The invention provides an intelligent network connection hybrid electric vehicle queue hierarchical control method based on SPAT one-way different communication topology. The method comprises the steps that state information of vehicles in a hybrid electric vehicle queue is obtained, and a one-way different communication topology structure of the hybrid electric vehicle queue is determined; sPAT information of a road is obtained, and the threshold range of the target vehicle speed is determined based on the current position of a vehicle i in the hybrid electric vehicle queue and the position of the vehicle i and the position of a front traffic signal lamp; according to the threshold range of the target vehicle speed and the hybrid electric vehicle queue one-way different communication topological structure, an optimal target speed model is constructed, a dynamic model of the hybrid electric vehicle is constructed, and then the optimal target speed is solved; and a DDPG energy management model is constructed, the optimal target vehicle speed is input into the DDPG energy management model to determine the motor optimal torque and the engine optimal torque of the hybrid electric vehicle at the optimal target speed, and a power system of the hybrid electric vehicle is controlled to work according to the engine optimal torque and the motor optimal torque.
