Abstract

FlexRay is the new generation in-vehicle network protocol that enable fast data rate, reliability and fault-tolerant. It is developed by BMW, DaimlerChrysler, Bosch, Philips and other semiconductor companies. Because of the rapid development of the automotive industry, the need for in-vehicle communication is growing beyond the capability of simple FlexRay network. The idea of switched FlexRay network emerges to adapt the needs of growing capacity. This thesis aims at solving the problems of schedulers design for both simple and switched in-vehicle networks using FlexRay protocol. This thesis presents the corresponding FlexRay protocol specifications and the real-time scheduling theory. Furthermore, the system schedulability and the optimizations of bus configuration are analyzed. Finally, we provide the scheduling algorithms for these two types of networks.
