Description

[0001]
[Industrial application fields]
The present invention relates to a window opening / closing control device suitable for controlling opening / closing of a vehicle window and other various windows.
[0002]
[Prior art]
Conventionally, for example, an automobile window opening / closing control device is disclosed in Japanese Patent Application Laid-Open No. 8-240068.
In this window opening and closing control device, the light emitted from the light emitting element fixed to the center pillar between all the seats and the rear seats of the automobile enters a foreign object between the window and the window frame during the window closing operation. When the reflected light is reflected, the window is stopped or reversed by determining whether the foreign object is caught by comparing the received light amount of the light receiving element that receives the reflected light with a threshold value.
[0003]
[Problems to be solved by the invention]
By the way, in the window opening / closing control apparatus, the amount of change in reflected light due to foreign matter with respect to the light from the light emitting element is larger than the amount of disturbance light such as sunlight, reflected light due to window dirt, or reflected light from the side mirror of an automobile. Few. For this reason, it is difficult to determine pinching unless the threshold is set to a sensitive value.
[0004]
However, if the threshold value is set to a sensitive value in this way, there is a problem that it is erroneously determined that foreign matter is caught even by the disturbance light.
On the other hand, the inventor examined in detail the light incident on the light receiving element.
According to this, disturbance light such as sunlight, reflected light due to window dirt and reflected light from the side mirror of an automobile tends to travel from the outside of the passenger compartment toward the inside of the passenger compartment, whereas the window from the passenger compartment side. It was found that the light of the light emitting element reflected by the foreign matter sandwiched by the light tends to travel from the vehicle interior side toward the outside of the vehicle interior.
[0005]
Therefore, the present invention pays attention to such matters, and devised the number and arrangement of the light emitting elements so that the disturbance light and the reflected light from the foreign object can be distinguished, and the foreign object pinching determination by the window is determined. It is an object of the present invention to provide a window opening / closing control device that can be accurately performed without being affected.
[0006]
[Means for Solving the Problems]
In solving the above-mentioned problems, according to the first and third aspects of the present invention, the optical sensor emits light so as to cross the direction in which foreign matter enters the opening between the window frame and the window frame. And at least first and second light receiving elements that sequentially receive light from the light emitting element reflected by the foreign object as reflected light according to the movement of the foreign object in the intrusion direction.
[0007]
When the light receiving order determining means determines that the light receiving order of the second light receiving elements is after the first light receiving elements, the foreign object intrusion direction determining means determines that the foreign objects enter the opening from the interior of the vehicle. Then, the control means controls the operating state of the driving means so as to stop the closing operation of the window based on the determination by the foreign substance intrusion direction determination means.
As described above, when the foreign object intrusion direction determining means determines that the foreign object enters the opening from the passenger compartment under the action of the optical sensor, the control means is configured to stop the window closing operation. Control the operating state.
[0008]
Thereby, it is possible to prevent foreign matter from being caught by the window. In this case, in order to prevent the foreign object from being caught, the first and second light receiving elements receive the reflected light in the order in which they do not depend on the comparison determination between the fluctuation value of the load on the window and the threshold value for the pinching determination. It is made.
Therefore, even if the amount of reflected light from the foreign material is smaller than the amount of ambient light such as reflected light due to sunlight or window dirt, it is not erroneously determined that the foreign material is caught due to the influence of the ambient light.
[0009]
According to the second and third aspects of the invention, the optical sensor includes: a light emitting element that emits light so as to intersect a direction in which foreign matter enters the opening between the window frame and the foreign object; At least first and second light receiving elements that sequentially receive light according to the movement of the foreign matter in the intrusion direction as light reflected from the light emitting element.
[0010]
Further, during the window closing operation, the foreign matter intrusion direction determining means determines that the foreign matter enters the opening from the vehicle interior when the light receiving order determining means determines that the light receiving order of the second light receiving element is after the first light receiving element. It is determined that the foreign matter enters the opening from the outside of the passenger compartment when it is determined that the first light receiving element is after the second light receiving element.
