System and method for detecting a crest

摘要

A system for automated control of a machine having a ground engaging work implement includes an implement load sensor system. A controller determines a change in terrain based at least in part upon a change in the load on the ground engaging work implement. If the change in terrain exceeds a threshold, the controller generates an alert command signal. A method is also provided.

1. A system for automated control of a machine having a ground engaging work implement for moving material along a work surface, comprising:
an implement load sensor system configured to measure a load on the ground engaging work implement indicative of an amount of material being moved by the ground engaging work implement along the work surface and provide to a controller an implement load signal based upon the amount of material being moved by the ground engaging work implement; the controller configured to:
store a threshold change in the implement load signal, the threshold change in the implement load signal being indicative of proximity to a crest;receive the implement load signal;determine a change in the implement load signal;determine whether the change in the implement load signal exceeds the threshold change in the implement load signal; andgenerate an alert command signal if the change in the implement load signal exceeds the threshold change in the implement load signal.
