In a method for the damping force adjustment of motor vehicles in dependence of output signals of a transmitter arranged at the vehicle body which are processed and are compared with a predetermined threshold value and which produce a signal for changing the damping force when exceeding/dropping below this threshold value, the changes of these output signals are added at equal intervals with respect to time and determined over a measuring period which is considerably larger than the natural period (reciprocal resonance frequency) of the vehicle wheels and are compared with a threshold value which is dependent on the load of the vehicle. A drift-free indication about the damping force adjustment to be selected becomes possible therewith without frequency analysis.

Method for the damping force adjustment of motor vehicles as a function

A method for the damping force adjustment of motor vehicles in dependence on output signals of an acceleration transmitter connected with the vehicle body which are prepared and compared with a predetermined threshold value and which trigger a signal for changing the damping, respectively, spring force when exceeding, respectively, falling below the threshold value. An output signal of an acceleration transmitter rigidly connected with the vehicle body is slidingly determined over a first and a second measuring period, the difference of the two average values are subtracted from one another and are compared with the threshold value. The measuring periods are thereby larger, respectively, smaller than the natural period (reciprocal natural frequency) of the vehicle body.
