  FIG. 4 shows communication and processing between the devices performed in the transaction between the roadside device 15 and the ITS vehicle-mounted device 17. The roadside machine 11 and the server 12 constitute a roadside apparatus 15. The ITS vehicle-mounted device 17 includes a DSRC unit 18 and a navigation unit 19. Explain in chronological order. Communication between the roadside device 11 and the DSRC unit 18 is performed by DSRC radio waves, and communication between the roadside device 11 and the server 12 and between the DSRC unit 18 and the navigation unit 19 is normally performed wirelessly or by wire.

  As the ITS vehicle-mounted device 17 is turned on, client information data is written from the navigation unit 19 to the DSRC unit 18 in S10. In S11, the DSRC connection is established between the roadside device 11 and the DSRC unit 18 as the automobile 13 equipped with the ITS on-vehicle device 17 enters the radio wave arrival area at a distance (eg, about 30 m) where communication with the roadside device 11 is possible. Processing is performed.

  When the DSRC connection process in S11 is completed, a DSRC connection notification is made in S12 and S13. The connection notification in S12 is from the roadside device 11 to the server 12, and the connection notification in S13 is from the DSRC unit 18 to the navigation unit 19. In S <b> 14, client information is notified from the DSRC unit 18 to the server 12 via the roadside device 11.

  The server 12 reads the uniquely numbered onboard unit ID of the DSRC unit 18 to determine whether the user of the ITS onboard unit 17 is a member or a non-member, and based on client information notified from the DSRC unit 18 after communication is established. Then, the hardware information of the ITS in-vehicle device 17 for properly reproducing the content by the ITS on-vehicle device 17 is acquired. In S <b> 18, content such as a Welcom screen is transmitted from the server 12 to the navigation unit 19 via the roadside device 11 and the DSRC unit 18. The content is organized in a multi-content format. The navigation unit 19 determines a service provider from the multi-content format.

  After S18, the server 12 periodically polls the DSRC unit 18 in S19 until the navigation unit 19 writes the uplink information in the DSRC unit 18. In S20, the navigation unit 19 writes the uplink information to the DSRC unit 18 when the user of the ITS vehicle-mounted device 17 is determined to be a member of the service provider, but does nothing if it is not a member.

  In S <b> 24, the server 12 sends default content (e.g., public service information) to the navigation unit 19 via the roadside device 11 and the DSRC unit 18. In S <b> 29, the server 12 performs memory access polling for the DSRC unit 18. On the other hand, in S30, if the user is a member, the DSRC unit 18 notifies the server 12 of uplink information.

  In S33, the server 12 organizes the storage-type content suitable for the member preference based on the member information acquired from the uplink information in the multi-content format (FIG. 2) and distributes it to the ITS in-vehicle device 17. In S34, the end of distribution of the storage type content is notified. The automobile 13 equipped with the ITS vehicle-mounted device 17 leaves the communication area with the roadside device 11 with the end of distribution.

  FIG. 5 is a schematic diagram of data outline of uplink information sent from the ITS vehicle-mounted device 17 to the roadside device 15. Uplink information is sent in multiple tags. The tag 1 includes a service provider code, a destination (latitude and longitude), a waypoint (latitude and longitude) 1 to 5, a cumulative travel distance, a preference genre data version, preference genre data, and member information 1 to 8. The tag 2 includes a service provider code and past stopover locations (latitude and longitude) 1 to 41. The tag 3 includes a service provider code and past stopover places (latitude and longitude) 42 to 82.

  The tag 4 includes a service provider code and reception / reproduction history (reception information code and reproduction identification flag) 1 to 123. The tag 5 includes a service provider code and reception / reproduction history (reception information code and reproduction identification flag) 124 to 246.

  FIG. 6 shows an example of a preference data table distributed from the roadside device 15 to the ITS vehicle-mounted device 17. The preference data table is based on the creation of a service provider that manages the roadside device 15, and is transmitted from the roadside device 15 to the ITS in-vehicle device 17 in S18 of FIG. There are a total of 128 items in the preference data table, data numbers = 0 to 127, and there are display text, display nests, target identifiers, item values, etc. in association with the data numbers. Nest for display = 0 means the top layer, and the lower layer as the numerical value increases. The target identifier is a flag indicating whether or not each item of the data number is a target of preference registration by the user. As can be seen from FIG. It means that each user is a target of non-target registration for preference. The default values = 0 and 1 mean that the user has no preference and a preference for the item, respectively. In FIG. 6, all display items have a default value = 0.

