Position Detection System Using GPS for Carbody Tilt Control

Abstract

By using the global positioning system (GPS), a novel train detection system has been established to assist trains with carbody tilt control. Japanese tilting trains can be equipped with an onboard database to store the current location and track conditions, thereby controlling the body tilt angle. This paper describes method to detect a train current position precisely by a combination of GPS and curvature collation, using the onboard database. This system was subjected to a running test to prove that its positional error was less than four meters.
