automotive software integration
A growing number of networked applications is implemented on increasingly complex automotive platforms with several bus standards and gateways. Together, they challenge the automotive design process. Recent automotive software standards, in particular AUTOSAR that defines a network runtime environment on top of the existing automotive standards, are intended to improve portability and interoperability. AUTOSAR shall replace or extend earlier proprietary software architecture solutions, but it does not yet sufficiently address time and platform modeling and specification. The presentation will give some examples for open issues with respect to performance, timing and interoperability. It will show how recent results in compositional performance analysis can be exploited to analyze such networked systems, and how to apply design space exploration in a complex automotive supply chain. The resulting tools and methods can even be used to optimize the robustness of an architecture which is important to handle updates and extend the lifetime of an architecture
