Autonomous Driving End-to-End Planning Mixture of Experts Autoregressive Modeling Trajectory Planning NAVSIM

Problem

Traditional modular systems suffer from cumulative error propagation, while existing end-to-end models rely on static one-shot inference that fails to capture dynamic environmental changes and diverse driving behaviors.

Approach

The framework sequentially generates trajectory waypoints while dynamically routing scene-specific queries to specialized expert networks, enhanced by a lightweight batch reallocation strategy for efficient training.

Key results

  • First integration of Mixture-of-Experts into end-to-end autonomous driving planning
  • Autoregressive waypoint generation preserves temporal dependencies and handles ambiguous guidance
  • Achieves 86.9 PDMS and 83.1 EPDMS on the NAVSIM dataset with a ResNet-34 backbone
  • Lightweight batch reallocation strategy significantly accelerates expert network training

Why it matters

Provides a robust, adaptive planning framework that overcomes static model limitations, advancing reliable autonomous navigation for diverse real-world scenarios.

Abstract

This paper presents ARTEMIS, an end-to-end au- tonomous driving framework that combines autoregressive tra- jectory planning with Mixture-of-Experts (MoE). Traditional modular methods suffer from error propagation, while existing end-to-end models typically employ static one-shot inference paradigms that inadequately capture the dynamic changes of the environment. ARTEMIS takes a different method by generating trajectory waypoints sequentially, preserves critical temporal dependencies while dynamically routing scene-specific queries to specialized expert networks. It effectively relieves trajectory quality degradation issues encountered when guidance informa- tion is ambiguous, and overcomes the inherent representational limitations of singular network architectures when processing diverse driving scenarios. Additionally, we use a lightweight batch reallocation strategy that significantly improves the training speed of the Mixture-of-Experts model. Through experiments on the NAVSIM dataset, ARTEMIS exhibits superior competitive performance, achieving 86.9 PDMS and 83.1 EPDMS with ResNet-34 backbone, demonstrates state-of-the-art performance on multiple metrics. Code will be available under https://github. com/Lg0914/ARTEMIS.
