Abstract
In a magnetic marker system including a magnetic marker disposed in a travel environment so as to be detectable by a magnetic sensor attached to a vehicle and a server apparatus which acquires detection information of the magnetic marker from each vehicle, the detection information uploaded from a vehicle side to the server apparatus includes marker information, which is identification information of a corresponding magnetic marker, and the server apparatus estimates the state of the magnetic marker based on the detection information from each vehicle.
Claims16
A magnetic marker system including a plurality of magnetic markers laid in or on a traveling road so as to be detectable by a magnetic detecting part attached to a vehicle, the system comprising:
- vehicles each of which outputs, when detecting a magnetic marker of the plurality of magnetic markers, detection information including marker identifying information capable of uniquely identifying the magnetic marker;
- and
- a server apparatus which acquires the detection information outputted from each of the vehicles, wherein
- the server apparatus includes a state estimating part which estimates a state of the magnetic marker based on a plurality of the detection information regarding the magnetic marker.
