AUTOSAR initiative continues to envoy success in the automotive software domain by providing a common framework for efficient software development and by the integration and reuse of software components. However, additional work is needed to consider non-functional properties in the development cycle. Recent release of AUTOSAR has defined a common language to define timing-related information for the automotive embedded system across all development layers. In this paper, we propose an approach to consider the AUTOSAR timing model. Then we aim to transform it to a classical scheduling model in order to apply directly fundamentals scheduling theories for timing analysis. The approach is applied on a realistic case study, a steer-by-wire system.
