The invention discloses a vehicle automatic driving assisting method which comprises the following steps: an automatic driving subsystem receives a navigation request and a navigation path and sends the navigation request and the navigation path to an unmanned aerial vehicle, and the automatic driving subsystem starts automatic driving; whether the precision of a navigation map is lower than preset precision or not is judged, if yes, an unmanned aerial vehicle is started, and if not, an automatic driving vehicle executes automatic driving according to the navigation map; after the unmanned aerial vehicle is started, the unmanned aerial vehicle flies to the front of the automatic driving vehicle and sails to a destination according to the navigation path, and meanwhile, 3D point cloud information of a road is collected and returned in real time; and the automatic driving subsystem receives the 3D point cloud information and processes the 3D point cloud information to generate an auxiliary navigation map with the precision not lower than the preset precision, and the automatic driving automobile recognizes and executes automatic driving according to the auxiliary navigation map. Theinvention further discloses a vehicle automatic driving assisting system. The unmanned aerial vehicle is used for collecting the road conditions in real time to generate the navigation map with higherprecision, and more accurate automatic driving of the vehicle is achieved.
本申请公开一种车辆自动驾驶的辅助方法,包括:自动驾驶子系统接收导航请求和导航路径,并发送导航请求和导航路径至无人机,自动驾驶子系统启动自动驾驶;判断导航地图的精度是否低于预设精度,若是,则无人机启动,否则,自动驾驶汽车按照该导航地图执行自动驾驶;在无人机启动后,无人机飞至自动驾驶汽车的前方,并按照导航路径向目的地航行,同时,实时采集和回传道路的3D点云信息;自动驾驶子系统接收3D点云信息,并处理生成精度不低于预设精度的辅助导航地图,自动驾驶汽车识别并按照辅助导航地图执行自动驾驶。本申请还公开了一种车辆自动驾驶的辅助系统。本申请使用无人机实时采集路况生成精度更高的导航地图,实现车辆更精确的自动驾驶。
