Mehmet Fatih Ozkan, Yao Ma

摘要:

人类主导的卡车排队系统已经被提出来利用人类监督和车辆自主性两者的益处。配备了人工引导和自主技术,人类主导的卡车排队系统比全自动排队系统更能应对不确定的交通状况。提出了一种新的分布式随机模型预测控制(DSMPC)设计的人主导重型卡车车队。建议DSMPC设计集成了随机驾驶员行为模型的人驱动的领导卡车的分布式编队控制设计的以下自动化卡车的排。人类驾驶的领导卡车的驾驶员行为的学习随机逆强化学习(SIRL)的方法。所提出的随机驾驶员行为模型的目的是学习代价函数的分布,其表示人类驾驶员行为的丰富性和独特性,具有给定的一组特定于驾驶员的示范。分布式编队控制包括一个串行DSMPC保证递归的可行性,闭环机会约束满足,和字符串稳定性。仿真研究进行调查的有效性,建议的设计在几个现实的交通情况下。与基线队列控制策略(确定性分布式模型预测控制)相比,所提出的DSMPC在约束违反和间距误差方面实现了优越的控制器性能。

英文摘要:

Human-leading truck platooning systems have been proposed to leverage the benefits of both human supervision and vehicle autonomy. Equipped with human guidance and autonomous technology, human-leading truck platooning systems are more versatile to handle uncertain traffic conditions than fully automated platooning systems. This paper presents a novel distributed stochastic model predictive control (DSMPC) design for a human-leading heavy-duty truck platoon. The proposed DSMPC design integrates the stochastic driver behavior model of the human-driven leader truck with a distributed formation control design for the following automated trucks in the platoon. The driver behavior of the human-driven leader truck is learned by a stochastic inverse reinforcement learning (SIRL) approach. The proposed stochastic driver behavior model aims to learn a distribution of cost function, which represents the richness and uniqueness of human driver behaviors, with a given set of driver-specific demonstrations. The distributed formation control includes a serial DSMPC with guaranteed recursive feasibility, closed-loop chance constraint satisfaction, and string stability. Simulation studies are conducted to investigate the efficacy of the proposed design under several realistic traffic scenarios. Compared to the baseline platoon control strategy (deterministic distributed model predictive control), the proposed DSMPC achieves superior controller performance in constraint violations and spacing errors.
