In the article a generic approach to develop an actuator design with regard to vehicle characteristics is presented. The approach is divided into two main parts. Firstly, a systematical proceeding to find a significant parametric model to describe functional actuator properties, which are essential in a virtual development. Subsequently, the second part describes the procedure from vehicle characteristics to system requirements with the help of the parametric models. The feasibility is proven by the exemplarity application on the design of an air spring actuator. A suitable parametric model is estimated with the help of a knowledge management system. The necessary calculation steps from an oscillation rate of the vehicle body, describing a vehicle characteristic, to the static and dynamic stiffness behavior of the actuator are explained. Validating the proceeding by a forward- and backward-oriented calculation, leads to a useable design method for air spring actuators. Further steps will be an execution of the generic approach on other control system actuators, e.g. an active roll stabilization or a vertical damping control actuator. Furthermore, it will be investigated whether the generic approach is applicable for driving assistant systems as well.
