内燃机汽车与电动汽车具有不同的车辆动力学特性。电动汽车因电机可在更宽速度范围内输出峰值功率,具备快速加速能力,并可通过再生制动实现迅速减速。现有微观交通模型虽能较好刻画内燃机汽车的驾驶行为,但尚缺乏准确描述电动汽车独特跟车特性的建模框架。随着电动汽车在交通中的占比不断提升,构建此类模型至关重要,但同时兼具易用性与高精度仍具挑战。为此,本研究基于真实世界中配备自适应巡航控制(ACC)车辆的轨迹数据,开发并验证了一种面向电动汽车的相位感知人工智能(PAAI)跟车模型。该模型在传统物理基础框架上引入AI组件,可识别并适应快速加速、再生制动等不同驾驶阶段。通过全面仿真验证,结果表明:相比传统模型,PAAI模型在预测精度上显著提升,为准确模拟电动汽车交通行为提供了有效工具。
原文摘要 · Abstract (English)
Internal combustion engine (ICE) vehicles and electric vehicles (EVs) exhibit distinct vehicle dynamics. EVs provide rapid acceleration, with electric motors producing peak power across a wider speed range, and achieve swift deceleration through regenerative braking. While existing microscopic models effectively capture the driving behavior of ICE vehicles, a modeling framework that accurately describes the unique car-following dynamics of EVs is lacking. Developing such a model is essential given the increasing presence of EVs in traffic, yet creating an easy-to-use and accurate analytical model remains challenging. To address these gaps, this study develops and validates a Phase-Aware AI (PAAI) car-following model specifically for EVs. The proposed model enhances traditional physics-based frameworks with an AI component that recognizes and adapts to different driving phases, such as rapid acceleration and regenerative braking. Using real-world trajectory data from vehicles equipped with adaptive cruise control (ACC), we conduct comprehensive simulations to validate the model's performance. The numerical results demonstrate that the PAAI model significantly improves prediction accuracy over traditional car-following models, providing an effective tool for accurately representing EV behavior in traffic simulations.
