BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation system, and in particular to a point of interest (POI) search method.

Recently, a lot of developments in navigation system is a system that provides a way to the destination where the user wants to go. In order for a user to be provided with directions, first, a user searches for a destination to go to.

Hereinafter, a conventional navigation system and a destination search apparatus will be described with reference to the drawings.

1 is a block diagram showing a conventional general navigation system.

Referring to FIG. 1, the GPS receiver 102 receives predetermined position data transmitted by a plurality of GPS satellites 100 through an antenna to receive a navigation service, and uses a velocity sensor / gyro sensor. 104 constitutes a sensor unit, which detects the rotation angle and the speed of the vehicle by the speed sensor / gyro sensor 104, respectively.

The input unit 106 is a user interface that receives various key signals from a user or sets a driving route.

The map data storage unit 108 stores map data and other additional information data. The map data storage unit 108 is generally implemented as a compact disk-read only memory (CD-ROM).

The controller 110 controls the overall operation of the navigation system.

To this end, the control unit 110 determines the current position of the moving object by the received signal of the GPS receiver 102 and refers to the determined current position of the moving object by referring to the map data stored in the map data storage unit 108 from the current position of the moving object. The driving route up to is searched for, and the searched driving route is displayed on the display unit 114 via the display driver 112 in an electronic map.

In addition, the driving path of the moving object is guided while outputting the guide voice to the speaker 118 through the voice guide unit 116.

The navigation system receives GPS satellite signals from a plurality of GPS satellites 100 disposed on the earth, and tracks the driving trajectory by grasping the current position and driving direction of the vehicle. It is a service that provides the vehicle driver with the shortest route to reach the destination through the driving route from the starting point.

2 is a view showing a procedure for searching for "Dongdaemun athletic field station" through the conventional destination search method.

In the conventional destination search system, a search condition of a destination is a region, an industry type, a name, and more specific steps include an area major classification, an area middle classification, an area sub classification, an industry classification, an industry classification, and a name input step.

First, the user selects the time unit to which the destination belongs in the regional major classification (S200), and selects the old unit to which the destination belongs in the regional middle classification (S202).

Then, the user again selects the copper unit to which the destination belongs in the sub-category (S204), selects the corresponding sector of the destination to find in the sector-specific classification (S206), and selects the corresponding classification from the sector sub-classification subdivided the sector. Select (S208).

Then, if the name of the destination is entered in the name input (S210), the search result of the destination search system comes out (S212).

For example, a process of using a conventional destination search method to search for "Dongdaemun Stadium" is as follows.

To search for "Dongdaemun Stadium" in the destination search condition classification window, select "Seoul" in the first large selection area (S200), and select "Dongdaemun-gu" in the second middle selection area (S202). In the sub-region, which is the third selection step, "Dapsimni 2-dong" is selected (S203).

Next, select "traffic" from the fourth category of industry classification (S206), select "station" from the fifth category of industry classification (S208), and "dongdaemun" to the name input step of the sixth step Enter (S210).

However, since the actual "Dongdaemun Playground" is located in Jung-gu, the user needs to go back to step 4 again to modify the "Dongdaemun-gu", which is the second selection step, to "Jung-gu".

In addition, if the user does not know which destination in Jung-gu, he can no longer proceed with the search.

In other words, the conventional destination search method requires all steps to produce a result, so if you want to modify the previous condition in the middle, you have to go back and start again, or select the local large category again.

The conventional destination search system not only inputs a condition according to a predetermined pattern, but also needs to input three conditions such as region, business type, name, etc., so that the user must know all the conditions in detail and search the conditions only in a certain order. The user has to spend a lot of time selecting all the conditions.

In addition, when a user actually uses the search system, the user often searches only with fragmented information such as region or name, rather than knowing all the conditions.

Therefore, there is a need for a destination search method that allows users to enter only as many conditions as they know and allow the user to find them again in the results, as well as freely modify the search conditions in the middle of searching.

The present invention is to compensate for the shortcomings of the conventional destination search method that the user can perform the search only if all the conditions necessary for the destination search described above can be performed.

In addition, even if the user does not completely know the search condition of the destination, the purpose is to induce the search can be performed within the known conditions.

In addition, there is another purpose to reduce the search condition selection step as you become familiar with the search method.

According to a preferred aspect of the present invention to achieve the above object, a condition selection step of selecting at least one condition classification from the multi-level condition classification of region, industry, name for the destination search without distinguishing the upper / lower classification;

It provides a destination search method of a navigation system comprising the step of performing a destination search according to the selected condition classification.

