US 2019/0161938 A1 · SYSTEM FOR CONTROLLING OPERATION OF A MACHINE

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.
