The invention discloses an automatic driving vehicle turning control system and a method thereof. The system comprises a cloud server, a central gateway, a vehicle-mounted data transmission device, an automatic driving controller, a vehicle drive-by-wire actuator, a map and positioning module, a light rainfall sensor, a camera group and a millimeter wave radar group. According to the method, a cloud-based turning database is adopted, when an automatic driving vehicle needs to turn, an optimal turning strategy is searched and matched in the cloud database and issued to the vehicle, and an automatic driving system of the vehicle smoothly completes turning according to the issued optimal turning strategy and uploads data of a vehicle drive-by-wire actuator during turning to the cloud. Under the condition that driving safety is met, for large-curvature curves and continuous curves, the turning success rate can be greatly increased, the number of times of taking over of a driver is reduced, the driving experience is improved, and even the turning success rate of 100% can be achieved.

    本发明公开了一种自动驾驶车辆过弯控制系统及其方法,系统包括:云端服务器、中央网关、车载数据传输设备、自动驾驶控制器、车辆线控执行器、地图与定位模块、光雨量传感器、摄像头组及毫米波雷达组。本方法采用了基于云端的弯数据库,当自动驾驶车辆需要过弯时,在云端数据库搜索和匹配最优过弯策略下发到本车,本车自动驾驶系统按照下发的最优化过弯策略顺利完成过弯,并上传过弯时车辆线控执行器的数据到云端。在满足驾驶安全的条件下,针对大曲率弯道和连续弯道,本发明可以极大的提高过弯成功率,减少驾驶员接管次数,提升驾驶体验,甚至可以实现100%的过弯成功率。
