Abstract
A system for controlling an earthmoving machine is provided. The system includes a positioning system and a controller. The controller is configured to receive the position signals from the positioning system, store the position signals in a pass history, and determine, based on pass history, an actual profile of the work surface. The controller is further configured to determine, based on the actual profile of the work surface in the pass history, existence of a first condition, the first condition exists when the actual profile has a first volume having a height above a threshold for an upper pass, and existence of a second condition, the second condition exists when the actual profile has a valley having a floor lower than the threshold for the upper pass. The controller is configured to direct the earthmoving machine to operate based on the lower pass if the first and second conditions exist.
