本发明提供了一种车辆换道行驶控制方法及系统,该方法包括:获取目标公路的分流区内各车辆当前的运动状态信息;基于运动状态信息对分流区内的各车辆进行状态预测,得到各车辆在预设未来时域内的运动状态预测结果;基于各车辆的运动状态预测结果确定目标车辆驶离目标公路的换道行驶策略;其中,目标车辆为分流区内任意需要驶离目标公路的智能车辆;从换道行驶策略中筛选出分流区的交通流运行效率取最大值时对应的最优换道行驶策略,控制目标车辆按照最优换道行驶策略行驶。本发明充分考虑到了目标车辆的换道行驶对整体交通流的影响,兼顾了换道车辆的运行效率,提升了交通流整体运行效率。
The invention provides a vehicle lane changing driving control method and system. The method comprises the steps that current motion state information of all vehicles in a diversion area of a target road is obtained; performing state prediction on each vehicle in the shunting area based on the motion state information to obtain a motion state prediction result of each vehicle in a preset future time domain; determining a lane changing driving strategy of the target vehicle driving away from the target road based on the motion state prediction result of each vehicle; wherein the target vehicle is any intelligent vehicle which needs to drive away from the target road in the diversion area; and screening an optimal lane-changing driving strategy corresponding to the maximum traffic flow operation efficiency of the shunting area from the lane-changing driving strategies, and controlling the target vehicle to drive according to the optimal lane-changing driving strategy. According to the invention, the influence of the lane-changing driving of the target vehicle on the whole traffic flow is fully considered, the operation efficiency of the lane-changing vehicle is considered, and the whole operation efficiency of the traffic flow is improved.
