With the increase of the number and the complexity of passenger car ECUs (Electronic Control Units), it needs to design passenger car information integrated control system for sharing information and implementing real-time control between these ECUs. In order to design passenger car information integrated control system, it is necessary to research on its primary models. In this paper, the conceptual model, structural model and control model of passenger car information integrated control system are established and analysed. The conceptual model is composed of in-vehicle bus layer, node layer, message layer, signal layer and control rule layer. In terms of in-vehicle network protocol performance and system application feature, single bus structure, single protocol and multiple buses structure, parallel structure of multiple protocols and multiple buses, and hierarchical structure of multiple protocols and multiple buses are designed. According to the transmission direction and network structure of information flow, the control model of passenger car information integrated control system is classified as centralized control, hierarchical control, distributed control and hybrid control. Based on the function requirements of WG6100ENH model natural gas city bus, the information integrated control system of this vehicle is implemented.
