| Summary: | 碩士 === 國立交通大學 === 電控工程研究所 === 100 === In the last decades, the in-vehicle communication plays a more and more important role in the development of automotive technology. With the growing of complexity of these systems, the timing performance became harder to be guaranteed and predicted. In this thesis, focuses will be taken on feasible method for monitoring bus utilization and procedure of network node planning based on Controller Area Network (CAN) communication system. CAN is a well-designed communication system with high reliability and security, and effectively support distributed real-time control systems. The common real-time schedulers are time-driven scheduling and priority-driven scheduling. Time-driven scheduling is predictable and deterministic but inflexible and time consuming; on the other hand, priority-driven scheduling is more flexible but unpredictable. As the increasing number of CAN node messages, the schedulability of CAN messages became harder to predict. The method of calculating bus utilization will be presented using on-board CAN node. A new CAN communication node will be designed to meet the requirement of electric vehicles. At the end, an integrated CAN node planning system was created to help network designers to plan new CAN nodes properly.
