Information on a plurality of events can be recorded for a single facility or region, and a plurality of holding periods can be recorded for events held repeatedly.

The server program 21 includes a visited place acquisition unit 21a, an event acquisition unit 21b, and an event guide unit 21c.
The visited site acquisition unit 21a is a module that causes the control unit 20 to realize a function of acquiring a user's visited site. Specifically, when the visitor acquisition unit 21a searches for a planned route from the departure point specified by the user to the final destination, the control unit 20 uses the via destination and final destination on the planned route. And at least one of them is acquired as a visited place. Hereinafter, when the destination is simply described, it can mean both the destination and the final destination. In addition, a facility and a region can be designated as the destination. When a facility is designated as the destination, a scheduled route that passes through or ends at the facility is searched. In addition, when a region is designated as the destination, a planned travel route is searched through or at a representative point in the region (such as a center city or a point where an administrative office is located).

  The control unit 20 searches for a planned travel route of the vehicle by the function of the visited place acquisition unit 21a, and transmits route information 130b indicating the searched planned travel route to the vehicle. The control unit 20 acquires the route search request information received from the vehicle-mounted device 110 by the function of the visited site acquisition unit 21a, and acquires the departure point and the destination indicated by the route search request information. Then, the control unit 20 searches for a scheduled route by connecting road sections defined in the map information 30a using a known route search method. The route search request information indicates whether the departure point or destination is the vehicle user's home. In the single route search request information, at least a single departure point and a single final destination are specified, but a single or a plurality of via destinations may be specified. The final destination exists at the end point on the planned route, and the transit destination exists in the middle of the planned route.

  When the final destination searches for a scheduled travel route other than the home by the function of the visited location acquisition unit 21a, the control unit 20 acquires the via destination and final destination of the planned travel route as the visited location. Note that if there is no transit destination on the scheduled route, the control unit 20 acquires only the final destination as the visited location. When the controller 20 searches for a planned travel route by the function of the visited place acquisition unit 21a, the control unit 20 records the route information 30b indicating the planned travel route on the recording medium 30 and transmits the route information 30b to the vehicle-mounted device 110. Thereby, the onboard equipment 110 can perform route guidance based on the route information 30b (130b).

  The event acquisition unit 21b is a module that causes the control unit 20 to realize a function of acquiring event information for acquiring information on an event to be held in the future at a visited place. With the function of the event acquisition unit 21 b, the control unit 20 collects event information from a large number of computers on the Internet 200, thereby recording event information 30 c in the recording medium 30 in advance. And the control part 20 acquires the information about the event of the visited place of guidance from the event information 30c by the function of the event acquisition part 21b.

  The event guide unit 21c is a module that causes the control unit 20 to realize a function of guiding an on-vehicle device 110 serving as a guide unit for an event that will be held in the future at a visited site after the user leaves the visited site. In the present embodiment, that the vehicle is away from the visited place means that the user is away from the visited place. In addition, the control unit 20 transmits the event guidance information 130c indicating the guidance point where the event guidance is performed and the content of the event to be guided to the vehicle-mounted device 110, thereby being held in the future at the visited site. Event to be guided to the vehicle-mounted device 110.

  Specifically, the function of the event guide unit 21c allows the control unit 20 to install an event that will be held in the future as a guide unit when the user returns home after visiting the final destination. Guide the vessel 110. The control unit 20 determines that the planned route to be traveled after the completion of the travel of the planned travel route whose final destination is a point other than the home and when the user can be regarded as having returned to the home. The vehicle-mounted device 110 is guided to an event that will be held in the future at the destination designated at the time of the search, that is, the visited place. When the accessory power source of the vehicle (power source of the vehicle-mounted device 110) is turned off at a point within a predetermined determination distance (for example, 300 m) from the final destination, the control unit 20 assumes that the user has visited the final destination. judge.

  Further, the function of the event guide unit 21c allows the control unit 20 to search for a new scheduled route to the user's home after visiting the final destination and start the passage of the new scheduled route by the user. Then, let the information department guide the event that will be held in the future. That is, in this embodiment, when the user returns to his / her home, after the final destination is visited, a new scheduled route to the user's home is searched, and the new scheduled route is further passed. This is when the user starts. The control unit 20 switches the ACC power source from OFF to ON at a point within a predetermined distance from the final destination (other than the home) of the original scheduled travel route, and then sends route search request information specifying a new destination. When acquired from the vehicle-mounted device 110, a new scheduled route is searched. At this time, if the home is included in the new destination and the vehicle starts to pass the new scheduled route, the control unit 20 visits the destination that was the original scheduled route. Let them know about upcoming events on the ground. Hereinafter, a new scheduled travel route including a home at the destination is referred to as a return route, and the original planned travel route that was traveled before the return route is searched is referred to as a forward route. In addition, the visited place that was the final destination on the outbound route is referred to as the final visited location, and the visited location that was the transit destination on the outbound route is referred to as the transit visited location.

