  In addition to the above, ID = 03 indicating content reproduction conditions, ID = 04 indicating the expiration date of content, ID = 05 indicating content provision time, target point information (advertisement information of a content distribution source company, coupon information, etc. ) Indicating ID = 10, ID = 20 indicating the playback point (information providing point) of the content pop-up, ID = 30 indicating transition information (information specifying the screen (transition destination) to be displayed next), skewer search ID = 40 indicating detailed information used for realizing the above, ID = 60 indicating driving support information, ID = 80 indicating preference data, and the like may be included.

  Content information created in advance including the information of each ID is stored in the storage unit 34, and at the time of distribution, the control unit 31 selects content information to be distributed among these pieces of content information.

  That is, the information of each ID is not necessarily included in the content information, but is included in the content information as necessary. For example, it has information characterized by some content information ID00-05, and some other content information has information characterized by ID00-ID02, ID50, ID51. Note that ID00, ID01, and ID02 are basic information, and all content information has information of these IDs.

  The storage unit 34 stores static information and dynamic information of each parking lot registered in advance in the center device 30. Since the static information of the parking lot is similar to the example of the parking lot DB shown in FIG. 4, illustration and description thereof are omitted. Specifically, the dynamic information of the parking lot is stored in association with each parking lot ID. The dynamic information is updated by the control unit 31 at regular intervals so that information as close as possible to the current state can be provided.

  The communication unit 35 includes a communication interface for performing DSRC communication with the roadside wireless devices 20A and 20B, and a communication interface for performing IP communication with the roadside wireless device 20B and the wireless communication access point 20C. Communication processing by each communication method is executed according to communication control.

Next, the operation will be described.
With reference to FIG. 9, the flow of processing of the center device 30, the roadside wireless devices 20A and 20B, and the vehicle-mounted device 10 when content information is distributed will be described.
As shown in FIG. 9, first, when the engine of the vehicle C is started and the power of the vehicle-mounted device 10 is turned on (step S1), the control unit 4 generates characteristic information of the vehicle-mounted device 10 and updates the storage unit 3c. Write to the link information storage area 3c1 (step S2). The control unit 4 obtains characteristic information by inquiring each unit such as the display unit 1e, or by reading information stored in the storage unit 1f in advance, and writes it in a corresponding region of the uplink information storage region 3c1. In practice, the control unit 4 outputs control information instructed to write to the DSRC control unit 3a, and the DSRC control unit 3a writes the information to the uplink information storage area 3c1.

  Thereafter, when the vehicle C starts traveling and enters the mutual communication area Z of the roadside apparatus 20A or 20B (area-in), the roadside apparatus 20A or 20B detects the vehicle C, and the DSRC control unit of the vehicle-mounted device 10 3a starts the connection process by the DSRC communication with the uplink information storage area 3c1 (steps S3a and S3b). That is, the roadside apparatus 20A or 20B transmits a DSRC radio wave and establishes a communication path when a response from the vehicle-mounted device 10 is obtained. When the roadside apparatus 20A or 20B establishes the communication path, the roadside apparatus 20A or 20B transmits notification information indicating that the connection is completed to the center apparatus 30 (step S4a). On the other hand, the DSRC unit 3 of the vehicle-mounted device 10 outputs notification information indicating that the connection is completed to the control unit 4 (step S4b).

Next, when the roadside apparatus 20A or 20B requests the DSRC unit 3 of the vehicle-mounted device 10 to transmit information in the uplink information storage area 3c1, the DSRC unit 3 is written in the uplink information storage area 3c1. Is transmitted to the roadside apparatus 20A or 20B (step S5). The characteristic information is transmitted to the center apparatus 30 via the roadside apparatus 20A or 20B.
Next, the control unit 4 generates uplink information and writes it in the uplink information storage area 3c1 (step S6).

