Abstract
An automatic steering system and method for an articulated work vehicle having a front wheel steering system supported by front wheels at a front frame and a rear frame supported by rear wheels rotatably coupled to the front frame at an articulator. A controller operatively connected to the front wheel steering system and to the articulator adjusts wheels of the front wheel steering system along a path and moves the articulator to direct the rear frame in response to a steering signal. The steering signal directs the vehicle in a minimum turn radius mode or a controlled traffic control mode. In the minimum turn radius mode, the rear wheels do not follow the tracks of the front wheels when making a turn. In the controlled traffic mode the rear wheels follow in same tracks as the front wheels.
