Researchers have introduced Latent Chain-of-Thought-Drive (LCDrive), a novel approach for end-to-end autonomous driving that utilizes a latent language for reasoning instead of natural language. This model interleaves action-proposal tokens with world-model tokens grounded in a learned latent space to predict future outcomes of driving actions. Initial training is supervised by ground-truth future rollouts, followed by closed-loop reinforcement learning. LCDrive demonstrates faster inference, improved trajectory quality, and greater benefits from reinforcement learning compared to non-reasoning and text-based reasoning baselines on a large-scale driving benchmark.
