Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle navigation device, and more particularly to an on-vehicle navigation device for searching for and informing facilities belonging to a specified genre.

[0002]

2. Description of the Related Art An in-vehicle navigation device includes a map data storage device such as a CD-ROM and a DVD-ROM in which map data is recorded, a display device such as a liquid crystal display device, a gyro, and a GPS (Global Position).
a vehicle movement detection device that detects the current position and the traveling direction of the vehicle, such as a vehicle speed sensor and a vehicle speed sensor. The map data including the current position of the vehicle is read from the map data storage device, and based on the map data. The map image around the vehicle position is displayed on the display screen, and the vehicle position mark (location) is superimposed on the map image. The map image is scrolled according to the movement of the vehicle, or the map image is displayed on the screen. By fixing and moving the vehicle position mark, it is possible to see at a glance where the vehicle is currently traveling.

[0003] Normally, a navigation system for a vehicle is provided with a route guidance function that enables a driver to easily travel to a desired destination without making a mistake on a road. According to this route guidance function, the lowest cost route from the starting point to the destination using the map data is automatically searched by performing a simulation calculation such as the horizontal search method or the Dijkstra method, and the searched route is guided. It is stored as route data, and the guidance route is displayed on the map image with a different color from the other roads and is drawn thicker, or when the vehicle approaches an intersection where the route on the guidance route should be changed within a certain distance. In such a case, an arrow indicating a course is drawn at an intersection on a map image, or guidance is provided by voice so that the driver can easily grasp an optimal route to the destination.

[0004] The cost is obtained by multiplying a constant corresponding to the road width and the road type (regular road or highway) based on the distance. Therefore, even if there are two routes having the same distance, the driver can specify, for example, whether to use a toll road, whether to give priority to time, and the like.
The costs will be different.

Further, some of such navigation apparatuses have a search function for searching for a point or a facility from an address, a telephone number, a facility name, or the like. In the map data storage unit, data on facilities are classified and stored according to genres, such as convenience stores, gas stations, restaurants, and the like. In the navigation device, the user specifies the genre, and the specified genre near the current position of the vehicle is designated. Some facilities have a peripheral facility search function of searching for a facility belonging to the facility and displaying a search result on a screen, or searching for a guidance route to the searched facility and guiding a vehicle along the guidance route.

[0006] Some genres are classified into a plurality of hierarchies and store facility information. For example, the genres are divided into three hierarchies of a large classification, a middle classification, and a small classification.
Classified into "shops", "food stores", "entertainment", etc., and the "categories" of the large category are classified into "convenience stores", "department stores", "supermarkets", etc. “Ya” is classified into “family restaurants” and “fast food”. Each middle category is also classified into a small category such as “chain store”. For example, the middle category "convenience store" is "Seven-Eleven",
It is classified into "Lawson", "Family Mart" and the like.

When performing a facility search, a user performs a facility search by designating search genres in the order of a large category, a middle category, and a small category. For example, first, a large category “shop” is selected. The large category “shop” includes medium categories such as “convenience store”, “department store”, and “supermarket”. When the user selects a desired category (eg, “convenience store”) from the middle categories,
In the classification of “convenience store”, chain store names such as “Seven-Eleven”, “Lawson”, and “Family Mart” are stored as the classification. From among these, the user specifies a chain store name of a desired convenience store and instructs a search. The navigation device searches for facilities belonging to the selected category within a predetermined range from the current position of the vehicle, and notifies the driver of the search result along with the distance from the current position of the vehicle.

As described above, the search genre is classified into a large classification, a middle classification, a small classification and a hierarchical structure, and the genre is stored. By specifying the genre classification at each stage as the search genre, a predetermined position is determined from the vehicle position. The facility belonging to the designated classification is searched from the facilities located within the range, and the search result is reported to the driver. When the user selects one facility from the search results, a map centering on the selected facility is displayed. When the user presses the destination button while the map is displayed, the designated convenience store is displayed. Is set as the route guidance destination, and the navigation device searches for the lowest cost route from the current position of the vehicle to the destination. Then, the route obtained as a result of the search is set as a guidance route, and the vehicle is guided along the guidance route. If no facility belonging to the search genre exists within a predetermined range from the current position of the vehicle, the user is notified that there is no facility of the desired genre nearby. When the user knows that there is no facility of the desired genre near the vehicle, the user performs another facility search by specifying another genre.

[0009] Recently, a navigation device operated by voice has been developed. Enter the name and genre of the facility by voice, search for the entered facility,
A facility belonging to the input genre is searched, and the search result is notified to the user.

