Description

  The present invention relates to a vehicle window glass elevating device and a vehicle.

  2. Description of the Related Art In recent years, vehicles have been equipped with a vehicle window glass lifting device that automatically lifts and lowers the window glass in order to facilitate opening and closing the window glass.

  The vehicle window glass elevating device includes a drive mechanism that is arranged on a door of a vehicle and moves the window glass in the vertical direction, and a control unit that controls the drive mechanism.

  In a vehicle window glass elevating device, a mechanism for preventing the window glass from being caught is generally provided in order to elevate and lower the window glass electrically.

  As such a mechanism, the change in the rotation speed of the motor driving the window glass is monitored, and when the load increases while the window glass is rising and the rotation speed of the motor decreases, the foreign object is caught by the window glass. It is determined that, and various safety operations such as reversing the moving direction of the window glass and automatically lowering the window glass are performed.

  However, in such a mechanism, since a safe operation is performed after a foreign object (a part of the human body or the like) is actually sandwiched, there is a problem with safety from the viewpoint that a load is applied to the human body. . For example, in such a mechanism, an area of, for example, 4 mm from the window glass cut-off edge is often a dead zone so that the window glass cut-off is not erroneously detected as being pinched. For example, when an infant's finger is pinched, In some cases, there was a risk that safe operation would not be performed, and an improvement was desired.

  There exists patent document 1 as a window glass raising / lowering device for vehicles which solved such a problem.

  In Patent Document 1, a camera is installed on the vehicle interior side with respect to the window glass and below the front side of the vehicle with respect to the window glass, and there is a risk of being pinched by the window glass based on an image captured by the camera. It describes that foreign objects are detected and various safety operations such as automatically lowering the window glass are performed.

  Moreover, in patent document 1, when the marker applied to the periphery of a window frame, the edge of the outline of a window frame, etc. is used as a feature quantity for a foreign substance determination, and a foreign substance intervenes between the marker etc. used as a feature quantity and a camera It describes that various safety operations are performed.

  As in Patent Document 1, by detecting a foreign object that may be caught in the window glass from an image captured by a camera, it is possible to perform a safe operation before the occurrence of the pinching, and the safety is further improved. improves.

  The frame portion 22 includes a rear standing portion 22a extending upward from the rear end portion of the storage portion 21 in the front-rear direction of the vehicle, and a front standing portion extending upward from the storage portion 21 on the front side of the rear standing portion 22a. 22b and an upward extending portion 22c extending from the upper end portion of the rear standing portion 22a to the upper end portion of the front standing portion 22b. When the window glass 3 is fully closed, the window glass 3 is disposed in a space surrounded by the frame portion 22 and the upper end portion of the door trim 23. That is, the frame portion 22 and the upper end portion of the door trim 23 constitute the window frame 25. In the present embodiment, the window frame 25 refers to a portion in contact with the outer edge of the window glass 3 in a state where the door 2 and the window glass 3 are closed.

  The vehicle window glass elevating apparatus 1 includes a drive mechanism 4 that drives the window glass 3 and a control unit 5 that controls the drive mechanism 4.

  The drive mechanism 4 moves the window glass 3 in the vertical direction with respect to the window frame 25, and converts the motor 41 such as a DC motor and the driving force of the motor 41 into the vertical movement force of the window glass 3. A power conversion mechanism 42. The power conversion mechanism 42 includes, for example, a carrier plate that supports the window glass 3 and slides along the guide rail, and is attached to the wire by sliding the wire along the guide rail by the driving force of the motor 41. A window regulator or the like that moves the carrier plate and the window glass 3 in the vertical direction along the guide rail can be used. Further, as the power conversion mechanism 42, an X-arm type regulator or another type can be used.

  The door 2 is provided with a switch (SW) 24 for raising and lowering the window glass 3. An output signal line of the switch 24 is connected to the control unit 5. The switch 24 is composed of, for example, a two-stage click type swing switch. When one end of the descending side is clicked by one stage, the descending first stage click signal is clicked, and one end of the descending side is clicked by two stages. When the second side click signal of the descending side is clicked, the first side click signal of the rising side when the other end side that is the rising side is clicked by one step, and when the other end side that is the rising side is clicked by two steps The side second stage click signal is configured to be output to the control unit 5.

  The control unit 5 controls the drive mechanism 4 in accordance with a signal from the switch 24 and moves the window glass 3 in the vertical direction. The control unit 5 is mounted on the door 2 as a control unit in which a CPU, a memory, an interface, software, and the like are appropriately combined. The control unit 5 may be mounted as a function in an electronic control unit (ECU) that controls, for example, a vehicle mirror or a seat other than the door 2.

  When the descending first step click signal is input from the switch 24, the control unit 5 descends the window glass 3 while the signal is input, and when the descending second step click signal is input. Is configured to control the drive mechanism 4 so that the window glass 3 is automatically lowered until the window glass 3 is lowered to the lowest position or the switch 24 is operated again. Further, when the ascending side first stage click signal is input from the switch 24, the control unit 5 ascends the window glass 3 while the signal is input, and the ascending side second stage click signal is input. In this case, the drive mechanism 4 is controlled so that the window glass 3 is automatically raised until the window glass 3 is raised to the top or the switch 24 is operated again.