  2A to 2C are schematic diagrams of the outward path and the return path. 2A to 2C, the accessory power supply is OFF / ON at the final visited place DS on the outward route O (solid line), and the return route R (broken line) toward the home H is searched for at the final visited place DS. In the outbound route O, there are transit visit sites DK1 to DK3 in addition to the final visit site DS. The final visited place DS and the via-visit places DK1, DK2 indicated by white circles are facilities, and the via-visit place DK3 surrounded by a solid line is an area. The control unit 20 searches for the return route R and transmits route information 130b indicating the return route R to the vehicle-mounted device 110. At the same time, the control unit 20 sets the guide points PS and PK1 to PK3 on the return route R, and provides the event guide information 130c for guiding the event when the guide points PS and PK1 to PK3 are passed through the vehicle-mounted device 110. Send to. By setting the guide points PS and PK1 to PK3 on the return route R, it is possible to guide the event at least after the user starts to travel on the return route R.

  Due to the function of the event guide unit 21c, the control unit 20 guides the event to be held in the future at the visited place that passes when the user goes on the return route R to the guide unit when the visitor passes on the return route R. Let Specifically, the control unit 20 causes the guide unit to guide the user when the user is away from the visited site by a predetermined distance T when the visited site is a facility by the function of the event guiding unit 21c. In FIG. 2A, the return route R is a route in the opposite direction to the outbound route O, and all the visited sites DS, DK1 to DK3 on the outbound route O are passed on the return route R. The control unit 20 sets the guide points PS, PK1, and PK2 at a point that is a predetermined distance T away from the final visited place DS and the route visited places DK1 and DK2, which are facilities that pass on the return path R, on the home H side. Set. Then, in each of the guide points PS, PK1, and PK2, the event guide information 130c for performing the event guide ES, EK1, and EK2 of the event to be held in the future at the final visited place DS and the via visited places DK1 and DK2 is mounted on the vehicle. To the device 110. The guidance ES, EK1, and EK2 are to provide at least guidance on the content and duration of the event as well as the venue of the event to be held in the future.

  On the other hand, when the visited place is an area, the control section 20 causes the guide section to guide the user when the user leaves the area by the function of the event guide section 21c. The control unit 20 sets a guide point PK3 at a point where the vehicle exits on the return route R from the via-visit site DK3 that is an area that passes on the return route R. That is, the control unit 20 sets the guide point PK3 at the point on the home H side among the two points where the boundary line of the route visit place DK3 and the return path R intersect. Then, at the guidance point PK3, event guidance information 130c for performing guidance EK3 of an event to be held in the future at the route visit place DK3 is transmitted to the vehicle-mounted device 110.

  In addition, the function of the event guide unit 21c allows the control unit 20 to guide the event that will be held in the future at a visited place that does not pass when the return route R is passed to the guide unit when the user starts the return route R. Let In FIG. 2B, the return route R is not a route in the opposite direction along the outbound route O, and the via-visit sites DK1 to DK3 on the outbound route O are not passed on the return route R. The control unit 20 sets the guidance point PS for performing guidance EK1 to EK3 of events to be held in the future at the via-visit destinations DK1 to DK3 that do not pass on the return path R, as the point where the user starts to travel on the return path R. Here, the point where the user starts to travel on the return route R is a point where the user is away from the final visited site DS on the outbound route O, and is home for a predetermined distance T on the return route R from the final visited site DS which is a facility. It is a point away to the H side. Here, since the final visited place DS is a point that passes on the return route R, the control unit 20 sets the final visited place DS at a point away from the final visited place DS on the return route R by the predetermined distance T toward the home H side. A guide point PS is set for performing a guide ES for an event to be held in the future.

  As a result, guidance ES and EK1 to EK3 of events to be held in the future at all the visited sites DS and DK1 to DK3 are performed at the guidance point PS where the user is away from the final visited site DS. In addition, when the last visited place DS is an area, the control unit 20 acquires a point on the return route R where the user exits outside the area of the last visited place DS as a point where the user starts to pass the return route R. do it. In addition, the guidance order of guidance ES, EK1 to EK3 of a plurality of events at a single guidance point PS may be the order of visits on the outbound route O, or the order reverse to the order of visits. The order may be in the order of early or late.

