Description

[Technical Field]

[0001] The present invention relates to an opening and closing control system. [Background technology]

[0002] Conventionally, one technique for controlling the opening and closing of an opening / closing body that constitutes a sliding door installed at an opening in a building has been disclosed in which, when the opening / closing body is moved from either a fully closed position in which the opening is fully closed by the opening / closing body to a fully open position in which the opening is fully opened, the opening / closing body is first moved open and closed at high speed, and when a sensor detects that the opening / closing body has reached a high-speed braking point, the speed of the opening / closing movement of the opening / closing body is decelerated via a motor, and the opening / closing body is stopped at the other of the fully closed position or the fully open position (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-127152 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional technology, as described above, when the sensor detects that the opening-closing body has reached the high-speed braking point, the speed of the opening-closing body's opening and closing movement is merely slowed down, so if, for example, an abnormality occurs in the sensor and the sensor does not detect that the opening-closing body has reached the high-speed braking point, the opening-closing body will continue to open and close at high speed, which could cause a collision between the opening-closing body and people in or near the opening, making it difficult to ensure the safety of those people. Therefore, there is room for improvement from the perspective of increasing safety when using a sliding door.

[0005] The present invention is intended to solve the problems in the conventional technology described above, and has an object to provide an opening and closing control system that can improve safety when using a sliding door. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems and achieve the object, the opening / closing control system according to claim 1 is an opening / closing body constituting a sliding door provided at an opening of a building, and is an opening / closing control system for controlling opening / closing movement of the opening / closing body that opens and closes the opening, comprising: an opening-side detection means that, when the opening / closing body is moved to open, is used to safely stop the opening movement at a fully open position that is a position corresponding to a state in which the opening is fully opened by the opening / closing body; a closing-side detection means that, when the opening / closing body is moved to close, is used to safely stop the closing movement at a fully closed position that is a position corresponding to a state in which the opening is fully closed by the opening / closing body; and an opening / closing control means that controls the opening / closing movement of the opening / closing body based on the detection results of the opening-side detection means and the detection results of the closing-side detection means. the opening side detection means comprises opening side deceleration position detection means which detects whether the opening / closing body has reached an opening side deceleration position which is located just before the fully open position, and the closing side detection means comprises closing side deceleration position detection means which detects whether the opening / closing body has reached a closing side deceleration position which is located just before the fully closed position, and when the opening side deceleration position detection means detects that the opening / closing body has reached the opening side deceleration position and the closing side deceleration position detection means detects that the opening / closing body has reached the closing side deceleration position, the opening / closing control means determines that an abnormality has occurred in the opening side deceleration position detection means and / or the closing side deceleration position detection means, and performs abnormality treatment control which is control related to treatment for the determined abnormality.

[0007] The opening / closing control system of claim 2 is the opening / closing control system of claim 1, in which the abnormality treatment control performed when the opening / closing body is moving in an open position includes a first abnormality restriction control that restricts the opening / closing movement of the opening / closing body after moving the opening / closing body in an open position until the return timing arrives for returning to the state before the abnormality occurred.

[0008] The opening / closing control system of claim 3 is the opening / closing control system of claim 1, in which the abnormality treatment control performed when the opening / closing body is moving in the closed position includes a second abnormality restriction control that restricts the opening / closing movement of the opening / closing body after moving the opening / closing body in the closed position to the fully closed position until the return timing arrives for returning to the state before the abnormality occurred.

[0009] The opening / closing control system of claim 4 is an opening / closing control system of any one of claims 1 to 3, wherein the opening side detection means comprises a fully open position detection means that detects whether the opening / closing body has reached the fully open position, and the closing side detection means comprises a fully closed position detection means that detects whether the opening / closing body has reached the fully closed position, and the opening / closing control means performs the abnormality treatment control when the fully open position detection means detects that the opening / closing body has reached the fully open position and the fully closed position detection means detects that the opening / closing body has reached the fully closed position.

[0010] The opening / closing control system according to claim 5 is an opening / closing body constituting a sliding door provided at an opening of a building, and is an opening / closing control system for controlling opening / closing movement of the opening / closing body that opens and closes the opening, and comprises: opening-side detection means used to safely stop the opening movement at a fully open position that corresponds to a state in which the opening is fully opened by the opening / closing body when the opening / closing body is moved to open; closing-side detection means used to safely stop the closing movement at a fully closed position that corresponds to a state in which the opening is fully closed by the opening / closing body when the opening / closing body is moved to close; and opening / closing control means that controls the opening / closing movement of the opening / closing body based on the detection results of the opening-side detection means and the detection results of the closing-side detection means, and The closing side detection means includes a first detection means that detects whether the opening / closing body has reached the fully open position or the fully closed position, and a second detection means that detects whether the opening / closing body has reached the fully open position or the deceleration position located just before the fully closed position. If the first detection means detects that the opening / closing body has reached the fully open position or the fully closed position, but the second detection means does not detect that the opening / closing body has reached the fully open position or the deceleration position located just before the fully closed position detected as having been reached by the first detection means, the opening / closing control means determines that an abnormality has occurred in the first detection means and / or the second detection means, and performs abnormality treatment control, which is control related to treatment for the determined abnormality.

[0011] The opening / closing control system of claim 6 is the opening / closing control system of claim 5, wherein the first detection means includes a fully open position detection means that detects whether the opening / closing body has reached the fully open position, and a fully closed position detection means that detects whether the opening / closing body has reached the fully closed position, and the opening / closing control means performs the abnormality treatment control when the fully open position detection means detects that the opening / closing body has reached the fully open position and the fully closed position detection means detects that the opening / closing body has reached the fully closed position. [Effects of the Invention]

[0012] According to the opening / closing control system of claim 1, when the opening-side deceleration position detection means detects that the opening / closing body has reached the opening-side deceleration position and the closing-side deceleration position detection means detects that the opening / closing body has reached the closing-side deceleration position, the opening / closing control means determines that an abnormality has occurred in the opening-side deceleration position detection means and / or the closing-side deceleration position detection means and performs abnormality treatment control, so that abnormality treatment control can be performed when an abnormality has occurred in the opening-side deceleration position detection means and / or the closing-side deceleration position detection means. Therefore, treatment can be taken quickly for the abnormality, and safety during use of the sliding door can be improved.

[0013] According to the opening / closing control system described in claim 2, the abnormality treatment control performed when the opening / closing body is moving in the open position includes the first abnormality restriction control, so that if an abnormality occurs in the opening side deceleration position detection means or / and the closing side deceleration position detection means during the opening movement of the opening / closing body, the first abnormality restriction control can be performed, and it is possible to avoid the opening / closing body moving in an unusual manner until the return timing arrives.

[0014] According to the opening / closing control system described in claim 3, the abnormality treatment control performed when the opening / closing body is moving in the closing direction includes the second abnormality restriction control, so that if an abnormality occurs in the opening side deceleration position detection means and / or the closing side deceleration position detection means during the closing movement of the opening / closing body, the second abnormality restriction control can be performed, thereby preventing the opening / closing body from moving in an unusual manner until the return timing arrives.

[0015] According to the opening / closing control system of claim 4, the opening / closing control means performs abnormality treatment control when the fully open position detection means detects that the opening / closing body has reached the fully open position and the fully closed position detection means detects that the opening / closing body has reached the fully closed position, so abnormality treatment control can be performed when an abnormality occurs in the fully open position detection means and / or the fully closed position detection means. Therefore, treatment can be taken quickly in response to the abnormality, further improving safety when using the sliding door.

[0016] According to the opening / closing control system of claim 5, when the first detection means detects that the opening / closing body has reached the fully open position or the fully closed position, but the second detection means does not detect that the opening / closing body has reached a deceleration position located before the fully open position or the fully closed position detected by the first detection means, the opening / closing control means determines that an abnormality has occurred in the first detection means and / or the second detection means, and performs abnormality treatment control, so that abnormality treatment control can be performed when an abnormality has occurred in the first detection means and / or the second detection means. Therefore, treatment for the abnormality can be taken quickly, and safety when using the sliding door can be improved.

[0017] According to the opening / closing control system of claim 6, the opening / closing control means performs abnormality treatment control when the fully open position detection means detects that the opening / closing body has reached the fully open position and the fully closed position detection means detects that the opening / closing body has reached the fully closed position, so abnormality treatment control can be performed when an abnormality occurs in the fully open position detection means and / or the fully closed position detection means. Therefore, treatment can be taken quickly in response to the abnormality, further improving safety when using the sliding door. [Brief explanation of the drawings]

[0019] An embodiment of the opening / closing control system according to the present invention will be described in detail below with reference to the accompanying drawings. First, [I] the basic concept of the embodiment will be described, then [II] specific details of the embodiment will be described, and finally, [III] modifications to the embodiment will be described. However, the present invention is not limited to the embodiment.

[0020] [I] Basic Concept of the Embodiment First, the basic concept of the embodiment will be described.

[0021] The embodiment generally relates to an opening / closing control system for controlling the opening and closing movement of an opening / closing body that constitutes a sliding door provided at an opening of a building and that opens and closes the opening.

[0022] Here, the specific type of "building" is arbitrary, but the concept includes, for example, factory facilities, apartment complexes such as apartments and condominiums, detached houses, office buildings, commercial facilities, and public facilities.

[0023] Furthermore, an "opening in a building" is an opening formed in a part of the building's framework (for example, a wall, floor, ceiling, etc.) for installing an entrance or window.

[0024] Furthermore, the "open / closed state of the opening / closing body" is a concept that includes, for example, a "fully closed state," a "fully open state," and a "half-open state."

[0025] Of these, the "fully closed state" refers to a state in which the opening is fully closed by the opening / closing body, and in the embodiment, the position of the opening / closing body in the fully closed state is referred to as the "fully closed position."

[0026] Further, the "fully open state" refers to a state in which the opening is fully opened by the opening / closing body, and in the embodiment, the position of the opening / closing body in the fully open state is referred to as the "fully open position."

[0027] Furthermore, the "half-open state" refers to a state in which the opening / closing body is positioned between the fully closed position and the fully open position, and the position of the opening / closing body in the half-open state is referred to as the "half-open position."

[0028] Furthermore, the specific structure of the "sliding door" is arbitrary, and it can be configured as, for example, a sliding door, a single sliding door, a double sliding door, or a double single sliding door.

