NAVIGATION APPARATUS AND METHOD FOR GUIDING ROUTE IN THE NAVIGATION APPARATUS}

The present invention relates to a navigation device, and more particularly, a method of guiding a driving route of a point of interest (POI) in a navigation service that provides map data including location information of a moving object such as a vehicle. And a navigation device capable of performing this method.

As is well known, the navigation device displays the current location of a moving object such as a vehicle on a map displayed on a display screen using information received from a GPS (Global Positioning System). Such a navigation device is currently mounted on various moving objects such as ships, aircrafts, vehicles, etc., and is widely used to determine the current position and moving speed of moving objects or to determine a moving path.

BACKGROUND ART A vehicle navigation apparatus applied to a vehicle traveling on a road provides various information, such as road congestion, along with a current driving road and a location and a driving path of a road, visually or acoustically. In addition, the vehicle navigation device displays various information necessary for driving such as displaying the driving direction of the vehicle, the distance to the destination, the current moving speed of the vehicle, the route set by the driver before driving, the optimum route to the destination, and the like. Provide the driver.

Such a navigation device for a vehicle receives a radio wave indicating latitude, longitude, altitude, etc. from a plurality of satellites belonging to a GPS, calculates the current location of the vehicle, and visually displays map data including the current location. Receives satellite radio waves from GPS satellites, calculates radio wave reception distance from satellites, detects the current location and vehicle speed of the vehicle, detects map data for the pre-stored relevant area, and then maps the current location detected through the display. To display with the data.

In addition, the navigation device has point of interest information based on map data. Points of interest are data that represent key facilities, stations, airports, terminals, hotels, etc., in predetermined coordinates on a map. Accordingly, the navigation device may provide route data including road information and a point of interest based on map data existing on the route in consideration of the position of the driving vehicle. The driving route information from the current location to the point of interest may be guided. Here, the driving route information includes distance and estimated time information from the current position to the point of interest, rotation position and direction information such as an intersection, driving lane information, road surface information, prescribed speed information, and the like.

When rotating in a rotational direction different from the one rotational direction information, it is determined that the driving path has deviated, and after re-searching the driving path, the changed rotational position and the rotational direction information are guided.

As shown in the drawing, the navigation device 110 includes a first input unit 120, a second input unit 130, a location information generator 140, a data storage unit 150, a controller 160, and an image processor 170. , An image output unit 175, a voice processor 180, an audio output unit 185, and the like, and the data storage unit 150 includes an application program storage unit 151, a map data storage unit 153, and the like. It is configured by.

The first input unit 120 is a means for inputting various commands such as destination setting and route guidance to the navigation device 110, and may be implemented as an operation panel of the navigation device 110 or a general remote controller. The point of interest for receiving the guidance of the driving route may be input or searched through the first input unit 120.

The second input unit 130 may be implemented as a touch panel which can be integrally installed on the output screen of the image output unit 175, and provides the screen coordinate values according to the touch input to the controller 160. The second input unit 130 may input a point of interest for receiving a guidance of a driving route or select a search like the first input unit 120 through the screen interface.

The location information generating unit 140 generates a location coordinate value by receiving radio waves from a plurality of satellites, ie, GPS satellites, belonging to the GPS through an antenna, and may be implemented by a general GPS receiver.

The application program storage unit 151 stores operating programs and various application programs necessary for operating the system, and the map data storage unit 153 compresses map data compressed at a predetermined scale ratio, pre-registered point of interest information, and the like. A database containing additional information data is stored.

The data storage unit 150 including the application program storage unit 151 and the map data storage unit 153 may be implemented using a hard disk drive, a flash memory, a compact flash memory, or the like.

The image processor 170 outputs screen display data to be displayed on the electronic map generated by converting the map data under the control of the controller 160 and including the position information based on the position coordinate value.

The image output unit 175 outputs the electronic map according to the screen display data of the image processor 170. The image output unit 175 may be implemented as an LCD (Liquid Crystal Display).

The voice processor 180 outputs voice data corresponding to the vehicle driving information generated by the controller 160.

The voice output unit 185 outputs the vehicle driving information so that the user can be audibly checked according to the voice data of the voice processor 180. The voice output unit 185 may be implemented as a speaker.

The controller 160 controls the overall operation of the navigation device 110. For example, the controller 160 calculates the current position information of the vehicle based on the position coordinate value transmitted from the position information generation unit 140, and the vehicle progress direction and the rotation position such as left turn and right turn in time direction units. Generate vehicle driving information such as distance.

The controller 160 controls the display data of the surrounding area to be visually displayed through the image output unit 175 based on the calculated vehicle location information and reads the map data from the map data storage unit 153. The information is controlled to be output acoustically through the voice output unit 185.

In addition, when a command for requesting guidance of a driving route to a point of interest is input through the first input unit 120 or the second input unit 130, the controller 160 stores an operating program and an application stored in the application storage unit 151. The program is driven to control the processing of the electronic map by the image processor 170.

