The invention belongs to the technical field of hybrid electric vehicle energy management, and discloses an HEV energy management method based on a distributed depth deterministic strategy gradient. The method comprises the steps of obtaining state demand information of a hybrid electric vehicle; taking the state demand information as an input quantity, and constructing a return function based ona neural network; constructing a distributed depth deterministic strategy gradient controller based on the return function; training a distributed depth deterministic strategy gradient controller to obtain control action parameters in a stable state; and executing an energy management strategy through the trained distributed depth deterministic strategy gradient controller. The HEV energy management method solves the problems that an HEV energy management method in the prior art cannot efficiently adapt to all types of road working conditions and is poor in real-time performance. The real-timeperformance of the algorithm can be improved to a great extent, and the method is suitable for various road working conditions.
