@@@@For the problem that controller area network (CAN) bus communication bandwidth is limited in uninhabited aerial vehicle(UAV) flight control computer, according to the information transmission requirement of new distribution flight control computer to internal communications bus, design FlexRay bus node which taken MPC 565 as central processor unit. Hardware design features of the FlexRay bus node, communications controller configuration, communication software research and development are introduced Detailed. Test the FlexRay node’s performance of real time transmission and receiving by simulating the working environment of distributed architecture flight control computer, and verified the experimental results which meet the demand of new distributed flight control computer’s internal communication, also it has laid a solid foundation to solve the bottleneck problem of internal communication of the new distributed UAV flight control computer.
