Abstract
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.
Claims20
A system for automated control of a machine having a ground engaging work implement, comprising:
- an implement load sensor system configured to measure a load on the ground engaging work implement and provide an implement load signal indicative of the load on the ground engaging work implement to a controller;
- the controller configured to:
- receive the implement load signal;
- determine a change in terrain based at least in part upon a change in the load on the ground engaging work implement;
- determine whether the change in terrain exceeds a threshold change in terrain;
- and
- generate an alert command signal if the change in terrain exceeds the threshold change in terrain.
