  Hereinafter, a preferred embodiment in which the present invention is applied to a car navigation apparatus having a function capable of receiving an area-specific information receiving system from terrestrial digital broadcasting will be described with reference to the drawings.

1 and 2 are schematic explanatory views showing a car navigation device 2 according to the first embodiment.
Reference numeral 1 denotes a broadcasting station that performs terrestrial digital data broadcasting (ISDB-T).
In this embodiment, as an example of the digital data broadcasting area-specific information, attribute data such as the price or business hours of goods or services related to usage location data on the map, weather forecast data, and road congestion information are used. Have.

Here, the use location data is POI, services, and other data such as various stores, facilities, and tourist spots, and is previously recorded in a storage unit such as a hard disk, a DVD-ROM, or a CD-ROM of the car navigation apparatus 2 together with map data. May be distributed via the Internet, or may be distributed as regional information.

The attribute data of the use location includes data such as the price of each product or service, the available time, the handling of coupons and points, special offers, special offers such as special services, and advertisements.
This attribute data is distributed as region-specific information together with the use location data.
Alternatively, in correspondence with the usage location data recorded in the storage unit, only the attribute data is distributed, in addition to the usage location data and attribute data recorded in the storage unit, the addition having attribute data, It may be corrected.

In the car navigation device 2, a receiving unit 3 for a moving body, a GPS unit 4 shown as a current position input unit, a storage unit 5 storing map data and the like, a display 6, and an input means 7 serve as a controller. It is connected to the processing unit 10.
The receiving unit 3 includes a mobile tuner (DSTB) connected to the antenna 3 a, receives digital terrestrial television broadcasts, acquires regional information from digital data broadcasts distributed simultaneously, and passes through the interface unit 8. The data is converted into data that can be processed by the processing unit 10 of the car navigation device 2.

The processing unit 10 acquires the current position data of the user from the GPS unit 4, calls up the map data of the corresponding area from the map data storage unit of the memory 5 based on the position data, and displays it on the display.
The position data may be acquired by using a known configuration that uses an autonomous navigation unit as an auxiliary.
Further, in the processing unit 10, based on the current position data, the area code determination means 11 determines the area code to which the position data belongs (see FIG. 4).

In this embodiment, the region-specific information obtained from the receiving unit 2 is attribute data such as weather forecast, road traffic jam information, region-specific POI (service) information, etc. as region-specific information corresponding to the region code. (See FIG. 3).
Use location data is, for example, basic data such as various stores, facilities, points, etc. classified into categories such as gas stations, parking lots, convenience stores, restaurants, hospitals, government offices, leisure spots, night view spots, etc. (Position data, area code, name data, category data) and the attribute data.

In addition to a controller that controls the device (not shown), the processing unit 10 includes the area code determination unit 11, a category search unit 12 that allows a user to search by category from the usage location data, and the presence or absence of recommendation or the degree of recommendation. Recommendation determining means 13 for determining is provided (see FIG. 4).
The category search means 12 extracts the use location data belonging to the category from the use location data, using one category selected from the category group by the user as a search condition.
The recommendation deciding means 13 ranks recommendation presence / absence or recommendation degree based on recommendation conditions such as price and arrival time from the attribute data (see FIG. 3).

As an example with reference to FIG. 5, when searching for “gas station”, first, “gas station” is input as the category search condition by the input means 7, and gasoline is searched from the usage data by the category search means 12. Extract stand data.
Next, a recommendation condition is input by the input means 7.
The recommendation condition is set as a keyword such as “price”, “arrival time”, “direction”, “privilege”, etc. from the attribute data, and the keyword is input.

  For example, when “price” is input as the recommendation condition and the recommendation determination unit 13 is executed, the “price” data is called out from the extracted attribute data of the gas station, and the comparison is performed relatively.

In the recommendation determination means 13 of the processing unit 10, the position data of the gas station extracted by the category search means 12 and the predicted route for moving from the current position to the gas station based on the current position data are determined by the route determination means ( (Not shown), and the predicted travel distance of the determined predicted route is measured.
Then, it is determined whether or not the predicted moving distance is within a predetermined range (for example, a distance that can be traveled after the empty lamp is lit), and a gas station within the range is extracted.

Next, road traffic congestion information corresponding to the predicted route is acquired from the regional information, and the predicted arrival time from the current position to the gas station is measured.
Data obtained from an analog data receiving unit such as VICS may be used as the traffic congestion information.
Based on the predicted arrival time, it is determined whether or not the predicted arrival time falls within the range of business hours of the attribute data of the gas station.
Here, when the business hours data is not included in the attribute data, the recommendation level is set to 0 (none) or “unknown” is displayed.

Next, the gasoline price of the gas station is compared according to price, and the recommendation level is set in descending order of price.
At this time, for example, when a special sale period is set as privilege information of attribute data of a certain gas station, it is determined whether or not the current date falls within the above period. Special prices can be compared.

