.
