Site profile based control system and method for controlling a work implement
First Claim
1. An automatic control system for a work machine for operating at a work site, the work site containing material to be operated on by the work machine, comprising:
- a positioning system operable to determine a relative location of the work machine within the work site and produce a machine position signal;
a site model containing data related to a condition of the material; and
, a controller being coupled to the site model operable to receive the machine position signal and determine a current condition of the material as a function of the position signal and the site model, operable to generate a control signal as a function of the current condition of the material and operable to responsively control the work machine as a function of the control signal.

Abstract
An automatic control system for a work machine includes a positioning system, a site model, and a controller. The work machine operates at a work site containing material to be operated on by the work machine. The positioning system determines a relative location of the work machine within the work site and produces a machine position signal. The site model contains data related to a condition of the material. The controller is coupled to the site model, receives the machine position signal and determines a current condition of the material as a function of the position signal and the site model, and controls the work machine as a function of the current condition of the material.