[0029] In the following embodiments, a case will be described in which the sliding door is an electric sliding door that opens and closes from left to right and is a single-sliding door provided at the entrance of a building such as a factory facility.

[0030] [II] Specific details of the embodiment Next, specific details of the embodiment will be described.

[0031] (composition) First, the configuration of a sliding door 1 to which an opening / closing control system according to an embodiment is applied will be described.

[0032] In the following explanation, the X direction in FIG. 1 will be referred to as the left-right direction of the sliding door 1 (-X direction is the left direction of the sliding door 1, and +X direction is the right direction of the sliding door 1), the Y direction in FIG. 1 will be referred to as the up-down direction of the sliding door 1 (+Y direction is the up direction of the sliding door 1, and -Y direction is the down direction of the sliding door 1), and the direction perpendicular to the X and Y directions will be referred to as the front-to-back direction (the direction leading to the front side of the paper in FIG. 1 is the front direction of the sliding door 1, and the direction leading to the back side of the paper in FIG. 1 is the rear direction of the sliding door 1).

[0033] The sliding door 1 is used to restrict or limit access to an opening 3 in a building. As shown in Figs. 1 and 2, the sliding door 1 generally comprises a frame 10, an opening / closing body 20, a drive unit 30, and an opening / closing control system 40.

[0034] It should be noted that the configuration of the sliding door 1 that is not specifically mentioned is the same as that of a conventional electric sliding door, and therefore the description thereof will be omitted.

[0035] Furthermore, the components that make up the sliding door 1 may be connected in any manner, but in this embodiment, they are set as follows.

[0036] That is, the control unit 50 of the opening / closing control system 40 described later is electrically connected via wiring 4 to each of the drive unit 30, the operation unit 41 of the opening / closing control system 40 described later, the fully closed position detection unit 42, the fully open position detection unit 43, the closing side deceleration position detection unit 44, the opening side deceleration position detection unit 45, the first obstacle detection unit 46, the second obstacle detection unit 47, and the opening / closing output unit 48.

[0037] This allows communication or power supply to be performed directly or indirectly between the control unit 50 described below and the drive unit 30, the operation unit 41 described below, the fully closed position detection unit 42 described below, the fully open position detection unit 43 described below, the closing side deceleration position detection unit 44 described below, the opening side deceleration position detection unit 45 described below, the first obstacle detection unit 46 described below, the second obstacle detection unit 47 described below, or the opening / closing output unit 48 described below.

[0038] The method of attaching (or connecting) the various components that make up the sliding door 1 to each other is arbitrary, but for example, a method is used in which the component on the attachment side is attached (or connected) to the component on the other side through an attachment hole (for example, a rivet hole, a screw hole, a screw hole, etc.) formed in the component on the attachment side or the component on the other side using a fastener (for example, a rivet, a mounting screw, a screw, etc.), welding, an adhesive, double-sided tape, etc.

[0039] (Configuration - Frame) The frame 10 is installed on the periphery of an opening 3 formed in a building frame 2 (for example, an exterior wall or a floor, etc.). The frame 10 is formed by combining multiple frame materials (for example, frame materials made of steel (steel, stainless steel, etc.)).

[0040] Specifically, as shown in Figure 1, the multiple frame members are composed of a left vertical frame 11, a right vertical frame 14, a lower horizontal frame 12, and a crossbeam 13. The left vertical frame 11, the right vertical frame 14, the lower horizontal frame 12, and the crossbeam 13 are each directly fixed to the building frame 2 around the periphery of the opening 3 by a known method.

[0041] (Configuration - Frame - No eyelets) Of these, the transom 13 is used to store each part of the sliding door 1. As shown in Fig. 1, the transom 13 is attached to the building frame 2 (for example, an outer wall or the like).

[0042] The specific configuration of the interlock 13 is arbitrary, but in this embodiment, it is configured as follows.

[0043] That is, the transom 13 is shaped as a long hollow body extending substantially along the left-right direction, and the bottom surface of the hollow body is open.

[0044] The length of the interlock 13 in the left-right direction is set to a length that can accommodate the drive unit 30, and specifically, is set to be longer than the length of the drive unit 30 in the left-right direction.

[0045] In addition, the length of the interlock 13 in the front-to-back direction is set to be longer than the length of the opening-closing body 20 in the front-to-back direction, and may be set to, for example, approximately three to five times the length of the opening-closing body 20 in the front-to-back direction.

[0046] The vertical length of the interlock 13 is set to be longer than the vertical length of the drive unit 30.

[0047] In addition, the transom 13 is installed so that its left end is located to the left of the opening / closing body 20 in the fully closed state, and its right end is located to the right of the opening / closing body 20 in the fully open state.

[0048] The method of forming the interlock 13 is to connect a plurality of bent steel plate-like bodies to each other with fixtures such as screws or mounting screws, thereby forming the interlock 13.

[0049] With this configuration, as shown in Figure 1, the interior of the interceptor 13 can accommodate the drive unit 30, the fully closed position detection unit 42 of the opening / closing control system 40 described later, the fully open position detection unit 43, the closing side deceleration position detection unit 44, the opening side deceleration position detection unit 45, the second obstacle detection unit 47, and the control unit 50.

[0050] (Configuration - Frame - Other configurations) The other configurations of the frame portion 10 are optional, but in this embodiment, as shown in Figure 1, the frame portion 10 further includes a guide rail 15, a closing side door stop portion 16, and an opening side door stop portion 17.

[0051] (Configuration - Frame - Other configurations - Guide rail) The guide rail 15 guides the opening / closing body 20 to move in the opening / closing direction (left-right direction in the embodiment) of the opening 3. The guide rail 15 is an elongated body formed so that the cross section along the YZ plane has a substantially convex (or substantially U-shaped) shape, and is disposed on the underside of the crossbar 13 and on the floor of the building so that the longitudinal direction of the guide rail 15 is substantially along the left-right direction, and is fixed to the crossbar 13 or the floor of the building by fixtures or the like.

[0052] In the following, where necessary, the guide rail 15 provided on the interlock 13 (not shown) will be referred to as the "upper guide rail," and the guide rail 15a provided on the floor surface of the building will be referred to as the "lower guide rail 15a."

[0053] Furthermore, the specific configuration of the guide rail 15 is arbitrary, but in this embodiment, it is configured as follows.

[0054] That is, the length of the guide rail 15 in the left-right direction is set to a length that allows the opening / closing body 20 to be moved from the fully open position to the fully closed position. Specifically, the length is set to be longer than the left-right length of the opening 3, and may be set to, for example, about twice the left-right length of the opening / closing body 20.

[0055] The length of the guide rail 15 in the front-rear direction is set to be approximately the same as or longer than the length of the opening / closing body 20 in the front-rear direction.

[0056] Regarding the method of installing the upper guide rail, the upper guide rail is installed on the lintel 13 at a position outside the building from the lower horizontal frame 12 so that the left end of the upper guide rail is positioned approximately at the same position as the left end of the opening / closing body 20 in the fully closed state, and the right end of the upper guide rail is positioned approximately at the same position as the opening / closing body 20 in the fully open state.

[0057] Regarding the method of installing the lower guide rail 15a, the lower guide rail 15a is installed on the floor of the building so that, at a position outside the building beyond the lower horizontal frame 12, the left end of the lower guide rail 15a is positioned approximately at the same position as the left end of the opening / closing body 20 in the fully closed state, and the right end of the lower guide rail 15a is positioned approximately at the same position as the opening / closing body 20 in the fully open state.

[0058] (Configuration - Frame - Other configurations - Closing side door stop) The closing side door stop 16 is intended to restrict the closing movement of the opening / closing body 20 beyond the fully closed position. This closing side door stop 16 is made up of a known door stop member and is provided on the left vertical frame 11 as shown in Figures 1 and 2.

[0059] Specifically, the closing side door stop portion 16 is provided over approximately the entire length in the vertical direction of the right end face of the left vertical frame 11, and is provided in a position where the closing side door stop portion 16 and the opening / closing body 20 can come into contact with each other in the fully closed state, and is connected to the left vertical frame 11 by a fixing device or the like.

[0060] (Configuration - Frame - Other configurations - Open side door stop)

[0061] The opening-side door stop portion 17 is intended to restrict the opening / closing body 20 from moving beyond the fully open position. This opening-side door stop portion 17 is made up of a known door stop member, and is provided on the lower guide rail 15a as shown in Figure 1.

[0062] Specifically, the open side door stop portion 17 is arranged to protrude upward from the right end portion of the lower guide rail 15a, and is arranged in a position where the open side door stop portion 17 and the opening / closing body 20 can come into contact with each other when the door is fully open, and is connected to the lower guide rail 15a by a fixing device or welding, etc.

[0063] The specific configuration of the open-side door stop portion 17 is arbitrary, but in the embodiment, the vertical length of the open-side door stop portion 17 is set to be longer than the vertical length of the lower guide rail 15a, and may be set to, for example, approximately two to three times the vertical length of the lower guide rail 15a.

[0064] (Configuration - Opening and closing body) The opening / closing body 20 is configured to switch the opening / closing state of the opening / closing body 20 to a fully open state, a fully closed state, or a half-open state by moving the opening / closing body 20 substantially along the opening / closing direction (left / right direction) using the drive unit 30. The opening / closing body 20 is configured using, for example, a known one-way pull opening / closing body, and is provided at a position where the opening / closing state of the opening / closing body 20 can be switched to a fully open state, a fully closed state, or a half-open state.

[0065] The opening / closing body 20 may be installed in any manner, but in this embodiment, it is installed as follows.

[0066] That is, first, a guided member (e.g., a guide roller, etc.) not shown is attached to the upper end of the opening / closing body 20, and this guided member is arranged slidably on the upper guide rail, thereby hanging the opening / closing body 20 from the upper guide rail.

[0067] Next, a guided member (e.g., a slider, etc.) not shown is attached to the lower end of the opening / closing body 20, and this guided member is inserted into the interior of the lower guide rail 15a through the U-shaped open end of the lower guide rail 15a, thereby fitting it into the upper guide rail and the lower guide rail 15a, thereby installing the opening / closing body 20.

[0068] This installation method allows the opening / closing body 20 to slide inside the upper guide rail and lower guide rail 15a in the left-right direction, and can prevent it from falling outside the upper guide rail or lower guide rail 15a in the front-to-back direction.