The center apparatus 30 periodically polls the vehicle-mounted device 10 (step S7), and requests the uplink information written in the uplink information storage area 3c1.
The DSRC unit 3 of the vehicle-mounted device 10 transmits the uplink information stored in the uplink information storage area 3c1 to the center device 30 via the roadside radio device 20A or 20B in response to polling from the center device 30 ( Step S8).

The center apparatus 30 reads the content information according to the received characteristic information and uplink information among the content information stored in the storage unit 34, and transmits the content information to the vehicle-mounted device 10 (step S9).
For example, if the language that can be supported by the characteristic information is “Japanese” and the uplink information is “member information”, “search position information”, “mesh code information”, “search condition”, etc. Content including parking lot dynamic information (ID = 50) indicating the dynamic information of the parking lot that matches the “search condition”, which is around the position according to “search position information” and “mesh code information”. Information is selected and distributed to the vehicle-mounted device 10.
In the vehicle-mounted device 10, the control unit 4 stores the received content information in the storage unit 1f (step S10).

  Thereafter, when all the content information to be distributed by the center device 30 is distributed, the control unit 31 generates message information for notifying the end of distribution and transmits the message information to the vehicle-mounted device 10 (step S11). This message information on the end of distribution is for prompting the user to area out, and the vehicle-mounted device 10 displays this message information. Thereafter, when communication with the roadside apparatus 20A or 20B is interrupted for a certain period of time, the control unit 4 of the vehicle-mounted device 10 determines that the distribution has ended and performs control to delete the uplink information (step S12). In response to this control, the DSRC control unit 3a deletes the uplink information in the uplink information storage area 3c1.

  As described above, the case where the vehicle-mounted device 10 acquires the parking lot dynamic information from the center device 30 via the roadside wireless device 20A or 20B using the DSRC unit 3 has been described. It is also possible to acquire the parking lot dynamic information from the center apparatus 30 via the wireless communication access point 20C using the unit 5 and the networks N2 and N3.

Next, a parking lot information storage process executed when the on-vehicle device 10 receives parking lot dynamic information will be described.
FIG. 10 shows a flowchart of the parking lot information storing process.
10 is executed by the control unit 4 in cooperation with the car navigation control unit 1a and each unit in the car navigation unit 1.

  When the control unit 4 receives the parking lot dynamic information by the DSRC unit 3 or the IP communication unit 5 (step S21), each parking lot ID included in the received parking lot dynamic information (for example, in the parking lot dynamic information) Alternatively, the reference number is assigned to the ID of the content information = the parking lot ID of the parking lot 1 within 50), and the reference number (reference reference number) n referred to in this processing is set to 1 (step S22).

  And the control part 4 discriminate | determines whether the static information corresponding to the parking lot ID to which the reference reference number n was attached | subjected exists in parking lot DB (step S23), and the reference reference number n was attached | subjected. When the static information corresponding to the parking lot ID is in the parking lot DB (step S23; Yes), the storage unit 1f stores the dynamic information of the parking lot indicated by the parking lot ID with the reference reference number n. (Step S24), it is determined whether or not the reference reference number n matches the total number of parking lot IDs included in the received parking lot dynamic information, that is, the number N of parking lot full / vacant information (Step S25).

  When the reference reference number n matches the parking lot full information number N (step S25; Yes), the control unit 4 ends this processing, and the reference reference number n does not match the parking lot full information N. (Step S25; No), 1 is added to the reference reference number n (Step S26), and the process returns to Step S23.

  When there is no static information in the parking lot DB corresponding to the parking lot ID assigned the reference reference number n in the parking lot DB (step S23; No), the control unit 4 generates a screen indicating that there is no static information, and A screen is displayed on the display unit 1e, and an instruction as to whether or not to acquire static information is received by the input unit 1d. And it is discriminate | determined whether there exists an instruction | indication which acquires static information by the input part 1d (step S27).

