Abstract
Over the last forty years, the use of electronic controls within the automotive industry
has grown considerably. In-vehicle network technologies such as the Controller Area
Network (CAN) and Local Interconnect Network (LIN) are used to connect
Electronic Control Units (ECU) together, mainly to reduce the amount of wiring that
would be required if hardwired integration were used.
Modern passenger cars contain many networks, which means that for the
architecture designer, there is an almost overwhelming number of choices on how to
design/partition the system depending on factors such as cost, weight, availability of
ECUs, safety, Electro-Magnetic Compatibility (EMC) etc. Despite the increasing role
played by in-vehicle networks in automotive electrical architectures, its design could
currently be described as a “black art”. Not only is there an almost overwhelming
number of choices facing the designer, but there is currently a lack of a quantifiable
process to aid decision making and there is a dearth of published literature available.
NetGen is a software tool used to design CAN/J1939, LIN and FlexRay
networks. For the product to remain competitive, it is desirable to have novel features
over the competition. This report describes a body of work, the aim of which was to
research in-vehicle network design processes, and to provide an improvement to such
processes. The opportunities of customer projects and availability of customer
information resulted in the scope of the research focusing on the adoption of LIN
technology and whether the adoption of it could reduce the cost and weight of the
target architecture. The research can therefore be seen to address two issues: firstly
the general problem of network designers needing to design in-vehicle network based
architectures balancing the needs of many design targets such as cost, weight etc, and
secondly the commercial motivation to find novel features for the design tool, NetGen. The outcome of the research described in this report was the development of
design processes that can be used for the selection of low cost and weight automotive
electrical architectures using coarse information, such as that which would be easily
available at the very beginning of a vehicle design programme. The key benefit of
this is that a number of candidate networked architectures can be easily assessed for
their ability to reduce cost and weight of the electrical architecture.
