  As shown in FIG. 2, first, the route search condition transmission unit 102 b of the terminal device 100 transmits a route search condition including at least a departure place and a destination input by the user via the input unit 116 to the navigation server 200. Transmit (step SA-1). Here, the departure place may be the current position of the user of the terminal device 100 based on the current position information acquired by the current position information acquisition unit 102a. The route search condition may further include a waypoint.

  Then, the route search condition receiving unit 202a of the navigation server 200 receives the route search condition including at least the departure place and the destination transmitted from the terminal device 100 (step SA-2).

  Then, the guidance route search unit 202b of the navigation server 200 obtains the guidance route from the departure point to the destination that satisfies the route search condition including at least the departure point and the destination received by the route search condition reception unit 202a, using the network database. Search is performed using the network data stored in 206a and the traffic information stored in the traffic information database 206b to generate guide route data (step SA-3). Here, when the route search condition further includes a waypoint, the guide route search unit 202b may search for a guide route via the waypoint.

  Then, the guide route traffic information extraction unit 202c of the navigation server 200 extracts the traffic information on the guide route searched by the guide route search unit 202b from the traffic information database 206b as guide route traffic information (step SA-4). Here, the traffic information may be traffic information, traffic distance, transit time between two points on the road, traffic fault information, and / or weather information such as a weather warning.

  Then, the route guidance information transmission unit 202d of the navigation server 200 transmits the route guidance information including at least the guidance route data and the guidance route traffic information to the terminal device 100 (step SA-5). Here, the route guidance information may further include lane information of the guidance route stored in the network database 206a. The route guidance information may further include map data of a map including the guidance route stored in the map database 206d. The route guidance information may further include guidance data (display guidance data, voice guidance data, etc.) stored on the guidance database 206e and output on the guidance route.

  Then, the guide route data storage unit 202e of the navigation server 200 stores the guide route data in the route guide information database 206c (step SA-6). Here, the guide route data storage unit 202e may store the guide route data generated by the guide route search unit 202b in the route guide information database 206c. The guide route data storage unit 202e stores the newly set guide route data over the existing guide route data when the existing guide route data is stored in the route guide information database 206c. Also good.

  Then, the guide route traffic information storage unit 202f of the navigation server 200 stores the guide route traffic information in the route guide information database 206c (step SA-7). Here, the guide route traffic information storage unit 202f may store the guide route traffic information extracted by the guide route traffic information extraction unit 202c in the route guide information database 206c. The guide route traffic information storage unit 202f overwrites the existing guide route traffic information with the newly set guide route traffic information when the existing guide route traffic information is stored in the route guide information database 206c. May be stored.

  And the route guidance information receiving part 102c of the terminal device 100 receives the route guidance information transmitted from the navigation server 200, and stores it in the route guidance information file 106a (step SA-8).

  Then, the current position information acquisition unit 102 a of the terminal device 100 is detected by the position information calculated from the position information signal received from the position transmission device 500 by the position acquisition unit 112 and / or the direction sensor of the position acquisition unit 112. The direction information and the like of the traveling direction thus obtained are acquired as the current position information of the user of the terminal device 100 (step SA-9). Here, the current position information acquisition unit 102a may acquire information on the current position input by the user via the input unit 116 as the current position information of the user of the terminal device 100. Further, the current position information acquisition unit 102a may acquire the current position information of the user of the terminal device 100 every predetermined time.

  Then, the destination determination unit 102d of the terminal device 100 includes the destination included in the route search condition input by the user via the input unit 116 in step SA-1, and the current position information in step SA-9. It is determined whether or not the current position of the user of the terminal device 100 based on the current position information acquired by the acquisition unit 102a matches (step SA-10).

  If the destination determination unit 102d of the terminal device 100 determines in step SA-10 that the destination included in the route search condition matches the current location of the user of the terminal device 100 (step SA- 10: Yes), the process is terminated.

  On the other hand, the route guidance unit 102e of the terminal device 100 determines that the destination included in the route search condition by the destination determination unit 102d does not match the current position of the user of the terminal device 100 in step SA-10. If it is made (step SA-10: No), the guide route data included in the route guide information stored in the route guide information file 106a is added to the map data included in the route guide information stored in the route guide information file 106a. The guide route traffic included in the current location information of the user of the terminal device 100 acquired by the current location information acquisition unit 102a in step SA-9 and / or the route guide information stored in the route guide information file 106a. Route guidance is executed by displaying a display screen on which information is superimposed on the display unit 114 (step SA-11).Here, the route guidance unit 102e may further cause the display unit 114 to display a display screen based on the lane information included in the route guidance information stored in the route guidance information file 106a. The route guidance unit 102e may display the display screen based on the lane information transmitted from the navigation server 200 on the display unit 114 by combining the basic pattern image data stored in the route guidance information file 106a. For example, when there is a traffic jam on the guidance route ahead of the current position of the user of the terminal device 100, the route guidance unit 102e displays the lane information of the intersection at the time before the intersection. A display screen superimposed on data or the like may be displayed on the display unit 114. Further, the route guidance unit 102e further displays display guidance data such as TBT associated with the traveling direction at guidance points (intersections, etc.) on the guidance route included in the route guidance information stored in the route guidance information file 106a. May be displayed on the display unit 114. Further, the route guidance unit 102e may output route guidance information via the voice output unit 118. For example, the route guidance unit 102e may cause the voice guidance data associated with the traveling direction and the like at the guidance point (intersection etc.) on the guidance route included in the route guidance information to be output via the voice output unit 118. . Further, the route guidance unit 102e may start the route guidance execution process when the user inputs a route guidance start instruction via the input unit 116. The route guidance and voice navigation execution processing by the route guidance unit 102e is performed by the terminal device 100 after the start of route guidance and voice navigation (that is, after the start of route guidance by the route guidance unit 102e in Step SA-11). Step SA-5 until the destination is reached (that is, until the destination and the current position of the user of the terminal device 100 are determined to coincide with each other by the destination determination unit 102d in Step SA-10). To step SA-20 and may be performed continuously and / or repeatedly.

