US Patent 9675008 Unloading arrangement for agricultural harvesting vehicles

An unloading arrangement includes and agricultural harvester and a transport vehicle arrangement. The agricultural harvester includes an unloading conveyance and a wireless transmitter for transmitting information relating at least to a speed and direction of the harvester. The transport vehicle arrangement includes a transport vehicle; a transport implement coupled with the transport vehicle; a sensor arrangement for establishing an angular orientation of the transport implement relative to the transport vehicle; a wireless receiver for receiving the transmitted information from the harvester; and an electrical processing circuit coupled with the sensor arrangement and the wireless receiver. The electrical processing circuit is configured for steering the transport vehicle arrangement in a reverse direction such that the transport implement is positioned at a desired position relative to the unloading conveyance, based upon the sensed angular orientation of the transport implement and the transmitted information received from the harvester.
