FIG. 2 is a flowchart showing a processing procedure of the navigation device according to the embodiment of the present invention. The flowchart shown in FIG. 2 is started when a destination is set by the user, for example.

  As shown in FIG. 2, for example, when a destination is set, the navigation device 110 searches for a route to the destination and then guides the route to the vicinity of the destination (step S201).

  While guiding the route to the vicinity of the destination, the navigation device 110 determines whether or not the mobile body is located at the arrival determination distance around the destination (step S202). In step S202, when it is determined that the vehicle is located at the arrival determination distance around the destination (step S202: Yes), the navigation device 110 notifies the user of arrival at the destination (step S203).

  In step S203, after notifying the arrival at the destination, the navigation device 110 determines whether or not predetermined input information has been detected (step S204). That is, the navigation device 110 determines whether or not predetermined input information has been detected after the guidance by the guidance unit 111 is completed. At this time, for example, the navigation device 110 may determine whether or not the input information is detected within a predetermined distance from the point where the arrival at the destination is notified. Moreover, the navigation apparatus 110 is good also as determining whether input information was detected within the predetermined time from the time which alert | reported the arrival to the destination.

  If it is determined in step S204 that the predetermined input information has not been detected (step S204: No), the navigation device 110 ends the series of processes as it is.

  If it is determined in step S204 that predetermined input information has been detected (step S204: Yes), the navigation apparatus 110 changes the arrival determination distance of the feature set as the destination by a predetermined amount ( Step S205). For example, at this time, the navigation device 110 shortens the arrival determination distance by a predetermined amount. In step S205, the navigation device 110 changes the arrival determination distance by a predetermined amount, and then ends the series of processes.

  On the other hand, when it is determined in step S202 that it is not located at the arrival determination distance around the destination (step S202: No), the navigation device 110 determines whether or not predetermined input information has been detected. (Step S206). That is, the navigation device 110 determines whether or not predetermined input information has been detected before the guidance by the guidance unit 111 is completed. At this time, for example, the navigation device 110 may determine whether or not the input information is detected within a predetermined distance to the destination. Further, the navigation device 110 may determine whether or not the input information is detected when the scheduled time of arrival at the destination and the current time are within a predetermined time.

  If it is determined in step S206 that predetermined input information has not been detected (step S206: No), the navigation device 110 returns to step S202 and repeats the above processing.

  If it is determined in step S206 that predetermined input information has been detected (step S206: Yes), the navigation device 110 changes the arrival determination distance of the feature set as the destination by a predetermined amount ( Step S207). For example, at this time, the navigation device 110 extends the arrival determination distance by a predetermined amount. In step S207, the navigation device 110 changes the arrival determination distance by a predetermined amount, and then ends the series of processes.

An appropriate arrival determination distance can be set without renewing the arrival determination distance.

  Furthermore, since the information management server 120 aggregates the arrival determination distances received from the navigation device 110 and distributes the arrival determination distances to a plurality of navigation devices, the plurality of navigation devices can share the changed arrival determination distances. Thereby, the user can receive guidance to an appropriate position based on the arrival determination distance after the change even for the features that he has not performed.

  In addition, if the information management server 120 is configured to receive the changed arrival determination distances from a plurality of navigation devices and total the features for each feature, the data transmitted from each navigation device is flattened and the reliability is improved. Can be improved. Thereby, the user can be guided to an appropriate position based on the arrival determination distance with higher reliability.

  As shown in FIG. 6, the navigation apparatus 311 of the present embodiment waits until a destination is input (step S601: No loop). In step S601, when the destination is input, the navigation device 311 searches for a route to the destination (step S602). For example, the navigation device 311 uses the Dijkstra method to search for a route with the earliest scheduled time to arrive at the destination.

  In step S602, after searching for a route to the destination, the navigation device 311 guides the route to the searched destination (step S603). For example, the navigation device 311 displays the route to the destination on the display 413 and guides the user to the destination.

  While guiding the route to the destination, the navigation device 311 next determines whether or not the vehicle is located at an arrival determination distance around the destination (step S604). In step S604, when it is determined that the vehicle is located at the arrival determination distance around the destination (step S604: Yes), the navigation device 311 notifies the user of arrival at the destination (step S605). For example, the navigation device 311 outputs a voice indicating that the vehicle has arrived at the destination from the speaker 410 and notifies the user.

