Claim 10:
11. 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 configured to 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, and wherein
the state estimating part is configured to estimating the state of the magnetic detecting part based on the state of the plurality of magnetic markers, and
the server apparatus includes a sensor information providing part which provides sensor state information indicating the state of the magnetic detecting part to a vehicle side.