(1-2) Configuration of the vehicle-mounted device:
The vehicle-mounted device 110 is mounted on the vehicle. The vehicle-mounted device 110 includes a control unit 120 including a CPU, RAM, ROM, and the like and a recording medium 130. The control unit 120 executes a program stored in the recording medium 130 or the ROM. In the present embodiment, the control unit 120 executes the in-vehicle device program 121 as one of the programs.

  In the recording medium 130, the map information 130a similar to the map information 30a of the server 10 is recorded. The recording medium 130 stores route information 130b similar to the route information 30b transmitted from the server 10 and recorded on the recording medium 30 of the server 10. Based on the route information 130b, the control unit 120 executes route guidance for the forward route O and the return route R as planned travel routes.

  Event guide information 130c is recorded on the recording medium 130. As described above, the event guidance information 130c is information generated by the server 10, and as shown in FIG. 2A, at the guidance points PS, PK1 to PK3, etc. on the return route R, the guidance destinations DS, guidance ES of DK1 to DK3, This is information for causing EK1 to EK3 to be performed. When the vehicle passes the guidance points PS, PK1 to PK3 based on the event guidance information 130c, the control unit 120 executes the guidance ES and EK1 to EK3 of the visited places DS and DK1 to DK3.

  The vehicle includes a GPS receiver 141, a vehicle speed sensor 142, a gyro sensor 143, a user I / F unit 144, and a communication unit 145. The GPS receiver 141 receives radio waves from GPS satellites and outputs a signal for calculating the current position of the vehicle to the controller 120 via an interface (not shown). The vehicle speed sensor 142 outputs a signal corresponding to the rotational speed of the wheels provided in the vehicle. The control unit 120 acquires this signal via an interface (not shown) and acquires the vehicle speed. The gyro sensor 143 detects angular acceleration in the horizontal plane of the vehicle and outputs a signal corresponding to the direction of the vehicle. The control unit 120 acquires this signal and acquires the traveling direction of the vehicle. The user I / F unit 144 is an interface unit for inputting user instructions and providing various kinds of information to the user. The user I / F unit 144 outputs sound such as a display unit or a speaker that also serves as an input unit including a touch panel display (not shown). Output section. The communication unit 145 is a circuit for the vehicle-mounted device 110 to communicate with the server 10.

The on-vehicle device program 121 includes a destination setting unit 121a and a guidance control unit 121b.
The destination setting unit 121a is a module that causes the control unit 120 to realize a function of setting a destination (routed destination, final destination) of a planned travel route. Specifically, the function of the destination setting unit 121a causes the control unit 120 to acquire a destination based on a user's operation on the user I / F unit 144 and send route search request information specifying the destination to the server 10. Send.

  The guidance control unit 121b is a module that causes the control unit 120 to realize a function of causing the user I / F unit 144 to guide an event to be held in the future at a visited site. With the function of the guidance control unit 121b, the control unit 120 causes the visited location DS, DK1 to be changed when the current position of the vehicle is within the error range (for example, 50 m) of the guidance points PS, PK1 to PK3 indicated by the event guidance information 130c. The user I / F unit 144 is made to perform guidance ES, EK1 to EK3 of DK3. For example, the control unit 120 may output voice messages of the guidance ES and EK1 to EK3 from the speaker of the user I / F unit 144, or may display the guidance ES and EK1 to EK3 on the display of the user I / F unit 144. You may display the character which described the contents of.

  In the embodiment described above, it is possible to guide events to be held in the future at the user's visited sites DS, DK1 to DK3. In particular, since an event is guided after the user leaves the visited areas DS, DK1 to DK3, an event to be held in the future after visiting the visited areas DS, DK1 to DK3 can be guided. Therefore, it is possible to consider whether or not to revisit the visited sites DS, DK1 to DK3 in consideration of an event to be held in the future, depending on the satisfaction level when the visited sites DS and DK1 to DK3 are actually visited.

  Here, the destinations (route destinations and final destinations) designated when searching for the outbound route O can be regarded as the destinations DS and DK1 to DK3 that the user intended to visit. Therefore, by acquiring the destination designated at the time of the search for the outbound route O as the visited sites DS, DK1 to DK3, whether or not to revisit the visited sites DS and DK1 to DK3 that were intentionally visited is determined as an event. Judgment can be made in consideration.

