摘要:

基础设施支持自主性(IEA)是一种新范式,通过将核心功能卸载到基础设施,为互联自动驾驶汽车采用分布式智能架构。在本文中,我们开发了一个模拟框架,可用于研究的概念。这种模拟的一个关键挑战是,随着要考虑的基础设施的规模,计算规模迅速增加。我们的模拟框架被设计成分布式的,并与基础设施成比例地扩展。通过集成使用硬件控制器和通信设备作为仿真框架的一部分,我们实现了动态和传感器建模之间的最佳平衡,并重用真实硬件来模拟专有或复杂的通信方法。模拟基础设施上的多个摄像机。摄像机图像处理的模拟在分布式硬件中完成,并且所得到的位置信息被无线传输到模拟自主车辆的计算机。我们演示了一个单一的车辆闭环控制以下给定的航路点,使用来自多个摄像机位于路边单位的信息。

英文摘要:

Infrastructure Enabled Autonomy (IEA) is a new paradigm that employs a distributed intelligence architecture for connected autonomous vehicles by offloading core functionalities to the infrastructure. In this paper, we develop a simulation framework that can be used to study the concept. A key challenge for such a simulation is the rapid increase in the scale of the computations with the size of the infrastructure to be considered. Our simulation framework is designed to be distributed and scales proportionally with the infrastructure. By integrally using both the hardware controllers and communication devices as part of the simulation framework, we achieve an optimal balance between modeling of the dynamics and sensors, and reusing real hardware for simulation of proprietary or complex communication methods. Multiple cameras on the infrastructure are simulated. The simulation of the camera image processing is done in distributed hardware and the resultant position information is transmitted wirelessly to the computer simulating the autonomous vehicle. We demonstrate closed loop control of a single vehicle following given waypoints using information from multiple cameras located on Road-Side-Units.
