VLM-CASE: Vision-Language Model Enabled Context-Adaptive Safety Envelopes for Anticipatory Safe Autonomous Driving

Tianjia Yang, Ke Li, Ruwen Qin, Xianbiao Hu

Adverse driving conditions, such as bad weather, remain a principal barrier to autonomous driving because they degrade two things at once: what the vehicle can perceive and what it can physically do. Human drivers cope by anticipation, reasoning about the scene and re-budgeting s…

CCFM: Collision-Constrained Flow Matching for Safety-Critical Scenario Generation

Ke Li, Kaidi Liang, Yuxin Ding, Debojyoti Biswas, Xianbiao Hu, Ruwen Qin

Evaluation of autonomous vehicle (AV) planners in safety-critical closed-loop simulation is essential for real-world deployment. However, generating controllable safety-critical scenarios remains challenging. Existing approaches use soft guidance that provides only probabilistic…
