  • 适合自动驾驶中对安全性和可靠性要求高的场景。

精确的车辆状态估计对自动驾驶的安全可靠至关重要。车载传感器系统可测量的状态数量及其精度常受成本限制,例如当前光学传感器在商业上难以精确测量关键参数——车辆侧滑角(VSA)。本文通过构建高性能虚拟传感器来克服这些局限,提出了一种不确定性感知的混合学习架构(UAHL),直接从车载传感器数据中估计VSA。该架构的核心是量化单个模型预测及融合过程中的不确定性,实现对机器学习与车辆运动模型输出的动态加权,从而生成高精度、高可靠的混合式VSA估计。研究还构建了一个名为真实世界车辆状态估计数据集(ReV-StED)的新数据集,包含来自先进车辆动态传感器的同步测量数据。实验结果表明,所提方法在VSA估计上表现优异,验证了UAHL作为虚拟传感器先进架构的潜力,有助于提升自动驾驶中的主动安全性。

原文摘要 · Abstract (English)

Precise vehicle state estimation is crucial for safe and reliable autonomous driving. The number of measurable states and their precision offered by the onboard vehicle sensor system are often constrained by cost. For instance, measuring critical quantities such as the Vehicle Sideslip Angle (VSA) poses significant commercial challenges using current optical sensors. This paper addresses these limitations by focusing on the development of high-performance virtual sensors to enhance vehicle state estimation for active safety. The proposed Uncertainty-Aware Hybrid Learning (UAHL) architecture integrates a machine learning model with vehicle motion models to estimate VSA directly from onboard sensor data. A key aspect of the UAHL architecture is its focus on uncertainty quantification for individual model estimates and hybrid fusion. These mechanisms enable the dynamic weighting of uncertainty-aware predictions from machine learning and vehicle motion models to produce accurate and reliable hybrid VSA estimates. This work also presents a novel dataset named Real-world Vehicle State Estimation Dataset (ReV-StED), comprising synchronized measurements from advanced vehicle dynamic sensors. The experimental results demonstrate the superior performance of the proposed method for VSA estimation, highlighting UAHL as a promising architecture for advancing virtual sensors and enhancing active safety in autonomous vehicles.
