Communication plays an important role in modern automotive system architecture. In order to optimize the AUTOSAR intra-ECU communication, an approach based on mapping runnable entities is proposed to reduce task switching, and avoid communication data inconsistency and time delay. Taking into account the various communication behaviors of all runnable entities in the current ECU, we provide six extended rules based on AUTOSAR RTE mapping rules to properly group the runnables into the OS tasks. In addition, an equation is given to evaluate the mapping performance. A mapping case of a vehicle control application has been successfully implemented on SmartOSEK OS.
