Abstract

The present subject matter relates to a method for operating a valve (18a), especially a fuel injection valve of an internal combustion engine (10) of a motor vehicle. An auxiliary variable (m) is obtained according to an electrical operating variable (u) of an electromagnetic actuator (26, 30) driving a component of the valve (18a), especially a valve needle (28), and is examined for an occurrence of a pre-determined characteristic. A reference variable (mref) is determined according to the auxiliary variable (m), such that the auxiliary variable (m) is modified according to the reference variable (mref) in order to obtain a modified auxiliary variable (mmod), and the modified auxiliary variable (mmod) is examined for the occurrence of the pre-determined characteristic.
