Abstract

A mobile work machine includes a first grade control system that receives a an external reference position signal from a geographic positioning system, and generates blade control signals to control an orientation of a blade in grading a worksite. The mobile work machine also includes a second grade control system that uses blade mainfall and cross slope as well as chassis (or mainframe) mainfall and cross slope to control the orientation of the blade relative to the frame of the work machine to create a planar grade of a desired mainfall and cross slope. When functionality of the first grade control system is interrupted, the mobile work machine automatically switches to using the second grade control system to perform the grading operation, until the interruption to the functionality of the first grade control system is restored.