  Hereinafter, a configuration for preventing pinching by the window glass 3 will be described.

  The vehicle window glass elevating device 1 images a detection line 6 provided on the vehicle interior side of the window glass 3 along at least a part of the outer edge of the window glass 3 in a state where the door 2 and the window glass 3 are closed. A camera 7 is provided. In the present embodiment, based on the image captured by the camera 7, it is determined whether there is a foreign object that may be caught by the window glass 3. The specific configuration and mounting position of the camera 7 will be described later.

  The detection line 6 serves as a reference for determining whether there is a foreign object that may be caught by the window glass 3, and is set closer to the vehicle interior than the window glass 3. The specific configuration and setting position of the detection line 6 will be described later.

  In the present embodiment, a light source 8 that irradiates infrared light toward the detection line 6 is further provided. The camera 7 is composed of an infrared camera that captures infrared light that is irradiated from the light source 8 and reflected by the detection line 6. By providing the light source 8, it is possible to detect a foreign object that may be caught even at night and in a dark place where infrared rays other than night reach, such as an underground parking lot. As the light source 8, what irradiates near infrared light can be used.

  The control unit 5 includes a detection unit 51 that detects a shielding state in which at least a part of the detection line 6 captured by the camera 7 is shielded by a foreign substance, and a shielding state that is detected by the detection unit 51 when the window glass 3 is moved by the drive mechanism 4. And a pinching prevention unit 52 that causes the drive mechanism 4 to perform a pinching prevention operation for preventing pinching by the window glass 3. The detection unit 51 is an aspect of the detection means of the present invention, and the pinching prevention unit 52 is an aspect of the pinching prevention means of the present invention.

  The detection unit 51 performs image processing of an image captured by the camera 7 and extracts the detection line 6, and at least one of the detection lines 6 based on the image subjected to image processing by the image processing unit 51 a. And a shielding determination unit 51b for determining whether the part is in a shielding state shielded by a foreign object.

  A specific method for extracting the detection line 6 in the image processing unit 51a is not particularly limited. For example, the image captured by the camera 7 is trimmed to remove unnecessary portions, and a posterization process or a binarization process is performed. Alternatively, by performing edge detection processing, it is possible to extract a detection line 6 having a luminance different from that of the surrounding members.

  In the shielding determination unit 51b, for example, an image in an unshielded state (an image after image processing by the image processing unit 51a) is stored as an initial state image, and the initial state image and the image processing unit 51a are stored. It is configured to determine whether or not the detection line 6 is shielded by a foreign object by comparing with the image output from. The shielding determination unit 51b compares, for example, the initial state image and the image output from the image processing unit 51a, and the foreign object determination in which the difference between the edges of the detected detection lines 6 and the difference between the areas of the detection lines 6 is set in advance. It is configured to determine that it is in a shielded state when the threshold is exceeded.

  The pinch prevention unit 52 causes the drive mechanism 4 to perform a pinch prevention operation for preventing pinching by the window glass 3 when the detection unit 51 detects the shielding state when the window glass 3 is moved by the drive mechanism 4. As the pinching prevention operation, an operation for stopping the movement of the window glass 3, an operation for lowering the window glass 3 to a safe position, an operation for warning the operator by sound or light from an alarm device installed in the passenger compartment, , A combination of these operations is included.

  Further, the control unit 5 gives an instruction from the switch 24 when the detection state is detected by the detection unit 51 after the movement of the window glass 3 is instructed by the switch 24 and before the movement of the window glass 3 is started. An instruction invalidating unit 53 for invalidation is further provided. By providing the instruction invalidation unit 53, the window glass 3 does not move in the first place when the shielding state is detected, so that safety can be further improved.

  Next, specific configurations of the camera 7 and the detection line 6 will be described.

  2 is a schematic view of the door 2 as viewed from the upper side of the passenger compartment side, FIG. 3 is a schematic view of the door 2 as viewed from the lower side of the front side of the vehicle, and FIG. 4 (a) is a position including the camera 7. FIG. 4B is an enlarged view of a portion provided with the camera of FIG.

  As shown in FIGS. 2 to 4, in the vehicle window glass lifting apparatus 1 according to the present embodiment, the camera 7 forms an object image by the optical system 71 including at least one lens and the optical system 71. The optical system 71 is disposed at a position corresponding to the opening 23a formed on the upper surface S of the door trim 23 so that the optical axis C of the optical system 71 passes through the opening 23a. Yes.

  That is, in the present embodiment, the camera 7 is provided on the upper surface S of the door trim 23. Here, the upper surface S of the door trim 23 is an outer surface at the upper end portion of the door trim 23, and is a surface that is visible from above in the vertical direction. The upper surface S of the door trim 23 may be inclined with respect to the vehicle width direction (horizontal direction). In general, the position of the upper surface S of the door trim 23 is highest in the vicinity of the window glass 3, that is, in the vicinity of the outlet 21 a from which the window glass 3 is led out from the storage portion 21, and becomes lower as the distance from the window glass 3 increases. It is formed to be curved. Therefore, it can be said that the upper surface S of the door trim 23 is the outer surface (portion corresponding to the lower inner peripheral surface of the window frame 25) of the door trim 23 in the vicinity of the window glass 3 (outlet port 21a).