  After the visit to the final visit destination DS on the outbound route O, when the user returns to his home H, he / she visits the final visit location DS by guiding future events at the visit locations DS, DK1 to DK3. Later, events to be held in the future can be guided at the visited sites DS, DK1 to DK3. Accordingly, it is possible to examine whether or not to revisit each of the visited sites DS and DK1 to DK3 by looking back over the entire outbound route O in which traffic has been completed. When a new scheduled travel route (return route R) toward home H is searched, the user returns home to home H by guiding an event that will be held in the future at destinations DS and DK1 to DK3 of outbound route O. When it is possible to reliably determine that R has been reached, events to be held in the future can be guided at the destinations DS, DK1 to DK3 on the outbound route O.

  As shown in FIG. 2A, information on events ES, EK1 to EK3 to be held in the future at the visited sites DS and DK1 to DK3 when passing through the visited sites DS and DK1 to DK3 is performed. It is possible to consider whether or not to revisit the visited sites DS and DK1 to DK3 in a situation where it is easy to remember ~ DK3. In addition, as shown in FIG. 2A, by guiding the event when the user is away from the visited sites DS, DK1, DK2, which are facilities, by a predetermined distance T, the user is not separated from the facilities at the visited sites DS, DK1, DK2 to some extent. In the stage, it is possible to guide events to be held in the future at the visited sites DS, DK1, DK2. Therefore, it is possible to examine whether or not to revisit the visited sites DS, DK1, and DK2 in a situation where the visited sites DS, DK1, and DK2 are easily remembered. As shown in FIG. 2A, an event is guided when the user leaves the visited area DK3, and when the user leaves the area of the visited area DK3, the event is held in the area. Consider whether or not to revisit the area in consideration of the event.

  In addition, as shown in FIG. 2B, when the control unit 20 starts the passage of the return route R in the future destination DS, DK1 to DK3 that does not pass when the return route R passes, Let me guide you. In the case of not passing through the visited place on the return route R, it is possible to guide events that will be held in the future at the earliest possible stage when traveling on the return route R. That is, it is possible to examine whether or not to revisit the visited sites DS, DK1 to DK3 in a situation where the visited sites DS and DK1 to DK3 are easily remembered.

(2) Navigation system processing:
Next, the guidance point setting process which the server 10 as a navigation system performs is demonstrated. FIG. 3 is a flowchart of the guide point setting process. First, the control unit 20 searches for a scheduled travel route (outbound route O) by the function of the visited site acquisition unit 21a (step S100). The outbound route O is a scheduled travel route whose final destination is not the home H. When searching for the forward path O, the control unit 20 records the forward path O in the path information 30b. Next, the control unit 20 confirms that the accessory power supply of the vehicle is turned off at the final destination (final visited site DS) of the outbound route O by the function of the visited site acquiring unit 21a (step S105). In other words, the control unit 20 confirms that the user has visited the final visited site DS after the outbound route O has been passed when the accessory power supply is turned off at a point within the determination distance (for example, 300 m) from the final visited site DS. Check. Therefore, the vehicle-mounted device 110 may transmit information indicating the current position when turning off the accessory power source to the server 10.

  Next, the control unit 20 searches for a scheduled passage route (return route R) after the accessory power source is turned on by the function of the visited site acquisition unit 21a (step S110). Here, the return route R means a scheduled travel route in which the home H is a transit point or an end point starting from the last visited place DS of the outbound route O. When searching for the return route R, the control unit 20 records the return route R in the route information 30b.

  Next, by the function of the event guide unit 21c, the control unit 20 determines whether or not the visited place on the outbound route O is only the final visited place DS (step S115). That is, it is determined whether or not the outbound route O is a scheduled travel route in which only the final destination is specified and no via destination is specified. The route information 30b indicating the outward route O and the return route R is recorded in the recording medium 30, and the control unit 20 can determine whether or not the visited location of the outbound route O is only the final visited location DS based on the route information 30b. .

  Next, the control unit 20 determines whether or not there is a return place visited by the function of the event guide unit 21c (step S120). Here, the return place visit places are the visit places DS, DK1 to DK3 that pass on the return path R among the visit places DS and DK1 to DK3 designated in the outbound route O. As illustrated in FIGS. 2A to 2C, when the via-visit destinations DK1 and DK2 are facilities, the control unit 20 determines that the via-visit visited locations DK1 and DK2 are the same when the shortest distance from the location of the facility to the return route R is equal to or less than a threshold value. It is determined that it is a return destination. In addition, when the route visit place DK3 is a region, the control unit 20 determines that the route visit place DK3 is the return trip place when the return route R passes through the area of the route visit place DK3. Further, since the final visited place DS is the starting point of the return route R, it is always the return visit location.

