Abstract

A magnetic marker detection system (1), for detecting, by using sensor units (11) disposed in at least two places separated from each other in a longitudinal direction of a vehicle (5), a magnetic marker (10) disposed in a traveling path, sets, when a magnetic marker has been detected by a front side sensor unit (11), a predetermined period including a predicted point of time of detection of the magnetic marker (10) by a rear side sensor unit (11) and makes, when the rear-side sensor unit (11) has successfully detected the magnetic marker (10) during the predetermined period, a determination that the magnetic marker (10) has been detected.
