Crop row sensing on vehicle with multiple, independently steerable axles/wheels

Abstract:

An agricultural machine has a set of front wheels and a set of rear wheels that are independently steerable relative to one another. Distance sensors are mounted to the agricultural vehicle to sense a distance between the front wheels, and the adjacent row crops, and between the rear wheels, and the adjacent row crops. Automatic steering control signals are generated to automatically steer the front wheels, and rear wheels, based upon the sensed distances.
