Abstract: A method for controlling an earthmoving machine and a work implement associated with the earth moving machine is disclosed. The method includes receiving positioning signals from a positioning system associated with the earthmoving machine, the positioning signals indicative of a topography of the work surface. The method further includes determining a profile of the work surface based on the positioning signals and determining if the profile of the work surface includes a bump, the bump having a bump height which is greater than an expected surface height. The method further includes determining a depth adjustment based on the bump height and adjusting the target depth based on the depth adjustment, if the profile of the work surface includes the bump.

Abstract: Automated excavating uses automated dozers and other earthmoving equipment to move material at a worksite. Some areas of the worksite may require that control of the automated dozer revert to manual control, such as a spread zone near a crest. A controller monitors the position of automated dozers and adjusts an operating characteristic of an individual automated dozer so that there are not more dozers in the zone than there are operators to manually control them. The adjustment made may depend on the blade loading of an individual dozer, particularly so that a dozer with a loaded blade is not brought to a complete stop, which may cause undue wear on the dozer when re-starting.

Abstract: Automated excavating uses automated dozers and other earthmoving equipment to move material at a worksite. When such equipment is required to avoid a temporary obstruction, traverse between work slots, or traverse between work areas, a controller uses information from real-time sensors and contour maps to determine a new route to the destination. The controller also determines in real time whether the proposed route will keep the equipment on terrain with slopes that do not exceed a slope limit set for the mobile excavation machine. If not, the controller re-routes the machine to a new path over terrain with acceptable slopes.
