Workflow and toolchain for developing the automotive software according AUTOSAR standard at a Virtual-ECU

The increasing demand of new functionalities in next generation vehicles, leads to a growth of the complexity level for the E/E automotive systems. On the same way, the automotive software also tends to follow the same pace, so new methods should be adopted to deal with this scenario of complexity. The next generation of automotive embedded software is rapidly migrating to the AUTOSAR standard, which is an architectural composition of software components idealized to establish an open industry standard for the automotive industry. AUTOSAR aims to increase the reuse of these software components, in particular between different vehicle platforms, and between OEMs and suppliers. Inside this development process, software control suppliers are able to check if the system functionalities are attending to the requirements already in preliminary phases, even if the ECU is not yet available. In this paper the authors show the workflow to develop a virtual validation based on the AUTOSAR standard with a Virtual ECU (V-ECU) using a toolchain consisting of dSPACE (SystemDesk, VEOS and TargetLink) and MathWorks (Matlab, Simulink and Stateflow) software. The simulation of the architecture has been realized considering the communication inside a same V-ECU and also between two different V-ECUs considering a distributed architecture. As result, a point-to-point explanation about AUTOSAR methodology is done to show how the process is done.86987525. IEEE International Symposium on Industrial Electronics (ISIE
