Utility Model Publication No. 58-43536, Utility Model Application No. 58-8946
1 Publication and Utility Model Publication No. 1986-1006). Also,
Such a side window wiper device requires a washer device that ejects washer fluid to clean the side window glass in the same way as a normal wiper device that wipes the front window glass. As for the device, Utility Model Application No. 59-179153 and Utility Model Application No. 61-64
There is one described in Publication No. 068. Note that a normal wiper device for wiping the front window glass is combined with a washer device to prevent the washer fluid sprayed onto the glass surface by the washer motor from interfering with the wiper blade while the wiper device is operating. It has been proposed to provide a switching mechanism for stopping the washer motor and interrupting the injection of washer fluid (Japanese Utility Model Publication No. 57-457).

[Problem to be solved by the invention]

However, there has been no technology that allows the side window wiper device that wipes the side window glass to operate in conjunction with the washer device that sprays washer fluid onto the side window glass. When the wiper device is operating, the wiper blade and the washer fluid interfere with each other, causing the washer fluid to splash onto the surface of the side mirror or the part of the side window glass that cannot be wiped off with the wiper, staining the side mirror and side window glass. Occur.
The present invention has been made to solve the above problems, and provides a side window wiper washer device in which the wiper blade and the washer liquid do not interfere with each other during operation of the wiper device and do not stain the surfaces of side mirrors, etc. With the goal.

[Means to solve the problem]

To achieve the above object, the present invention provides a wiper device that wipes a side window glass of a vehicle by reversing the operating direction of a wiper blade at a reversal position and reciprocating the wiper blade, and a wiper device that wipes a side window glass of a vehicle by reciprocating the operating direction of the wiper blade at a reverse position, and The washer device includes a washer device that spouts liquid, and a control means that enables the washer device to operate when the wiper blade reaches the inverted position.

[Effect]

The wiper device of the present invention wipes the wiping range of the side window glass of a vehicle by reversing the operating direction of the wiper blade at the reverse position and causing it to reciprocate. The washer device squirts washer liquid into the wiping range of the side window glass.

The control means then enables activation of the washer device when the wiper blade reaches the reversal position. Therefore, if an activation signal for activating the washer device is output when the wiper blade reaches the reverse position, the washer fluid will be ejected. At this time, the wiper blade is located in the reverse position, that is, at the boundary between the wiping range and the non-wiping range, so that the wiper blade and washer fluid do not interfere with each other, and the non-wiping range of the side mirror surface and side window glass is prevented. This prevents washer fluid from adhering to the

A limit switch 82R and a limit switch 82L are respectively connected to detect whether or not the window glass on the Pa side has reached the proper raised position. The ignition switch 78 is grounded via a fusible link and a batch 'JB, and outputs an on signal when the ACC contact and the IG contact are turned on. The configuration is such that power is supplied from the batch IJB to each of the side window wiper washer devices via the ignition switch 78. The washer switch 80 is configured as a push switch and outputs an on signal only when pushed by the operator.

The limit switch 82R and limit switch 82L are used when the window is completely closed by the window glass or when the window glass is slightly opened to listen to external sounds (the window glass has reached the proper raised position). outputs an on signal when
Outputs an off signal when the window exists at a position other than these positions.

The control circuit 70 includes a Dr.
One end of the side power window motor 84R and the Pa side power window motor 84L are connected to each other.

When the switch of the Dr side power window device is operated, current is supplied from the power window drive circuit 86R to the power window motor 84R, so by detecting this current it is possible to detect whether or not the operation of the power window device has started. Can be done. Similarly, the operating state of the Pa-side power window device can also be detected from the current flowing from the drive circuit 86L to the power window motor 84L.

Next, a control routine for the side window wiper washer device by the microcomputer of the control circuit will be described. In addition, although the following description uses numerical values that do not hinder the present invention, the present invention is not limited to these numerical values.

