The invention discloses a control method for energy management of an extended-range electric vehicle based on vehicle speed prediction. The control method comprises the following steps: acquiring historical vehicle speed information based on a vehicle-mounted sensor; a long-short-term memory network vehicle speed prediction model is constructed, and prediction and verification are carried out through the training set and the test set; the obtained historical vehicle speed information is used as input, and the future vehicle speed is predicted; building an engine, a motor, a power battery and a longitudinal dynamic model; the relation between the whole vehicle demand torque and the predicted vehicle speed is constructed; solving a self-adaptive equivalent fuel consumption factor; and solving the minimum amount of equivalent fuel consumption to obtain the torque of the range extender with the optimal control amount, and repeating the steps until the circulation is finished. The future vehicle speed is predicted through the long-short-term memory network, the vehicle running working condition can be predicted in advance, real-time optimization control can be achieved, meanwhile, the equivalent fuel consumption is minimized, the fuel economy and emission performance of the whole vehicle are improved, and the air quality is improved to a certain degree.