Thereby, the recommendation degree about the "price" of the gas station that can be used from the current point is displayed.
In addition, when “privilege information” is included in the attribute data, a bonus display can be added separately.
Alternatively, the recommended travel distance and the predicted arrival time may be set in ascending order, and the total recommendation may be determined by combining this with the price recommendation.
Alternatively, all those satisfying certain conditions may be “recommended”.
For example, stores that can use coupons, stores that handle common points, and the like may be displayed as “recommended”.
The regional information may include privilege data for distributing coupons that can be used at a predetermined store.

Thereby, as shown in FIG. 6, the icon of a gas station is displayed on the screen of a display with the said recommendation degree (or recommendation).
In FIG. 6, G represents a gas station icon, and the number of stars represents the recommendation level. For convenience of explanation, the map on the screen is omitted.
In the present embodiment, the image of the display 6 is a touch panel, so that the attribute data and the PR data can be displayed in a small window on the screen when the gas station icon is touched. To be able to see.

Similarly, when a parking lot is selected, vacant information of the parking lot may be transmitted as attribute data as region-specific information, and this may be received to extract a parking lot with vacant information.
However, the parking lot availability information received from an analog data receiving unit such as VICS may be used.
In this case, the category search means 12 extracts the parking lot data having a vacancy with the vacancy information.

Next, the recommendation determination unit 13 makes a determination based on, for example, “estimated arrival time or predicted arrival distance” and “price” as recommendation conditions.
That is, a predicted route from the current position to the parking lot is assumed, and then the predicted arrival distance is calculated.
Alternatively, the predicted arrival time is calculated by acquiring the traffic jam information of the predicted route from the road information (traffic jam information) of the regional information as necessary.
The degree of distance recommendation can be set in the order of short arrival prediction distance or arrival prediction time.

Next, the parking fee (price) in the attribute data is called, and the price recommendation degree of the parking lot is set in ascending order of price.
Then, the final recommendation degree for display is determined by combining or separately combining the distance recommendation degree and the price recommendation degree.
Thereby, a parking lot can be displayed on the screen of a display with the said recommendation degree (refer FIG. 5).

Next, when searching for a night view spot, as shown in FIG. 7, the category search means 12 designates “night view spot”, and then the recommendation determination means 13 is executed.
The night spot usage location data may be recorded together with the map data in advance, or may be distributed as area-specific information. Based on these data, the category search means 12 uses the night scene spot usage location data. Data is extracted.

Next, the recommendation determining means 13 determines a predicted route from the extracted night view spot and the current position, and determines the weather forecast of the night view spot at the predicted arrival time.
That is, a route determination unit provided in the processing unit 10 determines a predicted route from the current position to the night view spot.

Next, the predicted arrival time is calculated based on the road traffic information received from the regional information or the analog data receiving unit such as VICS.
Based on the predicted arrival time, weather forecast data of the area to which the night view spot belongs is acquired from the regional information.
Then, the recommendation level is determined according to the weather. For example, it is determined that the highest recommendation level is clear if it is clear, the next recommendation level is clear, and that fog and rain are not recommended.

As a result, in addition to the recommendation level, predicted route, predicted arrival time (distance), and weather forecast data can be obtained. In addition to the recommendation level, these data may be externally displayed as necessary.
If the night view spot is in a store or facility and there are restrictions on the use time, it can be determined whether or not the use is possible by determining whether or not the predicted arrival time is within the available time of the attribute data. Can be determined.

Thereby, a night view spot can be displayed on the screen of a display with the said recommendation degree.
If the night view spot belongs to a region other than the region to which the current position belongs, the region code is input as a condition for acquiring the region-specific information, and the region-specific information (weather forecast data) And road traffic congestion information), and the region-specific information of the corresponding region may be acquired.

  In this way, the icon corresponding to the selected category is displayed on the map on the display screen together with the recommendation level based on the current position, so that the user can receive support for selecting the usage site to be moved.

Next, the image of the car navigation device shown in FIG. 8A shows an example in which the traveling direction of the usage place recommended from the current position is displayed on the screen using the circular wheel H with the current position as the center.
The small window in the lower left of the figure displays the usage points with recommendations (two stars) that do not enter the screen. For example, a point is provided along the outer periphery of the screen, and the extension direction and By flashing the point, it may be displayed that there is a recommended usage location in the extension direction.
According to this, the use location can be easily found by changing the scale ratio of the screen.

Next, the car navigation system cannot examine feng shui, direction, and other fortune telling, which uses the direction of the user's current position as a reference.
For this reason, fortune-telling data consisting of good and bad heading data corresponding to the use location data on the day or for a certain period is distributed as the regional information.
Then, if an azimuth meter based on the current position is displayed, it is possible to display the good and bad luck in all directions.
Further, if there is position data of the current position and the destination, the direction of the destination can be easily calculated.

