Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device for drawing a mark pattern of a service mark on a map.

[0002]

2. Description of the Related Art In the case of visiting a land for the first time by car, it is necessary to examine a sufficient travel route in advance by a road map or the like in order to reach a destination without hesitation. In this examination of the driving route, it is of course necessary to select the driving route first, but in order to drive the selected route without fail, there are landmarks such as intersections and features that turn right and left on the driving route, It is necessary to remember road information such as mileage up to. However, if the road network becomes complicated, you may forget the name of the intersection to turn or the feature that serves as a mark on the route you are going to travel for the first time, or it may not be easy to check while traveling.
If you overlook the name of a crossing to turn or a feature that serves as a landmark and lose your current position, you may not be able to smoothly follow the flow of cars and you may get stuck on the way.

The navigation device provides route guidance so that a user can visit a destination for the first time without worrying about the above, and various types of navigation devices have been proposed in recent years. Among them are those that set the route to the destination and display the set route on the display and the remaining distance, name, right turn left etc. regarding the intersection that should turn so that you can definitely drive on that route. Information is provided, and teaching of a characteristic object is performed so that a route during traveling can be confirmed, and further, not only display but also voice guidance is provided.

In such a navigation device, it is first necessary to set a route. To set the route, it is necessary to enter the departure point and the destination,
When the departure place and the destination are determined by this input, a route search process is performed from the road information data around the departure place and the destination and between them, and an optimum route is set from a plurality of routes. In addition, in the method already proposed by the applicant, rather than setting a specific route from a starting point to a destination, a traveling road or a traveling direction to a destination at a specific point such as each intersection is set. There is also. In this case, traveling information such as traveling distance, steering angle, passing intersection, etc. is collected to recognize the current position, and information on the traveling road and traveling direction set at the current position is provided to guide the route. Is going.

As described above, in the navigation device, it is necessary to input the respective position information, and to search and set the route in order to go from the departure place to the destination.
The applicant of the present invention has already proposed several methods for inputting the position of departure and destination (for example, Japanese Patent Laid-Open No. 01-173820).
No. 02-048800). In these, an intersection is entered by a code number, or an initial letter or the like is entered from a menu screen to call a desired intersection name on the screen and an origin or the like is entered. In such a method, target registration positions such as departure points and destinations are divided into genres such as sightseeing, parking lots, restaurants, etc., and coded by regions such as prefectures and cities, and the code is input. ing. In that case, in addition to directly inputting the code number, a method of displaying a menu and sequentially selecting and inputting from the menu is also proposed. We also propose a method that has node data, connects the node data to define a road network, and inputs the position by coordinate values of east longitude and north latitude.

For example, in the case of a hotel, a symbol mark corresponding to the type of each facility, such as “H”, is stored in the memory, and a plurality of types of facilities are selected according to the type of the selected facility. There is proposed an information display device for selecting an arbitrary facility type from the above and displaying a symbol mark at the position where the facility exists on the map (Japanese Patent Laid-Open No. 62-15188).
(See Japanese Patent Publication No. 1).

[0007]

However, the conventional position input method such as the starting point and the destination, which is indispensable as an initial operation in the navigation device, takes time and effort to input a desired position as described above. There is a problem that it is not easy.

For example, in the code input method, since each position is defined by a special code number, a codebook is required, and the position cannot be input unless the codebook is referred to one by one. Moreover, the codebook is enormous because it contains all the codes, and it must be carried.

Further, in the menu system, a desired position cannot be input on one screen, and a desired position cannot be input unless a predetermined item is selected on each screen by sequentially switching a large number of screens. That is, since the display device used for the navigation device is mounted in a relatively easy-to-see space near the driver's seat, a compact device is adopted, and the amount of information that can be displayed at one time is small. Therefore, there is a problem that the screens are finely classified and the number of menu screens increases, and the input operation takes time and labor accordingly.

The coordinate input method also has the trouble that the position cannot be input without the coordinate table and the coordinate value of the position to be input must be retrieved from the coordinate table.

