Claim 7:
8. The method of claim 7, further including:
after determining whether the difference value belongs to the predetermined threshold range,
determining, by the controller, whether the position at which the value of the gravity acceleration is measured matches road condition information when the controller concludes that the difference value is out of the predetermined threshold range as the result of the determining,
in the determining of the road as being in the abnormal condition,
when the controller concludes that the position at which the value of the gravity acceleration is measured does not match the road condition information as the result of the determining, determining, by the controller, the road corresponding to the position at which the value of the gravity acceleration is measured as being in the abnormal condition,
wherein the road condition information includes at least one of information among road slopes, curved sections, unpaved sections, manholes, road protrusions and depressions, and speed bumps.
