AI总结:

针对多模态大语言模型语义理解难转化为自动驾驶控制指令、跨场景泛化性不足的问题,提出类人思维链框架Sce2DriveX,结合多模态学习与重构驾驶认知链,搭配专用VQA数据集,实现端到端驾驶的最优性能与强泛化性。

摘要:

端到端自动驾驶可直接将原始传感器输入映射为车辆底层控制指令,是具身智能(Embodied AI)的重要组成部分。尽管多模态大语言模型(Multimodal Large Language Models, MLLMs)在高层交通场景语义理解方面已取得成功,但如何将这些概念性语义理解有效转化为底层运动控制指令,并实现跨场景驾驶的泛化性与一致性,仍是一大挑战。我们提出了Sce2DriveX,这是一种类人驾驶思维链(chain-of-thought, CoT)推理的MLLM框架。Sce2DriveX利用局部场景视频与全局鸟瞰图(BEV)的多模态联合学习,深度理解长程时空关系与道路拓扑结构,增强其在3D动静态场景中的综合感知与推理能力,实现跨场景的驾驶泛化。在此基础上,该框架重构了人类驾驶中固有的内隐认知链,涵盖场景理解、元动作推理、行为解释分析、运动规划与控制,从而进一步缩小自动驾驶与人类思维过程之间的差距。为提升模型性能,我们构建了首个面向3D空间理解与长轴任务推理的大规模视觉问答(Visual Question Answering, VQA)驾驶指令数据集。大量实验表明,Sce2DriveX在从场景理解到端到端驾驶的任务上均达到了当前最优(state-of-the-art)性能,并且在CARLA Bench2Drive基准测试上展现出强大的泛化能力。

英文摘要:

End-to-end autonomous driving, which directly maps raw sensor inputs to low-level vehicle controls, is an important part of Embodied AI. Despite successes in applying Multimodal Large Language Models (MLLMs) for high-level traffic scene semantic understanding, it remains challenging to effectively translate these conceptual semantics understandings into low-level motion control commands and achieve generalization and consensus in cross-scene driving. We introduce Sce2DriveX, a human-like driving chain-of-thought (CoT) reasoning MLLM framework. Sce2DriveX utilizes multimodal joint learning from local scene videos and global BEV maps to deeply understand long-range spatiotemporal relationships and road topology, enhancing its comprehensive perception and reasoning capabilities in 3D dynamic/static scenes and achieving driving generalization across scenes. Building on this, it reconstructs the implicit cognitive chain inherent in human driving, covering scene understanding, meta-action reasoning, behavior interpretation analysis, motion planning and control, thereby further bridging the gap between autonomous driving and human thought processes. To elevate model performance, we have developed the first extensive Visual Question Answering (VQA) driving instruction dataset tailored for 3D spatial understanding and long-axis task reasoning. Extensive experiments demonstrate that Sce2DriveX achieves state-of-the-art performance from scene understanding to end-to-end driving, as well as robust generalization on the CARLA Bench2Drive benchmark.