  When it is determined that the visited place on the outbound route O is only the final visited place DS (step S115: Y), or when it is not determined that there is a return place visited (step S120: N), the event guide unit 21c By the function, the control unit 20 determines whether or not the final visited place DS on the outbound route O is a facility (step S125). When it is determined that the last visited place DS of the outbound route O is a facility (step S125: Y), the control unit 20 uses the function of the event guide unit 21c to return the route R away from the last visited place DS (facility) by a predetermined distance T. The upper point is set as a guide point PS for performing guidance ES, EK1 to EK3 of events to be held in the future at all the visited sites DS and DK1 to DK3 (step S130). As shown in FIG. 2B, when the final visited place DS on the outbound route O is a facility and none of the transit visited locations DK1 to DK3 on the outbound route O passes on the return route R, the control unit 20 starts from the final visited location DS. A guide point PS is set at a point on the return route R separated by a predetermined distance T. The event guide ES, EK1 to EK3 includes at least the content of the event and the period of the event.

  On the other hand, if it is not determined that the last visited place DS of the outbound route O is a facility (step S125: N), the points on the return route R leaving the last visited place DS are all visited places DS, DK1 to DK3. It is set as a guidance point PS for performing guidance ES, EK1 to EK3 of an event to be held in the future (step S135). When the visited place on the outbound route O is only the final visited place DS, all the visited places in step S130 indicate only the final visited place DS. Accordingly, when the outbound route O is a scheduled travel route in which only the final visited location DS is designated, in steps S130 and S135, a point on the return route R that is a predetermined distance T away from the final visited location DS or the final visited location. A point on the return route R leaving the ground DS is set as a guidance point PS for a guidance ES of an event to be held in the future at the final visited place DS.

  On the other hand, when it is determined that there is a return visit place (step S120: Y), the control unit 20 selects one of the return visit places as the target visit place by the function of the event guide unit 21c (step S140). . The target visited place means a return place visited that is a processing target.

  Next, by the function of the event guide unit 21c, the control unit 20 determines whether or not the target visited place is a facility (step S145). When it is not determined that the target visited place is a facility (step S145: N), the control unit 20 uses the function of the event guide unit 21c to set a point on the return route R to exit from the target visited place (region) as the target visited place. Is set as a guide point for an event to be held in the future (step S150). In FIG. 2A, when the route visit place DK3 is selected as the target visit place, the control unit 20 will hold an event in the future at the route visit place DK3 on the return route R leaving the area of the route visit place DK3. The guidance point EK3 for performing the guidance EK3 is set.

  On the other hand, when it is determined that the target visited place is a facility (step S145: Y), the function of the event guide unit 21c causes the control unit 20 to make a point on the return route R that is a predetermined distance T from the target visited place (facility). Is set as a guide point for an event to be held in the future at the target visited place (step S160). In FIG. 2A, when the route visit place DK2 is selected as the target visit place, the control unit 20 uses a point on the return route R away from the facility of the route visit place DK2 by the predetermined distance T in the future at the route visit place DK2. It is set as a guide point EK2 where guidance EK2 of the event to be held is performed.

  When the guidance point for the target visited place is set in either step S150 or S160, the control unit 20 determines whether or not there is an unselected return destination place as the target visited place by the function of the event guide unit 21c. (Step S170). That is, the control unit 20 determines whether or not the processing for setting the guide points for all the return destinations has been completed. When it is not determined that there is an unselected return trip destination as the target visit location (step S170: N), the control unit 20 returns to step S140 by the function of the event guide unit 21c and selects a new target visit location. . By repeatedly executing the above processing, a guide point can be set for each return destination.

  Next, guidance information transmission processing executed by the server 10 as the navigation system will be described. In the guidance information transmission process, event guidance information 130c for guiding an event to be held in the future at the visited place visited on the outbound route O is transmitted to the vehicle-mounted device 110 together with the route information 30b (130b) indicating the return route R. And is executed after the guidance point setting process described above. FIG. 4A is a flowchart of guidance information transmission processing.

  First, the control part 20 produces | generates the route information 130b of a scheduled travel route (return route R) (step S200). That is, the route information 130b that identifies a series of road sections constituting the return route R to the home H is generated. Next, by the function of the event acquisition unit 21b, the control unit 20 acquires event information for each of the guide points set on the return route R (step S210). In the case of FIG. 2A, information indicating event guidance ES and EK1 to EK3 at each of the guidance points PS and PK1 to PK3 set on the return route R is acquired from the event information 30c. In addition, since the information about the event held in each point is accumulate | stored previously in the event information 30c, the control part 20 can acquire the guidance ES, EK1-EK3 of the event in guidance point PS, PK1-PK3. In the present embodiment, at least the content of the event and the period of the event are guided as the event guide ES, EK1 to EK3.