  FIG. 7 is a preference data table generated in the ITS vehicle-mounted device 17 based on the preference data table of FIG. As can be seen from the comparison with FIG. 6, the smaller the display nest value, the smaller the classification. Further, only the display text in which the target identifier = 1 is the target of preference registration by the user as preference data. In FIG. 6, the default value = 0 for both “foreign film” and “Japanese film”, whereas in FIG. 7, the ITS in-vehicle device 17 possesses the ITS in-vehicle device 17 in order to reduce user input. This indicates that the default value for “foreign film” has been changed to 1 based on the data.

  Here, for each item of the preference data table, the value given to the roadside device 15 and sent to the ITS on-board device 17 is called a default value. On the other hand, the ITS on-board device 17 changes, A value presented to the user will be referred to as an item value. In FIG. 7, the user registers the presence / absence of preference only for the item at the lowest level, but if the target identifier = 1 is added to the item at the higher level, the user is classified into a large classification. The presence / absence of preference can also be registered for the middle category items.

  FIG. 8 is a block diagram of the vehicle-mounted device 50. The on-vehicle device 50 transmits the presence / absence of user's preference for each item of the preference data table to the roadside device as user preference information for the preference data table received from the roadside device in the wireless communication area of the roadside device. A specific example of the vehicle-mounted device 50 is the ITS vehicle-mounted device 17. The in-vehicle device 50 is not limited to a device that transmits and receives data by DSRC. It may correspond to other communication standards and data formats. The vehicle-mounted device 50 includes item search means 51 and item value provision means 52.

  The item search means 51 searches for a revised or new item in the revised preference data table or the new preference data table. The item value assigning means 52 includes (a) an item hierarchy relationship including the predetermined item in the old version or another preference data table, and (b) an identifier of the predetermined item for the predetermined item in the revised or new item. User preference information about items in the old version or another preference data table that matches, (c) relevance to the stop-by place, or (d) the user is associated with a keyword registered in advance. An item value is assigned to the keyword dictionary based on the coincidence between the phrase and the text of the predetermined item. That is, the item value assigning means 52 assigns an item value for an item related to the predetermined item for the predetermined item.

  The preference data table is sent from the roadside device to the vehicle-mounted device 50 together with the version information (ID = 80). Therefore, the item search means 51 can determine whether or not the preference data table has been revised based on the version information. The preference data table is sent from the roadside device to the vehicle-mounted device 50 together with the code information (ID = 01) of the service provider. Therefore, the item search means 51 may determine that the received preference data table is a new preference data table unless the preference data table associated with the code information of the service provider has been received in the past. it can.

  A specific example of (a) will be described in relation to the following FIGS. A specific example of (b) will be described with reference to FIGS. A specific example of (c) will be described with reference to FIGS. A specific example of (d) will be described with reference to FIGS.

  First, a specific example of (a) will be described. In these examples, the item value assigning means 52 generates a consistency condition including the item hierarchy relation extracted based on the display nesting and display text of each item in the old version or another preference data table, and revised or new If the display nest and the display text in the revised preference data table or the new preference data table for the item satisfy the matching condition, the revised or new item is set as a predetermined item. Then, the item value giving means 52 sets the item value for the predetermined item to a value related to the user preference information for the corresponding item in the old version or another preference data table that is the basis for generating the consistency condition.

  FIG. 9 shows user preference information in a preference data table of a car dealer who has been registered by the user in the past. In FIG. 9, “Auto Fronts” is assumed to be the name of a car dealer. In FIG. 9, the user has checked that there is a preference for “tire replacement”, “AV device”, and “Navi”. The ITS vehicle-mounted device 17 stores data of user preference information attached to each preference data table by the user.

  FIG. 10 shows an example in which the ITS vehicle-mounted device 17 automatically assigns an item value with preference to predetermined preference data based on the preference data of FIG. 9 with respect to the new preference data table received from the roadside device 15. In FIG. 10, “Green Huts” is assumed to be the name of a car dealer. “Auto Fronts” in FIG. 9 and “Green Huts” in FIG. 10 are different companies in the same industry.