Further, in the information display device for displaying the symbol mark, since all the symbol marks are the same for each type of facility, a store according to preference, for example, a gas station or family restaurant of a specific series is distinguished from the symbol mark. You cannot choose. Moreover, when the symbol marks are displayed on the city map, the symbol marks may be concentrated in a narrow area, which makes it difficult to grasp the positional relationship between them.

The present invention is intended to solve the above-mentioned problems, and aims to improve the visibility by providing a mark so that it can be seen easily on a map.

[0013]

To this end, the present invention provides a landmark composed of map data, facility data including location information for each facility, the name of each facility, and a landmark pattern number, and a landmark pattern corresponding to the landmark pattern number. The information storage means for storing the pattern data and the processing means for obtaining the data stored in the information storage means and drawing the landmark pattern of each facility together with the map are provided, and the processing means includes the position information and the landmark pattern. A number is acquired from the facility data, a mark pattern corresponding to the acquired mark pattern number is acquired from the mark pattern data, and the acquired mark pattern is drawn on the map based on the position information. It is characterized by that.

Further, information storage means for storing position information for each facility, facility data including the name of each facility and a mark pattern number, and mark pattern data composed of a mark pattern corresponding to the mark pattern number, and a telephone number are stored. Input means for inputting, processing means for searching facilities included in the area code of the telephone number input by the input means and performing list drawing processing, and output means for outputting the list of the facilities subjected to list drawing processing by the processing means The processing means acquires a name and a mark pattern number from the facility data, acquires a mark pattern corresponding to the acquired mark pattern number from the mark pattern data, and draws the name and the mark pattern in a list. Characterized by processing or information storage means for storing telephone numbers, location information and identification information for each facility, and telephone numbers Input means for inputting, a processing means for searching a facility included in the area code of the telephone number input by the input means from the information storage means, and processing for drawing a list of identification information of the searched facility; Output means for outputting a list of facility identification information drawn by the processing means, and selecting means for selecting a destination from the list of facility identification information output by the output means. It is a thing.

[0015]

In the navigation device of the present invention, the landmark pattern is composed of map data, facility data including position information for each facility, the name of each facility, and a landmark pattern number, and a landmark pattern corresponding to the landmark pattern number. An information storage unit that stores data, and a processing unit that acquires the data stored in the information storage unit and draws a landmark pattern of each facility together with a map are provided.
The position information and the mark pattern number are acquired from the facility data, the mark pattern corresponding to the acquired mark pattern number is acquired from the mark pattern data, and the acquired mark pattern is mapped based on the position information. Since the drawing process is performed on the top, it is possible to provide a familiar mark on the map so that the visibility can be improved.

Further, the name and the mark pattern number are acquired from the facility data, the mark pattern corresponding to the acquired mark pattern number is acquired from the mark pattern data, and the name and the mark pattern are subjected to list drawing processing. By outputting a list of the identification information of and selecting the destination from the output list of the facility identification information, the facility information can be displayed on the list with familiar marks and names, and the destination can be selected. .

S database, 6 is an output means, and 7 is a TL database. The CPU 1 is a navigation processing device including various programs required for navigation such as a course guidance (navigation) program, a route search program, and a current position tracking program, and based on input information from the input unit 2 and the position detection unit 3. Launch the specified program and map database 4, GS database 5, TL
Take in the data stored in the database 7, process it,
Through the output means 6, the driver is provided with course guidance information, a menu at the time of setting the course, and other necessary information. The input means 2 is composed of a touch panel, a keyboard, etc., and a touch panel is attached on a display screen which constitutes a part of the output means 6, and inputs information such as a destination and a departure place. The position detecting means 3 is composed of a sensor group such as a distance sensor, a steering sensor, a geomagnetic sensor, etc. for detecting the traveling history and position of the vehicle, and tracks the current position of the vehicle by detecting the traveling distance and traveling direction of the vehicle. It is used to do. The map database 4 has characteristic information of the road network and its surroundings based on road network data and coordinate data as shown in FIG.
Has information about each gas station GS in the area targeted for navigation as shown in FIG.
The database 7 comprises the GS database 5 data points for gas stations contained within the same local area code of the telephone as shown in FIG. The output means 6 is composed of a display device such as a CRT, a liquid crystal display, a plasma display, etc., and a voice output device, and these are attached at a position near the driver's seat where the necessary information can be accurately transmitted to the driver, such as course guidance. It provides information.

