    摘要: A method for operating a valve actuated with the aid of an actuator, in particular, an injection valve of an internal combustion engine of a motor vehicle, where the actuator is activated using an activation signal characterizing a desired opening duration of the valve. The activation signal characterizing the desired opening duration is corrected as a function of a valve delay time, in order to obtain a corrected activation signal for activating the actuator; the valve delay time representing a temporal deviation between the activation signal and an actual change of an operating state of at least one component of the valve, in particular, of the valve element of an electromagnetic actuator, or of a valve needle.
