Research Paper
Core Innovation
This paper introduces AdaThinkDrive, which adaptively switches between fast and slow reasoning modes to optimize computational resources and decision quality in autonomous driving. It uniquely combines a two-mode dataset and an Adaptive Think Reward with Group Relative Policy Optimization to train the model to selectively apply Chain of Thought reasoning only when beneficial. This approach surpasses fixed reasoning baselines in both performance and efficiency.

Research Paper Overview
AdaThinkDrive: Adaptive Thinking via Reinforcement Learning for Autonomous Driving
Summary
AdaThinkDrive is a vision language action framework for autonomous driving that adaptively applies Chain of Thought reasoning only when needed, improving decision quality and efficiency. It uses a dual mode reasoning mechanism inspired by fast and slow thinking, pretrained on large-scale driving data, and fine-tuned with a two-mode dataset to distinguish scenarios requiring reasoning. An Adaptive Think Reward combined with Group Relative Policy Optimization encourages selective reasoning, achieving higher performance and reduced inference time on the Navsim benchmark.
