Abstract: A system for controlling a hydraulic supply on a mobile machine comprises electronic load sensing and is configured to predictively increase the pump supply pressure PSP following a determination that a hydraulic consumer is about to be actuated. The pump supply is increased irrespective of the reported hydraulic load at the time to meet a predicted hydraulic demand of consumer. The control system may revert to a load-sensing-based control of the pump supply after a given time period or in dependence on a predefined operational parameter being met. A corresponding method of controlling a hydraulic system on a mobile machine is also disclosed.

Abstract: A control system for hydraulic supply system which includes electronic load sensing is configured to adjust the pump supply pressure PSP in dependence on a determined rate of increase of a load sensing pressure LSP. Below a threshold value T of the rate of increase of the load sensing pressure LSP, the pump supply pressure PSP is adjusted so that it is higher than the load sensing pressure LSP by a stand-by pressure differential ?Pst. At or above the threshold value T, the pressure differential is increased to include a dynamic pressure differential ?Pdyn in addition to the stand-by pressure differential ?Pst. A method of controlling a hydraulic system is also disclosed.

Abstract: A control system for a mobile agricultural machine having a hydraulic supply system which includes electronic load sensing and headland control assistance is configured to predictively adjust the pump supply when a headland sequence is initiated. The pump supply may be increased irrespective of the reported hydraulic load at the time the headland sequence is initiated to meet a predicted hydraulic demand of the headland sequence. The control system may revert to a load-sensing-based control of the pump supply after a given time period or in dependence on a predefined operational parameter being met. A corresponding method of controlling a hydraulic system on an agricultural mobile machine is also disclosed.
