BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation system for searching a driving route of a predetermined moving object including a vehicle, and guiding the moving body along a searched driving path. Particularly, the present invention relates to a navigation system in which partial map data must be updated in real time. The present invention relates to a driving route guidance method of a moving object of a navigation system for extracting a guide target point located in a driving route of a moving object so as to accurately guide the driving route of the moving object at the guide target point.

The navigation system is a navigation message transmitted by a plurality of GPS satellites belonging to a Global Positioning System (GPS), and a moving object detected by a plurality of sensors installed in a moving object such as a gyroscope and a speed sensor. Detects the current position of the moving object currently being driven by using the state detection signals, matches the detected current position with the map data, and displays it on the display unit, and also provides a predetermined destination from the current position of the moving object or the starting point of the moving object through the map data. The present invention provides a function of guiding the driving route so as to search the driving route up to and driving the moving object along the searched driving route.

When a moving object travels along the searched driving path, a predetermined guidance target point including a danger area, an intersection, an underground road, an overpass, an expressway entrance and exit road, etc., located in front of the moving body of the moving object is searched for, and the moving object is located. When the approaching target point is approached within a predetermined distance, the driving route of the moving object at the guide target point is guided by a voice signal or the like, and the moving object moves away from the driving route and travels on another road. If it is determined whether the path deviation is determined, the user is notified of the path deviation of the moving object to accurately move the moving object along the driving path.

In such a navigation system, in order to guide the driving of a moving object at a predetermined guide target point, all the guide target points located in the searched driving path are extracted when the search of the traveling path of the moving object is completed.

When the extraction of the guide target point is completed and the moving object travels, the distance between the moving object and the guide target point is detected, and when the guide target point is located within the set distance in front of the moving object, the driving at the guide target point is performed. Guided the route.

This conventional technique will be described in detail with reference to the drawings of FIG. 1.

1 is a signal flow diagram illustrating a conventional driving route guidance method. As shown in FIG. 100, when the user of the moving object inputs a starting point and a destination of the moving object to the navigation system through an input means or the like in step 100, and in step 102, the navigation system commands the search of the driving route. In 104, the driving data is searched for the moving object from the starting point to the destination by using the map data, and the searched driving path is displayed on the display unit so that the user can check.

In the next step 106, all the guide target points located on the searched driving path are extracted and stored, and when the moving object travels in step 108, the navigation message and the moving object received by the GPS receiver in step 110 The current position of the moving object is determined by using the driving state detection signal detected by the sensor unit installed in the sensor unit, and the displayed current position of the moving object is matched with the map data and displayed. The guide point located in front is detected and displayed on the display unit.

In the next step 112, the distance from the current position of the moving object to a predetermined guide target point located in front of the moving object of the moving object is calculated, and in step 114 whether the calculated distance is equal to or less than a preset threshold distance; To judge. As a result of the determination in step 114, when the distance from the current position of the moving object to the guide target point is calculated and is less than or equal to the threshold distance, the guide voice signal for guiding the moving direction of the moving object at the guide target point in step 116 is obtained. Create, print, and listen to the user.

In the next step 118, it is determined whether or not the moving object has arrived at the destination, and when the determination result is not reached, the flow returns to step 108 to detect the current position according to the moving of the moving object, It calculates the distance from the current position to the guidance target point to determine whether it is below the threshold distance, and repeats the operation of guiding the driving route with a voice signal when the distance from the current position of the moving object to the guidance target point is less than the threshold distance. When the moving object arrives at the destination in step 118, the guide operation of the traveling path of the moving object is terminated.

This conventional technology is provided with a very large storage means in the navigation system to search the driving route of the moving object using the map data stored in the storage means where all the map data is stored, and extract the guidance target point of the moving object There is a problem that can not be applied to the navigation system for guiding the driving route of the moving object while updating the map data in real time as enduring the driving route.

That is, the navigation system embedded in the mobile communication terminal cannot store all the map data due to the capacity limitation of the storage means, and only stores the partial map data of the predetermined area including the location of the current moving object. In this case, when the moving object travels in the partial map data of the predetermined area stored in the navigation system, the moving path of the moving object is searched using the partial map data of the predetermined area, and the moving object is searched along the searched driving path. The driving route can be guided to drive.

However, when the navigation system does not search the driving route of the moving object when the destination is located outside the area of the partial map data stored in the navigation system, the navigation system searches for the driving route of the moving object by communicating with an external map data providing center. And request, the center for providing the map data according to the request is to provide a search for the driving route of the moving object.

When the moving object leaves the area of the partial map data stored in the navigation system, the partial map data of the area located in front of the driving path of the moving object is requested to the map data providing center, and the map data is provided according to the request. The driving route of the moving object should be guided while updating the partial map data provided by the center in real time.

