Abstract

A system for changing the damping characteristics of shock absorbers, based on the signals (Xar'(t)) of the relative movements such as the spring deflection velocity, between the vehicle superstructure and wheels, additional signals (Xar"(t)), such as the spring deflection acceleration, are determined. The two signals are logical linked so that the control of a vehicle variable, such as the activation of adjustably designed shock absorbers, is carried out. This makes it possible to change the characteristic of the shock absorber in operating phases of low damping forces of the shock absorber. This feature optionally reduces noise at damping characteristic changes.
