Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a method and system for providing parking information. More particularly, the present invention relates to a method and system for displaying a graphical user interface in which parking information adjacent to a current position of a driver is mapped to a prepared virtual map, The present invention relates to a method and system for providing parking lot information, which can provide optimal parking lot information, which is a parking lot that can be parked when a vehicle arrives at a parking lot, using a current position, distance to a parking lot, speed,

A parking lot is a place to provide parking spaces for a large number of vehicles in a specific space. Since a limited number of vehicles can be parked in a limited space, traffic congestion and exhaust gas pollution are generated In particular, since there is no way for the driver to know the information about the specific parking lot in advance, the driver of the vehicle can recognize the information even if there is no parking space at the desired destination, so that unnecessary time and fuel consumption . ≪ / RTI >

Accordingly, various studies are being conducted on a parking information providing system in which parking lot information, which is information on a parking lot adjacent to a current position of the vehicle, is provided to a vehicle driver so that a driver of the vehicle recognizes information on an adjacent parking lot in advance.

In Korean Patent Publication No. 2000-0060943 (entitled "Parking lot guide device and guidance method"), data on the number of vehicles in the parking lot and the number of the parking lot are displayed on the parking information plate, A parking guide device for recognizing the parking lot in advance is described.

However, since the parking lot guide apparatus simply provides information on a specific parking lot at a specific location, the driver of the vehicle can not receive parking information according to his / her location in advance, and in order to receive information on a specific parking lot, It is necessary to directly move to the place where the plate is installed.

In Korean Patent Laid-Open No. 1999-011004 (entitled " Parking lot guidance system and method "), a parking lot guidance system for guiding an optimal parking lot existing in a shortest path from a current position of a vehicle to a driver is described. When the parking lot information is requested from the driver, provides optimum parking lot information and a moving path for moving to the corresponding parking lot according to the distance from the current position of the driver, the average driving time from the current position of the driver to the parking lot, do.

However, in a parking lot having a large number of moving vehicles, the number of available parking spaces greatly fluctuates in real time because of a large number of entrance and departure. However, the parking lot guide system can not store data at a specific time, Accordingly, even if the driver of the vehicle moves to the corresponding parking lot, the provided parking lot information and the actual parking lot information do not coincide with each other.

In addition, the parking lot guide system determines the optimal parking lot without considering the tilt increase rate data and the time required for the vehicle driver to move to the parking lot when the rate of increase of the entrance of the optimal parking lot is high. Even if the parking lot is moved to the provided parking lot, there is a problem that the parking lot is full because the increase rate of the entrance is high.

For example, the 'A' parking lot is located 300m from the current location (P) of the driver, the 'B' parking lot is located 600m away, the change rate of the available parking space per minute of the 'A' parking lot is '-10' The number of available parking spaces is changed to '1', the current number of available parking spaces is 5, the driver moves to 'A' parking lot for 4 minutes, the parking lot for 'B' The optimum parking lot is determined according to the distance from the current position of the parking lot guidance system driver, the average driving time from the current position of the driver to the parking lot, and the number of available parking spaces. The number of parking spaces that can be parked when the driver moves to the 'A' parking lot after 4 minutes is '0' because the current increase rate of the 'A' parking lot is high, Increase in inflow Rather, when the driver moved to 'B' parking after 8 minutes because of a lower right are able to park in their parking lot.

In order to solve the problem of the parking lot guidance system, parking lot information, which is periodically updated, Service system, the parking service system updates and displays only the real-time parking information without considering the rate of change of the available parking space. Accordingly, the driver simply displays the parking information displayed while driving, There is a limit to determine the appropriate parking lot directly.

In this way, it is urgently required to provide a parking lot information providing system that provides the parking lot information adjacent to the current position of the driver to the driver in real time, and provides the optimal parking lot according to the rate of change of the available parking space of each parking lot and the distance to the vehicle .

If the predicted parking availability number I is less than the set value TH, the adjacent parking lot is excluded.

If the number of the parking lots determined as the optimum parking lot by the optimal parking determination unit 43 is one, the final optimal parking determination unit 44 finally determines the corresponding parking lot as the optimal parking lot.

If the number of the parking lots determined as the optimal parking lot by the optimal parking determination unit 43, the final optimal parking determination unit 44 determines the corresponding parking lots in the order in which the predicted required time t is small or in the order in which the parking fee is small And the parking lot with the highest priority is finally determined as the optimum parking lot. In the present invention, for convenience of explanation, the final optimal parking determination unit 44 has been described as giving priorities according to any one of the order in which the predicted required time t is small or the parking fee is low , The method of selecting the priority is not limited thereto, and various methods may be applied according to the administrator's selection.

The optimum movement path detecting unit 45 detects an optimum movement path corresponding to the current position of the driver and the optimal parking lot determined by the final optimal parking determination unit 44 according to the travel route detection algorithm stored by the database unit 32 .

At this time, the detected optimal travel route information is transmitted to the parking information applications 6-1, ..., 6-N according to the control of the control unit 31. [
