Abstract

The invention relates to a vehicle comprising a vehicle component moveable in an oscillating manner with respect to a first vehicle component, and a first measuring means for measuring at least one acceleration measuring value of said first vehicle component with respect to a ground surface, wherein a calculating means is provided for determining an optimum acceleration value of said second vehicle component to be applied at the moment of the presence of the acceleration measuring value, and at least one actuator arranged between the first and second vehicle components, with control and closed-loop control units, for minimizing a deviation of a real acceleration value of said second vehicle component from the optimum acceleration value by using at least one available spring path.