In the map database 4, for example, when there is a road network consisting of intersection numbers I to VII and road numbers to ○ 14 as shown in FIG. 2, the intersection data is shown in FIG. 3, the road data is shown in FIG. 4, and the node data is shown in FIG. It has a data structure as shown in FIG.

As shown in FIG. 3, the intersection data includes the smallest road number corresponding to the intersection numbers I to VII among the roads starting at the intersection and the road ending at the intersection. It has the smallest road number, the position of the intersection (east longitude, north latitude), and the name of the intersection.

Further, as shown in FIG. 4, the road data includes the next road number among roads having at least the same start point, the next road number among roads having the same end point, and the intersections corresponding to road numbers to ∘14. It has information on the start point, end point, node string pointer, and road length by numbers. As is clear from the figure, the next road number among the roads with the same starting point,
The next road number among the roads having the same end point can be generated by searching the same number from the start point and the end point according to the intersection number. Further, the road length can also be calculated by integrating the position information of the next node string data.

In the node string data, as shown in FIG. 5, there is a node number at the head pointed by the node string pointer of the road data, and the node position (east longitude, north latitude) information about the node corresponding to the number is next. have. That is, a node string is formed for each road data. The illustrated example shows a node sequence with road numbers.

As is clear from the above data structure, the unit of road number consists of a plurality of nodes. That is, the node sequence data is a set of data relating to one point on the road, and when connecting the nodes is called an arc, the road is represented by connecting the arcs between the plurality of node sequences. . For example, regarding the road number, it is possible to access the node sequence data A000 from the node sequence pointer of the road data, and it can be recognized that the road number includes 15 nodes.

Further, when attention is paid to the intersection number V, for example, in the course where the starting point is the intersection number, first, the road number from the information of the road in which the intersection data appears, and then the "the same starting point of the road data regarding the road number Road number "
The road number ○ 12 is searched from the information of. Then, the road number ∘14 and then the same are retrieved from the similar information regarding the road number ∘12. Here, since the road number is the first road number, it can be determined that there is no other road number as the surrounding road. This also applies to the end point. In this way, by using the intersection data and the road data, it is possible to search the road numbers entering and leaving each intersection, and also it is possible to obtain the distance of the route connecting each intersection. Furthermore, by adding entry prohibition, right / left turn prohibition, traveling conditions such as road width, etc. to these data, it is possible to use them as information for performing the route search described later in detail, for example.

The GS database 5 is, for example, as shown in FIG. 6, position information such as telephone numbers, coordinate values of east longitude and north latitude, contact intersections for linking with the map database 4, and the like.
It has identification information such as the name of the gas station and its mark pattern. Therefore, when the course is set by the intersection row, the gas station on the course can be searched by searching the connected intersection of the GS database from the intersection, and the mark pattern of the gas station according to the coordinates of east longitude and north latitude. Etc. can be drawn on the course.

The TL database 7, as shown in FIG. 7, is the area code data including pointers to the local area code data,
It is composed of local area code data, which is a pointer to the GS data index, and GS data index, which is a pointer to the GS data index. Therefore, from this information, the number of gas stations included in the local area code can be known from an arbitrary telephone number, and the GS data of each can be read out.

In the navigation system according to the present invention, in the system having the above-mentioned structure, when GS data as shown in FIG. 6 is used as the mark data and the departure place is input by the telephone number, the TL database 7 is accessed from the telephone number. Then, the pointer of the GS data is read out, and the mark is drawn on the map of the course with the corresponding gas station as the starting point. Alternatively, if there is no corresponding gas station, the gas stations included in the local area code of the telephone number are displayed as a list and they are considered as candidates for the starting point. Then, the course will be guided to the destination starting from the gas station that was selected from the selected starting point.

