Specifically, for example, when the user gets off the vehicle with the window slightly opened during summer daytime when the outside air temperature is high and the amount of sunlight is high, the user intentionally prevents the temperature inside the vehicle from rising. It is estimated that the vehicle has left the window. Further, when the user opens the window just before getting off and gets off, it is estimated that the user intentionally opened the window and left the vehicle.

  The water intrusion prediction unit 13 has a high possibility of water entering the vehicle based on the output of the window state detection unit 36, the raindrop sensor 37, the outside camera 34, map information, and road information received by the road-to-vehicle communication device 47. It is determined whether or not.

  Specifically, the water intrusion prediction unit 13 includes a rain precipitation prediction unit 24, a water splash prediction unit 25, and a car wash prediction unit 26 therein.

  The rainfall prediction unit 24 uses the window opening amount output by the window state detection unit 36 and the rain amount of rain output by the raindrop sensor 37 to determine whether or not there is a high possibility of rain in the vehicle. judge. For example, if the window opening amount is large or if there is a lot of rainfall, it is determined that there is a high possibility that the vehicle will rain. If the window opening amount is small and the rainfall amount is small, the rain It is determined that the possibility of getting down is small.

  The water splash prediction unit 25 determines whether there is a possibility of water entering the vehicle due to water splash. Water splash occurs when there is a puddle around the vehicle. Whether or not there is a puddle around the vehicle can be determined by performing image processing on the output of the outside camera 34. In addition, when it is raining or there is a possibility of water splashing after it rains, a rain history is created from the output of the raindrop sensor 37 to check whether it has been raining. judge.

  Furthermore, regardless of the presence or absence of rainfall, water splashes can be predicted by acquiring information by the road-to-vehicle communication device 47 in a place where a puddle has been generated for a long time.

  The warning processing unit 22 is a processing unit that executes warning processing using the notification system 40 and the communication system 44 when the selection processing unit 21 selects execution of warning to the user. When the selection processing unit 21 selects execution of window closing control, it is a processing unit that operates the window control mechanism 43 to execute window closing.

  Specifically, the selection processing unit 21 monitors the output of the water intrusion prediction unit 13 regardless of whether or not the user is on board, and the water intrusion prediction unit 13 determines that “the possibility of water entering the vehicle”. When it is determined that “is high”, the execution of the warning process or the window closing process is selected.

  Further, when the user gets off, based on the output of the intention determination unit 12, when the user intentionally opens the window and gets off, the user does not perform the warning process or the window closing process. When the user forgets that the vehicle has been opened and gets off the vehicle, the user selects execution of warning processing or window closing processing.

  Further, when the situation changes after the user intentionally opens the window and gets off, execution of warning processing or window closing processing for the user is selected. That is, if it is estimated by the intention estimation unit 12 that the user has opened the window to prevent the temperature inside the vehicle from getting off, there is no possibility that the temperature inside the vehicle will rise (the outside air temperature has dropped after getting off, the amount of sunlight If the user has fallen, the sunset is approaching, or the like, the user is selected to perform warning processing. Similarly, when it rains after opening the window and getting off, it is selected to perform warning processing for the user or execution of window closing processing.

  In addition, even if the user leaves the vehicle intentionally, even if the window is intentionally opened, if the opening amount is more than a predetermined amount, for example, if it is opened more than the arm can enter, from the viewpoint of preventing vehicle theft. It is desirable to warn the user.

  Next, the processing operation of the window management device 1 will be described with reference to a flowchart. FIG. 2 is a flowchart for explaining the processing operation of the window management apparatus 1 assuming that the user is in the vehicle. This processing flow is repeatedly executed during the operation of the window management apparatus 1.

  As shown in the figure, the window management device 1 first determines whether or not the window is open based on the output of the window state detection unit 36 (step S101), and if the window is closed (step S101). Step S101, No), the process ends.

