Abstract

The present subject matter relates to a method for operating a valve (18a), particularly a fuel injection valve of an internal combustion engine (10) of a motor vehicle. An auxiliary variable (m) is obtained according to at least one electrical operating variable (u) of an electromagnetic actuator (26, 30) driving a component of the valve (18a), particularly a valve needle (28), and is examined for the appearance of a pre-determined characteristic. Further, the method includes determining a reference variable (mref) characterizing an operational mode of the electromagnetic actuator (26, 30), modifying the auxiliary variable (m) according to the reference variable (mref) in order to obtain a modified auxiliary variable (mmod), and examining the modified auxiliary variable (mmod) for the appearance of the pre­determined characteristic.
