Component Based Communication Middleware for AUTOSAR

Due to market demands and technological progress automotive electronic systems have become highly complex, distributed, and heterogeneous systems. In consequence, costs and time-to-market tend to out-grow spendable budgets, whereas quality seriously suffers. To overcome this situation, automotive manufacturers agreed upon a new standard for their electronic systems—AUTOSAR. In AUTOSAR applications are built in conformance to the component paradigm by assembling prefabricated application components that utilize standardized component middleware. Hence, AUTOSAR compliant systems provide increased reusability, maintainability and thus reduced time-to-market and over-all costs. However, the middleware itself is still a coarse grained layered software architecture that is hard to adapt and to optimize w.r.t. application specific needs. Within this paper we provide an overview on our work on how to apply the component paradigm to the component middleware itself, and how to capitalize on this redesigned middleware architecture by automatically synthesizing custom-tailored, light-weight middleware that still complies to the AUTOSAR standard.