On the other hand, when the window is open (step S101, Yes), the water intrusion prediction unit 13 obtains the rain history by the raindrop sensor 37, the image processing for the output of the outside camera 38, the map information around the own vehicle, and the road-to-vehicle communication. The occurrence of water splash is predicted from the received information (step S102).
As a result, when there is no possibility of water splash (No at Step S103), the water intrusion prediction unit 13 determines whether or not it is raining from the output of the raindrop sensor 37 (Step S104). If it is raining (step S104, Yes), the water intrusion prediction unit 13 predicts whether or not it will rain into the vehicle based on the rainfall amount and the opening amount of the window (step S105). ).

  When it is not raining (Step S104, No), or when there is no possibility of rain (Step S106, No), the water intrusion prediction unit 13 performs image processing on the output of the outside camera 38, and surroundings of the own vehicle. From the map information of the vehicle, information obtained by road-to-vehicle communication, and the like, it is predicted whether or not the vehicle will be washed (step S107). If there is no possibility of washing (step S108, No), the window management device 1 ends the process.

  And when there is a possibility of water splash (step S103, Yes), when there is a possibility of rain (Step S106, Yes), when there is a possibility of car wash (Step S108, Yes), selection The processing unit 21 selects notification to the user or window closing control, executes the processing selected by the warning processing unit 22 and the window control unit 23 (step S109), and ends the processing.

  Next, the processing operation of the window management device 1 when the user gets off will be described with reference to FIG. This process flow is a process that starts when the absence detection unit 11 detects a user's absence.

  When the absence detection unit 11 detects the user's absence, the window management device 1 first determines whether or not the window is open based on the output of the window state detection unit 36 (step S201). If the window is closed (No at Step S201), the process is terminated.

  On the other hand, when the window is open (step S201, Yes), the intention determination unit 12 determines whether the window is opened immediately before the user gets off (step S202). As a result, if the window is opened immediately before getting off (Yes in step S202), the intention determination unit 12 estimates that the user has opened the window intentionally (step S206) and ends the process. To do.

  On the other hand, if it is not immediately before getting off that the window has been opened (No in step S202), the intention determination unit 13 next determines whether or not the opening amount of the window is equal to or greater than a predetermined amount (step S203). .

  As a result, if the opening amount of the window is less than the predetermined amount (step S203, No), the intention determination unit 13 determines whether or not a temperature increase in the vehicle is predicted from the outside air temperature or sunlight. (Step S204).

  And if the temperature rise in a vehicle is predicted (step S204, Yes), the intention determination part 12 will estimate that the user has opened the window intentionally in order to prevent a vehicle temperature rise (step S206). The process is terminated.

  On the other hand, when there is no possibility of temperature rise in the vehicle (No at Step S204), or when the opening amount of the window is a predetermined amount or more (Yes at Step S203), the selection processing unit 21 notifies the user or closes the window. The control is selected, the process selected by the warning processing unit 22 and the window control unit 23 is executed (step S205), and the process ends.

  Next, the processing operation of the window management device 1 after the user gets off will be described with reference to FIG. This process flow is a process assuming that the user gets off the vehicle by opening the window with the intention of preventing the temperature rise in the vehicle, and is repeatedly executed after the user gets off the vehicle.

  First, window management device 1 acquires outside temperature, sunshine, and time information from outside temperature sensor 34, sunshine sensor 35, and navigation device 2, respectively (Step S301). It is determined whether or not (step S302).

  As a result, if there is no possibility that the in-vehicle temperature increases (No in step S302), the selection processing unit 21 selects a warning process for the user, and the in-vehicle temperature may increase using the warning processing unit 22. It is notified that it has disappeared and the window remains open (step S304), and the process is terminated.

  On the other hand, when there is a possibility that the vehicle interior temperature may increase (step S302, Yes), the window management device 1 next determines whether or not it is raining (step S303). As a result, if it is raining (step S303, Yes), the selection processing unit 21 selects the warning process and the window closing process, closes the window using the window control unit 23, and also outputs the warning processing unit 22. Is used to notify that it has started raining and that the window has been closed (step S305), and the process is terminated.
