The basic function of this weather information presentation device is required during the stay at the destination by calculating the staying time at the destination from the current location, the destination, the date and time, and the schedule of the vehicle on which the vehicle is mounted. The weather is judged and presented.

FIG. 2 shows a main routine of the weather information presentation apparatus according to the present embodiment. First, the navigation information (NAVI information:
Here, the travel time, the travel distance, the current location information, the destination location information, and the current time are acquired and output to the analysis unit 103 (step S100).

Next, a stay time calculation process is executed based on the obtained NAVI information and scheduler information to calculate a stay time (step S101).

Next, weather information acquisition processing is executed based on the location information of the destination and the stay time, and the weather information is acquired based on the range for acquiring the weather (step S10).
2).

Subsequently, weather information analysis processing is executed from the range in which the weather information is obtained, and abnormal weather information and rain / snow weather information are obtained (step S103).

Subsequently, based on the weather information, abnormal weather information, and rain / snow weather information, the output unit 105 displays a weather map in which the weather information is added as shown in a display example 1 in FIG. FIG. 8 when there is weather information and rain / snow weather information
As shown in the display example 2, the display of the weather information and the area having the rain / snow weather information are displayed. When all the information is present, the weather information and the rain / snow weather information are displayed as the display example 3 in FIG. At the same time, with regard to the abnormal weather information, display data is created on a scale that allows the user to understand the abnormal weather, and the display 10
6 is displayed (step S104).

The stay time calculation processing in step S101 is as follows.
This is shown in the flowchart of FIG. Analysis unit 103
Then, based on the destination of the navigation information and the date of the current time, the schedule acquisition unit 102 checks whether there is the corresponding schedule information (step S200).
If there is no corresponding schedule information, the destination time table TB1 shown in FIG.
Is obtained on the basis of (Step S20)
1). And when the schedule information is obtained,
The stay time is obtained from the information (step S20)
2). This destination-based stay time table TB1 sets the behavior pattern at the destination, and takes one hour as a road or other travel time, one hour at a resting place, and two hours at a dining room.
It indicates that they will stay for hours, spend 12 hours at resorts, and spend 16 hours at accommodations.

The weather information acquisition processing in step S102 is as follows.
This is shown in the flowchart of FIG. Generally in Japan, the weather changes from west to east. Taking into account the characteristics of the basic weather change, the weather acquisition range is set as follows.

The travel time to the destination obtained in step S101 is added to the stay time at the destination, the sum is multiplied by a predetermined constant α, and the distance at which the weather changes is calculated from the added time. Set as the weather acquisition range (step S3
00).

When the weather acquisition range from the destination is within β times the traveling distance, the weather information of the area within the distance obtained by adding the distance of the weather acquisition range to the distance from the current position to the destination is obtained. Obtained from the unit 100. On the other hand, when the weather acquisition range is other than β times the traveling distance, the weather information of an area within a distance β times the traveling distance from the destination is acquired from the weather information acquiring unit 100 (step S301).

For example, consider the case of display example 1 in FIG. FIG. 7 (a) shows a weather map at a certain point in the whole of Japan, where a cross-hatched area A is a rainy area,
The shaded area B is a cloudy area. In this figure, it is assumed that the current position is at point 10 and the destination is at point 20. In this case, the destination 2
You will drive roughly eastward toward zero. If it is predicted from the travel time and the stay time at the destination that the rain area A does not reach the destination 20 while staying at the destination 20, as shown in the display example 1 of FIG. Current position 10
The weather from to the destination 20 is displayed.

On the other hand, the display example 2 shown in FIG. 8 is different from this. As shown in FIG. 3A, the destination 20 is located on the west side of the current position 10 and the time calculated by adding the travel time from the current position 10 to the destination 20 and the staying time at the destination 20. In this case, it is predicted that the destination 20 will enter the rainy area A. In such a case, as shown in a display example 2 of FIG. 2B, when the distance at which the weather changes from the travel time and the stay time becomes β times or more of the travel distance, the vehicle travels from the destination 20. The weather in a range G1 that is β times the distance is displayed. In addition, when it is predicted that the weather will change and rain falls in the future process based on the travel time and the stay time, a map G2 of a rainy area is also displayed at the same time.

The weather analysis processing in step S103 is shown in FIG.
This is shown in the flowchart of FIG. First, if there is abnormal weather information such as typhoon C shown in FIG. 9A, the weather information obtaining unit 100 obtains it. And FIG.
(B) As shown in FIG.
6 is displayed on the abnormal weather screen G3 (step S40).
0).

Next, if the weather acquisition range obtained in the weather information acquisition processing in step S102 is equal to or more than β times the traveling distance, it is determined that rain / snow weather analysis processing is necessary (step S401).

If it is determined in step S401 that the rain / snow weather analysis process is not necessary, the result obtained in the weather information acquisition process is displayed in the same manner as in the display example 2 and the process is terminated (step S4).
02). However, if it is determined in step S401 that the rain / snow weather analysis process is necessary, the weather information in the weather acquisition range is obtained from the weather information obtaining unit 100, and the next rain / snow weather analysis is executed (step S410). .

In step S410, a predetermined area or more
For example, when it is rain or snow in the Kyushu region (step S41)
1) The weather information of the area is output to the output unit 105 as rain / snow weather information (step S412).

In step S410, when there is a local, for example, rain or snow only in Nagano prefecture (step S413), the topographic information of the area is obtained from the topographic information storage unit 104,
When the area is a mountain area, it is rainy season and it is rainy, or when it is snowfall and it is snowy, for example, the Chugoku region, the Hokuriku region The information is acquired from the acquisition unit 100 and output to the output unit 105 as rain / snow weather information (step S414). On the other hand, in step S410, it is rain or snow locally (step S413), and the terrain information of the area is obtained from the terrain information storage unit 104. If it is snowfall when it is not the time of falling or snowfall, it is assumed that there is no rain / snow weather information (step S415). Thereby, it is possible to avoid erroneously predicting and displaying the destination as rain or snow when the user arrives based on the local rain / snow information.

Although FIGS. 7 to 9 show the entire map of Japan, if high-speed processing is required, instead of acquiring the weather information of the entire Japan, the weather information within the above-described range is acquired and displayed. It is good to do.

Further, in the above embodiment, when the weather condition of the destination is predicted to be deteriorated while the arrival is scheduled and while staying there, the weather condition is deteriorated.
In other words, the state of the geographical movement of the rain cloud is displayed, but the present invention is not particularly limited to this.
Even in bad weather such as snow, it is necessary to display a weather condition in which the sky rises when the vehicle arrives at the destination from the cloud. Therefore, during the arrival time or during the subsequent stay period, the weather condition of the area where the weather condition of the destination can be predicted by the geographical movement of the weather condition may be displayed, not limited to fine weather or bad weather. .

Furthermore, in the above-described embodiment, the region is limited to Japan, but the weather information presenting apparatus of the present embodiment transmits weather information and topographical information according to the country or region where the device is used. By customizing to reflect, it can be applied to any region of the world without being limited to countries and regions.
