In this paper, a new intelligent scheduling algorithm, which can improve the network utilization rate, had been present based on analyzing the vehicle CAN bus network schedulability in the vehicle CAN bus electrical control system. Through the mathematical modeling of the vehicle CAN bus network control system, simulation modeling of the 3-loop CAN bus system and computer simulation research based on TrueTime, the results proved that the intelligent scheduling algorithm compared with the existing static or dynamic scheduling algorithms could effectively schedule the various data in the vehicle electric control system based on CAN bus, and improve the system performance. The research results have the reference value in the effective algorithm study for the control system of vehicle CAN bus network.
