Is for illuminating each switch 22, 23, 24.

Then, when the lowering switch 22 is operated,
When the movable contact 25 is connected to the fixed contact 26 and turned on, the H (high) level voltage is applied to the door ECU 21 as a down command signal. The door ECU 21 controls the drive circuit 30 to rotate the drive motor M while the down command signal is applied. As a result, a wire type or arm type regulator (not shown) is driven by the drive motor M to lower the window glass.

When the movable switch 25 is connected to the fixed contact 27 and turned on by operating the raising switch 23, an H level voltage is applied to the door ECU 21 as a raising command signal. The door ECU 21 controls the drive circuit 30 while the up command signal is applied, and reverses the drive motor M in the opposite manner to the case of the down movement. As a result, a wire type or arm type regulator (not shown) is driven by the drive motor M to raise the window glass.

Even if 5 is not operated, the movable contact 25 or between the fixed contact 25a on the power supply side and the fixed contact 26 and between the movable contact 25 or the fixed contact 25a on the power supply side and the fixed contact 27 simultaneously leaks. There is. In such a case, since the movable contact 25 is not actually operated, the door ECU 21 controls when the ascending command signal and the descending command signal are simultaneously applied from both the fixed contacts 26 and 27. In accordance with the program, no response is made to any signal, that is, the drive motor M is not driven via the drive circuit 30.

As described above, the power window switch circuit 20 provided with the lowering switch 22 and the raising switch 23.
When the contacts of the switches 22 and 23 are short-circuited, the drive motor M is not driven either upward or downward.

That is, neither the ascending or descending drive of the window glass is performed.

The power window switch circuit 20,
The door ECU 21, the drive circuit 30, and the drive motor 30 constitute the power window device 1. A water immersion detector 40 is connected to the door ECU 21.
The water immersion detector 40 is for detecting the water intrusion of the vehicle when the vehicle is inundated, and is arranged in a living room, an engine room, a trunk room or the like of the vehicle which is not wet with normal rainwater. The water immersion detector 40 is the first fixed contact 4

And the movable contact 25 or between the fixed contact 25a on the power supply side and the fixed contact 27 simultaneously leaks. In this state, the down command signal and the up command signal are input to the door ECU 21 from both the down terminal D and the up terminal U.

However, when the movable contact 25 is not actually operated, the door ECU 21 follows the flow chart of the control program described later even if the rising instruction signal and the descending instruction signal are simultaneously applied from both fixed contacts. , Does not respond to any signal, that is, the drive circuit 3
The drive motor M is not driven via 0.

When the lowering switch 22 is turned on in this state, the lowering switch 22 and the first ground switch 3 are turned on.
3 are simultaneously turned on, and the fixed contact 27 of the rising switch circuit is grounded.

Accordingly, although the contact between the contacts of the rising switch 23 is leaked, the rising switch circuit is grounded, so that the rising switch circuit is practically turned off and L
(Low) level voltage goes up through the terminal U to the door EC
Input to U21. On the other hand, the lowering switch 22 is turned on by an on operation, and the H
The level voltage is applied to the door ECU 21 as an operation detection signal.

On the other hand, when the raising switch 23 is turned on, the raising switch 23 and the second ground switch 35 are turned on.
Are simultaneously turned on, and the fixed contact 26 of the down switch circuit is grounded.

Therefore, although the contact between the descending switch 22 is leaked, since the descending switch circuit is grounded, the descending switch circuit is practically turned off and L
The (low) level voltage is applied to the door EC via the down terminal D.
It is applied to U21. On the other hand, the raising switch 23 is turned on by an on operation, and the up switch 23 is turned to H
The level voltage is applied to the door ECU 21 as an operation detection signal.

The operation of the power window device 1 having the power window switch circuit 20 for performing the above operation will be described with reference to the flowchart of FIG. FIG. 2 is a flowchart of window glass ascending / descending processing executed by the door ECU 21 when the descending switch 22 and the ascending switch 23, which are manual switches, are operated. This process is executed on a regular basis.

Upon entering this processing, the flood flag F is read in step 100. The flood flag F indicates that the flood detector 40 has flooded and the power source side fixed contact 43 and the fixed contact 41.
And the fixed contact 42 on the power source side and the fixed contact 42 both leak, and when a voltage of H (high) level is applied to the door ECU 21 from both fixed contacts 41 and 42,
Set to "1". Therefore, when the water infiltration detector 40 is not inundated, that is, when the vehicle is not inundated, it is reset to "0".

