Abstract: A cross member on a receiving vehicle which is coupled to a following vehicle, is located relative to a leading vehicle. The location of the cross member is tracked during an unloading operation so the leading vehicle avoids the cross member when unloading material into the receiving vehicle.

Abstract: A leading vehicle loads material into a receiving vehicle during an unloading operation. An unloading control system detects and processes stop conditions to automatically stop a material conveyance mechanism when a stop condition arises.

Abstract: A three dimensional grid map is generated to locate a cross member on a receiving vehicle which is coupled to a following vehicle. The location of the cross member is tracked during an unloading operation so the leading vehicle avoids the cross member when unloading material into the receiving vehicle, and so the fill level is more accurately identified.

Abstract: A cross member on a receiving vehicle which is coupled to a following vehicle, is located relative to a leading vehicle. The location of the cross member is tracked during an unloading operation so the leading vehicle avoids the cross member when unloading material into the receiving vehicle.

Abstract: A physical attribute of a receiving vehicle (a receiving vehicle parameter) is located by calculating a vehicle parameter offset value indicative of the location of the receiving vehicle parameter relative to a reference point on a following vehicle, the following vehicle providing propulsion to the receiving vehicle. The vehicle parameter offset value is stored for access during an unloading operation. A leading vehicle automatically accesses the vehicle parameter offset value and unloads material into the receiving vehicle using the vehicle parameter offset value corresponding to the receiving vehicle.

Abstract: A hitch point where a receiving vehicle is coupled to a following vehicle is located relative to a leading vehicle. The trajectory or route of the following vehicle is detected and a dynamic model estimates a location of a receiving area in the receiving vehicle relative to the leading vehicle based on the trajectory or route of the following vehicle and the location of the hitch point relative to the leading vehicle.

Abstract: A physical attribute of a receiving vehicle (a receiving vehicle parameter) is automatically detected by a sensor on a leading vehicle, and a calibration system locates (by calculating a calibrated offset value) the receiving vehicle parameter relative to a reference point on a following vehicle, the following vehicle providing propulsion to the receiving vehicle. The leading vehicle automatically unloads material into the receiving vehicle using the calibrated offset value corresponding to the receiving vehicle.
