A Safety Aware Run-Time Environment for Adaptive Automotive Control Systems Jelena

Abstract—As current studies show, in the last couple of years software functionality of modern cars has increased dramatically. This growth will gradually increase the system complexity, because the new functionality is more and more interconnected. To cope with this process, it is necessary to change the current electrics and electronics (E/E) architecture. An adequate run-time environment (RTE) is the heart of such a new E/E architecture and orchestrates the interaction and communication between the components in such systems. Due to high safety requirements of modern driver assistance, the RTE must also provide built-in safety features. This paper analyses these requirements and derives a set of software modules of an RTE that enforce the safety critical behavior of the entire system. The suggested software architecture can act as a blueprint for other run-time environments that deal with similar requirements. The proposed concept has been integrated in the RTE, that is developed in the RACE project1.
