Perform management. Therefore, even when state information that includes only dynamic state item information but does not include static state item information is received, information on the static state of the facility obtained from the state information including static state item information in the past is lost. It will never be. Therefore, information indicating the application state can be provided to the user as much as possible.

  Here, the above-described in-vehicle information providing system further includes storage means for storing facility information in which the static state item information of each facility is registered in advance, and in the facility management information updating unit, the state information receiving unit includes The received state information includes the dynamic state item information, does not include the static state item information, and the static state item information is registered in the facility management information of the facility corresponding to the received state information. If not, the dynamic state item information of the facility management information of the facility corresponding to the received state information is updated to the dynamic state item information included in the received state information, and the facility corresponding to the received state information The static state item information indicated by the facility information of the facility corresponding to the received state information may be set in the static state item information of the facility management information.

In this way, even for a facility that can receive only state information including only the dynamic state item information, the static state of the facility can be presented to the user using facility information prepared in advance. It becomes like this.
Moreover, when providing the memory | storage means which memorize | stored such facility information, in the vehicle-mounted information provision system, the said static status item information contained in the status information which the said status information receiving means received further received the status information The facility that updates the static state item information of the facility information with the static state item information included in the received state information when the facility state information is different from the static state item information indicated by the facility information Information updating means may be provided.

By doing in this way, it becomes possible to update the facility information of the facility prepared in advance with the current status using the state information received from outside the vehicle for the facility whose static state has changed.
Further, in the above in-vehicle information providing system, the state information receiving means includes a VICS receiver that receives VICS road traffic information as the state information, and a predetermined state information provider via a mobile communication network. And a wireless communication device that receives the state information.

  Here, in the above in-vehicle information providing system, the facility may be a parking lot or a service area. In addition, when the facility is a parking lot, the dynamic state item information may be information including at least information indicating whether the parking lot is full / empty.

  As described above, according to the present invention, it is possible to provide an in-vehicle information providing system capable of providing the user with as much detailed facility state information as possible.

  In such a configuration, the traffic information processing unit 18 of the navigation device 1 of the in-vehicle system 100 processes the traffic information received by the VICS receiver 6 from the VICS information broadcast station 400. In addition, the traffic information providing server 300 is accessed via the wireless communication device 7 to receive the traffic information from the traffic information providing server 300 and perform the processing.

  The types of traffic information that can be received by the VICS receiver 6 include traffic jams (sections / degrees, etc.), accidents (places, etc.), temporary regulations (sections / places, contents, etc.), travel times (sections, required time) Etc.), parking lot (location, name, full availability, etc.), and other (caution message etc.). Further, there are three levels of the content of the traffic information, and only the traffic information of level 3 is accompanied by position information that can identify the road section / point targeted by the traffic information on the map. In this embodiment, the VICS receiver 6 receives this level 3 traffic information from the VICS information broadcast station 400.

  On the other hand, the traffic information acquired from the traffic information providing server 300 via the wireless communication device 7 is also equivalent to the traffic information received by the VICS receiver 6. However, even if the traffic information received by the VICS receiver 6 and the traffic information acquired from the traffic information providing server 300 represent the same object and event information, the information items are different. The level of detail of information may be different.

  The traffic information processing unit 18 stores the traffic information received by the VICS receiver 6 and the traffic information acquired from the traffic information providing server 300 in the memory 15 as reception information data. As shown in FIG. 3a, the received information data is a traffic information number given as an identifier of the received traffic information and a reception indicating whether the traffic information is received by the VICS receiver 6 or received from the traffic information providing server 300. It includes information such as media, traffic information reception time, traffic information traffic jam / accident / temporary regulation / travel time / parking area, etc., and information that is the content of the received traffic information. Here, the content of the traffic information whose information type is parking lot always includes parking lot identifier, parking lot position information, parking lot name, and full / vacant information indicating whether the parking lot is full / empty. In addition, the traffic information whose information type is parking lot may include the number of accommodated vehicles, parking lot structure, vehicle type restriction, and business information. In addition, the parking lot identifier, parking lot location information, parking lot name, number of accommodations, parking lot structure, vehicle type restrictions, and sales information are information items similar to the information items of the same name registered in the parking lot record of the map data. is there.

