ISO 15765 기반 통합 OBD 프로토콜 변환 알고리즘 및 시스템 개발

Abstract

Today, commercial vehicle is composed of various electronic control units with the power-train and chassis networks. Each of vehicle models from vendors has heterogeneous diagnostics protocols to support many types of electronic control units. In the diagnostics development, such diversity of diagnostic technologies is more increased due to the requirements of new definitions specified for each vehicle model. It increases complexity of diagnostics, while decreases the re-usability of the existing diagnosis-related codes. As a result, development time and costs increased. To reduce aforementioned complexity and to improve re-usability of software, our study is focused on three kinds of the heterogeneous on-board diagnostic protocols which have been already applied to domestic commercial vehicles. In this paper, we propose new software architecture to integrate multiple diagnostic protocols for the ISO 15765 protocol. In addition, we developed light-weight conversion algorithms for resource-restricted embedded environments.
