The invention provides a vehicle trajectory prediction method of a sparse space-time fusion module, belongs to the technical field of intelligent traffic and automatic driving, and solves the technical problem that a traditional attention mechanism lacks accurate focusing on key interaction features in a dynamic scene. According to the technical scheme, the method comprises the following steps: firstly, acquiring target information from a sensor, and constructing corresponding features by taking the target information as nodes; secondly, lane line and vehicle features are extracted through a sparse space-time attention module combining diffusion convolution and tan-sigmoid; and finally, predicting a vehicle track through a full connection layer. According to the method, the extracted features are subjected to attention enhancement in space and time dimensions by applying diffusion convolution and efficient additive attention, the precision and real-time performance of vehicle trajectory prediction are improved, the driving path of the vehicle can be mastered, and the method is suitable for automatic driving and intelligent traffic systems.