Therefore, the usage location data extracted by the category search means 12 may be displayed on the screen indicating in which direction it can be recommended from the viewpoint of fortune-telling.
Alternatively, as described above, whether or not the usage location data to which the recommendation level is given in advance by the recommendation determining unit 13 in the data extracted by the category search unit 12 is recommended in terms of fortune-telling. May be displayed on the screen (see FIG. 10).
Fortune-telling information varies depending on the date and time, and also varies depending on the category that the user intends to use. Therefore, the latest fortune-telling data can be acquired from regional information by receiving digital data broadcasting.

For example, when a restaurant is searched by the category search means 12, the direction can be displayed from the extracted restaurant position data and the current position data, and the direction of travel can be recommended depending on which direction is good.
In order to make this direction intuitive, as shown in FIG. 8 and FIG. 9, a circular wheel H is displayed on the screen of the display with the current position as the center. The direction of 12) is displayed and has a compass shape.

Then, when the recommendation condition is input as “fortune telling” by the input means 7 and the recommendation determination means 13 is executed, the current recommendation is made according to the selected category and individual data (birth date, blood type, etc.) of the user. The direction and the direction of good or bad can be displayed (see FIG. 9).
In this case, today's fortune-telling data (such as a combination of category type and direction and good or bad data, or a combination of direction and good or bad data) is included as regional information, and based on this, the bad or bad is determined. .

  Further, in combination with the recommendation by the fortune telling, the recommendation level determination means 13 inputs different recommendation conditions (for example, price) from the category extracted as described above, and determines the recommendation level as described above. You may make it display on a display combining this and the azimuth | direction of the fortune telling (refer FIG.8 (b)).

As a result, the user can select a store in a category on the extension of the recommended direction or close to the recommended direction, and determine the travel route.
In this case, it is possible to display the wheel H and the direction of the evil on the map displayed on the screen without performing category search, and the user may freely decide the destination.
In the figure, R indicates a restaurant icon. An asterisk indicates the recommendation level. For convenience of explanation, the map on the screen is omitted.

In the present invention, the usage location data having the attribute data is distributed from the digital data broadcast together with the regional information such as weather forecast and traffic jam information, and is displayed in combination with the map data via the interface unit. ing.
On the map, use location data such as stores, facilities, and predetermined points is displayed as icons. Touching the icons displays small windows on the screen, and attribute data and PR of the stores, facilities, or points. Information can be displayed.

  In addition, for example, a reservation icon is added to the icon, a reservation content (time, number of people, course name, etc.) is input, and the mobile phone (shown in the figure) connected to the car navigation device 2 is input. It is also possible to make a reservation by mailing to the mail receiving section of the broadcasting station 1 and transferring the mail to the store or facility.

Next, in this car navigation device, the direction of disaster prediction and disaster information may be displayed.
The navigation device receives regional information based on the current GPS location information, but the regional information includes location data of disaster locations where damage is predicted or currently damaged by weather forecasts, road information, etc. And disaster data such as disaster severity.
Disaster prediction or information includes, for example, typhoon approach information, tornado forecasts, tsunami forecasts, road blockage information due to accidents and disasters, evacuation information, etc. The predicted time, the time when the disaster continues, the extent of the disaster, and the like are recorded in advance as attribute data.

Therefore, as shown in FIG. 11, when the disaster data is acquired from the above regional information, the processing unit 10 warns the disaster location (position data) by the warning direction determination means based on the current position data obtained from the GPS. The direction toward the disaster place is determined as the warning direction.
In addition, the processing unit 10 is provided with warning level determination means, and depending on the severity of the disaster damage, the severity of the risk, and the distance from the current position to the warning point (degree of approach), the risk of disaster It is preferable to determine the degree of warning indicating the degree of.

Then, the disaster spot is displayed on the screen in combination with the map data, and when the disaster spot is outside the range of the screen, it is displayed as a warning direction or a safety direction.
For example, when the wheel H indicating the azimuth is used, a portion corresponding to the warning azimuth is not cut and the azimuth is not displayed, and the type of disaster and the warning level (the number of black stars in the illustration) in the cut out blank portion. It is easy to recognize if the safety azimuth display configuration is displayed (see FIG. 12).

In the present invention, all or a part of the usage location data distributed by digital data broadcasting is auxiliary information linked to usage location data such as fixed POI information recorded in the memory (hard disk, DVD, etc.) of the car navigation device 2. It may be.
That is, the fixed POI information recorded together with the map data in the memory of the car navigation apparatus is displayed at a predetermined position together with the map data on the display screen.

On the other hand, usage location data distributed by digital data broadcasting is composed of information that is not in the fixed POI information or the latest information, and is input via the interface unit 8 to supplement the fixed POI information, or It is good also as a structure which can be rewritten and displayed on map data.