  Next, the function of the event guide unit 21c causes the control unit 20 to generate event guide information 130c in which future event information is associated with each guide point (step S220). Finally, the control unit 20 transmits the route information 130b and the event guide information 130c to the vehicle-mounted device 110 by the function of the event guide unit 21c (step S230).

  An event guidance process executed by the vehicle-mounted device 110 that has received the route information 130b and the event guidance information 130c will be described. FIG. 4B is a flowchart of the event guidance process. First, the control unit 120 of the vehicle-mounted device 110 determines whether or not the vehicle has passed the guidance point by the function of the guidance control unit 121b (step S300). For example, the control unit 120 determines that the vehicle has passed the guidance point when the current position of the vehicle is within the error range (for example, 20 m) of the guidance points PS and PK1 to PK3 indicated by the event guidance information 130c. Also good.

  Next, the function of the guidance control unit 121b causes the control unit 120 to guide an event associated with the guide point that has been passed (step S310). As shown in FIG. 2B, there may be a case where guidance ES ES, EK1-EK3 of events to be held in the future at a plurality of visited locations DS, DK1-DK3 is performed for a single guidance point PS.

(3) Other embodiments:
FIG. 4C is a flowchart (part) of guidance point setting processing according to another embodiment. In another embodiment, step S155 is inserted between step S145 (Y) and step S160 in FIG. In FIG. 4C, when it is determined that the target visited place is a facility (step S145: Y), the function of the event guide unit 21c causes the control unit 20 to make the target visited place (facility) within another return place visited (region). (Step S155).

  FIG. 2C shows an example in which the route visit place DK2 as the target visit place exists in the route visit place DK3 as another return visit place. As described above, there may be a case where a certain area is set as a destination and a facility in the area is specified as an individual destination. In this case, a planned travel route (outward route O) that can visit a representative point in a certain region (such as a point where the central city or administrative office is located) and facilities in the region is searched.

  When it is not determined that the target visited place (facility) exists in another return place visited (region) (step S155: N), the control unit 20 uses the function of the event guide unit 21c to start from the target visited place (facility). A point on the return route R separated by a predetermined distance T is set as a guide point for an event to be held in the future at the target visited place (step S160).

  On the other hand, when it is determined that the target visited place (facility) exists in another return place visited (area) (step S155: Y), the control unit 20 determines that the target visited place (facility) is the function of the event guide unit 21c. A point on the return route R exiting from another existing return destination (region) is set as a guide point of an event to be held in the future at the target visited location (step S165). In the case of FIG. 2C, the route visit place DK2 as the target visit place exists in the route visit place DK3 as another return visit place. A point on the return route R to leave is set as a guide point PK3. Therefore, at the guidance point PK3, guidance EK2 and EK3 of events to be held in the future are performed at the route visit place DK2 and the route visit place DK3. In addition, the information on the event held in the via-site DK3 and the information on the event held in the via-site DK2 may be common event information. Therefore, in step S210 of FIG. 4A, the control unit 20 may not acquire redundant information about common events in the route visit place DK2 and the route visit place DK3.

  In addition, even when it is determined that the target visited place (region) exists in another return place visited (region), the control unit 20 uses the function of the event guide unit 21c to make another return route where the target visited place (region) exists. A point on the return route R that exits from the visited place (region) may be set as a guide point for an event to be held in the future at the target visited place.

  In the embodiment, the case where the return route R to the home H is clarified by the route search is illustrated, but the return route R may not necessarily be clarified by the route search. That is, in a situation where the return route R is not clarified by the route search and the user can determine that he is on the return route R, an event to be held in the future on the outbound route O may be guided.

  For example, the function of the event guide unit 21c allows the control unit 20 to hold a future event at the visited location when the user starts moving without searching for a new scheduled route after visiting the final destination on the outbound route O. An event to be performed may be guided to the guide unit. This is because the user has a high possibility of knowing the route to the home H, and when the user is moving without setting a new scheduled travel route, it can be determined that the user has returned home. For example, after the accessory power supply is turned on at the final visited place DS on the outbound route O, the control unit 20 does not receive the route search request information and changes the current position of the vehicle by a threshold value (for example, 100 m) or more. It may be determined that the user has returned home R. If the vehicle-mounted device 110 transmits information indicating the current position to the server 10 for a certain period or every certain traffic distance, the control unit 20 can determine whether or not the current position of the vehicle has changed by a threshold value or more. In this case, since the return route R is not clear, it is difficult to specify a visited place via the return route R. Therefore, the control unit 20 may guide events to be held in the future at all visiting places on the outbound route O, for example, at the timing when the user determines that the user has taken the return route R.

