Description

  The present invention relates to an opening / closing member control device, and more particularly, to an opening / closing member control device capable of detecting that the opening / closing member is inhibited from moving due to the presence of foreign matter.

When opening / closing an opening / closing member such as a window glass provided on a door of a vehicle, a technique for detecting that the movement is blocked by a foreign object, specifically, sandwiched between the opening / closing member and its peripheral member Techniques for determining the presence or absence of foreign matter and the inclusion of foreign matter are already known. In such an opening / closing member control device, normally, when it is determined that there is a foreign object, the opening / closing operation of the opening / closing member is interrupted, and further, an operation opposite to the previous operation is performed to release the foreign object. It has become.
In addition, as the above control, for example, a threshold value is set for a measurement value that changes according to the load applied to the window (for example, the rotational speed of a motor that rotates to open and close the window glass). It is known to determine the presence or absence of foreign matter by comparing this threshold value with a measured value.

In order to determine this threshold value, a method based on the power supply voltage is often used, but when the power supply voltage changes due to aging of the battery or the ambient temperature, the threshold value itself is It will change according to such changes.
For this reason, in the technique shown in Patent Document 1, in order to set a threshold value when the power is turned on, the power supply voltage is sampled, and a change in the voltage value from the sampled power supply voltage value is monitored. The threshold value is corrected according to the above. Specifically, when the sampling voltage drops by more than the set voltage width (when the drop detection flag is set), it is configured to be switched to a correction operation mode in which the threshold value is corrected based on the voltage change amount. Has been.

JP 10-018709 A

However, in the technique of Patent Document 1, when the power supply voltage serving as a reference is high from the beginning, sampling starts with the high power supply voltage as a reference, so that the load applied when a foreign object is sandwiched increases. There was a concern. In other words, for example, when the window glass of the power window is caught, the motor rotation speed is detected and the motor is reversed. At this time, if the power supply voltage is high, the motor rotation speed is high. Therefore, there is a concern that the reverse load becomes high.
Therefore, development of a technique for avoiding such a situation has been demanded.

  Therefore, the present invention has been made in view of the above problems, and its purpose is to appropriately set this reference value on the premise that it is possible to detect the occurrence of movement inhibition of the opening and closing member based on the reference value. An object of the present invention is to provide an opening / closing member control device that can do this.

  According to the opening / closing member control device of the present invention, the subject is a motor that moves the opening / closing member provided in the door of the vehicle in the opening / closing direction, the opening / closing member, and the door based on a change in the operating state of the motor. And a control unit having a determination unit for determining the presence or absence of a foreign matter interposed between the peripheral members located around the open / close member and hindering the movement of the open / close member. The control unit includes a reference value switching unit that changes a reference value serving as an index for detecting that the movement of the opening / closing member is inhibited by the foreign matter, and the reference value switching unit includes: When the power supply voltage value is acquired, the power supply voltage value is compared with a predetermined voltage value, and the state where the power supply voltage value is larger than the predetermined voltage value continues for a predetermined time, the power supply voltage value To the value corresponding to It is solved by changing the reference value.

Thus, according to the opening / closing member control apparatus according to the present invention, the reference value switching means switches the reference value according to the power supply voltage value.
Specifically, when the acquired power supply voltage value is larger than a predetermined voltage value, the reference value is changed to a value corresponding to the acquired power supply voltage value. .
In other words, when the power supply voltage value becomes higher than a predetermined value, the rotational speed of the motor also increases, so the time from the start of movement inhibition until detection (for example, the motor rotational speed reaches the reference value) is delayed. As a result, the load or reverse load applied to the foreign object at the time of movement inhibition detection becomes too high. However, by setting a reference value according to the power supply voltage value as in the present invention, even when the power supply voltage is high, from the start of movement inhibition to detection (for example, the motor rotation speed reaches the reference value). Since this time can be made equal to the normal time, this situation can be avoided. Therefore, it is possible to set an appropriate reference value and perform appropriate control.
In addition, at this time, in order to eliminate the case where there is some acquisition mistake or transient fluctuation of the power supply voltage value, when the state where the power supply voltage is larger than the predetermined voltage value continues for a predetermined time, The reference value was changed. Therefore, more appropriate control can be performed.