In step 110, the raising switch 2
It is determined whether or not 3 is turned on. That is, it is determined whether or not the H (high) level increase command signal is input from the up terminal U to the door ECU 21. If the rising command signal is not input, step 15
Move to 0.

When the ascending command signal is input in step 110, it is determined in step 120 whether or not the descending switch 22 is turned on. That is, it is determined whether or not the down command signal of H (high level) is input from the down terminal D to the door ECU 21. If the descending command signal is input, it is determined in step 110 that the ascending command signal has already been input.
2 and 23 are not manually operated, and it is assumed that the contacts of both switches 22 and 23 are leaking, and this processing routine is temporarily terminated.

In step 120, when the descending command signal is not input, the process proceeds to step 130, and it is determined whether or not the water immersion flag F is reset to "0". That is, it is determined whether or not the vehicle is currently flooded. If the waterlogging flag F is reset to "0", it is determined that the vehicle is not flooded, the process proceeds to step 140, the drive circuit 30 is controlled to drive the window glass upward, and this process is performed. Ends once.

If the water-immersion flag F is not reset to "0" but is set to "1", it is determined that the vehicle is in water and the routine proceeds to step 160 where the drive circuit 30 is operated. Is controlled to drive the window glass downward, and this process is once ended.

Further, the steps 110 to 15
When it is shifted to 0, in step 150, it is determined whether or not the lowering switch 22 is turned on. That is, the down terminals D to H for the door ECU 21
It is determined whether or not a (high level) descending command signal is input. When the descending command signal is not input, it is assumed that both switches 22 and 23 are not operated, and this processing routine is temporarily terminated.

If the descending command signal is input in step 150, the process proceeds to step 160, the driving circuit 30 is controlled to drive the window glass downward, and this process is once ended.

In the processing of the above flow chart, the case where the vehicle is flooded and the case where it is not flooded are divided into
explain. If the car is not flooded, in normal case,
When the raising switch 23 is turned on, step 100,
Each processing of 110, 120, 130 is performed, and step 1
At 40, the drive motor M is driven upward.

When the lowering switch 22 is turned on,
Each processing of steps 100, 110, 150 is performed, and the driving motor M is driven to descend in step 160. When the vehicle is flooded, the respective contacts of the lowering switch 22 and the raising switch 23 of the power window switch circuit 120 are in a leaking state, and the flooding detector 40 detects the flooding, when the raising switch 23 is turned on, Each processing of steps 100, 110, 120 and 130 is performed, and the driving motor M is driven to descend in step 160.

Even when the vehicle is flooded, when the descent switch 23 is turned on, the processes of steps 100, 110 and 150 are performed as in the case where the vehicle is not flooded, and the driving motor M is descent driven at step 160. To do.

When the vehicle is not submerged, that is, when the submersion detector 40 does not detect the submergence, rainwater, drinking water, etc. enter the power window switch circuit 20 and the switches 22 and 23 are turned off. If both switches 22 and 23 are not actually turned on while both are leaking, steps 100, 110 and 12 are performed.
Each processing of 0 is performed, and the routine is once ended as it is. Therefore, unless the switches 22 and 23 are turned on, the window glass does not move up or down.

Now, according to this embodiment, the following operational effects are obtained. (1) In the present embodiment, even when the power window switch circuit 20 is wet with an electrolyte such as water and leaks between the contacts of the descending switch 22 and the ascending switch 23,
When the down switch 22 is turned on, the up switch 23
The rising switch circuit including the above is grounded, and the rising switch is practically turned off even if there is a leak between the contacts of the rising switch.

As a result, even if the power window switch circuit 20 gets wet with water or the like due to flooding, the lowering switch 22
By turning on, the window glass can be lowered. (2) In the present embodiment, even when the power window switch circuit 20 is wet with water due to flooding and there is a leak between the contacts of the descending switch 22 and the ascending switch 23,
When the up switch 23 is turned on, the down switch 22
Even if there is a leak between the contacts of the down switch 22, the down switch circuit including the down switch circuit is grounded.
2 is turned off. And the flood detector 4
When the water immersion detection of 0 is performed, even if the power window switch circuit 20 gets wet with water or the like, the window glass can be lowered by turning on the raising switch 23.

