Sim2Real-AD: A Modular Sim-to-Real Framework for Deploying VLM-Guided Reinforcement Learning in Real-World Autonomous Driving
arXiv:2604.03497v2 Announce Type: replace-cross Abstract: Vision-language-model (VLM)-guided reinforcement learning (RL) has recently attracted significant attention for it, replacing brittle hand-crafted rewards with semantically grounded signals; however, deploying such simulation-trained policies on real vehicles remains a fundamental challenge, because they rely on simulator-native observations and simulator-coupled action semantics with no counterpart on physical hardware. We identify a general principle: the simulation-to-reality gap decomposes into two largely orthogonal axes, a sensing
The increasing sophistication of vision-language models makes their integration into reinforcement learning for real-world autonomous systems a natural next step, despite the persistent sim-to-real gap.
This development moves beyond fragile hand-crafted reward systems in autonomous driving, enabling more generalizable and semantically grounded policy learning, accelerating deployment to physical hardware.
Autonomous driving policy training can now leverage VLM guidance, drastically reducing the gap between simulated learning environments and real-world deployment challenges by modularizing sensing and action problems.

More robust and adaptable autonomous driving systems emerge with reduced development cycles due to improved sim-to-real transfer.
Generalized VLM-guided RL frameworks could extend to other complex robotic control tasks beyond autonomous driving, leading to broader automation of hazardous or precise operations.
The enhanced capability for autonomous systems to interpret and act on semantic cues could redefine human-machine interaction and expand the scope of AI agentic systems in physical environments.
