The invention relates to a vehicle trajectory prediction method and device, a server and a storage medium, and the method comprises the steps: receiving trajectory points uploaded by a plurality of vehicles, and obtaining a historical fitting trajectory of each vehicle based on the trajectory points; obtaining a transverse prediction trajectory and a longitudinal prediction trajectory of each vehicle based on the historical fitting trajectory and the variation of the trajectory points; screening out at least two collision risk vehicles with collision risks based on the transverse prediction trajectory and the longitudinal prediction trajectory of each vehicle; the state matrix stability of each collision risk vehicle is calculated in sequence, and the transverse prediction track and the longitudinal prediction track of each collision risk vehicle are corrected according to the state matrix stability. Therefore, the technical problems that in the prior art, adaptability to environment changes is poor, dependence on high-quality driving data is achieved, and sudden road conditions are difficult to deal with are solved.

    本申请涉及一种车辆的轨迹预测方法、装置、服务器及存储介质,其中,方法包括:接收多个车辆上传的轨迹点,并基于轨迹点得到每个车辆的历史拟合轨迹;基于历史拟合轨迹和轨迹点的变化量得到每个车辆的横向预测轨迹和纵向预测轨迹;基于每个车辆的横向预测轨迹和纵向预测轨迹,筛选出存在碰撞风险的至少两个碰撞风险车辆;依次计算每个碰撞风险车辆的状态矩阵稳定性,并根据状态矩阵稳定性修正每个碰撞风险车辆的横向预测轨迹和纵向预测轨迹。由此,解决了相关技术中对环境变化的适应性较差,且依赖于高质量的驾驶数据,且难以应对突发路况的技术问题。
