Towards the deployment of a centralized ICT architecture in the automotive domain

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.