  Further, the function of the event guide unit 21c allows the control unit 20 to change to the visited location when the user moves in the opposite direction on the original scheduled route (outbound route O) after visiting the final destination on the outbound route O. In the future, the guide may guide the event that will be held in the future. When the user learns a way on the outbound route O, if the user travels in the opposite direction to the outbound route O, the user can return to the home H. Therefore, when the user moves in the opposite direction on the outbound route O, the vehicle is judged to have reached the return route R. Because it can. Even when the return path R in the direction opposite to the forward path O is not searched as shown in FIG. 2A, it can be determined that the path in the direction opposite to the forward path O is being traveled based on the trajectory of the current position of the vehicle. Alternatively, the control unit 20 may perform guidance ES, EK1 to EK3 of an event to be held in the future at the visited place DS, DK1 to DK3 on the outbound route O. In addition, the control unit 20 may determine whether or not the vehicle travels in a direction opposite to the forward path O based on the distance or parallelism between the shape of the forward path O and the trajectory.

Based on the distance from the home H to the visited site, the control unit 20 may narrow down the holding period of the event to be guided among the events that will be held in the future at the visited site by the function of the event guiding unit 21c. Here, since it is difficult to revisit as soon as the distance from the home H to the visited place is large, the control unit 20 increases the holding period (start, end, etc.) as the distance from the home to the visited place increases. You may narrow down to guide late events.
[Example of event information]
Facility: ACB Park ・ Event 1
Contents: ACB Winter Festival
Period 1: 2014/12/10 to 2014/12/15
Period 2: 2015/12/11 to 2015/12/16
・ Event 2
Contents: ACB Spring Festival
Period 1: 2015/4/10 to 2015/4/12
For example, in the above example, when the distance from the home H to the visited place (ACB park) is equal to or greater than a threshold (for example, 1000 km), the possibility of revisiting the visited place after six months from the current (2014/11/10) is As small as possible, it may be narrowed down to guide only the period 2 of the event 1 (ACB winter festival).

  After the user leaves the visited area, it is only necessary to provide guidance for an event that will be held in the future at the visited place, and the control unit 20 does not necessarily perform the guidance of the event on the return path R. For example, on the outbound route O, the control unit 20 may guide an event to be held in the future at each route visit place each time the route visit site is left. That is, the control unit 20 is scheduled to be held in the future on the outbound route O at a point that is away from the routed visit site that is a facility by a predetermined distance T, or at a point that leaves the routed visit site that is a region. An event guide may be provided. Of course, the control unit 20 may guide an event that will be held in the future on the outbound route O at a point a predetermined distance before the user arrives at the home H on the return route R.

  Furthermore, it is not always necessary to provide guidance for events that will be held in the future at both the route visit place and the final visit location, and the control unit 20 may provide guidance only for events that will be held in the future at the final visit location. Good. Further, in the present invention, the planned route for the outbound route O does not necessarily exist. For example, when the accessory power supply is turned on at a point other than home H, the control unit 20 may regard the point as a visited place. And the control part 20 may perform guidance of the event to be held in the future at the visited place when the user moves more than a predetermined distance from the point where the accessory power supply is turned on. Further, each means of the navigation system of the present invention may be provided in the vehicle-mounted device 110, and based on the event information acquired by the vehicle-mounted device 110 from the Internet 200 or the like, information on events to be held in the future at the visited place is provided. You may go.

  Moreover, the control part 20 may acquire the point where the accessory power supply was turned OFF / ON among the route destinations as the route visit place. Further, the control unit 20 may acquire a point where an operation other than the OFF / ON of the accessory power source (for example, opening / closing of a door) is performed as a visited place. Furthermore, when traveling on the return route R, the guide point need not be set in advance. For example, the control unit 20 of the server 10 acquires the current position of the vehicle traveling on the return path R by communication, and each time the current position becomes a point that passes the visited place on the outbound route O, a future event is held at the visited place. Information for guiding the event to be performed may be transmitted to the vehicle-mounted device 110.

  The above embodiment is an example for carrying out the present invention, and various other embodiments can be adopted. An event to be held in the future is an event that is held at a visited place, and is an event that at least ends in the future and can be revisited. The future means at least a time later than the user leaves the place of visit. The visited place is a point where the user visits by private car, public transportation or walking, and may be a facility or an area such as an administrative division. When the visited place is an area, an event to be held in the future at the visited place may be an event to be held in the future at any point in the area. The event acquisition means may narrow down event information to be acquired according to the holding period, importance, etc. of the event when acquiring information of an event to be held in the future at the visited place. The event information may be information indicating the contents of the event, the venue, the period of the event, and the like. The event guidance means may be provided in a mobile terminal (on-vehicle device, smartphone, mobile phone, etc.) that moves with the user, or may be provided in a fixed terminal (server, personal computer, etc.) that does not move with the user. In the latter case, event guide means provided in the fixed terminal may transmit information for guiding the event to the mobile terminal by communication or the like.

