Abstract
This paper describes a gateway system based on a MOST network for integrating several different automotive network protocols. For transparent data communication among different protocols regardless of the high-level messages and the data format, Pseudo MOST frame was designed based on MOST frame and this pseudo MOST data frame is used as the data carrier. For automotive application, two types of gateways were developed, one board-type gateway and small-sized module-type gateways. One board-type gateway has ethernet port, video port and audio port. Meanwhile, small-sized module-type gateways are developed for video, audio, bluetooth and Flexray, respectively. Experiments with a network system using several small-sized module gateways verified efficient data communication among different network protocols and confirmed the effectiveness of the proposed gateway system for automotive network integration.
