  Abstract

In this paper, we propose a protection algorithm for virtual coupler in train-to-train communication based autonomous train control system. For safe virtual connection and disconnection of moving trains, we propose a new allocation scheme for track resource that should be exclusively shared between the trains. The proposed shared resource allocation scheme merges so that a master train can own the track resources that are owned exclusively before virtual coupling. We propose the minimum safety distance between virtually coupled trains set which should be secured according to train characteristics and driving speeds, and propose a train braking model for virtual train coupling for this purpose. Simulation results show the changes of the minimum safety distance of the two trains before and after the coupling process, and the effect of train speed, communication, and delay of the braking system. Since the proposed protection algorithm in this paper for train-to-train communication based virtual train coupling does not use physical coupler, it can improve the flexibility of train operation and line capacity.
