The navigation system 810 can acquire the current position data of the vehicle by using a position data acquisition unit 811 that receives a GPS signal from a GPS satellite and calculates its own position coordinate data. In the information providing system of the present invention, the navigation system database 820 stores road information, facility information, and the like. As for facility information, it is necessary to provide the type of facility information (separately for restaurants, public facilities, etc.), and for road information, provide road type information (general roads, expressways, etc.). It is preferable. The road data managed by the map database 820 for the navigation system is managed by the concept of nodes and links. Conventionally known concepts of such nodes and links can be used.

The navigation system 810 in the navigation system unit 800 has a function of searching for a route and registering a route selected by the driver among the searched routes as scheduled route data. In order to realize such a function, a conventionally well-known technique can be used. In addition, the navigation system unit 800 can correct the route searched by itself based on a special rule transmitted from the server device on the center side.

  Next, a server device provided on the center side will be described. FIG. 3 is a diagram showing an outline of the center-side server device in the information providing system according to the embodiment of the present invention. In the configuration of the server device (information providing system) on the center side in FIG. 3, reference numeral 1100 denotes an arithmetic processing unit, 1110 denotes a facility-related special rule database, and 1120 denotes a communication unit.

  The arithmetic processing unit 1100 in the server device is an information processing mechanism that includes a CPU, a storage device, an interface device, and the like, and a conventionally known one can be used. The arithmetic processing unit 1100 cooperates and operates with each component connected to the illustrated arithmetic processing unit 1100. The arithmetic processing unit 1100 executes various control processes in the traffic jam situation estimation system of the present embodiment based on programs and data stored in a storage unit such as a ROM in the processing computer 300.

  The facility-related special rule database 1110 in the server device (information providing system) is a database that stores data collected from the vehicle 10 that is a probe car, and is appropriately updated with the data collected from the vehicle 10. In addition, the facility-related special rule database 1110 allows the server device to extract special rules from the actual travel route of each vehicle 10 and the pattern in which special rules occur (whether they occur on weekdays or on holidays) And is used as an original database for calculating the frequency of the vehicle 10 traveling according to a special rule. Here, the facility-related special rules are rules different from general traffic rules established in relation to a predetermined facility. When entering or leaving the facility, Applies to running.

  The communication unit 1120 is a wireless communication device that can transmit and receive data to and from the vehicle 10, and the server device (information providing system) on the center side can then transmit the planned route of the vehicle 10 from the information providing system (shown in FIG. 2). Data and actual travel data can be collected, and special rules extracted on the server side can be distributed to each vehicle 10 side.

  A process flow in the information providing system configured as described above will be described. FIG. 4 is a diagram showing a processing flow of the in-vehicle side system and the center side server device in the information providing system according to the embodiment of the present invention. In the example shown in FIG. 4, the center side server device is explained as communicating with one in-vehicle system. The same communication is performed.

  In step S100, when processing in the information providing system (on-vehicle side system) is started with the start of the vehicle 10 or the like, in step S101, the destination related to the predetermined facility is already set in the navigation system unit 800. It is determined whether or not. When the determination in step S101 is YES, the process proceeds to step S102, and the scheduled route data set by the navigation system unit 800 is transmitted to the center server side. Information from the vehicle 10 in which the planned route data is set in this way is used for the center server side to extract a special rule. On the other hand, if the determination in step S101 is no, skip to step S102 and proceed to step S103. On the center server side, information from a vehicle for which planned route data is not set is handled as general probe data.

  On the in-vehicle side system side of the vehicle 10, the current position data is acquired by the position data acquisition unit 811 in step S 103, and the transmission of the current position data to the center server side is repeated in step S 104 until the vehicle finishes running. Continue to send 10 actual travel route data to the center server. Therefore, in step S105, it is determined whether or not the vehicle 10 has finished traveling. When the determination is NO, the process proceeds to step S106, and after waiting for a predetermined time (or predetermined distance), the step is performed. Return to S103 and loop. On the other hand, when the determination is YES, the process proceeds to step S107, and information indicating that the traveling is finished is transmitted to the center server side. In step S108, the processing on the in-vehicle side system side of the vehicle 10 ends.

  On the other hand, when the process on the center server side is started in step S200, the planned route data set in the navigation system unit 800 of the vehicle 10 is received from the in-vehicle side system side of the vehicle 10 in step S201. It is determined whether or not. When the determination in step S201 is YES, the process proceeds to step S202, and a process for mapping the planned route data of the vehicle 10 is executed. On the other hand, when the determination in step S202 is NO, step S201 is skipped and processing for obtaining normal probe data from the vehicle 10 is executed.

  When the center server side receives the current position data of the vehicle 10 in step S203, the center server side constructs actual travel route data by mapping the current position data in step S204. This actual travel route data is performed until the travel of the vehicle 10 is completed.

  In step S205, the actual travel route data and the planned route data are compared (when the planned route data exists), and it is determined whether or not they are different in step S206. If the determination in step S206 is no, the process proceeds to step 209. If the determination is yes, the process proceeds to step S207.

In step S207, it is determined whether it is within a predetermined distance from the facility that is the destination set in the scheduled route data. If the determination in step S207 is no, the process proceeds to step 209. If the determination is yes, the process proceeds to step S208. In step S208, the scheduled route data and the actual travel route data different from this in the vicinity of the facility are registered in the facility-related special rule database 1110 together with calendar data (day of week / holiday data). Here, the facility-related special rule database 1110 will be described. FIG. 5 is a view for explaining the data structure of the facility-related special rule database 1110 in the traffic jam situation estimation system according to the embodiment of the present invention. The facility-related special rule database 1110 includes, for example, “facility name”, “by entry / exit”, “by holiday / holiday”, “planned route”, “actual travel route”, “frequency”, “ Adopted / Non-adopted ''
The data of each item is stored.