[0011]
When the foreign object intrusion direction determining means determines that a foreign object has entered the opening from the passenger compartment, the pinch determination means uses the fluctuation value of the detected operation state of the operating state detection means as a threshold value for determining the foreign object pinching. Instead, foreign object pinching determination is performed by comparing with a value more sensitive than the threshold value. In addition, when the foreign object intrusion direction determining means determines that the foreign object has entered the opening from the outside of the passenger compartment, the pinching determination means is less sensitive to the detected operating state variation value than the threshold value instead of the threshold value. The foreign object pinching determination is performed by comparing with a correct value.
[0012]
The control means controls the operating state of the driving means during the closing operation of the window based on the determination result of the pinching determination means.
Thereby, it is possible to prevent foreign matter from being caught by the window. In this case, in order to prevent the foreign matter from being caught, the first and second light receiving elements are arranged in the order in which the reflected light is received.
[0013]
Moreover, as described above, the foreign object pinching determination by the pinching determination unit is performed in combination with the intrusion direction determination by the foreign object intrusion direction determination unit. Therefore, it is possible to perform the foreign object pinching determination by the window with higher accuracy.
In this case, as described above, when the foreign matter intrusion direction determining means determines that foreign matter has entered the opening from the vehicle interior, the threshold value for comparing the variation value of the detected operating state of the operating state detecting means is determined from this threshold value. Since a sensitive value is also used, it is possible to perform the pinching determination due to the entry of foreign matter from the vehicle compartment into the opening. On the other hand, as described above, when the foreign matter intrusion direction determining means determines that a foreign object has entered the opening from the outside of the passenger compartment, the threshold value for comparing the variation value of the detected operating state of the operating state detecting means is greater than this threshold value. Since the insensitive value is used, it is not erroneously determined that the foreign object is caught from outside the passenger compartment.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows an example in which the present invention is applied to an automobile window opening / closing control device.
In FIG. 2, the code | symbol 10 has shown the door of the said motor vehicle, The window 12 is attached to the window frame 11 of this door 10 so that opening and closing is possible. Here, the window 12 closes as it rises, while it opens as it descends.
[0015]
The window opening / closing control device includes a drive mechanism 20 provided in the lower part of the door 10, and this drive mechanism 20 is connected between the DC motor M and the lower edge of the window 12 and the DC motor M. And a coupling mechanism (not shown).
Then, the drive mechanism 20 raises or lowers the window 12 via the connection mechanism as the DC motor M rotates forward or backward. In FIG. 2, reference numeral 13 denotes a weather strip.
[0016]
Further, as shown in FIG. 1, the window opening / closing control device includes a closing operation switch 30 and an opening operation switch 40, a rotation sensor 50, an optical sensor 60, a light emission driving circuit 70a connected to the optical sensor 60, and a signal. A processing circuit 70b, a microcomputer 80 connected to the closing operation switch 30, the opening operation switch 40, the rotation sensor 50, the light emission driving circuit 70a and the signal processing circuit 70b, and a motor driving circuit 90 connected to the microcomputer 80 are provided. ing.
[0017]
The closing operation switch 30 generates a closing operation signal for closing the window 12 by the ON operation. On the other hand, the opening operation switch 40 generates an opening operation signal for opening the window 12 by the ON operation.
The rotation sensor 50 is composed of, for example, a Hall element, and the rotation sensor 50 is disposed in the lower portion of the door 10. The rotation sensor 50 detects the rotation of the DC motor M and generates a pulse signal.
[0018]
As shown in FIGS. 1 and 2, the optical sensor 60 is attached to the center pillar 14 on the door 10 side between the front seat and the rear seat in the interior of the vehicle in the vicinity of the rear edge of the window frame 11. It has been.
As shown in FIG. 2, the optical sensor 60 includes a substrate 61, and the substrate 61 extends from the inner wall of the center pillar 14 toward the vehicle interior at a right angle thereto. The substrate 61 is located in a horizontal plane, and a light emitting element 62 and a pair of light receiving elements 63 and 64 are mounted on the upper surface of the substrate 61.
[0019]
The light emitting element 62 includes an infrared light emitting diode. The light emitting element 62 directs light from the infrared light emitting diode toward the front edge side from the rear edge side of the window frame 11 of the door 10. 1 and 2 is mounted on the substrate 61 so as to be intermittently emitted in the form of a radiation beam in the direction indicated by the dashed arrow in FIGS.
