Research of an Intelligent Connected Vehicle Collaborative Car-Following Model Based on Ecological Driving
In order to improve road capacity and reduce energy consumption,this paper introduces a collabora-tive following system based on intelligent connected vehicle ecological driving.The collaborative vehicle following model consists of three levels:perception layer,decision-making layer,and control layer.The control strategy com-bines vehicle dynamics with wireless communication technology to achieve perception,control and obtain surround-ing information in a simulated complex traffic environment.It integrates a predictive control(MPC)strategy based on minimizing driving distance to improve the sustainability of traffic flow.The performance of the ecological driv-ing controller is achieved through the evaluation of fuel consumption and emissions based on two state variables:ve-hicle speed and acceleration.Finally,the dynamic characteristics of the controller are verified,which are embodied in three aspects:car following behavior,fuel efficiency improvement and carbon emission reduce.The proposed con-troller can effectively reduce fuel consumption and emissions during the following process.
