Design approaches for integrating CAN with emerging time-triggered protocols
Chris Quigley, Peter W. Jones, Ross McMurran, P. Faithfull · 2006
Time triggered network technologies are now entering into automotive electronic architecture designs. At the same time the number of ECUs integrated within a vehicle is growing, mostly integrated using CAN technology. Control applications on the next generation of vehicles will utilise LIN, CAN and FlexRay network technologies. A signal representing a real world physical quantity such as engine speed may traverse across several of these different networks. This paper investigates future requirements for the design of a vehicle’s electrical architecture. Particular attention is given to the mapping of CAN to time triggered protocols for efficient gateway design, Object Oriented Design and the XML expression of a vehicle electronic control system, and the optimisation of the electronics architecture in terms of cost and network utilisation.
