<p>A method for operating a valve, in particular a fuel injector of an internal combustion engine of a motor vehicle, in which an auxiliary variable is obtained as a function of at least one electrical operating variable of an electromagnetic actuator driving a component of the valve, in particular a valve needle, and in which the auxiliary variable is checked for the presence of a predefinable characteristic. A reference variable which characterizes the operating behavior of the electromagnetic actuator is ascertained, the auxiliary variable is modified as a function of the reference variable to obtain a modified auxiliary variable, and the modified auxiliary variable is checked for the presence of the predefinable characteristic.</p> |
