Next, the operation will be described. FIG. 3 is a flowchart showing schematic processing steps of the navigation device according to the first embodiment of the present invention. When the information providing service using the narrow area communication system is started, information on the genre to be output stored in the backup memory is read out and restored to the work area (step ST1). Next, it is determined whether or not there is a genre change based on a user operation or the like (step ST2). If there is a genre change based on a user operation or the like, the genre of the output target is changed according to the content of the genre change, and the updated genre of the output target is stored in the work area (step ST3). Next, it is determined whether or not the narrow area communication system data has been received (step ST4). When the mobile object passes under the roadside device 1 transmitting the narrow area communication system data and the narrow area communication system data is received,
The narrow-area communication system data to be input is selected, and the narrow-area communication system data to be output is stored in a predetermined storage means so as to be presented or presented to the user (step ST).
5). Next, it is determined whether or not the information providing service using the narrow area communication system is to be terminated based on the designation of the user or the like (step ST6). If the process is not to be ended, the process returns to step ST2. When ending the processing, information relating to the genre to be output set in the work area is stored in the backup memory (step ST7), and the processing ends. It should be noted that, in the above-described processing, the determination regarding the presence / absence of a genre change based on a user operation or the like is performed first, and the determination regarding the presence / absence of reception of the short-range communication system data is performed later. The order may be reversed. On the other hand, if it is determined in step ST6 that the process is not to be terminated, the process proceeds to step ST6.
Although the configuration has been described in which the control returns to Step 2, the control may return to either Step ST2 or Step ST4 as appropriate according to the elapsed time. That is, it may be configured to normally return to step ST4 so as to maintain the standby state for the narrow area communication system data for a certain period of time.
Further, the information on the genre to be output is read out from the backup memory to the work area. It is also possible to adopt a configuration in which the information relating to the genre to be output is read out from the backup memory to the navigation ECU 14 after rewriting and updating.

FIGS. 4 and 5 are flow charts showing processing steps for setting a genre to be output and determining a priority order for the set genre. When the information providing service using the narrow area communication system is started and the process of changing the genre to be output is performed in step ST3, first, the interface unit 8 performs a connection determination with an external unit, If a unit is connected, the genre relating to data transmitted and received using the external unit is written as a genre to be output in the work area set in the external memory 13 (step ST11). Next, the setting status of a password, such as a password that is scheduled to be used and stored in a backup memory or the like in advance or a password newly input by a user, is detected, and if a password is set, the password is set. Is written in the work area (step ST1).
2). Here, the password refers to a user who specifies a genre desired by the user based on a contract or agreement between the user and an information provider such as a provider or a navigation maker that provides information in a narrow-area communication system. Means a symbol string composed of numbers, characters, and the like. Therefore, if a password is not given, the user cannot acquire information on the genre specified by the password, even if the genre is desired by the user. For example, when the password for specifying the weather information is “ABCD”, by setting ABCD in the password input unit, the weather information is selected from the received narrow-area communication system data, and the weather is displayed on the navigation map. , Such as displaying a mark meaning cloudy, rainy, or the like. In setting the password, it is also preferable to use an anti-theft symbol assigned as a unique encryption only to the navigation device in consideration of the security of the navigation device.

Next, when a navigation device-related program provided by a navigation maker or the like using a predetermined medium (DVD, CD-ROM, etc.) is upgraded, the navigation program is described in the upgraded program. The current genre is written in the work area (step ST13). Since the information provided by the narrow-area communication system changes every day, genres may be newly established or deleted frequently, and in order for the navigation device to recognize these genre changes, version upgrades are required. It is necessary to execute the program.

