Title:
MAGNETIC MARKER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/071182
Kind Code:
A1
Abstract:
Provided is a magnetic marker system (1) for implementing vehicle control either for assisting with driving operation of a vehicle performed by a driver or for autonomous driving independent of a driver's operation. Magnetic markers (10) are laid along a road such that the orientations of the magnetic poles thereof are alternately inverted, and are positioned with gaps therebetween along the road such that the magnetic fields of the adjacent magnetic markers (10) mutually interfere. Accordingly, detection reliability of vehicle-side magnetic markers (10) can be improved without the need to increase the magnetism of the magnetic markers (10).
