Hardware-in-the-loop Simulation Tool for Connected Vehicle Technology Evaluation

Project Abstract: 

The two fundamental challenges related to the connected vehicle highway system are necessity of phased deployment (because such a system cannot be built overnight) and high system complexity due to the number and types of vehicles, communication devices, and road conditions involved. The aim of this project is the development of new approaches for testing connected vehicle technologies safely and economically. The project will develop a hardware-in-the-loop simulation (HiLS) system that integrates vehicular traffic/wireless communication simulation models with a rapid prototyping powertrain research platform and a signal control cabinet. As far as the researchers are aware, the proposed HiLS testbed is the first attempt to integrate a microscopic traffic simulation with a laboratory powertrain research platform and real-time traffic signals. In this testbed, real-time traffic signals from a test site will feed into a microscopic traffic model to set the background traffic. The traffic simulation is coupled with a wireless communication network model to evaluate the performance of information transmission between vehicles (vehicle-to-vehicle (V2V)) and between vehicles and infrastructure (vehicle-to-infrastructure (V2I)). From the simulated traffic stream, a particular vehicle can be selected and its power demand sent in real-time to the powertrain research platform, where an actual engine in the laboratory will be operated to emulate thevehicle motion.


The objective of this project is to build a hardware-in-the-loop simulation (HiLS) testbed to test and assess the performance of connected vehicles applications.
