Abstract

A method for setting a predetermined travel of an actuator (1), in particular a piezo-electric actuator (1) for an injector of an injection system is disclosed. According to said method, a first electric state variable (Q) of the actuator (1), which determines the travel of the actuator (1), is set. Said first electric state variable (Q) is set in accordance with the temperature (TAKTOR) of the actuator (1), to avoid temperature-induced fluctuations of the actuator travel.
