Fault-Tolerant Deployment of Real-Time Software in AUTOSAR ECU Networks

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