In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view schematically showing the configuration of a vehicle parking position guide system according to an embodiment of the present invention.

As shown in FIG. 1, the vehicle parking location guide system according to the present embodiment includes a vehicle parking location manager 110 and a portable terminal 130. The vehicle parking location manager 110 is mounted on a vehicle to perform near field communication with the portable terminal 130. The portable terminal 130 is a portable terminal such as a mobile communication terminal, PDA.

Referring to FIG. 1, the vehicle parking position manager 110 may include a shift lever detector 111, a controller 113, and a short range communication unit 115.

The shift lever detecting unit 111 detects a shift lever state of the vehicle and transmits a detection signal regarding the shift lever to the control unit 113 when the shift lever is located in the parking mode P or the driving mode D. Preferably, the shift lever detecting unit 111 includes a Data Link Connector (DLC) port connected to the ECU (Electronic Control Unit) of the vehicle and detects a state of the shift lever through the DLC port.

The control unit 113 receives a detection signal for the shift lever from the shift lever detecting unit 111, and transmits a location storing command or a location deleting command to the portable terminal 130 according to the received detection signal. Specifically, when the control unit 113 receives the parking mode detection signal of the shift lever from the shift lever detecting unit 111, transmits a current position storing command to the mobile terminal 130, and the shift lever from the shift lever detecting unit 111. When receiving the driving mode detection signal of the mobile terminal 130 transmits a location deletion command instructing to delete the stored current location.

The short range communication unit 115 performs short range communication with the short range communication unit 131 of the mobile terminal 130 and transmits a location storing command or a location deleting command transmitted from the control unit 113 to the mobile terminal 130. Examples of short range communication include, but are not limited to, Bluetooth, ZigBee, and the like.

Meanwhile, referring to FIG. 1, the portable terminal 130 includes a short range communication unit 131, an input unit 132, a control unit 133, a position measuring unit 135, a memory 137, a display unit 138, and an audio output. Section 139.

The local area communication unit 131 communicates with the local area communication unit 115 of the vehicle parking location manager 110 to receive a location storage command or a location deletion command.

The input unit 132 receives an operation signal for operating the mobile terminal 130 from the user and transmits it to the control unit 133. The input unit 132 may be a keypad or a touch pad. In the present invention, the input unit 132 receives the parking position guide input from the user and transmits it to the control unit 133.

The position measuring unit 135 measures the current position of the mobile terminal 130 under the control of the controller 133. The location measuring unit 135 incorporates a GPS receiver to measure the current location of the mobile terminal 130 using a GPS satellite signal.

The memory 137 stores various data and programs necessary for the operation of the portable terminal 130. In the present invention, the memory 137 stores a program for guiding a parking location route, map data, and parking location information.

The display unit 138 is a liquid crystal display (LCD) or the like and displays state information of the mobile terminal 130, an interface screen of a program driven in the mobile terminal 130, and the like. In the present invention, the display unit 138 displays the parking location guide map under the control of the controller 133 to provide a parking location guide screen.

The voice output unit 139 outputs a guidement at the time of guiding parking position under the control of the controller 133.

The controller 133 controls the overall operation of the mobile terminal 130. The control unit 133 instructs the position measuring unit 135 to measure the position when the parking position storing command is received through the short range communication unit 131, and stores the position information measured by the position measuring unit 135 as the parking position information as a memory ( 137). In addition, the controller 133 deletes the parking location information stored in the memory 137 when the parking location deletion command is received through the short range communication unit 131.

In addition, when the user's parking position guide input is received through the input unit 132, the controller 133 measures the current position through the position measuring unit 135, and stores the measured current position information and the memory 137. The parking guidance logic is executed using the parking location information. The controller 133 drives a parking guide program stored in the memory 137 and displays a path screen from the current position to the parking position on the display unit 138 using the current position and the parking position information stored in the memory 137. Then, the route output message is output to the voice output unit 130.

As described with reference to FIG. 1, when the shift lever of the vehicle is placed in the parking mode P, the parking position information is stored in the portable terminal 130, and the portable terminal 130 is then operated by the user according to the parking guidance input of the user. Route guidance from the current location to the place corresponding to the stored parking location information. In addition, when the user attempts to drive in a vehicle (that is, the shift lever is in the driving mode (D) state), the parking location information already stored in the mobile terminal 130 is deleted to allow the user to park in another place. This prevents confusion with the parking position information to be stored when being made.

The remote center 450 measures the position of the mobile terminal 430 through a plurality of repeaters or APs installed in various places of a large parking lot. For example, the position of the mobile terminal 430 is measured using a triangulation method or the like. When the route guidance request is received from the mobile terminal 430, the remote center 450 measures the current location of the mobile terminal 430 in real time and uses the measured current location and the parking location information received from the mobile terminal 430. To generate route guidance data and transmit the generated route guide data to the mobile terminal 430.

Referring to FIG. 4, when a parking position storage command is received through the short-range communication unit 131, the controller 431 of the portable terminal 430 sends the current parking position to the remote center 450 through the remote center communication unit 433. A measurement is requested, and parking location information is received from the remote center 450 and stored in the memory 137. That is, the portable terminal 430 measures the position of the portable terminal 430 at the time of parking of the vehicle and stores the measured position as parking position information.

In addition, when the control unit 431 of the portable terminal 430 receives the parking position route guidance input from the user through the input unit 132, the control unit 431 extracts the parking position information stored in the memory 137 and extracts the extracted parking position information. The parking location route guidance request message is transmitted to the remote center 450 through the remote center communication unit 433.

In addition, the control unit 431 of the mobile terminal 430 receives route guidance data (ie, map data and guidance) from the remote center 450 to the parking position from the current location of the mobile terminal 430 in real time. The map data is output to the display unit 138 and the guidance comment is output to the user through the voice output unit 139.

5 is a flowchart illustrating a method of storing parking position information in a portable terminal in the vehicle parking position guidance system of FIG. 4.

Referring to FIG. 5, the vehicle parking position manager 110 mounted on the vehicle detects a state of a shift lever of the vehicle (S501).
