摘要:

视觉语言模型最近成为自主驾驶领域有前景的规划器,其成功依赖于对多模态输入中空间结构和动态交互的拓扑感知推理。然而,现有模型通常在训练时没有明确编码这些关系依赖的监督信号,限制了它们从原始传感器数据推断智能体和其他交通实体如何相互影响的能力。在这项工作中,我们通过一种新颖的模型无关方法弥合了这一差距,该方法以交通场景图的形式将语言驾驶模型条件化于结构化关系上下文。我们在不同的抽象层次和格式下序列化场景图,并通过结构化提示模板将其融入模型,从而能够系统分析关系监督在何时以及如何最有益且计算高效。在LangAuto和Bench2Drive基准上的广泛评估表明,场景图条件化带来了巨大且持续的改进。我们观察到,与竞争的LMDrive、BEVDriver和SimLingo基线相比,我们提出的方法的驾驶分数有显著提升。这些结果表明,即使测试时不需要场景图输入,多样化的架构也能通过场景图条件化训练有效内化和基于关系先验。代码、微调模型和我们的场景图数据集已在此https URL公开。

英文摘要:

Vision-language models have recently emerged as promising planners for autonomous driving, where success hinges on topology-aware reasoning over spatial structure and dynamic interactions from multimodal input. However, existing models are typically trained without supervision that explicitly encodes these relational dependencies, limiting their ability to infer how agents and other traffic entities influence one another from raw sensor data. In this work, we bridge this gap with a novel model-agnostic method that conditions language-based driving models on structured relational context in the form of traffic scene graphs. We serialize scene graphs at various abstraction levels and formats, and incorporate them into models via structured prompt templates, enabling systematic analysis of when and how relational supervision is most beneficial and computationally efficient. Extensive evaluations on the LangAuto and Bench2Drive benchmarks show that scene graph conditioning yields large and persistent improvements. We observe a substantial performance increase in the Driving Score of our proposed approach versus competitive LMDrive, BEVDriver, and SimLingo baselines. These results indicate that diverse architectures can effectively internalize and ground relational priors through scene graph-conditioned training, even without requiring scene graph input at test-time. Code, fine-tuned models, and our scene graph dataset are publicly available at https://github.com/iis-esslingen/GraphPilot.