[0069] (Configuration - Drive unit) The drive unit 30 is a drive means for electrically moving the opening / closing body 20 to open and close. The drive unit 30 is provided inside the transom 13 and is configured using, for example, a known drive means for a sliding door that has a deceleration function.

[0070] Specifically, as shown in FIG. 1, the drive unit 30 includes an endless belt 31 connected to the opening / closing body 20, a drive pulley 32 and a driven pulley 33 arranged inside the endless belt 31 to rotate the endless belt 31, and a motor 34 to rotate the drive pulley 32.

[0071] With this configuration, the opening / closing body 20 can be moved to open or close by rotating the drive pulley 32 with the motor .

[0072] (Configuration - Opening and closing control system) The opening / closing control system 40 is a system for controlling the opening / closing movement of the opening / closing body 20, and as shown in Figure 1, it is equipped with an operating unit 41, a closing side detection unit 40a, an opening side detection unit 40b, a first obstacle detection unit 46, a second obstacle detection unit 47, an opening / closing output unit 48, and a control unit 50.

[0073] (Configuration - Opening and closing control system - Operation unit) The operation unit 41 is an operation means that receives operation input to the opening and closing control system 40. The operation unit 41 is attached to the outer surface and inner surface of the body 2 in the vicinity of the opening 3, as shown in FIG.

[0074] The operating unit 41 is configured using, for example, a known wired operating device, etc. Specifically, it includes an open button that electrically moves the opening / closing body 20 to the open position, a close button that electrically moves the opening / closing body 20 to the closed position, and a stop button that stops the electrically moved closing or opening position (all of which are not shown).

[0075] Furthermore, the specific operation of the operating unit 41 is arbitrary, but in the embodiment, when the open button, close button, or stop button is pressed by the user, an operation signal (i.e., open signal, close signal, stop signal) corresponding to the pressed button is output to the drive unit 30 via the control unit 50, so that the drive unit 30 can electrically move the opening / closing body 20 to open or close, or electrically stop the opening / closing movement of the opening / closing body 20.

[0076] (Configuration - Opening and closing control system - Closing side detection unit) The closing side detection unit 40a is a closing side detection means used to safely stop the closing movement at the fully closed position when the opening / closing body 20 is moved to the closing position, and as shown in Figure 1, it is equipped with a fully closed position detection unit 42 and a closing side deceleration position detection unit 44.

[0077] (Configuration - Opening and closing control system - Closing side detection unit - Fully closed position detection unit) The fully closed position detector 42 is a fully closed position detector that detects whether the opening / closing body 20 has reached the fully closed position, and is also a first detector. The fully closed position detector 42 is configured using, for example, a known position detection sensor (one example is a self-holding proximity switch (magnetic proximity switch)), and is provided inside the interlock 13 at a position corresponding to or near the end of the opening 3 in the closing direction (the left end in FIG. 1), as shown in FIG.

[0078] Furthermore, the detection operation of the fully closed position detection unit 42 is optional, but in this embodiment it operates as follows.

[0079] That is, when the opening / closing body 20 is in the fully closed position, a magnet portion (not shown) provided at the door-tip end of the upper end of the opening / closing body 20 or in the vicinity thereof acts on the fully closed position detection unit 42, causing the operation state of the fully closed position detection unit 42 to turn on, and the fully closed position detection unit 42 outputs a signal indicating that the opening / closing body 20 has reached the fully closed position (hereinafter referred to as the "fully closed position detection signal"). Note that as long as the operation state of the fully closed position detection unit 42 remains on, the fully closed position detection unit 42 continues to output the fully closed position detection signal.

[0080] On the other hand, when the opening / closing body 20 is not positioned in the fully closed position, the magnet portion provided on the opening / closing body 20 does not act on the fully closed position detection unit 42, causing the operating state of the fully closed position detection unit 42 to be turned off, and therefore the fully closed position detection unit 42 does not output a fully closed position detection signal.

[0081] (Configuration - Opening and closing control system - Closing side detection unit - Closing side deceleration position detection unit) The closing side deceleration position detection unit 44 is a closing side deceleration position detection means that detects whether the opening / closing body 20 has reached the closing side deceleration position, and is also a second detection means.

[0082] Here, the "closing side deceleration position" refers to a deceleration position located just before the fully closed position, and means a position that triggers a deceleration of the closing movement of the opening / closing body 20. In the embodiment, this is described as a position that is a predetermined distance (e.g., about 100 mm) away from the fully closed position toward the opening direction.

[0083] This closing side deceleration position detection unit 44 is constructed using, for example, a known position detection sensor (one example is a self-holding proximity switch (magnetic proximity switch)), and is provided inside the interlock 13 in a position adjacent to the fully closed position detection unit 42, as shown in Figure 1.

[0084] Specifically, the closing side deceleration position detection unit 44 is positioned such that when the opening / closing body 20 is positioned in the range from the closing side deceleration position to the fully closed position, the magnet portion provided on the opening / closing body 20 acts on the closing side deceleration position detection unit 44, causing the operating state of the closing side deceleration position detection unit 44 to be in the on state.

[0085] However, this is not limited to this, and for example, the closing side deceleration position detection unit 44 may be located in a position where the operating state of the closing side deceleration position detection unit 44 is turned on when the magnet portion provided on the opening / closing body 20 acts on the closing side deceleration position detection unit 44 only when the opening / closing body 20 is located in the closing side deceleration position.

[0086] Furthermore, the detection operation of the closing side deceleration position detection unit 44 is optional, but in this embodiment it operates as follows.

[0087] That is, when the opening-closing body 20 is located at the closing side deceleration position, the magnet portion provided in the opening-closing body 20 acts on the closing side deceleration position detection unit 44, causing the operating state of the closing side deceleration position detection unit 44 to turn on, and the closing side deceleration position detection unit 44 outputs a signal indicating that the opening-closing body 20 has reached the closing side deceleration position (hereinafter referred to as the "closing side deceleration position detection signal"). Note that as long as the operating state of the closing side deceleration position detection unit 44 remains on, the closing side deceleration position detection unit 44 continues to output the closing side deceleration position detection signal.

[0088] On the other hand, when the opening / closing body 20 is not positioned in the closing side deceleration position (except in the range from the closing side deceleration position to the fully closed position), the magnet portion provided on the opening / closing body 20 does not act on the closing side deceleration position detection unit 44, causing the operating state of the closing side deceleration position detection unit 44 to be in the off state, and therefore the closing side deceleration position detection unit 44 does not output a closing side deceleration position detection signal.

[0089] (Configuration - Opening and closing control system - Opening side detection unit) The opening side detection unit 40b is an opening side detection means used to safely stop the opening movement at the fully open position when the opening / closing body 20 is moved to the open position, and as shown in Figure 1, it is equipped with a fully open position detection unit 43 and an opening side deceleration position detection unit 45.

[0090] (Configuration - Opening and closing control system - Open side detection unit - Fully open position detection unit) The fully open position detector 43 is a fully open position detector that detects whether the opening / closing body 20 has reached the fully open position, and is also a first detector. The fully open position detector 43 is configured using, for example, a known position detection sensor (one example is a self-holding proximity switch (magnetic proximity switch)), and is provided inside the interlock 13 at a position corresponding to or near the end of the opening 3 in the opening direction (the right end in FIG. 1), as shown in FIG.

[0091] Further, the detection operation of the fully open position detection unit 43 is optional, but in this embodiment it operates as follows.

[0092] That is, when the opening-closing body 20 is in the fully open position, the magnet portion provided in the opening-closing body 20 acts on the fully open position detector 43, causing the fully open position detector 43 to turn on, and output a signal indicating that the opening-closing body 20 has reached the fully open position (hereinafter referred to as the "fully open position detection signal"). Note that as long as the fully open position detector 43 maintains its on state, the fully open position detector 43 continues to output the fully open position detection signal.

[0093] On the other hand, when the opening / closing body 20 is not positioned in the fully open position, the magnet portion provided on the opening / closing body 20 does not act on the fully open position detection unit 43, causing the operating state of the fully open position detection unit 43 to be turned off, and therefore the fully open position detection unit 43 does not output a fully open position detection signal.

[0094] (Configuration - Opening / closing control system - Opening side detection unit - Opening side deceleration position detection unit) The opening-side deceleration position detection unit 45 is an opening-side deceleration position detection means that detects whether or not the opening-closing body 20 has reached the opening-side deceleration position, and is also a second detection means.

[0095] Here, the "opening side deceleration position" refers to a deceleration position located just before the fully open position, and means a position that triggers a deceleration of the opening movement of the opening / closing body 20. In the embodiment, this is described as a position that is a predetermined distance (e.g., about 100 mm) away from the fully open position toward the closing direction.

[0096] This open side deceleration position detection unit 45 is constructed using, for example, a known position detection sensor (one example is a self-holding proximity switch (magnetic proximity switch)), and is provided inside the interlock 13 at a position corresponding to the vicinity of the fully open position detection unit 43, as shown in Figure 1.

[0097] Specifically, the opening side deceleration position detection unit 45 is located in a position where, when the opening / closing body 20 is located in a range from the opening side deceleration position to the fully open position, the magnet portion provided on the opening / closing body 20 acts on the opening side deceleration position detection unit 45, causing the operating state of the opening side deceleration position detection unit 45 to be in the on state.

[0098] However, this is not limited to this, and for example, the opening side deceleration position detection unit 45 may be located in a position where the magnet portion provided on the opening / closing body 20 acts on the opening side deceleration position detection unit 45, causing the operating state of the opening side deceleration position detection unit 45 to be in the on state only when the opening / closing body 20 is located in the opening side deceleration position.

[0099] Further, the detection operation of the disengagement side deceleration position detection unit 45 is optional, but in this embodiment it operates as follows.

[0100] That is, when the opening-closing body 20 is located at the opening-side deceleration position, the magnet portion provided in the opening-closing body 20 acts on the opening-side deceleration position detection unit 45, causing the opening-side deceleration position detection unit 45 to turn on, causing the opening-side deceleration position detection unit 45 to output a signal indicating that the opening-side body 20 has reached the opening-side deceleration position (hereinafter referred to as the "opening-side deceleration position detection signal"). Note that as long as the opening-side deceleration position detection unit 45 maintains its on state, the opening-side deceleration position detection unit 45 continues to output the opening-side deceleration position detection signal.