  The ITS vehicle-mounted device 17 automatically assigns an item value with preference to the item “tire replacement” indicated by → in FIG. 10 to the new preference data table. Therefore, the user is saved the trouble of checking the item “tire replacement”. That is, if there is an item of display text that is the same as the display text in the previously registered preference data table in the new preference data table, the ITS on-vehicle device 17 sets the item value of the item as the item of the previously registered preference data table. Set the same value. In FIG. 10, the item “wiper” is checked, which is checked by the user himself / herself.

In the example of FIG. 11 and FIG. 12 , when the matching condition is satisfied, the display text of the item whose hierarchy is higher and the display text of the item of the lower hierarchy in the old version or another preference data table However, in the revised preference data table or the new preference data table, the case where the hierarchy matches the display text of the lower item and the display text of the upper item is included.

  FIG. 11 shows user preference information in a preference data table of a DVD rental company that the user has registered in the past. In FIG. 11, “DVD rental 1” is assumed to be the name of a DVD rental company. There are layers such as “SF” and “Action” under the “Western” layer, and they are checked. The ITS in-vehicle device 17 generates a conditional expression for automatic item value assignment from the user preference information. Here, there are a total of two conditional expressions, 1 and 2. Conditional expression 1 is [foreign film] AND [SF], and conditional expression 2 is [foreign film] AND [action]. In other words, this is a conditional expression of the logical product of the text for the item in the upper hierarchy and the text of the item belonging to the lower hierarchy.

  FIG. 12 shows an example in which the ITS vehicle-mounted device 17 automatically assigns item values to predetermined preference data based on the preference data of FIG. 11 for the new preference data table received from the roadside device 15. In FIG. 11, “DVD rental 2” is assumed to be the name of a DVD rental company. In the preference data table of FIG. 12, there is an item “foreign film” in the hierarchy below the hierarchy of the item “SF”. In addition, there is an item “foreign film” in a hierarchy below the hierarchy of the item “action”. Although this hierarchical relationship is opposite to that in FIG. 11, since the conditional expressions 1 and 2 extracted from FIG. 11 are satisfied, the two “foreign pictures” in FIG. 12 have the preference of FIG. 11 that is the basis of the conditional expression. An item value is assigned to a value related to user preference information for an item in the data table.

In the specific examples of FIGS. 13 and 14 , the item value assigning means 52 is an item in which the display text in the old version or another preference data table is the same as the display text in the revised preference data table or the new preference data table. On the other hand, in the old version or another preference data table, there are a plurality of items below the item, and items with and without preference are mixed. In the revised preference data table or the new preference data table, When there is no non-preferred item in the lower hierarchy, the item value of the item in the revised preference data table or the new preference data table is set as preferred.

  FIG. 13 shows user preference information of a preference data table on which another conditional expression is extracted. In the preference data table of FIG. 13, there are “foreign” and “Japanese” layers below the “action” layer, which are checked and not checked, respectively. The ITS vehicle-mounted device 17 generates affirmative and negative conditional expressions for automatic item value assignment from the user preference information. Here, the positive conditional expression is [action] OR [foreign film], and the negative conditional expression is a conditional expression for searching for a negative phrase, [action] NOT [Japanese film]. In other words, in the affirmative conditional expression, items in the hierarchy above the checked item are combined with OR, whereas in the negative conditional expression, the item in the hierarchy above the item not checked is NOT. Join.

  FIG. 14 shows an example in which the ITS vehicle-mounted device 17 automatically assigns item values to predetermined preference data based on the preference data of FIG. 13 for the new preference data table received from the roadside device 15. In the preference data table of FIG. 14, there is an “action”, which satisfies the positive conditional expression, but does not satisfy the negative conditional expression. That is, negative words are not included. Therefore, according to the affirmative conditional expression, “Action” in the preference data table of FIG. 14 is checked.

  In the specific examples of FIGS. 15 and 16 below, the item value giving means 52 is an item in which the display text in the old version or another preference data table is the same as the display text in the revised preference data table or the new preference data table. On the other hand, if there are no items below the item in the old version or another preference data table, and items below the item exist in the revised preference data table or the new preference data table, those items below The item value for the item in the hierarchy is set to a value related to the user preference information for the item in the old version or another preference data table.