  When there is an instruction to acquire static information (step S27; Yes), the control unit 4 uses the DSRC unit 3 or the IP communication unit 5 to transmit uplink information including the information update request information and the latest information form flag. To device 30. The center device 30 transmits content information including static information of a parking lot that matches the specified condition to the vehicle-mounted device 10. The control unit 4 updates the static information stored in the parking lot DB to the received static information (step S28), and displays the dynamic information of the parking lot indicated by the parking lot ID with the reference reference number n. The data is stored in the storage unit 1f (step S29), and the process proceeds to step S26.

  When there is no instruction to acquire static information (step S27; No), the control unit 4 discards the dynamic information of the parking lot indicated by the parking lot ID with the reference reference number n (step S30), Proceed to step S26.

  In this way, it is possible to save only the dynamic information of the parking lot whose static information is stored in the parking lot DB, that is, only the dynamic information of the parking lot whose location is clear.

Next, the parking lot information display process performed after completion of the parking lot information storage process in the vehicle-mounted device 10 will be described.
In FIG. 11, the flowchart of the parking lot information display process in this 1st Embodiment is shown.
The processing shown in FIG. 11 is executed by the control unit 4 in cooperation with the car navigation control unit 1a and each unit in the car navigation unit 1, but the car navigation control unit 1a cooperates with each unit in the car navigation unit 1. May be executed.

  The control unit 4 determines whether or not the search position information indicating the search location included in the uplink information is the position of the vehicle C when the uplink information is transmitted (at the time of the search request) (step S41). .

  When the search position information indicating the search location is not the position of the vehicle C at the time of the search request (step S41; No), the control unit 4 shows the map screen on which the search position information indicating the search location is currently displayed on the display unit 1e. It is determined whether or not it is included in the area on the map information (step S42).

  When the search position information indicating the search location is not included in the area indicated by the map screen currently displayed on the display unit 1e (step S42; No), the control unit 4 displays the area including the search position information. Is generated and displayed on the display unit 1e (step S43).

  When the search position information indicating the search location is the position of the vehicle C at the time of the search request (step S41; Yes), the control unit 4 displays the search position information in the area indicated by the map screen currently displayed on the display unit 1e. If it is included (step S42; Yes), or after step S43, that is, after the map screen showing the area including the search position information is displayed on the display unit 1e, all saved in the parking lot information saving process Each of the static information in the parking lot DB corresponding to the parking lot ID of the parking lot dynamic information of the parking lot is referred to, and all the maps saved in the parking lot information saving process are displayed in the currently displayed map screen area. It is determined whether or not the location information of the parking lot is included (step S44).

  When the area of the currently displayed map screen does not include the position information of all the parking lots saved in the parking lot information saving process (step S44; No), the control unit 4 displays the currently displayed map. The scale is changed to an area including the location information of all parking lots where the area of the screen is stored, and the scale-changed map screen is displayed on the display unit 1e (step S45).

The control unit 4 sets the area of the map screen currently being displayed as an area for displaying the parking status mark (step S46). Then, referring to each static information in the parking lot DB corresponding to the parking lot ID of the dynamic information of each parking lot saved in the parking lot information saving process, the static information of the parking lot including the same representative coordinates is referred to. It is determined whether there is target information, that is, whether there is a parking lot constituting a composite parking lot among a plurality of stored parking lots (step S47).

The control unit 4, if there is no static information including the same representative coordinates to each other, i.e., all of the parking lot saved, if not the parking lot of the composite Parking (step S47; No), the representative coordinates It is determined whether there is any static information on the parking lot that matches the coordinates indicated by the entrance information (step S48).

The control unit 4, if the coordinates indicating the representative coordinates and entrance data there is no static information parking is match, i.e., all of the representative coordinates of each parking lot to save the dynamic information in the parking lot information storing process If the coordinates indicated by each entrance information do not match (step S48; Yes), a parking status mark having a different size and / or color depending on the fullness information included in the dynamic information of each parking lot is displayed on each parking lot. It displays on the position in the map screen according to the coordinate which each entrance information shows (step S49), and complete | finishes this process.

