The invention relates to a vehicle team length control method and system for network automatic driving, and the method comprises the following steps: building a mixed flow system dynamic model through analyzing the dynamic operation characteristics of a novel mixed traffic flow; upstream road section traffic state information and converging area ramp traffic state information are obtained, different network connection automatic driving motorcade length strategies are set, and traffic capacities corresponding to different motorcade lengths are calculated in combination with a mixed flow system dynamic model; and selecting a motorcade length strategy corresponding to the maximum traffic capacity, and correspondingly controlling an upstream networked automatic driver to form a team according to the motorcade length strategy. Compared with the prior art, the traffic capacity model under the novel mixed traffic flow condition is established, the influence of the length and permeability change of the networked automatic driving motorcade on the road traffic capacity is revealed, a decision basis is provided for dynamic management of the motorcade, the advantages of networked automatic driving collaborative formation and accurate control can be fully utilized, and the reliability of the system is improved. And active and refined traffic control is realized.

    本发明涉及一种面向网联自动驾驶的车队长度控制方法及系统,该方法包括以下:通过解析新型混合交通流动态运行特性,建立混合流系统动态模型;获取上游路段交通状态信息和合流区匝道交通状态信息,并设置不同网联自动驾驶车队长度策略,结合混合流系统动态模型,计算得到不同车队长度对应的通行能力;选择最大通行能力对应的车队长度策略,据此相应控制上游网联自动驾驶按照该车队长度策略进行组队行驶。与现有技术相比,本发明通过建立新型混合交通流条件下的通行能力模型,揭示网联自动驾驶车队长度、渗透率变化对道路通行能力的影响,为车队动态管理提供决策依据,能够充分利用网联自动驾驶协同编队、精准控制优势,实现主动精细化的交通管控。
