摘要:

本文提出了一种在线轨迹规划方法,用于插电式混合动力汽车(HEV)中燃料电池(FC)与电池的最优协调。插电式HEV能量管理的主要挑战之一,是在驾驶场景高度不确定的情况下,通过最优地耗尽电池来生成荷电状态(SOC)参考曲线。近期研究已开始探索利用部分行程信息进行最优SOC轨迹规划的潜力,但未考虑FC系统的动态响应。另一方面,关注FC系统动态运行的研究往往集中于空气流量管理,电池仅被部分处理。我们的目标是通过设计一个在线轨迹规划器来填补这一空白,该规划器用于FC与电池系统的动态协调,并以分层方式与高层SOC规划器协同工作。我们提出了一种基于迭代LQR的在线轨迹规划方法,其中每个驾驶段可放电的电量可由高层规划器明确且自适应地指定。数值结果作为概念验证示例,展示了所提方法的有效性。

英文摘要:

This paper presents an online trajectory planning approach for optimal coordination of Fuel Cell (FC) and battery in plug-in Hybrid Electric Vehicle (HEV). One of the main challenges in energy management of plug-in HEV is generating State-of-Charge (SOC) reference curves by optimally depleting battery under high uncertainties in driving scenarios. Recent studies have begun to explore the potential of utilizing partial trip information for optimal SOC trajectory planning, but dynamic responses of the FC system are not taken into account. On the other hand, research focusing on dynamic operation of FC systems often focuses on air flow management, and battery has been treated only partially. Our aim is to fill this gap by designing an online trajectory planner for dynamic coordination of FC and battery systems that works with a high-level SOC planner in a hierarchical manner. We propose an iterative LQR based online trajectory planning method where the amount of electricity dischargeable at each driving segment can be explicitly and adaptively specified by the high-level planner. Numerical results are provided as a proof of concept example to show the effectiveness of the proposed approach.
