Service-Oriented Communication for Controller Area Networks

The appearance of high-performance connectivity (e.g. Automotive Ethernet, C2X Communication) will enable seamless integration of cloud-based services into the vehicle's Electric/Electronic (E/E) architecture. This new development poses several challenges regarding in-vehicle communication such as the need for runtime adaptive communication or the establishment of continuous connectivity between functionality hosted in the cloud and on deeply embedded Electronic Control Units (ECUs). These upcoming challenges can be tackled by the introduction of Service-Oriented Communication (SOC) protocols into the vehicle's communication system. For Ethernet a first standard has been defined with AUTOSAR's SOME/IP. However, today's most used automotive communication bus is still the Controller Area Network (CAN) bus. This paper introduces a concept and a first implementation of a service-oriented communication protocol for CAN.