Preferably, after determining whether all the conditions required for the destination search is selected, if the condition selection is required, characterized in that it comprises a condition adding step of adding a condition.

Preferably, the method comprises a condition correction step of correcting the condition after determining whether there is a correction in the selected condition for the destination search.

Preferably, the local classification, industry classification, name in the conditional classification is characterized in that it can be searched by a single condition and can be selected together with other conditional classification.

Preferably, at least one or more of the subdivided classifications of the plurality of conditions selected from the condition classifications may be further selected.

Preferably, at least one or more of the subdivided classification of the plurality of conditions selected from the condition classification may be modified.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a destination search flowchart in accordance with the present invention.

Referring to FIG. 3, one of a name, a region, and an industry of a destination to be searched by a user is selected / entered in the destination search classification window of the navigation system according to the present invention (S300).

Then, it is determined whether all the conditions necessary for searching for a destination to be searched for by the user in the destination search classification window of the navigation are all selected and entered in the input unit 106 of the navigation (S302). In other words, it is possible to add a destination search condition.

If it is determined that the condition necessary for the destination search has not been completely input, at least one of a name, a region, and a business type is added and input again in step 300. After all necessary conditions have been selected / input from the user, it is determined whether there is no modification of the destination search condition (S304).

If it is determined in step 304 that there is no further modification of the destination search condition, the destination search is performed according to the selected condition by the user's command (S306).

However, if it is determined in step 304 that the destination search condition is to be corrected by the user, go back to step 300 and one or more of the selected name, region, and business type should be modified.

Step 304 may also be modified before step 302 and step 306 may be performed before step 302 or step 304.

FIG. 4 is a diagram illustrating a case in which a naming condition is selected and searched alone to find “Dongdaemun athletic field station” according to an embodiment of the present invention.

Referring to FIG. 4, even if the user's first, second, and third selection stages, local, middle, and small classification stages, and the fourth and fifth selection stages of industry, large and small classification stages are not input, If the keyword "Dongdaemun Stadium" is entered by the user, the names including the Dongdaemun Stadium may be derived, namely, the Dongdaemun Stadium Station and the Dongdaemun Stadium.

In other words, within each category of name, region, industry, etc., the name may be searched by the name itself, and may be selected together with other conditions.

5 is a case where a condition is selected using the local classification and industry classification instead of the name according to the present invention.

Referring to FIG. 5, "Seoul" is selected by the user as the first major selection step, "Seoul" is selected by the user, "Traffic" is selected by the fourth classification as the industry classification, and the name of the sixth selection step is not entered. .

As a result of the search, when a high-speed terminal, Seoul station, Jongno 3-ga station, Dongdaemun athletic field station, etc. related to traffic in Seoul are searched, the user can search for a destination Dongdaemun athletic field station.

That is, in the destination search method according to the present invention, the local large classification, which is the first selection step, may be searched by a single condition, and may be selected together with other conditions such as the local sub classification, the local sub classification, the name, and the industry.

In addition, the regional middle classification, which is the second selection stage, can be selected from among the lower subclasses after selecting the regional major classification, which is the first selection stage. have.

In addition, the regional sub-classification, which is the third selection stage, can be selected from among the sub-classifications after selecting the regional sub-classification, which is the first selection stage, and then the regional sub-classification, which is the second selection stage. Can also be selected with a transient.

That is, the user can select only the desired level without having to select the small category all the time.

6 is a partial flowchart of name selection among name, region, and industry type.

Referring to FIG. 6, names in each category may be searched by the name alone, and may be selected together with other conditions (S600).

A specific implementation is as mentioned in Figure 4, the input of the name is possible with a keyboard attached to the navigation system.

7 is a partial flowchart of selecting a region among names, regions, and industries.

Referring to FIG. 7, when an area selection classification is selected from the user, first, the area classification is selected (S700), and it is determined whether the selection is completed (S702), and when the selection is completed, the condition selection is completed. However, if the selection is not completed, the user selects the local middle classification again (S704), and determines whether the selection is completed (S706).

As a result of step 706, if the selection is completed, the condition selection is completed. If the selection is not completed, the local subclass selection is made again (S708) to complete the condition selection.

As described above, the local classification can be searched by a single condition and can be selected together with other conditions. In addition, regional subclasses can be selected from among subclasses after selecting a major category, can be searched by a single condition, and can be selected together with other conditions.