  Here, the visited place acquisition means, when searching for a scheduled travel route from the departure point specified by the user to the final destination, at least one of the via destination and the final destination on the planned travel route is the said visited location. You may get as Here, the destination (route destination, final destination) specified when searching for the planned route can be regarded as the destination that the user intended to visit, and the destination was visited intentionally. It becomes possible to determine whether or not to revisit the visited place in consideration of the event. Multiple destinations may exist if a final destination and one or more via destinations are specified.

  Further, the event guidance means may cause the guidance unit to guide an event that will be held in the future at the visited place when the user returns home after visiting the final destination. In this way, after the final destination visit, when the user returns to his / her home, the event scheduled to be held in the future at the visited location will be guided, so the planned travel route that has been completed. You can consider whether to revisit the place you visited.

  Further, the event guidance means searches for a new scheduled route to the user's home after the visit to the final destination, and when the user starts passing the new scheduled route, An event to be held may be guided to the guidance unit. Thereby, when a new scheduled route to travel to the home is searched, it can be reliably determined that the user has returned home.

  In addition, the event guide means, when the user starts moving without searching for a new route to be traveled after visiting the final destination, causes the guide unit to guide an event that will be held in the future at the visited location. Also good. Here, there is a high possibility that the user knows the route to his / her home, and when the user is moving without setting a new scheduled route, it can be determined that the user has returned home.

  In addition, the event guidance means may cause the guidance section to guide events to be held in the future when the user moves in the opposite direction on the original scheduled route after visiting the final destination. Good. Here, if the user remembers the road on the outbound route, he can return to his home if he travels in the opposite direction to the scheduled route, so if the user moves in the opposite direction on the original scheduled route, the vehicle Can be judged to have returned.

  Further, the event guidance means may cause the guidance unit to guide an event that is to be held in the future at a visited place that passes when the user travels on the return path when passing the visited place on the return path. In this configuration, since an event to be held in the future is guided at the time of passing the visited place on the return path, it is possible to consider whether or not to revisit the visited place in a situation where the visited place is easy to remember.

  In addition, when the visited place is a facility, the event guide means may guide an event that will be held in the future at the visited place when the user leaves the visited place by a predetermined distance. In this configuration, events that will be held in the future are guided at a stage that is not far away from the facilities at the visited site, so whether to revisit the visited site in a situation that makes it easy to remember the visited site. Can be considered.

  Furthermore, when the visited place is an area, the event guide means may guide an event that will be held in the future at the visited place to the guide section when the user leaves the area. As a result, if the visited area is an area, when the user leaves the area, whether or not to revisit the area in consideration of future events in the area. Can be considered.

  The event guide means may cause the guide unit to guide an event that will be held in the future at a visited place that does not pass when the user returns on the way home when the user starts to pass on the way back. Here, in the case of not passing through the visited place on the return trip, it is possible to guide an event that will be held in the future at the earliest possible stage when traveling on the return trip. That is, it is possible to consider whether or not to revisit the visited place in a situation where the visited place is easy to remember. Here, when starting the return trip, it may be a timing when the passage is resumed at the final destination of the scheduled route (accessory power ON, etc.), or from the final destination of the planned route on the return route. It may be the timing to leave. Therefore, when the final destination of the scheduled route is a region, the start of the return route may be the timing of leaving the final destination region of the planned route on the return route.

  The event guide means may narrow down the holding period of the event to be guided among the events to be held in the future at the visited place based on the distance from the home to the visited place. Here, since it is difficult to revisit as soon as the distance from the home to the visited place is large, the holding period of the event to be guided may be narrowed down based on the distance from the home to the visited place.

  Furthermore, as in the present invention, a method for guiding an event to be held in the future can be applied as a program or a method. In addition, the system, program, and method as described above may be realized as a single device, or may be realized using components shared with each part of the vehicle, and include various aspects. It is a waste. For example, it is possible to provide a navigation system, a navigation system, a method, and a program that include the above devices. Further, some changes may be made as appropriate, such as a part of software and a part of hardware. Furthermore, the invention is also established as a recording medium for a program for controlling the navigation system. Of course, the software recording medium may be a magnetic recording medium, a magneto-optical recording medium, or any recording medium to be developed in the future.
