The invention discloses a mixed traffic flow-oriented networked autonomous vehicle communication and cooperative control method, which is applied to the field of intelligent Internet of Vehicles and aims at solving the problem that in the prior art, limitation of communication resources and information updating requirements of digital twinning are difficult to balance and effective cooperation between CAVs is realized. According to the invention, the distributed digital twin system is constructed in each CAV, the road condition, the communication channel state and the driving strategy of the surrounding vehicles are monitored in real time and dynamically simulated, and the decision deficiency caused by the sensing limitation of a single vehicle is made up, so that the group intelligent collaboration among the vehicles is realized. While the individual driving style is reserved, the CAV can more effectively relieve the disturbance of HDV driving to traffic, and the efficiency and stability of traffic flow are remarkably improved. Besides, the pressure of perception information sharing on a communication system is fully considered in the CAV collaborative driving process, information with the highest decision-making value is optimized under the condition of limited communication resources, and the interaction frequency between vehicles is dynamically adjusted according to the channel state, so that the lightweight design is realized, and the cost is reduced. And the applicability and the reliability of the scheme in an actual application scene are further enhanced.
本发明公开一种面向混合交通流的网联自动驾驶汽车通信与协同控制方法,应用于智能车联网领域,针对现有技术难以平衡通信资源的限制与数字孪生的信息更新需求,实现CAV间的有效协同的问题;本发明通过在各CAV内部构建分布式数字孪生系统,对道路状况、通信信道状态及周围车辆的驾驶策略进行实时监控和动态模拟,弥补了单车感知局限带来的决策不足,从而实现车辆间的群体智能协同。在保留个体驾驶风格的同时,CAV能更有效地缓解HDV驾驶对交通的扰动,显著提升交通流的效率与稳定性。此外,本发明在CAV协同驾驶过程中充分考虑了感知信息共享对通信系统的压力,通过在有限通信资源条件下优选最具决策价值的信息,并根据信道状态动态调整车辆间的交互频率,实现了轻量化设计,进一步增强了方案在实际应用场景中的适用性和可靠性。
