  • Publication number: 20160076222
    Abstract: A system for determining an optimized cut location for a work implement includes a position sensor and a controller. The controller is configured to determine the position of a work surface and determine an initial cut location along a path based upon an initial target profile and the initial target profile has an initial cut length longer than an evaluation cut length. The controller is also configured to determine a plurality of potential cut locations along the path, determine a volume of material to be moved for each of the plurality of potential cut locations with the volume of material to be moved being based upon the loading profile, the evaluation cut length, and the position of the work surface. The controller is configured to select that optimized cut location from one of the plurality of potential cut locations for which the volume of material exceeds the material volume threshold.

  • Patent number: 9256227
    Abstract: A system for controlling at least one machine at a work site includes a controller configured to store a map of a boundary of a work area at the work site. The controller determines a first arrival time for a first machine to arrive at the boundary and a second arrival time for a second machine to arrive at the boundary. An arrival interval is determined based upon a difference between the first arrival time and the second arrival time the relative travel speed between the first machine and the second machine is adjusted so that the machines arrive at a desired arrival interval.

  • Patent number: 9234750
    Abstract: A system for automated control of a machine within a work area having a crest includes a first data map and a second data map. At least one sensor system generates operating data indicative of a change in terrain and a controller compares the operating data to the first data map while the machine is within a zone adjacent the crest. If the change in terrain exceeds a threshold, the controller generates an alert command signal. A method is also provided.

  • Patent number: 9228315
    Abstract: A system for modifying a path of operation of a machine includes a position sensor and a controller. The controller stores the path of operation, receives a plurality of position signals as the work implement moves material along the path of operation, and determines the position of the work surface. The controller further determines an amount of material moved based at least in part upon the position of the work surface and modifies parameters used to determine a subsequent path of operation if the amount of material moved exceeds a predetermined amount.

  • Patent number: 9163384
    Abstract: A system for automated control of a machine having a ground engaging work implement includes an implement load sensor system. A controller determines a change in terrain based at least in part upon a change in the load on the ground engaging work implement. If the change in terrain exceeds a threshold, the controller generates an alert command signal. A method is also provided.

  • Patent number: 9014924
    Abstract: A system for determining material characteristics of a material of a work surface includes a position sensor and a controller. The controller stores a first estimate of the material characteristics and utilizes a planning system to determine an expected profile. The expected profile is based at least in part upon the first estimate of the material characteristics. The controller determines an actual profile of the work surface, compares the expected profile to the actual profile, and determines a second estimate of the material characteristics based at least in part upon the difference between the expected profile and the actual profile.

  • Patent number: 9014922
    Abstract: A system for determining a cut location at a work surface includes a position sensor and a controller. The controller stores a desired operating parameter and a final design plane of the work surface and determines an actual profile of the work surface. The controller determines a plurality of target profiles corresponding to different cut locations. The target profiles are based at least in part upon the cut location, a loading profile, slot parameters, and the actual profile of the work surface. The controller further determines an optimized target profile relative to the desired operating parameter and the optimized target profile defines an optimized cut location.

  • Patent number: 9002593
    Abstract: A system for re-orienting a machine during a ripping operation includes a position sensing system, a ripper, and a controller. The system stores a ripping path, determines the position of the machine, and compares the position of the machine to the ripping path. A drawbar pull of the machine is determined, compared to a maximum steering drawbar pull, and the ripper is raised if the machine is positioned greater than a predetermined distance from the ripping path and the drawbar pull exceeds the maximum steering drawbar pull. The machine is re-oriented and the ripper lowered relative to the work surface.

  • Patent number: 8948981
    Abstract: A system for determining a cut location at a work surface includes a position sensor and a controller. The controller stores a final design plane of the work surface and determines an actual profile of the work surface. A plurality of target profiles extending along a path are determined, each corresponding to a cut location. The target profiles are based at least in part upon the cut location, a loading profile, slot parameters, and the actual profile of the work surface. The controller is further configured to determine a lowest cost target profile and the lowest cost target profile defines an optimized cut location. A method is also provided.