The control unit 4, if there is static information parking lot and coordinates indicating the representative coordinates and inlet information matches, that is, any one of the parking lot of the representative coordinates stored dynamic information at the parking lot information storing process If the coordinates indicated by the entrance information match (step S48; No), a parking status mark having a different size and / or color depending on the fullness information included in the dynamic information of each parking lot is designated as a representative of each parking lot. It is displayed at a position in the map screen according to the coordinates (step S50), and this process is terminated.
Even when there is no representative coordinate, a parking condition mark is displayed at the position indicated by the entrance information.

When there is static information of a parking lot including representative coordinates that match (identical) with the static information of other parking lots, the control unit 4, that is, among a plurality of parking lots saved in the parking lot information saving process When there is a parking lot constituting the composite parking lot (step S47; Yes), a parking lot information management table is generated (step S51).

First, the parking lot information management table in step S51 is generated by associating the dynamic information of each parking lot in which the dynamic information is stored in the parking lot information saving process with the static information of each parking lot. Is generated in the storage unit 1f. When this parking lot information management table is generated, a reference number is assigned to each record. The same flag is set for a record having static information whose representative coordinates coincide with other parking lots, that is, a record of a parking lot constituting a composite parking lot, and when the same flag is set, the representative flag is set. A parking lot ID of another parking lot having the same coordinates is added. (Step S51).

FIG. 12 shows an example of a parking lot information management table in the first embodiment.
As shown in FIG. 12, the parking lot information management table includes a reference number, a parking lot ID, vacancy information as dynamic information of a parking lot corresponding to the parking lot ID, and a parking lot corresponding to the parking lot ID. Records consisting of representative coordinates, entrance information (entrance coordinates) 1 to 15 as static information, vehicle restrictions, equipment status, business hours, and the same flag and the same parking lot ID are dynamically generated in the parking lot information storing process. It is composed of several minutes of parking lots that store information.

In the same flag, 1 is set when the representative coordinates have static information that coincides with other parking lots, that is, when it is a parking lot record constituting a composite parking lot.
Further, in the same parking lot ID, when the same flag is set to 1, parking lot IDs of other parking lots whose representative coordinates match are stored.

  After generating the parking lot information management table (after step S51), the control unit 4 sets a reference number (reference reference number) m indicating a record to be referred to in the generated parking lot information management table to 1 (step S52). .

  The control unit 4 determines whether or not the same flag is set to 1 for the record having the reference reference number m (step S53). If the same flag is not set to 1, that is, the same flag is 0. If there is one (step S53; No), the first parking status mark display process is executed (step S54). On the other hand, the control part 4 performs a 2nd parking condition mark display process, when the same flag is set to 1 in the record of the reference reference number m (step S53; Yes) (step S55).

  After step S54 or S55, the control unit 4 matches the reference reference number m with the total number M of records constituting the parking lot information management table, that is, the total number of parking lots where dynamic information is stored in the parking lot information storage process. (Step S56; No), 1 is added to the reference reference number m (Step S57), and the process returns to Step S53.

  When the reference reference number m coincides with the total number M of the records constituting the parking lot information management table, that is, the total number of parking lots in which the dynamic information is saved in the parking lot information saving process (step S56; Yes). ), A parking lot information display process is executed (step S58), and this process ends.

  FIG. 13 shows a flowchart of the first parking status mark display process executed in step S54.

The control unit 4, the entrance information of the representative coordinates and the record of the record of the reference docket number m is compared with the coordinates indicated, the coordinates indicating the representative coordinates and all entrance information to determine different or not (Step S61). That is, it is determined whether there is any entry information 1 to 15 that matches the representative coordinates.

When the representative coordinates of the record with the reference reference number m are different from the coordinates indicated by all the entrance information of the record (step S61; Yes), the control unit 4 determines the size and / or according to the availability information of the record. The parking status mark having a different color is displayed at a position in the map screen corresponding to the coordinates indicated by each entrance information (step S62), and the process is terminated.

