电动汽车(EV)在现代交通系统中的快速普及,使其能源感知路径规划成为成功集成的关键任务,尤其在电池剩余电量有限且充电设施难以获取的情况下,仅通过能耗最优路径才能抵达某些目的地:即比所有其他路线更省电的路径。此类路径的可行性高度依赖于能量模型的准确性,忽略车辆动力学会导致能耗估算失真,使规划路径在现实中不可行。本文研究车辆动力学对电动车能耗最优路径规划的影响。首先,分析能量模型精度如何影响路径搜索及行程可行性,采用一种新颖的数据驱动模型,将关键车辆动力学参数纳入能耗计算。此外,提出两种新型在线重加权和能量启发函数,解决再生制动带来的负能耗问题,使方法更适用于实时应用。在真实世界交通网络上的大量实验表明,该方法显著提升了电动车能耗最优路径规划的计算效率。

原文摘要 · Abstract (English)

The rapid adoption of electric vehicles (EVs) in modern transport systems has made energy-aware routing a critical task in their successful integration, especially within large-scale transport networks. In cases where an EV's remaining energy is limited and charging locations are not easily accessible, some destinations may only be reachable through an energy-optimal path: a route that consumes less energy than all other alternatives. The feasibility of such energy-efficient paths depends heavily on the accuracy of the energy model used for planning, and thus failing to account for vehicle dynamics can lead to inaccurate energy estimates, rendering some planned routes infeasible in reality. This paper explores the impact of vehicle dynamics on energy-optimal path planning for EVs. We first investigate how energy model accuracy influences energy-optimal pathfinding and, consequently, feasibility of planned trips, using a novel data-driven model that incorporates key vehicle dynamics parameters into energy calculations. Additionally, we introduce two novel online reweighting and energy heuristic functions that accelerate path planning with negative energy costs arise due to regenerative braking, making our approach well-suited for real-time applications. Extensive experiments on real-world transport networks demonstrate that our method significantly improves both the computational efficiency of energy-optimal pathfinding for EVs.
