The invention provides a multipath CAN bus and GPSa data fusion management method of a new energy automobile. The method comprises the following steps: S1: performing data fusion by unifying the data formats of real-time vehicle data obtained by multipath CAN buses and real-time vehicle position data obtained by a vehicle-mounted GPS module; S2: decomposing the fused data into two paths of data by a branching operation, wherein one path of data is used for real-time display, and the other path of data is used for storing; and S3: analyzing a path of data displayed in real time and sending the path of data to a handheld terminal device for display, and sending the stored another path of data to a server for storage and analysis. According to the method, the vehicle data collection and GPS and other information based on the multipath CAN buses are organically combined, a data structure for collectively collecting information is provided, thereby facilitating the storage, analysis and application of the data, the data processing difficulty can be reduced, and the data analysis efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of data collection and transmission, in particular to a new energy vehicle multi-channel CAN bus and GPS data fusion management method. Background technique [0002] With the rapid development of the automobile industry, problems such as energy consumption and environmental pollution have become increasingly prominent. It is of great significance to vigorously develop new energy vehicles that are energy-saving and environmentally friendly, and to improve the automobile industry through Internet technology. The mechanical structure of new energy vehicles such as pure electric vehicles and hybrid vehicles is simpler than that of traditional internal combustion engine vehicles. The controller area network (ControllerArea Network, CAN) communicates with each other. CAN bus is one of the most promising technologies in the field of automation today. It has the advantages of high reliability, real-time and flexibi...