[0010]

When performing a facility search by specifying a genre, a facility that the user does not want may be searched. For example, a user wants to go to a convenience store, but the chain store “convenience store A” has been frequent and tired recently.
When it is desired to find a convenience store other than “convenience store A” near the vehicle, the name of a convenience store other than “convenience store A” is input to the navigation device and searched. In this case, the user is "convenience store A"
A chain store “convenience store B”, which is a convenience store other than, is searched as a search genre. When the search is performed using “convenience store B”, a convenience store belonging to the chain store “convenience store B” located within a predetermined range from the current vehicle position is searched.

The user desires that any convenience store other than the chain store “convenience store A” may be any of the chain store “convenience store B” and the chain store “convenience store C”. Thus, when the search is performed with “convenience store B” as the search genre, actually, the facility belonging to “convenience store B”
Even if the facility belonging to “convenience store C” is a convenience store closer to the vehicle position, unless the search condition is set to “convenience store C” and the user performs a search, “convenience store C” is closer to “convenience store B”. It is difficult to know that there is.

In other words, when searching for a facility belonging to a certain genre, if it is desired to search for a facility other than the facility which does not belong to the user but belongs to the genre, the search condition must be changed and the search repeated. In some cases, it is not possible to respond to actual user requests.

[0013] From the above, it is an object of the present invention to input a genre to be excluded, perform a facility search using a higher genre to which the genre to be excluded belongs as a search condition, and exclude facilities belonging to the excluded genre included in the search result. To provide an in-vehicle navigation device for providing notification.

[0014]

According to the present invention, there is provided an on-vehicle navigation device for searching for and informing facilities belonging to a designated genre, a facility which classifies and stores the genres to which the facilities belong in a plurality of layers. Storage means, search exclusion genre designating means for specifying a genre to be excluded from search, search means for searching as a search genre a genre to which the genre specified by the search exclusion genre specifying means belongs, and search by the search means This is achieved by an in-vehicle navigation device including: a notification unit that excludes a facility belonging to the search exclusion genre from the search results and notifies the user of the facility.

That is, with the above-described configuration, the genres of facilities are classified and stored in a plurality of layers, and the genre to be excluded from the search is specified, so that the higher genre to which the exclusion genre belongs is searched. As a search, and excluding the facilities belonging to the search exclusion genre from the search result, and can be notified.

Further, according to the present invention, when there is only a facility belonging to a search exclusion genre in the search result, it is notified that there is no corresponding facility, and a facility belonging to the search exclusion genre is reported. This is achieved by an on-board navigation device.

That is, according to the above, by specifying a genre to be excluded from the search, when a higher genre belonging to the exclusion genre is searched as a search genre, the search results include only facilities belonging to the exclusion genre. In this case, it is possible to know that there is no facility belonging to the desired genre in the vicinity, and to know facilities belonging to the search exclusion genre.

Further, according to the present invention, there is provided an in-vehicle navigation apparatus for searching for and informing facilities belonging to a designated genre, a facility storage means for classifying and storing the genres to which the facilities belong in a plurality of layers, Search exclusion genre specifying means for specifying a genre to be excluded from search, search means for searching as a search genre a genre to which the genre designated by the search exclusion genre specifying means belongs, and a facility searched by the search means It is achieved by an in-vehicle navigation device having a notifying unit for rearranging and informing the facilities that do not belong to the search exclusion genre to the upper rank and the facilities that belong to the search exclusion genre to the lower rank.

In other words, with the above-described configuration, by specifying a genre to be excluded from the search, a higher genre to which the search exclusion genre belongs is searched as a search genre. The facilities that do not belong to the search genre can be rearranged and the facilities that do not belong to the search exclusion genre can be rearranged and reported.

Reference numeral 15 denotes a speaker, and reference numeral 16 denotes a bus.

The map data storage unit 1 stores map data. In addition to the map data, facility information for facility search is stored in a plurality of hierarchical structures for each genre.
The facility information is stored in a configuration as shown in FIG. As shown in FIG. 2, the genre to which each facility belongs has a three-layer structure of a large classification, a medium classification, and a small classification. A plurality of middle classifications belong to the large classification, and a plurality of small classifications belong to each middle classification. For example, "convenience store" is classified as a medium category, but "convenience store" belongs to a large classification "store" which is a higher classification, and a small classification " Chain store names such as "Seven-Eleven" and "Lawson" are stored. Further, data indicating the name and position of each facility is stored below the small classification. As described above, each facility belongs to each of the small categories, the small categories also belong to the respective middle categories, and the middle categories also belong to the respective large categories and are stored.

