摘要:

提出了一种新的综合方法,以处理的决策和运动规划的自动驾驶汽车(AV)的车道变换操纵考虑周围交通乘员的社会行为。通过驾驶风格和周围车辆的意图来反映,在建模过程中考虑了社会行为。然后,应用Stackelberg博弈理论解决决策问题,将其转化为一个非合作博弈问题。此外,在运动规划模型中引入势场,利用不同的势函数来描述周围车辆的不同行为和道路约束。然后,利用模型预测控制(MPC)来预测自主车辆的状态和轨迹。最后,决策和运动规划,然后集成到一个有约束的多目标优化问题。考虑到周围车辆的不同社会行为的三个测试场景进行了验证所提出的方法的性能。测试结果表明,该集成方法能够解决与其他交通参与者的不同社会互动,为自动驾驶汽车做出正确、安全的决策和规划,证明了其可行性和有效性。

英文摘要:

This paper presents a novel integrated approach to deal with the decision making and motion planning for lane-change maneuvers of autonomous vehicle (AV) considering social behaviors of surrounding traffic occupants. Reflected by driving styles and intentions of surrounding vehicles, the social behaviors are taken into consideration during the modelling process. Then, the Stackelberg Game theory is applied to solve the decision-making, which is formulated as a non-cooperative game problem. Besides, potential field is adopted in the motion planning model, which uses different potential functions to describe surrounding vehicles with different behaviors and road constrains. Then, Model Predictive Control (MPC) is utilized to predict the state and trajectory of the autonomous vehicle. Finally, the decision-making and motion planning is then integrated into a constrained multi-objective optimization problem. Three testing scenarios considering different social behaviors of surrounding vehicles are carried out to validate the performance of the proposed approach. Testing results show that the integrated approach is able to address different social interactions with other traffic participants, and make proper and safe decisions and planning for autonomous vehicles, demonstrating its feasibility and effectiveness.
