Abstract

Electronic control units (ECUs) are widely used to improve the comfort and reliability of vehicles. Due to the increasing degree of distribution and interaction of ECUs, many approaches are adopted to design the in-vehicle networks to ensure the stability and reliability of the holistic network, but none of them support the synchronous development of in-vehicle networks and software in ECUs. This paper put forward a model-based approach to design the in-vehicle networks and the software in ECUs with presenting a dependable platform compliant with OSEK/VDX specifications. The paper presents a tool-chain that covers the entire system development life-cycle including system modeling, model transformation, model analysis, network simulation, code generation, document generation and runtime instrumentation. In addition, a case study is presented to demonstrate the application of the approach. The contribution of the approach is threefold. First, the approach applies the theory of model-based design with OSEK/VDX standard in automotive electronics domain, and implements the transformation between SysML models and OSEK/VDX models through an efficient method. Second, the approach presents a method of software co-design among distributed ECUs. Third, the approach bring forward a simulation model for the system models with in-vehicle networks and provides the designer with the simulation results to optimize the design at the early time of the development