The control section 5 controls the entire navigation device, and has a facility search function for searching for a guidance route to a set destination and for searching for facilities belonging to a specified genre. Based on the search genre input by the user operating the operation unit 7 or the search genre input from the microphone 12, from the map data around the vehicle read from the map data storage unit 1, facilities belonging to the input genre are identified. The search is performed, the search result is displayed on the display device 10, and the speaker 15 is notified by voice. When a word indicating negative together with the search genre is input, the control unit 5 performs an exclusion genre search described later.

FIG. 3 is a diagram showing an example of a search genre input. FIG. 3A shows an example in which a genre is input without including a word indicating exclusion, for example, an example in which the user inputs "Seven-Eleven". The control unit 5 determines whether the input genre is classified into a large category, a medium category, and a small category, and registers the category as a decision key. Here, “Seven-Eleven” is registered in the sub-category confirmation key. Next, the control unit 5 registers a higher-level classification to which the input genre belongs as a determination key. Here, the middle category is “convenience store”, the major category is “shop”,
Both are registered in the confirmation key.

The control unit 5 searches for facilities belonging to the genre "Seven-Eleven" located within a predetermined range from the current position of the vehicle, using the lowest genre registered in the confirmation key as the search genre, and searches the searched facilities for the vehicle position. Notify in order from the nearest.

FIG. 3B shows an example in which a genre to be excluded is input. When “other than Seven-Eleven” is input, the control unit 5 detects a word “other than” that denied the genre “Seven-Eleven” from the input, determines that the genre “Seven-Eleven” is in a small category, Register as a negative key. Next, what is the middle category and the large category, which are the genres higher than the small category “Seven-Eleven”, is specified and registered in the confirmation key. In this example, the middle category is “convenience store” and the major category is “shop”, which are registered in the confirmation key.

The control unit 5 searches for facilities belonging to the genre "convenience store" located within a predetermined range from the current position of the vehicle, using the lowest genre registered in the confirmation key as the search genre. Thereafter, facilities belonging to the genre “Seven-Eleven” registered in the negative key are excluded from the search results, and the results are reported in order from the closest to the vehicle position.

FIG. 4 shows an example in which a search for excluding "fast food" which is a genre stored in the middle category in the facility information is performed. "Other than fast food"
Is input, the control unit 5 detects the genre “fast food” and “other” meaning negation, determines that the genre “fast food” is in the middle category, and Register to the negative key. Next, the upper class to which "fast food" belongs is determined and registered in the confirmation key. Here, the genre “meal” is registered as a major classification confirmation key.

The control unit 5 searches for facilities belonging to this genre using the lowest genre registered in the confirmation key as a search genre. In this example, facilities belonging to the genre "meal" are searched, and thereafter, facilities belonging to the negative key "fast food" are excluded from the search result.

As described above, when the user inputs an undesired genre at the time of the facility search, the facility is searched using the higher genre to which the inputted exclusion genre belongs as the search genre, and the facilities included in the exclusion genre are searched. Can be reported as a search result.

FIG. 5 is a diagram showing an example of an excluded genre search. Here, a search example in the case where the user inputs “other than Seven-Eleven” is shown. As shown in FIG. 5 (a), when the control unit 5 inputs "other than Seven-Eleven",
"Seven-Eleven" is a genre based on words entered
Is detected, and "Seven-Eleven" is registered as the negative key of the small category, and the upper genre to which "Seven-Eleven" belongs is registered as the final classification key of the middle category and the large category.

Next, based on the map data in the map data storage unit 1, the control unit 5 sets a predetermined range from the current position of the vehicle as a search range, and classifies the lowest order of the finalized key registered in FIG. Search for facilities belonging to. The example illustrated in FIG. 5B is an example illustrating a search result of facilities belonging to the genre “convenience store”. After that, the control unit 5
From the search result of (b), the facilities belonging to the negative key “Seven-Eleven” are excluded, and the result is as shown in FIG.
That is, only by inputting a genre to be excluded by the user, a search can be performed using a higher genre to which the genre belongs as a search condition, and a facility that belongs to the exclusion genre can be excluded from the search result and reported.

FIG. 6 is a diagram showing an example of exclusion genre search when the user inputs "other than fast food". If the user enters "other than fast food"
The control unit 5 detects “fast food”, which is a word indicating a genre, from the input words and detects “other”, which is a word indicating negation. Register with. And
The higher class to which "fast food" belongs is determined and registered in the confirmation key. Here, as shown in FIG. 6A, “meal” is registered as a large classification confirmation key, and “fast food” is registered as a middle classification negative key.

