Performance evaluation of a multiple networked in-vehicle embedded architecture

The paper deals deals with the modelling and the validation of multiple networking computer systems supporting in-vehicle embedded applications. The modelling principle is based on the development of reusable component models with clearly defined interfaces. The building of a whole application model is obtained by integration of these components. This model can therefore be simulated to verify temporal properties and to optimise the implementation. The method is developed and exploited in the context of the CAROSSE project. It is applied to a multiple networked architecture using both CAN and VAN, based on a PSA Peugeot-Citroen application. It has been extended in order to evaluate how a possible use of OSEK/VDX local scheduling with a given configuration of local tasks can influence the performance of the application.
