The invention discloses a method and device for predicting a vehicle driving track and a medium, and the method comprises the steps: building a lane line fitting equation covering a lane line interruption road section when a lost lane line is sensed; solving a coefficient set of the first lane line fitting equation and the second lane line fitting equation based on the coordinates of the starting points and the coordinates of the ending points of the first lane line interruption road section and the second lane line interruption road section so as to obtain a first lane line fitting track and a second lane line fitting track; and adding corresponding coefficients between the coefficient set of the first lane line fitting equation and the coefficient set of the second lane line fitting equation and averaging to solve a coefficient set of a third lane line fitting equation so as to obtain a third lane line fitting track. According to the technical scheme, accurate prediction of the lane line and intelligent control of the vehicle are achieved, and the problem that the vehicle is out of control due to the fact that the lane is lost is solved.

    本发明公开了一种预测车辆行驶轨迹的方法、装置及介质,所述方法包括当感知丢失车道线时,建立覆盖车道线中断路段的车道线拟合方程;基于第一、第二车道线中断路段的起始点的坐标和结束点的坐标求解第一、第二车道线拟合方程的系数集合,从而得到第一、第二车道线拟合轨迹;以及通过将第一车道线拟合方程的系数集合和第二车道线拟合方程的系数集合之间的对应系数相加并求均值求解第三车道线拟合方程的系数集合,从而得到第三车道线拟合轨迹。本发明的技术方案实现了车道线的准确预测和车辆的智能控制,解决了由于车道丢失导致的车辆失控的问题。