The pair of light receiving elements 63 and 64 are mounted on the upper surface of the substrate 61 on both sides of the light emitting element 62, and the light receiving element 63 is located farther from the inner wall of the center pillar 14 than the light receiving element 64. Yes.
[0020]
Here, the pair of light receiving elements 63 and 64 receive light from the light emitting element 62 reflected by the foreign matter A in the vehicle interior (see FIG. 2) at the light receiving surfaces 63a and 64a. The light receiving axes of these light receiving elements 63 and 64 are positioned so as to spread from the bottom to the top in FIG.
Each of the light receiving elements 63 and 64 has a built-in phototransistor, and each of the light receiving elements 63 and 64 detects the light received by the light receiving surface as the amount of light received by each phototransistor.
[0021]
The light emission drive circuit 70a is controlled by the microcomputer 80 to drive the light emitting element 62 to emit light. The signal processing circuit 70b performs signal processing on the amount of light received from each of the light receiving elements 63 and 64, and generates each as a signal processing signal. The level of each signal processing signal corresponds to the amount of light received from each light receiving element 63, 64.
The microcomputer 80 is powered by the battery B and enters an operating state. The microcomputer 80 executes a computer program according to the flowcharts shown in FIGS. 3 and 4. During this execution, the microcomputer 80 calculates the rotational speed of the DC motor M and opens / closes the window 12. Arithmetic processing for control processing, foreign object intrusion determination processing, and the like is performed.
[0022]
The motor drive circuit 90 drives the DC motor M of the drive mechanism 20 so as to rotate forward or reversely under the control of the microcomputer 80.
Hereinafter, the operation of the present embodiment configured as described above will be described.
When the window opening / closing control apparatus according to the present invention is mounted on a vehicle, the microcomputer 80 is connected to the positive terminal of the battery B as shown in FIG. It is assumed that the window 12 is in the fully open position at the present stage.
[0023]
When the microcomputer 80 is supplied with power from the battery B by the connection as described above, the microcomputer 80 starts executing the computer program according to the flowcharts of FIGS. 3 and 4 and performs initialization processing in step 100.
Then, in step 110, intermittent light emission processing of the light emitting element 62 is performed. Accordingly, the light emission drive circuit 70 a is controlled by the microcomputer 80 to drive the infrared light emitting diode of the light emitting element 62 to emit light intermittently. Therefore, the light emitting element 62 intermittently emits the light of the infrared light emitting diode in the form of a radiation beam in the direction indicated by the dashed arrow in FIGS.
[0024]
When at least one of the light receiving elements 63 and 64 receives light accompanying this emission, the signal processing circuit 70b performs signal processing on the amount of received light to generate a signal processing signal.
In such a state, if there is no output from either the closing operation switch 30 or the opening operation switch 40, the determination of NO in each of steps 120 and 130 and the stopping process of the DC motor M in step 131 are repeated.
[0025]
Next, when the closing operation signal is generated from the closing operation switch 30 when the opening operation switch 40 is turned off, it is determined in step 130 that NO is determined in step 120 based on the determination that the window 12 is requested to be lifted. It is determined as YES. Along with this determination, in step 132, an ascending command for raising the window 12 is output.
[0026]
For this reason, the motor drive circuit 90 drives the DC motor M of the drive mechanism 20 in the normal direction based on the ascent command of the microcomputer 80, and the window 12 starts the closing operation due to the ascent. At this time, the rotation sensor 50 detects the rotation of the DC motor M and starts outputting pulse signals sequentially.
Next, when the signal processing signal from the signal processing circuit 70b is input to the microcomputer 80 in step 133, whether or not both received light amounts of both the light receiving elements 63 and 64 are changed in the next step 140. Judgment is made. Specifically, this determination is made based on whether or not both the light receiving amounts of both the light receiving elements 63 and 64 exceed a predetermined threshold value TH (see FIG. 5).
[0027]
If there is no change in the amount of light received by both the light receiving elements 63 and 64, it is determined NO in step 140 because there is no foreign matter. Next, at step 141, the rotational speed N of the DC motor M is calculated by a period determined by the current pulse signal from the rotation sensor 50 and the previous pulse signal.
At this stage, since the window 12 has just started to rise from the fully open state, NO is determined in step 150.
