Researchers have developed a new approach to improve the visual grounding of Driving Vision-Language Models (VLAs) by framing trajectory prediction as an inverse kinematics problem. This method requires the model to predict both the current and future visual states, addressing a limitation in existing models that primarily rely on ego status and text commands. By incorporating a next visual state prediction objective and a dedicated Inverse Kinematics Network, a 0.5B-scale model achieved trajectory planning performance comparable to much larger VLAs, particularly in dynamic driving scenarios.
