Abstract: Systems and methods for providing grade control on a motor grader without the use of masts attached to the blade. Embodiments include a body angle sensor configured to detect movement of a construction machine's body, a front 3D positioning device configured to detect a geospatial position of the construction machine's body within a world space, a drawbar angle sensor configured to detect movement of the construction machine's drawbar, and a blade angle sensor configured to detect movement of the construction machine's blade. Two positions on the blade may be calculated first within a machine space and subsequently within the world space. Movement of at least one articulating connection may be caused based on the blade positions within the world space.

Abstract: 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.
