Document Type and Number:
WIPO Patent Application WO/2020/217724
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve the availability of a technique for estimating the self-position of a train using an identifier outside the rail. A self-position estimation means for estimating a self-position from the position information of an identifier installed outside the rail and a relative distance between the identifier and a train is characterized by, when it is impossible to recognize a first identifier in a traveling direction, recognizing a second identifier using a sensor on the opposite side to the traveling direction to estimate the self-position of the train from the position information of the second identifier.
