一种车路协同半实物仿真系统的设计与实现

Design and Implementation of a Vehicle-to-road Cooperation Hardware in Loop Simulation System

半实物仿真技术(hardware-in-the-loop simulation)是仿真实验中的新热点。基于半实物仿真系统的车辆编队实验是一种把实物车辆与计算机软件结合起来从而把现实环境中的各种复杂干扰量、突发事件、通信延时等因素引入到系统中的仿真实验。半实物仿真实验兼顾了实物仿真实验和软件仿真实验,既能比较真实地接近实际情况,又降低了实验成本和危险性。半实物仿真实验是车辆编队技术从理论走向应用过程中必不可少的重要设计验证手段之一。本实验室搭建了车路协同半实物仿真平台,在此平台上对典型交通场景下的车辆编队问题进行建模、仿真与控制等方面的实验研究。

Hardware-in-the-loop simulation is a new hot spot in simulation experiment.Vehicle platoon simulation system based on hardware-in-the-loop is a kind of simulation combined with vehicle and computer software so as to interfere with the amount of complex real-world environment in a variety of unexpected events,communication delay and other factors introduced into the system simulation experiments.Hardware-in-the-loop simulation taking into account both physical and and software simulation experiments,is relatively close to the real situation,and reduces the cost and risk of the experiment.It is an important means of vehicle platoon design verification technology from theory to application.The vehicle infrastructure cooperative hardware-in-the-loop simulation platform is built,where the problem of the vehicle platoon in typical traffic scenarios are researched on modelling,simulating and controling.