Figure 7 shows that when the ignition switch is turned on,
That is, this shows a main routine that is executed when power is supplied to the side window wiper washer device, etc. In step 98, the washer drive circuit 94
In step 100, the Dr side and Pa
It is determined whether both side wiper blades are located at the stop position A. When both the wiper blades on the Dr side and the Pa side are located at the stop position A, the process directly advances to step 111, sets flag F, cancels the prohibition of operation of the washer drive circuit 94, and enables the washer device. . - If the wiper blade on the Dr side or Pa side is not located at the stop position A, step 10
After determining in step 2 which side window wiper device the wiper blade is not located at the stop position A, in step 104 it is determined in which position the wiper blade of this wiper device is currently located. If it is determined that the wiper blade is located in the area a shown in FIG. 5, the process directly proceeds to step 111, and if it is determined that the wiper blade is located in the area or next to the lower inverted position, the process proceeds to step 111. After performing an operation to move the wiper blade to the stop position A (hereinafter referred to as a rise-down operation) in step 110, the process proceeds to step 111. When it is determined that the wiper blade is located in the upper inverted position C or region d of the wiping range c1, an operation (hereinafter referred to as inverted operation) is performed to move the wiper blade toward the lower inverted position B in step 106. After that, in step 107, the count value KB is set to 0 (in order to prevent reversing operations not caused by the washer switch from being counted), and in step 108, a rise-down operation is performed, and the process proceeds to step 111.

As a result of the above, when the ignition switch is turned on and the wiper blade is not in stop position A or downward overrun area a, after the wiper device is driven and the wiper blade is stored in stop position A, , flag F is set to enable the washer device to operate.

In the next step 112, it is determined whether or not the washer switch 80 is turned on. If the washer switch 80 is turned on, in step 114, D is determined based on the on/off states of the limit switches 82R and 82L.
It is determined whether both the r-side and Pa-side window glasses are located in the proper raised position, and if there is a window glass that is not located in the proper raised position (window glass that is opened), In step 115, flag F is set to prohibit the operation of the washer device, and in step 116, it is determined which side the window glass is opened, and in step 118, the side window on the side window glass that is opened is set. To disable the wiper device so that it cannot operate.

The process then proceeds to step 130 to operate the side window wiper device on the side where the window glass is in the proper raised position. On the other hand, if both window glasses are in the proper raised position, step 12
After operating the washer drive circuit 94 at step 122, the washer drive circuit is operated for a predetermined time t.
. (See FIG. 14 (7)) It is determined whether the predetermined time t0 has elapsed or not, and if the predetermined time t0 has elapsed, the operation of the washer drive circuit 94 is stopped in step 128, and then the process proceeds to step 130 in order to operate the wiper device. move on. On the other hand, the predetermined time t. If the washer switch has not elapsed, it is determined in step 124 whether the washer switch has been turned off, and if it has been turned off, it is determined in step 126 whether the predetermined time 1+ (see FIG. 14 (1) to (6)) has elapsed. death,
If it is determined that the time has elapsed, the operation of the washer drive circuit is stopped in step 128, and the process proceeds to step 130.

In step 130, an operation is performed to move the wiper blade from the stop position A toward the epithelial rotation position C (hereinafter referred to as normal rotation operation), and after a reversal operation is performed in step 132, a count indicating the number of times of the reversal operation is performed in step 134. It is determined whether the value KB is 3 or more, and if it is less than 3, the forward rotation operation and reverse rotation operation are repeated, and if it is 3 or more, the count value KB is reset in step 136, and then the rise down operation is performed in step 138. Do this.

As a result of the above, when the washer switch is turned on, if both window glasses are in the proper position, the washer device is activated, and after a predetermined time (after to or after t1 from the washer switch off), the washer device operation is stopped.
At the same time, the wiper device is activated. Also, if there is an open window, the washer device will not be activated even if the washer switch is turned on, and the washer device will not be activated on the side where the window is closed (the side where the window glass is in the proper raised position). Only the side window wiper device is operated and returned to the stop position A after a predetermined number of wiping operations.

