Abstract

Die Erfindung betrifft ein Verfahren zur Spannungssollwertberechnung eines piezoelektrischen Elementes als Funktion eines Rail-Druckes, wobei ein Spannungssollwert mittels eines Multiplikators in Abhängigkeit einer Temperatur des piezoelektrischen Elementes korrigiert wird.The invention relates to a method for voltage setpoint calculation a piezoelectric element as a function of a rail pressure, wherein a voltage setpoint by means of a multiplier in dependence a temperature of the piezoelectric element corrected becomes.

Es ist vorgesehen, dass der zu berechnende korrigierte Spannungssollwert (28) aus dem Spannungssollwert (14) durch Multiplikation mit mindestens einem Korrekturwert (Multiplikator (24)) und/oder durch Addition mit mindestens einem Korrekturwert (Summand (26)) gebildet wird.

Figure 00000001
It is provided that the corrected voltage setpoint (28) to be calculated is formed from the voltage setpoint (14) by multiplication with at least one correction value (multiplier (24)) and / or by addition with at least one correction value (summand (26)).