Next, when the individual medium is set by the user and the reading of the data from the individual medium is confirmed, the genre described in the individual medium is written in the work area as the genre to be output (step ST14). ). Note that the individual media stores programs, data, and the like provided by the information provider to the user so that the user can acquire various narrow-area communication system data provided by the narrow-area communication system in various modes. Means the media. For such individual media, for example, the genre is read by using a program provided by a navigation maker to read genre-related information stored in individual media created and sold by a provider based on common data specifications and the like. It is assumed that the usage mode is such that new installation or erasure is performed. Furthermore, the individual media can store not only genre-related data but also a processing program for narrow-area communication system data. By executing such a processing program, the user can obtain more significant information. For example, "Provider: Mitsubishi Electric" for individual media
If it is described, it is possible to select and output narrow-area communication system data related to a predetermined genre for which Mitsubishi Electric is an information provider from among the received narrow-area communication system data Becomes

Next, regarding the genre to be output set in the work area based on the processing of restoring the genre from the backup memory and the processing in steps ST11 to ST14, if necessary, a predetermined word or phrase by the user is used. Based on processing such as input of a symbol string composed of characters or the like or arbitrary selection by the user for the displayed genre, only the genre desired by the user is left in the work area as a genre to be output, and Is deleted from the work area (step ST15). As described later, each genre has four identifiers (a narrow-area communication system identifier, a provider identifier, a format identifier, and a data content identifier) defined hierarchically so as to constitute identification information.
And classified into categories having various inclusion levels. Therefore, it is possible to set only the genre desired by the user in the work area by the user inputting a symbol string that matches or partially matches a symbol string that constitutes an identifier for specifying a desired genre. .

Next, for a plurality of genres to be output set in the work area, it is determined whether or not the order in which narrow-area communication system data belonging to each genre is presented to the user is specified. (Step ST16). If the order of presentation by the user for each genre is specified by the user, the output target genres set in the work area are sorted according to the specified order and rearranged in the order of higher rank (step ST17). ).

If it is determined in step ST16 that the order has not been specified by the user, the following order determination processing (step ST18 to step ST18) is performed.
21: see FIG. 5) to determine the order related to the output target genre set in the work area. In this order determination process, in order to quantitatively evaluate the rank of each genre, a rank score serving as a priority index is set for each genre, and the genre to be output is set according to the magnitude of the rank score. Determine the order.

First, ranking points are assigned to genres to be output in accordance with the degree of correlation with a predetermined position or area (step ST18). For example, if there is something related to the current location surrounding area, +2 points are added to the ranking score of the corresponding genre, and if there is something related to the destination surrounding area or the waypoint surrounding area, the ranking score of the corresponding genre is added. +1 point is added. Next, a ranking score is given according to the degree of correlation with a predetermined route (step ST19). For example, when a route from the current location to the destination is being searched, if there is something related to the area along the searched route, +1 point is added to the ranking score of the corresponding genre. Next, a ranking score is given to the display unit 5 according to the degree of correlation with the area displayed on the screen (step ST20). For example, when a map around the current location is displayed on the display unit 5, if there is a map related to the area specified by the map displayed on the screen, +1 point is added to the ranking score of the corresponding genre.

The above-mentioned ranking score giving processing (step ST1)
When the ranking points for each genre are determined by 8 to step ST20), the output target genres set in the work area are sorted according to the ranking points and rearranged in descending order of the ranking points (step ST21). Step ST1
7 or in step ST21, if the order of presentation to the user relating to the genre to be output is determined, the control / arithmetic unit 4 receives the narrow area based on the genre sequentially set in accordance with the order. The communication system data is selected, and the narrow-area communication system data is output to the display unit 5 or the audio notification unit 6, and the display unit 5 or the audio notification unit 6 presents information on the narrow-area communication system data to the user. (Step ST22). In the first embodiment, the ranking score assigning process is performed in step ST18.
To ST20, the rank score giving process may be performed using only one of the steps ST18 to ST20, or the steps ST18 to ST2.
The rank score giving process may be implemented by combining any two steps from 0. Also, the above step ST1
To Step ST7 and Steps ST11 to ST11
It is assumed that the process according to step ST22 is executed using the control / arithmetic unit 4.

