Patent ID: 8711003

Claim:
A system which determines an abnormal driving state of a vehicle, the system comprising: a sensing unit configured to include at least one sensor and sense a driving situation of a vehicle through the at least one sensor; a location information reception unit configured to receive location-based information of the vehicle; an operation statistic unit configured to calculate an acceptable range to be output by the sensing unit on a particular road based on the information detected by the sensing unit and the location-based information received by the location information reception unit; and an abnormal driving determination unit configured to compare values sensed by the sensing unit with values calculated by the operation statistic unit to determine whether or not the vehicle is driven in an abnormal state, wherein the acceptable range is criterion in which the abnormal driving determination unit determines a driving state of the vehicle, the acceptable range is divided into a high driving mode, a medium driving mode, and a low driving mode, and the abnormal driving determination unit determines a driving mode of the vehicle using the location-based information of the vehicle.
