The present invention relates to a facility search method of a navigation system, and more particularly, to allow a user to set a facility frequently searched as a representative facility so that a user can quickly search for a destination when using a facility search for a destination search. The present invention relates to a method for navigating a facility of a navigation system, which enables a user to implement a navigation that is convenient for their use.

With the diversification of wireless mobile communication services, wireless mobile communication and location tracking systems are being combined with automobiles. In particular, the vehicle navigation system that provides real-time traffic information and guides traffic information services, and the remote vehicle that informs the presence of vehicle abnormalities. There is a growing interest in telematics services that are intended to integrate diagnostics, vehicle location tracking using GPS, and additional information services that provide various information services.

The telematics system is provided in a vehicle and provides various computing functions as well as functions as a terminal for receiving various information, and a location-based information service that detects vehicle location from a control center (information center) and informs surrounding information, and a car. Remote vehicle diagnosis service that checks and controls the vehicle status by connecting the electronic control device of the vehicle, the vehicle diagnostic equipment, and the terminal to the control center, and provides a navigation service that provides traffic information to the desired destination of the driver. It will be included.

Looking at the navigation service in detail, it determines the optimal route from the starting point to the destination at the request of the user and provides the result to the user. To this end, the navigation server (information center) determines the route using the departure and destination information of the navigation vehicle and the current traffic information at the time of departure. However, when conducting route guidance from the departure point to the arrival point using the traffic information at the departure point, the traffic information after the lapse of the driving time cannot be considered, and therefore, the dynamic route guidance cannot be performed. The disadvantage is that the accuracy of the estimated arrival time is poor. In order to make up for this drawback, in recent years, updated traffic information such as accidents and weather are used to periodically plan the route while driving and to induce changes.

On the other hand, in a conventional navigation system, a facility search function may be used to search for a destination. Here, the facility search function is a function for selecting a facility such as a government office, an airport, a department store, and searching for a desired destination.

As shown in FIG. 1, a facility that is expected to be used by a user among a plurality of searchable facilities is set as a representative facility, and when a facility search is started, a representative facility that is set in advance is basically displayed first to quickly select a representative facility. Is implemented.

However, such a conventional navigation system has a problem in that it takes a long time to select a desired facility when a user who does not frequently search for a facility that is set as a representative facility because all the facilities frequently searched for each user is different.

Therefore, the present invention has been proposed to solve the above problems, it is possible to set up a facility that the user frequently searches as a representative facility when using the facility search for the destination search facility search of the navigation system to enable a fast destination search The purpose is to provide a method.

Another object of the present invention is to provide a facility search method of a navigation system that enables a user to implement a navigation that is convenient for use.

Features of the facility search method of the navigation system according to the present invention for achieving the above object,

Setting a facility frequently searched by a user as a representative facility;

A second step of checking whether a facility set by the user exists when a destination setting is selected by the user and a facility search is requested;

As a result of the checking, if the user-specified facility exists, it is configured to include a third step of displaying the read facility as a representative facility for reading the facility quickly.

The first step in the facility search method of the navigation system according to the present invention,

After the user searches for a specific facility, the user requests input to the representative facility, or the user designates the reference number in advance and automatically sets the facility as the representative facility when the search for the corresponding facility becomes more than the reference number. .

In addition, the facility search method of the navigation system according to the present invention,

If the user-specified facility does not exist as a result of the checking of the second step, the method further comprises a fourth step of reading a preset basic facility and displaying the representative facility.

Other objects, features and advantages of the present invention will become apparent from the detailed description of the embodiments with reference to the accompanying drawings.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention. If it is determined that the detailed description of the known function or configuration related to the present invention may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

2 is a view showing the configuration of a vehicle navigation system to which the present invention is applied, wherein reference numeral 110 is a GPS receiver for receiving position information and a vehicle traveling speed from a GPS satellite, and includes a GPS antenna and the like. From the position information such as the position and angle and the driving speed information of the vehicle.

Reference numeral 120 is an input unit such as a touch screen and a keypad for generating a user operation signal according to a user's operation, and may input information for a rescan command, and may generally be configured as a keypad device such as a keyboard for user operation. However, when the touch screen is configured, the touch screen is configured to be linked with the display device, which is a display device.

Reference numeral 130 denotes a memory in which an application program for operating a navigation system is stored, and a facility designated by a user is stored or a predetermined basic facility is stored.

Reference numeral 140 controls the overall operation of the vehicle navigation system, but sets the facility arbitrarily designated by the user as a representative facility, and if the facility search is used to search for a destination, the representative facility is set if the user has a randomly set representative facility. Displays a control unit that displays the facility and controls the user to quickly search for the desired facility. Herein, the control unit 140 represents a conventional central processing unit (CPU) or a microprocessor.

Reference numeral 150 denotes a map database (DB) for outputting map information of a stored road network, reference numeral 160 denotes a facility database in which facility information is stored, and reference numeral 170 denotes a facility mainly searched by a user according to a user's request. A facility setting unit for setting as a facility and storing in the memory 130 is shown.

Reference numeral 180 denotes a display unit for displaying a starting point, a destination, and the like, a route currently in progress, traffic information, parking lot location information, road information, representative facilities, and the like, under the control of the controller 140. A voice output unit for outputting a voice required for setting and guiding through the speaker 191.

3 is a flowchart illustrating a facility search method of a navigation system according to the present invention, the first step of setting a facility frequently searched by a user as a representative facility (S101); A second step (S103 to S107) of checking whether a facility set by the user exists when a destination setting is selected by the user and a facility search is requested; A third step (S109 to S111) of reading out the facility designated by the user, if it exists, and displaying the read facility as a representative facility for quick facility search; If the user-specified facility does not exist as a result of the checking of the second step, the fourth step (S113, S111) is performed to read the preset basic facility and display it as the representative facility.

In this way, the facility search method of the navigation system according to the present invention, first, the command that the user who has driven the navigation system via the input unit 120 to command to set the facility as a representative facility or to automatically set as a representative facility When the number of searches for the user is input, as in step S101, the controller 140 stores the corresponding information in the memory 130 and controls the facility setting unit 170 to set the search facility as the representative facility according to the user's requirements. Will be released.

For example, when a user sets a representative facility through an input command, after completing a specific facility search and requesting a representative facility input, the facility setting unit 170 stores the search facility as the representative facility in memory 130. Will be stored in. If the user sets the number of searches by another method, if the control unit 140 searches for a specific facility, the facility setting unit 170 may be searched only when the number of searches of the facility is searched to be equal to or more than the number of searches set by the user. Through the search facility is stored in the memory 130 as a representative facility.

In this way, when the user sets the facility frequently searched as the representative facility, when the user selects the destination setting as in step S103 and the facility search is requested as in step S105, the facility designated by the user is set in step S107. Check if it exists.

As a result of this check, if there is no facility separately designated by the user, the process proceeds to step S113 to read basic facility information from the memory 130, and displays the read basic facility as a representative facility in step S111. This method is the same as the conventional facility search method.

On the contrary, if a user-specified facility exists, the process moves to step S109 to read a user-specified facility that the user separately designates and stores from the memory 130. Thereafter, in step S111, the facility designated by the user is displayed on the display unit 180 as a representative facility.

This allows users to quickly navigate the facilities they frequently search, thereby enabling the navigation of the optimal user environment.

As described above, the facility search method of the navigation system according to the present invention can set a facility mainly searched by a user as a representative facility, thereby enabling the user to quickly search for a facility mainly searched by. There is.