[0101] On the other hand, when the opening / closing body 20 is not positioned in the opening side deceleration position (except in the range from the opening side deceleration position to the fully open position), the magnet portion provided on the opening / closing body 20 does not act on the opening side deceleration position detection unit 45, causing the operating state of the opening side deceleration position detection unit 45 to be in the off state, and therefore the opening side deceleration position detection unit 45 does not output an opening side deceleration position detection signal.

[0102] (Configuration - Opening and closing control system - First obstacle detection unit) The first obstacle detection unit 46 is a first obstacle detection means that detects an obstacle (not shown).

[0103] Here, the term "obstacle" refers to anything that becomes an obstacle that impedes the opening and closing movement of the opening and closing body 20, and includes, for example, a person, an animal, an object, etc.

[0104] This first obstacle detection unit 46 is configured using a non-contact obstacle detection sensor (for example, a photoelectric sensor), and specifically, as shown in Figure 1, is configured to include a light-transmitting unit 46a and a light-receiving unit 46b that receives the detection light transmitted from the light-transmitting unit 46a.

[0105] As shown in FIG. 1, the first obstacle detector 46 is provided below the opening 3 and in front of and / or behind the opening 3.

[0106] Furthermore, the method of installing the first obstacle detection unit 46 is arbitrary, but in the embodiment, the first obstacle detection unit 46 is installed so that the detection range of the first obstacle detection unit 46 includes only a portion of the area in which the opening / closing body 20 moves open and closed.

[0107] Specifically, as shown in FIG. 1, the first obstacle detection unit 46 is installed so that the light-transmitting unit 46a is located at or near the left end of the opening 3, and the light-receiving unit 46b is located at or near the right end of the opening 3.

[0108] The reason for installing the first obstacle detection unit 46 as described above is that in the embodiment, in addition to the first obstacle detection unit 46, a second obstacle detection unit 47 is provided, and therefore the second obstacle detection unit 47 can cover the detection range that the detection range of the first obstacle detection unit 46 cannot cover.

[0109] Furthermore, the detection operation of the first obstacle detection unit 46 is optional, but in this embodiment it operates as follows.

[0110] In other words, if the detection light sent from the light-transmitting unit 46a is blocked by an obstacle and the light-receiving unit 46b cannot receive the detection light, it is determined that an obstacle is present and a signal indicating that an obstacle has been detected (hereinafter referred to as the "first obstacle detection signal") is output.

[0111] On the other hand, if the light receiving section 46b can receive the detection light sent from the light sending section 46a, it is determined that no obstacle is present and the first obstacle detection signal is not output.

[0112] (Configuration - Opening and closing control system - Second obstacle detection unit) The second obstacle detection unit 47 is a second obstacle detection means that detects an obstacle. From the viewpoint of accurately detecting an obstacle, the second obstacle detection unit 47 is configured using a contact-type obstacle detection sensor, and more specifically, is configured with an overload detection sensor that detects whether the drive unit 30 is in an overload state.

[0113] As shown in FIG. 1, the second obstacle detector 47 is provided inside the interceptor 13 and near the drive unit 30.

[0114] Furthermore, the detection operation of the second obstacle detection unit 47 is optional, but in this embodiment it operates as follows.

[0115] That is, when the load on the drive unit 30 becomes equal to or greater than a threshold value due to an obstacle being caught by the opening / closing body 20, it is determined that an obstacle is present, and a signal indicating that an obstacle has been detected (hereinafter referred to as a "second obstacle detection signal") is output.

[0116] On the other hand, when the load amount on the drive unit 30 is less than the threshold value, it is determined that no obstacle is present, and the second obstacle detection signal is not output.

[0117] (Configuration - Switching control system - Switching output section) The open / close output unit 48 is an output means that outputs various information based on the control of the control unit 50. The open / close output unit 48 is configured using, for example, a known display means (a display as one example) or a known audio output means (a speaker as one example), and is provided in the vicinity of the opening 3 as shown in FIG.

[0118] (Configuration - Opening and closing control system - Control unit) The control unit 50 is a unit for controlling the opening and closing control system 40, and as shown in FIG. 3, is configured to include an input unit 51, an output unit 52, a power supply unit 53, a control unit 54, and a storage unit 55.

[0119] (Configuration - Opening and closing control system - Control unit - Input section) The input unit 51 is an input means that receives various signal inputs from the drive unit 30, the operation unit 41, the fully closed position detection unit 42, the fully open position detection unit 43, the closed side deceleration position detection unit 44, the open side deceleration position detection unit 45, the first obstacle detection unit 46, or the second obstacle detection unit 47, and is configured using, for example, a known input terminal, etc.

[0120] (Configuration - Opening and closing control system - Control unit - Output section) The output unit 52 is an output means that outputs various signals to the drive unit 30, the opening / closing output unit 48, or an external device (e.g., a management device, a terminal device, etc.) not shown, and is configured using, for example, known output terminals, etc.

[0121] (Configuration - Opening and closing control system - Control unit - Power supply unit) The power supply unit 53 is a power supply means that supplies power supplied from a commercial power source or a battery (e.g., a battery, etc.) not shown to each part of the control unit 50, and also supplies power via wiring 4 to the drive unit 30, operation unit 41, fully closed position detection unit 42, fully open position detection unit 43, closed side deceleration position detection unit 44, open side deceleration position detection unit 45, first obstacle detection unit 46, second obstacle detection unit 47, and / or opening / closing output unit 48.

[0122] (Configuration - Opening and closing control system - Control unit - Control section) The control unit 54 is a control means that controls each part of the control unit 50. Specifically, the control unit 54 is a computer that includes a CPU, various programs that are interpreted and executed on the CPU (including basic control programs such as an OS, and application programs that are started on the OS and realize specific functions), and an internal memory such as a RAM for storing the programs and various data.

[0123] As shown in FIG. 3, the control section 54 conceptually includes an opening / closing control section 54a.

[0124] Of these, the opening / closing control section 54a is an opening / closing control means that controls the opening / closing movement of the opening / closing body 20 based on the detection results of the opening-side detection section 40b and the closing-side detection section 40a.

[0125] The processing executed by the control unit 54 will be described in detail later.

[0126] (Configuration - Opening and closing control system - Control unit - Memory unit) The storage unit 55 is a storage means for storing programs and various data required for the operation of the control device, and is configured using a rewritable recording medium, and may be a non-volatile recording medium such as a flash memory.

[0127] (Opening and closing process) Next, the opening and closing process executed by the control section 54 of the control unit 50 of the opening and closing control system 40 will be described.

[0128] In the following description, steps will be abbreviated as "S" in the explanation of each process shown in FIGS.

[0129] The opening / closing process is a process for controlling the opening / closing movement of the opening / closing body 20.

[0130] The timing for executing this opening / closing process is arbitrary, but in the embodiment, it will be described that the process is started after the sliding door 1 is powered on.

[0131] (Opening and closing process - premise) Next, the premise of the opening and closing process in this embodiment is as follows.

[0132] That is, the description will be given assuming that the opening / closing body 20 is in a fully open state.

[0133] In addition, the sliding door 1 will be described assuming that the processing necessary to perform opening and closing processes (for example, setting processes to set the fully open position, fully closed position, closing side deceleration position, and opening side deceleration position) has already been performed.

[0134] (Opening and closing process - Opening and closing process details) Next, the opening and closing process will be described in detail.

[0135] When the opening / closing process is started, the opening / closing control section 54a of the control unit 50 determines whether or not a closing signal has been input from the operation section 41 via the input section 51 at SA1, as shown in FIG.

[0136] When it is determined that the input of the close signal has been received (SA1, Yes), the opening / closing control section 54a of the control unit 50 starts the close process (SA2) and then proceeds to SA1. Details of the process of the close process will be described later.

[0137] On the other hand, if it is determined that the input of the close signal has not been accepted (SA1, No), the opening / closing control section 54a of the control unit 50 proceeds to SA3.

[0138] In SA3, the opening / closing control section 54a of the control unit 50 determines whether or not an input of an opening signal from the operation section 41 via the input section 51 has been accepted.

[0139] When it is determined that the input of the opening signal has been received (SA3, Yes), the opening / closing control section 54a of the control unit 50 starts an opening process (SA4) and then proceeds to SA1. The details of the opening process will be described later.

[0140] On the other hand, if it is determined that the input of the open signal has not been accepted (SA3, No), the opening / closing control section 54a of the control unit 50 proceeds to SA1, and thereafter similarly repeats the processes from SA1 to SA4.

[0141] In the embodiment, although not shown in the flowcharts of FIGS. 4 to 6, the following processing is performed.

[0142] Specifically, when a stop signal is received from the operation unit 41 via the input unit 51 during the closing process of SA2 or the opening process of SA4, the opening / closing control unit 54a of the control unit 50 stops the closing or opening movement of the opening / closing body 20 (this may be omitted if the stop has already been made), and transitions to SA1 after completing the closing or opening process.

[0143] Furthermore, when an opening signal is received from the operation unit 41 via the input unit 51 during the closing process of SA2, the opening / closing control unit 54a of the control unit 50 stops the closing movement of the opening / closing body 20 (this may be omitted if the stopping has already been performed), and after completing the closing process, transitions to SA4.

[0144] Furthermore, if the opening / closing control unit 54a of the control unit 50 receives a closing signal input from the operation unit 41 via the input unit 51 during the opening process of SA4, it stops the opening movement of the opening / closing body 20 (this may be omitted if the stop has already been made), and transitions to SA2 after completing the opening process.

[0145] (Opening / closing process - Closing process) Next, the closing process will be described.

[0146] The closing process is a process for controlling the closing movement of the opening / closing body 20.

[0147] When the closing process is initiated, as shown in Figure 5, the opening / closing control unit 54a of the control unit 50 at SB1 performs control (hereinafter referred to as "closing control") to move the opening / closing body 20 to the closing position based on the closing signal received as input at SA1.

[0148] The control content of this closing control is arbitrary, but in the embodiment, the opening / closing control unit 54a of the control unit 50 simply outputs a control signal corresponding to the closing signal whose input is accepted at SA1 to the drive unit 30 via the output unit 52, and drives the drive unit 30 based on the control signal, thereby moving the opening / closing body 20 to the closing position.