  FIG. 15 shows user preference information of a preference data table that is used as a basis when item values are automatically assigned by another method. In the preference data table of FIG. 15, “Action” in the hierarchy below “Western film” is checked, while the action in the hierarchy below “Japanese film” is not checked. In contrast, conditional expression 3 generates [foreign film] AND [action], and conditional expression 4 generates [Japanese film] AND [action].

  FIG. 16 shows an example in which the ITS vehicle-mounted device 17 automatically assigns item values to predetermined preference data based on the user preference information of FIG. 15 for the new preference data table received from the roadside device 15. In the preference data table of FIG. 16, there are items “Starring A” and “Starring B” in the lower layer of “Action” of “Western movie”, and item “Starring of the layer in the lower layer of“ Action ”of“ Japanese movie ”. U "and Starring V. In the case of Starring A" and "Starring B", "Action" and "Western film" in the hierarchy above are in agreement with the condition of conditional expression 3. Since U "and starring V" match the condition of conditional expression 4, the item values of "Starring A", "Starring B", "Starring U" and Starring V "are set as the corresponding" Action "in FIG. It is assumed that the user preference information is inherited.

  Next, a specific example of the above (b) will be described. FIG. 17 is a code table when a common code is set between service providers for predetermined items in the preference data table.

Then, the ITS in-vehicle device 17 selects, as preference data, a phrase that is used as the display text in the preference data table in relation to each selected supplier.

  If there is a display text item that is the same as the selected word in FIG. 21 for the new preference data table, the ITS on-vehicle device 17 checks the item. The user preference information for the new preference data table is transmitted to the roadside device 15, and the content corresponding to the user preference information is distributed from the roadside device 15 to the ITS in-vehicle device 17. In FIG. 20, the final stop time is recorded for each stop point. This is because the user stores the stored content (stored in a storage device without being played immediately after reception) and with the call from the user. If the content to be reproduced such as display is not reproduced for a predetermined time or more from the last stop time, the selected phrase related to the content is deleted from the table of FIG. 21, thereby improving the accuracy of the user preference information. Because.

  Instead of the stop point in FIG. 20, a point set by the user as a landmark (convenience store, gas station, etc.) in the navigation unit 19 may be used. In this case, the number of stoppages is not measured, and products and services related to the landmark are simply associated.

  Next, how to set item values in the new preference data table using the keyword dictionary will be described. The keyword dictionary is as follows. Movies (foreign movies (action, suspense, drama, science fiction, Asia, comedy, love story, fantasy, horror, war, classic, documentary), Japanese film (action, suspense, drama, science fiction, comedy, love story, special effects hero, horror) , Anime (Kids, Family, Original, SF, Action, Robot, Comic, Overseas, Sports), Variety (Comedy, Animal, Family, Culture, Variety, Idol, Making, Gambling)},

  In the keyword dictionary, a large-class movie {} includes a medium-class movie (), a Japanese film (), an animation (), and a variety (). Suspense, ... is included.

  Finally, a specific example of (d) will be described. FIG. 22 is a keyword selection screen that allows the user to set in advance before automatic setting of item values in the preference data table in the ITS in-vehicle device 17. It is assumed that the user has checked “Movie” on the selection screen. The ITS vehicle-mounted device 17 refers to the item “movie” in the keyword dictionary described above for this check. Then, in the item value automatic setting for the new preference data table, the consistency between the display text of each item in the new preference data table and the phrase belonging to the category of “movie” in the keyword dictionary is checked, and the matched new preference data table Automatically check items. FIG. 23 shows user preference information in a new preference data table with item values assigned based on the keyword dictionary.

  FIG. 24 is a flowchart of the vehicle-mounted device control method 60. The onboard equipment control method 60 is applied to the onboard equipment 50 (FIG. 8). In S61, a revised or new item is searched for the revised preference data table or the new preference data table. In S62, for a predetermined item in the revised or new item, an item hierarchy relationship including the predetermined item in the old version or another preference data table, an old version or another preference data table in which the identifier matches the identifier of the predetermined item Based on the user preference information for the item, the relevance to the stop-by location, or the match between the phrase and the text of the predetermined item in the keyword dictionary associated with the keyword that the user has registered in advance. Assign item value. That is, an item value for an item related to the predetermined item is assigned to the predetermined item.