Further, in the above-described opening / closing member control apparatus, as described in claim 2, it is possible to suitably apply a plurality of types of values corresponding to the power supply voltage depending on the acquired power supply voltage value.
As a specific application configuration, as described in claim 3, the reference value switching unit acquires a plurality of temporary reference values set according to the acquired power supply voltage value, and the temporary reference value Detecting that the state where the power supply voltage value is larger than the predetermined voltage value has continued for a predetermined time by detecting that the state different from the reference value that has already been set continues for a predetermined time When the state where the power supply voltage value is larger than the predetermined voltage value continues for a predetermined time, it is preferable to change the reference value to a value indicated by the temporary reference value.
With this configuration, the reference value can be set more finely and more appropriate control can be performed.

  Further, as a specific usage configuration of the opening / closing member control device, the opening / closing member is a window glass provided on the door, and the determination unit determines whether the movement of the window glass is inhibited by the foreign matter. It is preferable that the determination is made.

According to the present invention, the reference value is switched according to the power supply voltage value by the reference value switching means. In other words, by setting a reference value according to the power supply voltage value, even in a high power supply voltage state, the time from the start of movement inhibition of the opening / closing member to the detection can be made equal to the normal time. It is possible to prevent the load applied to the foreign matter at the time of detection or the reverse load from becoming too high.
As described above, in the present invention, it is possible to set an appropriate reference value, and appropriate control can be performed.

It is a schematic diagram which shows the relationship between the motor rotation speed corresponding to a power supply voltage value, and a threshold value. It is a flowchart which shows the threshold value switching process of the opening-and-closing member control apparatus which concerns on the modification of this invention.

Hereinafter, an embodiment (this embodiment) of the present invention will be described. The embodiment described below is merely an example for facilitating the understanding of the present invention, and does not limit the present invention. That is, the present invention can be changed and improved without departing from the gist thereof, and the present invention includes its equivalents.
Moreover, although this example illustrated and demonstrated the foreign material pinching of the window glass 11 which is an opening / closing member, it is also applicable similarly regarding a foreign material entrainment.

The opening / closing member control device according to the present embodiment is a power window device 1 mounted on a vehicle S, and its mechanic configuration is shown in FIG. 1 and its electrical configuration is shown in FIG.
FIG. 1 is an explanatory diagram relating to the mechanic configuration of the power window device 1 according to the present embodiment.

The power window device 1 raises and lowers (opens and closes) a window glass 11 as an opening and closing member provided on the door 10 of the vehicle S by rotational driving of a motor 20. The power window device 1 has an elevating mechanism 2 as a driving mechanism for opening and closing the window glass 11.
The overall electrical configuration of the power window device 1 is as shown in FIG. 2, and includes a control unit 3 for controlling the operation of the elevating mechanism 2 and an operation switch for commanding the operation of the vehicle S occupant. 4 are provided as main components.

  The window glass 11 moves up and down between a fully closed position (top dead end) and a fully open position (bottom dead end) along a rail (not shown). The elevating mechanism 2 includes a motor 20 having a speed reduction mechanism fixed to the door 10, an elevating arm 21 having a fan-shaped gear 21 a driven by the motor 20, and a follower pivotally supported by the elevating arm 21. The main components are an arm 22, a fixed channel 23 fixed to the door 10, and a glass side channel 24 provided at the lower part of the window glass 11.

  The motor 20 is rotationally driven by electric power supplied from the control unit 3 and is rotatable in both forward and reverse rotational directions. When the motor 20 rotates, the lift arm 21 and the follower arm 22 swing in conjunction with the rotation of the motor 20, and the respective end portions thereof are regulated by the channels 23 and 24. That is, the elevating arm 21 and the driven arm 22 are driven as an X link, and as a result, the window glass 11 is moved up and down.

