The invention relates to a trajectory prediction method and device and a vehicle, and relates to the technical field of automobiles, in particular to the technical field of automobile trajectory prediction. The method comprises the following steps: acquiring a first position sequence feature and a lane segment sequence feature of a to-be-predicted vehicle; the first position sequence feature is used for representing position features of the to-be-predicted vehicle at multiple historical moments; the lane segment sequence features are used for representing the position relationship between the to-be-predicted vehicle and surrounding lane segments; performing attention mechanism operation based on the first position sequence feature and the lane segment sequence feature to obtain a first lane segment fusion feature; and obtaining a prediction track of the to-be-predicted vehicle based on the first lane segment fusion feature. Therefore, the accuracy of track prediction can be improved.
