Data Exchange Interfaces in Automotive SOA

Consumer demands in the automotive industry drive the development of complex In-Vehicle Infotainment (IVI) systems, which need to be fully aware of the entire vehicle and its surrounding. The implementation of such advanced scenarios requires enabling data exchange between different host contexts, such as Advanced Driver Assistance Systems (ADAS) and IVI for example. This paper presents an analysis of different communication mechanisms in service-oriented architectures which are used in automotive software development, both for intra-domain and cross-domain communication. Possible approaches for connecting ADAS and IVI hosts are presented, and analyzed in terms of performance and use cases they support.
