Implementation of SOME/IP-CAN Gateway in View of Automotive Service Discovery

Today’s vehicles are moving toward a service-oriented architecture (SOA), with many automotive functions implemented as software. Automotive applications are becoming services, and these services will communicate via middleware such as scalable service-oriented middleware over IP (SOME/IP). In future automotive Electrical/Electronic (E/E) architecture, high-level controllers are expected to communicate with each other via middleware and to use controller area network (CAN) to control low-level electronic control units (ECUs). Therefore, communication between SOME/IP, a new service-based automotive protocol, and CAN, a traditional automotive communication protocol, is essential for future in-vehicle networks (IVNs). In this study, we implement and evaluate the performance of a gateway system that supports SOME/IP-CAN communication, including service discovery. Experimental results show that the worst-case end-to-end processing time of converting and routing SOME/IP-CAN messages in our proposed gateway embedded system is measured to be 9.125 ms.