As described above, in guiding the driving route of the moving object while updating the partial map data in real time, the guide target point is not included in the partial map data updated in real time without the information about the guiding target point in the found driving route of the moving object. Contains information about.

Therefore, after the driving path of the moving object is searched, the information about all the guide target points located in the driving path cannot be extracted at once, and thus, there is a limit in accurately guiding the driving path of the moving object.

Therefore, an object of the present invention is to extract the guidance target point located in the driving route of the moving object from the updated partial map data when updating the partial map data in real time, so that the moving object of the moving system can be accurately guided. To provide a route guidance method of the.

Another object of the present invention is to determine the distance between the guide target points, and when the determined guide target points are less than a predetermined distance to distinguish the corresponding guide target points, the driving of the moving object according to each guide target point separated The present invention provides a driving route guidance method of a moving object of a navigation system that effectively guides a route.

The driving route guidance method of the moving object of the navigation system of the present invention having the above object, the control unit receives the starting point and the destination of the moving object through a command input unit and requests the driving route from the starting point to the destination to the map data providing center In response to determining whether the partial map data stored in the memory is updated or not, the partial map data received from the center for providing map data is updated and stored in the memory, and stored in the memory. Extracting the guide target point located on the traveling route, detecting the current position of the moving object when the moving object travels, and determining the distance between the guide target point located in front of the moving object from the detected current position of the moving object. Judging from the current position of the moving object It characterized in that it performs the operation guidance for the guidance target point when the distance between the target point is less than a preset threshold distance.

The starting point of the moving object and the current position of the moving object are positions determined by the control unit by a mixed navigation using a navigation message received by the GPS receiver and a driving state detection signal of the moving object detected by the sensor unit.

The determination of the update of the partial map data may include that the starting point of the moving object is not included in the partial map data, or the index information of the partial map data stored in the memory is different from the index information of the map data searched for the driving route, or It is characterized in that it is determined that the partial map data needs to be updated when the remaining distance for guiding the driving route of the moving object with the partial map data is less than the set distance.

After extracting the guide point, the guide points are divided into single path guide points, compound path guide points or three or more compound path guide points according to the extracted distances between the guide points. The guide operation may be performed by guiding a driving route according to the divided single route guidance target point, the composite route guidance target point, or triple or more complex route guidance target points.

The division of the guide target point is a plurality of guide target points from the destination to the starting point sequentially set as the current guide target point and the next guide target point, and calculates the distance between the current guide target point and the next guide target point set in advance It is determined whether it is less than or equal to the set threshold distance, and if it is not less than or equal to the threshold distance, the next guide target point is determined as a single path guide target point. If the current guide point is determined to be a single-path guide point, the current guide point and the next guide point are combined to determine the combined route guide point. As a result of the determination, the current guide target point is determined as the complex route guide target point. The combined that the current guidance target point, the next guidance target point on the guidance target point is determined by a composite route guidance target point, including the air if characterizes in determining the least complex route guidance target point of the three.

The guidance at the compound route guidance target point is guided by a voice signal simultaneously to the two guidance target points, and the guidance at the triple or more complex route guidance target points is three or more guidance target positions located in the front of the moving object. It is determined whether the first target location is located among the compound path guide locations, and if the first guide location is located as a result of the determination, the first guide location and the next guide location are located. Guides the distance and direction of travel, guides the next branch to be continued, and, if the target location is not the first location to be guided, to the number of guided locations remaining in front of the moving object among the three or more complex path guided locations. Accordingly, it is characterized in that to perform a single path guide, compound path guide or triple or more complex path guide.

Hereinafter, the driving route guidance method of the moving body of the navigation system of the present invention will be described in detail with reference to the accompanying drawings of FIGS. 2 to 5.

2 is a block diagram showing the configuration of a navigation system to which the driving route guidance method of the present invention is applied. As shown therein, the GPS receiver 210 receives the navigation message transmitted by the GPS satellite through the antenna 200, and communicates with an external map data providing center (not shown). An interface unit 220 for requesting the search of the driving route and the provision of the partial map data, and for receiving the driving route and the partial map data of the moving object provided by the map data providing center according to the request. By installing a gyroscope and a speed sensor, the sensor unit 230 detects a moving state such as a moving direction and a moving speed of the moving object, a memory 240 for storing partial map data, and the interface unit 220. Ask the outside center for providing the map data to search for the driving route of the moving object and to provide the partial map data. Receives a route route and partial map data and stores the data in the memory 240, and uses a navigation message received by the GPS receiver 210 and a moving state detection signal of a moving object detected by the sensor unit 230. A control unit 250 for controlling an operation of guiding a driving route of the moving object while determining a current position of the moving object and matching and displaying the determined current position of the moving object with the partial map data stored in the memory 240; A display unit 260 for displaying a current position of the map and the moving object and the driving path of the moving object under control of the control unit; a command input unit 270 for inputting an operation command according to a user's operation to the control unit 250; The guide voice generator 280 generates a guide voice signal under the control of the controller 250 and outputs the guide voice signal to the speaker 290.

