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, based on a calculation of a parked direction of the vehicle, so as 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 parked direction of the vehicle; receiving a signal of a WiFi AP adjacent to a parked 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 parked 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 included in a WiFi AP database, measuring an RSSI value of the signal of each of the WiFi APs using a response to the transmitted loopback signals; correcting the measured RSSI values using the beam pattern data; re-calculating a lattice position of each WiFi AP in the WiFi AP database using the corrected RSSI values; and calculating a position of the terminal on the basis of the position of the WiFi AP adjacent to the terminal, wherein the beam pattern data is based on calculation of a parked direction of the vehicle.
