Abstract: In order to discuss and analyze the hot concept, vehicular CPS (Cyber Physical System), where CPS is an emerging and complex system that can obtain the physical status of vehicles and traffic environment, upload the information to cyber layer, and obtain better operating effect and performance level beyond the traditional transportation system, a novel intelligent vehicle car-following model based on CPS (IVCFM-CPS) is presented. Considering car following process, intelligent vehicles receive the recommended information that the previous and current traffic information and the vehicles’ states are analyzed and optimized in cyber layer, IVCFM-CPS is constructed and used to analyze intelligent vehicle car-following behavior under CPS environment, and the linear stability conditions through the comparison among different car-following models are also analyzed. Furthermore, to testify the theoretical conclusion, numerical simulations were conducted in MATLAB to analyze the impact of penetration rate of intelligent vehicles based on CPS on stability under mixed traffic flow. Results have illustrated the proposed IVCFM-CPS is capable of dealing with intelligent vehicle car-following behavior under CPS environment, and can provide novel insights into the complex and heterogeneous CPS.
