The invention provides an intelligent network connection vehicle lane changing control method for a heterogeneous traffic flow intersection entrance lane. According to the invention, a virtual lane changing area road section is constructed at the upstream of an entrance lane of an intersection, so that an intelligent network connection vehicle obtains road environment information in advance through vehicle-road wireless communication, and obtains positions of a plurality of vehicles, vehicle speeds, distances between the vehicles and front vehicles and vehicle type information through an intelligent vehicle-mounted unit to construct a vehicle information matrix; further generating an entrance lane vehicle information matrix and a vehicle interval information matrix; the V2X cloud center selects the optimal lane changing interval of the target vehicle after receiving and integrating the entrance lane vehicle information matrix and the vehicle interval information matrix; according to the optimal interval selection result, the intelligent network connection vehicle makes a lane changing decision, and a vehicle lane changing control scheme is generated by adjusting the driving state of one or more vehicles; and the intelligent vehicle-mounted unit controls the vehicle driving state according to the control scheme so as to complete lane changing. According to the method, the driving delay caused by the lane changing behavior of the vehicle in the signal crossing entrance lane in the heterogeneous traffic flow environment is effectively reduced, the adverse effect of the lane changing behavior on the traffic flow operation is relieved, the traffic capacity of the intersection is improved, and the traffic travel is more convenient and faster.

    本发明提出了一种异质交通流交叉口进口道智能网联车换道控制方法。本发明在交叉口进口道上游构建虚拟换道区路段,使得智能网联车通过车‑路无线通讯提前获取道路环境信息,并通过智能车载单元获取多个车辆的所在位置、车辆速度、与前车间距和车辆类型信息构建车辆信息矩阵,进一步生成进口道车辆信息矩阵以及车辆间隔信息矩阵;V2X云中心在接收并整合进口道车辆信息矩阵以及车辆间隔信息矩阵后,选取目标车辆的最优换道间隔;根据最优间隔选取结果,智能网联车辆进行换道决策,通过对一个或多个车辆的行驶状态进行调整,生成车辆换道控制方案;智能车载单元根据控制方案控制车辆行驶状态,从而完成换道。本发明有效降低异质交通流环境下信号交叉进口道内车辆换道行为所造成的行车延误,缓解换道行为对交通流运行造成的不良影响,提升了交叉口的通行能力,使得交通出行更加方便快捷。
