Description

Apparatus and method for move path search and guide information display in navigation device}

The present invention relates to a navigation route search and guidance information display apparatus and method in a navigation terminal. For example, the present invention relates to a navigation route to a specific destination desired by a user and to display guidance information on the found navigation route. The present invention relates to a navigation route search and guidance information display apparatus and method in a navigation terminal.

In general, various types of navigation terminals such as telematics terminals are widely used and commercialized. For example, in a navigation terminal mounted on a vehicle and searching for and displaying a moving path to a specific destination desired by a user, The current vehicle position is detected by using a GPS signal received through a satellite.

In addition, the navigation terminal reads out a map image stored and managed in the form of a database in storage in the device, and displays a traffic map image of the corresponding point along with the current vehicle position. For example, if the user designates any one specific destination, he or she will search for a travel route from the current vehicle location to the specific destination.

In addition, the searched moving path is displayed through a display screen such as an LCD (LCD). For example, in the navigation terminal, in order to guide the moving path to the specific destination more efficiently, the moving path After generating guide information for guiding the main points of the image, the guide information is displayed together with a map image of the moving route as a summary list that can be selected by the user.

Accordingly, the user can easily check the moving route to the specific destination desired by the user and the guide information for guiding the main points on the moving route in a summary list, so that the user can move to the specific destination more quickly and easily. .

Meanwhile, in the case of a general navigation terminal, for example, a navigation terminal used in a country or region with a relatively small land area such as Korea, Taiwan, Hong Kong, etc., as described above, the navigation path to a specific destination is searched and the movement is also performed. After generating all the guide information of the route, the first display method of simultaneously displaying the map image of the searched movement route and the generated guide information at the same time is used. In this case, the user waits. Discomfort does not occur largely because the time to do is relatively short.

On the other hand, in the case of a navigation terminal used in a country or region with a large land area such as North America, China, and Europe, a navigation route to a specific destination is searched, and all the guidance information on the movement route is generated. Subsequently, when the first display method of simultaneously displaying the map image of the searched moving path and the generated guide information at the same time is used, the user may experience a long waiting time, thereby causing inconvenience in use. do.

Accordingly, in the case of a navigation terminal used in a country or region with a large land area as described above, the navigation terminal searches for a movement route to a specific destination, first generates only some guide information on the movement route, and then searches for the navigation terminal. By using the map image of the moving route and the second display method of displaying only the firstly generated partial guide information, the waiting time for the user can be shortened.

However, when the second display method is used in a navigation terminal used in a country or region with a relatively small land area, a map image of a movement route and guide information corresponding to a part of the movement route are displayed, and then a predetermined time is displayed. After the elapsed time, the guide image corresponding to the remaining moving path is displayed again. Thus, although the user waiting time is short, there is a problem of performing an inefficient display operation of displaying the guide information unnecessarily sequentially.

Accordingly, the present invention has been created to solve the above problems, and searches for a travel route to a specific destination, wherein the searched travel route is a preset threshold value, for example, set by a user. After determining whether a limit value such as a maximum distance or the total number of links is satisfied, all the guide information is generated or only some of the guide information is generated first, and then the search is performed. It is an object of the present invention to provide an apparatus and method for searching and guiding a moving route of a navigation terminal for enabling efficient display operation and shortening user waiting time by displaying the same movement route.

According to an aspect of the present invention, there is provided a moving route search and guide information display method of a navigation terminal, the method including: searching for a movement route to a specific destination and generating guide information on the movement route; And determining whether the searched moving path satisfies a preset limit value, and selectively generating and displaying all guide information or part of the guide information on the moving path. ,

In addition, in the second step, if the searched moving path satisfies a preset limit value, after generating the entire guide information for the moving path, the searched moving path is set in advance. If the value is not satisfied, the guide information is generated after displaying some guide information on the movement route.

The limit value is one or more of the maximum distance of the movement path or the total number of links in the movement path, and is variably set by the user, and the guidance information is a summary list for guiding the movement paths. It is characterized by being displayed sequentially by selection,

In addition, the part of the guide information is displayed as a summary list for guiding only a part of the moving path corresponding to the limit value, and in the second step, the searched moving path does not satisfy the preset limit value. If not, after generating some guide information for the movement route and displaying it, the remaining guidance information for the movement route is continuously generated.

In addition, the navigation path search and guidance information display apparatus in the navigation terminal according to the present invention, the navigation terminal to search for the movement path to a specific destination, and to generate and display the guide information for the movement path, And a control means for controlling whether the searched moving path satisfies a preset limit value, and selectively generating and displaying the entire guide information or part of the guide information on the moving path. Characterized in that,

In addition, the control means, if the searched movement path satisfies a preset limit value, generates and displays the entire guide information for the movement path, and the searched movement path is a limitation set in advance If the value is not satisfied, it is characterized in that the control to generate and display some of the guide information for the movement path,

The limit value is one or more of the maximum distance of the movement path or the total number of links in the movement path, and is variably set by the user, and the guidance information is a summary list for guiding the movement paths. It is characterized by being displayed sequentially by selection,

The partial guide information is displayed as a summary list for guiding only a part of the moving route corresponding to the limit value, and the control means indicates that the searched moving path does not satisfy the preset limit value. After generating some of the guide information on the moving path and displaying the generated information, the remaining guide information on the moving path is continuously generated.

