摘要： An excavator comprises a chassis, an implement, and an assembly comprising a boom, a stick, and a coupling. The assembly is configured to define a heading {circumflex over (N)} and to swing with, or relative to, the chassis about a swing axis S. The stick is configured to curl relative to the boom about a curl axis C. The implement is coupled to a stick terminal point G via the coupling and is configured to rotate about a rotary axis R such that a leading edge of the implement defines a heading Î. An excavator control architecture comprises sensors and machine readable instructions to generate signals representative of {circumflex over (N)}, an assembly swing rate ωS about S, and a stick curl rate ωC about C, generate a signal representing a terminal point heading Ĝ based on {circumflex over (N)}, ωS, and ωC, and rotate the implement about R such that Î approximates Ĝ.

摘要： An excavator includes a chassis, an implement, control architecture, and an assembly to swing with, or relative to, the chassis and including a boom, stick to curl relative to the boom, and coupling between the implement and stick. The implement rotates about an axis R such that a leading edge LE defines a heading Î. The control architecture comprises sensors, actuators, and controllers to utilize sensor signals to generate a LE position relative to a reference based on reference data and map information, utilize sensor implement edge signals and the excavator position relative to the reference and map information to generate a nearest implement edge (NIE) signal indicative of a LE NIE position relative to the reference, and utilize the actuators for divertive implement rotation about R to adjust Î to account for divertive rotation away from an actual or projected overlap of the NIE and reference.