  The opening 23a is formed on the vehicle interior side with respect to the outlet 21a, and the optical system 71 of the camera 7 is disposed so that the optical axis C is located on the vehicle interior side of the outlet 21a. Here, in the cross-sectional view of FIG. 4A, the camera 7 is arranged so that the optical axis C of the optical system 71 coincides with the vertical direction, but the optical axis C of the optical system 71 is the vehicle with respect to the vertical direction. May be inclined in the front-rear direction or the vehicle width direction, and may be appropriately adjusted according to the mounting position of the camera 7 or a desired imaging range.

  In the present embodiment, the camera 7 is disposed in a hole 23 b provided at a front position of the vehicle on the upper surface S of the door trim 23 (a front position on the upper surface S of the door trim 23 facing the window glass 3). Here, as an example, the case where the camera 7 is provided on the upper surface S of the door trim 23 will be described. However, the position where the camera 7 is installed is not limited to this. Details of the position where the camera 7 is installed will be described later.

  The camera 7 is formed in a columnar shape as a whole, and a flange 73 protruding outward in the radial direction is formed at the tip of the camera 7. The camera 7 is inserted into the hole 23b from above the door trim 23, the flange 73 is accommodated in a recess 23c formed at the periphery of the hole 23b, and the locking claw 23d provided at the periphery below the hole 23b is inserted into the camera. 7 is fixed to the door trim 23 by engaging with a groove (not shown) provided on the door 7. In addition, although it has comprised so that the front end surface of the camera 7 and the upper surface S of the door trim 23 may correspond here, the front end surface of the camera 7 may protrude upwards from the upper surface S of the door trim 23, It may be located below the upper surface S of the door trim 23. Here, the camera 7 is arranged so that a part of the optical system 71 is located above the opening 23a. However, the camera 7 may be arranged so that the optical system 71 is located below the opening 23a. I do not care. Further, the structure for fixing the camera 7 to the door trim 23 and the insertion direction of the camera 7 are not particularly limited and can be changed as appropriate.

  The camera 7 is preferably configured such that the imaging range (viewing angle) covers the entire moving region of the window glass 3. Specifically, when the window glass 3 is completely retracted, the camera 7 has a viewing angle from the upper side in the vertical direction to the lower end of the rear standing portion 22a on the rear side of the vehicle. On the front side, it is desirable to set so as to cover the range from the upper side in the vertical direction to the lower end of the front standing portion 22b. When the window glass 3 is not completely retracted, the camera 7 has a viewing angle of the upper end (upper edge) and the rear of the window glass 3 when the window glass 3 is moved from the upper side in the vertical direction to the lowest position. On the front side of the vehicle up to the crossing position of the upright portion 22a, the intersection of the upper end (upper edge) of the window glass 3 and the front upright portion 22b when the window glass 3 is moved from the upper part in the vertical direction to the lowermost part. It is desirable to set so as to cover the range up to the position.

  As the optical system 71 of the camera 7, it is desirable to use a wide-angle lens so that foreign matter can be detected in the above-described range. Here, as the optical system 71, a super wide-angle lens having a combination of a plurality of lenses, a viewing angle of 180 ° or more in the vehicle front-rear direction, and a mounting angle of 190 ° is used.

  In addition, as the image pickup element 72, it is desirable to use an image pickup device having a fast image reading speed as much as possible in order to detect foreign matters promptly. In the present embodiment, a CMOS (Complementary MOS) image sensor is used as the image sensor 72.

  The detection line 6 is formed along at least a part of the outer edge of the window glass 3 in a state where the door 2 and the window glass 3 are closed, and is set on the vehicle interior side with respect to the window glass 3. In the present embodiment, the detection line 6 is set so as to be along the entire frame portion 22 and away from the window glass 3 toward the vehicle interior side.

  The detection line 6 only needs to be set along the window frame 25, and may be set on the door 2 side or may be set on the vehicle body side. For example, in a vehicle having a narrow distance D (see FIG. 4A) from the window glass 3 to the end (end surface) of the frame portion 22 on the vehicle interior side, the distance between the detection line 6 and the window glass 3 is secured. Therefore, the detection line 6 may be set on the vehicle body side. The detection line 6 may not be continuous, a part of the detection line 6 may be set on the door 2 side, and a part of the detection line 6 may be set on the vehicle body side.

  In the present embodiment, as an example, a case where the detection line 6 is set on the door 2 side will be described. In this case, the detection line 6 extends from the window glass 3 to the inner peripheral surface of the entire frame portion 22, that is, the entire inner peripheral surface of the rear standing portion 22 a, the front standing portion 22 b, and the upper extending portion 22 c. It is set so as to be separated inward. The inner peripheral surface of the frame portion 22 is a surface facing the window glass 3 of the frame portion 22, and is a surface on the front side of the vehicle in the rear standing portion 22a and a surface on the rear side of the vehicle in the front standing portion 22b. This is the lower surface of the upper extension 22c. That is, the inner peripheral surface of the frame portion 22 is a portion near the window glass 3 in the outer peripheral surface of the frame portion 22.