  Further, the motor 20 is integrally provided with a rotation detection device 25. The rotation detection device 25 is configured by a Hall element or the like, and outputs a pulse signal (speed detection signal or rotation speed signal) synchronized with the rotation of the motor 20 to the control unit 3. Such a pulse signal is output for each predetermined movement amount of the window glass 11 or for each predetermined rotation angle of the motor 20. That is, the rotation detection device 25 outputs a signal corresponding to the movement of the window glass 11 that is substantially proportional to the rotation speed of the motor 20.

Note that a relay 33 for protecting the motor 20 is provided in the drive circuit 32. The relay 33 is electrically connected to the motor 20, and the direction (direction) of the current flowing through the motor 20 is switched by switching the polarity of the relay 33. When the current flows in the forward direction, the motor 20 rotates in the forward direction, and when the current flows in the reverse direction, the motor 20 rotates in the reverse direction.
That is, when the motor 20 is driven to rotate in either direction, the motor 20 is driven with a predetermined duty ratio by the PWM signal output from the controller 31, and the voltage applied to the motor 20 is adjusted to control the speed of the motor 20. I do.

  The control unit 3 calculates the raising / lowering position of the window glass 11 based on said pulse signal. Further, the control unit 3 can calculate the rotational speed of the motor 20 or the ascending / descending speed of the window glass 11 corresponding to the interval of the pulse signals. More specifically, the control unit 3 (strictly speaking, a controller 31 to be described later) detects a rising edge or a falling edge of the pulse signal from the input pulse signal, that is, a pulse edge, and the interval between the pulse edges ( The rotation speed (rotation period) of the motor 20 is calculated based on the period and the pulse width, and the rotation direction of the motor 20 is detected based on the phase difference of each pulse signal.

  As described above, the control unit 3 indirectly calculates the movement speed of the window glass 11 based on the rotation speed (rotation cycle) of the motor 20 and determines the movement direction of the window glass 11 based on the rotation direction of the motor 20. I have identified. Further, the control unit 3 counts pulse edges. This pulse count value is added or subtracted with the opening / closing operation of the window glass 11. The control unit 3 specifies the opening / closing position of the window glass 11 based on the magnitude of the pulse count value.

  The control unit 3 will be described in more detail. The control unit 3 includes a controller 31 and a drive circuit 32. The controller 31 is configured by a microcomputer including a CPU, a memory (not shown) such as a ROM and a RAM, an input circuit, an output circuit, and the like. As shown in FIG. 2, the door opening / closing signal 6 is input to the controller 31. The door opening / closing signal 6 is a signal transmitted from a courtesy switch of the door 10 or the like. The controller 31 detects (determines) the open / closed state of the door 10 based on the door open / close signal 6. That is, the controller 31 functions as a detection unit that detects the open / closed state of the door 10.

  The controller 31 functions as a control unit together with the drive circuit 32 and opens and closes the window glass 11 according to an operation signal from the operation switch 4. More specifically, the operation switch 4 according to the present embodiment is configured by a swing type switch that can be operated in two steps, and has an open switch, a close switch, and an auto switch. When the occupant operates the operation switch 4, a command signal for opening and closing the window glass 11 is output to the controller 31. For example, when one end of the operation switch 4 is operated in one step, the opening switch is turned on, and a normal opening command signal for normally opening the window glass 11 (that is, opening movement only during operation) is sent to the controller 31. Is output. While receiving the normal opening command signal, the controller 31 rotates the motor 20 in the normal direction to cause the lifting mechanism 2 to perform the lowering operation in order to normally open the window glass 11.

  On the contrary, when the other end side of the operation switch 4 is operated in one step, the close switch is turned on, and a normal close command signal for normally closing the window glass 11 (that is, closing only during operation) is sent to the controller. 31 is output. While receiving the normal close command signal, the controller 31 causes the elevating mechanism 2 to perform the ascending operation by reversely rotating the motor 20 in order to normally close the window glass 11.

  When the operation switch 4 is operated in two steps toward one end, both the opening switch and the auto switch are turned on, and the window glass 11 is automatically opened (ie, moved until reaching the fully opened position even if the operation is stopped). An auto-open command signal is output to the controller 31. When receiving the auto-open command signal, the controller 31 rotates the motor 20 in the forward direction until the window glass 11 reaches the fully open position, and causes the elevating mechanism 2 to perform a continuous lowering operation (corresponding to the first operation).

