  • Publication number: 20150354169
    Abstract: A computer-implemented method for determining a cut location for a machine implement is provided. The method may include comparing a target cut volume to a projected cut volume associated with each boundary of a selected bin, designating the cut location as the boundary most closely approximating the target cut volume if both of the projected cut volumes at the boundaries are either greater than or less than the target cut volume, and designating the cut location as an average of the boundaries if the projected cut volumes at the boundaries are greater than and less than the target cut volume.

  • Patent number: 8918302
    Abstract: A sensor calibration system for a mobile machine is disclosed. The sensor calibration system may have a first calibration object positioned at a first worksite location, a second calibration object positioned at a second worksite location, and a plurality of sensors located onboard the mobile machine to detect the first and second calibration objects. The sensor calibration system may also have a controller in communication with the plurality of sensors. The controller may be configured to calibrate at least one of the plurality of sensors when the mobile machine is proximate the first worksite location, and to calibrate at least one other of the plurality of sensors when the mobile machine is proximate the second worksite location.

  • Patent number: 8862423
    Abstract: A sensor calibration system for a mobile machine is disclosed. The sensor calibration system may have a first machine mounted sensor disposed on the mobile machine and configured to sense a characteristic of an offboard object and to generate a corresponding signal, and a second machine mounted sensor disposed on the mobile machine and configured to sense the characteristic of the offboard object and to generate a corresponding signal. The sensor calibration system may also have a controller in communication with the first and second machine mounted sensors. The controller may be configured to compare the characteristic of the offboard object as sensed by the first machine mounted sensor to the characteristic of the offboard object as sensed by the second machine mounted sensor, and to correct subsequent signals received from the first machine mounted sensor based on the comparison.

  • Publication number: 20140012404
    Abstract: A system for determining a cut location for a machine implement is disclosed. The system may have one or more memories that store instructions and one or more processors that are capable of executing the instructions. The one or more processors may be configured to select a first potential cut location for a machine implement to begin modifying a work surface, and determine a profile extending from the selected first cut location to an end location along which the machine implement will travel to modify the work surface. The one or more processors may be further configured to calculate a volume of material that will be moved by the machine implement as it travels along the profile, and select, based on the calculated volume of material, a second potential cut location for the machine implement to begin modifying the work surface.

  • Patent number: 8620535
    Abstract: A control system is disclosed for a mobile excavation machine operating at a worksite. The control system may have a locating device mounted on the mobile excavation machine that is configured to generate a signal indicative of a current position of the mobile excavation machine at the worksite during completion of an excavation plan. The control system may also have a controller in communication with the locating device and the mobile excavation machine. The controller may be configured to autonomously control the mobile excavation machine based on the excavation plan, and to determine a volume of material missed during completion of a first cut of the excavation plan based on the signal. The controller may be further configured to adjust a characteristic of a second cut of the excavation plan based on the volume of material missed during completion of the first cut of the excavation plan.

  • Publication number: 20120299702
    Abstract: A system for determining a position of a machine within a job site comprises at least one position monitoring device configured to collect information indicative of a location of the machine and a processor, communicatively coupled to the at least one position monitoring device. The processor is configured to estimate a location of the machine based on the received information using a first positioning technique. The processor is also configured to determine a first error value associated with the estimated location of the machine and compare the first error value with a threshold error level. If the first error value exceeds the threshold error level, the processor is configured to receive second information indicative of the location of the machine and determine the location of the machine based on the received second information, wherein the location of the machine is determined using a second positioning technique.

  • Publication number: 20100076708
    Abstract: A sensor calibration system for a mobile machine is disclosed. The sensor calibration system may have a positioning device configured to determine a desired sensing location on the mobile machine, a calibration object, and a sensor configured to sense a characteristic of the calibration object from an actual sensing location on the mobile machine and to generate a corresponding signal. The sensor calibration system may also have a controller in communication with the sensor and the positioning device. The controller may be configured to compare the characteristic sensed from the actual sensing location to a known characteristic associated with the desired sensing location, and to determine a difference between the actual sensing location and the desired sensing location based on the comparison. The controller may further be configured to correct subsequent signals generated by the sensor based on the difference.
