METHOD FOR DETERMINING A CURRENT VALUE NECESSARY FOR CHANGING A SWITCHING STATE OF A PRESSURE CONTROL VALVE

摘要

The invention relates to a method for determining a current value necessary for changing a switching state of a pressure control valve (38) in a fuel conveying system (20), wherein the current flowing through the pressure control valve (38) changes from a starting value to a target value and a time course (11) of the current is examined, wherein the value necessary for changing the switching status is reached when the course (11) of the current has a change in pitch, wherein this change is detected through a first time derivative (15) of the current.
