The decision on commonality configurations of a vehicle architecture has to be made in early phase ofvehicular crashworthiness design to achieve the functional feasibility and economic efficiency. In this design phase, neither the hardware is available, nor the classical virtual methods can be applied. To evaluate the design feasibility efficiently, the Solution Space approach is extended to be able to evaluate the entire vehicle architecture. In this dissertation, an approach to identify the vehicle architecture configurations with feasible crashworthiness design and satisfactory commonality is developed and validated.
