本研究提出FPD-Drive端到端自动驾驶规划器,通过未来特权多目标蒸馏和安全感知分数校正提升多轨迹监督与安全选择,在NAVSIM、HUGSIM基准上实现SOTA性能。

摘要:

端到端自动驾驶模型通常在真实驾驶日志上训练,这些日志仅记录每个场景中实际执行的轨迹,这为学习其他有效行为提供的监督有限。多目标监督可缓解这一限制,但更广泛的轨迹覆盖会使安全候选选择更具挑战性。我们提出FPD-Drive,一种端到端规划器,它将特权未来知识蒸馏到视觉驾驶策略中,以改进多轨迹监督和安全选择。具体而言,我们引入未来特权多目标蒸馏,将来自可访问记录未来观测的教师模型的多样高质量轨迹目标迁移到学生模型,这些目标将监督扩展到单一记录的人类轨迹之外。对于候选选择,我们进一步引入安全感知分数校正,以修正附近安全与不安全候选之间的排名错误,并提高安全候选被低估的安全分数。部署时,学生模型既不需要未来观测也不需要教师推理。我们的基础模型在NAVSIM v1 navtest上达到94.9 PDMS,在NAVSIM v2 navhard上达到55.9 EPDMS;缩放后的FPD-Drive-Pro将这些分数分别提升至95.5 PDMS和58.1 EPDMS,在两个基准上均达到对比方法中的SOTA性能。在HUGSIM上的零样本闭环评估进一步产生45.1的HD-Score和55.3的RC。

英文摘要:

End-to-end autonomous driving models are typically trained on real-world driving logs, which record only the trajectory actually executed in each scene. This provides limited supervision for learning alternative valid behaviors. Multi-target supervision can mitigate this limitation, but broader trajectory coverage makes safe candidate selection more challenging. We propose FPD-Drive, an end-to-end planner that distills privileged future knowledge into a visual driving policy to improve both multi-trajectory supervision and safety selection. Specifically, we introduce Future-Privileged Multi-Target Distillation to transfer diverse, high-quality trajectory targets from a teacher with access to recorded future observations to the student. These targets extend supervision beyond the single recorded human trajectory. For candidate selection, we further introduce Safety-Aware Score Correction to correct ranking errors between nearby safe and unsafe candidates and raise underestimated safety scores of safe candidates. At deployment, the student requires neither future observations nor teacher inference. Our base model achieves 94.9 PDMS on NAVSIM v1 navtest and 55.9 EPDMS on NAVSIM v2 navhard. The scaled FPD-Drive-Pro improves these scores to 95.5 PDMS and 58.1 EPDMS, respectively, achieving SOTA performance among the compared methods on both benchmarks. Zero-shot closed-loop evaluation on HUGSIM further yields an HD-Score of 45.1 and RC of 55.3.
