AutoMoT: A Unified Vision-Language-Action Model with Asynchronous Mixture-of-Transformers for End-to-End Autonomous Driving

AutoMoT is a unified Vision-Language-Action (VLA) framework for end-to-end autonomous driving. It features an Asynchronous Mixture-of-Transformers (MoT) architecture that unifies scene reasoning and action generation within a single model.

Method Overview

AutoMoT employs a fast-slow inference mechanism through its Asynchronous Mixture-of-Transformers design:

Understanding Expert (4B): Performs low-frequency, high-level reasoning to understand complex driving scenes.
Action Expert (1.6B): Operates at a higher frequency to decode 3-second driving decisions and spatial-temporal waypoints via KV-cache bridging.

This architecture preserves the general reasoning capabilities of pre-trained Vision-Language Models (VLMs) while ensuring the low-latency inference required for real-time autonomous vehicle control.

Benchmark Results

AutoMoT achieves SOTA performance on the Bench2Drive 220-route closed-loop evaluation (CARLA 0.9.15):

Driving Score (DS): 89.42
Success Rate (SR): 74.09
