  Abstract

It is necessary to localize train accurately for the train control in the train control system. In the train movement, the displacement is calculated by multiplying time by the train speed measured by tachometer. In this process, there exists the time difference between the reception of speed information and the calculation of the displacement. Moreover, this time difference (deviation) is not uniform. Hence, error in the calculated displacement occur and this results in inaccurate localization. In this study, we propose a displacement calculation method with the estimated speed at the half-time point using the time difference information and the estimated train acceleration. Computer simulation for the constant speed movement and constant deceleration movement is performed, and the real track test where both conventional and proposed method are executed in the real train is performed as well. The simulation and the real test show the effectiveness and the superiority of the proposed method.
