Neurosymbolic Planning Using Natural Language Communication for Cooperative Autonomous Vehicles
UNCAP is a new framework for cooperative autonomous driving that enables vehicles to communicate using natural language to share observations and reduce uncertainty. The approach uses vision-language models and uncertainty calibration to determine which messages to trust and how to integrate them into driving decisions. Evaluated in CARLA using the OPV2V benchmark, UNCAP shows significant improvements in communication efficiency, safety, and decision-making compared to traditional methods and prior language-based approaches.
