The invention provides an artificial intelligence-based automatic driving vehicle behavior prediction method and system. The method comprises the following steps of: firstly, acquiring multi-mode driving data of a sample automatic driving vehicle and preprocessing the multi-mode driving data; feature extraction is carried out on data of different modals, and weighted fusion is carried out based on a cross-modal attention mechanism; and constructing an initial dynamic graph network model and a traffic participant behavior model, taking traffic participant behaviors as nodes, determining an interaction relationship between the nodes, and dynamically updating the weight of the edge to obtain an updated dynamic graph network model. On the basis of an attention mechanism, attention distribution of the traffic participants to surrounding obstacles is calculated, and a multi-modal feature vector is constructed and input into the dynamic graph network model to obtain updated node features; and constructing a high-level decision model according to the updated node features, and inputting the multi-modal data of the to-be-tested autonomous vehicle into the model to generate a result. According to the invention, by fusing the multi-modal data, the accuracy of behavior prediction of the automatic driving vehicle is improved.
