Ali Bemani, Niclas Bjorsell

摘要:

车-车、车-基础设施互联系统可以看作是一个无线信息物理系统(Wireless CPSoS),它将具有系统的高度自适应控制能力、无线CPSoS控制的协同场景和自适应无线网络控制系统(WNCS)。在本文中,我们提出了我们的多车辆测试平台的基础上的信息物理系统,设计用于验证和验证的协同驾驶算法,涉及WNCS测试。车辆被开发为配备Raspberry-pi微处理器和其他传感元件的物理原型。该试验台由4辆机器人车辆组成。利用惯性测量单元(IMU)和基于蓝牙低功耗技术的iBeacon,设计了一种基于粒子滤波的室内定位系统(IPS)。在该实验平台上可以实现一些典型的室内协同驾驶场景。采用基于卡尔曼滤波器(KF)的状态观测器的模型预测控制(MPC)实现目标状态。因为无线控制系统可能受到无线通信链路的缺陷的严重影响。该实验平台为将来采用新的无线技术和控制系统测试和评估更智能的协同驾驶场景铺平了道路。

英文摘要:

The system of connected vehicle to vehicle and vehicle to infrastructure can be considered as a wireless cyberphysical system of systems (Wireless CPSoS), which will be provided with the high ability of adaptive control on system of systems, cooperative scenarios to control of a Wireless CPSoS and adaptive wireless networked control system (WNCS). In this paper we present our multi-vehicle testbed based on the cyber-physical system that was designed for verification and validation of cooperative driving algorithm involving WNCS testing. Vehicles were developed as the physical prototype equipped with Raspberry-pi microprocessor and other sensing elements. This testbed consists of a fleet of 4 robot vehicles. An indoor positioning system (IPS) based on particle filter is purposed by using an inertial measurement unit (IMU) and iBeacon that is built upon Bluetooth Low Energy. Some typical cooperative driving scenarios can be implemented on this testbed under indoor laboratory. The method used to realize the objective statement was Model Predictive Control (MPC) with a state observer based on a Kalman Filter (KF). Because the wireless control systems can be severely affected by the imperfections of the wireless communication link. Our experimental testbed paves the way for testing and evaluating more intelligent cooperative driving scenario with the use new wireless technology and control system in the future.
