Abstract—As the improvement of vehicle automation technology, it respects high standards in the field of in-vehicle communication. Because of the fast transmission speed and reliability of the FlexRay network, it has become the most popular in-vehicle communication protocol. The topologies of FlexRay is various, including linear, star and hybrid topology structure, it also supports two-channel transmission. On the base of these advantages, the switched FlexRay network is put forward which can extend the system bandwidth and reliability. This paper designs the scheduling algorithm for the switched FlexRay network, and one new method which can precisely compute the value of the worst case response time of DYN messages is presented. The experiments with computer simulations prove the efficiency and improvements of the proposed scheduling algorithm, and the results show that the worst case response time computing method is better than previous methods.

Index Terms—FlexRay, scheduling, static segment, dynamic segment, worst case response time.
