The application of FlexRay bus on Steer-by-wire system

This paper has designed a Steer-by-wire system based on FlexRay bus communication.At first,it introduces the basic characteristics of FlexRay bus;Then it constructs the steering control module and steering execute module,this two modules communicate with each other by FlexRay bus;At last,it completes the hardware and software designs of Steer-by-wire system nodes based on MC9S12XF512 and TJA1080.Experiment showed the FlexRay bus can satisfies the real time and reliability requirements of Steerby -wire system.
