Zusammenfassung:In a method for operating an electrohydraulic valve control system of an internal combustion engine, the electrohydraulic valve control system comprising at least one gas exchange valve actuator and a gas exchange valve, which is hydraulically actuated by it, an actuation characteristic is acquired during the operation of the internal combustion engine while the gas exchange valve is being actuated and is compared with a reference actuation characteristic, which describes a nominal characteristic of the gas exchange valve actuator.
