Classification: CPC G  B | IPC B  G

Claim 2:
3. The vehicle in claim 1, wherein:
the computer processor is configured to diagnose a change in ground clearance of the vehicle in accordance with a change in mount height of the magnetic sensor in the vehicle,
the marker state information includes information indicating a magnetic level of the magnetic marker, and
the computer processor performs diagnosis of detecting the change in ground clearance of the vehicle by using an index value indicating a correlation between the magnetic level of the magnetic marker included in the marker state information and a peak value of a magnetic measurement value measured by the magnetic sensor for the magnetic marker, and
the index value indicating the correlation is a gradient of an approximate straight line of the correlation, and the computer processor performs a threshold process regarding temporal changes of the gradient of the approximate straight line and generates vehicle information indicating that the change in ground clearance of the vehicle is large when the temporal changes exceed a threshold value.
