Research on Longitudinal Tracking Control for a Simulated Intelligent Vehicle Platoon

Intelligent vehicle platoon driving is a process of flexible control based on the coordination between vehicle and highway in intelligent vehicle-highway system. It can improve the velocities and reduce the spacing between vehicles in the platoon, thus, to improve road capacity and road safety. It is the most important for developing intelligent vehicle-highway system to construct intelligent vehicle platoon driving simulation experiment system by means of one tenth of model cars, simulated road and the technology of intelligent control and wireless communication. In order to simulate a platoon of intelligent vehicles traveling, first, the acceleration information has been added to control single vehicle, and the controller for velocity tracking based on acceleration has been designed using fuzzy sliding mode control method, then it is designed a longitudinal tracking controller for double vehicles by building a second-order plant model about longitudinal relative distance using the acceleration and velocity as well as the displacement information. Finally, the good track performance of the two controllers for both single vehicle and double vehicles is illustrated by simulation results, which can promote the study in the intelligent vehicle platoon control under the coordination between vehicle and highway.