  When the operation switch 4 is operated in two steps toward the other end, both the closing switch and the auto switch are turned on, and the window glass 11 is automatically closed (ie, moved until reaching the fully closed position even if the operation is stopped). ) Is output to the controller 31. When the controller 31 receives the auto-close command signal from the operation switch 4, the motor 20 is reversely rotated until the window glass 11 reaches the fully-closed position, and the lifting mechanism 2 is continuously raised.

  Further, the controller 31 functions as a “determination unit” in cooperation with the rotation detection device 25 described above, and based on the change in the operation state of the motor 20, the window glass 11 and its peripheral members (the window glass 11 in the door 10). It is a member located in the periphery, specifically, the presence or absence of a foreign object sandwiched between it and a window frame) is determined. More specifically, when receiving a pulse signal from the rotation detection device 25, the controller 31 determines the presence or absence of foreign matter between the window glass 11 and the window frame based on the pulse signal.

  Here, the presence / absence of a foreign object means the presence / absence of a foreign object between the upper end of the window glass 11 and the window frame when the window glass 11 is closed. When pinching occurs, the moving speed of the window glass 11 and the rotating speed of the motor 20 are reduced (the rotating cycle is lengthened). On the other hand, the controller 31 monitors the rotational speed of the motor 20 during the closing operation based on the pulse signal while the window glass 11 is closing. Then, the controller 31 detects the start of pinching when the rotation speed of the motor 20 during the closing operation starts to decrease, and thereafter the rotation speed reaches a preset threshold value (pinching determination threshold value). It is determined (confirmed) that pinching has occurred when the voltage drops.

And the controller 31 performs the process which reverses the operation | movement of the raising / lowering mechanism 2, when it determines with pinching having existed while the window glass 11 is moving open / close (that is, while the raising / lowering mechanism 2 is operating). . For example, when it is determined that the window glass 11 is caught while the window glass 11 is automatically closed, the controller 31 performs a process of reversing and lowering the continuous raising operation of the lifting mechanism 2.
That is, if the controller 31 determines that pinching has occurred, the controller 31 performs foreign object release processing. The foreign substance release process is a process for performing an operation different from the operation performed by the lifting mechanism 2 immediately before the determination. More specifically, when a continuous ascending operation that is a closing operation has been performed, in the subsequent foreign substance release processing, the elevating mechanism 2 is caused to perform a descending operation so that the window glass 11 is opened and moved by a predetermined amount. .

≪About threshold value switching process≫
Next, threshold value switching processing of the opening / closing member control device will be described.
This threshold value switching process is executed by the controller 31 provided in the control unit 3, and the controller 31 that performs the process serves as a “reference value switching unit”.
In this example, when the power supply voltage is higher than a predetermined value, the threshold value (corresponding to the “reference value”) is changed, and the process is executed in order to prevent the reverse load from becoming too high.
First, when the pinching determination threshold value switching process is executed, a power supply voltage is acquired in step S1, and it is determined whether or not the power supply voltage is equal to or higher than a specified voltage in step S2.

If it is determined in step S2 that the power supply voltage is not equal to or higher than the predetermined value (step S2: NO), the high voltage timer is initialized in step S7 (in this case, the high voltage timer = 0 is held as it is). In step S8, the threshold value is set to a normal value, and the process ends.
In other words, when the power supply voltage is less than the predetermined value, there is no problem that the power supply voltage is high, so the threshold is set to a normal value without using the high voltage timer. It is a thing.

  If it is determined in step S2 that the power supply voltage is equal to or higher than the predetermined value (step S2: YES), it is determined in step S3 whether or not the high voltage timer is on. Here, since the high voltage timer should not be on in the earliest determination, a negative determination is made in the earliest determination (step S3: N0), and the high voltage timer that measures the high voltage duration is turned on in step S4. Then, the process proceeds to step S5. As will be described later, when the power supply voltage is being monitored for a specified time (when it is not the earliest determination), the high voltage timer should already be on, so the determination is an affirmative determination, Step S4 will be skipped and it will progress to step S5.

