JP2527502Y2 - Control device for power window for back door - Google Patents

Description

[Detailed description of the invention]

[0001]

The present invention is applied to an automobile having a power window on a back door.

[0002]

2. Description of the Related Art An operation switch for a power window is provided in a driver's seat to control the entire window, and each door is provided with a switch for operating only the window.

In such a vehicle, the driver and the passenger near the window may simultaneously operate the operation switch of the same window in the opposite direction. When such an inconsistent command is sent to one device, for example, when one of them issues an opening direction instruction and the other gives a closing direction instruction, the current supply to the window driving device is prohibited and the window A device that stops operation is known.

In a vehicle equipped with a power window on the back door, a window switch that can be operated by an engine key from the outside is provided on the back door.

[0005]

[Problems to be Solved by the Invention] In a vehicle having a power window on a back door as described above, a driver's seat and an engine key holder outside the back door simultaneously indicate directions in different directions. If you issue
Since neither of them can confirm the appearance of the other party well, it may be determined that the window circuit is faulty.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problem and to provide a control apparatus for a power window for a back door which does not cause confusion in opening and closing instructions of the power window.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a control apparatus for a power window for a back door in which operation switches for giving an instruction to open or close the power window of the back door of an automobile are provided at two places. When the operation switches arranged at the two positions are simultaneously operated in the opening direction and the closing direction, a means for generating an audible alarm is provided.

[0008]

[Action] If instructions are given contradicting each other at the same time,
A sound is generated so that the operator can immediately recognize the error.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a layout diagram of an embodiment of the present invention, and FIG. 2 is a control block configuration diagram of the same.

In FIG. 1, a power window PW is provided in the back door BD which is opened as shown by a broken line. It can be activated when detected by the left and right door locks LR and RR. This includes a first window switch PS1 provided in the driver's seat and a second window switch PS2 provided in the back door BD and operated from outside by an engine key.
And the drive current is supplied to the motor M1.

Power is sent from the battery BA to the relay box CRB shown in FIG. 2 via the breaker CB. According to an instruction of either the first or second window switch, the control unit CP in the relay box CRB causes the winding R3 or R3 of the relay.
Activating the relay contact r3 or r4
Operates, and the motor M1 raises or lowers the power window PW.

The feature of the present invention is shown in FIG.
As shown in the figure, the relay box CRB includes a buzzer BZ as a means for generating an audible alarm, and the control unit CP is operated when the window switches PS1 and PS2 arranged at two positions are simultaneously operated in the opening direction and the closing direction. A logic circuit (see FIG. 3) for giving a sound signal to the buzzer BZ is provided.

That is, when the second window switch PS2 disposed on the back door BD is operated to open the power window PW from outside the vehicle, the first window switch PS1 is simultaneously operated from the driver's seat to open the power window PW. In this case, since the opening instruction is issued, the winding R4 of the relay operates as shown in the control block diagram of FIG. 2, the contact r4 is switched, and the window is opened. However, when the power window PW is half-opened in advance, the window is closed in the driver's seat and the window is opened from outside the vehicle, and when inconsistent instructions are given, the buzzer BZ is sounded without switching the relay.

[0015]

[Effects of the Invention] As described above, according to the present invention,
When two contradictory instruction signals are simultaneously input from the two operation switches, an audible alarm is generated, so that the operator can notice an error.