  In addition, when the traffic information processing unit 18 receives new traffic information, the traffic information processing unit 18 presents existing received information that represents past information about the same object as the received traffic information based on the type and position information of the traffic information. A process of extracting and deleting data, or deleting received information data whose reception time indicates that the received information data is no longer valid when viewed from the current time or current position is also performed.

  Further, the traffic information processing unit 18 performs a parking lot state management process to be described later based on such received information data, and also generates a parking lot state information shown in FIG. . As illustrated, the parking lot state information is provided for each parking lot that has received the traffic information. The parking lot state information is information indicating the current state of the corresponding parking lot, and the information items include an update date and time indicating the date and time when the parking lot state information is updated, a parking lot identifier, parking lot position information, parking lot information. It can have a parking lot name, accommodation capacity, parking lot structure, vehicle type restrictions, sales information, and fullness information.

Now, in such a configuration, the current state calculation unit 12 of the navigation device 1 repeatedly performs the following processing.
That is, the current state calculation unit 12 has a current position estimated from the outputs of the vehicle state sensor 4 and the GPS receiver 5 in the vicinity of the current position determined last time indicated by the map data read from the map data storage unit 11. Map matching processing with the map, etc., the most probable coordinates as the current position, the most probable direction as the current traveling direction, and the most probable link as the current traveling link, the current position and the current The traveling direction and the traveling link are determined and set in the memory 15.

  Further, the control unit 16 receives a destination setting from the user via the operation unit 2 and the GUI control unit 13 in response to a user destination setting request, and sets this in the memory 15. Then, the route search unit 14 is made to search for a recommended route to the destination. The route search unit 14 reads the road unit data in the necessary geographical area from the map data storage unit 11, and the route with the lowest cost that first follows the traveling link from the current position set in the memory 15 to the destination. Is calculated as a recommended route based on a predetermined cost model using a link cost or the like described in the link table, and the calculated route data of the recommended route is set in the memory 15.

In addition, when the current position set in the memory 15 becomes near the destination, the control unit 16 determines that the destination has arrived, and also performs processing for clearing the destination and the recommended route set in the memory 15. .
The guide image generation unit 17 then maps the map display range calculated by the control unit 16 according to the current position set in the memory 15 or the point designated by the user with the cursor and the map display scale set at that time. An image is drawn based on a drawing unit of map data stored in the map data recording unit. In addition, a guide image in which a traffic information graphic representing a current position, a recommended route, a destination, a traffic jam section, an accident point, and a temporary restriction section set on the map image is drawn on the map image is drawn. Generated and displayed on the display device 3. Here, the guidance image generation unit 17 stores the traffic information figure representing the traffic jam section, the accident point, and the temporary restriction section on the map image, and the information type is the traffic jam section, the accident point, and the temporary restriction section. Is generated based on the received information data, and is drawn. Further, the guide image generating unit 17 stores an icon representing a parking lot among icons drawn as a part of a map image based on the icon unit of the drawing unit. Based on the parking lot state information corresponding to the parking lot in the full state and the parking lot in the empty state are drawn in different expressions, so that the user can indicate the full / empty state of the parking lot from the guide image. Be able to grasp immediately. Moreover, the control part 16 will also perform the process etc. which display the content of the corresponding parking lot state information on the display apparatus 3, if the icon of the parking lot where the corresponding parking lot state information exists is selected by the user. The icon unit of the drawing unit includes information for associating the icon with the parking lot in advance.

  FIG. 3c shows an example of the guide image displayed on the display device 3 in this way. In the example shown, the display range of the map is determined based on the current position. The guide image is a map image 301 around the current position including an icon 302 representing a parking lot and a current position mark 303 representing the current position. When a recommended route is set, a route graphic 304 representing a recommended route within the map display range is displayed on the map image 301 in the guide image. Further, when the destination is included in the display range, the destination mark representing the destination is also displayed on the map image 301. The parking lot icon 302 is displayed in a different form depending on whether the parking lot is full / empty. In the illustrated example, the full parking lot icon 302a (full) is displayed with a lower contrast than the empty parking lot icon 302b (empty). Reference numeral 310 in the figure denotes parking lot state information displayed in the form of a balloon from the selected icon 302b (empty) when the user selects the parking lot icon 302b (empty). The parking lot state information window describing the contents of is shown.

