This paper proposes a predictive constant time headway spacing strategy (PCTHS) for the heterogeneous vehicle platoon control problem. This strategy uses the vehicle’s own speed information and the speed information of the leader vehicle associated with the time headway to improve the driving safety and stability of the vehicles in the platoon. Based on the proposed PCTHS, a corresponding vehicle-following control protocol is designed. The proposed control protocol has a flexible general frame structure, which can not only realize the consensus of the position, velocity and acceleration of heterogeneous vehicles in the platoon, but also effectively reduce the unreasonable acceleration/deceleration of vehicles, so as to ensure the comfort of vehicles during driving. Then, the stability conditions are obtained by performing state linear transformation and partial stability theory analysis on the vehicle platoon system. Finally, the effectiveness of the proposed method is verified by the simulation of a third-order heterogeneous vehicle platoon.
