近年来车道变道预测研究发展迅速,但多数工作局限于仿真或数据集结果,算法进展与实车部署之间存在差距。本文通过真实硬件验证,构建了一套基于知识图谱嵌入(KGEs)与贝叶斯推断的车道变道预测系统。该系统包含两个模块:(i) 感知模块,负责环境感知、提取数值特征并转换为语言类别,传送给预测模块;(ii) 预训练预测模块,执行KGE与贝叶斯推理模型,预测目标车辆操作,并转化为纵向制动动作以确保自身及周围车辆安全。实车硬件验证表明,本系统能提前3至4秒预测目标车辆的车道变道行为,为本车提供充足反应时间,使目标车辆可安全完成变道。
原文摘要 · Abstract (English)
Research on lane change prediction has gained a lot of momentum in the last couple of years. However, most research is confined to simulation or results obtained from datasets, leaving a gap between algorithmic advances and on-road deployment. This work closes that gap by demonstrating, on real hardware, a lane-change prediction system based on Knowledge Graph Embeddings (KGEs) and Bayesian inference. Moreover, the ego-vehicle employs a longitudinal braking action to ensure the safety of both itself and the surrounding vehicles. Our architecture consists of two modules: (i) a perception module that senses the environment, derives input numerical features, and converts them into linguistic categories; and communicates them to the prediction module; (ii) a pretrained prediction module that executes a KGE and Bayesian inference model to anticipate the target vehicle's maneuver and transforms the prediction into longitudinal braking action. Real-world hardware experimental validation demonstrates that our prediction system anticipates the target vehicle's lane change three to four seconds in advance, providing the ego vehicle sufficient time to react and allowing the target vehicle to make the lane change safely.