[0028]
Thereafter, the process through steps 120 to 150 is repeated. When the rotational speed of the DC motor M becomes equal to or lower than a predetermined rotational speed (corresponding to a value that causes the DC motor M to be locked when the window 12 is fully closed), the determination in step 150 is YES. Stop processing is performed. As a result, the DC motor M is stopped by the motor drive circuit 90.
[0029]
Further, when both the light receiving amounts of both the light receiving elements 63 and 64 change while the window 12 is rising as described above, when the computer program reaches step 140, the determination in step 140 is YES. Become.
Next, in step 160, it is determined which of the light receiving amounts of both the light receiving elements 63 and 64 has changed first.
[0030]
For example, when the foreign matter A in the vehicle interior moves in the direction of the two-dot chain line arrow and enters the opening between the window frame 11 and the window 12 as shown in FIG. The light from the light emitting element 62 reflected by the foreign matter A first enters the light receiving element 63 and then enters the light receiving element 64 because it is further on the vehicle interior side.
[0031]
Therefore, as shown in FIG. 5A, the amount of light received by the light receiving element 63 increases ahead of the amount of light received by the light receiving element 64 and exceeds the threshold value TH. According to FIG. 5A, after the amount of light received by the light receiving element 63 exceeds the threshold TH at time t1, the amount of light received by the light receiving element 64 exceeds the threshold TH at time t2.
Therefore, the determination in step 160 is YES, and in step 161, it is determined that the foreign object A has entered the opening between the window frame 11 and the window 12 from the vehicle interior. This means that the foreign object A is caught by the window 12 from the vehicle interior side.
[0032]
Accordingly, in step 162, the DC motor M is reversely rotated. As a result, the DC motor M reverses and the window 12 descends.
Thereafter, when the number of pulse signals from the rotation sensor 50 is counted by a predetermined number of pulses (corresponding to the descending distance of the window 12), the determination in step 170 is YES, and in step 171, the window under the DC motor M stop processing is performed. The descent of 12 stops.
[0033]
On the other hand, when a foreign object enters from the outside of the passenger compartment through the openings of the window frame 11 and the window 12, the light from the light emitting element 62 reflected by the foreign object is first received by the light receiving element 64. Is incident on the light receiving element 63.
For this reason, as shown in FIG. 5B, the amount of light received by the light receiving element 64 increases ahead of the amount of light received by the light receiving element 63 and exceeds the threshold value TH. According to FIG. 5B, after the amount of light received by the light receiving element 64 exceeds the threshold TH at time T1, the amount of light received by the light receiving element 64 exceeds the threshold TH at time T2.
[0034]
Therefore, the determination in step 160 is NO, and in step 163, it is determined that the foreign matter has entered the vehicle interior in a direction from the outside of the vehicle interior to the vehicle interior.
By this determination, the foreign substance intrusion determination process (the processes of steps 160 to 162) in the opening of the window 12 with the window frame 11 is masked, and the window 12 continues to rise without being stopped or lowered. Therefore, even if a foreign object tries to enter from the outside of the passenger compartment, the window 12 is closed regardless of the foreign object. For this reason, the harm to the vehicle interior by the said foreign material can be prevented beforehand.
[0035]
Further, the determination of YES or NO in step 160 is made in the order in which both light receiving elements 63 and 64 receive light from the light emitting element 62 reflected by the foreign matter. Therefore, even if the amount of reflected light from the foreign object is smaller than the amount of ambient light, the light receiving element does not enter the interior of the vehicle, but the light receiving element reflects the ambient light (for example, reflection due to sunlight or dirt on the window 12). Light), it is not erroneously determined that a foreign object is caught.
[0036]
Further, as described above, the light receiving axes of the light receiving elements 63 and 64 are located in a divergent shape from the lower side to the upper side in FIG. 2, so that the interval between the light receiving axes of these light receiving elements 63 and 64 is as narrow as possible. By doing so, it is possible to accurately perform the determination of YES or NO in step 160 while forming the optical sensor 60 compactly.
[0037]
If the determination in step 120 is YES based on the generation of the opening operation signal from the opening operation switch 40, the window 12 is lowered in step 121 based on the determination that the window 12 has a lowering request. The lowering process is performed.
