Kinematics-Aware Latent World Models for Data-Efficient Autonomous Driving
TLDR
A kinematics-aware latent world model improves sample efficiency and driving performance in autonomous driving simulation.
Reasoning
The paper presents a novel integration of kinematic information into RSSM-based world models, with geometry-aware supervision, showing clear improvements in simulation benchmarks. However, it lacks real-world validation and does not compare against recent large-scale world models.

Innovations
- Incorporating vehicle kinematic information into the observation encoder to ground latent transitions in physically meaningful motion dynamics
- Geometry-aware supervision to regularize the RSSM latent state to capture task-relevant spatial structure beyond pixel reconstruction
Methodology
The framework builds upon the Recurrent State-Space Model (RSSM) and integrates vehicle kinematic information into the observation encoder to enforce physically meaningful latent dynamics. Geometry-aware supervision is applied to regularize the latent state, enabling the model to capture spatial structure beyond pixel reconstruction. The approach is evaluated in a driving simulation benchmark against model-free and pixel-based world-model baselines.
Key Results
The proposed method achieves consistent gains in sample efficiency and driving performance over both model-free and pixel-based world-model baselines. Ablation studies further verify that the design enhances spatial representation quality within the latent space.