  In step S605, after notifying the arrival at the destination, the navigation device 311 determines whether or not predetermined input information has been detected (step S606). At this time, for example, the navigation device 311 may determine whether or not predetermined input information is detected within a predetermined distance (for example, within 100 m) from the point where the arrival at the destination is notified. Further, the navigation device 311 may determine whether or not predetermined input information is detected within a predetermined time (for example, within 5 minutes) from the time when arrival at the destination is notified.

  If it is determined in step S606 that the predetermined input information is not detected (step S606: No), the navigation device 311 ends the series of processes as it is. In other words, the navigation device 311 operates as it is when the user does not operate the input device 411 to change the map information display scale or re-search for a new destination, for example. A series of processing ends.

  On the other hand, if it is determined in step S606 that predetermined input information has been detected (step S606: Yes), the navigation device 311 acquires position information of the input point where the input information is detected (step S607).

  In step S607, after acquiring the position information of the input point, the navigation device 311 changes the arrival determination distance of the destination based on the position information of the input point (step S608). For example, the navigation device 311 shortens the arrival determination distance of the destination to the distance from the destination to the input point.

  In step S608, after changing the arrival determination distance of the destination, the navigation apparatus 311 transmits the changed arrival determination distance to the information management server 331 (step S609), and ends the series of processes. For example, the navigation device 311 transmits arrival determination distance information that associates the set destination with the changed arrival determination distance of the destination to the information management server 331. Thereby, the information management server 331 can acquire the feature whose arrival determination distance has been changed and the changed arrival determination distance.

  On the other hand, if it is determined in step S604 that it is not located at the arrival determination distance around the destination (step S604: No), the navigation device 311 determines whether or not predetermined input information has been detected. (Step S610). At this time, for example, the navigation device 311 may determine whether or not the input information is detected within a predetermined distance (for example, within 100 m) to the destination. Further, the navigation device 311 may determine whether or not the input information is detected when the scheduled time of arrival at the destination and the current time are within a predetermined time (for example, within 5 minutes). .

  If it is determined in step S610 that the predetermined input information has not been detected (step S610: No), the navigation device 311 returns to step S604 and repeats the above processing. That is, the navigation apparatus 311 returns to step S604 when the user operates the input device 411 and does not perform, for example, an operation to delete (cancel) the destination or an operation to cancel the guidance. The above processing is repeated while continuing the guidance.

  If it is determined in step S606 that predetermined input information has been detected (step S610: Yes), the navigation device 311 acquires position information of the input point where the input information is detected (step S611).

  In step S611, after acquiring the position information of the input point, the navigation device 311 changes the arrival determination distance of the destination based on the position information of the input point (step S612). For example, the navigation device 311 extends the arrival determination distance of the destination to the distance from the destination to the input point.

  In step S612, after changing the arrival determination distance of the destination, the navigation apparatus 311 transmits the changed arrival determination distance to the information management server 331 (step S613), and ends the series of processes. For example, the navigation device 311 transmits arrival determination distance information that associates the set destination with the changed arrival determination distance of the destination to the information management server 331. Thereby, the information management server 331 can acquire the feature whose arrival determination distance has been changed and the changed arrival determination distance.

  Although illustration is omitted, in addition to the above processing, the navigation device 311 changes the arrival determination distance based on the received arrival determination distance information when receiving the arrival determination distance information distributed from the information management server 331. It also performs processing. Specifically, for example, when the navigation apparatus 311 receives arrival determination distance information including a certain feature X and its arrival determination distance R from the information management server 331, the arrival determination of the feature X is performed based on this information. A process of updating the distance to R is performed.

  Further, the processing content of the navigation device 321 is the same as that of the navigation device 311, and thus the description thereof is omitted.

(Information management server processing procedure)
Next, the processing procedure of the information management server of this embodiment will be described. FIG. 7 is a flowchart showing the processing procedure of the information management server of this embodiment. Note that the flowchart shown in FIG. 7 is started when, for example, information transmitted from the navigation device is received.

  As shown in FIG. 7, the information management server 331 first waits until it receives arrival determination distance information (step S701: No loop). In step S701, when arrival determination distance information is received (step S701: Yes), the information management server 331 adds up the arrival determination distance for each feature from the arrival determination distance information (step S702). Specifically, for example, the information management server 331 aggregates arrival determination distance information received from a plurality of navigation devices for each feature, and calculates an average value for each feature.

  In step S702, after totaling the arrival determination distance for each feature, the information management server 331 distributes the total arrival determination distance information to the navigation devices 311 and 321 (step S703), and the series of processing ends.

