To enable a targeted derivation of vehicle characteristics in early development phases, a subsystem level is required that permits a concept-independent design of the overall vehicle behaviour. This thesis therefore presents a new methodology for the design of ride comfort parameters on the basis of subsystem properties. In addition to the development of a suitable modelling approach, in which the subsystems of the overall vehicle are linked to one another by means of grey-box models without reference to components, the focus is also on its parameterisation and on the integration of the methodology into the development process. Static and dynamic axle test rigs as well as simulations are employed to derive the associated physical-mechanical relationships. The application of the methodology permits a targeted derivation of properties between the overall vehicle, subsystem and component levels in ride comfort, whereby the subsystem level serves as a new reference for the derivation of component properties. Furthermore, the approach allows a property-based preselection of optimal component concepts as well as detailed competitor analyses. This enables a sustainable increase in efficiency in the development process for ride comfort.
