Nowadays multiple networking technologies are used in parallel for the in-vehicle networking of electronic control units (e.g. LIN, CAN; FlexRay, MOST, LVDS). Each of these requires specific HW which are not compatible to each other. The used protocols also differ significantly between the systems, e.g. in the addressing of devices and functions. Generally for all suppliers and therefore also specifically for Continental, as a supplier of components equipped with all previously mentioned networking technologies, it can be observed that the differences in usage varies much between the vehicle manufacturers (OEM's). These differences start at the physical layer and end in the application protocols (e.g. VW CAN is not equal to BMW-CAN). The networking of vehicles with the infrastructure is done with additional networking technologies (GPRS, EDGE, UMTS, in future LTE and WLAN (WiFi)). The used protocol is typically the Internet Protocol (IP). For the usage of services from the infrastructure, services of mobile devices with functions in the vehicle respectively, it's necessary to implement complex gateways an application level. From todays point of view are for Continental applications that use high bandwidth and realtime constraints the starting point. To maintain its innovation and technology leadership, the complexities must be mastered. Nowadays the most important topics are the environmental sustainability and especially the energy efficiency, the protection of all traffic participants, as well as the ensured availability of the increasingly complex functions within vehicles. (1) The IP based networking infrastructure and the common principles of communication for distributed functions shall be identical for the involved vehicle manufacturers. Variants shall be minimized. (2) The interoperability with standard IP applications in the infrastructure and on mobile devices must be given. (3) The within SEIS developed, investigated and chosen technologies must not be niche solutions for vehicles. It must be the goal that future developments, technical innovations in the area of networking technologies, middleware and the applications from IT, industry and consumer electronics can be easily reused in vehicles. From Continentals point of view is Ethernet and IP based networking a logical extension of the existing network infrastructure in vehicles. The IP based networking will be installed soon on a broad basis in series vehicles. The base for that is available but future research is necessary in the areas of quality of service and security. The usage is very broad and the applicability for series projects in vehicles was already shown during the project duration.
