Embodiment
[0142] First, use the intelligent network connection to obtain the dynamic traffic information of the target vehicle, plan the vehicle driving route, and convert the planned vehicle driving route into a method flow chart of the vehicle speed requirement;
[0143] Including obtaining OSM map data; extracting and processing road node information; setting road section weights based on real-time traffic information; after inputting the starting point, using path search algorithm to find the way; dynamic update of real-time traffic information; resetting road section weights during driving value and pathfinding; converting path information into acceleration information and other steps.
[0144] After obtaining real-time road traffic information, it is necessary to optimize and solve the local acceleration requirements. Real-time road traffic information can provide information such as the speed of the vehicle in front, the distance of the signal light, and the green light time. In ...

The invention proposes a vehicle energy management method based on intelligent network connection information, which belongs to the technical field of electric vehicle energy management; specifically: first, for a certain target vehicle, use the intelligent network connection to obtain the dynamic traffic information of the vehicle, construct The objective function and constraint conditions; then, under the constraint conditions, the dynamic programming method is used to solve the objective function, and the optimal acceleration a of the target vehicle is obtained; at the same time, the equivalent circuit model of the power battery is built, and the state space equation is set and discretized; Use the extended Kalman filter method to solve the problem, and get the real-time SOC value of the battery as the battery power condition; finally, the optimal acceleration a of the target vehicle and the battery power condition are used as the optimization factors for energy management, and a method based on fuzzy control is used Distribute and manage the power consumption of the power system and non-power system of the electric vehicle; the energy management of the present invention is novel and effective.
Description
technical field [0001] The invention relates to a vehicle energy management method based on intelligent network connection information, and belongs to the technical field of electric vehicle energy management. Background technique [0002] The driving range and battery life of electric vehicles are the key factors restricting the development of electric vehicles; the energy management technology of electric vehicles can effectively improve the economy of use and increase the driving range of electric vehicles. In addition, since the capacity of the power battery is relatively stable, it is difficult to make major technological breakthroughs in the short term, so energy management technology is currently the most effective and practical key technology to increase the mileage of electric vehicles. [0003] At present, the energy management of pure electric vehicles mostly focuses on the energy management and optimization of multiple energy sources, such as the energy managemen...