[0149] In this case, in the embodiment, even if the acceptance of the input of the closing signal is stopped, the closing movement of the opening / closing body 20 is continued by continuing to output the control signal to drive the drive unit 30. In other words, the closing movement of the opening / closing body 20 is performed in accordance with the so-called "self-holding operation."

[0150] However, the present invention is not limited to this, and for example, when the reception of the input of the closing signal is stopped, the closing movement of the opening / closing body 20 may be stopped. In other words, the closing movement of the opening / closing body 20 may be performed in response to a so-called "push-off operation."

[0151] In SB2, the opening / closing control section 54a of the control unit 50 determines whether the first obstacle detection section 46 and / or the second obstacle detection section 47 has detected an obstacle.

[0152] The method for determining whether or not the above-mentioned obstacle has been detected is arbitrary, but in this embodiment, the determination is made based on whether or not input of the first obstacle detection signal and / or the second obstacle detection signal has been received from the first obstacle detection unit 46 and / or the second obstacle detection unit 47 via the input unit 51.

[0153] Here, if the input of the first obstacle detection signal and / or the second obstacle detection signal is accepted, it is determined that an obstacle has been detected, and if the input of the first obstacle detection signal and the second obstacle detection signal is not accepted, it is determined that an obstacle has not been detected.

[0154] Then, the opening / closing control unit 54a of the control unit 50 transitions to SB3 if it determines that the above-mentioned obstacle has been detected (SB2, Yes), and transitions to SB4 if it determines that the above-mentioned obstacle has not been detected (SB2, No).

[0155] In SB3, the opening / closing control section 54a of the control unit 50 performs the first avoidance control or the second avoidance control, and after the first avoidance control or the second avoidance control is performed, the closing process is terminated.

[0156] In the embodiment, when the input of the first obstacle detection signal and the second obstacle detection signal is accepted at SB2, the opening / closing control section 54a of the control unit 50 performs only the first avoidance control. However, this is not limiting, and for example, only the second avoidance control may be performed, or either the first avoidance control or the second avoidance control may be selected at random and performed.

[0157] Here, "first avoidance control" refers to control regarding the opening and closing movement of the opening / closing body 20 when an obstacle is detected by the first obstacle detection unit 46, and means control that at least avoids the obstacle from being pinched by the opening / closing body 20.

[0158] In addition, the "second avoidance control" refers to control relating to the opening and closing movement of the opening-closing body 20 when an obstacle is detected by the second obstacle detection unit 47, and means control that at least avoids the obstacle from being pinched by the opening-closing body 20.

[0159] In this embodiment, the phrase "an obstacle being caught by the opening / closing body 20" means that an obstacle is caught between the opening / closing body 20 and the closing-side door stop portion 16.

[0160] However, the present invention is not limited to this, and may mean that an obstacle is caught between the opening and closing bodies 20 when the sliding door 1 is a sliding door, for example.

[0161] Furthermore, each of these first avoidance control and second avoidance control is a concept that includes, for example, non-reverse opening control, first reverse opening control, and / or second reverse opening control, but in the embodiment, the first avoidance control will be described as performing second reverse opening control, and the second avoidance control will be described as performing non-reverse opening control.

[0162] Of these, the "non-reverse opening control" means a control that simply stops the closing movement of the opening / closing body 20.

[0163] The control content of this non-reverse opening control is arbitrary, but for example, the opening / closing control unit 54a of the control unit 50 outputs a control signal corresponding to a stop signal to the drive unit 30 via the output unit 52, thereby stopping the drive of the drive unit 30 based on the control signal, thereby stopping the closing movement of the opening / closing body 20.

[0164] In addition, "first reverse opening control" means a control in which, after stopping the closing movement of the opening / closing body 20, the opening / closing body 20 is moved to an opening position by a predetermined distance (e.g., approximately 5 cm to 10 cm) or a predetermined time (e.g., approximately 3 seconds to 6 seconds) and then stopped.

[0165] The control content of this first reverse opening control is arbitrary, but for example, first, the opening / closing control unit 54a of the control unit 50 outputs a control signal corresponding to a stop signal to the drive unit 30 via the output unit 52, thereby stopping the drive of the drive unit 30 based on the control signal, thereby stopping the closing movement of the opening / closing body 20. Next, by outputting a control signal corresponding to an opening signal to the drive unit 30 via the output unit 52 for a predetermined distance or a predetermined time, the drive unit 30 is driven based on the control signal, thereby moving the opening / closing body 20 to an opening position for a predetermined distance or a predetermined time. Thereafter, by outputting a control signal corresponding to a stop signal to the drive unit 30 via the output unit 52, the drive of the drive unit 30 is stopped based on the control signal, thereby stopping the opening movement.

[0166] Further, the "second reverse opening control" refers to a control in which, after the closing movement of the opening / closing body 20 is stopped, the opening movement of the opening / closing body 20 is continued until the opening / closing body 20 reaches the fully open position, and then the opening / closing body 20 is stopped.

[0167] The control content of this second reverse opening control is arbitrary, but for example, first, the opening / closing control unit 54a of the control unit 50 outputs a control signal corresponding to a stop signal to the drive unit 30 via the output unit 52, thereby stopping the driving of the drive unit 30 based on the control signal, thereby stopping the closing movement of the opening / closing body 20. Next, it outputs a control signal corresponding to an open signal to the drive unit 30 via the output unit 52, thereby driving the drive unit 30 based on the control signal, thereby moving the opening / closing body 20 to the open position. Thereafter, when the fully open position detection unit 43 detects that the opening / closing body 20 has reached the fully open position, it outputs a control signal corresponding to the stop signal to the drive unit 30 via the output unit 52, thereby stopping the driving of the drive unit 30 based on the control signal, thereby stopping the opening movement.

[0168] For example, when the first avoidance control or the second avoidance control is performed, the opening / closing control section 54a of the control unit 50 may display and / or output by voice information indicating that the first avoidance control or the second avoidance control is being performed by the opening / closing output section 48 via the output section 52 (the same applies to the avoidance control described below).

[0169] As described above, each of the first avoidance control and the second avoidance control includes non-reverse opening control, first reverse opening control, and / or second reverse opening control, so that the first avoidance control and the second avoidance control can be performed according to the usage situation, thereby improving the usability of the opening / closing control system 40.

[0170] In the embodiment, the first avoidance control and the second avoidance control are each described as controls to avoid an obstacle being pinched by the opening / closing body 20, but this is not limited to this, and for example, in addition to the above controls, they may also include controls to avoid collision or contact between the opening / closing body 20 and an obstacle (note that the same applies to the avoidance controls described below).

[0171] By processing SB1 to SB3 in this manner, when closing control is being performed, the first avoidance control or the second avoidance control can at least prevent an obstacle from being pinched by the opening / closing body 20, thereby increasing safety when using the sliding door 1.

[0172] In SB4, the opening / closing control section 54a of the control unit 50 determines whether the opening / closing body 20 has reached the closing side deceleration position.

[0173] The method for determining whether or not the closing side deceleration position has been reached is arbitrary, but in this embodiment, the determination is made based on whether or not an input of a closing side deceleration position detection signal has been received from the closing side deceleration position detection unit 44 via the input unit 51.

[0174] Here, if the input of the closing side deceleration position detection signal is accepted, it is determined that the closing side deceleration position has been reached, and if the input of the closing side deceleration position detection signal is not accepted, it is determined that the closing side deceleration position has not been reached.

[0175] Then, if the opening / closing control unit 54a of the control unit 50 determines that the closing side deceleration position has been reached (SB4, Yes), it proceeds to SB5, and if it determines that the closing side deceleration position has not been reached (SB4, No), it proceeds to SB2.

[0176] In SB5, the opening / closing control section 54a of the control unit 50 performs control to decelerate the speed of the closing movement of the opening / closing body 20 due to the closing control of SB1 (hereinafter referred to as "closing side deceleration control").

[0177] The control content of this closing side deceleration control is arbitrary, but in the embodiment, in addition to controlling the closing of SB1, the opening / closing control unit 54a of the control unit 50 outputs a signal (hereinafter referred to as a "deceleration operation signal") to the driving unit 30 via the output unit 52 to decelerate the rotational speed of the motor 34 of the driving unit 30, thereby slowing down the speed of the closing movement of the opening / closing body 20 below the speed during the closing control based on the deceleration operation signal.

[0178] In SB6, the opening / closing control section 54a of the control unit 50 determines whether or not an obstacle has been detected by the first obstacle detection section 46 and / or the second obstacle detection section 47, in substantially the same manner as in the process of SB2.

[0179] Then, if the opening / closing control unit 54a of the control unit 50 determines that the above-mentioned obstacle has been detected (SB6, Yes), it proceeds to SB7, and if it determines that the above-mentioned obstacle has not been detected (SB6, No), it proceeds to SB8.

[0180] In SB7, the opening / closing control section 54a of the control unit 50 performs the first avoidance control or the second avoidance control in substantially the same manner as in the process of SB3, and then ends the closing process.

[0181] By processing SB5 to SB7 in this manner, when closing side deceleration control is being performed, the first avoidance control or the second avoidance control can at least prevent obstacles from being pinched by the opening / closing body 20, thereby increasing safety when using the sliding door 1.

[0182] Furthermore, taking into consideration the processing of SB1 to SB7, when the opening / closing body 20 is moving to the closed position, the opening / closing control section 54a of the control unit 50 performs the second avoidance control if the fully closed position detection section 42 does not detect that the opening / closing body 20 has reached the fully closed position, but an obstacle is detected by the second obstacle detection section 47.Therefore, when the opening / closing body 20 has not reached the fully closed position, the second avoidance control can at least prevent the opening / closing body 20 from pinching an obstacle, thereby further improving safety when using the sliding door 1.

[0183] In SB8, the opening / closing control section 54a of the control unit 50 determines whether the opening / closing body 20 has reached the fully closed position.

[0184] The method for determining whether or not the fully closed position has been reached is arbitrary, but in this embodiment, the determination is made based on whether or not input of a fully closed position detection signal has been received from the fully closed position detection unit 42 via the input unit 51.

[0185] Here, if the input of the fully closed position detection signal is accepted, it is determined that the fully closed position has been reached, and if the input of the fully closed position detection signal is not accepted, it is determined that the fully closed position has not been reached.

[0186] Then, if the opening / closing control section 54a of the control unit 50 determines that the fully closed position has been reached (SB8, Yes), it proceeds to SB9, and if it determines that the fully closed position has not been reached (SB8, No), it proceeds to SB6.

