Network node designs of hardware system and software system based on in-vehicle FlexRay Bus were put forward. Structure and theory of node’s MCU, communication controller and Bus drive were analyzed. The simplest system of FlexRay Bus node was structured, and main files program, clock program, interruption program, and FlexRay Bus communication program were configured. The operation status of FlexRay Bus protocol was analyzed, and programs of receiving and transmitting data were designed. The experimental system based on MC9S12XF512 was established, and in development environment of CodeWarrior IDE, FlexRay Bus networks nodes communication was accomplished based on TDMA and FTDMA mechanism.
