Abstract: Due to the defects of field bus, such as low communication rate and high cost, a new control system based on TCP/IP protocol was designed to embed control system with Server/Client structure. The communication network system, software structure and control method were described in detail. XML language was used to transfer frame data through TCP/IP Ethernet. Message queue scheduling algorithm and data clustering at memory sharing buffer technology were introduced to enhance the system’s real-time response performance and meet the function of warning and control. The experimental result shows that it adopts industrial Ethernet bus with the advantages of high rate of communication, good compatibility and low cost. This design is a feasible and efficient method for computer aided driving and control system in vehicle.
