摘要:

本研究引入了一种新颖的自主运动规划方法,在Frenet坐标系中利用强化学习(RL)智能体为解析算法提供信息。这种结合直接解决了自动驾驶中的适应性和安全性挑战。运动规划算法对于在动态复杂场景中导航至关重要。然而,传统方法缺乏不可预测环境所需的灵活性,而机器学习技术,尤其是强化学习(RL),虽具备适应性,却存在不稳定性和缺乏可解释性的问题。我们独特的解决方案将传统运动规划算法的可预测性和稳定性与RL的动态适应性相协同,形成了一个能有效处理复杂情况并适应不断变化的环境条件的系统。对我们集成方法的评估表明,在多种场景下,碰撞显著减少,风险管理得到改善,目标成功率得到提高。本研究中使用的代码作为开源软件公开,可通过以下链接访问:https://github.com/TUM-AVS/Frenetix-RL。

英文摘要:

This study introduces a novel approach to autonomous motion planning, informing an analytical algorithm with a reinforcement learning (RL) agent within a Frenet coordinate system. The combination directly addresses the challenges of adaptability and safety in autonomous driving. Motion planning algorithms are essential for navigating dynamic and complex scenarios. Traditional methods, however, lack the flexibility required for unpredictable environments, whereas machine learning techniques, particularly reinforcement learning (RL), offer adaptability but suffer from instability and a lack of explainability. Our unique solution synergizes the predictability and stability of traditional motion planning algorithms with the dynamic adaptability of RL, resulting in a system that efficiently manages complex situations and adapts to changing environmental conditions. Evaluation of our integrated approach shows a significant reduction in collisions, improved risk management, and improved goal success rates across multiple scenarios. The code used in this research is publicly available as open-source software and can be accessed at the following link: https://github.com/TUM-AVS/Frenetix-RL.
