Simulation of FlexRay Communication Using C Language

FlexRay possesses many features not depicted in traditional in-vehicle communication specifications. FlexRay focuses on improving the key needs of the in-vehicle communication network, such as speed, flexible data communication, comprehensive topology choices and fault-tolerant computing. The current research on FlexRay is based on special chips having poor flexibility, making it difficult to conduct and improve research in this field. This paper investigates communication control based on C computer language and simulates the communication process on two personal computers. All modules are achieved in this approach, such as parameters capture, data collecting, standard communication frame creating, coding checkout, transmitting stream coding accession and receiving stream decoding, and the validity of the simulative system is verified by experimental testing. This research offers a very useful way for both improving and developing the chip and standard of FlexRay in the future.
