In this talk we will present the motivations and advantages of highly integrated platforms in the chassis sector. We will discuss a concept for such a platform based on the AUTOSAR architecture. The individual functions to be integrated into the platform are provided by several parties (internal departments/external suppliers). Due to this fact the independent development, test and release of the individual functions must be ensured. Besides the architectural and functional encapsulation of the functions, the biggest challenge poses the assurance of functional safety on the platform (freedom from interference). We will present a solution for these challenges using independently linkable software components. By using the RTE (Runtime Environment) generation date as a synchronization milestone for the software components, a consistently working system is possible while still maintaining almost complete independence for the rest of the development and release process. Freedom from interference, which is crucial for running ASIL rated software components on a mixed criticality platform, is guaranteed with three main concepts: hardware supervision, software encapsulation in time and space, and protected data exchange. These concepts are combined in a way that allows the whole system to reach ASIL D while single components such as the operating System still are rated at QM level. Furthermore we take the view towards multi core processors with advanced safety features and the impact of the multi core capable middleware AUTOSAR 4.0 on the concept we explained earlier in the talk.
