本文提出VDD方法,通过分离车辆动力学与环境动力学建模,提升自动驾驶中对车辆参数变化的鲁棒性。

摘要:

世界模型在自动驾驶领域获得了广泛关注,因其能够模仿人类般的感知和决策过程,从而预测并适应动态环境。现有方法通常将高维观测映射到紧凑的潜在空间,并在这些潜在表示中学习最优策略。然而,先前的工作通常从图像输入中联合学习车辆自身动力学和环境转换动力学,导致效率低下且缺乏对车辆动力学变化的鲁棒性。为了解决这些问题,我们提出了嵌入车辆动力学的Dreamer(VDD)方法,将车辆自身动力学建模与环境转换动力学建模分离。这种分离使世界模型能够有效泛化到具有不同参数的车辆。此外,我们引入了两种策略以进一步增强学习到的策略的鲁棒性:部署期间的策略调整(PAD)和训练期间的策略增强(PAT)。在模拟环境中进行的全面实验表明,所提出的模型显著提高了驾驶性能和对车辆动力学变化的鲁棒性,优于现有方法。

英文摘要:

World models have gained significant attention as a promising approach for autonomous driving. By emulating human-like perception and decision-making processes, these models can predict and adapt to dynamic environments. Existing methods typically map high-dimensional observations into compact latent spaces and learn optimal policies within these latent representations. However, prior work usually jointly learns ego-vehicle dynamics and environmental transition dynamics from the image input, leading to inefficiencies and a lack of robustness to variations in vehicle dynamics. To address these issues, we propose the Vehicle Dynamics embedded Dreamer (VDD) method, which decouples the modeling of ego-vehicle dynamics from environmental transition dynamics. This separation allows the world model to generalize effectively across vehicles with diverse parameters. Additionally, we introduce two strategies to further enhance the robustness of the learned policy: Policy Adjustment during Deployment (PAD) and Policy Augmentation during Training (PAT). Comprehensive experiments in simulated environments demonstrate that the proposed model significantly improves both driving performance and robustness to variations in vehicle dynamics, outperforming existing approaches.