For this reason, the motor drive circuit 80 drives the DC motor M, and the window 12 descends. After the processing in step 121, in step 122, the rotation speed N of the DC motor M is calculated based on the pulse signal from the rotation sensor 50.
[0038]
If the rotational speed N is equal to or lower than the predetermined value, a determination of YES is made in step 180, and the DC motor M is stopped in step 181.
FIG. 6 shows a main part of a modification of the above embodiment.
In this modification, the flowchart shown in FIG. 6 is employed instead of the flowchart of FIG. 4 described in the above embodiment. Other configurations are the same as those in the above embodiment.
[0039]
In this modified example configured as described above, when it is determined in step 161 that the foreign object A has entered the opening of the window 12 with the window frame 11 from the vehicle interior side as in the above embodiment, the next step. In 161a, the rotation speed is calculated based on the pulse signal from the rotation sensor 50.
Then, in step 161b, the rotational speed variation rate R is calculated from the current rotational speed and the previous rotational speed, and in step 161c, the variation rate R is compared with a predetermined variation rate Rin. Here, the predetermined fluctuation rate Rin is for determining whether the foreign object A is caught by the window 12, and is set to a value that is more sensitive than the conventional value.
[0040]
If the fluctuation rate R is equal to or higher than the fluctuation rate Rin at the present stage, it means that the foreign object A on the vehicle interior side is caught by the window 12, so that a determination of YES is made in step 161c. Along with this, the processing after step 162 is performed in the same manner as in the above embodiment to prevent the foreign matter A from being caught.
In this case, as described above, the determination of the trapping of the foreign matter A from the vehicle interior side is performed by combining the determination of the light receiving order in step 160 and the comparison determination of the variation rate R of the variation rate R in step 161c. The accuracy of the pinching determination can be further improved.
[0041]
Further, in the determination in step 161c, the variation rate Rin is a value that is not related to the amount of received light unlike the threshold value TH described in the above embodiment. Therefore, the variation rate Rin is a value that is more sensitive than the conventional value. Even in such a case, the pinching determination can be performed with high accuracy without being affected by the disturbance light.
As described in the above embodiment, when it is determined in step 163 that a foreign object has entered from outside the vehicle compartment, the rotation speed is calculated based on the pulse signal from the rotation sensor 50 in the next step 163a. The
[0042]
Then, in step 163b, the rotational speed variation rate R is calculated from the current rotational speed and the previous rotational speed, and in step 163c, the variation rate R is compared with a predetermined variation rate Rout. Here, the predetermined fluctuation rate Rout is used to determine whether the foreign object is caught by the window 12, and is set to a value that is insensitive to the conventional value.
[0043]
If the variation rate R is equal to or greater than the variation rate Rout at the present stage, it means that the foreign object from outside the passenger compartment is caught by the window 12, and therefore, determination of YES is made in step 163c. Along with this, the processing after step 162 is performed in the same manner as in the above embodiment to prevent foreign matter from being caught from the outside of the passenger compartment.
In this case, as described above, the foreign object pinching determination from the outside of the passenger compartment is performed by combining the determination of the light receiving order in step 160 and the comparison determination of the variation rate R of the variation rate R in step 163c. The jamming determination can be performed without being affected by the disturbance light.
[0044]
In the above embodiment, the example in which the pair of light receiving elements 63 and 64 is provided on the substrate 61 in the optical sensor 60 has been described. Instead, three or more light receiving elements are provided on the substrate 61. You may implement. In this case, if the number of light receiving elements is an even number, the same number of light receiving elements may be arranged on both sides of the light emitting element 62. If the number of light receiving elements is three, two light receiving elements are used instead of the light receiving elements 63 or 64. What is necessary is just to arrange.
[0045]
In the above-described embodiment, the example in which the light emitting element 62 and the two light receiving elements 63 and 64 of the optical sensor 60 are horizontally arranged has been described. Instead, one of the two light receiving elements 63 and 64 is replaced with the light emitting element 62. The other light receiving element may be disposed below the light emitting element 62, and both the light receiving elements 63 and 64 may be disposed above or below the light emitting element 62. It may be.
[0046]
As a result, as in the above-described embodiment, it is possible to distinguish and detect the intrusion of the foreign matter going from the inside to the outside of the passenger compartment and the foreign matter going in the opposite direction into the opening between the window frame 11 and the window 12.