In the driving route guidance method of the present invention applied to the navigation system having such a configuration, in step 300, a user of the moving object manipulates the command input unit 270 to input a starting point and a destination of the moving object, and in step 302 the driving route. When a search request command is input, the controller 250 performs data communication with the server for providing map data through the interface unit 220 and the antenna 200 in step 304 to start and destination of the input moving object. Sends a request for navigation of the driving route.

In the next step 306, the controller 250 receives the driving path of the moving object searched by the server for providing map data according to the request through the antenna 200 and the interface unit 220, and stores the driving path in the memory 240, In step 308, it is determined whether the partial map data currently stored in the memory 240 should be updated. That is, the controller 250 determines whether the starting point of the moving object is included in the partial map data stored in the memory 240 and determines that the partial map data should be updated when the starting point of the moving object is not included. In addition, when the searched driving route is received, index information of the partial map data used to search the driving route is provided together with the index information and the memory 240 of the partial map data used to search the driving route. By comparing the index information of the partial map data stored in), it is determined that the partial map data should be updated when the index information is different.

When the partial map data needs to be updated as a result of the determination of step 308, the controller 250 performs data communication with the server for providing map data through the interface unit 220 and the antenna 200 in step 310. The partial map data to be updated is requested, and according to the request, the partial map data provided by the map data providing server is received and updated and stored in the memory 240.

In the next step 312, the control unit 250 extracts the guide target points located in the driving route of the moving object using the partial map data stored in the memory 240, and in step 314 for the extracted guide target points The single path guide target point, the double compound path guide target point and the triple or more compound path guide target point is divided into the memory 240 to be stored.

Here, as shown in FIG. 4, the control unit 250 sets the destination of the moving object to the current guide point G1 as shown in FIG. 4, and in step 402, the direction of the departure point from the destination. Then, the guide point closest to the destination is detected and set as the next guide point G2.

In the next step 404, the control unit 250 determines whether the next guide point G2 set as described above is the starting point of the moving object, and if it is not the starting point, from the current guide point G1 in step 406. Next, the distance between the guide points G2 is calculated to determine whether the calculated distance is equal to or less than the predetermined threshold distance in step 408. That is, it is determined whether or not each guide target point is within a distance that can sufficiently guide the driving route with a voice signal.

If it is determined that the step 408 is not less than or equal to a preset threshold distance, the controller 250 determines the next guide point G2 as the single-path guide point R1 in step 410.

When the determination result of the step 408 is less than or equal to a preset threshold distance, the controller 250 determines whether the current guide point G1 is determined as the single-path guide point R1 in step 412. To judge.

If the current guide target point G1 is determined as the single-path guide target point R1 as a result of the determination of step 412, the current guide target point G1 and the next guide target point G2 in step 414. In addition, it is determined that the combined route guidance target point R2 is changed to the sum, and as a result of the determination of step 412, the current guidance target point G1 is not determined as the single route guidance target point R1, and the composite route guidance target point R1 is determined. (R2) or when the triple or more complex route guidance target point (R3) is determined, the next guide route (G2) to the complex route guidance target point (R2) or triple or more complex route guidance target points (R3). ) Is set to three or more complex route guidance target points (R3).

In this way, after determining the single path guided point R1, the compound path guided point R2, or the three or more compound path guided points R3 for the next guided point G2, the control unit 250 determines In step 418, the next guide point G2 is set as the current guide point G1, and the flow returns to step 402 to detect the next guide point G2, and then detects the next guide point ( The operation of determining the next guide point (G2) as a single route guide point (R1), compound route guide point (R2), or triple or more compound route guide points (R3) until G2) becomes the starting point. In step 404, if the next guide point G2 is the starting point, the classification operation of the guide point is terminated.

In this way, the moving object travels in step 316 after all the guide points are divided into single path guide points R1, compound path guide points R2, or triple or more compound path guide points R3. In this case, the control unit 250 determines the current position of the moving object using a mixed navigation method using the navigation message received by the GPS receiver 210 and the driving state detection signal of the moving object detected by the sensor unit 220 in step 318. After matching the determined current position of the moving object to the partial map data stored in the memory 240 and displayed on the display unit 360 so that the user can check the current position of the moving object.

