JP 2010-159615 A

  However, in the alarm device of Patent Document 1, although it is possible to notify the user of forgetting to close (open) the window, it is not known which window in the vehicle is open (forgotten to close). Therefore, the user who has heard the notification sound from the alarm device must return to the vehicle and search for a window that remains open, and the user often has to do so to close the window.

  An object of the present invention is to provide an alarm device for a vehicle that can suppress annoyance when a user closes a window that remains open after a notification sound for notifying the user of forgetting to close the window is generated. is there.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
An alarm device for a vehicle that solves the above problem includes a speaker that is provided corresponding to each window of the vehicle, and a detection unit that detects an open state of the window for each window. When the ignition switch of the vehicle is turned off, the apparatus also sequentially outputs a notification sound about the open state of the window from the speaker corresponding to the open window of the speakers. Prepare.

  According to the above configuration, when the user turns off the ignition switch in order to get out of the vehicle, among the speakers provided corresponding to the windows of the vehicle, the window is opened from the speaker corresponding to the opened window. Notification sound about the open state is output in order. For this reason, the user can hear that the notification sound about the window being opened is emitted from the speaker corresponding to the window in the opened state before getting off the vehicle. Furthermore, since the user can know not only that the window is open but also the position of the window in the open state based on the notification sound, the user can close the window without having to search for the open window. . Therefore, the user who hears the notification sound feels annoyed when closing a window that has been opened, as it does not have to go back to the vehicle once it has exited or look for the window to close it. No need.

  Moreover, it is possible that the said detection part shall acquire the opening degree of the window for every window. In this case, the control unit can output a sound corresponding to the opening of the window from a speaker corresponding to the window, and when the vehicle ignition switch is turned off, the speaker corresponding to each window It is preferable that the sound corresponding to the opening of the window is output in order.

  According to the above configuration, when the user turns off the ignition switch in order to get off the vehicle, sounds corresponding to the opening degree of the window are sequentially output from the speaker corresponding to each window. For this reason, when there is a window in the open state, a sound different from the sound when the window is closed is output from the speaker corresponding to the window as a notification sound for notifying the open state of the window. Further, since the notification sound at this time is a sound corresponding to the opening degree of the window and changes according to the opening degree, the user can know the opening degree of the opened window by listening to the notification sound. Therefore, even if the window is intentionally left open, for example, when it is desired to keep the window open for ventilation in the passenger compartment, the user can listen to the notification sound and intentionally open the window. Whether it is left open or forgotten to be closed can be determined, and an appropriate response can be made based on the determination.

  It is conceivable that the window is opened and closed through the operation of a power window switch provided in the driver's seat of the vehicle, and the opening of the window is acquired for each window with respect to the detection unit. In this case, the control unit can output a sound corresponding to the opening of the window from a speaker corresponding to the window, and when the window is opened and closed through the operation of the power window switch, It is preferable that a sound corresponding to the opening of the window is output from the corresponding speaker.

  According to the above configuration, when the user operates the power window switch to open or close the window, a sound corresponding to the opening degree of the window is output from the speaker corresponding to the window. The opening degree of the window can be grasped without observing the window. Therefore, when the user operates the power window switch in order to adjust the opening of the window, the user can adjust the opening of the window to a desired value by listening to the sound without viewing the window.

  When the sound corresponding to the opening of the window is output from a speaker corresponding to the window, the control unit increases the hardness of the sound as the opening of the window decreases, and the reverberation of the sound. It is preferable to perform at least one of decreasing the degree and increasing the continuity of the sound.

  According to the above configuration, when a sound corresponding to the opening of the window is output from the speaker corresponding to the window, the user can easily recognize the sound corresponding to the opening, and the user who hears the sound opens the window. It becomes easy to grasp the degree.

  In addition, when the window corresponding to the rear seat of the vehicle is closed and operated through the operation of the power window switch, the controller controls the speaker corresponding to the window on the condition that an occupant is seated in the rear seat. It is preferable that a warning sound about the closing operation of the window is output.

  According to the above configuration, when the user of the driver's seat operates the power window switch to close the window corresponding to the rear seat, the warning sound for the closing operation of the window that is difficult for the user to see corresponds to the window. Output from the speaker to the passenger in the rear seat. For this reason, there is no annoyance that the user of the driver's seat himself has to alert the passenger in the rear seat about the closing operation of the window.

  ADVANTAGE OF THE INVENTION According to this invention, after the notification sound for notifying window closing forgetting is emitted, it can suppress that a user feels troublesome when closing a window which has been opened.

OPEN!” Are output in order. The electronic control device 21 at this time functions as a control unit for outputting the above-described notification sound from the speaker 16 in order. Note that the order in which the notification sounds are output is determined as follows, for example.

  That is, if all the windows 7 are in an open state, the speaker 16 of the driver's seat 3, the speaker 16 of the rear seat 5, the speaker 16 of the rear seat 6, as shown by the two-dot chain line arrow in FIG. The notification sounds are output in the order of the speaker 16 of the seat 4. When there is a window 7 that is not open, the notification sound is output in the order in which the speaker 16 of the seat corresponding to the window 7 is skipped along the order.

  FIG. 3 is a flowchart showing an execution procedure of alarm processing for outputting the notification sound from the speaker 16. This alarm process is started through the electronic control device 21 when the ignition switch 10 is turned off, that is, when an off signal is output from the ignition switch 10.

  The electronic control unit 21 acquires the opening degree of the window 7 for each window 7 as the process of step 101 (S101) in the alarm process. The opening degree of the window 7 acquired at this time is a value obtained based on a detection signal from the detection unit 9 of the motor 8 corresponding to the window 7.

  The electronic control unit 21 determines whether or not there is a window 7 in an open state based on the acquired opening degree of each window 7 as processing of S102. If there is no window 7 that is open, the electronic control unit 21 ends this alarm processing. On the other hand, if there is a window 7 in an open state, the process proceeds to S103.

  As a process of S103, the electronic control device 21 confirms that the window 7 is in the open state in the order indicated by the two-dot chain line arrow in FIG. 1 from the speaker 16 of the seat corresponding to the open window 7. The above-mentioned notification sound for is output. Thereafter, the electronic control unit 21 ends this alarm process.
