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.

    本申请涉及一种轨迹预测方法、装置及车辆,涉及汽车技术领域,尤其涉及汽车轨迹预测技术领域。该方法包括:获取待预测车辆的第一位置序列特征和车道段序列特征;所述第一位置序列特征用于表征多个历史时刻的所述待预测车辆的位置特征;所述车道段序列特征用于表征所述待预测车辆与周边车道段的位置关系;基于所述第一位置序列特征和所述车道段序列特征进行注意力机制运算,得到第一车道段融合特征;基于所述第一车道段融合特征,得到所述待预测车辆的预测轨迹。由此,通过本申请可以提高了预测轨迹的准确性。
