The invention discloses a hybrid electric vehicle adaptive energy management strategy construction method in the field of new energy intelligent management. An energy management strategy of the hybrid electric vehicle is formed by a driver module, an MPC and road section selection module, a self-adaptive strategy adjustment module, an LSTM neural network torque compensation module, an SOC tracking module and an SSA-GRU neural network road classification module, and self-adaptive energy management control is achieved for a hybrid power source module. The engine torque of the hybrid electric vehicle is compensated through an LSTM neural network torque compensation module, road classification and partial torque compensation are achieved by combining SSA-GRU neural network road classification and applying multiple neural network algorithms, and especially independent control over the engine torque, the motor torque and the vehicle speed is achieved. All control factors are mutually associated and mutually independent, an instantaneous optimal torque distribution sequence is designed, the problem of poor adaptability of an energy management strategy is effectively solved, and the prediction precision and convergence speed of long and short term driving speed information are high.
