In setting the route, the difficulty level of the route may be changed according to the difficulty level set in the setting 2. Next, the route information that serves as a hint for estimating the first destination (first stop) is calculated according to the difficulty level set in the setting 2 and transmitted to the navigation device 8 (step S9).

In the present embodiment, the route information that serves as a hint for estimating the next destination (the next waypoint) is to proceed in which direction at which branch point (in which intersection or at which intersection to turn). Information) and image information of the branch point (intersection). Then, in the present embodiment, the route information is calculated such that the details of the route information change according to the difficulty level set in step S8. Specifically, as shown in FIG.
The most detailed level 1 depending on the difficulty level selected
To the most rough level 5 intersection information is selected, image information necessary for this is retrieved from the server, and processed so that the navigation device 8 can display it.

In this embodiment, at level 1, an image of a turning point (intersection) to be turned, a traveling direction at the turning point (intersection), and all the facilities around the turning point are presented as the intersection information. In, the image of the intersection to be turned, the direction of travel at the intersection, and the selected facilities around the intersection are presented as the intersection information. At level 3, the image of the intersection to be turned, and

Further, if the surrounding environment is the rural area, the set difficulty level is not changed and the delivered map is also displayed on all roads. Furthermore, if the surrounding environment is a mountainous area, the set difficulty level is increased by "1" and the distributed map is displayed as all roads.

Further, in the present embodiment, the information center 4
The three destination candidates are included in the route information and transmitted to the navigation device 8, and these destination candidates are presented on the display screen of the navigation device 8 and are selected by the navigation device 8 side. Has been done.

In this embodiment, all the route information regarding the first destination (the first passing point, that is, the first waypoint) is collectively transmitted to the navigation device 8 (step S9). The route information (hint) calculated and transmitted in this way is displayed on the display means of the navigation device 8 (step S10). Therefore, the navigation device 8 obtains all the information for estimating the first destination before moving toward the first passing point.

FIG. 7 is an example of a screen displayed on the navigation device 8 when the difficulty level 1 is selected. As shown in FIG. 7, on the screen, the letters "Turn left at this intersection", "Coffee shop on your right after 300 meters" are used as hints to guess the first passing point, and your vehicle. The position and the destination candidate or a map with is clearly displayed. Here, although the correct destination (first passing point) is, the navigation device 8 does not display that is the correct answer. Furthermore, when the "image" on the screen is clicked, the image information of the intersection to be turned or the like is displayed as a hint according to the set difficulty level.

The occupant of the vehicle refers to these hints to infer and select a destination candidate or a destination that seems to be correct (step S11). When the destination candidate is selected, the screen in FIG. 8 is displayed, and when the destination candidate is selected, the screen in FIG. 9 is displayed to confirm the selection.
When “OK” is selected, route guidance to the selected destination candidate is performed (FIGS. 10 and 11), and the driver follows the guidance to advance the vehicle. After that, the navigation device 8 continues to transmit the current position to the information center 4 side (step S11), and the information center 4 which has received this transmits the position of the navigation device 8 to the mobile terminal 6 (step S12), It is displayed on the mobile terminal 6 side (step S13).

Further, the information center 4 determines whether or not the vehicle is traveling by using the route guidance function (step S
14), when the route guidance function is not used, FIG.
A screen as shown in (1) is displayed on the display means of the navigation device 8 to give a warning (step S15). Further, the information center 4 determines again whether or not the candidate site is selected and the vehicle is traveling by using the route guidance function (step S16), and when the route guidance function is still not used, the processing is ended. . The same processing is performed when the vehicle is traveling without setting the destination candidate location.

In step S14 to step S16, as shown in FIG. 13, a warning is issued when the vehicle runs without selecting the passing point, and the vehicle runs for a predetermined time (or the number of times or distance) without selecting the passing point. At this time, the processing may be terminated.