Further, in the case where the window glass is not flooded, the window glass can be raised by turning on the raising switch 23 in the same manner as usual. (Second Embodiment) Next, a second embodiment will be described with reference to FIG. In the second embodiment, the hardware configuration is the same as that of the first embodiment, and the door ECU 21
The control program executed by is different.

FIG. 3 is a flowchart of window glass ascending / descending processing executed by the door ECU 21 when the descending switch 22 and the ascending switch 23, which are manual switches, are operated. This process is executed on a regular basis.

Upon entering this processing, the flood flag F is read in step 200. The flooding flag F is set and reset in the same manner as in the first embodiment. Next, in step 210, it is determined whether or not the inundation flag F is reset to "0". That is, it is determined whether or not the vehicle is currently flooded. If the flooding flag F is reset to "0", it is determined that the vehicle is not flooded, and step 220
Move to.

In step 220, it is determined whether or not the raising switch 23 has been turned on. That is, the door EC
It is determined whether or not the H (high level) rising command signal is input to the U21 from the up terminal U. If the rise command signal is not input, the process proceeds to step 250. When the rising command signal is input, it is determined in step 230 whether the lowering switch 22 is turned on. That is, the door ECU 21
It is determined whether or not a down command signal of H (high level) is input from the down terminal D. If the down command signal is input, in the previous step 220,
Since it is determined that the rising command signal has already been input, both switches 22 and 23 are not actually manually operated, and the contacts of both switches 22 and 23 are leaking for some reason. Then, this processing routine is temporarily terminated.

When the lowering command signal is not input in step 230, it is determined that only the raising switch 23 is normally operated, and the process proceeds to step 240 to control the drive circuit 30 to raise the window glass. It is driven, and this processing is once ended.

In addition, the above steps 220 to 25
If it has shifted to 0, in step 250, it is determined whether or not the lowering switch 22 is turned on. That is, it is determined whether or not the down command signal of H (high) level is input from the down terminal D to the door ECU 21. If the down command signal is not input, it is assumed that both switches 22 and 23 are not operated, and this processing routine is once ended.

If the descending command signal is input in step 250, the process proceeds to step 260, the drive circuit 30 is controlled to drive the window glass downward, and this process is once terminated.

If the flooding flag F is set to "1" in step 210, it is determined that the automobile is flooded, and the down switch 22 or the up switch 23 is turned on in step 270. Determine whether or not.

The determination in step 270 is that the up terminal U,
This is performed depending on whether or not only one of the down terminals D has an H (high) level voltage applied to the door ECU 21 as an operation detection signal.

If the H (high) level voltage is applied to the door ECU 21 as the operation detection signal from only one of the up terminal U and the down terminal D, the process proceeds to step 260 and the drive circuit 30 is operated. The window glass is controlled to be driven downward, and this process is once ended.

If the H (high) level voltage from only one of the up terminal U and the down terminal D is not applied to the door ECU 21 as the operation detection signal, this processing routine is temporarily terminated.

Incidentally, the case where the voltage of H (high) level from only one of the up terminal U and the down terminal D is not applied to the door ECU 21 as the operation detection signal is
There are the following two cases.

1) H (high) from both terminals U and D
When a level voltage is applied, both switches 22,
23 is in a leaking state and both switches 22.23
When both are not turned on.

2) H (low) from both terminals U and D
When a level voltage is applied, both switches 22,
When the contacts of No. 23 are not leaked and both switches 22.23 are not turned on.

In any of the above 1) and 2), since the lowering switch 22 and the raising switch 23 are not operated, the drive motor M is not driven.
Now, according to the present embodiment, the following operational effects are exhibited.

(1) In this embodiment, the water-immersion flag F is set to "1" and either the lowering switch 22 or the uppering switch 23 is operated to set the H (high) level as the operation detection signal. The glass window is driven downward on the condition that the signal is applied to the door ECU 21. As a result, even if the power window switch circuit 20 gets wet with water or the like due to flooding, the window glass can be lowered by turning on either the lowering switch 22 or the raising switch 23.
