摘要:

视觉-语言-动作(VLA)模型近期在端到端自动驾驶中取得了显著进展,通过在统一的多模态框架中整合感知、推理和控制。然而,它们通常缺乏对时间动态和全局世界一致性的显式建模,限制了前瞻性与安全性。相比之下,世界模型可以模拟合理的未来场景,但通常难以推理或评估生成的未来场景。在本文中,我们提出了VLA-World,一种简单而有效的VLA世界模型,将预测想象与反思推理统一起来以提高驾驶前瞻性。VLA-World首先使用动作导出的可行轨迹引导下一帧图像的生成,捕捉丰富的空间和时间线索,描述周围环境如何演变。模型随后对自动生成的未来想象帧进行推理,优化预测轨迹,实现更高的性能和更好的可解释性。为了支持此流程,我们整理了nuScenes-GR-20K,一个从nuScenes衍生的生成推理数据集,并采用了预训练、监督微调和强化学习三阶段训练策略。广泛的实验表明,VLA-World在规划和未来场景生成基准上一致优于现有最先进VLA和世界模型基线。项目页面:https://vlaworld.github.io

英文摘要:

Vision-Language-Action (VLA) models have recently achieved notable progress in end-to-end autonomous driving by integrating perception, reasoning, and control within a unified multimodal framework. However, they often lack explicit modeling of temporal dynamics and global world consistency, which limits their foresight and safety. In contrast, world models can simulate plausible future scenes but generally struggle to reason about or evaluate the imagined future they generate. In this work, we present VLA-World, a simple yet effective VLA world model that unifies predictive imagination with reflective reasoning to improve driving foresight. VLA-World first uses an action-derived feasible trajectory to guide the generation of the next-frame image, capturing rich spatial and temporal cues that describe how the surrounding environment evolves. The model then reasons over this self-generated future imagined frame to refine the predicted trajectory, achieving higher performance and better interpretability. To support this pipeline, we curate nuScenes-GR-20K, a generative reasoning dataset derived from nuScenes, and employ a three-stage training strategy that includes pretraining, supervised fine-tuning, and reinforcement learning. Extensive experiments demonstrate that VLA-World consistently surpasses state-of-the-art VLA and world-model baselines on both planning and future-generation benchmarks.
