The invention is applicable to the technical field of intelligent transportation and provides a vehicle track prediction method. The method comprises the following steps: acquiring history track dataof multiple vehicles in a preset time period, performing preprocessing on the history track data, thus obtaining a time-space diagram sequence corresponding to the history track data, wherein the time-space diagram sequence comprises time-space diagrams respectively corresponding to moments which are sequentially arranged in the preset time period, and each time-space diagram comprises nodes corresponding to at least three vehicles; and inputting the time-space diagram sequence into a trained prediction model to be processed, thus obtaining a corresponding predicted driving track of each vehicle, wherein the prediction model is obtained by training a Long Short-term Memory (LSTM) network on the basis of sample time-space diagrams corresponding to sample track data of multiple sample vehicles in the same time period and a sample driving track corresponding to each sample vehicle. The invention also provides a vehicle track prediction device and terminal equipment, vehicle track prediction precision and flexibility of the prediction model are improved, and robustness is also enhanced, thereby being better applied to manless driving.
