The invention belongs to the technical field of vehicle-road cooperation, discloses a vehicle cooperative control method for an emergency vehicle, and solves the problem that local traffic jam is easily caused due to the lack of precise linkage because the driving state of social vehicles around the emergency vehicle is not considered in a traditional scheme. Therefore, the influence on other social vehicles is reduced while the emergency vehicle passing efficiency is guaranteed. According to the scheme, the traffic data information of the emergency vehicle and the social vehicles around the emergency vehicle is obtained in real time, and when it is judged that the emergency vehicle is currently driven on the lane, the dynamic interval of the emergency vehicle is established according to the current lane where the emergency vehicle is located and the current traffic data information of the emergency vehicle; when other social vehicles in the dynamic interval are judged to meet the lane changing condition, lane changing guiding information is sent to the corresponding social vehicles; when the emergency vehicle arrives at the intersection detection area, traffic light control is executed according to the current traffic data of the emergency vehicle, the length of the intersection detection area and the length of the intersection in combination with the current traffic light state; and finally, after the emergency vehicle arrives at a designated position, ending the vehicle-road cooperative control algorithm.
本发明属于车路协同技术领域,其公开了一种面向应急车辆的车辆协同控制方法,解决传统方案中未考虑应急车辆周围的社会车辆的行驶状态,缺乏精准联动性而带来的容易导致局部交通堵塞的问题,从而在保障应急车辆通行效率的同时降低对其它社会车辆的影响。本发明方案中,实时获取应急车辆及其周围的社会车辆的交通数据信息,当判断应急车辆当前在车道上行驶时,根据应急车辆当前所处车道和应急车辆的当前交通数据信息,建立应急车辆的动态区间,并判断处于所述动态区间内的其它社会车辆满足变道条件时,向对应社会车辆发送引导变道信息;在应急车辆到达交叉路口探测区域时,根据应急车辆的当前交通数据、交叉路口探测区域长度、交叉路口长度,结合当前红绿灯状态执行交通灯控制;最后应急车辆到达指定位置后,结束车路协同控制算法。
