The invention is suitable for the technical field of traffic control and intelligent vehicle control, and provides a signalized intersection energy-saving control method considering an effect threshold value, which comprises the following steps of: constructing a bidirectional six-lane signalized intersection scene, dividing functional areas of the intersection, controlling a vehicle to complete lane change in a lane change area by a controller, and then controlling the speed of the vehicle. Then, for the situation that the control effect of the high traffic flow is deteriorated, a threshold value considering the traffic flow is obtained through simulation analysis, two control methods are designed in a controller, the first control method is applied to vehicle-road cooperative control under the medium-low traffic flow, and the second control method is applied to vehicle-road cooperative control under the medium-low traffic flow based on logic judgment and calculation; current vehicle parameters and traffic information are divided into four types of control models, so that reduction of parking times and passing time is taken as guidance, and economy is considered; and the second type is applied to intersection speed control under high flow, takes the vehicle energy consumption economy as guidance, considers the vehicle speed obtained by the first type control method, sets an adjustable weight factor, and improves the passing efficiency as much as possible.
本发明适用于交通控制与智能车控制技术领域,提供了一种考虑效果阈值的信号交叉口节能控制方法,先构建一个双向六车道的信号交叉口场景,对交叉口进行功能区的划分,控制器控制车辆在换道区先完成换道,再进行速度控制。然后针对高车流量出现控制效果恶化的情况,经过仿真分析得到一个考虑交通流量的阈值,并在控制器中设计两类控制方法,第一类应用于中低车流量下的车路协同控制,基于逻辑判断与计算,以当前车辆参数和交通信息划分四类控制模型,以减少停车次数和通行时间为导向,兼顾经济性;第二类应用于高流量下的交叉口速度控制,以车辆能耗经济性为导向,并考虑由第一类控制方法得到的车速,设置可调权重因子,尽可能提升通行效率。