According to an apparatus and method for searching and guiding information on a navigation route of a navigation terminal according to the present invention, if a navigation route to a specific destination is searched, and the searched navigation route satisfies a preset threshold value, After generating and displaying all guide information on the movement route, the display operation can be efficiently performed at one time. If the found movement route does not satisfy a preset limit value, the movement route By generating and displaying some guide information for the first, it is possible to shorten the waiting time for the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a mobile route search and guide information table market value and method of a navigation terminal according to the present invention will be described in detail with reference to the accompanying drawings.

First, the movement route search and guidance information display apparatus according to the present invention may be applied to various types of navigation terminals such as a telematics terminal as shown in FIG. 1, and the speaker includes a speaker. And a display module 10 including a LCD and a navigation module in which a traffic map image, a node, and link information are stored and managed in a database form. 11) is configured to include.

In addition, the navigation terminal includes a CPU (CPU) 12, a central processing unit, a GPS module 13 for receiving a GPS signal and detecting a current position, and as shown in FIG. A CDMA module 14 for wirelessly communicating with various types of servers 300 ₁ to 300 _k operating in a telematics center through a mobile communication network (eg, CDMA) 200 may be included. have.

Meanwhile, in the CPI 12, when a user selects and inputs a specific destination, the GPS module 13 is operated to detect the current position, and the navigation module 11 is operated. Then, the moving path from the detected current position to the specific destination is searched.

In addition, the CPI 12 operates and controls the navigation module to generate guide information for guiding a main point of the movement route, wherein the found movement route has a preset threshold value. Value).

For example, in order to limit the operation of generating the guide information, the user may compare the maximum distance arbitrarily set with the total distance of the searched movement path, or the user may restrict the operation of generating the guide information. In order to achieve this, the total number of links arbitrarily set and the total number of links of the searched moving path are compared, and the link is defined as a connection road between nodes such as an intersection. Can be.

In the CPI 12, when the searched moving path satisfies a preset limit value by the comparison operation as described above, after generating all the guide information on the moving path, the display module ( 10) to control the operation, and simultaneously displays the movement route and the entire guide information.

On the other hand, if the searched moving path does not satisfy a preset limit value, only part of the guide information for the moving path is first generated, and then the operation of the display module 10 is performed to control the moving path and a part of the moving path. Only the guide information of the screen is quickly displayed, which will be described in detail below.

FIG. 2 is a flowchart illustrating an embodiment of a method for searching a moving route and displaying guide information in a navigation terminal according to the present invention. For example, in the CPI 12, a user selects and inputs an arbitrary specific destination. If so, the navigation module 11 is operated to search for a movement path from a current position to a specific destination (S10).

In addition, in the CPI 12, the navigation module 11 may be operated to perform a series of guide information generation operations for generating guide information on a main point existing on a moving path to the specific destination. In step S11, for example, when the search path to the specific destination is completed (S12), the searched travel path is compared with a preset limit value (S13).

As a result of the comparison, it is determined whether the searched moving path satisfies the limit value (S14). For example, a limit value arbitrarily set by the user to limit the guide information generation operation is determined. When the maximum travel distance is 50 km and the total travel distance of the searched travel path is 30.9 km, as shown in FIG. 3, in the CPI 12, the searched travel path is previously determined. It is determined that the set limit is satisfied.

In addition, the CPI 12 generates all the guide information on the searched travel path (S15), and then controls the display module 10 to operate the searched travel path and the corresponding information. Since the entire navigation information is displayed at the same time, since the searched movement path corresponds to a relatively short distance, it does not take much time to generate all the entire guidance information corresponding thereto, so that the user does not have to wait for a long time. do.

On the other hand, the guide information is displayed as a summary list indicating major points on the movement route, for example, as shown in FIG. 3, and the user is shown at any one point, for example, as shown in FIG. 4. When selecting a point called the Gyeongbu Expressway, the CPI 12 operates and controls the navigation module 11 to search for and display a map image of the corresponding point (Turn-By-). Turn) to perform the operation (S16).

On the other hand, the limit value arbitrarily set by the user to limit the guide information generation operation is the maximum movement distance '50 km 'and the total movement distance of the searched movement path is 380.1 km, as shown in FIG. 5. ', The CPI 12 determines that the searched moving path does not satisfy a preset limit value.

In addition, in the CPI 12, when all the guide information of the searched movement path is generated, it takes a long time, so that only the guidance information corresponding to a part of the movement path is preferentially generated. S17), for example, only some of the guide information corresponding to '50 km 'set as the limit value is generated.

In addition, the display module 10 is operatively controlled to display only the searched travel path and guide information corresponding to a portion thereof first (S16), which is a relatively long distance. In this case, since it takes a long time to generate all of the entire guide information corresponding thereto, only some guide information is displayed first so that the user does not wait for a long time.

Meanwhile, in the CPI 12, the navigation module 11 is operated to continuously generate guide information corresponding to the remaining part of the movement path (S19), and as shown in FIG. 6, the movement is performed. The guide information corresponding to the whole of the route is displayed again, and the guide information is displayed as a summary list indicating the main points on the moving route, as described above.

In the CPI 12, when a user selects an arbitrary point, a series of turn-by-turns for controlling and navigating the navigation module 11 to search for and display a map image of the corresponding point are performed. -Turn) to perform the operation (S20), if the searched moving path satisfies a preset limit value, after generating all the guide information for the moving path, the display operation can be efficiently performed at once. If the searched moving path does not satisfy the preset limit value, some guide information about the moving path is first generated and displayed, thereby shortening a user's waiting time. do.

The limit value may be arbitrarily set by the user and may be changed to various limit conditions such as the total number of links on the travel path, in addition to the maximum travel distance.
