Abstract: A system for controlling operation of a machine having a frame supported by ground engaging members and a work implement movably supported by the frame includes a machine position sensor and an implement position sensor to output data pertaining to a position and orientation of the machine and the work implement within a worksite. The system further includes a controller that receives the data output by the machine position sensor and the implement position sensor. The controller computes an amount of gap that is required for alignment of the machine and the work implement with a slot based on the received data. The controller then controls a movement of the ground engaging members for positioning the machine at the computed amount of gap from a cut point located within the slot prior to the work implement entering a cut position for performing a cut within the slot.

The at least one controller may also be configured to track movement of the plurality of virtual tracking features, and update an electronic terrain map of a worksite based on the movement of the plurality of virtual tracking features.

Abstract: A method, system, and non-transitory computer-readable storage medium for calibrating an implement actuation sensor of a machine are disclosed. The method may include calculating a first elevation value of an implement of the machine. The method may include calculating a second elevation value of a ground-engaging device of the machine. The method may include, in response to determining that the machine is spreading, adjusting the second elevation value based on a compaction factor to determine an adjusted second elevation value. The method may further include determining a first elevation difference value based on a difference between the first elevation value and the adjusted second elevation value. The method may further include calibrating the implement actuation sensor based on the determined difference.

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.
