Abstract:
An apparatus and method are provided for operating a motor grader having steerable front wheels and a front and rear frame pivotally connected at an articulation joint. The method includes selecting an automatic articulation mode, and commanding front wheel steering to turn the motor grader, providing a plurality of front wheel steering corrections to an electronic controller, filtering the plurality of front wheel steering corrections using a method for filtering steering corrections based on the constant curve mode, wherein the method generates filtered front wheel steering corrections, and automatically commanding articulation of the front frame relative to the rear frame about the articulation joint in response to the filtered front wheel steering corrections.
