Description

Power window device for vehicle and its control method {Method and device of power window for vehicle}

The present invention relates to a vehicle power window device and a control method thereof, and more particularly, a vehicle power window configured to automatically open an initial window glass when the switch is in an on state, and to close the window glass by turning off the switch. An apparatus and a control method thereof are provided.

The interior space created by the center body, the cap, etc. is opened and closed by the door, and the door is formed with a window so that the interior space can be opened without opening or closing the entire door.

In addition, the door glass that opens and closes the window may be manually opened, and may be configured as a power window that can be opened automatically by operating a switch. In particular, such a power window may have rotational power as shown in FIGS. 1 and 2. Of the plurality of doors 10, 12, 14, 16 by the rotational force of the motors 2, 4, 6, 8, and the motors 2, 4, 6, 8, In order to control the driving state of each link unit 32 and the motors 2, 4, 6 and 8, which raise and lower the door glasses 18, 20, 22 and 24, respectively or simultaneously. It consists of a switch assembly to be operated.

The plurality of motors (2), (4), (6) and (8) are configured to rotate forward and reverse as the current of the power source is applied, respectively, so that the front doors 10, 12 and the rear doors 14 (left and right) ( Each is built in 16).

Moreover, the said link part 32 is each movable member 58 fixed to the predetermined site | part of the multiple wire 50 which is driven by the rotational force of the multiple motors 2, 4, 6, and 8, respectively, The movable members 58 are coupled to each of the guides 66 so as to be lifted and lowered to the movable members 58 to the lower ends of the respective door glasses 18, 20, 22, and 24. consist of.

On the other hand, the switch assembly is the main switch 34, 36, 38, 40 disposed in the position between the driver's seat and the passenger seat, and the sub-switch 42 located in the rear door 14, 16 of the left and right It consists of 44, and is electrically connected with the ignition key switch 70 so that electric current may be supplied from the power supply 72 when the ignition key switch 70 is turned on.

According to this configuration, the main switch 34, 36, 38, 40 or the sub switch 42 (with the ignition key switch 70 turned on by the start key and the remote start signal as shown in FIG. 2). When the respective 44 are selectively turned on, current is applied from the power supply 72 to each of the motors 2, 4, 6, and 8 to rotate the motors 2, 4, 6, and 8 forward.

Motor (2) (4) (6) (8) is reversely rotated to drive each wire (50) in the other direction by the rotational force of such motor (2) (4) (6) (8). As a result, the movable member 58 and the door glasses 18, 20, 22, and 24 are raised to close (see FIG. 1).

However, in the conventional power window device as described above, the door glass can be opened only when the main switch or a plurality of sub-switches are first put in the interior of the vehicle, so that the door glass can be opened to the operator when the temperature in the interior is high. There was a disadvantage that the pain caused by the heat and inconvenience caused by manual operation of the switch.

In addition, if the vehicle is driven while the door glass is open and it rains at this time, the occupants must close all of the door glasses, so that there is another disadvantage that the driving safety is particularly disturbed when the occupant is one driver.

The present invention has been made to solve the above-mentioned disadvantages, the object of the present invention is to open the door glass automatically in response to the temperature condition in the vehicle interior, and can open the door glass, rainy conditions It is to provide a vehicle power window device that can detect and automatically close the door glass and a control method thereof.
