Abstract[English]
System and Method for Controlling a Hydraulic System on a Mobile Machine A system for controlling a hydraulic supply on a mobile machine (60) comprises electronic load sensing and is configured to enter a predictive mode of control in which the pump supply pressure PSP is increased following a determination that a hydraulic consumer has been actuated irrespective of the reported hydraulic load at the time. The control system is arranged to monitor the load sensing pressure whilst operative in a predictive mode of control and to revert to a load sensing based control of the pump supply (66) in dependence on the value and/or rate of change of the load sensing pressure. A corresponding method of controlling a hydraulic system on a mobile machine is also disclosed.[French]
L'invention concerne un système et un procédé de commande d'un système hydraulique sur une machine mobile. Un système de commande d'une alimentation hydraulique sur une machine mobile (60) comprend une détection de charge électronique et est configuré pour entrer dans un mode prédictif de commande dans lequel la pression d'alimentation de pompe PSP est augmentée suite à la détermination du fait qu'un consommateur hydraulique a été actionné indépendamment de la charge hydraulique rapportée au moment. Le système de commande est conçu pour surveiller la pression de détection de charge tout en fonctionnant dans un mode de commande prédictif et pour revenir à une commande, basée sur une détection de charge, de l'alimentation de pompe (66) en fonction de la valeur et/ou du taux de variation de la pression de détection de charge. L'invention divulgue également un procédé correspondant de commande d'un système hydraulique sur une machine mobile.
