摘要：
A method for automatically rotating a motor grader to a predetermined articulation angle. The method includes the steps of: providing an electronic controller, a displacement sensor, articulation cylinders, and an input switch; obtaining information from the displacement sensor indicating the present articulation angle of the motor grader; receiving an input signal from the input switch requesting a predetermined articulation angle; and producing a control signal for actuating the articulation cylinders to rotate the motor grader from the present articulation angle to the predetermined articulation angle.
