The present invention relates to a method for determining a desired speed of a vehicle (), preferably an autonomous vehicle. The vehicle comprises a shock absorber arrangement (), preferably an hydraulic shock absorber arrangement, having an elastic hysteresis. The method comprises&#x2014;obtaining () a reference value indicative of the energy dissipated by the shock absorber arrangement () in a reference driving condition of a vehicle and&#x2014;determining () a speed of the vehicle for which the value indicative of the energy dissipated by the shock absorber arrangement () in a similar driving condition is expected to fall within a predetermined energy dissipation range, using said reference value.

Method for determining a desired speed of a vehicle

The present invention relates to a method for determining a functional status of a vehicle shock absorber arrangement (). The method determines a difference between force values during compression and expansion of the vehicle shock absorber arrangement (), whereby the shock absorber arrangement () can be determined to be degraded if the difference is below a predetermined threshold.

Method for determining a functional status of a vehicle shock absorber arrangement

An air suspension arrangement arranged to be connected between a vehicle axle and a vehicle chassis of a vehicle includes a flexible bellows having an upper portion connectable to the vehicle chassis of the vehicle, and a bumper stop, wherein the air suspension arrangement further includes a polymer member arranged between the bumper stop and the flexible bellows for connecting the bumper stop to the flexible bellows. A method for manufacturing the air suspension arrangement and a vehicle including such an air suspension arrangement are also provided.
