Abstract
This paper proposes a design methodology for SOA (Service-Oriented Architecture) of automotive software systems. The connectedness and autonomous-driving drive the fundamental change of the architecture of automotive systems from individual ECU-based to service-oriented. However, the quality requirements of the automotive software systems are diverse and stringent, including safety and real-time-ness. Therefore, conventional design methods to SOA for Web systems are not directly applicable. The authors propose QDDM4SOA (Quality-Driven Design Methodology) for SOA. In this article, the authors extend the QDDM4SOA to the service-bus of automotive SOA, a key platform component of automotive SOA, and demonstrate the effectiveness of the proposed method by experimenting the prototype systems.