When the search key is registered, the control unit 5 selects the lowest genre registered in the confirmation key from among the search keys registered in FIG. 6A (in this example, a large category of “meals”). Is searched within a predetermined range from the vehicle position. When a facility belonging to the genre “meal” is searched, FIG.
As shown in (b), each classification, facility name, and position information (longitude, latitude) are read.

Next, among the facilities searched in FIG. 6B, the control unit 5 determines the facilities belonging to the negation key registered in FIG. 6A (in this example, "fast food" of the middle category). Remove from the search results. Thus, as shown in FIG. 6C, facilities that belong to the genre “meal” and do not belong to the genre “fast food” are listed.

As described above, by inputting a genre to be excluded at the time of facility search, a facility search is automatically performed with a higher genre to which the genre to be excluded belongs as a search genre. You can search for facilities that exclude.

FIG. 7 is a diagram showing an operation flow at the time of facility search in the on-vehicle navigation device of the present invention. First,
The operation starts when the user operates the operation unit or inputs search conditions by voice (step S10).
1). The control unit 5 refers to the facility information stored in the map data storage unit 1 and determines which category of the hierarchical structure the genre included in the search condition input in step S101 is (step S102). For example, if the genre of the input condition is “Seven-Eleven”, referring to the facility information stored in the map data storage unit 1,
It is determined to be a small category, and if the input genre is "fast food", it is determined to be a middle category.

Next, the control unit 5 determines whether or not a word indicating exclusion of the input search condition is included (step S103). If the input condition includes a word indicating exclusion, the control unit 5 performs control. The unit 5 registers the input genre in the corresponding category of the negative key (step S104), and subsequently registers the higher genre to which the input genre belongs as the determination key (step S105).

Then, the control unit 5 performs step S104,
Among the search keys registered in 105, the genre of the lowest classification registered in the confirmation key is set as a search genre, and facilities belonging to the genre are searched for within a predetermined range from the vehicle position (step S106).

The control unit 5 excludes facilities belonging to the genre registered in step S104 from the search results among the facilities searched in step S106 (step S10).
7).

In step S103, if the input condition does not include a word indicating exclusion, the control unit 5 registers the genre of the input condition in the classification key determined in step S102 (step S108). Registered in the confirmation key of the upper category to which the genre belongs (step S10)
9).

Then, the control section 5 executes step S108,
A genre registered in the lowest category of the finalization key among the registration genres registered in 109 as a search genre is
A facility belonging to the search genre within a predetermined range from the vehicle position is searched (step S110).

Step S107 or step S110
Then, based on the search result, the facility information is displayed on the display screen in a list from the closest to the vehicle position, or the search result is notified by voice from the speaker 10 (step S11).
1).

As described above, by specifying the genre to be excluded by the user, the upper genre to which the search exclusion genre belongs is set as the search genre, and the facilities located around the vehicle belonging to the genre are searched, and the facility is excluded from the search result. The user can be notified excluding facilities belonging to the genre.

In the description of the above embodiment, the exclusion genre is deleted from the search result of the higher genre to be notified, but the search result may be notified by lowering the priority of the facility belonging to the exclusion genre. It is possible. In other words, a facility may be searched using a higher genre to which the specified search exclusion genre belongs as a search genre, and the searched facilities may be notified in order of facilities that do not belong to the search exclusion genre and facilities that belong to the search exclusion genre. .

If no candidate facility remains when deleting a facility belonging to the excluded genre from the search results, it is notified that there is no facility that meets the user's search condition, May be reported. In this way, even if a facility that meets the user's desire is not found, it can be easily known that only facilities belonging to the excluded genre exist around the vehicle.

The present invention has been described with reference to the embodiments.
The present invention can be variously modified in accordance with the gist of the present invention described in the claims, and the present invention does not exclude this.

[0048]

As described above, according to the present invention, a facility is searched for by using a higher genre to which the search exclusion genre belongs as a search genre, and the facility which belongs to the search exclusion genre is excluded from the search result and is notified. The user can search for a desired facility simply by inputting a genre to be excluded from the search, which is convenient.

Further, according to the present invention, a search is performed using a higher genre to which a genre to be excluded belongs as a search genre, and when only facilities belonging to the exclusion genre are searched, it is notified that there is no corresponding facility. At the same time, the facility belonging to the exclusion genre is notified, so that it is possible to know that there is only a facility of that genre in the vicinity without repeating the search many times, and it is possible to save the user's trouble.

Further, according to the present invention, when a search exclusion genre is designated, a facility search is performed using a higher genre to which the search exclusion genre belongs as a search genre, and facilities that do not belong to the search exclusion genre are ranked higher in the search results. Since the facilities belonging to the search exclusion genre are rearranged and reported, the desired facility can be easily selected from the search results, which is convenient.
