- the values detected by the acceleration sensor are integrated by means of an integrator, resulting in the absolute velocity v abs of the first element, and the values detected by the displacement sensor are detected by means of a filter differentiated, resulting in the relative velocity v rei between the first and the second element.
- the control system further comprises a control unit which determines a desired damping force F desired of the controllable damper using a control strategy to which input the absolute speed v abs and the relative speed v rei are applied.
- a control strategy in particular for a product of the signal v abs and the signal v rei greater than or equal to 0, the desired damping force F desired is equal to a product of a gain G, the signal v abs and a function that is independent of the absolute velocity v abs and the relative velocity v rel is dependent.
- the first element comprises a seat and the second element comprises a frame to which the seat is connected.
- Acceleration sensors regularly have a so-called offset, which is integrated in the integration of the values detected by the acceleration sensor and results in a drift of the signal of the determined absolute velocity v abs , ie in an error of this signal.

Also the point can correspond to the further point.
