让感知随规划动态调整,提升自动驾驶决策精度
Perception in Plan: Coupled Perception and Planning for End-to-End Autonomous Driving
- 感知与规划耦合,按规划目标动态聚焦关键区域
- 使用多模态轨迹先验,感知结果直接服务路径生成
- 自回归逐步预测,适合实时端到端自动驾驶系统
端到端自动驾驶近年取得显著进展。现有方法通常采用感知-规划的串行范式,在可微框架下优化规划目标。本文提出感知即规划(Perception-in-Plan)新框架,将感知融入规划过程,使感知随规划目标动态演化,从而提升规划性能。基于此,我们设计VeteranAD框架:通过引入多模式锚定轨迹作为规划先验,感知模块针对性地采集这些轨迹上的交通元素,实现全面且精准的感知;规划轨迹则结合感知结果与先验生成。为使感知完全服务于规划,采用自回归策略,每步逐步预测未来轨迹并聚焦相关区域进行定向感知。该设计简单有效,充分释放了面向规划的端到端方法潜力,使驾驶行为更准确可靠。在NAVSIM和Bench2Drive数据集上的大量实验表明,VeteranAD达到当前最优性能。
原文摘要 · Abstract (English)
End-to-end autonomous driving has achieved remarkable advancements in recent years. Existing methods primarily follow a perception-planning paradigm, where perception and planning are executed sequentially within a fully differentiable framework for planning-oriented optimization. We further advance this paradigm through a perception-in-plan framework design, which integrates perception into the planning process. This design facilitates targeted perception guided by evolving planning objectives over time, ultimately enhancing planning performance. Building on this insight, we introduce VeteranAD, a coupled perception and planning framework for end-to-end autonomous driving. By incorporating multi-mode anchored trajectories as planning priors, the perception module is specifically designed to gather traffic elements along these trajectories, enabling comprehensive and targeted perception. Planning trajectories are then generated based on both the perception results and the planning priors. To make perception fully serve planning, we adopt an autoregressive strategy that progressively predicts future trajectories while focusing on relevant regions for targeted perception at each step. With this simple yet effective design, VeteranAD fully unleashes the potential of planning-oriented end-to-end methods, leading to more accurate and reliable driving behavior. Extensive experiments on the NAVSIM and Bench2Drive datasets demonstrate that our VeteranAD achieves state-of-the-art performance.
