The invention relates to the technical field of intelligent driving, in particular to a deep reinforcement learning safety decision-making method for an automatic driving long-tail scene. The method comprises the following steps: matching a topological relation graph in a long-tail knowledge graph to obtain scene similarity, and determining whether an implicit risk element exists in a driving scene of a vehicle based on the scene similarity; determining attribute information of the implicit risk element under the condition of determining that the implicit risk element exists in the driving scene of the vehicle, and determining a space risk index based on the attribute information of the vehicle and the implicit risk element; determining the scene complexity of the driving scene of the vehicle based on the scene similarity and the space risk index; and inputting the attribute information of the vehicle, the attribute information of each road element and the scene complexity into a decision model to obtain a target action output by the decision model, and controlling the vehicle based on the target action. By the adoption of the method, the vehicle driving safety of the vehicle in a complex scene can be improved.
