The invention discloses an automatic driving vehicle passing method and system based on vehicle and road cloud integration complex traffic conditions. The method comprises the steps of planning an optimal driving path based on an initial position and a target position of a target vehicle; when the optimal driving path has the congestion area, re-planning the driving path, and calculating the driving time required to be increased by the newly planned path; comparing the accident removal expected time with the increased driving time; when the accident removal expected time is not greater than the increased driving time, selecting a new planned path for passing; when the accident removal expected time is greater than the increased driving time, selecting an optimal driving path for passing; and when the distance between the target vehicle and the front vehicle is greater than a first safety distance threshold and the distance between the target vehicle and the opposite driving vehicle is greater than a second safety distance threshold, controlling the target vehicle to pass through the blocking area by borrowing the opposite road. The method can solve the problem that the automatic driving vehicle stops or takes over when encountering the congestion area.
本发明公开了一种基于车路云一体化复杂交通路况自动驾驶车辆通行方法及系统,包括:基于目标车辆的初始位置和目标位置规划最优行驶路径;当最优行驶路径出现阻塞区时重新规划行驶路径,计算新规划路径需要增加的行驶时间;将事故解除预期时间与增加的行驶时间进行比对;当事故解除预期时间不大于增加的行驶时间时,选择新规划路径通行;当事故解除预期时间大于所述增加的行驶时间时,选择最优行驶路径通行;当满足目标车辆与前车的距离大于第一安全距离阈值且目标车辆与对向行驶车辆的距离大于第二安全距离阈值时,控制目标车辆借用对向道路通过阻塞区。本发明方法能够解决自动驾驶车辆遇到阻塞区出现车辆停滞或接管的问题。