Next, in step S5, it is determined whether or not the high voltage timer has passed a specified time.
If the high voltage timer has not passed the specified time (step S5: NO), the process returns to step S1, and once again acquires the power supply voltage to determine whether the power supply voltage is equal to or higher than the specified voltage. (Step S2). That is, it is determined once again whether the power supply voltage is equal to or higher than the specified voltage.
If the power supply voltage is not equal to or higher than the specified voltage (step S2: NO), the process proceeds to step S7, the high voltage timer is initialized (high voltage timer = 0), and the threshold value is set to a normal one in step S8. To finish the process.
In other words, if the high power supply voltage state does not continue for a predetermined time (if the power supply voltage returns below the specified value within the predetermined time), it is determined that the high voltage state is transient and normal operation is performed. Set the threshold.

In step S2, if the power supply voltage is equal to or higher than the specified voltage this time (step S2: YES), it is determined whether the high voltage timer is on in step S3. Since this is not the earliest determination, an affirmative determination is made, and it is again determined in step S5 whether or not the specified time has elapsed for the high voltage timer.
If the specified time has elapsed in the high voltage timer (step S5: YES), the threshold value is set for the high voltage in step S6, and the process is terminated.

That is, in this example, the voltage state from the time when the high voltage timer is turned on until the specified time is monitored. In other words, steps S1 to S5 are repeated until the specified time elapses to monitor whether the high voltage state is maintained or eliminated.
If the high voltage state is canceled before the specified time elapses, a negative determination is made in step S2 (step S2: NO), so the high voltage timer is cleared to 0 and a normal threshold value is set. Is done. On the other hand, if the high voltage state is maintained during the monitoring specified time, the threshold value is changed for the high power supply voltage value.
In this way, the power window device 1 according to the present embodiment can effectively prevent the reverse load from becoming high when pinching is detected by changing the threshold value according to the power supply voltage value.

With reference to FIG. 4, the level of the power supply voltage and the reversal load when pinching is detected will be described.
FIG. 4A is a schematic diagram showing the rotational speed of the motor 20 according to the power supply voltage when the conventional threshold value is not changed.
When the power supply voltage is high, the rotation speed of the motor 20 is faster than when the power supply voltage is low.
For this reason, when the threshold value is unchanged, the time from the start of pinching detection until the threshold value is reached (that is, the time until the motor rotation speed decreases to the threshold value due to pinching) is low power. The arrival time T2 at the high power supply voltage value is longer than the arrival time T1 at the voltage value (in this example, the arrival time at the normal power supply voltage).
Therefore, of course, the reversal load becomes larger when the power supply voltage is high.
However, as in this example shown in FIG. 4B, if two threshold values are prepared and can be changed depending on the power supply voltage value, the arrival time at the low power supply voltage value T1 = the arrival time at the high power supply voltage value. Since it can be set to T2, it can prevent that a reverse load becomes high.

≪Modification example≫
Next, a modified example of the threshold value switching process in the pinch determination according to the embodiment will be described with reference to FIG.
In the above embodiment, a power supply voltage value is first obtained, a temporary threshold value is set according to the power supply voltage, and a temporary reference value set according to the power supply voltage is used as necessary. It is configured to set as a value.
In other words, in the above embodiment, only two threshold values, the threshold value at the time of high power supply voltage and the normal threshold value, are prepared as threshold values. A plurality of types of threshold values are prepared in accordance with the supplied power supply voltage.
Hereinafter, the flow of control will be described with reference to the flowchart of FIG.

First, when the pinching determination threshold value switching process is executed, a power supply voltage is acquired in step S11, and a temporary threshold value is determined in step S12.
In this example, a threshold distribution table T in which a plurality of threshold values are assigned to a plurality of power supply voltage values that are grouped is set, and threshold values are set according to the power supply voltage values acquired in step S11. Is selected and set as a provisional threshold value.
The threshold distribution table in FIG. 5 is a conceptual diagram of the table. For example, if the power supply voltage value is in the range of a (V) or more and less than b (V), “threshold 2” is set. If the predetermined condition is satisfied in the subsequent processing, the threshold value (hereinafter simply referred to as “threshold value”) that uses “threshold value 2” selected as the temporary threshold value in step S12 is selected. ).
In this example, the power supply voltage minimum value (a (V)) set in the threshold distribution table T is a normally set power supply voltage value, and the power supply voltage is a (V). When the value exceeds the threshold, the threshold is set according to the degree of the excess.
That is, in the above-described embodiment, one threshold value is set when the normal power supply voltage value is exceeded, but in this example, a plurality of threshold values when the normal power supply voltage is exceeded are prepared. Will be.

