IEEE 1451 based smart module for in-vehicle networking systems of intelligent vehicles

摘要

As vehicles are become intelligent for convenience and safety of drivers, the in-vehicle networking (IVN) systems and smart modules are essential components for intelligent vehicles. However, there are obstacles for the wide acceptance of the smart modules, Firstly, because it is very difficult to develop the smart module that supports all the existing IVN protocols, the smart module must be independent of the type of networking protocols. Secondly, when the smart module is to be replaced due to its failure, it is necessary to replace the transducer only keeping the original microprocessor and network transceiver. This paper deals with the IEEE 1451 based smart module that describes the digital interface between a network transceiver and a sensor module. Finally, efficacy of the IEEE 1451 based smart module was evaluated on the experimental model.
