The effort for the integration of new functionalities in today's vehicles is increasing as the interconnection and verification of the growing amount of heterogeneous and distributed electric control units (ECU's) becomes more difficult. The demand for a new architectural approach that can cope with the increasing complexity and offers possibilities for a smooth integration of future technologies is urgent. Such technologies are drive-by-wire systems or advanced driver assistance systems. This paper extends the previously introduced ICT architecture for future vehicles by the analysis of a possible system, hardware and software architecture and their properties. In addition, a migration path from the current vehicle architecture is suggested and economic impacts of suggested improvements are shown. A short description of differences to AUTOSAR is given. Demonstrators for proof-of-concept and evaluation are also discussed. With this work we have brought the previously described ICT architecture one step closer to the large-scale implementation in the automotive domain.
