The working drives of forestry machines are often highly optimized, energy-efficient hydraulic mechanical load sensing (LS) systems. These have the advantage of consumption-based pump control and the ability to control consumers independently of the load. In principle, the system pressure is based on the consumer with the highest load and is increased by a fixed LS pressure difference. Furthermore, hydraulic mechanical LS systems tend to oscillate. In the course of improved electrohydraulic components and the introduction of computerized systems for monitoring the machines, it makes sense to also electrify the controls in the future. Another advantage of electrohydraulic components is the simple adjustment of system parameters, which allows the control system to be adapted to the operator and thus optimize the work process. In a previous project(http://www.fast.kit.edu/mobima/forschung_6725.php), an electrohydraulic on-demand flow control system was developed, which makes it possible both to minimize the principle-related losses due to the LS pressure difference and to improve the control system. The lower energy input in the form of heat, which is caused by throttle losses, can lead to a cooler being avoided and consumption being reduced. The usual vibrations can also be reduced thanks to the controller structure stored in the program. By looking away from the pump and towards the valves, it is possible to further improve the hydraulic systems. By using separate inlet and outlet control, energy consumption can be further reduced in certain load cases. This is the case with active loads, for example. Here, the load becomes the driving variable so that the pump is not required. If the energy input from active loads is high enough, it is even possible to recuperate some of the energy. A hydraulic accumulator can be used for this purpose. By implementing a suitable control system, consumption should be minimized and the control characteristics maintained or even improved.
