DEMO: A Dynamics-Enhanced Learning Model for Multi-Horizon Trajectory Prediction in Autonomous Vehicles

  • 分两阶段建模:先学车辆动力学,再学交互关系。
  • 在四个数据集上短/长时程预测均优于现有方法。
  • 适合需要高安全性的自动驾驶轨迹预测场景。

自动驾驶汽车依赖对周边车辆轨迹的精准预测以保障乘客及其他道路使用者的安全。轨迹预测涵盖短期与长期两个时间尺度,各有不同需求:短期预测需准确捕捉车辆动力学特性,长期预测则需建模环境中的交互模式。然而,现有物理驱动或学习驱动的方法往往忽略这种差异,难以在两种时域下同时取得最优性能。本文提出动力学增强学习模型(DEMO),将车辆动力学模型与先进深度学习算法相结合。DEMO采用两阶段架构,第一阶段聚焦车辆运动动力学建模,第二阶段专注于交互关系学习。通过融合两类方法的优势,实现对未来轨迹的多时程预测。在Next Generation Simulation(NGSIM)、Macau Connected Autonomous Driving(MoCAD)、Highway Drone(HighD)和nuScenes数据集上的实验表明,DEMO在短期与长期预测任务中均优于当前最先进(SOTA)基线方法。

原文摘要 · Abstract (English)

Autonomous vehicles (AVs) rely on accurate trajectory prediction of surrounding vehicles to ensure the safety of both passengers and other road users. Trajectory prediction spans both short-term and long-term horizons, each requiring distinct considerations: short-term predictions rely on accurately capturing the vehicle's dynamics, while long-term predictions rely on accurately modeling the interaction patterns within the environment. However current approaches, either physics-based or learning-based models, always ignore these distinct considerations, making them struggle to find the optimal prediction for both short-term and long-term horizon. In this paper, we introduce the Dynamics-Enhanced Learning MOdel (DEMO), a novel approach that combines a physics-based Vehicle Dynamics Model with advanced deep learning algorithms. DEMO employs a two-stage architecture, featuring a Dynamics Learning Stage and an Interaction Learning Stage, where the former stage focuses on capturing vehicle motion dynamics and the latter focuses on modeling interaction. By capitalizing on the respective strengths of both methods, DEMO facilitates multi-horizon predictions for future trajectories. Experimental results on the Next Generation Simulation (NGSIM), Macau Connected Autonomous Driving (MoCAD), Highway Drone (HighD), and nuScenes datasets demonstrate that DEMO outperforms state-of-the-art (SOTA) baselines in both short-term and long-term prediction horizons.