In particular, when the vehicle 160 deviates from the driving route guided by the vehicle while guiding the driving route to the point of interest through the image output unit 175, the new driving route information generated by re-searching the driving route is generated. It is output through the image output unit 175 and the audio output unit 185. At this time, the rotation risk value of the rotation position close to the current position of the vehicle among the rotation positions changed by the re-search of the driving route is calculated. If the calculated rotation risk value satisfies the driving route changing condition, the corresponding rotation route is changed. Generates a new driving route information. In addition, the setting of the driving route information based on the result of calculating the rotation risk value and the driving route changing condition for the adjacent turning positions can be applied not only to re-searching the driving route but also when searching for the driving route for the first time. have.

In addition, when the vehicle approaches the front rotation position while guiding the driving route, even when the vehicle does not leave the driving route, when the current driving state information of the vehicle satisfies the driving route changing condition, the driving route is re-searched and moved forward. The new driving route information generated by changing the rotation position is output through the image output unit 175 and the audio output unit 185.

In the navigation device 110 configured as described above, in the case of not supporting the audio output, the navigation device 110 may be designed by excluding the audio processing unit 180 and the audio output unit 185, and the image output unit 175 and the audio output unit ( When the 185 is implemented as a separate peripheral device, the image output unit 175 and the audio output unit 185 may also be excluded.

A process of guiding a driving route to a point of interest in the navigation device according to the embodiment of the present invention configured as described above will be described with reference to FIGS. 2, 3A, and 3B. Through the description of the service process, the functions of the individual components constituting the navigation device 110 may be more specifically understood.

First, when a navigation menu is selected through the first input unit 120 or the second input unit 130 of the navigation device 110, the controller 160 enters the navigation mode (S203) and is stored in the application program storage unit 151. The operating program and the application program are driven (S205).

In such a navigation mode, the location information generator 140 receives a radio wave through an antenna, generates a position coordinate value of the moving object, and provides the generated location coordinate value to the controller 160 (S207). The controller 160 maps the data storage unit 153. Extract map data preloaded on the

The controller 160 generates the electronic map by including the position information of the moving object based on the position coordinate value in the map data, and the image processor 170 generates the electronic map based on the map data. The image is processed to be included in the image and output through the image output unit 175 (S209).

On the other hand, when the user searches for a point of interest, the user inputs a point of interest name corresponding to a destination to go through the first input unit 120 or the second input unit 130. In this case, when the name of the point of interest corresponding to the destination to be precisely registered is not registered in the navigation device 110 or when the name of the point of interest is not known, another name of the point of interest existing in the vicinity may be input (S211).

Then, the controller 160 extracts the point-of-interest information corresponding to the point-of-interest name input through the first input unit 120 or the second input unit 130 from the point of interest information previously registered in the map data storage unit 153. The image processor 170 is provided to the image processor 170, and the image processor 170 processes the image of the point of interest information and outputs the image through the image output unit 175 (S213).

Here, the point of interest name input through the first input unit 120 or the second input unit 130 and the point of interest information previously registered in the map data storage unit 153 may be matched one-to-one, but in most cases, the point of interest is registered. A plurality of points of interest information is retrieved from the points of interest information. For example, when searching for a business name, a plurality of points of interest information is searched because there is a high probability that a plurality of stores having the same business name exist in the whole country. In addition, when a specific industry or a theme is entered as a search term using a group search function such as an industry search or a theme search, a plurality of points of interest information registered as a corresponding industry or theme are searched.

As such, if any point of interest information is selected through the image output unit 175 through the first input unit 120 or the second input unit 130, the controller 160 maps the map data. The driving route from the current location to the point of interest is searched and generated based on the map data stored in the storage unit 153, and the generated driving route is included in the map data to provide an electronic map. That is, the image processor 170 outputs the electronic map processed by the image to include the location information and the driving route through the image output unit 175, and the audio processor 180 controls the driving route information under the control of the controller 160. The corresponding voice information is output through the voice output unit 185 (S217).

For example, as shown in FIG. 3A, the driving route information 313 may be provided from the current position 1 of the vehicle through the first intersection 311 and the second intersection 312 to the point of interest 3. .

In this case, the controller 160 calculates the current position information of the vehicle based on the position coordinate value transmitted from the position information generator 140 even while guiding the driving route to the point of interest through the image output unit 175, The vehicle driving information such as a left direction and a right direction in the time direction unit, such as a vehicle traveling direction and a distance to the rotation position is generated.

In this case, when the vehicle deviates from the driving route guided by the vehicle, the controller 160 outputs the new driving route information generated by re-searching the driving route through the image output unit 175 and the audio output unit 185. .

Further, when the vehicle approaches the rotational position while guiding the driving route (S219), even when the vehicle does not leave the driving route, when the current driving state information of the vehicle satisfies the driving route changing condition (S221 to S223). The new driving route information generated by changing the rotational position by re-searching the driving route is output through the image output unit 175 and the audio output unit 185.

