Abstract
In a drive process of a capacitive control element, especially for a fuel injection valve, a charging of a capacitor having a stipulated voltage is transferred during a stipulated charging time, at least partially, to the control element. A deviation of energy transferred to the control element in the charging time from an experimentally determined curve of stipulated, constant energy for the entire temperature range of the control element is corrected in the subsequent drive processes incrementally by a characteristic mapping of the control element voltage and time.
