| Popis: | FlexRay is a communication bus for automotive applications, designed to ensure high data rates, fault tolerance, and operates on a time cycle, split in static and dynamic segments for event-triggered and time-triggered communications. Therefore, it becomes suitable for hard real-time and safety-critical applications. Furthermore, it enables cyclic and acyclic communication in the static and dynamic segments according to their specifications, ensuring synchronized, error-free communication between transmitters and receivers. One challenge for applying this protocol, however, is the complexity of the task of message scheduling, for which some techniques have already been developed and we explored to show our method. Here, we carried out the analysis for a specific application that deploys the FlexRay bus, through a heuristic method with the support of a computer software to search for the best combination of message scheduling of the entire system. The effectiveness of the proposed approach is demonstrated by a case study performed within the automotive domain. |
