Based on the determination result of the display determination unit 72, the display control unit 73 causes the display unit 63 to display a display on the plan view of the parking lot in which the parking section in which the opening direction of the door of the vehicle matches the wind direction can be confirmed. Further, the display control unit 73 can confirm a door whose opening direction coincides with the wind direction among the doors of the vehicle for each parking lot in the plan view of the parking lot based on the determination result of the display determination unit 72. The display may be displayed on the display unit 63.

The display of information based on the wind speed information in the parking lot will be described with reference to FIGS. 6 and 7. FIG. 6 is a schematic view illustrating an example of display in a parking lot. FIG. 7 is a schematic diagram illustrating another example of display in a parking lot. The parking lots shown in FIGS. 6 and 7 are parking lots such as outdoor coin parking lots. In the parking lot, as display units 63, a display unit 63m, which is a display installed at the entrance, and a display unit 63n, which is an LED lamp installed in each parking lot, are installed.

The display control unit 73 displays information on the display unit 63m installed around the entrance of the parking lot. For example, as shown in FIG. 7, the display control unit 73 outputs a control signal for displaying a plan view image in which all parking lots of the parking lot are displayed to the display unit 63m. For example, the display control unit 73 outputs a control signal to the display unit 63m to display the parking section determined by the display determination unit 72 that the opening direction of the door of the vehicle matches the wind direction in a color different from that of the other parking sections. For example, in the plan view of the parking lot, the display control unit 73 outputs a control signal to the display unit 63m for displaying an image in which the color of the side where the opening direction of the vehicle door matches the wind direction is changed for each parking lot. You may. The display control unit 73 displays text information such as "Caution for strong winds" or "Please get off from the sliding door" when there is a parking lot where it is determined that the opening direction of the vehicle door matches the wind direction. The control signal may be output to the display unit 63m.

The display control unit 73 displays information on the display unit 63n installed in the parking lot of the parking lot. For example, as shown in FIG. 6, the display control unit 73 outputs a control signal for lighting the display unit 63n installed at a position corresponding to the parking section determined that the opening direction of the vehicle door matches the wind direction. ..

In the above description, as the wind speed information acquisition unit, the wind speed information collection unit 51 of the server device 40 collects the wind speed information from the in-vehicle device 10, but the present invention is not limited to this. For example, wind speed information estimated from video data taken by a surveillance camera installed around the parking lot may be collected, or wind speed information may be collected from an external server or the like that stores weather information.

In the above, the server device 40 has been described as having the notification determination unit 53, but the present invention is not limited to this. When the server device 40 does not have the notification determination unit 53, the notification control unit 54 transmits notification information including wind speed information around each parking lot to the management device 60 of each parking lot regardless of the wind speed. do it.

The wind speed estimation unit 30 has been described as estimating the wind speed based on the correlation data, but the method for estimating the wind speed is not limited to this. A learning model generated by machine learning may be used to estimate the wind speed. The control unit 20 of the in-vehicle device 10 stores, for example, a learned model for estimating the wind speed from the image data in which the bending of the electric wire, the shaking of the cloth, the shaking of the trees, etc. are captured in a storage unit (not shown). Then, the wind speed estimation unit 30 reads out the stored learned model, reproduces it, and estimates the wind speed from the captured video data.

In the above description, the wind speed information is estimated from the video data by the in-vehicle device 10 and the wind speed information is transmitted to the server device 40, but the present invention is not limited to this. Video data may be transmitted from the in-vehicle device 10 to the server device 40, and the server device 40 may estimate the wind speed information.

In the above, the notification system 1 has been described as including the in-vehicle device 10, the server device 40, and the management device 60, but the notification system 1 is not limited thereto. The notification system 1 may be composed of only the in-vehicle device 10 and the management device 60. In this case, the in-vehicle device 10 may be provided with the functions of the server device 40. More specifically, the wind speed estimation unit 30 of the in-vehicle device 10 functions as a wind speed information acquisition unit. Further, the in-vehicle device 10 has a function of a notification control unit. The in-vehicle device 10 transmits wind speed information to the parking lot management device 60 located around the in-vehicle device 10 by the notification control unit.
