This contribution will give a broad overview on automated earth moving machinery, especially on excavators. On the basis of a mobile excavator with state-of-the-art flow sharing system, an analysis of the system characteristics is carried out. The Main aspect of this contribution will be the subsystem controls of the hydraulic system. A suitable control strategy is derived from the architecture of the hydraulic system. Thereby, additional safety components like pipe burst and suction valves are analyzed regarding their influence on the system behavior. The developed control strategy is included into the software architecture. Finally, the model-based validation with a synthetic test cycle for multiple axis is used to show the functionality of the developed algorithms. The work of this contribution is part of the joint research project "Bauen 4.0".
