1. A vehicle comprising: a first vehicle component;a second vehicle component, wherein the second vehicle component is moveable with respect to the first vehicle component in an oscillating manner;at least one actuator arranged between said first and second vehicle components, comprising a control unit and a closed-loop control unit for minimizing a deviation of a real acceleration value of said second vehicle component from an optimum acceleration value by using at least one available spring path,wherein an optimum excursion zA setpoint and an optimum velocity żAsetpoint of the second vehicle component with respect to the ground surface is determinable from the optimum acceleration value {umlaut over (z)}Ssetpoint of said second vehicle component, and can be supplied as a control force signal to said actuator by means of said control unit and said closed-loop control unit,wherein a means for tracking real seat excursion zA of the second vehicle component with regard to the optimum excursion. 2. The vehicle according to claim 1, wherein said first vehicle component is a vehicle cabin floor and said second vehicle component is a vehicle seat component. 3. The vehicle according to claim 1, wherein calculation means is configured to minimize the real acceleration value. 4. The vehicle according to claim 3, wherein, between said calculating means and said actuator, the closed-loop control unit is arranged to match the real seat excursion zA to the optimum excursion zA setpoint of said second vehicle component by outputting a closed-loop control force signal to said actuator. 5. The vehicle according to claim 1, wherein a sum of a closed-loop control force of said closed-loop control unit and a control force of said control unit results in a setpoint force to be applied of said actuator. 6. A method for spring suspending a vehicle component in a vehicle, the vehicle component having first and second vehicle components, the method comprising: oscillating the second vehicle component with respect to the first vehicle component;measuring at least one acceleration measuring value of said first vehicle component with respect to a ground surface;determining an optimum acceleration measuring value of said second vehicle component as a function of the measured acceleration measuring value,minimizing a deviation of a real acceleration value of said second vehicle component from the optimum acceleration measuring value by using at least one available spring path,wherein determining, in said calculating means, an optimum excursion zA setpoint and an optimum velocity setpoint of said second vehicle component with respect to the ground surface from the optimum acceleration value setpoint of said second vehicle component and feeds the determined values as a control force signal to an actuator by means of a control unit; andtracking real seat excursion zA of the second vehicle component associated with a force with regard to the optimum excursion zA setpoint. 7. The method according to claim 6, further comprising determining an ideal trajectory for spring oscillating behavior of said second vehicle component for minimizing the real acceleration value. 8. The method according to claim 6, wherein minimizing the deviation of the real acceleration value matches the real seat excursion zA to the optimum excursion zAsetpoint of said second vehicle component by outputting a closed-loop control force signal to said actuator. 9. The method according to claim 6, wherein the real seat excursion of said second vehicle component is closed-loop controlled to an associated setpoint value as a function of the optimum acceleration value. 10. The method according to claim 6, wherein the optimum acceleration value is adapted to a driving situation of said vehicle.
