Original Abstract Submitted
A motor grader having a front frame coupled with a rear frame, supported on front and rear wheels. A controller determines a position of actuators operably coupled with a blade attached to the grader, an articulation angle of the rear frame relative to the front frame, and a front wheel steering angle of the front wheels. The controller determines movement of the front and rear frames based on the articulation angle and the front wheel steering angle as the wheels travel over a ground surface. The controller determines a blade position and blade movement of with respect to the front and rear frames based on the position of actuators, rigid body acceleration of the motor grader, and physical characteristics of the machine assembly. The controller determines a blade trajectory path of the blade based on the movement of the front and rear frames, blade position, and blade movement.
