A Study of Position Detection Method for Train Control Systems Using Inertial Sensors

Abstract

This paper propose an on-board position detection method using a combination of a tachometer and an inertial sensor to detect the beginning and end of curves and turnouts. As a result of the driving test, we obtained the prospect of achieving the target accuracy of position recognition error of 4m, which is to be used as a substitute of the position information ground beacon. This paper reports the outline of the proposal method and the test results.
