Abstract
A motor grader including a main frame, an operational frame movable relative to the main frame about a primary joint, and a plurality of hydraulic cylinders configured to adjust a position of the operational frame relative to the main frame, where each cylinder of the plurality of cylinders is movable between an extended position and a retracted position to adjust the length thereof. The motor grader further includes a processor configured to receive a signal indicating a desired cross slope of the operational frame, receive a signal identifying one of the plurality of cylinders as a lead cylinder, determine a desired position of the operational frame that achieves the desired cross slope of the operational frame, estimate a current position of the operational frame by monitoring a length of the lead cylinder, and adjust the position of the operational frame by controlling a follower cylinder of the plurality of cylinders to create the desired cross slope.