Hereinafter, the parking lot state management process performed by the traffic information processing unit 18 to generate parking lot state information based on the reception information data will be described.
FIG. 4 shows the procedure of the parking lot state management process.
As shown in the figure, in this process, first, it waits for reception information data of the parking lot of the information type to be generated (step 402). Then, if reception information data of the parking lot of the information type is generated, it is checked whether or not the parking lot state information for the parking lot targeted by the reception information data is already stored in the memory 15 (step 404). If stored, the process proceeds to step 406. Here, the parking lot targeted by the reception information data and the parking lot targeted by the parking lot state are determined according to the difference between the information items of the parking lot identifier, the parking lot position information, and the parking lot name. Hereinafter, the information items for identifying the parking lot such as the parking lot identifier, the parking lot position information, and the parking lot name information item will be collectively referred to as a parking lot identification information item.

On the other hand, if the parking lot state information for the parking lot targeted by the reception information data is not already stored in the memory 15 (step 404), new parking lot state information for the parking lot targeted for the reception information data is generated. Then, the parking lot identification information item included in the received information data is set and stored in the memory 15 (step 416).
Then, it is checked whether or not the parking lot record for the parking lot targeted by the received information data is included in the parking lot data of the map data (step 418).

  On the other hand, when the parking lot record for the parking lot targeted by the received information data is included in the parking lot data of the map data (step 418), the number of accommodations registered in the existing parking lot record, Information items indicating the static state of the parking lot, such as the parking lot structure, vehicle type restrictions, and sales information, are set in the parking lot state information generated in step 416 (step 420), and the process proceeds to step 406. Hereinafter, the information items indicating the static state of the parking lot, such as the number of accommodated vehicles, the parking lot structure, the vehicle type restriction, and the business information information item, are referred to as static state information items.

  In step 406, the parking lot state information about the parking lot targeted by the reception information data is extracted as the target parking lot state information. And the information item which shows the dynamic state of parking lots, such as full space information, among the information items of object parking lot state information is cleared, and the value of each information item contained in received information data The value of the corresponding information item in the status information is updated (step 408). At this time, for information items not included in the received information data, the value of the information item in the target parking lot state information is maintained. Here, in the following, information items indicating the dynamic state of the parking lot such as full space information are collectively referred to as a dynamic state item. However, here, only full / vacant information is included in the dynamic state information item.

  Next, it is checked whether or not the value of the static state information item of the target parking lot state information has been changed by the process of step 408. If not changed, the process returns to step 402. On the other hand, if it has changed, it is checked whether or not the parking lot record for the parking lot targeted by the target parking lot state information is included in the parking lot data of the map data (step 412). Return to the process from 402. On the other hand, if it is included, among the information items included in the static state information item registered in the parking lot record, information in which a value different from the same information item of the target parking lot state information is registered The value of the item is updated to the value of the same information item of the target parking lot state information (step 414), and the process returns to step 402.

The parking state management process has been described above.
Hereinafter, an example of processing by such parking state management processing will be shown.
FIG. 5 shows a first processing example.
In this example, the parking lot identification information (parking lot identifier, parking lot position information, parking lot name) from the VICS information broadcasting station 400 at time t1 as traffic information about the parking lot with the parking lot name “H Tongnam No. 3” And traffic information including only dynamic state information items (full / vacant information), and then parking lot identification information, static state information items (parking lot structure, vehicle type restrictions, business information) and dynamic state at time t2. Traffic information including information items is acquired from the traffic information providing server 300, and thereafter, traffic information including only parking identification information and dynamic state information items is received from the VICS information broadcast station 400 at time t3. If it is about. The parking lot record for the parking lot with the parking lot name “H Tongnam No. 3” is not included in the map data.