For example, as shown in FIG. 3B, the driving route information from the current position 1 of the vehicle through the first intersection 311, the third intersection 314, and the fourth intersection 315 to the point of interest 3 ( 316).

In this case, when the control unit 160 determines that the vehicle is close to the forward rotation position, it is determined that the risk of an accident is high by excessively attempting to turn by changing the lane of the lane at the position where the forward rotation position is not left. It is to. Accordingly, the controller 160 may compare the distance value to the forward rotation position with the preset reference distance value and determine whether the vehicle is close to the forward rotation position according to the comparison result. For example, when the distance value to the front rotation position is smaller than the preset reference distance value, it is determined that the vehicle is close to the front rotation position. Here, the reference distance value may be set to different values according to the type of the driving road. For example, the reference distance value of the highway may be set longer than that of the general road.

In addition, as shown in the embodiment of FIG. 2, the controller 160 calculates a rotation risk value to determine whether the current driving state information of the vehicle satisfies the driving path change condition, and calculates the rotation risk value and the calculated rotation risk value. The reference risk value may be compared to determine whether the vehicle satisfies the driving route change condition based on the comparison result. For example, when the calculated rotation risk value is higher than the preset reference risk value, it is determined that the vehicle satisfies the driving route change condition. Here, the rotation risk value may use a calculation formula including a current speed of the vehicle, a time required for searching the driving route, and a reaction time of the user after providing the driving route.

Finally, the image processor 170 outputs the electronic map processed by the image to include the location information and the new driving route information through the image output unit 175 to guide the driving route again, and the audio processor 180 controls the controller ( The voice information corresponding to the new driving route information is output through the voice output unit 185 under the control of 160 (S225).

Hereinafter, a process of guiding a driving route to a point of interest in a navigation device according to another embodiment of the present invention will be described with reference to FIGS. 1, 3A, 3B, and 4. Here, since S403 to S417 of FIG. 4 corresponds to S203 to S217 of FIG. 2, a description thereof will be omitted below.

The controller 160 calculates the current position information of the vehicle based on the position coordinate value transmitted from the position information generator 140 even while guiding the driving route to the point of interest through the image output unit 175, and the time direction. The vehicle driving information such as the vehicle traveling direction such as the left turn and the right turn of the unit and the distance to the rotation position are generated.

When determining that the vehicle deviates from the driving route guided by the vehicle during the driving route guidance, the controller 160 re-searches the driving route to guide the new driving route (S421).

In addition, the controller 160 calculates a rotation risk value for the proximity rotation position in the re-searched driving path. This is to determine the case of high risk of accident by attempting to turn excessively by changing the lane of the lane in the position that does not leave the forward rotation position. Therefore, the controller 160 compares the distance value to the forward rotation position with the preset reference distance value and selects the proximity rotation position according to the comparison result. In this case, a single proximity rotation position may be selected, and two or more proximity rotation positions may be selected. For example, when the distance value to the predetermined rotation position is smaller than the preset reference distance value, the rotation position is selected as the proximity rotation position. Here, the reference distance value may be set to different values according to the type of the driving road. For example, the reference distance value of the highway may be set longer than that of the general road. Then, the rotation risk value is calculated for the selected near rotation position. Here, the rotation risk value may use a calculation formula including the current speed of the vehicle, the time required to search the driving route, and the reaction time of the user after providing the driving route (S423).

Next, the controller 160 compares the calculated rotation risk value with a preset reference risk value and determines whether the rotation position satisfies the driving route change condition according to the comparison result. For example, when the calculated rotation risk value is higher than the preset reference risk value, it is determined that the corresponding rotation position satisfies the driving route change condition (S425).

In addition, the controller 160 generates a driving route maintaining the rotation path or a driving route changing the rotation path according to the determination result of step S425. For example, the driving route from the current position 1 of the vehicle to the point of interest 3 passing through the first intersection 311 and the second intersection 312 as shown in FIG. 3A as a result of the driving route re-search in step S421. In the case where the information 313 is generated, when the proximity turning position corresponding to the first intersection 311 does not satisfy the driving route changing condition, that is, when the rotation risk value is not high, the driving route information 313 of FIG. 3A. It is selected as is (S429). However, when the proximity turning position corresponding to the first intersection 311 satisfies the driving route changing condition, that is, when the rotation risk value is high, as shown in FIG. 3B, the first intersection at the current position 1 of the vehicle ( 311), the driving route information 316 to the point of interest 3 passing through the third intersection 314 and the fourth intersection 315 is changed and selected (S427).

Finally, the image processor 170 outputs the electronic map processed by the image to include the location information and the new driving route information through the image output unit 175 to guide the driving route again, and the audio processor 180 controls the controller ( The voice information corresponding to the new driving route information is output through the voice output unit 185 under the control of 160 (S225).

Meanwhile, in the above-described embodiment, the driving route information is set based on the calculation result of the rotation risk value for the adjacent rotational position and the driving route change condition when the navigation route is searched again. This is only an example of the case, and the same can be applied to not only re-navigating the driving route but also to searching the driving route for the first time.
