AUTOSAR是汽车制造商和供应商之间的合作伙伴关系。它旨在规范汽车软件体系结构，实现软件和硬件的分离。这种方法使软件更加独立，可维护，可重用等。为了使这个标准可用，还有很多工作要做。本文主要研究AUTOSAR中的汽车软件集成，并将层次调度作为一种使能技术。在这一点上，AUTOSAR组件与其任务没有任何时序关系。这会导致无法预测的运行时行为，只能在集成阶段之后进行分析和验证。我们将讨论如何集成可以在AUTOSAR，与运行时暂时隔离的组件。这使得在组件级别而不是在任务级别进行可扩展性分析成为可能。
AUTOSAR is a partnership between automotive manufactures and suppliers. It aims at standardizing the automotive software architecture and separating software and hardware. This approach makes software more independent, maintainable, reuseable, etc. Still there is much work to do in order for this standard to be usable. This paper focus on automotive software integration in AUTOSAR, with the use of hierarchical scheduling as an enabling technology. At this point, AUTOSAR components do not have any timing relation with its tasks. This causes an unpredictive runtime behavior which can only be analyzed and verified after integration phase. We discuss how integration can be done in AUTOSAR, with runtime temporal isolation of components. This enable schedulability analysis at the level of components rather than at the level of tasks.