FIG. 8 is a diagram for explaining the overall processing flow of the navigation device according to the present invention, and FIG. 9 is a diagram showing an example of the start screen of the GS near the current position. In the navigation device according to the present invention, first, the destination is input as shown in FIG. 8, and then the current position is input (steps-). The current position in this case is entered by a telephone number.

Next, the gas station within the area code area is searched for and the gas station GS near the current position is searched.
Is selected to draw a start screen of the GS near the current position with the gas station as the start position as shown in FIG. 9 (steps ~). And GS near the current position
Wait until the GS name area is touched on the start screen of, and confirm that it is touched, then guide the route according to the set course (steps ~
).

As described above, in the navigation device according to the present invention, if the telephone number of the gas station to be started is input, the course guidance to the destination can be started from the gas station as the departure point.
Even if you can not decide the gas station to start, if you enter the current position or a telephone number in the vicinity, the gas station included in the city code will select the gas station near the destination as the departure position,
It is easy to input the departure point.

Next, an example of the GS selection subroutine near the current position in the above processing will be described in more detail. FIG. 10 is a diagram showing an example of a GS selection subroutine near the current position, FIG.
Is a diagram showing an example of a GS data search subroutine in a station number area, FIG. 12 is a diagram showing an example of a search data initialization subroutine, FIG. 13 is a diagram showing an example of a correction start point / end point setting subroutine, and FIG. FIG. 15 is a diagram showing an example of a route search subroutine from the ground, FIG. 15 is a diagram showing an approach surrounding road search subroutine, FIG. 16 is a diagram showing an example of an optimum route condition setting subroutine, and FIG. 17 is an example of an end condition confirmation subroutine. FIG. 18 is a diagram showing an example of selecting the GS near the departure position.

In selecting the GS near the current position in the step of FIG. 8, as shown in FIG. 10, first, i) the station number area GS data is retrieved from the GS database through the TL database. GS in this area code area
In the data search, as shown in FIG. 11, first, the area code of the input telephone number is searched from the area code data of the TL database, and the number of the area code and a pointer to the area code data are stored in the work area. To do. Next, the local area number of the telephone number input by the number of the local area number is searched from the pointer position of the local area number data to the local area number data, and the pointer to the GS data index is stored. Then, the number of GS data included in the station number area is stored from the pointer position of the GS data index, and the number of GS data is stored by that number. Then, the data in the GS database is read and stored by the number of the GS data from the number of the GS data. The above returns. ii) Next, the search data is initialized. In this process, as shown in FIG. 12, the distance L (c) from the search start point to the intersection C is set to ∞, the search state flag F (c) and the search end flag F0 (c) are set to 0, and Set 0 to k. iii) Next, set the connecting intersections of the destinations to the search start intersections s0 and s1, set the distances L (s0) and L (s1) from the search start points of the intersections to the destinations, iv) Further, the number of GSs in the station number area is set to n, and the search end intersections e0 _i and e1 _i are set to the connecting intersections of the GS in the station number area. v) Next, a search start point and an end point are set. In this setting, as shown in FIG. 13, the search state flags F (s0) and F (s1) of the search start intersections s0 and s1 are set to "1" indicating that the search is in progress, and the search end intersections e0 _i and e1 _i are set. search end flag F0 (e0 _i), sets "1" indicating the search end to F0 (e1 _i). vi) Next, a route search from a destination, which will be described later (FIG. 14), is performed. vii) When the route search from the destination is completed as described above, among the intersections whose search end flag F0 (c) is 1,
An intersection having the minimum distance L (c) from the destination is searched, and the intersection is set as C _min . viii) Then, the gas station GS having C _min as the connecting intersection is set as the GS near the current position.