Next, in step S13, it is determined whether or not the temporary threshold value selected in step S12 is the same as the currently set threshold value.
If it is determined in step S13 that the temporary threshold value is the same as the currently set threshold value (step S13: YES), a voltage timer is initialized in step S19 (in this case, voltage timer = 0). In step S18, the set threshold value is fixed as it is (without changing the threshold value), and the process is terminated.
In other words, if the provisional threshold and the installed threshold are the same, there is no problem that the power supply voltage has changed, so the threshold is kept as it is without a voltage timer. That's what it meant.

  If it is determined in step S13 that the temporary threshold is not the same as the currently set threshold (step S13: NO), it is determined in step S14 whether or not the voltage timer is on. To do. Here, since the voltage timer should not be turned on in the earliest determination, a negative determination is made in the earliest determination (step S14: NO), and in step S15, the same voltage duration (that is, the same temporary threshold duration is continued). The voltage timer for measuring (time) is turned on, and the process proceeds to step S16. As will be described later, when the specified time is being monitored (when it is not the earliest determination), the voltage timer should already be on, so the determination is affirmative and step S15 is skipped. Then, the process proceeds to step S16.

Next, in step S16, it is determined whether or not the voltage timer has passed a specified time.
If the specified time has not elapsed (step S16: NO), the process returns to step S11, the power supply voltage is acquired once again, a temporary threshold is set (step S12), and step S13. Then, it is determined whether or not the temporary threshold value is the same as the currently set threshold value. That is, once again, it is determined whether or not the temporary threshold value selected according to the power supply voltage value matches the threshold value.
If it is determined in step S13 that the temporary threshold value is the same as the currently set threshold value (step S13: YES), the voltage timer is initialized in step S19 (in this case, the voltage timer = In step S18, the set threshold value is fixed as it is (without changing the threshold value), and the process is terminated.
In other words, if the state where the threshold value must be changed (the state where the power supply voltage changes more than allowable) does not continue for the predetermined time (if the power supply voltage returns to the allowable range within the predetermined time), the power supply voltage A normal threshold value is set by determining that the state in which the change has exceeded the allowable value is transient.

In step S13, if it is determined again that the temporary threshold value is not the same as the currently set threshold value (step S13: NO), it is determined whether the voltage timer is on in step S14. However, as described above, since the monitoring is being performed this time and not the earliest determination, the voltage timer is on and the determination is affirmative. Then, step S15 is skipped, and it is determined again whether or not the voltage timer has passed the specified time in step S16.
Next, if the specified time has elapsed in the voltage timer (step S16: YES), in step S17, the temporary threshold value is rewritten as the threshold value, and the rewritten threshold value is determined in step S18. finish.

That is, in this example, the voltage state from the time when the voltage timer is turned on until the specified time is monitored. In other words, steps S11 to S16 are repeated until the specified time elapses, and the state is monitored.
If the provisional threshold value matches the preset threshold value before the specified time elapses (if the change state exceeding the allowable power supply voltage is released), an affirmative determination is made in step S13 ( Step S13: YES), the preset threshold value is fixed. On the other hand, if the temporary threshold value is different from the preset threshold value during the specified monitoring period (if the change state exceeding the allowable power supply voltage continues), the threshold value is Can be rewritten.
In this way, the power window device 1 according to the present embodiment is changed to an appropriate threshold value according to the acquired power supply voltage value, and it is effective and finely determined that the inversion load becomes high when pinching is detected. Can be prevented.
It should be noted that both the above embodiment and the modified examples can be used in combination with conventional voltage correction, and by configuring in this way, it becomes possible to realize finer control.