[0187] In SB9, the opening / closing control unit 54a of the control unit 50 performs control (hereinafter referred to as "pressing control") to continue the closing movement of the opening / closing body 20 for a predetermined time (e.g., approximately 2 to 10 seconds) or a predetermined distance (e.g., approximately 1 mm to 5 cm) and then stop it.

[0188] The control content of this pressing control is arbitrary, but in the embodiment, the opening / closing control unit 54a of the control unit 50 continues the closing movement of the opening / closing body 20 by the closing side deceleration control of SB5 for a predetermined time or a predetermined distance even after processing SB8, and then outputs a control signal corresponding to a stop signal to the drive unit 30 via the output unit 52, thereby stopping the drive of the drive unit 30 based on the control signal and thereby stopping the closing movement.

[0189] However, without being limited thereto, for example, the opening / closing control unit 54a of the control unit 50 outputs a control signal corresponding to a stop signal to the drive unit 30 via the output unit 52, thereby stopping the drive of the drive unit 30 based on the control signal, thereby stopping the closing movement of the opening / closing body 20 through the closing side deceleration control of SB5. Next, by outputting a control signal corresponding to the closing signal to the drive unit 30 via the output unit 52 for a predetermined distance or a predetermined time, the drive unit 30 is driven based on the control signal, thereby moving the opening / closing body 20 in the closing direction. Thereafter, by outputting a control signal corresponding to the stop signal to the drive unit 30 via the output unit 52, the drive of the drive unit 30 is stopped based on the control signal, thereby stopping the above-mentioned closing movement.

[0190] In SB10, the opening / closing control section 54a of the control unit 50 determines whether or not an obstacle has been detected by the first obstacle detection section 46, in substantially the same manner as in the processing in SB2.

[0191] Then, the opening / closing control unit 54a of the control unit 50 transitions to SB11 if it determines that the above-mentioned obstacle has been detected (SB10, Yes), and transitions to SB12 if it determines that the above-mentioned obstacle has not been detected (SB10, No).

[0192] In SB11, the opening / closing control section 54a of the control unit 50 performs the first avoidance control in substantially the same manner as in the process in SB3, and then ends the closing process.

[0193] In addition, in SB11, the opening / closing control unit 54a of the control unit 50 will not perform the second avoidance control regardless of the detection result of the second obstacle detection unit 47 (in other words, when the opening / closing body 20 is moving to the closed position and the fully closed position detection unit 42 detects that the opening / closing body 20 has reached the fully closed position, the second avoidance control will not be performed regardless of the detection result of the second obstacle detection unit 47).

[0194] The reason why the second avoidance control is not performed in the processing of SB11 is as follows.

[0195] That is, if the opening / closing body 20 comes into contact with the closing-side door stop portion 16 during the pressing control of SB9, and the second obstacle detection unit 47 erroneously detects the presence of an obstacle, the second avoidance control is performed, which causes a problem that it becomes difficult to maintain the pressing control. Therefore, in order to avoid such a problem, the second avoidance control is not performed in the processing of SB11.

[0196] By performing the processes from SB9 to SB11 in this manner, when the pressing control is being performed, the first avoidance control can be used to prevent an obstacle from being caught by the opening / closing body 20, thereby making it possible to improve safety when using the sliding door 1.

[0197] Furthermore, when the opening / closing body 20 has reached the fully closed position, it is possible to prevent the pressing control from being hindered by the second avoidance control, and the usability of the opening / closing control system 40 can be improved.

[0198] In SB12, the opening / closing control section 54a of the control unit 50 determines whether or not the timing for ending the pressing control of SB9 (hereinafter referred to as "ending timing") has arrived.

[0199] The method for determining whether this end timing has arrived is arbitrary, but in the embodiment, the determination is made based on whether the drive of the drive unit 30 has stopped after the closing movement of the opening / closing body 20 has been performed for a predetermined time or distance by the pressing control of SB9.

[0200] Here, if the driving of the drive unit 30 has stopped, it is determined that the end timing has arrived, and if the driving of the drive unit 30 has not stopped, it is determined that the end timing has not arrived.

[0201] Then, the opening / closing control unit 54a of the control unit 50 terminates the closing process if it determines that the end timing has arrived (SB12, Yes), and transitions to SB10 if it determines that the end timing has not arrived (SB12, No).

[0202] By such a closing process, when the opening / closing body 20 is moved to close, safety during use of the sliding door 1 and usability of the sliding door 1 can be ensured, and usability of the opening / closing control system 40 can be improved.

[0203] (Opening and closing process - Opening process) Next, the release process will be described.

[0204] The opening process is a process for controlling the opening movement of the opening / closing body 20.

[0205] When the opening process is initiated, as shown in Figure 6, the opening / closing control unit 54a of the control unit 50 at SC1 performs control (hereinafter referred to as "opening control") to move the opening / closing body 20 to open based on the opening signal input accepted at SA3.

[0206] The control content of this opening control is arbitrary, but in the embodiment, the opening / closing control unit 54a of the control unit 50 simply outputs a control signal corresponding to the opening signal received as input at SA3 to the drive unit 30 via the output unit 52, and drives the drive unit 30 based on the control signal, thereby moving the opening / closing body 20 to the open position.

[0207] In this case, in the embodiment, the opening / closing body 20 is moved to open in response to the "self-holding operation" in a manner similar to the closing control of SB1. However, this is not limiting, and the opening / closing body 20 may be moved to close in response to, for example, the "push-off operation."

[0208] At SC2, the opening / closing control section 54a of the control unit 50 determines whether or not an obstacle has been detected by the second obstacle detection section 47, regardless of the detection result of the first obstacle detection section 46.

[0209] Then, if the opening / closing control unit 54a of the control unit 50 determines that the above-mentioned obstacle has been detected (SC2, Yes), it proceeds to SC3, and if it determines that the above-mentioned obstacle has not been detected (SC2, No), it proceeds to SC4.

[0210] At SC3, the opening / closing control section 54a of the control unit 50 performs avoidance control, and then ends the opening process.

[0211] Here, the reason why avoidance control is not performed based on the detection result of the first obstacle detection unit 46 in the processes of SC2 and SC3 is as follows.

[0212] That is, since the first obstacle detection unit 46 is a non-contact type obstacle detection sensor, it always detects an obstacle when a passing object (not shown, for example, a person, an animal, or an object (such as a vehicle, for example)) passes through the opening 3. On the other hand, since the second obstacle detection unit 47 is a contact type obstacle detection sensor, it does not always detect an obstacle when passing through the opening 3, and also detects a malfunction of the drive unit 30 or a collision between the opening / closing body 20 and an object as an obstacle. Considering these points, from the viewpoint of improving safety when using the sliding door 1, it is preferable to perform avoidance control based only on the detection result of the second obstacle detection unit 47 when opening side deceleration control is not being performed, and therefore, in the processing of SC3, avoidance control is not performed based on the detection result of the first obstacle detection unit 46.

[0213] In addition, "avoidance control" refers to control regarding the opening and closing movement of the opening / closing body 20 when an obstacle is detected by the first obstacle detection unit 46 and / or the second obstacle detection unit 47, and means control that at least avoids the obstacle from being pinched by the opening / closing body 20.

[0214] In the embodiment, "an obstacle being pinched by the opening / closing body 20" means that an obstacle is pinched between the opening / closing body 20 and the open side door stop portion 17 (the same applies, for example, to the case where the sliding door 1 is a sliding door).

[0215] Furthermore, this avoidance control is a concept that includes, for example, non-reverse closing control and / or reversal closing control, but in the embodiment, the description will be given assuming that non-reversal closing control is performed.

[0216] Of these, the "non-reverse closing control" means control that simply stops the opening movement of the opening / closing body 20.

[0217] The control content of this non-reversal closing control is arbitrary, but for example, the opening / closing control unit 54a of the control unit 50 outputs a control signal corresponding to a stop signal to the drive unit 30 via the output unit 52, thereby stopping the drive of the drive unit 30 based on the control signal, thereby stopping the closing movement of the opening / closing body 20.

[0218] In addition, "reverse closing control" means control in which, after stopping the closing movement of the opening / closing body 20, the opening / closing body 20 moves in the closing direction for a predetermined distance (e.g., approximately 5 cm to 10 cm) or for a predetermined time (e.g., approximately 3 to 6 seconds) and then stops.

[0219] The control content of this reverse closing control is arbitrary, but for example, first, the opening / closing control unit 54a of the control unit 50 outputs a control signal corresponding to a stop signal to the drive unit 30 via the output unit 52, thereby stopping the drive of the drive unit 30 based on the control signal, thereby stopping the opening movement of the opening / closing body 20. Next, the control signal corresponding to a closing signal is output to the drive unit 30 via the output unit 52 for a predetermined distance or a predetermined time, thereby driving the drive unit 30 based on the control signal, thereby moving the opening / closing body 20 to close for a predetermined distance or a predetermined time. Thereafter, the control signal corresponding to the stop signal is output to the drive unit 30 via the output unit 52, thereby stopping the drive of the drive unit 30 based on the control signal, thereby stopping the closing movement.

[0220] As described above, the avoidance control includes non-reverse closing control and / or reverse closing control, so that avoidance control can be performed according to the usage situation, and the usability of the opening and closing control system 40 can be improved.

[0221] Furthermore, by processing SC1 to SC3 in this manner, when opening control is being performed, avoidance control can be used to prevent the opening / closing body 20 from causing harm to passing objects (for example, a collision between the opening / closing body 20 and a passing object), thereby increasing safety when using the sliding door 1.

[0222] In SC4, the opening / closing control section 54a of the control unit 50 determines whether the opening / closing body 20 has reached the opening-side deceleration position.

[0223] The method for determining whether or not the above-mentioned opening side deceleration position has been reached is arbitrary, but in this embodiment, the determination is made based on whether or not an input of an opening side deceleration position detection signal has been received from the opening side deceleration position detection unit 45 via the input unit 51.

[0224] Here, if the input of the opening side deceleration position detection signal is accepted, it is determined that the opening side deceleration position has been reached, and if the input of the opening side deceleration position detection signal is not accepted, it is determined that the opening side deceleration position has not been reached.