  The light source 8 is configured to irradiate the entire detection line 6. Here, the four light sources 8 are used to irradiate infrared rays to the detection line 6 set on the entire inner peripheral surface of the frame portion 22, but the number of the light sources 8 is not limited to this. Absent. Here, the light source 8 is arranged on the upper surface S of the door trim 23 in the vicinity of the camera 7, but the arrangement of the light source 8 is not limited to this. For example, the light source 8 is arranged on the inner peripheral surface of the frame portion 22. Also good.

  The detection line 6 is configured to have a luminance different from that of the surrounding members when irradiated with infrared light. For example, when the metal (sheet metal) constituting the door 2 and the rubber member (waist) on the vehicle body side are adjacent when the door 2 is closed, the boundary (that is, the boundary between the door 2 and the vehicle body) is used as the detection line 6. Can be used. In addition, when the inner peripheral surface of the frame portion 22 is made of a resin, an unevenness is provided in a part of the resin to form a line having a different infrared reflectance from the surroundings, and this line is used as the detection line 6. It is also possible to use it. However, the present invention is not limited to this, and the detection line 6 may be configured by applying a paint having a high infrared reflectance on the inner peripheral surface of the frame portion 22, and the existing brightness is different from the surroundings when the infrared light is irradiated. You may comprise from the member of. The same applies when the detection line 6 is set on the vehicle body side.

  In the present embodiment, even when the window glass 3 is descending, when the shielding state is detected, the sandwiching prevention operation is performed. This is to prevent a part of a human body such as a finger from being caught in the outlet 21a when the window glass 3 is lowered. A weather strip 30 having a lip seal 30a that is in sliding contact with the window glass 3 is provided around the outlet 21a in order to prevent water and the like from entering the storage portion 21 (internal space of the door 2). When the window glass 3 is lowered, a part of the human body such as clothing and fingers may be caught in the storage unit 21 while the lip seal 30a is involved. According to the present embodiment, it is possible to suppress such entrainment and further improve safety. Note that the pinching prevention operation that is performed when the shielding state is detected while the window glass 3 is lowered does not include the operation of lowering the window glass 3.

  Hereinafter, a surface in which the positions that are shielded when a foreign object is arranged between the optical system 71 of the camera 7 and the detection line 6 is referred to as a detection surface 9. Although the detection surface 9 depends on the specific structure of the optical system 71, the detection surface 9 is substantially the same as the surface connecting the center of the optical system 71 (the center in the vehicle width direction, the height direction, and the vehicle front-rear direction) and the detection line 6. Will be equal. Note that the entire detection surface 9 may not be a continuous surface. For example, when the detection line 6 is not continuous, the detection surface 9 is constituted by a plurality of surfaces. The detection surface 9 also includes a line in which the positions that are in a shielding state when a foreign object is arranged between the optical system 71 of the camera 7 and the detection line 6 when the detection line 6 is a point are continuous. . When the detection surface 9 is composed of a plurality of surfaces or lines, in order to ensure safety, it is desirable that the interval between adjacent surfaces or lines be at least the thickness of the infant's finger (for example, 4 mm).

  Next, the safety ensuring area and the convenience improving area will be described.

  As shown in FIG. 5, in the present embodiment, among the detection surface 9, a region having a predetermined length is set as the safety ensuring region 91 in the vertical direction downward from the upper edge U of the detection surface 9 and is detected. Of the surface 9, a region behind and below the vehicle and not overlapping with the safety ensuring region 91 is set as the convenience improving region 92, and the detection surface 9 and the inner surface of the window glass 3 in the convenience improving region 92 are set. Is set to be at least the distance d2 in the vehicle width direction between the detection surface 9 and the inner surface of the window glass 3 in the safety ensuring region 91.

  Depending on the mounting position of the camera 7 and the shape of the detection line 6, that is, depending on the shape of the detection surface 9, the distances d1 and d2 may not be constant, but in this embodiment, the safety ensuring area 91 and The distance d1 is set to be equal to or greater than the distance d2 no matter which position in the convenience improving area 92 is compared. In other words, in the present embodiment, the detection surface 9 is set so that the minimum value of the distance d1 is greater than or equal to the maximum value of the distance d2.

  The sandwiching by the window glass 3 is likely to occur in the vicinity of the dead end of the window frame 25, that is, in the upper area of the moving area of the window glass 3. Therefore, in the safety ensuring area 91 that is the area above the detection surface 9, the distance between the window glass 3 and the detection surface 9 is made sufficiently long so that foreign matter is not easily caught in the window glass 3. It becomes possible to execute the pinching prevention operation before contacting the window glass 3.