Next, details of the forward rotation operation, reverse operation, and rise down operation will be explained with reference to FIGS. 8, 9, and 10.

Figure 8 shows the routine of normal rotation operation, step 1.
At step 40, an actuation signal for moving the wiper blade in the epithelial translocation direction C is output, and at step 142, after outputting this actuation signal, a predetermined time T3 (for example,
2 seconds) has elapsed. If the predetermined time T3 has not elapsed, it is determined in step 144 whether the wiper blade has reached the top rolling position C based on the output of the position detection sensor 76. When the wiper blade does not reach the upper rotation position C, the operation signal is continued to be output, and when the wiper blade reaches the upper rotation position C, the output of the operation signal is stopped in step 146 and the wiper blade is operated. After stopping, in step 148, a count value KC (initial value is 0) that counts the number of times the wiper blade reaches the upper pressure rotation position C is incremented.

In the next step 150, it is determined whether the count value KC has become 3 or more, and if it has become 3 or more, step 1
In step 51, it is determined whether the 7 lag F is set and the washer switch continues to be on (or not turned on again), and if this determination is affirmative, the washer device is operated for a predetermined time t2 in step 152. After outputting the washer activation signal, it is determined in step 153 whether or not a predetermined time T2 has elapsed, and if so, the process proceeds to the next step. On the other hand, the count value KC is 3
If less than, step 154
1, it is determined whether the flag F is set and the washer switch continues to be in the on state.
)) After outputting a signal for activating the washer device, it is determined in step 156 whether or not a predetermined time T1 has elapsed, and if so, the process proceeds to the next step.

As a result of the above, if both side window glasses are in the proper position and the washer switch is on, washer fluid is injected for a predetermined time t2 at the upper pressure rotation position (14th
(Fig. (7)), when returning to the stop position after performing the wiping operation a predetermined number of times, it is stopped for a longer time T2 than the normal time at the upper pressure rotation position immediately before returning to the stop position.

On the other hand, when it is determined in step 142 that the predetermined time T3 has elapsed, that is, when the wiper blade does not reach the upper rotation position C even though the operation signal for normal rotation operation is continuously output, It is determined that the wiper blade will not move due to an obstacle, etc., and the process proceeds to the next step.

As a result, when the upper pressure rotation position is not reached, the reversal operation described below is forcibly executed.

FIG. 9 shows a routine for performing a reversing operation. In step 160, an operating signal is output for moving the wiper blade from the upper pressure rotation position C to the lower reversing position, and in step 162, an operating signal is output. It is determined whether a predetermined time T has elapsed since then. If it is determined that the predetermined time T has not elapsed, it is determined in step 164 whether the wiper blade has reached the lower reversal position B, and if the wiper blade has not reached the lower reversal position RB, then in step 160 to continue outputting the activation signal. When it is determined that the wiper blade has reached the lower inversion position B, the operation of the wiper blade is stopped in step 166, and a count value KB for counting the number of times the wiper blade has reached the lower inversion position B is incremented in step 168. After that, in step 170, it is determined whether the count value KB has become 3 or more, thereby determining whether the lower reversal position has been reached a predetermined number of times. When the count value KB is 3 or more, the process proceeds to the next step without activating the washer device, and when the count value KB is less than 3, a flag F is set in step 169 and it is determined whether the washer switch continues to be on. If this judgment is affirmative, in step 171 the washer drive circuit is operated for a predetermined period of time 1+ (
(See FIG. 14 (7)) After outputting the washer activation signal for activation, in step 172
, wait until , and proceed to the next step. On the other hand, if it is determined in step 162 that the wiper blade has not reached the lower reversal position even though the actuation signal is continuously output, the process directly proceeds to the next step.

