A fuel injection valve is controlled, the valve includes a piezoelectric actuator as the valve member, which opens up or closes a connection to a space arranged downstream, an electric actuating element for actuating the valve member and a prestressing element which prestresses the valve member into a prestressing direction. A sensor element, which is arranged on the same axis as the valve member supplies an output signal to a control unit concerning the forces acting upon the valve member. The control unit acts upon the actuating element by way of an electric excitation, which has a signal course at least approximately inverse to the output signal of the sensor element.
