Abstract
A navigation system aids a driver of a collection vehicle in keeping pace and distance with a lead harvester while collecting grain. The navigation system can be used for any leader-follower vehicle drive formation. A navigation system steers the head vehicle based on a continuously known position and attitude. Navigation data for the lead vehicle is broadcast to a following collection vehicle. A navigation system in the following vehicle processes the lead vehicle navigation data to determine a relative position and attitude. The navigation system in the following vehicle generates steering and speed commands based on the relative position and attitude to automatically drive to a designated target position alongside the lead vehicle. In one example, an artificial oscillation is induced into the target position to more evenly distribute material in the following vehicle.
