Abstract
Vorrichtung und Verfahren zum Steuern eines Aktors (CP) eines Ventils, insbesondere für einen piezoelektrischen Aktor eines Einspritzventils für eine Brennkraftmaschine, wobei der Aktor (CP) nacheinander auf zwei Ladungszustände geladen wird, die jeweils einer Stellung des Ventils entsprechen. Es wird vorgeschlagen, dass der Aktor (CP) zur Festlegung eines vorgegebenen zeitlichen Öffnungs- und/oder Schließverhaltens des Ventils beim Aufladen und/oder beim Entladen nacheinander auf mindestens drei unterschiedliche Ladungszustände geladen wird, wobei mindestens einer der Ladungszustände einem teilweise geöffneten und teilweise geschlossen Ventil entspricht. Device and method for controlling an actuator (CP) of a valve, in particular for a piezoelectric actuator of an injection valve for an internal combustion engine, wherein the actuator (CP) is loaded successively to two charge states, each corresponding to a position of the valve. It is proposed that the actuator (CP) is loaded successively to at least three different charge states during charging and / or discharging in order to establish a predetermined time opening and / or closing behavior, at least one of the charge states being partially open and partially closed Valve corresponds.
