Therefore, the present invention automatically closes the window when the ignition key is off, so that all the windows are automatically closed before the driver leaves the vehicle, thereby ensuring more secure security and preventing theft.

Description

Device for automatic closing of windows when the ignition key is off and its method.

The present invention relates to an apparatus and a method for automatically closing a window when the ignition key is turned off, and more particularly, to an apparatus and a method for automatically closing a window when the ignition key is turned off when the ignition key is turned off while the driver is in the riding state. will be.

The automatic opening and closing control device for a car window disclosed in the prior art Utility Model Publication No. 95-25265 automatically closes the open window when the driver closes the door after getting off, when the driver unloads the window without inadvertently closing it. By opening the closed window through the remote control, it is convenient to use the window electric opening and closing system, and copes with the case that the driver opens the window in an unavoidable manner, thereby maintaining security, maintaining safety and preventing theft. It is a device that can be used.

The conventional vehicle window automatic opening and closing control device locks the door after the driver gets off, and the window is automatically closed to prevent security maintenance and theft. However, since the window is actually closed for several seconds, the window is closed only after the driver leaves the vehicle. Since it was completely closed, there was a concern that the window-up could be prevented between the closing of the window and the vehicle theft and security maintenance could be broken.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic window closing device and a method for automatically closing a window when the ignition key is turned off when the driver turns off the ignition key in order to solve the problems of the prior art.

In order to achieve the above object, the device of the present invention includes an ignition switch for inserting a ignition key to start an electric device and start an engine; A battery for supplying electricity to all the electric devices in the vehicle by the electric device ignition of the ignition switch; A window opening / closing motor which receives electricity from the battery and is driven by a predetermined control signal to open and close the window; And a system control unit which detects a position of a start key of the ignition switch and outputs a signal corresponding thereto to the window opening / closing motor to control opening and closing of the window.

In addition, the operation of the automatic window closing device according to the present invention, the start key position detection step of detecting the position of the start key of the ignition switch; A window checking step of checking whether there is an open window when the starting key is in the off position in the starting key position detecting step; And a window closing step of closing the open window by applying a predetermined control signal to the window opening and closing motor if there is an open window in the window checking step.

1 is a block diagram showing a window automatic closing device when the ignition key off according to the present invention.

Figure 2 is a flow chart showing the operation of the automatic window closing device when the start key off in accordance with the present invention.

Hereinafter, with reference to the accompanying drawings will be described in more detail the present invention.

1 is a block diagram of an automatic window closing device for starting key off according to the present invention, and includes an ignition switch 10, a battery 20, a window opening and closing motor 30, and a system control unit 40. .

On the other hand, the ignition switch 10 has a lock position (B) for plugging and unplugging the ignition key, an off position (I) for turning off the engine but not pulling the ignition key, and an on position (II) for operating all electric devices. And a starting position (III) for starting the engine.

In addition, the battery 20 is configured to supply power to all electric devices in the vehicle by ignition of the ignition switch, and the window opening and closing motor 30 is supplied with the power of the battery 20 and by a predetermined control signal. It is configured to open and close windows.

In addition, the system control unit 40 is configured to detect the position of the start key of the ignition switch 10 and output a signal corresponding thereto to the window opening and closing motor 30 to control the opening and closing of the window.

FIG. 2 is a flowchart illustrating an operation process of a window closing device automatically when the start key is turned off according to the present invention. Referring to FIG. 1 and FIG.

First, the system controller 40 detects the position of the ignition key of the ignition switch 10 (S1), and in the process of detecting the position of the ignition key, the ignition key is in the off position (I) or the lock position (B). If so, the system control unit 40 checks whether there is an open window (S2).

If there is an open window in the process of checking whether there is an open window, the system control unit 40 closes the open window by applying a predetermined control signal to the window opening and closing motor 30 (S3).

As described above, when the ignition switch is turned off, the radio antenna is folded and the wiper is stopped, and the automatic window closing device according to the present invention automatically closes the open window so that all windows are closed before the driver leaves the vehicle. More secure security and theft protection can be achieved.

Therefore, as described above, the present invention has the effect of maintaining more secure security and preventing theft by closing all windows before the driver leaves the vehicle by automatically closing the window when the ignition key is off.
