AUTOSAR와 MOST 네트워크를 연동하기 위한 응용 수준 게이트웨이 컴포넌트의 설계

As the size and the complexity of automotive software increase rapidly, the use of a standardized software platform becomes mandatory. AUTOSAR is the de facto standard for automotive software platform developed by leading car manufacturers and first-tier suppliers. However, AUTOSAR has limited applicability since it only supports CAN, LIN and FlexRay which are mostly used for vehicle control applications. It does not support the MOST communication protocol that is commonly used for in-vehicle infotainment applications. This prevents AUTOSAR-based control applications from communicating with the infotainment applications. In order to solve the problem, we propose an application-level gateway component that interconnects AUTOSAR and MOST networks. Our gateway allows applications on one network to communicate with applications on the other network even though the applications do not know the protocol of the opposite side network. Moreover, our gateway is designed not to require any extensions or modifications to the AUTOSAR standard. In this paper, we give a detailed design of the internal structure and the protocol conversion mechanism of the gateway.