[0225] Then, if the opening / closing control unit 54a of the control unit 50 determines that the above-mentioned opening side deceleration position has been reached (SC4, Yes), it proceeds to SC5, and if it determines that the above-mentioned opening side deceleration position has not been reached (SC4, No), it proceeds to SC2.

[0226] In SC5, the opening / closing control section 54a of the control unit 50 performs control to decelerate the speed of the opening movement of the opening / closing body 20 due to the opening control in SC1 (hereinafter referred to as "opening side deceleration control").

[0227] The control content of this opening side deceleration control is arbitrary, but in the embodiment, the opening / closing control unit 54a of the control unit 50, in addition to controlling the opening of SC1, outputs a deceleration operation signal to the drive unit 30 via the output unit 52, thereby slowing down the opening movement speed of the opening / closing body 20 below the speed at which it moves during the opening control based on the deceleration operation signal.

[0228] In SC6, the opening / closing control section 54a of the control unit 50 determines whether or not an obstacle has been detected by the first obstacle detection section 46 and / or the second obstacle detection section 47, in substantially the same manner as in the process of SB2.

[0229] Then, if the opening / closing control unit 54a of the control unit 50 determines that the above-mentioned obstacle has been detected (SC6, Yes), it proceeds to SC7, and if it determines that the above-mentioned obstacle has not been detected (SC6, No), it proceeds to SC8.

[0230] At SC7, the opening / closing control section 54a of the control unit 50 performs avoidance control, and then ends the opening process.

[0231] This avoidance control is a concept that includes, for example, non-reverse closing control and / or reverse closing control, but in the embodiment, the description will be given assuming that reverse closing control is performed.

[0232] Furthermore, by processing SC5 to SC7 in this manner, when opening side deceleration control is being performed, the avoidance control can prevent harm to passing objects by the opening / closing body 20 (for example, the passing object being pinched by the opening / closing body 20, or a collision between the opening / closing body 20 and the passing object, etc.), thereby making it possible to increase safety when using the sliding door 1.

[0233] In SC8, the opening / closing control section 54a of the control unit 50 determines whether the opening / closing body 20 has reached the fully open position.

[0234] The method for determining whether or not the fully open position has been reached is arbitrary, but in this embodiment, the determination is made based on whether or not a fully open position detection signal has been received from the fully open position detection unit 43 via the input unit 51.

[0235] Here, if the input of the fully open position detection signal is accepted, it is determined that the fully open position has been reached, and if the input of the fully open position detection signal is not accepted, it is determined that the fully open position has not been reached.

[0236] Then, if the opening / closing control unit 54a of the control unit 50 determines that the fully open position has been reached (SC8, Yes), it proceeds to SC9, and if it determines that the fully open position has not been reached (SC8, No), it proceeds to SC6.

[0237] In SC9, the opening / closing control section 54a of the control unit 50 performs control to stop the opening movement of the opening / closing body 20 (hereinafter referred to as "opening side stop control"), and then ends the opening process.

[0238] The control content of this opening side stop control is arbitrary, but in the embodiment, the opening / closing control unit 54a of the control unit 50 outputs a control signal corresponding to the stop signal to the drive unit 30 via the output unit 52, thereby stopping the drive of the drive unit 30 based on the control signal, thereby stopping the closing movement of the opening / closing body 20 due to the opening side deceleration control of SC5.

[0239] By such an opening process, when the opening / closing body 20 is moved to open, safety during use of the sliding door 1 and usability of the sliding door 1 can be ensured, and usability of the opening / closing control system 40 can be improved.

[0240] (Processing - Abnormal Processing) Next, abnormality processing will be described.

[0241] Abnormality processing is a process for controlling the sliding door 1 in response to an abnormality that occurs in the fully closed position detection unit 42, the closed side deceleration position detection unit 44, the fully open position detection unit 43, or / and the open side deceleration position detection unit 45.

[0242] Here, "abnormality" refers to, for example, wear of the upper guide rail, the lower guide rail 15a, and / or the guided member as the sliding door 1 is used, which causes the gap between the opening / closing body 20 and the fully closed position detection unit 42, the closing side deceleration position detection unit 44, the fully open position detection unit 43, or the opening side deceleration position detection unit 45 to widen, making it difficult to switch the operating state of the fully closed position detection unit 42, the closing side deceleration position detection unit 44, the fully open position detection unit 43, or / and the opening side deceleration position detection unit 45 to the on or off state, or / and failure of the fully closed position detection unit 42, the closing side deceleration position detection unit 44, the fully open position detection unit 43, or / and the opening side deceleration position detection unit 45, making it impossible to output various detection signals and / or stop the output at the appropriate time.

[0243] The timing for executing this abnormality processing is arbitrary, but in the embodiment, it is described as being started after the power supply of the sliding door 1 is turned on, and being executed in parallel with the opening and closing processing.

[0244] When the abnormality processing is started, as shown in FIG. 7, the switching control section 54a of the control unit 50 determines whether or not the first abnormality occurrence timing has arrived at SD1.

[0245] Here, the "first abnormality occurrence timing" refers to the timing at which an abnormality that would not normally occur during the opening / closing process occurs in the closing side deceleration position detection unit 44 and / or the opening side deceleration position detection unit 45. In the embodiment, this first abnormality occurrence timing is described as the timing at which the opening side deceleration position detection unit 45 detects that the opening / closing body 20 has reached the opening side deceleration position, and the closing side deceleration position detection unit 44 detects that the opening / closing body 20 has reached the closing side deceleration position.

[0246] The reason why the first abnormality occurrence timing according to the embodiment is set to the above timing is as follows.

[0247] 1, when the opening-side deceleration position detection unit 45 detects that the opening-side body 20 has reached the opening-side deceleration position, the closing-side deceleration position detection unit 44 does not detect that the opening-side body 20 has reached the closing-side deceleration position. Also, when the closing-side deceleration position detection unit 44 detects that the opening-side body 20 has reached the closing-side deceleration position, the opening-side deceleration position detection unit 45 does not detect that the opening-side body 20 has reached the opening-side deceleration position. In light of these facts, in the opening and closing process, it is normally impossible for the opening-side deceleration position detection unit 45 to detect that the opening-side body 20 has reached the opening-side deceleration position and the closing-side deceleration position detection unit 44 to detect that the opening-side body 20 has reached the closing-side deceleration position, so the first abnormality occurrence timing according to the embodiment is set to the timing described above.

[0248] Furthermore, the method for determining whether the timing for the first abnormality to occur has arrived is arbitrary, but in the embodiment, the determination is made based on whether input of the opening side deceleration position detection signal and the closing side deceleration position detection signal is received via the input unit 51 from the opening side deceleration position detection unit 45 and the closing side deceleration position detection unit 44 during processing of SD1.

[0249] Here, if the input of the opening side deceleration position detection signal and the closing side deceleration position detection signal is accepted, it is determined that the timing for the first abnormality to occur has arrived, and if the input of the opening side deceleration position detection signal or the closing side deceleration position detection signal is not accepted, it is determined that the timing for the first abnormality to occur has not arrived.

[0250] Then, the opening / closing control unit 54a of the control unit 50 transitions to SD2 if it determines that the first abnormality occurrence timing has arrived (SD1, Yes), and transitions to SD5 if it determines that the first abnormality occurrence timing has not arrived (SD1, No).

[0251] Returning to Figure 7, at SD2, the opening / closing control unit 54a of the control unit 50 determines that an abnormality has occurred in the opening side deceleration position detection unit 45 and / or the closing side deceleration position detection unit 44, and executes the first abnormality treatment control.

[0252] In this embodiment, the opening / closing control section 54a of the control unit 50 continues to execute the first abnormality treatment control until a first recovery timing, which will be described later, arrives.

[0253] Here, "first abnormality treatment control" means control related to treatment for the abnormality specified in SD2 (abnormality treatment control).

[0254] This first abnormality treatment control is a concept that includes, for example, first abnormality restriction control, second abnormality restriction control, third abnormality restriction control, abnormal opening control, abnormal closing control, abnormal stop control, and / or abnormal output control, but in the embodiment, it will be described as including first abnormality restriction control, second abnormality restriction control, and abnormal output control.

[0255] Of these, the "first abnormality restriction control" refers to an abnormality treatment control that is performed when the opening / closing body 20 is moving in the open position, and after moving the opening / closing body 20 to the fully open position, restricts the opening / closing movement of the opening / closing body 20 until the first return timing described below arrives.

[0256] The control content of this first abnormality limiting control is arbitrary, but for example, first, the opening / closing control unit 54a of the control unit 50 continues the opening movement of the opening / closing body 20 by the opening / closing process until the fully open position detection unit 43 detects that the opening / closing body 20 has reached the fully open position. Next, when the fully open position detection unit 43 detects that the opening / closing body 20 has reached the fully open position, the opening / closing control unit 54a outputs a control signal corresponding to a stop signal to the drive unit 30 via the output unit 52, thereby stopping the drive of the drive unit 30 and thereby stopping the opening movement of the opening / closing body 20. Thereafter, even if an open signal or a close signal is received from the operation unit 41 via the input unit 51 until a first return timing described below arrives, the opening / closing process does not perform the opening / closing movement of the opening / closing body 20 based on the open signal or the close signal.

[0257] In addition, "second abnormality restriction control" refers to an abnormality treatment control that is performed when the opening / closing body 20 is moving in the closed position, and after moving the opening / closing body 20 in the closed position, restricts the opening / closing movement of the opening / closing body 20 until the first return timing described below arrives.

[0258] The control content of this second abnormality limiting control is arbitrary, but for example, first, the opening / closing control unit 54a of the control unit 50 continues the closing movement of the opening / closing body 20 by the opening / closing process until the fully closed position detection unit 42 detects that the opening / closing body 20 has reached the fully closed position. Next, when the fully closed position detection unit 42 detects that the opening / closing body 20 has reached the fully closed position, the opening / closing control unit 54a outputs a control signal corresponding to a stop signal to the drive unit 30 via the output unit 52, thereby stopping the drive of the drive unit 30 and thereby stopping the closing movement of the opening / closing body 20. Thereafter, until the first return timing described below arrives, in the opening / closing process, even if an open signal or a close signal is input from the operation unit 41 via the input unit 51, the opening / closing body 20 is not opened or closed based on the open signal or the close signal.