  Moreover, in the area below and below the vehicle in the movement area of the window glass 3, a part of the body such as the passenger's shoulder is likely to be close to the window glass 3, and the detection surface is located away from the window glass 3 in this area. Setting 9 will lead to a decrease in convenience. Therefore, in the present embodiment, the convenience is improved by setting the convenience improving area 92 that is the area behind and below the vehicle in the detection surface 9 in the vicinity of the window glass 3.

  In other words, in the present embodiment, a region facing a rear and lower region in the vehicle width direction in a moving region of the window glass 3 in which a part of the passenger's body is likely to approach the window glass 3 during normal use. In (Convenience improvement area 92), the detection surface 9 is set close to the window glass 3, and the upper area and the vehicle width direction of the movement area of the window glass 3 that is likely to be caught by the window glass 3 are arranged in the vehicle width direction. In the opposing area (safety ensuring area 91), the detection surface 9 is set at a position sufficiently away from the window glass 3. This makes it possible to ensure sufficient safety while ensuring convenience.

  Here, considering the case where the safety ensuring area 91 and the convenience improving area 92 are set so as to be in contact with each other, the distance d1 is set to the distance d2 or more, but more preferably, the distance d1 is set to the distance d2. It can be said that it is desirable to make it longer.

  In the present embodiment, since the distance between the window glass 3 and the detection surface 9 is shortened in the convenience improving area 92, even if the pinch prevention operation is performed after the foreign object is detected, the window glass 3 in which the foreign object is moving is detected. There is a risk of touching. However, in the lower region of the moving area of the window glass 3, the foreign object may come into contact with the moving window glass 3, but the pinching prevention operation is performed immediately after the foreign object contacts the window glass 3. Therefore, it can be said that there is a small possibility that the foreign matter is sandwiched between the window glass 3 and the upward extending portion 22c.

  Here, the assumed intrusion speed of the foreign matter, the reading speed of the camera 7, the calculation speed of the control unit 5 (the time from imaging until the judgment of the intrusion of foreign matter), and the movement of the window glass 3 of the drive mechanism 4 are stopped. In consideration of the speed (time for stopping the window glass 3), the shortest distance (the inner surface of the window glass 3) that can prevent the object from being caught before the foreign object comes into contact with the window glass 3 even if the foreign object enters. (Distance in the vehicle width direction from) is referred to as a safety ensuring distance.

  The distance d1 in the vehicle width direction between the detection surface 9 and the inner surface of the window glass 3 in the safety ensuring area 91 is set to be equal to or greater than the safety ensuring distance in the entire safety ensuring area 91. Further, the distance d2 in the vehicle width direction between the detection surface 9 and the inner surface of the window glass 3 in the convenience improving area 92 is equal to or less than the safety ensuring distance (preferably less than the safety ensuring distance) in the entire area of the convenience improving area 92. Is set as follows.

  For example, the reading speed of the camera 7 is set to 400 fps (frame / second, 1 frame 2.5 ms), and the time for judging the invasion of foreign matter after imaging is 10 ms (maximum 7.5 ms for brightness correction processing etc., detection of foreign matter) Assuming that 2.5 ms is required for processing), and the time for stopping the window glass 3 is 20 ms, the window glass 3 is stopped 30 ms after imaging. In this case, if the intrusion speed of the foreign matter is 1 m / s, the foreign matter moves 30 mm in 30 ms, so the safety ensuring distance is 30 mm. Here, the foreign substance intrusion speed is set to 1 m / s. For example, when the foreign substance intrusion speed is set to 0.5 m / s from the viewpoint of suppressing pinching of a part of an elderly person's body. The safety ensuring distance is 14.5 mm. In the above case, when the reading speed of the camera 7 is improved to 1000 fps (1 frame 1 ms), the safety ensuring distance is 24 mm. Thus, the safety ensuring distance changes according to required safety, performance of members to be used (camera 7, drive mechanism 4, etc.), and the like.

  From the viewpoint of ensuring higher safety, the length of the safety ensuring area 91 from the upper edge of the detection surface 9 (height of the safety ensuring area 91) should be made as large as possible within the range where convenience does not deteriorate. desirable. Specifically, from the actual case of pinching accident, especially when the head of a child under 3 years old is caught in the window glass 3, it is easy to lead to a serious accident, so the average value of head height of 3 years old child is 191mm Considering this, the height of the safety ensuring area 91 is desirably at least 200 mm.

  Here, the shape of the detection line 6 for realizing the safety ensuring area 91 and the convenience improving area 92 will be described.

  In the present embodiment, the rear detection line 61, which is the detection line 6 set along the outer edge of the window glass 3 on the rear side of the vehicle with the door 2 and the window glass 3 closed, is formed in a crank shape. Thus, the safety ensuring area 91 and the convenience improving area 92 are realized.

  Specifically, the rear side detection line 61 is set above the convenience improvement region 92, and is set at least below the first rear side detection line 61a and at the first rear side. And a second rear side detection line 61b set closer to the window glass 3 in the vehicle width direction than the detection line 61a.

  The distance in the vehicle width direction between the first rear side detection line 61a and the window glass 3 is a distance that is equal to or greater than the safety ensuring distance described above, and the distance in the vehicle width direction between the second rear side detection line 61b and the window glass 3 is It is considered to be less than the safety ensuring distance.

