Next, the operation of the navigation system 1 according to the first embodiment of the present invention will be described with reference to the flowchart shown in FIG. Note that the control program according to this flowchart is controlled by the system control unit 7.

It is assumed that the schedule information such as the location of the visit destination, the scheduled visit time, the name of the visitor, the contact telephone number, etc. is registered in the schedule storage unit 51 by the operation input unit 55 by the user in advance. I do.

In step S10, the portable terminal adapter 2
9 is connected to the portable terminal 50, the system control unit 7
Reads out menu screen data for selecting a function to be executed from the memory unit 9 and transmits the menu screen data via the display control unit 17 to the VRA.
Stored in the M unit 19, and the VRAM
The menu screen data is read from the unit 19 at the display rate and displayed on the display unit 21. Then, when “display schedule” is selected from the menu by the user's operation, the schedule information of the day is read from the schedule storage unit 51 of the portable terminal 50, and the R in the system control unit 7 is read.
After being stored in the AM, the display unit 2 is displayed via the display control unit 17.
1 displays a schedule list.

In step S20, when the desired schedule information is selected from the displayed schedule list by the operation of the operator, the selected schedule information (the place and time of the scheduled visit, the scheduled visit time, and the The name and the contact telephone number) are displayed on the display unit 21.

In step S30, the operation input section 25 selects whether or not to set the displayed destination location to be visited as the destination. If it is selected by the operation input unit 25 to set the place to be visited as the destination, the process proceeds to step S40, where the position information of the place to be visited is input to the system control unit 7, and the place to be visited is Is set as the destination. On the other hand, if it is selected not to set the place to be visited as the destination, the destination setting menu ends.

After the destination is set, the operation input section 25 selects whether or not to start a route search in step S50. If it is selected by the operation input unit 25 to perform the route search, the process proceeds to step S60. If it is selected not to perform the route search, the destination setting menu is ended. In step S60, the desired arrival time (time earlier than the scheduled visit time by a predetermined time) is calculated. Next, the current position information detected by the GPS receiver 5 is taken into the system control unit 7. Then, in accordance with the designated destination information and the current position information, a node or a road link recorded on a CD-ROM is searched based on a well-known Dijkstra method or the like to create route data of a recommended traveling route. I do. Further, an estimated time of arrival at the destination when traveling on the recommended route is calculated based on distance information from the current position to the destination, traffic information acquired by the traffic information receiver 27, and the like.

In step S70, the desired arrival time is compared with the expected arrival time to determine whether or not there is a route to reach the destination by the desired arrival time. When it is determined that there is a route that can be reached by the desired arrival time, the process proceeds to step S80, and when it is determined that the route cannot be reached by the desired arrival time, the process proceeds to step S110.

In step S80, the system control unit 7
Converts the map data corresponding to the narrow area map around the current position into C
The map data is read from the CD-ROM via the D-ROM drive device 15 and the narrow-area map data is developed on the VRAM unit 19 via the display control unit 17. Next, V is set via the display control unit 17.
The route data is superimposed on the map data stored in the RAM unit 19 and read at a display rate, and read out at the display unit 21.
To display recommended routes. In this way, the vehicle mark is displayed together with the recommended route on the narrow area map around the current position.
And the route guidance is started.

In step S90, the current position information detected by the GPS receiver 5 is fetched into the system control unit 7,
The estimated arrival time at the destination when traveling on the recommended route is calculated based on distance information from the current position to the destination, traffic information, and the like. Then, by comparing the desired arrival time with the expected arrival time, it is determined whether or not to arrive at the destination by the desired arrival time. If you can arrive by the desired arrival time,
On the other hand, if it is determined that the vehicle cannot arrive by the desired arrival time, the process proceeds to step S110. In step S100, it is determined whether the vehicle has arrived at the destination. If the vehicle has arrived at the destination, the route guidance is ended. If the vehicle has not arrived at the destination, the process returns to step S90 and the route guidance processing is repeated.

If it is determined that it is impossible to arrive by the desired arrival time, in step S110, it is difficult to arrive at the scheduled time of visit. Do you want to contact the visitor?
Is displayed, and whether or not to contact is selected by the operation input unit 25. If it is selected by the operation input unit 25 to contact the user, the process proceeds to step S120.
Then, the mode is switched to the hands-free telephone mode, and the communication device 53 is controlled so as to make a call to the contact telephone number registered in the schedule. The communication device 53 makes a call to the designated contact telephone number, and a ring tone output from the communication network is output to the speaker 24. Here, when the communication device 53 is connected to the other party's telephone, a response generated by the other party is output from the speaker 24. In addition, a response generated by the user is transmitted to the other party via the microphone 23.

In step S130, whether or not to continue the route guidance is selected by the operation input unit 25. If it is selected to continue the route guidance, step S1
Proceeding to 40, the vehicle mark is displayed on the display unit 21 along with the recommended route on the narrow area map around the current position, and the route guidance is continued. On the other hand, when it is selected to end the route guidance, the display of the map information is stopped, and the route guidance is ended.

In step S150, it is determined whether the vehicle has arrived at the destination. If the vehicle arrives at the destination, the route guidance is terminated, while if the vehicle has not arrived at the destination,
Returning to step S140, the process is repeated until the vehicle arrives at the destination.

As described above, the schedule information such as the scheduled visit location and the scheduled visit time read from the schedule storage unit 51 of the portable terminal 50 is stored in the navigation device 3, and the scheduled visit location is set as the destination. . And
Route search / calculation of expected arrival time is performed, and if it is not possible to arrive by the desired visit time (time earlier than the scheduled visit time by a predetermined time), it is displayed on the display unit 21 that the arrival at the scheduled visit destination is delayed. At the same time, the communication device 53 sends a call to the contact telephone number of the visitor, whereby the passenger and the visitor can be reliably notified.
