Abstract: A method for calibrating a blade of a motor grader is disclosed. The method comprises resting the blade on a ground plane in a first configuration and then a second configuration, calculating coordinates of a left blade tip and a right blade tip of the blade with reference to coordinates of a frame, while the blade being rested on the ground plane in each of the first configuration and the second configuration, determining a pitch offset, a roll offset and a height offset from the coordinates of the left blade tip and the right blade tip of the blade, and transforming the coordinates of the frame to coordinates of the ground plane using the pitch offset, the roll offset, and the height offset. The transforming equalizes height for the left blade tip with respect to the right blade tip as a constant in each of the first and second configurations and the constant determines a cut depth of the blade in the ground.

Abstract: A system for monitoring a position of an implement of a motor grader relative to a frame thereof is provided. The motor grader includes an actuation system to selectively move the implement relative to the frame. The system includes a fiber optic cable extending along at least a portion of the frame, a portion of the actuation system and a portion of the implement. The fiber optic cable is configured to move with the portion of the actuation system and the portion of the implement, and selectively generate signals indicative of a shape thereof. The system further includes a controller in communication with the fiber optic cable. The controller is configured to determine the shape of the fiber optic cable based on the signals received therefrom, and further determine a position of the implement relative to the frame based on the shape of the fiber optic cable.
