This paper addresses how a service-oriented pattern can enable to resolve a number of paradoxes that traditionally are seen as hard to solve in the area of E/E design in the automotive domain. The presented pattern is based on a service-oriented paradigm. This is then extended with explicit requirements on design-time analysis and on run-time capabilities required by the services.

The services are needed to on the one hand being able to be described in a hierarchical way, and on the other hand being able to be implemented in a service-oriented communication paradigm. These two dimensions are essential to understand to both get the capability to resolve the shown paradoxes and to relate possible solutions to existing automotive standards like adaptive AUTOSAR and SOME/IP. A migration strategy is presented based on this analysis.

The concept of vagrant services is introduced and forms an essential part of both solving paradoxes of today and enabling efficient design patterns for tomorrow, including autonomous vehicles and intelligent traffic systems (ITS).
