US Patent 10138618 Excavator boom and excavating implement automatic state logic

An excavator comprises a control architecture having one or more linkage assembly actuators and one or more controllers. The one or more controllers are programmed to execute instructions. The instructions determine if there is a request to operate the excavator boom and the excavating implement in automatics mode. The instructions also receive target design surface data representing a target design surface of an excavating operation. The instructions further receive an implement position representing a position of the excavating implement relative to the target design surface. The instructions still further receive an implement angle representing an operating angle of the excavating implement relative to the target design surface. The instructions also determine whether the implement position is within an automatics region of the target design surface, wherein the automatics region represents a region on one or both sides of the target design surface.
