Using a weight versus position profile to control automated unloading

An agricultural operation control system for controlling an unloading operation to unload material from a material transfer vehicle to a container, the agricultural operation control system comprising:

• at least one processor;
• a fill profile accessing system configured to access a weight versus position fill profile corresponding to the container;
• and
• a position control system configured to receive a weight signal indicative of a weight of material conveyed from the material transfer vehicle to the container and generate a control signal to control a controllable subsystem on the material transfer vehicle based on the weight signal and based on the weight versus position fill profile.

A material transfer vehicle that transfers material to a container, the material transfer vehicle comprising:

• a controllable subsystem configured to convey the material from the material transfer vehicle to the container;
• a fill profile accessing system configured to access a weight versus position fill profile corresponding to the container;
• and
• a position control system configured to receive a weight signal indicative of a weight of transferred material and generate a control signal to control the controllable subsystem to transfer material to a position in the container based on the weight signal and based on the weight versus position fill profile.
