    Abstract

    Modern vehicles use a variety of data networks to exchange data between their different control modules. These networks operate at different communication speeds to reflect the relative response times of the connected control units. For example, engine control units are connected to a high-speed network while comfort systems such as electric seats are connected to a low speed network. In addition, there are a number of different network operating principles, for example, event-driven and timetriggered. Gateways are required to exchange data between these different vehicle networks. Gateways typically exchange messages between connected networks based solely on the destination and priority of the messages. Such gateways can result in unpredictable message delays depending on the network loading and vehicle operating conditions. The aim of this research is to develop and evaluate a vehicle network gateway model based on a very general and well designed gateway structure from the automotive industry, which takes into account factors such as the purpose of network messages, vehicle operating conditions, network loading, bus topology and message streams. The network gateway model is used to evaluate the relative performance of different gateway configurations.
