System and method for controlling a machine
First Claim
1. A system for controlling a machine during an autonomous material moving operation, comprising:
- a terrain sensing system for generating terrain signals indicative of a topography of a work surface;
a position sensing system associated with the machine for generating position signals indicative of a position of the machine;
a ground engaging work implement configured to engage the work surface and move a volume of material; and
a controller configured to;
determine the topography of the work surface based upon the terrain signals;
generate a first target profile based upon the topography of the work surface prior to the autonomous material moving operation;
generate signals to autonomously operate the machine along the work surface and move material based upon the first target profile;
receive a plurality of signals as the machine moves along the work surface, the plurality of signals being associated with a plurality of necessary input conditions;
generate a pause command to pause the autonomous material moving operation based upon an absence of one of the plurality of necessary input conditions, the absence of one of the plurality of necessary input conditions defining a pause condition;
determine the position of the machine based upon position signals from the position sensing system;
determine an estimate of an amount of material being moved by the ground engaging work implement;
generate a second target profile based upon the topography of the work surface after the pause command, the position of the machine after the pause command, and the estimate of the amount of material being moved by the ground engaging work implement; and
generate signals to re-start autonomous movement of the machine along the work surface based upon the second target profile after elimination of the pause condition.

Abstract
A system for controlling a machine during an autonomous material moving operation includes a terrain sensing system, a position sensing system, and a ground engaging work implement. A controller is configured to determine the topography of the work surface, generate a first target profile, generate signals to autonomously operate the machine along a work surface, receive a plurality of signals associated with a plurality of necessary input conditions, and generate a pause command based upon an absence of one of the plurality of necessary input conditions to define a pause condition. The controller may determine the position of the machine, determine an estimate of an amount of material being moved, generate a second target profile, and generate signals to re-start autonomous operation of the machine based upon the second target profile after elimination of the pause condition.
