Abstract
Abstract Method suitable for optimizing an operation of a self-guided vehicle. The method includes steps for incorporating a self-guided capability as part of the operation of the vehicle, the operation further including a mapping technique for soliciting information required for vehicle motion from a first to a second predetermined location. The method then requires dynamically assessing a global optimal path referenced to the first and second locations, and dynamically affecting vehicle motion, by actions premised upon re-evaluating the global optimal path in light of instantaneous vehicle motion, by refining the global optical path so that the vehicle can follow a localized path trajectory which optimizes the refined global path.
