Title:
MAGNETIC MARKER, VEHICULAR SYSTEM, AND MARKER DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/243617
Kind Code:
A1
Abstract:
This magnetic marker (10), which is disposed at distance along a travel path (1R) so as to be detectable during a movement of a vehicle, is a multiple-pole magnetic marker (10B) which is one magnetic marker composed of a plurality of magnet pieces (100) which are arranged so as to have magnetic polarities alternately different from each other. The multiple-pole magnetic marker (10B) can be detected with high reliability by detecting, on the vehicle side, a magnetism change which periodically and repetitively changes, the number of times of the periodic repetition corresponding to the number of the plurality of magnet pieces (100).