The “facility name” in the facility-related special rule database 1110 is an item that stores the name of a facility (or may be a position coordinate or the like) for which a special rule is determined. Also,
“Distinction at entry / exit” is an item for storing a distinction as to whether it is a special rule for entering the relevant facility or a special rule for exiting from the relevant facility.

  Further, “by holiday / holiday” is an item for storing a day of the week pattern to which a special rule is applied. In this item, for example, it is stored whether the special rule is applied to all including weekdays, or whether the special rule is applied only to holidays and holidays.

Further, “planned route” in the facility-related special rule database 1110 is an item for storing planned route data acquired from the vehicle 10, and “actual travel route” is an item for storing actual travel route data acquired from the vehicle 10. . By analyzing the difference between planned route data and actual travel route data obtained from these two items, it is possible to grasp what the special rules are (for example, right turn prohibition etc.) it can. In the “frequency” item, the percentage of vehicles that have traveled is stored in accordance with a special rule. In addition, based on the “frequency” item, whether it is adopted or not adopted is determined as a special rule, and whether it is adopted or not adopted is stored in the item “adopted / not adopted”.

  Returning to the flowchart of FIG. 4, in step S <b> 209, it is determined whether traveling end information is received from the in-vehicle side system. When the determination in step S209 is NO, the process returns to step S203 and loops. On the other hand, when the determination is YES, the process proceeds to step S210, and the process ends.

Next, in the facility-related special rule database 1110, processing for determining whether to adopt or not to adopt a special rule based on the item “frequency” will be described. Such processing is periodically performed in order to keep the facility-related special rule database 1110 in a state where the latest information is reflected. FIG. 6 is a diagram showing an example of data update processing in such a facility-related special rule database 1110. When the process is started in step S300, registration data ("frequency" data) of the facility-related special rule database 1110 is acquired in the subsequent step S301. In step S302, it is determined whether or not special rule driving occurs at a frequency equal to or higher than a predetermined value. When the determination result is YES, in step S303, the facility-related special rule is adopted, and the item “adopted / not adopted” is selected. “Recruit” is written in “No”, and if this determination result is NO, in Step S304, the facility-related special rule is not adopted, and “Not adopted” is written in the item “Recruit / Not adopted”. Step S3
At 05, the process ends. In step S302, it is determined that the special rule travel occurs at a frequency equal to or higher than a predetermined value. As another method, for example, the first travel route of a specific user and the second and subsequent times are performed. It may be determined that the special rule traveling has occurred by comparing the traveling routes and examining the difference between the first traveling route and the second and subsequent traveling routes.

  Next, processing for distributing the information in the facility-related special rule database 1110 constructed on the center server side as described above to each vehicle 10 and providing the information to the driver in each vehicle 10 will be described with reference to FIG. . FIG. 7 is a diagram showing an information provision processing flow in the in-vehicle side system of the information provision system according to the embodiment of the present invention.

  In FIG. 7, when the information providing process in the in-vehicle system is started in step S400, the process proceeds to step S401, and the facility-related special rules distributed from the center side are received. In step S402, the distributed facility-related special rules are referred to, and it is determined whether or not a special rule exists in the destination facility set in the navigation system unit 800 of the vehicle 10. When the determination result of step S402 is YES, the process proceeds to step S403, and when it is NO, the process proceeds to step S405.

In step S403, a normal route search is performed based on the navigation system 810, and in step S404, the searched route is corrected with the facility-related traffic rules received from the center server side. On the other hand, in step S405, a normal route search is executed based on the navigation system 810. In step S406, the route search result is provided by the display 610 or the speaker 630, and the process ends in step S407. In step S404, it has been described that the search route is corrected by the facility-related traffic rule received from the center server side. However, when it is determined that the facility-related traffic rule exists, the route before and after the start is determined. It is also possible to create a route to a predetermined facility by connecting the route of the facility-related traffic rule to the end of this route. By doing so, it is possible to create a route by applying the facility-related traffic rules as in step S404.

  A case will be described in which the searched route is corrected by the facility-related traffic rule received from the center server side in step S404, and this is provided as an example of providing information in step S406. FIG. 8 shows an example of information provision in the in-vehicle side system of the information provision system according to the embodiment of the present invention. In FIG. 8, a facility “○ × Department Store” is set as a destination. When entering this facility, the existence of a special rule that prohibits a right turn across the oncoming lane is indicated by the facility-related special rule database 1110. An example is shown in which the route is corrected by the navigation unit 800 on the vehicle-mounted side based on this special rule.

  FIG. 8 is a screen display example on the display 610 of the interface unit 600. As shown in FIG. 8, for example, on the display 610, the special rule for entering “Ox department store” as (center information) is “There is a possibility that you cannot make a right turn due to the special rule. It will be easier for the driver to understand the special rules. At the same time, it is preferable to propose an alternative route shown in FIG. In addition, the above description can be transmitted to the driver by voice through the speaker 630.

  As described above, according to the information providing system according to the present invention, data is acquired from a probe car (vehicle), a facility-related special rule is extracted from this, and the extracted facility-related special rule is stored on each in-vehicle device side. Because it is provided, the driver can make information on special rules related to the facility in advance, and it is not necessary to make an unintended detour or make a U-turn, so the driving risk can be suppressed, This eliminates wasted time.
