Abstract
A method of controlling an electro-hydraulic system having an engine driving a variable displacement pump, a hydraulic valve and a hydraulic actuator in order to achieve more efficient engine operation is disclosed. The pressures in the electro-hydraulic system are monitored and commands are received indicating the desired movement of the hydraulic actuator. Based on the pressure and the commands, the operation being performed by the machine is determined and the engine is set to an efficient setting for the particular segment of machine operation.
