Systematic Derivation of Objective Requirements on Vehicle Steering System

Zusammenfassung

This thesis answers the question how to derive subsystem requirements with respect to given targets at vehicle level and how to evaluate the performance of subsystems and modules at early stages of design and prototyping. It is shown that based on identified subsystem properties the expectable performance of the vehicle is predictable much earlier than vehicle prototypes are available for test drives.
