| 摘要： | The overall approach to performing this study was to develop simulation models of in-vehicle data buses and safety systems and to investigate, through contacts with industry, developments in in-vehicle networking. The assessment modeled the data interfaces for safety-related user services using Optimized Network Engineering Tool (OPNET) simulation environment, developed by MIL 3 Inc., and established the performance of the J1850 and CAN data bus standards under the data load of individual and combinations of safety system devices and other vehicle elements. The computer-based tool, OPNET, provides a software on environment to model and simulate networks and other distributed computer and communication systems such as automotive networks. This study also investigated the fault tolerance reliability of the emerging in-vehicle networks using fault tolerance analysis techniques. Finally, this study investigated the ability of automotive network standards to support internetworking among multiple in-vehicle data buses. The study team also participated in the SAE committee developing the emerging SAE ITS data bus standard. |
