METHOD AND CONTROL UNIT FOR OPERATING A VALVE

摘要

The invention relates to a method for operating a valve (100) that is activated by an actuator (102, 104), in particular an injection valve (100) of an internal combustion engine of a motor vehicle, wherein the actuator (102, 104) is actuated by an actuation signal (I) characterizing a desired opening duration (Top*) of the valve (100). According to the invention, the actuation signal (I) characterizing the desired opening duration (Top*) is corrected as a function of a valve delay time (t11, t2) in order to obtain a corrected actuation signal (Ikorr) for actuating the actuator (102, 104), wherein the valve delay time (t11, t2) represents a temporal deviation between the actuation signal (I) and an actual change to an operating state of at least one component of the valve (100), in particular of the valve element (104) of an electromagnetic actuator or a valve needle (116).
