Abstract
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.
