1. A vehicle position recognizing apparatus comprising:
- a WiFi module configured to receive signals from a plurality of WiFi access points (APs);
a WiFi positioning system (WPS) module configured to measure received signal strength indicator (RSSI) values of the signals received by the WiFi module, and estimate a position of a vehicle; and
a WPS correction controller configured to correct the RSSI values measured by the WPS module to recognize the position of the vehicle.

Abstract
The present invention relates to an apparatus and method for recognizing a position of a vehicle to notify the position to a driver. The vehicle position recognizing apparatus includes a WiFi module configured to receive signals from a plurality of WiFi APs, a WPS module configured to measure RSSI values of the signals received by the WiFi module, and estimate a position of a vehicle, and a WPS correction controller configured to correct the RSSI values measured by the WPS module to recognize the position of the vehicle.

9. A vehicle position recognizing method comprising:
-
determining whether a vehicle is parked and calculating a parking direction of the vehicle; receiving a signal of a WiFi AP adjacent to a parking position of the vehicle to collect WiFi AP information; measuring an RSSI value of the received signal of the WiFi AP and correcting the measured RSSI value; calculating the parking position of the vehicle by applying the corrected RSSI value of the signal of the WiFi AP to a WiFi AP database; and transmitting parking position information of the vehicle. - View Dependent Claims (10, 11, 12, 13, 14)

15. A terminal position recognizing method comprising:
-
obtaining beam pattern data of an antenna installed in a terminal; receiving a signal of a WiFi AP adjacent to the terminal, transmitting a loopback signal for each WiFi AP, measuring an RSSI value of the signal of the WiFi AP using a response to the loopback signal of the WiFi AP; correcting the measured RSSI value using the beam pattern data of the antenna; re-calculating a lattice position of a WiFi AP database using the corrected RSSI value; and calculating a position of the terminal on the basis of the a position of the WiFi AP.
