A digital reconstruction automatic driving centralized road control system comprises a vehicle static database, a vehicle dynamic parameter library, a static road environment map generation module, a dynamic traffic state diagram generation module, a risk control module and a regulation control module. The risk control module is used for establishing a vehicle risk field model according to the vehicle parameters, evaluating the risk field model, if the risk field model exceeds an early warning threshold value, marking the risk field model of the traffic object as a non-entry area, fusing the non-entry area into a drivable area, and replacing the original part, corresponding to the non-entry area, of the drivable area; according to the invention, the risk control model is introduced and can be used as a supplement for path planning, and a high-risk traffic object is marked as a non-entry area, so that the vehicle terminal is far away from the high-risk traffic object as much as possible during path planning, thereby improving the safety of automatic driving of the vehicle terminal and reducing the probability of occurrence of traffic accidents.
一种数字重构的自动驾驶集中式路控系统,包括包括车辆静态数据库、车辆动态参数库、静态道路环境地图生成模块、动态交通状态图生成模块、风控模块以及规控模块;风控模块:根据车辆参数建立车辆风险场模型,并对风险场模型进行评价,若超过预警阈值,则该交通对象的风险场模型标记为不可驶入区域,不可驶入区域融合至可行驶区域内,可行驶区域原先与不可驶入区域对应部分被替换;本发明通过引入风控模型,能够作为路径规划补充,对于高风险的交通对象则标识为不可驶入区域,使得车辆终端在路线规划时,最大可能远离高风险交通对象,从而提高车辆终端自动行驶的安全性,降低交通事故的发生概率。