When the representative coordinates of the record having the reference reference number m do not differ from the coordinates indicated by all the entrance information of the record (step S61; No), the control unit 4 determines the size and / or the size according to the full / vacancy information of the record. Alternatively, parking status marks having different colors are displayed at positions in the map screen corresponding to the representative coordinates (step S63), and this process is terminated.

  In FIG. 14, the flowchart of the 2nd parking condition mark display process performed in step S55 is shown. This process is a process of displaying a parking status mark of a parking lot that is determined as a parking lot that has the same flag set to 1 and that constitutes a composite parking lot.

The control unit 4 records the reference reference number m and the parking lot ID record indicated by the same parking lot ID of the record (a record having the reference reference number m and the representative coordinates match, hereinafter also referred to as a matching record). And whether or not representative coordinates are included in the entry information (entrance information 1 to 15) of each record, that is, whether or not each record includes coordinates indicated by the entry information that matches the representative coordinates. Is determined (step S71).

When the record of the reference reference number m and the matching record each include the coordinates indicated by the entry information that matches the representative coordinates (step S71; Yes), the control unit 4 fills up the record of the reference reference number m. It is determined whether or not the information is different from the full / empty information of the matching record (step S72).

When the empty information of the record with the reference reference number m is different from the empty information of the matching record (step S72; Yes), the control unit 4 determines the size and the size according to the empty information of the record with the reference reference number m. A parking situation mark with a different color and a parking situation mark with a different size and / or color depending on the fullness information of the matching record, the map corresponding to the same representative coordinates in each of these records on the surface The display is superimposed on the display position (step S73), and this process is terminated.

When the full information of the record with the reference reference number m is not different from the full information of the matching record, that is, when the same full information is obtained (step S72; No), the control unit 4 The parking status mark corresponding to the full information of the record and the full information of the matching record is displayed at the display position corresponding to the representative coordinate of the record of the reference reference number m on the map screen (step S74), and this processing is terminated. To do.

When the reference reference number m and the matching record do not have the coordinates indicated by the entry information that matches the representative coordinates (step S71; No), the control unit 4 determines the reference reference number m record and the matching record. to determine whether it has a coordinate showing the same entrance information with each other (step S75).

  When the record of the reference reference number m and the matching record have the coordinates indicated by the same entry information (step S75; Yes), the control unit 4 determines that the full information and the matching record of the record of the reference reference number m It is determined whether the full / vacant information is different (step S76).

  When the empty information of the record with the reference reference number m is different from the empty information of the matching record (step S76; Yes), the control unit 4 determines the size and / or the size according to the empty information of the record with the reference reference number m. Alternatively, a parking status mark having a different color and a parking status mark having a different size and / or color according to the full / vacant information of the matching record are placed at the same display position according to the coordinates indicated by the same entrance information on the map screen. The images are displayed in an overlapping manner (step S77), and this process is terminated.

  When the full information of the record with the reference reference number m is not different from the full information of the matching record, that is, when the same full information is obtained (step S76; No), the control unit 4 records the reference reference number m. The parking status mark corresponding to the full availability information and / or the full availability information of the matching record is displayed at the display position corresponding to the coordinates indicated by the same entrance information on the map screen (step S78), and this processing is terminated. .

  When the record of the reference reference number m and the matching record do not have the coordinates indicated by the same entry information (that is, the control unit 4 matches the coordinates indicated by the entry information of the record of the reference reference number m and the matching record). When the coordinates indicated by each entrance information are different) (step S75; No), the parking arrangement mark having a different size and / or color according to the fullness information of the record of the reference arrangement number m is referred to on the map screen. Matching records on the map screen are displayed on the map screen with parking status marks that differ in size and / or color according to the fullness information of the matching records. Is displayed at a display position corresponding to the coordinates indicated by each of the entrance information (step S79), and this process is terminated.