  In the present embodiment, the lower end portion of the first rear side detection line 61a and the upper end portion of the second rear side detection line 61b are set at the same height position in the vertical direction, and both of them are linearly shaped perpendicular to the vertical direction. A continuous rear detection line 61 is formed by being connected by the complementary detection unit 61c. Note that the complementary detection unit 61 c is a part of the rear side detection line 61.

  However, it is not essential that the lower end portion of the first rear side detection line 61a and the upper end portion of the second rear side detection line 61b have the same height position. For example, as shown in FIG. The lower end part of the rear side detection line 61a and the upper end part of the second rear side detection line 61b may be set so as to be separated in the vertical direction. Further, as shown in FIG. 6B, the lower end portion of the first rear side detection line 61a and the upper end portion of the second rear side detection line 61b are overlapped in the horizontal direction (so as to overlap in the vertical direction). ) It may be set.

  When the lower end portion of the first rear side detection line 61a and the upper end portion of the second rear side detection line 61b are set to be vertically separated as shown in FIG. 6A, both the rear side detection lines 61a. , 61b, it is essential to set the complementary detection unit 61c between the lower end of the first rear detection line 61a and the upper end of the second rear detection line 61b. Become. On the other hand, when the lower end portion of the first rear detection line 61a and the upper end portion of the second rear detection line 61b are overlapped as shown in FIG. 6B, the overlap length L is sufficient. It is also possible to omit the complementary detection unit 61c by setting a longer time.

  It should be noted that in the region below the portion where the two rear side detection lines 61a and 61b overlap, there is a possibility that foreign matter may invade from diagonally below. Therefore, a region where such foreign matter can enter from diagonally below is secured. Both rear detection lines 61a and 61b may be set so as not to cover the region 91.

  Moreover, the detection part 61c for a complement is not limited to the linear form which connects the lower end part of the 1st back side detection line 61a, and the upper end part of the 2nd back side detection line 61b, For example, as shown to Fig.7 (a). Alternatively, it may be set to one or more dots set between the lower end portion of the first rear side detection line 61a and the upper end portion of the second rear side detection line 61b. Further, as shown in FIG. 7B, the complementary detection unit 61c may be formed in a vertical line shape substantially parallel to the first rear side detection line 61a and the second rear side detection line 61b. In this case, for example, a part of the boundary between the waist and the sash, a part of the boundary between the door 2 and the vehicle body, or a part of the protruding part of each member such as the waist can be used as the complementary detection unit 61c. .

  When the complementary detection unit 61c is formed in a dot shape or a vertical line shape, in order to ensure safety, the interval between the complementary detection units 61c and the complementary detection unit 61c and the rear side detection lines 61a and 61b. It is desirable that the interval be at least the thickness of the infant's finger (for example, 4 mm) or less. When the complementary detection unit 61c is formed in a vertical line shape, the interval between the complementary detection units 61c and the complementary detection are set by setting the vertical overlap length of the vertical line sufficiently long. Even if the distance between the part 61c and the rear detection lines 61a and 61b is larger than the thickness of the infant's finger (for example, 4 mm), sufficient safety can be ensured.

  Next, the installation position of the camera 7 for realizing the safety ensuring area 91 and the convenience improving area 92 will be described.

  Here, as an example, the distance from the window glass 3 of the detection line 6 excluding the second rear side detection line 61b and the complementary detection unit 61c is set to the above-described safety ensuring distance d3, and the second rear side detection is performed. It is assumed that the distance of the line 61b from the window glass 3 is set to the maximum distance d4 that can ensure convenience. Here, the maximum distance d4 that can ensure convenience is the maximum distance that can ensure convenience during normal use, and is set in consideration of the shape of the door 2, the seat position, and the like. In the safety ensuring area 91, the distance in the vehicle width direction between the detection surface 9 and the window glass 3 needs to be equal to or greater than the safety ensuring distance d3 in the entire area. In the convenience improving area 92, the detection surface 9 is in the entire area. The distance in the vehicle width direction between the window glass 3 and the window glass 3 needs to be not more than the maximum distance d4 that can ensure convenience.

  As shown in FIG. 8A, first, a case where the camera 7 is installed above the lower end portion of the safety ensuring area 91, that is, at a position overlapping the safety ensuring area 91 in the vehicle width direction will be considered. In this case, when the camera 7 is installed at the position A where the distance in the vehicle width direction from the window glass 3 is equal to or greater than the safety ensuring distance d3, a line segment a connecting the camera 7 and the lower end of the second rear side detection line 61b is represented. In consideration, it can be seen that the distance between the detection surface 9 and the window glass 3 in the rear and lower region of the vehicle is longer than the maximum distance d4 that can ensure convenience. Therefore, in this case, although the safety ensuring area 91 can be realized, the convenience improving area 92 cannot be realized.

