The invention discloses a method for optimizing a driving path of an intelligent network-connected automobile at an intersection without a signal lamp. The method comprises the following steps: an ICV approaches the intersection without the signal lamp; the ICV sends a request message VIR of entering an intersection to a road side unit RSU through V2X communication; the RSU determines a lane Lin where the ICV enters the intersection through the intention information; the RSU predicts the time when the ICV enters the intersection earliest according to the vehicle information on the Lin acquired by the laser radar; the RSU determines a lane conflicting with the ICV route through the Lin; the RSU predicts the intersection occupation time of the vehicles on the lanes; the optimal time for the ICV to enter the intersection is solved; the RSU sends guide information RSC to the ICV; continuously guiding before the ICV enters the intersection; when the ICV passes through the intersection successfully, guiding is ended; according to the invention, the ICV can be effectively guided to safely and efficiently pass through the intersection.
本发明公开了一种无信号灯交叉路口智能网联汽车行驶路径优化方法,包括:ICV临近无信号灯交叉路口;ICV通过V2X通信向路侧单元RSU发送进入路口的请求消息VIR;RSU通过意图信息确定ICV进入路口的车道Lin;RSU通过激光雷达获取的Lin上的车辆信息预测ICV最早进入路口的时间;RSU通过Lin确定与ICV路线冲突的车道;RSU预测这些车道上的车辆占用路口的时间;求出ICV进入路口的最佳时间;RSU将引导信息RSC发送给ICV;在ICV进入路口前持续进行引导;当ICV成功通过路口引导结束;本发明能够有效地引导ICV安全高效地通过路口。