  If the control unit 102 of the terminal device 100 determines that the predetermined period has not elapsed after the start of the route guidance by the route guidance unit 102e in step SA-12 (step SA-12: No), the process is performed. The process proceeds to step SA-9.

  On the other hand, if the route confirmation request transmission unit 102f of the terminal device 100 determines in step SA-12 that the predetermined period has elapsed after the start of route guidance by the control unit 102 (step SA-12: Yes), step A route confirmation request including at least the current position information of the user of the terminal device 100 acquired by the current position information acquisition unit 102a in SA-9 is transmitted to the navigation server 200, and the process proceeds to Step SA-9 (Step S-9). SA-13).

  Then, the route confirmation request receiving unit 202g of the navigation server 200 receives the route confirmation request including at least the current position information of the user of the terminal device 100 transmitted from the terminal device 100 (step SA-14).

  Then, the confirmation route search unit 202h of the navigation server 200 receives a route search condition reception unit from the current position of the user of the terminal device 100 based on the current position information included in the route confirmation request received by the route confirmation request reception unit 202g. A confirmation route that is a route to the destination included in the route search condition received by 202a is searched using the network data stored in the network database 206a and the traffic information stored in the traffic information database 206b. Confirmation route data is generated (step SA-15). Here, when the route search condition further includes a transit point, the confirmation route search unit 202h may search for a confirmation route via the transit point.

  And the confirmation route traffic information extraction part 202i of the navigation server 200 extracts the traffic information on the confirmation route searched by the confirmation route search part 202h from the traffic information database 206b as confirmation route traffic information (step SA-16).

  Then, the route determination unit 202j of the navigation server 200 determines whether or not a part of the guidance route matches the confirmation route searched by the confirmation route search unit 202h (step SA-17). Here, for example, even when the current position of the user of the terminal device 100 is present on the guidance route, the route determination unit 202j uses the confirmation route search unit 202h to perform network data and traffic congestion and traffic due to time changes. When a confirmation route that becomes a detour route of the guidance route is searched using traffic information such as regulations, it may be determined that a part of the guidance route does not match the confirmation route. In addition, for example, when the current position of the user of the terminal device 100 does not exist on the guidance route (that is, when the route is out of the route), the route determination unit 202j determines a confirmation route that does not match the guidance route by the confirmation route search unit 202h. Since the search is performed, it may be determined that a part of the guide route does not match the confirmation route.

  When the route determination unit 202j of the navigation server 200 determines that a part of the guidance route does not match the confirmation route searched by the confirmation route search unit 202h in Step SA-17 (Step SA-17). : No), the confirmation route data generated by the confirmation route search unit 202h in step SA-15 is set as new guide route data, and the confirmation route data extraction unit 202i extracted in step SA-16 The route traffic information is set as new guide route traffic information, and the process proceeds to step SA-5.

In the case (step SA-17: Yes), the traffic congestion information of the intersection on the confirmation route included in the guidance route traffic information stored in the route guidance information database 206c and the confirmation route traffic extracted by the confirmation route traffic information extraction unit 202i. It is determined whether or not the traffic congestion information of the intersection on the confirmation route included in the information matches (step SA-18). Here, the traffic information determination unit 202k determines in step SA-17 that a part of the guidance route is matched by the route determination unit 202j and the confirmation route searched by the confirmation route search unit 202h (step SA-17). SA-17: Yes), the congestion distance at the intersection on the confirmation route included in the guidance route traffic information stored in the route guidance information database 206c, and the confirmation route traffic information extracted by the confirmation route traffic information extraction unit 202i. Judgment whether the guidance route traffic information on the confirmation route and the confirmation route traffic information match by determining whether there is a difference between the traffic jam distance at the intersection on the confirmation route and a predetermined value or more. May be. Further, the traffic information determination unit 202k determines in step SA-17 that a part of the guide route matches with the confirmation route searched by the confirmation route search unit 202h by the route determination unit 202j (step SA). -17: Yes), the transit time at the intersection on the confirmation route included in the guidance route traffic information stored in the route guidance information database 206c, and the confirmation route traffic information extracted by the confirmation route traffic information extraction unit 202i. By determining whether or not the transit time at the intersection on the confirmation route differs by a predetermined value or more, it is determined whether or not the guide route traffic information on the confirmation route matches the confirmation route traffic information. May be. Further, the traffic information determination unit 202k determines in step SA-17 that a part of the guide route matches with the confirmation route searched by the confirmation route search unit 202h by the route determination unit 202j (step SA). -17: Yes), included in the traffic regulation information of the intersection on the confirmation route included in the guidance route traffic information stored in the route guidance information database 206c, and the confirmation route traffic information extracted by the confirmation route traffic information extraction unit 202i.
