The invention discloses a crossroad efficient passing method based on vehicle-road cooperation. The method comprises the following steps: acquiring position information and speed information of all vehicles in a dispatching area; judging the driving direction of each vehicle according to the position information of each vehicle, and calculating the estimated time when each vehicle arrives at a first intersection in combination with the speed information of each vehicle; counting the estimated time for each vehicle to arrive at the first intersection, and sorting according to the duration to obtain the sequence for each vehicle to pass through the target intersection, that is, the vehicle with the short estimated time for arriving at the first intersection firstly passes through, and the other vehicles pass through in sequence; and calculating to obtain alternative passing time of each vehicle passing through the target intersection, and determining starting time of the next vehicle passing through the first intersection. According to the invention, vehicle-road cooperation is realized from the driving track and the driving state of the vehicle passing through the crossroad, the technical potentials of automatic driving and vehicle-road cooperation are fully exerted, and the travel efficiency and safety of the automatic driving vehicle are improved.

    本发明公开了一种基于车路协同的十字路口高效通行方法,包括:获取调度区内所有车辆的位置信息和速度信息;根据各车辆的位置信息判断各车辆的行驶方向,结合各车辆的速度信息计算得出各车辆到达第一个路口的预计时间;统计各车辆到达第一个路口的预计时间,依据时长大小进行排序,得到各车辆通过目标路口的顺序,即到达第一个路口的预计时间短的车辆先通过,其余车辆依次通过;计算得到各车辆通过目标路口的备选通过时间,决定下一辆车通过第一个路口的起始时间。本发明从车辆通过该十字路口的行驶轨迹以及行驶状态,做到了车路协同,充分发挥了自动驾驶和车路协同技术潜力,提高了自动驾驶车辆的出行高效性和安全性。
