摘要:

为解决多车道合流区车辆的安全性和效率问题,采用联盟博弈方法设计了一种互联自动车辆(CAV)协同决策框架.首先,在简化的单轨车辆模型基础上建立了运动预测模块,提高了决策算法的准确性和可靠性。在此基础上,综合考虑安全性、舒适性和效率等多个性能指标,设计了代价函数和决策约束条件。此外,为了实现人性化和个性化的智能移动性,不同的驾驶特性被考虑和嵌入到建模过程中。在此基础上,提出了多车道合流区情况下CAVS的四种典型联盟模型。然后,联盟博弈的方法制定了模型预测控制(MPC),以处理在定义的场景CAV的决策。最后,在考虑不同驾驶特性的两种情况下进行测试,以评估所开发的方法的性能。试验结果表明,该方法能够对多车道合流区的CAV进行合理的决策,并能适应不同的行驶特性。该方法既保证了CAV在复杂动态交通条件下的安全性和有效性,又兼顾了单个车辆的目标,验证了该方法的可行性和有效性。

英文摘要:

To address the safety and efficiency issues of vehicles at multi-lane merging zones, a cooperative decision-making framework is designed for connected automated vehicles (CAVs) using a coalitional game approach. Firstly, a motion prediction module is established based on the simplified single-track vehicle model for enhancing the accuracy and reliability of the decision-making algorithm. Then, the cost function and constraints of the decision making are designed considering multiple performance indexes, i.e. the safety, comfort and efficiency. Besides, in order to realize human-like and personalized smart mobility, different driving characteristics are considered and embedded in the modeling process. Furthermore, four typical coalition models are defined for CAVS at the scenario of a multi-lane merging zone. Then, the coalitional game approach is formulated with model predictive control (MPC) to deal with decision making of CAVs at the defined scenario. Finally, testings are carried out in two cases considering different driving characteristics to evaluate the performance of the developed approach. The testing results show that the proposed coalitional game based method is able to make reasonable decisions and adapt to different driving characteristics for CAVs at the multi-lane merging zone. It guarantees the safety and efficiency of CAVs at the complex dynamic traffic condition, and simultaneously accommodates the objectives of individual vehicles, demonstrating the feasibility and effectiveness of the proposed approach.