Next, the route search from the destination will be described.
In this process, as shown in FIG. 14, the flag F is not “2” (searched) and the distance L (c)
The intersection number c ₀ that minimizes is searched. An approaching surrounding road search subroutine is executed to search for surrounding roads starting from the intersection number c ₀ . Check whether there is a road around the road. If YES, the process moves to the next process, and if NO, the process moves to ◯ 11. The optimum route condition setting subroutine is executed to set road conditions and other conditions for searching for the optimum route. The intersection number at the starting point of the road is c ₁ and the length of the road is l. The distance P to the intersection at the end of the road is calculated. Calculate P = L (c ₀ ) +1. Here, L (c ₀ ) is the distance from the departure point to the intersection number c ₀ , and P is the distance from the intersection number c ₀ through the road (road under search) to the end intersection number c _1. . It is checked whether P <L (c ₁ ) and F (c ₁ ) ≠ 2. In the case of YES, the process proceeds to the next process ◯ 10, and in the case of NO, the process returns. Distance L from the departure point to the intersection number c _{1 being} searched
(C ₁ ) is P, and the flag F (c ₁ ) of the intersection number c ₁
Is “1”, and the road number R (c ₁ ) that has passed through to reach the intersection number c ₁ is the road number being searched. If NO in the process, set F (c ₀ ) to “2”.
Set to. ○ 10 Execute the end condition confirmation subroutine. ○ 11 It is checked whether or not the process is completed. If NO, the process returns to the process, and if YES, the process ends. By performing the above processing, the road number of the optimum course from the destination to the intersection number is set corresponding to each intersection number for each intersection number.

The approaching peripheral road search subroutine of the above processing is to perform the processing shown in FIG. That is, it is checked whether or not the surrounding road is searched for the first time. If YES, the process proceeds, and if NO, the process proceeds.
The road number at which the current intersection c ₀ is the end point is extracted from the intersection data and stored. By referring to the road data, the forbidden road at the road number from the intersection c ₀ under search is extracted. Check whether the road just taken out is a prohibited road. YE
In the case of S, the process proceeds, and in the case of NO, the next process is performed. The road just taken out is stored as a surrounding road, and the process returns. The road number having the same end point as the previously searched road and the next road number is extracted from the road data. Check whether the road searched first and the road just retrieved are the same. If YES, the process moves to the next process, and if NO, the process returns. It is judged that there is no surrounding road and the process returns.

The optimum route condition setting subroutine of the process shown in FIG. 14 performs the process shown in FIG. That is, the size W and the length l of the surrounding road are read from the road data. It is checked whether the size W of the surrounding road is 1 or less. If YES, the process proceeds to the next process, and if NO, the process proceeds. Let l be the length obtained by multiplying the length l by a. That is, if a road having D greater than 1 is a normal wide road and a road having a D of 1 or less is a thin road, the thin road is a
The distance is doubled. Therefore, a is a number greater than 1. From the road data, the guidance unnecessary data of the road that has passed to the intersection currently searched is read. Check whether there is a surrounding road that matches the guidance-free data. If YES, the process returns, and if NO, the next process is performed. Further, a value obtained by adding bm to the length l is set as a new length l and the process is returned. That is, an intersection requiring guidance such as turning left or right is calculated as bm and added to the intersection that does not require guidance.

Then, in the termination condition confirmation subroutine of the process ○ 12 shown in FIG. 14, it is checked whether or not the search termination flag F0 (c ₀ ) of the intersection number c ₀ to be searched is "1" as shown in FIG. , YES, the searched number k is incremented by 1 and, for example, an end flag is set on condition that k becomes n.

GS near the departure place selected in this way
Among the gas stations GS in the area code area of the departure place, as shown in FIG. 18B, is the gas station GS that connects to the intersection on the shortest route from the destination.
On the other hand, for example, as shown in (a) of the same figure, the mark pattern or name of the gas station GS in the station number area of the place of departure is displayed as an option on the screen, and the gas station GS to start the guidance can be selected by touch. You may do it.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, in the above-mentioned embodiment, the telephone number is adopted as the selection information, and the departure place is inputted by the telephone number.However, it is used in combination with the menu method, the code input method, and the coordinate input method in which other selection information is adopted. Of course, the input method may be appropriately selected. Further, although the telephone number can be input only at the departure point, the telephone number may be similarly input at the destination, the guidance starting point and the like. Then, in this case, a gas station within the area code area of the destination city may be set as the destination, and the gas station may be guided from the departure place. In addition, FIG.
Instead of the gas station as shown in the screen, other service marks such as supermarkets and shops, and public facilities such as stations may be used as landmarks.