The vehicle equipped with the navigation device 8 is
Route guidance from the information center 4 side, or the information center 4
When the navigation device 8 arrives at the selected destination candidate destination, for example, the destination candidate destination, by the route guidance on the side of the navigation device 8 according to the instruction from the information center 4, the information center 4 detects this (step S17).

Next, the information center 4 determines whether or not the difficulty level set in the setting 2 is 4 or higher (step S18). When the number is 3 or less in step S18, the process proceeds to step S19, and it is determined whether the arrived destination candidate is a correct destination candidate.

If YES in step S19, that is, if it is a correct destination candidate, the process proceeds to step S20, and it is determined whether or not the arrived destination candidate is the (set passing point number + 1) th point. . Step S2
If YES in 0, that is, if the arrived destination candidate is the (set passing point number + 1) th place, the arrived destination candidate is the final destination, and the process is terminated.

If NO in step S20, the flow advances to step S21 to calculate route information that serves as a hint for estimating the next destination (a transit point, that is, a passing point), and the route information and the purpose of arrival. A message indicating that the candidate site is the correct destination candidate is transmitted to the navigation device 8 and the screen as shown in FIG. 15 is displayed. In this example, since the correct answer is selected as the first passing point (route point), the vehicle position of "when the previous time is selected" is not displayed. Also, FIG.
On the screen of No. 5, three candidate sites for the second passing point (route point) are newly displayed.

If NO in step S19, that is, if the destination candidate is incorrect, the process proceeds to step S22, and the process shown in FIG.
The navigation device 8 is caused to display a screen including a message indicating that the arrived destination candidate is an incorrect destination candidate, as shown in FIG. This screen has buttons for additional hints. Two types of additional hints can be selected: "same hint as last time" and "hint from current position".

When it is determined in step S18 that the number is 4 or more, the process proceeds to step S23, and it is determined whether or not the arrived destination candidate is the (set passing point number + 1) th point. YES in step S23, that is, the destination candidate that has arrived is (the number of set passing points +
If the result is (1) th, the destination candidate destination that has arrived is the final destination, so the processing ends.

On the other hand, if NO at step S23,
Proceeding to step S24, regardless of whether or not the arrived destination candidate is correct, route information that serves as a hint for inferring the next destination (a transit point, that is, a passing point) is calculated and transmitted to the navigation device 8. , The screen in which the message “The first passing point is correct” is deleted from the screen of FIG. 15 is displayed. As for the position of the own vehicle, when the destination candidate selected in step S11 is reached, only the position of "when the previous time is selected" is set in step S1.
When the destination candidate selected in 1 is reached, only the position "when the previous time is selected" is displayed. Therefore, on the screen, the position of the own vehicle, three second passing point candidate sites (destination candidate sites), and route information corresponding to the level setting which is a hint for estimating the candidate site are displayed. . This route information is the correct transit point (in this case,
It is calculated on the assumption that the vehicle is at the position where the previous vehicle was selected).

However, in the case of the level 4 or higher, for example, when the vehicle arrives at the waypoint which should have arrived at the third place at the fourth place, etc., the navigation device calculates the route information from the third waypoint. It may be configured to be provided to.

In this embodiment, the "give up" signal, which is a signal requesting the final destination, is sent to the navigation device 8
To the information center 4 (step S25). This "give up"
When a signal is emitted (step S26, step S2
In 7), the information center 4 informs the mobile terminal 6 of that fact, and at the same time, provides the navigation device 8 with information on the final destination. In addition, the route may be guided to the final destination, if necessary.

The present invention is not limited to the above embodiment, but various changes and modifications can be made within the scope of the matters described in the claims.

In the above embodiment, a plurality of destination candidates are
Although it is configured to be displayed on the screen of the navigation device,
When the set difficulty level is high, such a display may not be performed, and the operator of the navigation device may use the function of the navigation device or the like to set the estimated next objective on the navigation device. .

Further, in the above embodiment, the on-vehicle navigation device is used as the navigation device, but it is also possible to use another device having a communication function, a display function and a route guidance function as the navigation device.
