The invention discloses a system and a method for a networked autonomous vehicle team to carry out lane change gathering in a bottleneck area, and the method comprises the steps: generating a corresponding lane change gathering scheme based on a preceding vehicle type decision, calculating the movement transverse offset of a preceding vehicle, and improving the precision of the movement transverse offset through a cooperative search intelligent optimization algorithm; inputting the impact value of the collision factor and the safety threshold value of the collision impact factor into a collision risk assessment model, judging whether there is a collision risk, and then controlling the networked automatic driving fleet; lagging vehicle types of the target lane are discussed based on the information matrix, and lane changing gathering is completed. The traffic efficiency of the bottleneck area can be improved, and meanwhile driving safety is guaranteed.
本发明公开了一种网联自动驾驶车队在瓶颈区域进行换道集聚的系统及方法,基于前车类型决策生成对应的换道集聚方案,计算前方车辆的运动横向偏移量,并利用协作搜索智能优化算法提高运动横向偏移量的精确度;将碰撞因子的影响数值、碰撞影响因子的安全阈值输入碰撞风险评估模型,判断是否具有碰撞风险,进而控制网联自动驾驶车队;最后基于信息矩阵对目标车道滞后车辆类型进行讨论,完成换道集聚。本发明能提升瓶颈区域的通行效率,同时保障行车安全。
