Abstract

The present subject matter describes a method for operating a valve (18a) actuated by means of an actuator (26, 30), in particular a fuel injection valve of an internal combustion engine (10) of a motor vehicle. The actuator (26, 30) is actuated by means of an actuating current (I) having an actuating duration (ET). The actuating duration (ET) is formed as a function of a target value (t2*) for a closing delay time (t2) of the valve (18a), characterizing a time differential between an end (tETl) of the actuating duration (ET) and a closing time point (ts) of the valve (18a).
