The invention belongs to the field of a traffic intelligent management system, and particularly relates to a motor vehicle intelligent management big data platform system. The motor vehicle intelligent management big data platform system comprises a central platform, an on-vehicle network communication management system, a mobile phone APP end, a license plate identification information acquisition module, a central platform server and a functional module set. The on-vehicle network communication management system performs wireless communication with the central platform. The central platformserver performs data sharing and exchange with the functional module set. The on-vehicle network communication management system comprises a master control chip, a satellite positioning module, a CANbus communication module, a wireless communication module, a storage module and a financial payment module, wherein the satellite positioning module, the CAN bus communication module, the wireless communication module, the storage module and the financial payment module are connected with the master control chip. The motor vehicle intelligent management big data platform system can display road condition traffic value in real time, thereby reproducing an accident process. A vehicle owner can access the central platform, thereby realizing information sharing, and dynamically acquiring information such as vehicle checking. The system can monitor the checking track of the vehicle for analyzing a role breaking behavior. The system is connected with a parking lot through a network, and parkingspace searching can be realized through navigation, thereby realizing reasonable distribution and utilization.
