| Zusammenfassung: | The invention describes a device and a method for monitoring a piezoelectric actuator. It is checked whether a discharge time assumes an inadmissible value, whether the voltage at the piezoelectric actuator assumes an inadmissible value and whether a fault signal is present. A short circuit of a battery switch is detected if the three conditions are met. |
