- 利用轨迹和感知动量,结合拓扑匹配与交叉注意力优化规划查询。
- 在nuScenes上实现超3秒的长期一致性,6秒内碰撞率降低26%。
- 适合关注自动驾驶规划鲁棒性与长期稳定性的研究者和工程师。
端到端自动驾驶框架虽能无缝集成感知与规划,但常依赖单帧一次性轨迹预测,易导致控制不稳定且对遮挡敏感。为此,本文提出动量感知驾驶(MomAD)框架,引入轨迹动量与感知动量以稳定并优化轨迹预测。该框架包含两个核心模块:(1) 拓扑轨迹匹配(TTM)使用豪斯多夫距离选择与历史路径一致的最优规划查询,确保连贯性;(2) 动量规划交互器(MPI)对选定查询与历史查询进行交叉注意力,扩展静态与动态感知信息。经增强的查询可重构长时程轨迹,降低碰撞风险。为缓解动态环境噪声与检测误差影响,训练中引入鲁棒实例去噪,使模型聚焦关键信号。此外,提出新的轨迹预测一致性(TPC)度量,量化评估规划稳定性。在nuScenes数据集上,MomAD相比当前最优方法实现≥3秒的长期一致性。在精选的Turning-nuScenes上,碰撞率下降26%,TPC提升0.97米(33.45%),6秒预测期内表现显著。闭环测试Bench2Drive显示成功率最高提升16.3%。
原文摘要 · Abstract (English)
End-to-end autonomous driving frameworks enable seamless integration of perception and planning but often rely on one-shot trajectory prediction, which may lead to unstable control and vulnerability to occlusions in single-frame perception. To address this, we propose the Momentum-Aware Driving (MomAD) framework, which introduces trajectory momentum and perception momentum to stabilize and refine trajectory predictions. MomAD comprises two core components: (1) Topological Trajectory Matching (TTM) employs Hausdorff Distance to select the optimal planning query that aligns with prior paths to ensure coherence;(2) Momentum Planning Interactor (MPI) cross-attends the selected planning query with historical queries to expand static and dynamic perception files. This enriched query, in turn, helps regenerate long-horizon trajectory and reduce collision risks. To mitigate noise arising from dynamic environments and detection errors, we introduce robust instance denoising during training, enabling the planning model to focus on critical signals and improve its robustness. We also propose a novel Trajectory Prediction Consistency (TPC) metric to quantitatively assess planning stability. Experiments on the nuScenes dataset demonstrate that MomAD achieves superior long-term consistency (>=3s) compared to SOTA methods. Moreover, evaluations on the curated Turning-nuScenes shows that MomAD reduces the collision rate by 26% and improves TPC by 0.97m (33.45%) over a 6s prediction horizon, while closedloop on Bench2Drive demonstrates an up to 16.3% improvement in success rate.
