1. A method for controlling (open loop or closed loop) the damping force of an adjustable damper in a motor vehicle having an active or semi-active damping system, the method comprising the steps of:

  • measuring the distance between a wheel and the bodywork of said motor vehicle utilizing distance sensors for generating distance sensor signals (hi);

    forming a difference of said distance sensor signals (hi);

    determining damping velocity signals (Vdl, Vds) from said difference of said distance sensor signals (hi) over a fixed time difference;

    determining the damning velocity (VDK) from said damping velocity signals (Vdl, Vds); and

    , controlling (open loop or closed loop) said damping force in dependence upon the damping velocity (VDK).
