A previous SAE 2001 Congress paper, 'Multiplex Bus progression' introduced the idea of categorizing vehicle serial data protocols into additional areas beyond the traditional SAE Class A, B, and C. This paper will expand on that idea, and provide a 2003 update to the diagnostics, SafetyBus, Mobile Media, and X-by-Wire categories. All existing mainstream vehicular multiplex protocols (approximately 40) are categorized using the SAE convention plus the new groupings. Top contenders will be pointed out along with a discussion of the protocol in the best position to become the industry standard in each category at this time. This paper proposes the idea that at least eight in-vehicle networks may be necessary - mainly on high-end vehicles in the next ten years. These categories include (besides the existing SAE classes) diagnostics, airbag, mobile media, X-by-wire, and wireless. Each area needs its own protocol and one or more networks running that protocol. Sometimes this is for safety reasons, such as with airbags or X-by-wire. But regardless of vehicle function partitioning, we now have distinct classes of signals that will communicate over their own network, or networks (i.e. multiple sub-buses for smart connector).
