摘要:

基于学习的智能能量管理系统对于插电式混合动力汽车(PHEV)实现高效能源利用至关重要。然而,其在现实世界中的应用面临系统可靠性挑战,阻碍了原始设备制造商(OEMs)的广泛接受。本文首先基于物理模型和数据驱动模型建立PHEV模型,重点构建高保真训练环境。随后,提出一种面向实车应用的控制框架,将基于时域扩展强化学习(RL)的能量管理与等效消耗最小化策略(ECMS)相结合,以提升实际适用性,并改进现有研究中基于瞬时驾驶循环和动力总成状态的等效因子评估方法所存在的缺陷。最后,开展了全面仿真和硬件在环验证,结果表明所提控制框架在燃油经济性方面优于自适应ECMS和基于规则的策略。与直接控制动力总成部件的传统RL架构相比,所提控制方法不仅实现了相近的最优性,还显著增强了能量管理系统的抗干扰能力,为OEMs面向实车应用的基于RL的能量管理策略提供了有效的控制框架。

英文摘要:

Learning-based intelligent energy management systems for plug-in hybrid electric vehicles (PHEVs) are crucial for achieving efficient energy utilization. However, their application faces system reliability challenges in the real world, which prevents widespread acceptance by original equipment manufacturers (OEMs). This paper begins by establishing a PHEV model based on physical and data-driven models, focusing on the high-fidelity training environment. It then proposes a real-vehicle application-oriented control framework, combining horizon-extended reinforcement learning (RL)-based energy management with the equivalent consumption minimization strategy (ECMS) to enhance practical applicability, and improves the flawed method of equivalent factor evaluation based on instantaneous driving cycle and powertrain states found in existing research. Finally, comprehensive simulation and hardware-in-the-loop validation are carried out which demonstrates the advantages of the proposed control framework in fuel economy over adaptive-ECMS and rule-based strategies. Compared to conventional RL architectures that directly control powertrain components, the proposed control method not only achieves similar optimality but also significantly enhances the disturbance resistance of the energy management system, providing an effective control framework for RL-based energy management strategies aimed at real-vehicle applications by OEMs.