FIG. 6 is a diagram showing an example of management information relating to narrow area communication system data transmitted from the narrow area communication system. In FIG. 6, reference numeral 21 denotes a narrow-area communication system identifier indicating a narrow-area communication system installer, reference numeral 22 denotes a provider identifier indicating a provider of data transmitted from the narrow-area communication system, and reference numeral 23 denotes a data format of the narrow-area communication system data. The format identifier 24 is a data content identifier indicating the data content of the narrow area communication system data. As for the short-range communication system identifier 21, the provider identifier 22, the format identifier 23, and the data content identifier 24, the identification content, the dependency between the identifiers, and the like are defined based on a hierarchical structure such as a tree structure. Therefore, it is possible to make the newly-created identifier dependent on the higher-order identifier, make the newly-provided provider identifier 25 depend on the narrow-area communication system identifier 21, and make the newly-created format identifier 26 depend on the provider identifier 22. And the newly established data content identifier 27
Can be made dependent on the format identifier 23, and a new genre can be newly established for each. For the transmitted narrow-area communication system data, as an example, a transmission form in which the management information is transmitted collectively and effective data scheduled to be presented to the user following the management information is transmitted, In this case, as the management information, a data position or an address at which the individual information is transmitted is given together with each identifier for identifying the individual narrow-area communication system data.

The control / arithmetic unit 4 includes a set of identifiers (a narrow area communication system identifier 21-a provider identifier 22-a format identifier 23-a data content identifier 24) for specifying a genre to be output set in a work area. By comparing a set of identifiers for specifying a genre related to each of the narrow-area communication system data transmitted from the narrow-area communication system (a narrow-area communication system identifier 21-a provider identifier 22-a format identifier 23-a data content identifier 24). When all the identifiers match or when a prescribed identifier matches, the transmitted narrow area communication system data is determined to belong to the genre of the output target, and the narrow area communication system data is determined. Is output to the display unit 5 or the audio notification unit 6.

FIG. 7 is a diagram showing an example of a display screen when a genre desired by the user is selected. Step ST
11. Selection of a genre related to the external unit executed in step 11, selection of a genre related to the password executed in step ST12, selection of a genre related to the upgraded program executed in step ST13, and execution in step ST14 Based on the selection of the genre related to the individual media to be performed, only the switches related to the genre to be output are actively displayed (displayed without shading in FIG. 7) and the switches related to the genre not set as the output target in the work area Is not active displayed (indicated by hatching in FIG. 7). If a predetermined symbol string such as "Mitsubishi" is input to the keyword input unit, in step ST15, only the genre desired by the user based on the symbol string is set as a genre to be output in the work area. While leaving
Other genres are deleted from the work area. Further, when the output order as shown in FIG. 7 is input to the output order input unit, in step ST17, the output target genres set in the work area are sorted and according to the input output order. Rearrange. Also, if nothing is input to the output order input section,
By executing the order determination process from step ST18 to step ST21, the output target genres set in the work area are sorted and rearranged according to the magnitude of the ranking score. Then, based on the genre sequentially set in accordance with the determined presentation order to the user, the control / calculation unit 4
Selects the received short-range communication system data, and presents information on the narrow-area communication system data to the user via the display unit 5 or the voice notification unit 6.

FIG. 8 is a diagram showing an example of a transition of a display screen when information transmitted by the narrow area communication system is presented to the user. In FIG. 8, (a) shows an example of a screen display related to purchase of a product and payment of a fee for the product, which is performed by two-way communication between a communication device as an external unit and a narrow area communication system, b) shows an example of a screen display related to traffic information set by inputting a password, (c) shows an example of a screen display related to an advertisement described in an individual medium, and (d) shows an example of a version-up program. It shows an example of a screen display related to the described new traffic information. In this embodiment, in the traffic information, the section indicating traffic congestion is for each road,
The new traffic information differs in that the detailed section of the traffic congestion and the distance of the traffic congestion are indicated. By reading the upgraded program in this way, more effective information or user-friendly information can be obtained at any time. It becomes possible to acquire. In addition, regarding the switching method between the respective screen displays, the screen may be switched at predetermined time intervals based on the user presentation order determined in step ST22 by the user's selection. Regardless, the screen may be switched in response to the user pressing the switch that is active in FIG. In the case where information related to the narrow area communication system data is sequentially displayed at predetermined time intervals based on the order as input to the output order input unit in FIG. 7, screen (a)-> screen ( d)->
The display screen is switched in the order of screen (c)-> screen (b).

