Abstract

Es werden ein Verfahren und eine Vorrichtung zur Druckregelung, insbesondere bei einem Common-Rail-System, mit einer mengengesteuerten Hochdruckpumpe und/oder einem Druckabbauventil beschrieben. Mit einem Modell wird ein Druckregler und/oder ein Stellelement eines Druckregelkreises nachgebildet. Das Modell liefert wenigstens ein Signal, das die Störgrößen des Druckregelkreises charakterisiert.

Figure 00000001
A method and a device for pressure control, in particular in a common rail system, with a quantity-controlled high-pressure pump and / or a pressure relief valve are described. A model is used to simulate a pressure regulator and / or an adjusting element of a pressure control circuit. The model delivers at least one signal that characterizes the disturbance variables of the pressure control loop.
