ABSTRACT:
A piezoelectric actuator on an injection valve is controlled by application of a control curve, on which the maximum amplitudes for a current for controlling the actuator are given. A slowly rising or falling charge course at the beginning or end of a charging or discharging process and hence a linearly controllable charge level can thus be achieved over time. An overdriving of the actuator can thus be prevented.
