Abstract :
In this paper, a longitudinal switching control of autonomous platoon is investigated. Firstly, the switching control model is established by considering the variation of the relative velocity between following vehicle and preceding vehicle. Then, the dynamic models with the relative velocity and spacing error are given by according to the response delay and transmission delay´s influence on the parameters of vehicles, and the string stability is analyzed under the control parameters meeting certain conditions. Finally, the simulation results show that the proposed switch control method make an autonomous platoon maintain a safe distance.
