The invention provides a vehicle driving track planning method, which comprises the following steps: S1, calculating an obstacle filling path and storing a file, sampling the obstacle filling path and carrying out segmented calculation, and when a vehicle can pass through the obstacle filling path, querying the file by utilizing a segmented calculation result to obtain a first track; s2, directly calculating and solving by adopting an online trajectory optimization method to obtain a second trajectory; and S3, carrying out joint optimization on the first track and the second track to obtain a final planning track. The problems that the global smoothness of trajectory planning is not high, the trajectory planning generation efficiency is low, and the trafficability of a vehicle in a complex environment is not high are solved.

    本发明提供了一种车辆行驶轨迹的规划方法,包括:步骤S1:计算障碍物填充路径并存储文件,对障碍物填充路径进行采样并分段计算,当障碍物填充路径能够通过车辆时,利用分段计算结果,查询文件,得到第一轨迹;步骤S2:采用在线的轨迹优化方法直接计算求解,得到第二轨迹;步骤S3:对第一轨迹和第二轨迹进行联合优化,得到最终规划轨迹。解决了轨迹规划的全局平顺性不强,轨迹规划生成效率低,车辆在复杂环境下的可通过性不高的问题。
