The invention provides an intersection vehicle passing guiding method in an automatic driving environment. The intersection vehicle passing guiding method comprises the specific steps: carrying out modeling processing on a target intersection; then estimating the time when the vehicle passes through the boundary of the target intersection according to the passing request of the vehicle, and pre-allocating vehicle exit lanes; then judging whether the vehicles have space-time conflicts in the pre-distribution channel or not, and carrying out vehicle conflict resolution by utilizing a method of converting an exit lane and adjusting the passing sequence of the vehicles; and finally, determining a vehicle passing instruction and returning the vehicle passing instruction to the vehicle so as torealize conflict resolution of automatic driving vehicle in intersection. According to the invention, the conflict resolution method for the automatic driving vehicle passing through the target intersection when space-time conflict exists is achieved, the safe passing requirement of the automatic driving vehicle in the intersection is met, powerful technical service support is provided for development of intelligent transportation, automatic driving, automatic control intersection vehicle-road cooperation and the like.

    本发明提供了一种自动驾驶环境下交叉口车辆通过引导方法,具体步骤为:首先对目标交叉口进行模型化处理;然后根据车辆的通过请求预估车辆通过目标交叉口边界的时间,同时对车辆出口道进行预先分配;随后对车辆在预分配通道内是否存在时空冲突进行判断,并利用转换出口道以及调整车辆通过顺序的方法进行车辆冲突解脱;最后确定车辆通过指令并将其返回车辆,从而实现自动驾驶车辆在交叉口内的冲突解脱,本发明实现了自动驾驶车辆经过目标交叉口时存在时空冲突时的冲突解脱方法,满足了自动驾驶车辆在交叉口内的安全通过需求,为智能交通、自动驾驶、自动控制交叉口车路协同等发展提供了有力技术服务支持。
