Abstract

We present an approach for deployment of real-time software in ECU networks enabling AUTOSAR-based design of fault-tolerant automotive systems. Deployment of software in a safety-critical distributed system implies appropriate mapping and scheduling of tasks and messages to fulfill hard real-time constraints. Additional safety requirements like deterministic communication and redundancy must be fulfilled to guarantee fault tolerance and dependability. Our approach is built on AUTOSAR methodology and enables redundancy for compensation of ECU failures to increase fault tolerance. Based on AUTOSAR-compliant modeling of real-time software, our approach determines an initial deployment combined with reconfigurations for remaining nodes at design time. To enable redundancy options, we propose a reconfigurable ECU network topology. Furthermore, we present a concept to detect failed nodes and activate reconfigurations by means of AUTOSAR.
