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.

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.

Abstract: A computer-implemented method for automatically detecting a need for a ripping pass to be performed by a machine along a work surface is provided. The method may include monitoring one or more of machine parameters of the machine and profile parameters of the work surface, determining whether one or more predefined trigger conditions suggestive of the need for the ripping pass are met based on the machine parameters and the profile parameters, and generating a ripping pass request if one or more of the trigger conditions are satisfied.

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.
