Abstract
A system for automated movement of a ground engaging blade of a machine includes an acceleration sensor and a roll rate sensor on the blade to indicate a cross slope angular position of the blade. A controller stores a target cross slope and compares the target cross slope to the cross slope angular position. Movement of the ground engaging blade is at least in part based upon a difference between the target cross slope and the cross slope angular position to maintain the ground engaging blade at the target cross slope.

A control system for automated movement of a ground engaging blade of a machine, the ground engaging blade being configured for rotational movement about an axis to define a cross slope of the ground engaging blade, comprising:
- a first sensor disposed on the ground engaging blade configured to provide a measured cross slope signal indicative of a measured cross slope of the ground engaging blade;
- a second sensor disposed on the ground engaging blade configured to provide a roll rate signal indicative of a roll rate of the ground engaging blade;
- and
- a controller configured to:
- store a target cross slope signal indicative of a target cross slope of the ground engaging blade;
- determine the cross slope angular position based upon the measured cross slope signal and the roll rate signal;
- compare the target cross slope to the cross slope angular position;
- generate a command signal at least in part based upon a difference between the target cross slope and the cross slope angular position;
- and
- transmit the command signal to maintain the ground engaging blade at the target cross slope.
A controller implemented method of adjusting a ground engaging blade of a machine, the ground engaging blade having a first sensor configured to provide a measured cross slope signal indicative of a measured cross slope of the ground engaging blade, and a second sensor disposed on the ground engaging blade configured to provide a roll rate signal indicative of a roll rate of the ground engaging blade, comprising:
- storing within a controller a target cross slope signal indicative of a target cross slope of the ground engaging blade;
- determining a cross slope angular position based upon the measured cross slope signal and the roll rate signal;
- comparing the target cross slope to the cross slope angular position;
- generating a command signal within the controller at least in part based upon a difference between the target cross slope and the cross slope angular position;
- and
- transmitting the command signal from the controller to a control system to maintain the ground engaging blade at the target cross slope.
