Intelligent pass jump control
First Claim
1. A system for controlling an earthmoving machine and a work implement associated with the earthmoving machine during an earthmoving operation on a work surface, the earthmoving operation including an upper pass and a lower pass, the system comprising:
- a positioning system associated with the earthmoving machine, the positioning system generating position signals indicative of a position of the work surface; and
a controller configured to execute instructions to;
receive the position signals from the positioning system;
store position signals in a pass history;
determine, based on the pass history, an actual profile of the work surface;
determine, based on the actual profile of the work surface in the pass history, existence of a first condition, the first exists when the actual profile of the work surface includes a first volume having a height above a threshold for the upper pass;
determine, based on the actual profile of the work surface in the pass history, existence of a second condition, the second condition exists when the actual profile of the work surface includes a valley having a floor lower than the threshold for the upper pass; and
direct the earthmoving machine to operate based on the lower pass if the first and second conditions exist.

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.

10. A method for control of an earthmoving machine and a work implement associated with the earthmoving machine during an earthmoving operation on a work surface, the earthmoving operation including an upper pass and a lower pass, the method comprising:
-
receiving position signals from a positioning system associated with the earthmoving machine, the position signals indicative of a position of the work surface; storing the positioning signals in a pass history; determining, based on the pass history, an actual profile of the work surface; determining, based on the actual profile of the work surface in the pass history, existence of a first condition, the first exists when the actual profile of the work surface includes a first volume having a height above a threshold for the upper pass; determining, based on the actual profile of the work surface in the pass history, existence of a second condition, the second condition exists when the actual profile of the work surface includes a valley having a floor lower than the threshold for the upper pass; and directing the earthmoving machine to operate based on the lower pass if the first and second conditions exist. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. An earthmoving machine comprising:
-
a prime mover; a work implement for cutting a work surface during an earthmoving operation, the earthmoving operation including at least an upper pass and a lower pass; a positioning system for generating position signals indicative of a position of the work surface; and a controller configured to execute instructions to; receive the position signals from the positioning system; store position signals in a pass history; determine, based on the pass history, an actual profile of the work surface; 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 of the work surface includes a first volume having a height above a threshold for the upper pass; determine, based on the actual profile of the work surface in the pass history, existence of a second condition, the second condition exists when the actual profile of the work surface includes a valley having a floor lower than the threshold for the upper pass; and direct the earthmoving machine to operate based on the lower pass if the first and second conditions are present.
