Abstract
The present disclosure relates to methods for operating an injection valve. An example method may include capturing ACTUAL quantities constituted by actuator current or actuator charge and/or actuator voltage continuously during an injection process; reconstructing a dynamic progression of the nozzle-needle stroke of an injection valve on the basis of a model structure for a motion of the nozzle needle of the injection valve, ascertaining the DESIRED quantities constituted by actuator current or actuator charge and/or actuator voltage therefrom, wherein the dynamic progression of the nozzle-needle stroke is reconstructed via a simplified model structure by introduction of at least one discrete measured value pertaining to the injection valve into a basic model of the nozzle-needle motion; comparing the DESIRED quantities with the ACTUAL quantities; and minimizing the difference between the DESIRED quantities and the ACTUAL quantities.
