摘要:

本文提出了一种分布式算法,用于解决高度受限空间中的多车辆协同冲突问题。通过将冲突解决问题制定为多智能体强化学习(RL)问题,我们可以离线训练策略,以在简化的离散环境中安全有效地驾驶车辆驶向目的地。在在线执行过程中,每个车辆首先用训练好的策略模拟车辆之间的交互,以获得其策略,该策略用于指导参考轨迹的计算。然后,提出了一种分布式模型预测控制器(MPC)跟踪的参考,同时避免冲突。初步结果表明,RL和分布式MPC的组合有可能引导车辆安全顺利地解决冲突,同时比集中式方法的计算要求更低。

英文摘要:

This work presents a distributed algorithm for resolving cooperative multi-vehicle conflicts in highly constrained spaces. By formulating the conflict resolution problem as a Multi-Agent Reinforcement Learning (RL) problem, we can train a policy offline to drive the vehicles towards their destinations safely and efficiently in a simplified discrete environment. During the online execution, each vehicle first simulates the interaction among vehicles with the trained policy to obtain its strategy, which is used to guide the computation of a reference trajectory. A distributed Model Predictive Controller (MPC) is then proposed to track the reference while avoiding collisions. The preliminary results show that the combination of RL and distributed MPC has the potential to guide vehicles to resolve conflicts safely and smoothly while being less computationally demanding than the centralized approach.
