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.

摘要： A dual steering system for controlling the steering of a motor grader is disclosed. The first portion of the steering system comprises a steering wheel connected through a hydraulic steering valve to hydraulic right and left steering cylinders, which are connected to the right front tire and left front tire, respectively. Rotation of the steering wheel causes rotation of the front tires. A second portion of the steering system comprises a first button and a second button that are mounted to a control lever. Actuation of the first button sends a first electrical input signal and actuation of the second button sends a second electrical input signal to an electronic control computer. The electronic control computer generates control signals in response to the electrical input signals and transmits these control signals to a plurality of electro-hydraulic actuators. Actuation of an electro-hydraulic actuator by one of the control signals leads to actuation of the right steering cylinder and the left steering cylinder thereby causing rotation of the front wheels of the grader in one of two directions. Thus, the direction of travel of a motor grader can be controlled by one of two steering systems, one of which permits an operator to maintain contact with a control lever while adjusting the steering of the motor grader.
