Abstract
Official abstract text for this publication.
The disclosure describes, in one aspect, a system and method for controlling a rotation angle of a blade of a motor grader having a front frame operatively coupled to a rear frame at a point defining an articulation angle between the front and rear frames. The control system includes at least one sensor operatively associated with the blade, at least one sensor operatively associated with a wheel, at least one sensor operatively associated with at least one of the front frame or the rear frame, and a controller operatively coupled to the at least one sensors. The controller is adapted to determine a current position of the blade, determine a wheel steering angle, determine an articulation angle, and control the rotation angle of the blade based in part on the wheel steering angle and the articulation angle.
First claim
Opening claim text (preview).
I claim: 1. A blade control system for a motor grader, the control system comprising: a first sensor adapted to receive a signal indicative of an articulation angle of the motor grader; a second sensor adapted to receive a signal indicative of a wheel steering angle of the motor grader; a controller operatively connected to a blade of the motor grader; the controller configured to: determine the articulation angle from the first sensor; determine the wheel steering angle fr…