In FIG. 9, a point indicated by a symbol i ₂ is an input point where predetermined input information is detected. In FIG. 9, a circle indicated by a symbol C ₂ is a circle having a radius r ₂ (r ₂ > r ₁ ) centered on the destination icon 802. Here, r ₂ is a linear distance from the destination icon 802 to the point i ₂ .

That is, the navigation device 311 changes the arrival determination distance of the facility A 810 from r ₁ to r ₂ when detecting predetermined input information. Further, along with the change of the arrival determination distance, the route 803 to the destination is also changed to the route 901 from the own vehicle icon 801 to the point i ₂ .

  FIG. 10 is an explanatory diagram (part 3) illustrating a specific display example of the navigation device according to the present embodiment. The explanatory diagram shown in FIG. 10 is a display example when the facility B is set as the destination in the navigation device 311 and the route to the facility B is guided. Here, the facility B is, for example, a large facility (for example, a shopping mall) as in the case of the facility A.

  As shown in FIG. 10, a display screen 1000 is displayed on the display 413. The display screen 1000 is composed of, for example, map information around the vehicle 310 and various icons. First, in FIG. 10, the facility B 1010 is included in the map information around the vehicle 310 displayed on the display screen 1000.

  In FIG. 10, reference numeral 1001 indicates a host vehicle icon 1001 that represents the current position of the vehicle 310. In FIG. 10, reference numeral 1002 denotes a destination icon 1002, which represents the position of the destination. Reference numeral 1003 indicates a route 1003, which represents the searched route to the destination.

In FIG. 10, a circle indicated by a symbol C ₃ is a circle having a radius r ₃ with the destination icon 1002 as the center. Here, r ₃ indicates the arrival determination distance of the facility B 1010 in the default state (for example, the state at the time of shipment of the navigation device 311). Further, in FIG. 10, the point indicated by reference numeral i ₃ includes a route 1003, it is the first intersection point between the circle C _3.

That is, the navigation device 311 extends a link from the vehicle icon 1001 to the vicinity of the destination icon 1002 in the default state, and forms a route to the point i ₃ . For example, when the vehicle icon 1001 is positioned on the point i ₃ , it is determined that the vehicle has arrived at the destination, and the user is notified that the vehicle has arrived at the destination.

For example, when detecting predetermined input information such as changing the scale of the displayed map information, the navigation device 311 acquires position information of the input point where the input information is detected. In FIG. 10, a point indicated by a symbol i ₄ is an input point where predetermined input information is detected. In FIG. 10, a circle indicated by a symbol C ₄ is a circle having a radius r ₄ (r ₄ <r ₃ ) centered on the destination icon 1002. Here, r ₄ is a linear distance from the destination icon 1002 to the point i ₄ .

That is, the navigation device 311 changes the arrival determination distance of the facility B 1010 from r ₃ to r ₄ when detecting predetermined input information. Further, along with the change of the arrival determination distance, the route to the destination is also changed, and the route 1003 from the own vehicle icon 1001 to the point i ₄ is changed.

  As described above, the navigation device 311 according to the present embodiment, when detecting predetermined input information before or after completion of guidance to the destination, arrives at the arrival determination distance of the feature set as the destination. To change.

Thereby, the user can arrive at the destination without hesitation, and wasteful consumption of gasoline can be prevented.

  Further, according to the navigation device 311 of the present embodiment, the arrival determination distance is changed by, for example, input information based on the user's operation, so that the difference is small for each user, unlike the speed and the driving level. It is possible to change the arrival determination distance suitable for sharing. As a result, the user can use the arrival determination distance collected from other users effectively.

  According to the navigation device 311 of this embodiment, the arrival determination distance of the feature is sequentially updated based on the input information input by the user, so information such as the area of the facility is obtained. There is no need for the manufacturing side to prepare in advance, and processing can be easily performed without performing complicated calculations using information such as the area of the facility.

  Furthermore, since the information management server 331 aggregates the arrival determination distances received from the navigation device 311 and distributes the arrival determination distances to the navigation device 321 or the like, the changed arrival determination distance can be shared by a plurality of navigation devices. Thereby, each user can receive guidance to an appropriate position on the basis of the arrival determination distance after the change even in the feature that he has not performed.

  Further, if the information management server 331 is configured to receive the changed arrival determination distances from a plurality of navigation devices and total the features for each feature, the data transmitted from each navigation device is flattened and the reliability is improved. Can be improved. Thereby, the user can be guided to an appropriate position based on the arrival determination distance with higher reliability.
