Method for controlling an adjustable vibration damper

A method for controlling an adjustable vibration damper that has at least one adjustable damping valve and at least one work chamber connected to a hydraulic device, which comprises a pump with a motor, comprising:

• calculating a resulting supporting force F of the vibration damper that comprises a passive damping force of the at least one adjustable damping valve and an active actuating force of the hydraulic device;
• and
• determining a pump signal and a valve signal for the at least one adjustable damping valve based on an actuating force requirement of a controller unit at the vibration damper;
• wherein the pump signal and the valve signal are determined based on an actuator characteristic diagram which comprises a plurality of characteristic curves for actuating flows I(X) for actuating the adjustable damping valve, and
• wherein a pump characteristic curve is at least tangential to the characteristic curves representing the actuating flows I(X) so that a determination of the pump signal and of the valve signal is made via a point of contact of the pump characteristic curve with a current characteristic curve in combination with the actuating force requirement.
