2. Description of the Related Art Generally, a navigation device, for example, a car navigation device, provides comfortable driving by guiding a traveling route searched based on destination data, own vehicle position data, and road map data by voice or screen display. In this case, the user may stop by a facility such as a restaurant for a meal on the way from the departure point to the destination.

There are first and second conventional examples, mainly as described below, of a specific operation for performing a search for performing route guidance relating to a stopover.

That is, as a first conventional example of a stopover search,
There is an example in which a stopover is determined as in the flowchart shown in FIG. 5. First, a final destination is set in step S1, and a search is performed based on the vehicle position detection data and map data in the next step S2. Is started, a search is performed up to the destination, and after obtaining expected arrival time data in step S3,
In step S4, an operation for determining a stop-off point is started based on the estimated arrival time data.

In step S4, the user (driver) himself / herself determines the position of the vehicle at the desired time based on the expected arrival time data as in step S5, and selects one vehicle from among a plurality of facilities near the vehicle. In order to select a facility, determine the approximate location of the vehicle at the time of the meal you want to eat, and temporarily determine the approximate position. Then, in step S6, search for nearby facilities and stop at which facility to eat. Choose what to do,
The search is started by registering the selected facility as a stopover.

[0006] In this way, the search result obtained in step S6 is route-guided by voice and / or screen display in step S7, so that the driver is prompted to travel to the stop-off facility.

On the other hand, as a second conventional example of a stopover search,
There is an example in which a stop-by place is determined as in the flow chart shown in FIG. 6, and the current time and the stop-off time obtained in step S11 during traveling to a preset destination (step S8). The comparison with the desired time is performed in step S9. If the current time does not reach the desired time (in the case of no), the process returns to step S8, and the vehicle continues to run, and the current time reaches the desired time. If so (if yes), the process proceeds to the next step S12.

It is to be noted that how much the vehicle travels in step S8 as shown in step S10 is left to the discretion of the user (driver).

If the answer is YES in step S9, the operation proceeds to the next step S12 to start the operation for determining the stop-off point.

In step S12, when the current time approaches the desired time, the user (driver) himself / herself determines the position of the own vehicle and selects one facility from a plurality of facilities existing in the vicinity thereof. After determining the approximate location of the vehicle at the time of the meal time and temporarily determining the approximate position, in step S13 a search is made for nearby facilities to select which facility to stop at and to eat. The search is started by registering the selected facility as a stopover.

[0011] In this way, the search result obtained in step S13 is route-guided by voice and / or screen display in step S14, so that the driver is prompted to drive to the stop-off facility.

Searching for a dropped-in facility is performed by the operation as in the first or second conventional example as described above, and at the same time, a drop-in place is determined based on the user's own judgment. The driver is prompted to travel to the facility.

[0013]

In a conventional navigation device such as a car navigation system, a stopover search device requires a user to search for a stopover facility at his / her own discretion near a desired stopover time, which is a complicated operation. The user is forced to take time-sensitive driving, which poses a problem in safe driving.In addition, in order to search for drop-in facilities, the vehicle must be stopped for safe driving. Is required, and there is a problem that the user is required to perform a very troublesome operation.

If the stopovers which are likely to be traveling during the meal time are set and registered in advance, the above-mentioned troublesomeness can be solved. Because it is difficult to accurately predict, the time to arrive at the stop-by place will be delayed, so it is necessary to clear the registration of the stop-down place that was initially set and reset the registration of the new stop-down place It is not a complete solution because it creates another problem.

Therefore, an object of the present invention is to search for a facility that drops in the middle of a preset destination so that the user can arrive at the drop-in facility at a desired time by dynamically responding to traffic congestion. A search device for a stop-by place in a navigation device, which can perform the search without forcing the user.
