Abstract   With development of the vehicle networking technology, intelligent, convenient and efficient vehicle networking applications come into being based on the accurate and real-time vehicle data, consequently, effective monitoring and management of the location, mileage, speed, fuel consumption and other key data of the vehicles are realized, so that the purpose of efficient management, cost reduction,  intelligent operation,  travel convenience and safe driving are achieved. The huge benefit of vehicle networking in fleet management and safety operation has been fully recognized by people. This paper introduces the system design, implementation method and functions of the management system of fleet’s fuel consumption based on vehicle networking data and real-time calculation, including the design and implementation of the data flow, data storage, data analysis,  backstage processing and front-end interface display, etc. This system uses the Kafka cluster for the real-time receiving of vehicles' original data, and uses Jstorm system for real-time processing of vehicles' original data. The backstage of this system realizes each function mainly through the analysis, processing and storage of the vehicles’ data, using the PostgreSQL database, realizes the front-end interface through using JSP and other relevant technology, and introduces ECharts chart to show the data. The  research  results of this topic  achieve many functions,  such as management of vehicles’  information, data quality  statistics of OBD primary data,  filling processing of vehicles’  remaining fuel and the discriminant of vehicles’  fuel events, after testing, these functions can be applied to vehicle networking applications. 
Keywords：vehicle networking; real-time receiving; real-time processing; vehicle data; fuel consumption management
