Predictive intelligent energy management method and system for hybrid electric vehicle

The invention provides a predictive intelligent energy management method and system for a hybrid electric vehicle, and relates to the technical field of hybrid electric vehicle energy management. Comprising the steps of dynamically obtaining vehicle front working condition data including distance, vehicle speed and gradient information of a future predicted road section, and calculating the average vehicle speed and average gradient of the future predicted road section; based on the average vehicle speed and the average gradient of a predicted road section in the future, the total energy consumed by the system is calculated in combination with the boundary information and the power demand of the whole vehicle, and the target SOC is dynamically predicted in real time in combination with the expected SOC of the vehicle; and on the basis of the current vehicle SOC and the predicted target SOC, a system charging demand is formed, an economic point operation curve corresponding to the system charging demand is sel