FIG. 15 shows an example of the parking status mark displayed on the map screen.
FIG. 15A shows a parking status mark (empty vehicle mark) P1 when the full / vacancy information is an empty vehicle. FIG. 15B shows a parking status mark (congestion mark) P2 when the full / vacancy information is congested. FIG. 15C shows a parking status mark (full mark) P3 when the fullness information is full.

  As shown in FIG. 15, the relationship between the sizes of the parking status marks P1, P2, and P3 is a relationship in which the size increases in the order of the empty vehicle mark P1, the congestion mark P2, and the full vehicle mark P3. The larger the number of cars, the larger the size of the parking situation mark, and the easier it is to visually grasp the congestion situation according to the number of parked cars. Moreover, the color relationship of each parking condition mark P1, P2, and P3 is a mutually different color. For example, the empty vehicle mark P1 is set to blue, the congestion mark P2 is set to orange, and the full vehicle mark P3 is set to red, so that the congestion situation corresponding to the number of parked vehicles can be easily distinguished visually.

FIG. 16 shows an example when the parking status mark is displayed at the same display position.
As shown in FIG. 16, when the parking status marks P1, P2, and P3 are displayed at the same display position corresponding to the same position information on the map screen, the plane is displayed when the map screen is displayed in a two-dimensional format. In a nested manner. This nesting state refers to a state in which a large object is incorporated in order from a small object. For example, when the relationship between the sizes of the parking status marks P1, P2, and P3 is a relationship in which the size increases in the order of the empty vehicle mark P1, the congestion mark P2, and the full vehicle mark P3, in other words, the innermost empty vehicle In this state, the mark P1, the middle congestion mark P2, and the outer full mark P3 are arranged so as to overlap each other at a concentric position centered on a predetermined position coordinate. In addition, when the map screen is displayed in a three-dimensional format, the parking status marks may be displayed in a state of being sequentially overlapped from the largest to the smallest.
Therefore, even when the parking status mark indicating the full availability information is displayed at the same position, the full availability information indicated by each parking status mark can be visually recognized.

  In FIG. 17, the flowchart of the parking lot information detailed display process in 1st Embodiment performed in step S58 is shown.

  First, FIG. 18 shows an example of a map screen displayed on the display unit 1e in step S54 or step S55. As shown in FIG. 18, on the map screen G1, various parking status marks A1 to A5 indicating full / vacant information of each parking lot are displayed at positions corresponding to the respective position information. As for the parking status marks A1 and A2, various parking status marks are two-dimensionally displayed in a nested manner.

  The control unit 4 determines whether or not any of the parking status marks displayed on the map screen G1 is pressed and selected, that is, detailed information on the parking lot corresponding to the selected parking status mark. It is determined whether or not there is a display request (step S81). If there is no display request for the detailed information of the parking lot (step S81; No), the process is terminated.

  When any one of the parking status marks displayed on the map screen G1 is pressed and selected, the control unit 4 displays the detailed information of the parking lot corresponding to the selected parking status mark. When there is a display request (step S81; Yes), a map screen including the detailed information of the selected parking lot is displayed (step S82), and this process is terminated.

In FIG. 19, the example of the map screen containing the detailed information of the parking lot displayed in step S82 is shown. A map screen G2 shown in FIG. 19 is an example of a map screen displayed when the parking condition mark A1 is selected. On this map screen G2, a list L1 of the detailed information of the parking lot corresponding to the selected parking status mark A1 is displayed. The list L1 displays detailed information such as the name of the parking lot according to the static information of the parking lot indicated by each parking lot ID corresponding to the selected parking status mark A1 and the fullness information according to the dynamic information. Has been.
In addition, each parking lot displayed in the list L1 can be selected, and information on the selected parking lot, for example, static information such as the number of accommodated vehicles, vehicle restrictions, business hours, facility conditions, payment means, etc. is displayed. Also good.