  Further, when the camera 7 is installed above the lower end of the safety ensuring area 91, if the camera 7 is installed at a position B where the distance in the vehicle width direction from the window glass 3 is less than the safety ensuring distance d3, the camera 7 And the lower end of the second rear side detection line 61b are taken into consideration, it can be seen that the distance of the detection surface 9 formed in the upper region is equal to or less than the safety ensuring distance d3. Therefore, in this case, even if the convenience improving area 92 can be realized, the safety ensuring area 91 cannot be realized.

  8A shows the case where the camera 7 is provided on the inner peripheral surface of the front window frame 25 (front standing portion 22b) as an example, but it is higher than the lower end portion of the safety ensuring region 91. If the camera 7 is installed at any position, the same result is obtained. Therefore, it can be said that the camera 7 is desirably installed below the safety ensuring area 91.

  Next, as shown in FIG. 8B, a position behind the front end of the convenience improving area 92 and a position below the upper end of the convenience improving area 92, that is, the convenience improving area 92 Consider the case where the camera 7 is installed at a position overlapping in the vehicle width direction. In this case, when the camera 7 is installed at the position C where the distance in the vehicle width direction from the window glass 3 is equal to or greater than the maximum distance d4 that can ensure convenience, the camera 7 and the lower end of the first rear side detection line 61a are connected. Considering the connecting line segment c, it can be seen that the distance between the detection surface 9 and the window glass 3 in the rear and lower region of the vehicle is longer than the maximum distance d4 that can ensure convenience. Therefore, in this case, even if the safety ensuring area 91 can be realized, the convenience improving area 92 cannot be realized. In addition, since the 2nd back side detection line 61b is set close to the window glass 3 in order to ensure convenience, installing the camera 7 in the position of the window glass 3 side rather than the 2nd back side detection line 61b. Is not realistic. Therefore, it can be said that the camera 7 is desirably installed in front of the convenience improving area 92 or above the convenience improving area 92.

  From the above verification results, when the opening 23a provided with the camera 7 is formed on the inner peripheral surface of the window frame 25, the opening 23a is at least a safety ensuring region 91 on the front side (front standing portion 22b) of the window frame 25. Or a position below the safety ensuring area 91 and above the convenience improving area 92 on the rear side of the window frame 25 (the rear standing portion 22a), or below the window frame 25 It can be said that it needs to be formed at any position on the front side of the vehicle with respect to the convenience improving region 92 in (the upper surface S of the door trim 23).

  Further, taking into consideration the shape of the door 2, the shapes of the two areas 91 and 92, the set values of the distances d3 and d4, the camera 7 is installed at an appropriate position where both the areas 91 and 92 can be realized. Good.

  In the illustrated example, on the front side (front standing portion 22b) of the window frame 25, the distance below the safety ensuring area 91 and the distance in the vehicle width direction from the window glass 3 can ensure the convenience. An area where the line segment connecting the camera 7 (center of the optical system 71) and the lower end of the first rear side detection line 61a overlaps the set convenience improving area 92 and the vehicle width direction is equal to or less than the distance d4. It is necessary to provide the camera 7 at a position that does not cross. The rear side of the window frame 25 (the rear standing portion 22a) is below the safety ensuring area 91 and above the convenience improving area 92, and in the vehicle width direction from the window glass 3. It is necessary to provide the camera 7 at a position where the distance is equal to or less than the maximum distance d4 that can ensure convenience. Further, on the lower side of the window frame 25 (the upper surface S of the door trim 23), the vehicle is on the front side of the convenience improving region 92, and the distance from the window glass 3 in the vehicle width direction can ensure convenience. An area where the line segment connecting the camera 7 (the center of the optical system 71) and the lower end of the first rear side detection line 61a overlaps with the convenience improving area 92 to be set and the vehicle width direction, which is not more than the maximum distance d4. It is necessary to provide the camera 7 at a position that does not cross. When the convenience improving area 92 is set to be wide, there may be a case where the camera 7 cannot be installed on the lower window frame 25 (the upper surface S of the door trim 23).

  In the present embodiment, the area behind and below the vehicle in the detection surface 9 is set as the convenience improvement area 92, but the entire area below the detection surface 9 may be set as the convenience improvement area 92. Good. Moreover, the shape of the safety ensuring area | region 91 and the convenience improvement area | region 92 is not limited to the thing of illustration, and can be set suitably.

  Next, a control flow of the vehicle window glass lifting apparatus 1 will be described.

  As shown in FIG. 9, in the vehicle window glass elevating device 1, first, in step S <b> 1, the control unit 5 determines whether a signal is input from the switch 24. If NO is determined in step S1, the control unit 5 turns off the power of the camera 7 (or continues the power-off state) in step S2, and returns to step S1. Although not shown, when the light source 8 is turned on, the light source 8 is turned off in step S2.

  If YES is determined in step S1, the control unit 5 turns on the power of the camera 7 (or continues the power-on state) in step S3, and proceeds to step S4. Although illustration is omitted here, when the illuminance for imaging with the camera 7 is insufficient, the power source of the light source 8 is turned on in step S3.

  In step S <b> 4, the detection unit 51 (the image processing unit 51 a and the shielding state determination unit 51 b) performs processing for detecting the shielding state (shielding state detection processing) based on the image captured by the camera 7. Thereafter, in step S <b> 5, the instruction invalidation unit 53 determines whether the detection unit 51 has detected a shielding state.

