Abstract
(DE)
Die Erfindung betrifft eine Aktoreinrichtung mit einer elektrohydraulischen Betätigungseinrichtung zur Betätigung zumindest einer hydraulischen Betätigungskomponente, insbesondere in einem Antriebsstrang eines Kraftfahrzeugs mit einer von einem Elektromotor (M) angetriebenen Pumpe und einer Steuereinrichtung (1) mit einem Hauptversorgungspfad (2) zur Versorgung und Steuerung des Elektromotors (M) mittels eines Steuergeräts und einer Leistungselektronik. Um im Falle einer Störung im Hauptversorgungspfad (2) eine Minimalfunktion der hydraulischen Betätigungskomponente zu erhalten, ist ein dem Hauptversorgungspfad (2) parallel angeordneter Nebenversorgungspfad (3) sowie eine Überwachungseinrichtung (8) zur Erkennung einer Störung des Hauptversorgungspfads (2) und Aktivierung des Nebenversorgungspfads (3) bei einer Störung vorgesehen.
(EN)
The invention relates to an actuator device having an electrohydraulic operating device for operating at least one hydraulic operating component, in particular in a drive train of a motor vehicle having a pump driven by an electric motor (M) and a control device (1) with a main supply path (2) for supplying and controlling the electric motor (M) by means of a control unit and a power electronic system. In order to maintain a minimum function of the hydraulic operating component in the event of a fault in the main supply path (2), there are provided a secondary supply path (3) parallel to the main supply path (2) and a monitoring device (8) for detecting a fault in the main supply path (2) and activating the secondary supply path (3) in the event of a fault.

L’invention concerne un dispositif actionneur pourvu d’un dispositif d’actionnement électrohydraulique permettant l’actionnement d’au moins un composant d’actionnement hydraulique, en particulier dans une chaîne cinématique d’un véhicule à moteur, le dispositif actionneur étant pourvu d’une pompe entraînée par un moteur électrique (M) et d’un dispositif de commande (1) pourvu d’un chemin principal (2) d’alimentation permettant l’alimentation et la commande du moteur électrique (M) au moyen d’un appareil de commande et d’une électronique de puissance. L’objet de l’invention est de conserver un fonctionnement minimal du composant d’actionnement hydraulique dans le cas d’une défaillance dans le chemin principal (2) d’alimentation. À cet effet, un chemin auxiliaire (3) d’alimentation est disposé parallèlement au chemin principal (2) d’alimentation et un dispositif de surveillance (8) est destiné à repérer une défaillance du chemin principal (2) d’alimentation et à activer le chemin auxiliaire (3) d’alimentation lors d’une défaillance.