In a next step 320, the control unit 250 detects the guide target point located at the position closest to the traveling front of the moving object from the determined current position of the moving object to calculate the distance from the current position of the moving object to the guide target point, When the calculated distance is less than or equal to the predetermined threshold distance in step 322, the driving path guidance operation of the moving object to the guide target point is performed in step 324.

As shown in FIG. 5, the driving route guidance of the moving object in the step 324 may include the single-path guidance target point R1, the compound path guidance target point R2, or triple, in step 500. It is determined whether or not the composite route guide target point is R3.

As a result of the determination of step 500, when the guide target point is a single path guide target point R1, the controller 250 controls the voice signal generator 280 in step 502 to control the single path guide target point ( Generating a guide voice signal for guiding R1) For example, a single-path guide voice signal "turn left at about 100m ahead" is generated and output to the speaker 290.

When the guide point is the compound route guide point R2, the control unit 250 controls the voice signal generator 280 in step 504 to determine the compound route guide point. Generating a guide voice signal for guiding (R2) For example, a compound path guide voice signal of "turn left at about 100m ahead and turn right at about 10m forward" is generated and output to the speaker 290.

In addition, when the guidance target point is a triple or more complex route guidance target point R3 as a result of the determination of step 500, the control unit 250 determines in step 506 the triple or more complex route guidance target point R3. It is determined whether or not the first target location to be positioned, and in the case of the first target location to be guided, in step 508, by controlling the voice signal generator 280, the triple or more compound path guide destination points (R3). To generate a guide voice signal for guiding the speaker, for example, "Turn left at about 100m ahead and turn right at about 10m forward. Then, the branch will continue." 290).

In addition, when the determination result of the step 506 is not the guide target position located at the beginning of the triple or more complex route guide target point R3, the control unit 250 guides the vehicle located at the front of the moving body in step 510. According to the number of remaining guide target points from the target point, single path guidance, compound route guidance or triple or more complex route guidance operations are selectively performed. For example, when the number of remaining guide points is one, the controller 250 controls the voice signal generator 280 to generate a single-path guide voice signal "turn left at about 5m ahead" and generate The guide voice signal is output to the speaker 290, and when the number of remaining guide points is 2, a compound path guide voice signal is generated by "turn left at about 5m ahead and turn right at about 10m forward." 290), and if there are more than 3 remaining guides, turn left at about 5m ahead and turn right at about 10m forward. The next quarter will continue. It generates and outputs to the speaker 290.

As a result of the determination in step 322, when the distance between the current target position of the moving object and the guide target point is not less than or equal to the threshold distance, the controller 250 determines whether the partial map data is updated in step 326. For example, the controller 250 may use the partial map data currently stored in the memory 240 so that the remaining distance capable of guiding the driving route of the moving object is less than the set distance, for example, the partial map data from the server for providing map data. When the moving object is less than the distance that the moving object can travel during the time that can be provided and updated, the control unit 250 performs data communication with the server for providing map data through the interface unit 220 and the antenna 200 in step 328. Request partial map data to be updated and performed, that is, request partial map data including an area in front of the moving object of the moving object, and receive partial map data provided by the server for providing map data according to the request to the memory 240. Save the update.

When the update of the partial map data is completed, the control unit 250 returns to step 312 and extracts the guide target point located on the driving route of the moving object from the updated partial map data, and guides the extracted guide target point to a single path. When the guide target point is located within the set distance of the front of the moving object after dividing it into the target point (R1), the combined route guided point (R2) or the triple or more combined route guided points (R3), the corresponding guided point Repeat the operation of guiding the driving route for.

If the determination result of step 326 does not require updating of the partial map data, the controller 250 determines whether or not the moving object has arrived at the destination in step 330. In the case of returning to the step 316, when the guide target point is located within the set distance of the front of the moving object, the driving route for the guide target point is guided, and the partial map data is required when the update of the partial map data is necessary. Repeat the operation of updating, and when the moving object arrives at the destination, the driving path guidance operation of the moving object is terminated.

On the other hand, while the present invention has been shown and described with respect to specific preferred embodiments, various modifications and changes of the present invention without departing from the spirit or field of the invention provided by the claims below It can be easily understood by those skilled in the art.

As described above, the present invention can accurately guide the driving route of the moving object by extracting the guide target point located in the driving route of the moving object whenever the partial map data is updated in the navigation system that needs to update the partial map data in real time. Of course, according to the distance between the guided points, the guided points are divided into single path guided points, double compound path guided points, and triple or more compound path guided points, and the distance between guided points is continuous. Even if it is short, it can accurately guide the driving route of the moving object.
