Study on Collaborative Control Method of Vehicle Platooning Based on Edge Intelligence
With the development of communication technology and automatic control technology,the autonomous control method of intelligent and connected vehicles(ICV),especially the control method under hybrid platooning,has become an important direc-tion of the research of unmanned driving technology.In order to reduce the delay of control strategy output due to the limitation of computing power of on-board processor,and improve vehicle tracking effect,a collaborative control method of vehicle platoo-ning based on edge intelligence is proposed.Using the powerful computing power of edge server and 5G communication network,a control system based on edge intelligence is designed to upload computing tasks to the cloud and release the computing re-sources of the on-board processor.Based on the analysis of vehicle following scenario in hybrid platooning,a vehicle platooning control model in spatiotemporal coupling scenario is designed,and a vehicle dynamics model is established by using MPC control algorithm.Through model prediction,rolling optimization and feedback correction,control strategy calculation services are provi-ded for intelligent and connected vehicle.The results of MATLAB simulation experiment and edge computing virtual platform ex-periment show that the proposed MPC control algorithm performs well in trajectory tracking control and can provide safety con-trol strategy for vehicles in real time and efficiently.