  If it is determined YES in step S5, the instruction invalidation unit 53 determines that there is a possibility of being caught by the window glass 3, and does not move the window glass 3 (that is, invalidates the signal from the switch 24). Return to S1.

  If NO is determined in step S5, in step S6, the control unit 5 determines that the signal input from the switch 24 is a first-stage click signal (down-side first-stage click signal or ascending-side first-stage click). Signal).

  If YES is determined in step S6, the control unit 5 controls the drive mechanism 4 to control the movement of the window glass 3 in step S7.

  Thereafter, in step S <b> 8, the detection unit 51 performs a process of detecting the shielding state (shielding state detection process) based on the image captured by the camera 7. Thereafter, in step S <b> 9, the pinching prevention unit 52 determines whether the detection unit 51 has detected the shielding state.

  If YES is determined in step S9, there is a risk of pinching by the window glass 3, and therefore, in step S10, the pinching prevention unit 52 stops the movement of the window glass 3, or the window glass 3 is positioned at a safe position. The trapping prevention operation such as lowering is performed. Then, after the control part 5 complete | finishes the movement of the window glass 3 in step S18, it returns to step S2. As described above, in the present embodiment, when the shielding state is detected while the first-stage click signal is being input from the switch 24, the movement of the window glass 3 is terminated after the pinching prevention operation is performed.

  If it is determined NO in step S9, there is no possibility of being caught by the window glass 3, so the control unit 5 determines whether a signal is input from the switch 24 in step S11. When it is determined NO in step S11, the operation of the switch 24 has been completed. Therefore, after the control unit 5 finishes moving the window glass 3 in step S18, the process returns to step S2. If YES is determined in step S11, the process returns to step S6, and the movement of the window glass 3 is continued.

  On the other hand, if NO is determined in step S6, that is, if the second stage click signal (the lower side second stage click signal or the upward second stage click signal) is input from the switch 24, in step S12, The control unit 5 controls the drive mechanism 4 to control the movement of the window glass 3.

  Thereafter, in step S <b> 13, the detection unit 51 performs a process of detecting the shielding state (shielding state detection process) based on the image captured by the camera 7. Thereafter, in step S <b> 14, the pinching prevention unit 52 determines whether the detection unit 51 has detected the shielding state.

  If YES is determined in step S14, there is a possibility of pinching by the window glass 3. Therefore, in step S15, the pinching prevention unit 52 performs the pinching prevention operation. Thereafter, after the movement of the window glass 3 is finished in step S18, the process returns to step S2. That is, in this embodiment, when the second stage click signal is input from the switch 24 and the shielding state is detected when the window glass 3 is moved, the window glass 3 is moved after the pinch prevention operation is performed. End the move.

  If NO is determined in step S14, there is no possibility of pinching by the window glass 3, so in step S16, the control unit 5 determines whether the window glass 3 has been moved to the end (upper end or lower end position). To do. If YES is determined in step S16, the control unit 5 returns to step S2 after the control unit 5 finishes moving the window glass 3 in step S18. Note that the position information of the window glass 3 may be acquired by using a rotation pulse generated by using a Hall IC incorporated in the motor 41 or a current ripple.

  If NO is determined in step S16, it is determined in step S17 whether a new signal is input from the switch 24 (whether a new signal is input after the second-stage click signal is input). If YES is determined in the step S17, the process returns to the step S6. If NO is determined in step S17, the process returns to step S12, and the movement of the window glass 3 is continued. That is, when the second stage click signal is input, the window glass 3 is moved until the shielding state is detected, the window glass 3 moves to the end, or a new signal is input from the switch 24. continue.

(Operation and effect of the embodiment)
As described above, in the vehicle window glass elevating device 1 according to the present embodiment, a region having a predetermined length in the detection surface 9 from the upper edge of the detection surface 9 vertically downward is the safety ensuring region 91. Of the detection surface 9, the region behind and below the vehicle and not overlapping the safety ensuring region 91 is set as the convenience improving region 92, and the detection surface 9 in the convenience improving region 92 is A distance d2 in the vehicle width direction with respect to the inner surface of the window glass 3 is at least equal to or less than a distance d1 in the vehicle width direction between the detection surface 9 and the inner surface of the window glass 3 in the safety ensuring region 91.

  With this configuration, the distance between the window glass 3 and the detection surface 9 is increased in the upper region where pinching by the window glass 3 is likely to occur, and the pinching prevention operation is executed before the foreign object comes into contact. It becomes possible. Further, in a region behind and below the vehicle where a part of the passenger's body is likely to be close to the window glass 3 during normal use, the distance between the window glass 3 and the detection surface 9 is shortened. Even though there is no fear of pinching due to, the pinching prevention operation is performed, and it is possible to suppress the trouble that the window glass 3 cannot be moved when it is desired to move and to improve convenience. As a result, even if the door trim 23 is thin, such as a compact car having a small vehicle size, it is possible to achieve both safety and convenience.
