The invention provides an intelligent vehicle confluence method and system under heavy traffic flow, and belongs to the technical field of automatic driving vehicle decision systems. A roadside control unit obtains the position and speed of a vehicle, the number of confluence vehicles on a main lane and a ramp and the driving mode of each confluence vehicle, and represents the confluence passing efficiency eta of the vehicles, the total fuel consumption Q consumed by the vehicles during confluence, a driver comfort evaluation index C, and a comprehensive evaluation index S; and the road right switching frequency m when the comprehensive evaluation index S is maximum is determined, and vehicles on the the main lane and the ramp are controlled to converge according to the confluence. According to the method, the road right switching frequency of the lanes during confluence is reduced, the passing efficiency of vehicles at the confluence point is greatly improved, the fatigue feeling of driving operation is reduced, the fuel consumption of the vehicles is reduced, and meanwhile the requirements for comfort and economy are met.
本发明提供了一种重交通流下的智能车辆汇流方法及系统,属于自动驾驶汽车决策系统技术领域。本发明的路侧控制单元获取本车的位置和速度、主道和匝道的汇流车辆数量以及各汇流车辆的驾驶模式,分别表示车辆汇流通行效率η、汇流时车辆多消耗的燃油消耗量Q总以及驾驶员舒适度评价指标C,并表征综合评价指标S,确定综合评价指标S最大时的路权切换次数m,控制主道车辆和匝道车辆根据汇流。本发明减少了汇流时车道的路权切换次数,大大提升了汇流点车辆的通过效率,不仅降低了驾驶操作疲劳感,还降低了车辆的燃油消耗量,同时满足了舒适性和经济性的要求。
