APPARATUS AND METHOD FOR DETECTING VEHICLE
First Claim
1. An apparatus for detecting and classifying a vehicle, the apparatus comprising:
- a database (DB) configured to store information regarding a magnetic signal change pattern with respect to each vehicle;
a learning unit configured to update information regarding the magnetic signal change pattern with respect to each vehicle through learning;
a magnetic signal obtaining unit configured to obtain a magnetic signal from strength of a geomagnetic field generated due to a movement of a vehicle; and
a detection unit configured to detect and classify a moving vehicle on the basis of information regarding the latest magnetic signal change pattern indicating a change in the magnetic signal and information regarding the magnetic signal change pattern with respect to each vehicle stored in the DB.

Abstract
A vehicle detecting apparatus obtains a magnetic signal from strength of a geomagnetic field generated due to a movement of a vehicle, and detects and classifies the moving vehicle on the basis of information regarding the latest magnetic signal change pattern indicating a change in the magnetic signal and information regarding a magnetic signal change pattern with respect to each vehicle stored in a database. The vehicle detecting apparatus receives detection and classification information regarding a vehicle which has actually moved, from an external information providing server, and gradually updates it through learning of a magnetic signal change pattern of the corresponding vehicle.
