Message Optimization based on Scheduling Model for FlexRay Static Segment Application

Xiang-Qi Kong, Yi-Hu Xu, and Yi-Nan X.
Abstract—FlexRay is a high-speed communication protocol with high flexibility and reliability. To identify message optimization of FlexRay static segment, we employed a message optimization scheme based on scheduling model consisting of three steps. First, in order to improve the efficiency of message transmission, a signal packing scheme based on grouping and arrangement method is proposed. Then, to minimize the number of Frame ID (FID) in a FlexRay system, a message scheduling policy with a static slot can be reused by multiple frames. Finally, on the basis of previous steps, scheduling model of static messages frames is described. At the end of this paper, a vehicle chassis system based on FlexRay network is designed. This indicates that the scheduling model can reduce the FID number by 44%, cut down the busload of static by 0.3%, and increase the bandwidth utilization by 12%.

Index Terms—FlexRay, FID multiplexing, static segment, signal packing, scheduling model.
