Claim 6:
7. The vehicle in claim 1, including a history storage part which stores travel history data indicating a traveling route traveled by the vehicle and detection history data indicating a detection history of the magnetic marker, and
wherein the computer processor identifies a magnetic marker on the traveling route indicated by the travel history data and performs process of comparing the magnetic marker on the traveling route and the magnetic marker included in the detection history indicated by the detection history data, and
the computer processor determines a detection point representing a level of matching between the magnetic marker on the traveling route and the magnetic marker included in the detection history and performs a threshold process and determines that the magnetic sensor is normal when the detection point is equal to or larger than a threshold value and that the inspection of the magnetic sensor is required when the detection point is less than the threshold value.
