摘要：	This project is one of several performed under the provisions of Section 5117 of the Transportation Equity Act of the 21st Century (TEA-21). The primary objective of this project was to explore the capacity of the Society of Automotive Engineers (SAE) J1939 network. The work performed under the project included: collecting information from the commercial vehicle user, original equipment manufacturer (OEM), equipment supplier, and laboratory research; profiling high-level functional requirements of component electronic control units (ECUs), which were sourced from industry, as well as surveying and interviewing key industry stakeholders; developing the test matrix based on the input from industry and government; developing a hardware-in-the-loop (HIL) heavy-duty vehicle J1939 network simulator; and identifying and estimating the issues related to the implementation of safety related technologies on the J1939 network on heavy-duty commercial vehicles. The network testing conducted for this Task Order demonstrated that the commercial ECUs used in the network testing, that are representative of a generic and complex network on a commercial truck, implemented J1939 well within the standards. The results from the HIL simulator indicate the network appears to have 2.5 to 3 times the capacity currently used by the majority of commercial heavy vehicles in the United States today. This capacity should allow additional networked system controllers to be safely added to the J1939 network such as electronic stability control systems, roll stability control systems and wireless vehicle inspection systems. / NOTE: Final project rept., May 2001-May 2006. / Supplementary Notes: This publication is available in paper copy only.
