AUTOSAR standard provides a common framework for software development in the automotive domain. It enables to manage the growing of the automotive architecture complexity by facilitating the integration and reuse of software components. However, additional work is needed to enable scheduling analysis and to handle with more timing properties in the system. In this paper, we propose an approach to enable a model transformation of the AUTOSAR timing model to a classical scheduling one. This allows to apply directly fundamentals scheduling theories for timing analysis. Then, we apply our approach through a steering-by-wire case study. Finally, we analyze the results given by the holistic algorithm and those given by a compositional one.
