论文摘要
已经提出了车辆到所有的通信(V2X)通信,作为通过改善协调并消除非视线感应的障碍来提高自动驾驶汽车鲁棒性和安全性的潜在解决方案。合作车辆安全性(CVS)的应用密切取决于下面数据系统的可靠性,由于其不同组件的固有问题,例如传感器故障或在密集通信渠道负载下的V2X技术的性能差,可能会遭受信息损失。特别是,信息损失会影响目标分类模块,然后影响安全应用程序性能。为了启用可靠且稳健的CVS系统来减轻信息丢失的影响,我们提出了一个上下文感知的目标分类(CA-TC)模块,并与CVS系统的基于混合学习的预测建模技术相结合。 CA-TC由两个模块组成:上下文感知的地图(CAM)和混合高斯过程(HGP)预测系统。因此,车辆安全应用程序使用了CA-TC的信息,使其更加健壮和可靠。凸轮利用车辆路径历史,道路几何形状,跟踪和预测; HGP用于提供准确的车辆轨迹预测,以补偿数据丢失(由于通信拥塞)或传感器测量值的不准确性。基于离线现实世界数据,我们学习了一组有限的驾驶员模型,这些驱动程序模型代表了车辆的联合动态和驾驶员的行为。我们将离线培训和在线模型更新与在线预测相结合,以说明新的可能的驾驶员行为。最后,使用模拟和现实驾驶场景对我们的框架进行验证,以确认其在增强CVS系统鲁棒性和可靠性方面的潜力。
Vehicle-to-Everything (V2X) communication has been proposed as a potential solution to improve the robustness and safety of autonomous vehicles by improving coordination and removing the barrier of non-line-of-sight sensing. Cooperative Vehicle Safety (CVS) applications are tightly dependent on the reliability of the underneath data system, which can suffer from loss of information due to the inherent issues of their different components, such as sensors failures or the poor performance of V2X technologies under dense communication channel load. Particularly, information loss affects the target classification module and, subsequently, the safety application performance. To enable reliable and robust CVS systems that mitigate the effect of information loss, we proposed a Context-Aware Target Classification (CA-TC) module coupled with a hybrid learning-based predictive modeling technique for CVS systems. The CA-TC consists of two modules: A Context-Aware Map (CAM), and a Hybrid Gaussian Process (HGP) prediction system. Consequently, the vehicle safety applications use the information from the CA-TC, making them more robust and reliable. The CAM leverages vehicles path history, road geometry, tracking, and prediction; and the HGP is utilized to provide accurate vehicles' trajectory predictions to compensate for data loss (due to communication congestion) or sensor measurements' inaccuracies. Based on offline real-world data, we learn a finite bank of driver models that represent the joint dynamics of the vehicle and the drivers' behavior. We combine offline training and online model updates with on-the-fly forecasting to account for new possible driver behaviors. Finally, our framework is validated using simulation and realistic driving scenarios to confirm its potential in enhancing the robustness and reliability of CVS systems.