FIG. 10 shows a routine for performing a rise-down operation. In step 180, an operating signal for moving the wiper blade from the lower reversal position B to the stop position A is output, and in step 182, a predetermined period of time (for example, If the predetermined time has not elapsed, it is determined in step 184 whether the wiper blade has reached the stop position A. When it is determined that the wiper blade has reached the stop position A, the operation of the side window wiper device is stopped in step 186, and when it is determined that the wiper blade has not reached the stop position A, the operation returns to step 180. Continue outputting the signal. On the other hand, if it is determined in step 182 that the predetermined time has elapsed, it is determined that the wiper blade is stopped at a position other than stop position A due to an obstacle or the like, and the operation is stopped in step 186.

FIG. 11 shows disabling signals (cancellation signals) for disabling the operation of the side window wiper washer device, such as a stop signal for stopping the side window wiper washer device and a power window drive signal for driving the power window device. This shows the interrupt routine that will be interrupted when it occurs. The above stop signal is
A stop switch may be provided, and the signal may be generated by operating the switch, and the signal generated when the washer switch 80 is pressed while the side window wiper device is operating by using the washer switch 80 described above (side window washer device It is also possible to use an on-signal that is generated again after a series of operations is completed as a stop signal. The routine shown in FIG. 11 will be explained. When a cancel signal is generated, this routine is executed, and it is determined in step 188 whether or not the washer device is operating. If it is operating, the operation of the washer device is stopped in step 189, and then the process proceeds to step 190. As a result, when the window is opened while the washer device is in operation, the operation of the washer device can be stopped. Further, if the signal when the washer switch is pressed again is used as a cancel signal, the inversion operation is performed as it is, so even if the washer switch is pressed again, the washer IT will not be activated. In the next step 190, it is determined whether the wiper blade is performing a reverse rotation operation or a forward rotation operation (wiping operation). If the normal rotation operation or the reverse rotation operation is not being executed, the process returns to the main routine, and if the reverse rotation operation or the normal rotation operation is being executed, the wiper blade is moved from the wiping range to the lower reversal position in step 191. After outputting a reversal activation signal and determining in step 192 whether or not the lower reversal position has been reached, a rise-down operation is executed in step 194.

As a result of the above, when the washer switch is turned on again or the window is opened while the wiper device is in operation, the wiper blade can be immediately returned to the stop position.

Next, the operation of the wiper blade will be explained in more detail using the time chart shown in FIG.

In addition, in order to simplify the explanation, Fig. 12 (1) to (5)
In the following, only the operation of one wiper blade is shown.

Figure 12 (1) shows the normal operation of the wiper blade. When the washer switch is pressed once, the washer device is activated and then stopped, the wiper device is activated, and the wiper blade is moved from the stop position A. After performing the wiping operation a predetermined number of times, it is returned to the stop position A. The time it is stopped at the top pressure roll position C just before it is returned to the stop position A is longer than the normal stop time T1 (T+ <T
2).

By stopping the wiper blade at the upper pressure rotation position C for a predetermined time period of 12 or more immediately before storing the wiper blade, the raindrops and washer collected on the upper surface of the blade due to wiping can be removed as shown in FIG. 13 [1) and (2). The liquid flows along the wiper blade 54 in the direction of the wiper arm 52 as shown in FIG. 13 (3), and as a result, when the reversing operation is performed, raindrops and washer liquid collected by the wiper blade adhere to the window glass. There will be nothing to do (Figure 13 (4)).

Figure 12 (2) shows the washer switch 8 during the wiping operation.
This shows the operation when 0 is pressed and the actuation signal is output. When the actuation signal is output during the wiping operation, the wiper blade is immediately returned to the stop position WiA. Note that this first operation can also be performed by providing a switch for stopping the wiper device and generating a stop signal.

FIG. 12(3) shows the operation when the wiper blade does not reach the upper rolling position C due to an obstacle or the like. If the wiper blade does not reach the upper pressure rotation position C even after a period of time T has elapsed after starting the forward rotation operation, a reversal operation is performed, and when the reversal operation is performed a predetermined number of times, it returns to the stop position A.
will be returned to.

