System and method of assisted or automated grain unload synchronization

A system comprising:

• an agricultural harvester including—
• a crop processor for reducing crop material to processed crop,
• an unload conveyor for transferring a stream of processed crop out of the harvester,
• a first electromagnetic detecting and ranging module for detecting the location of a receiving vehicle relative to the agricultural harvester, and
• a second electromagnetic detecting and ranging module for detecting at least one of a fill level and a distribution of processed crop in the receiving vehicle;
• and
• one or more computing devices for—
• receiving first data from the first electromagnetic detecting and ranging module, the first data indicating the location of the receiving vehicle relative to the agricultural harvester,
• receiving second data from the second electromagnetic detecting and ranging module, the second data indicating at least one of a fill level and a distribution of grain in the receiving vehicle, and
• generating automated navigation data based on the first data and the second data, the automated navigation data to automatically control operation of at least one of the agricultural harvester and the receiving vehicle to align the unloading conveyor with the receiving vehicle.
