The growing complexity of in-vehicle communication networks has made the use of service-oriented architectures such as SOME/IP in place of traditional CAN-based implementations necessary. The design and implementation of a central gateway to enable connectivity between legacy CAN/CAN-FD networks and Ethernet-based SOME/IP communication to enable seamless integration of mixed-protocol electronic control units (ECUs) in future vehicles are described in this paper. A microcontroller-based concept is realized based on an RTOS, where CAN messages are decoded, translated and passed on using the SOME/IP protocol stack. Performance analysis demonstrates the gateway’s capability to offer low latency and high reliability and hence it can be a good solution for future automotive networks.Gateway architecture facilitates real-time communication using task priority and deterministic scheduling capabilities of the RTOS. Scalability is achieved by modular software components such that the inclusion of further protocols or ECUs can be done easily. Security features like authentication and encryption to suit automotive cybersecurity requirements could be potential enhancements.