Next, for each type of genre belonging to the information provided from the narrow area communication system, a method of setting a work area which is considered to be suitable for the type will be described. As shown in FIG. 8A, the setting of the genre related to the use such as performing the two-way communication with the short-range communication system and automatically charging is performed as shown in step ST11 with the external unit. It is preferable to set the genre based on the connection determination. As a specific example of such a genre setting, in addition to the automatic charging for the store fee as shown in FIG. When a mobile phone is used as the external unit, it is assumed that various genre settings are performed using the method shown in step ST11 according to the function of the mobile phone. Further, a transmission / reception unit using a narrow area communication system and transmission / reception via a telephone line using a mobile phone may be used in combination. For example, it is assumed that data is transmitted to a predetermined server via a telephone line based on the content received by the short-range communication system.

When the navigation device is used merely as provided information display means, the genre of provided information may be provider help information, news,
Recommended spots, advertisements, entertainment, free software, and the like. Since these genres do not have a direct relationship with the navigation, it is preferable to set the genre by taking out the media used for navigation from the drive 17 and inserting individual media into the drive 17. is there.

Also, genres related to navigation, for example, traffic information such as traffic congestion, road information for notifying the maintenance status of lane markers necessary for automatic driving, and weather information for displaying a weather mark on a navigation map. With regard to the genres related to, for example, the media used for navigation cannot be removed from the drive 17,
Since there is no need to perform two-way communication with the narrow-area communication system, it is preferable to set the genre using a password.

As described above, according to the first embodiment, a narrow area communication system data receiving section 2 for receiving information provided by a narrow area communication system, and a genre setting section 3 for setting a genre to be output. And a plurality of identifiers for specifying a genre relating to each of the narrow-area communication system data received by the narrow-area communication system data receiving unit 2 and a plurality of identifiers for specifying the respective output target genres set in the genre setting unit 3. The control / arithmetic unit 4 that selects and outputs narrow-area communication system data belonging to the genre to be output by comparing and comparing the identifier with the identifier is provided, so that the genre to which the information desired by the user belongs belongs. By setting the information in the genre setting unit 3 in advance, only the information desired by the user is selected from the information transmitted by the narrow area communication system, and There is an effect that can be presented to.

Further, the identification information for specifying the genre is composed of four identifiers, ie, a narrow area communication system identifier 21, a provider identifier 22, a format identifier 23, and a data content identifier 24, which are defined hierarchically. Since the classification of the genre can be performed hierarchically from the upper concept to the lower concept, it is possible to acquire information using a comprehensive expression at various levels with respect to a set of information desired by the user, thereby improving usability. The effect that it can improve is produced.

Further, as shown in step ST11, the control / arithmetic unit 4 is configured to set the genre relating to the connected external unit in the genre setting unit 3 as the genre to be output. Since the genre relating to the external unit is automatically set as the genre to be output and the information relating to the genre is presented to the user, there is an effect that the user can save the trouble of setting the genre and improve the usability. .

Further, as shown in step ST12, the control / calculation unit 4 is configured to set the genre specified based on the password input by the user in the genre setting unit 3 as the genre to be output. Therefore, there is an effect that it is possible to realize the construction of a system that enables the user to selectively obtain significant information based on a contract concluded between the user and the navigation maker or the provider.

Further, as shown in step ST13, the control / arithmetic unit 4 is configured to set the genre described in the upgraded program in the genre setting unit 3 as the genre to be output. There is an effect that it is possible to appropriately install or delete a genre according to the transition of information provided by the area communication system.

Further, as shown in step ST14, the control / arithmetic unit 4 is configured to set the genre described in the individual media in the genre setting unit 3 as the genre to be output. By receiving the provision of the individual media, it is possible to realize the construction of a system that enables the user to selectively obtain significant information.

As shown in step ST15, the control / arithmetic unit 4 determines, for a plurality of genres to be output set in the genre setting unit 3, based on the symbol string input by the user, the symbol string. Since the genre related to the user is left in the genre setting unit 3 and the genre not related to the symbol string is deleted from the genre setting unit 3, the genre related to the information desired by the user can be narrowed down, so that the genre is more efficient. This has the effect of realizing a simple screen display.

As shown in step ST18, the control / arithmetic unit 4 determines the degree of correlation between each genre and a predetermined position or area for a plurality of genres to be output set in the genre setting unit 3. Is configured to determine the rank of each genre when presenting information belonging to each genre to the user based on the information, so that information that is more important or information that is predicted to be more desired by the user is determined. Can be preferentially presented to the user, and more effective screen display can be realized when presenting the narrow-area communication system data to the user.
