| Abstract: | The characteristic of CAN (controller area network) network communication protocol was briefly introduced and a model of CAN communication system for vehicle chassis integrated control system was constructed based on finite state machine theory in the MATLAB/Simulink/Stateflow. The simulation was conducted to investigate the effect of node's priority and transmission rate on communication delay, and then this communication model was applied to 4WS control system. The network communication delay for control system was analyzed. The results show that it is feasible to use this communication model to investigate the effect of communication delay to control system performance. |