Figure 12 (4) shows the ignition switch (IGSW).
) shows the operation associated with turning on and off.

If the ignition switch is turned off during the wiping operation, the power supply to all the side window wiper washer devices is stopped, so the operation of the wiper blades is stopped. If you turn on the ignition switch in this condition,
Since the main routine shown in FIG. 7 is executed, the wiper blade is returned to the stop position A.

FIG. 12 (5) shows the operation when the power window device is activated during the wiping operation. When the power window device is activated during the wiping operation, the wiper blade is immediately returned to the rest position. As a result, even if the power window device performs an operation to open the window, the wiper blade will not intrude into the vehicle interior.

FIG. 12(6) shows the operation when the power window device on the Dr side or the Pa side is activated during the wiping operation. When the washer switch 80 is pushed - times with the Dr side and Pa side windows closed,
The side window wiper devices on the Dr side and Pa side are driven simultaneously. For example, if the power window device on the Dr side is activated in this state, the wiper blade of the side window wiper device on the Dr side is immediately returned to the stop position IA, but since the power window device on the Pa side is not activated, The wiper blade continues to operate.

FIG. 12 (7) shows the operation when the wiper switch 80 is pushed once with either the window on the Pa side or the Dr side open. The wiper blade on the side where the window is open is stopped at the stop position and does not operate, but the wiper blade on the side where the window is closed operates normally.

Further, with reference to FIG. 14, the operating states of the washer device and wiper device when the washer switch is operated will be described. FIG. 14 (1) shows the operating state when the washer switch is turned on for a short period of time. When the washer switch is turned on, the washer device is activated, and after the washer switch is turned off, a predetermined period of time 1. After the elapse of time, the operation of the washer device is stopped, and at the same time, the operation of the wiper device is started. Figure 14 (2) shows the operating state when the washer switch is turned on for a longer period than in Figure 14 (1), and in this case as well, the washer switch is turned on as in Figure 14 (1). Predetermined time after turning off 1. After the elapse of time, the washer device stops operating and the wiper device starts operating. Figure 14 (3) shows the situation when the washer switch is turned on with the window open; in this case, the washer device does not start operating, and the wiper device on the side where the window is open operates. is not started either. Figure 14 (4) shows the operating state when the window is opened while the washer is in operation; if the window is opened even though the washer switch is on, the washer will stop operating. . FIG. 14 (5) shows the operating state of the wiper device when the window is opened after the washer device and wiper device have been activated, and the same point in time as in FIG. 12 (6) is that the window is opened. The wiper device on the side where the window was opened is being operated in reverse. Figure 14 (6) shows the operating state of the wiper device when the washer switch is turned on again while the wiper device is operating after the washer device operation is stopped, and the on signal of the washer switch is the cancel signal. The wiper device is being operated in reverse. At this time, the washer device is not activated. Note that the above predetermined time 1. may be measured from the time the washer switch is turned on. FIG. 14 (7) shows an operating state when the washer switch is on for a very long time, and a predetermined time t has elapsed since the washer switch was turned on. After the elapsed time, the operation of the washer device is stopped and the operation of the wiper device is started, and when the wiper blade reaches the upper rotation position, the washer device is operated for a predetermined time t2, and the wiper blade reaches the lower rotation position. At times, the washer device is operated for a predetermined time t3. Note that at this time, the washer device is not operated in the lower reversal position of the final rotation.

In addition, although the example in which the washer device is operated at both the top rotation position and the bottom reverse position has been described above, the washer device may be operated only when the wiper blade reaches either one of the positions. Good too. In addition, even if one window is open, if the other window is closed, the wiper device on the side where the window is closed is activated.
The operation of both wiper devices may be prohibited even when one of the windows is opened.

Moreover, although an example in which the window glass is raised and lowered by a power window device has been described above, the present invention can also be applied to a door in which the window glass is raised and lowered by operating a handle.