Here, the light receiving elements 63 and 64 may be arranged so as to be positioned above and below the light emitting element 62, or may be arranged directly above or below the light emitting element 62. In this case, it is desirable that the angle formed by the optical axes of the light receiving elements 63 and 64 is larger than that described in the above embodiment.
[0047]
In the above embodiment, the light receiving axis of each of the light receiving elements 63 and 64 is located in a divergent shape from the lower side to the upper side in FIG. The 64 light receiving axes may be parallel to each other.
Moreover, although the said embodiment demonstrated the example which employ | adopted the infrared light emitting diode as the light emitting element 62 of the optical sensor 60, not only this but another light emitting diode, a laser diode, etc. are employ | adopted as the light emitting element 62. You may implement.
[0048]
In implementing the present invention, the optical sensor 60 is not limited to the center pillar 14 and may be attached to a part of the inner wall of the door 10 in the vicinity of the rear mirror on the door 10 side, for example.
In implementing the present invention, instead of the determination based on the threshold value TH in step 140, the signal processing circuit 70b compares the received light amount from each of the light receiving elements 63 and 64 with the threshold value TH so that each received light amount is a threshold value. The determination in step 140 may be performed by generating signal processing signals when TH is exceeded and inputting these signal processing signals to the microcomputer 80.
[0049]
Further, in the above embodiment, an example is described in which the entry of foreign matter from the outside of the passenger compartment into the opening between the window 12 and the window frame 11 is masked by the processing in steps 140, 160, and 163. However, instead of this, the threshold TH in Step 140 may be increased to make the determination sensitivity insensitive, thereby preventing erroneous determination caused by the disturbance light.
[0050]
In implementing the present invention, instead of the fluctuation rate of the rotational speed described in the above modification, the fluctuation rate of the cycle corresponding to the rotation speed, or the fluctuation value of the operating state of the coupling mechanism of the drive mechanism 20 or the like. Or the like may be adopted as a determination criterion in steps 161c and 163c. In this case, in place of the rotation speed in each step 161a, 163a and the fluctuation rate in steps 161b, 163b, the cycle, the fluctuation rate, the operating state, or the fluctuation value thereof are calculated.
[0051]
In implementing the present invention, the present invention may be applied to doors of various seats such as passenger seats and driver's seats, sunroofs, various vehicles, ships, and window opening / closing control devices for general buildings. In this case, the opening / closing direction of the window is not limited to the up / down direction, and may be opened / closed in an arbitrary direction such as a horizontal direction.
In implementing the present invention, not only the rotation of the DC motor M but also, for example, the output of a sensor that detects the operating state of the drive mechanism 20 is input to the microcomputer 80 instead of the output of the rotation sensor 50. May be implemented. The rotation sensor 50 is not limited to the Hall element, and any sensor may be used as long as the rotation of the DC motor M can be detected.
[0052]
In implementing the present invention, each step in the flowchart of the above embodiment may be realized as a function execution unit by a hardware logic configuration.

A light receiving order determining means (160) for determining a light receiving order of the reflected light of the first and second light receiving elements during the closing operation of the window;
When the light receiving order determining means determines that the light receiving order of the second light receiving element is after the first light receiving element, it determines that the foreign matter enters the opening from the interior of the vehicle, and the first light receiving Foreign matter intrusion direction determining means (161) for determining that the foreign matter enters the opening from the outside of the passenger compartment when it is determined that the light receiving order of the elements is after the second light receiving element;
When the foreign object intrusion direction determining means determines that the foreign object has entered the opening from the vehicle interior, the pinching determination means is more sensitive than the threshold value for the variation value of the detection operation state instead of the threshold value. The foreign object intrusion direction determining means determines that the foreign object has entered the opening from the outside of the passenger compartment when the foreign object intrusion direction determining unit determines that the foreign object has entered the opening. A window opening / closing control device that performs the foreign object pinching determination by comparing with a value that is insensitive to the threshold value instead of the threshold value. The light emitting element and the first and second light receiving elements are arranged vertically in the vicinity of the inside of the window,
The light receiving direction with respect to the reflected light of the first light receiving element is directed more inward of the window than the light receiving direction with respect to the reflected light of the second light receiving element. Window opening / closing control device.
