Abstract (en)
[origin: WO2012139851A1] The invention relates to a method for operating a piezo actuator (12) which can be actuated by means of an activation signal. The piezo actuator can be operated in a passive operating mode and in an active operating mode. The piezo actuator (12) is actuated without a functional actuation demand if the piezo actuator (12) is in a passive operating mode.