In this case, for each traffic information, a1 reception information data is created at time t1, a2 reception information data at time t2, and a3 reception information data at time t3.
And at time t1, as shown in b1, the parking lot name in which only the dynamic state information item included in the reception information data of a1 is set out of the static state information item and the dynamic state information item. The parking lot state information about the parking lot of “H Tongnam No. 3” will be generated.
At the next time t2, since both the static state information item and the dynamic state information item are included in the reception information data of a2, the parking lot state information includes the reception information data of a2, as indicated by b2. The static state information item included in the information is newly set, and the dynamic state information item is updated to the dynamic state information item included in the received information data of a2.

  At the next time t3, since only the dynamic state information item is included in the reception information data of a3, the parking state information is as shown in b3, and the reception information data of the dynamic state information item is a3. The static state information item is maintained as it is, and updated to the dynamic state information item included in.

Next, FIG. 6 shows a second processing example by the parking state management process. This example is similar to the example of FIG. 5, as traffic information about the parking lot with the parking lot name “H Tongnan No. 3”. Traffic information including only the parking lot identification information and the dynamic state information item is received from the VICS information broadcasting station 400 at time t1, and then the parking lot identification information, the static state information item, and the dynamic state information item at time t2. When the traffic information including the parking information is acquired from the traffic information providing server 300, and then the traffic information including only the parking lot identification information and the dynamic state information item is received from the VICS information broadcast station 400 at time t3. belongs to. However, the 2nd processing example is a thing about the case where the parking lot record about the parking lot of this parking lot name "H Tongnan 3rd" is contained in map data.

Also in this case, similarly to the first processing example of FIG. 5, for each traffic information, the reception information data of a1 at time t1, the reception information data of a2 at time t2, and a3 at time t3. Reception information data is created.
Then, at time t1, as shown in b1, the static state information item of the parking record of c1 is set as the static state information item, and the dynamic information included in the reception information data of a1 as the dynamic state information item The parking lot state information for the parking lot having the parking lot name “H Tongnam No. 3” in which the state information item is set is generated.

  And at the next time t2, since both the static state information item and the dynamic state information item are included in the reception information data of a2, the parking lot state information is a static state information item as shown in b2. Is updated to the static state information item included in the reception information data of a2, and the dynamic state information item is updated to the dynamic state information item included in the reception information data of a2. . At this time, the match between the static state information item of the parking record of c1 and the static state information item of the parking state information of b2 is checked, and among the static state information items of the parking record of c1 As for the information item whose value does not match the corresponding information item of the parking lot state information of b2, the value is updated to the value of the corresponding information item of the parking lot state information of b2, as shown in c2. Is done. That is, the value of the static state item of the parking lot record is updated to a value representing the latest static state of the parking lot. In the illustrated example, since the value of the sales information in the static state item of the parking record of c1 is different from the value of the sales information of the reception information data of a2, the sales information of the parking record as shown in c2 The value is updated to the value of the sales information of the reception information data of a2 registered in the parking lot state information of b2.

  At the next time t3, since only the dynamic state information item is included in the reception information data of a3, the parking state information is as shown in b3, and the reception information data of the dynamic state information item is a3. The static state information item is maintained as it is.

The embodiment of the present invention has been described above.
As described above, according to the present embodiment, when traffic information including only dynamic state information and not including static state information items is received, traffic information including the last received static state information item is received. Is used as the current static state information item of the parking lot. In addition, when traffic information including only dynamic state information items and not including static state information items is received, traffic information including static state information items has not been received before that, traffic information map data The static state information item indicated by the parking lot record prepared in is used as the current static state information item of the parking lot.

Therefore, information indicating the state of the parking lot can be provided to the user as much as possible.
In addition, the static state information item of the parking lot record prepared in the map data is also used for facilities that receive only traffic information that includes only the dynamic state information item but not the static state information item. The status information can be presented to the user.
In addition, using the traffic information, the update to align the static state information items of the parking lot record prepared in the map data with the current situation, which is necessary when there is a change in the static state of the actual parking lot, It can be done automatically.
In addition, although the case where the state of a parking lot was managed was demonstrated above, this embodiment can be similarly applied to the management of the state about arbitrary facilities, such as a service area. For example, in the case of a service area, the service area identifier, service area location information, and service area name are used as service area identification information items, and the number of accommodations, attached facility facilities, and sales information are used as static status information items. What is necessary is just to perform the process similar to the above parking lot management process by making a state etc. into dynamic state information.
