AI总结:

本文提出了一种结合Mamba和注意力机制的扩散模型,通过整合物理约束提升自动驾驶轨迹预测的准确性和可解释性。

摘要:

自动驾驶系统需要轨迹规划器,不仅要建模未来运动的内在不确定性,还要尊重复杂的时序依赖性和底层物理定律。尽管基于扩散的生成模型在捕捉多模分布方面表现出色,但它们往往无法融入长期的序列上下文和领域特定的物理先验。在本工作中,我们通过两个关键创新来弥合这些差距。首先,我们引入了一种扩散Mamba变换器架构,将Mamba和注意力嵌入到扩散过程中,从而更有效地聚合来自传感器流和过去运动历史的序列输入上下文。其次,我们设计了一种端哈密顿神经网络模块,将基于能量的物理约束无缝整合到扩散模型中,从而通过一致性和可解释性增强轨迹预测。在标准自动驾驶基准上的广泛评估表明,我们的统一框架在预测准确性、物理合理性及鲁棒性方面显著优于最先进的基线,从而推进了安全可靠的运动规划。

英文摘要:

Autonomous driving systems demand trajectory planners that not only model the inherent uncertainty of future motions but also respect complex temporal dependencies and underlying physical laws. While diffusion-based generative models excel at capturing multi-modal distributions, they often fail to incorporate long-term sequential contexts and domain-specific physical priors. In this work, we bridge these gaps with two key innovations. First, we introduce a Diffusion Mamba Transformer architecture that embeds mamba and attention into the diffusion process, enabling more effective aggregation of sequential input contexts from sensor streams and past motion histories. Second, we design a Port-Hamiltonian Neural Network module that seamlessly integrates energy-based physical constraints into the diffusion model, thereby enhancing trajectory predictions with both consistency and interpretability. Extensive evaluations on standard autonomous driving benchmarks demonstrate that our unified framework significantly outperforms state-of-the-art baselines in predictive accuracy, physical plausibility, and robustness, thereby advancing safe and reliable motion planning.