[0259] Furthermore, the "third abnormality restriction control" refers to an abnormality treatment control that is performed when the opening / closing body 20 is moving in an opening / closing direction and / or when the opening / closing movement of the opening / closing body 20 is stopped, and that restricts the opening / closing movement of the opening / closing body 20 after stopping the opening / closing movement of the opening / closing body 20 until the first return timing described below arrives (note that when the opening / closing movement of the opening / closing body 20 is stopped, stopping the opening / closing movement of the opening / closing body 20 is omitted).

[0260] The control content of this third abnormality limiting control is arbitrary, but for example, first, the opening / closing control section 54a of the control unit 50 outputs a control signal corresponding to a stop signal to the drive section 30 via the output section 52, thereby stopping the drive of the drive section 30 and thereby stopping the opening / closing movement of the opening / closing body 20. After that, until the arrival of the first return timing described below, in the opening / closing process, even if an open signal or a close signal is received from the operation section 41 via the input section 51, the opening / closing body 20 will not be opened or closed based on the open signal or the close signal.

[0261] In addition, "abnormal opening control" refers to the abnormality treatment control performed when the opening / closing body 20 is moving in the opening direction, which slows down the speed of the opening movement of the opening / closing body 20 until the first return timing described below arrives.

[0262] The control content of this abnormal opening control is arbitrary, but for example, when the opening movement of the opening / closing body 20 is performed by the opening / closing process until the first return timing described below arrives, the opening / closing control unit 54a of the control unit 50, in addition to controlling the opening movement of the opening / closing process, outputs a signal (hereinafter referred to as the ``abnormal deceleration operation signal'') to the drive unit 30 via the output unit 52 to decelerate the rotational speed of the motor 34 of the drive unit 30, thereby slowing the speed below the opening movement speed of the opening / closing process based on the abnormal deceleration operation signal.

[0263] In addition, in the opening / closing process after abnormal opening control has been performed, if an input of an opening signal, a closing signal, or a stop signal is received from the operating unit 41 via the input unit 51, even before the first return timing described below arrives, it is possible to perform opening / closing movement of the opening / closing body 20 based on the opening signal, the closing signal, or the stop signal (note that the same applies to the opening / closing process after abnormal closing control (or abnormal stop control) has been performed).

[0264] Furthermore, the method for setting the speed of the opening movement (or closing movement) of the opening / closing process based on the abnormal deceleration operation signal is arbitrary, but for example, it may be set to the same speed as the opening movement (or closing movement) of the opening / closing process based on the deceleration operation signal, or it may be set to be slower (or faster) than the speed of the opening movement (or closing movement) of the opening / closing process based on the deceleration operation signal.

[0265] In addition, "abnormal closing control" refers to the abnormality treatment control performed when the opening / closing body 20 is moving in the closing direction, which slows down the speed of the closing movement of the opening / closing body 20 until the first return timing described below arrives.

[0266] The control content of this abnormal closing control is arbitrary, but for example, when the closing movement of the opening / closing body 20 is performed by the opening / closing process until the first return timing described below arrives, the opening / closing control unit 54a of the control unit 50, in addition to controlling the closing movement of the opening / closing process, outputs an abnormal deceleration operation signal to the drive unit 30 via the output unit 52, thereby slowing down the speed of the closing movement of the opening / closing process based on the abnormal deceleration operation signal.

[0267] Furthermore, the term "abnormal stop control" refers to control that simply stops the opening / closing movement of the opening / closing body 20, among the abnormality treatment controls that are performed when the opening / closing body 20 is moving open or closed.

[0268] The control content of this abnormal stop control is arbitrary, but for example, the opening / closing control unit 54a of the control unit 50 outputs a control signal corresponding to a stop signal to the drive unit 30 via the output unit 52, thereby stopping the drive of the drive unit 30 and thereby stopping the opening / closing movement of the opening / closing body 20.

[0269] In addition, "abnormality output control" means the control of outputting notification information indicating that the timing for the first abnormality occurrence has arrived, among the abnormality treatment controls performed when the opening / closing body 20 is moving open or closed and / or when the opening / closing movement of the opening / closing body 20 has stopped.

[0270] The control content of this abnormal output control is arbitrary, but for example, the opening / closing control unit 54a of the control unit 50 displays and / or outputs alarm information via the output unit 52 by the opening / closing output unit 48 for a predetermined period (for example, 1 to 10 minutes, or until the first recovery timing arrives), and / or transmits the alarm information to an external device via the output unit 52.

[0271] By performing such processing of SD1 and SD2, the first abnormality treatment control can be performed when an abnormality occurs in the opening side deceleration position detection unit 45 and / or the closing side deceleration position detection unit 44. Therefore, it is possible to quickly take measures against the abnormality, and the safety when using the sliding door 1 can be improved.

[0272] Furthermore, since the first abnormality treatment control includes the first abnormality restriction control and the second abnormality restriction control, if an abnormality occurs in the opening side deceleration position detection unit 45 and / or the closing side deceleration position detection unit 44 during the opening movement of the opening / closing body 20 or during the closing movement of the opening / closing body 20, the first abnormality restriction control or the second abnormality restriction control can be performed, thereby preventing the opening / closing body 20 from moving in an unusual opening or closing direction until the first return timing arrives.

[0273] In addition, "an opening / closing movement of the opening / closing body 20 that is different from normal" means, for example, that the speed of the opening movement of the opening / closing body 20 is slowed down based on a deceleration operation signal from the start of the opening movement of the opening / closing body 20, and when the opening side deceleration position detection unit 45 detects that the opening / closing body 20 has reached the opening side deceleration position, the opening movement is performed not based on a deceleration operation signal (i.e., by performing an opening movement that increases in speed), causing the opening / closing body 20 to collide forcefully with the opening side door stop portion 17 at the fully open position, and / or that the speed of the closing movement of the opening / closing body 20 is slowed down based on a deceleration operation signal from the start of the closing movement of the opening / closing body 20, and when the closing side deceleration position detection unit 44 detects that the opening / closing body 20 has reached the closing side deceleration position, the closing movement is performed not based on a deceleration operation signal (i.e., by performing a closing movement that increases in speed), causing the opening / closing body 20 to collide forcefully with the closing side door stop portion 16 at the fully closed position.

[0274] In SD3, the opening / closing control section 54a of the control unit 50 determines whether the first return timing has arrived.

[0275] Here, the "first return timing" means the timing (return timing) at which the state specified in SD2 returns to the state before the occurrence of the abnormality.

[0276] In the embodiment, this first return timing is described as the timing when repair work is first performed to repair the opening side deceleration position detection unit 45 and / or the closing side deceleration position detection unit 44, then the power to the sliding door 1 is turned back on, and then operation confirmation work is performed to check the operation of the opening side deceleration position detection unit 45 and / or the closing side deceleration position detection unit 44, and then the input of a return operation (hereinafter referred to as the "first return operation") is received via the operation unit 41.

[0277] However, the timing is not limited to this, and may be, for example, the timing when the input of the first reset operation is received via the operation unit 41 after the power to the sliding door 1 is turned back on and the operation check work is performed.

[0278] The method for determining whether this first return timing has arrived is arbitrary, but in this embodiment, the determination is made based on whether the input of the first return operation has been accepted via the operating unit 41 since the power to the sliding door 1 was turned back on.

[0279] Here, if the input of the first reset operation is accepted after the power supply to the sliding door 1 is turned back on, it is determined that the first reset timing has arrived, and if the input of the first reset operation is not accepted after the power supply to the sliding door 1 is turned back on, it is determined that the first reset timing has not arrived.

[0280] Then, the opening / closing control unit 54a of the control unit 50 waits until it is determined that the first return timing has arrived (SD3, No), and if it is determined that the first return timing has arrived (SD3, Yes), it proceeds to SD4.

[0281] In SD4, the switching control section 54a of the control unit 50 stops the execution of the first abnormality treatment control, and then shifts to SD1.

[0282] Specifically, the opening / closing control unit 54a of the control unit 50 releases the restriction on the opening / closing movement of the opening / closing body 20 during the opening / closing process by the first abnormality restriction control or the second abnormality restriction control, and transitions to processing SA1 during the opening / closing process, thereby enabling the opening / closing movement of the opening / closing body 20 to be performed based on the opening signal or the closing signal when an input of an opening signal or a closing signal is received from the operation unit 41 via the input unit 51 during the opening / closing process.

[0283] By performing the processes SD3 and SD4 in this way, the opening and closing movement of the opening and closing body 20 can be performed safely as usual after the first return timing arrives, and the usability of the sliding door 1 can be ensured.

[0284] In SD5, the switching control section 54a of the control unit 50 determines whether the second abnormality occurrence timing has arrived.

[0285] Here, the "second abnormality occurrence timing" refers to the timing at which an abnormality that would not normally occur during the opening and closing process occurs in the fully closed position detection unit 42 and / or the closing side deceleration position detection unit 44. In the embodiment, this second abnormality occurrence timing is described as the timing at which the fully closed position detection unit 42 detects that the opening and closing body 20 has reached the fully closed position, but the closing side deceleration position detection unit 44 does not detect that the opening and closing body 20 has reached the closing side deceleration position.

[0286] The reason why the second abnormality occurrence timing according to the embodiment is set to the above timing is as follows.

[0287] That is, as described above, when the opening-closing body 20 is located in the range from the closing side deceleration position to the fully closed position, the operating state of the closing side deceleration position detection unit 44 is turned on, so when the opening-closing body 20 is located at the fully closed position, the fully closed position detection unit 42 detects that the opening-closing body 20 has reached the fully closed position, and the closing side deceleration position detection unit 44 detects that the opening-closing body 20 has reached the closing side deceleration position. From this, in the opening and closing process, it is normally impossible for the fully closed position detection unit 42 to detect that the opening-closing body 20 has reached the fully closed position, but the closing side deceleration position detection unit 44 does not detect that the opening-closing body 20 has reached the closing side deceleration position, so the second abnormality occurrence timing according to the embodiment is set to the timing described above.

[0288] Furthermore, the method for determining whether the timing for the second abnormality to occur has arrived is arbitrary, but in the embodiment, when processing SD5, the determination is made based on whether input of a fully closed position detection signal is received from the fully closed position detection unit 42 via the input unit 51, but input of a closed side deceleration position detection signal is not received from the closed side deceleration position detection unit 44 via the input unit 51.

[0289] Here, if the input of the fully closed position detection signal is accepted but the input of the closing side deceleration position detection signal is not accepted, it is determined that the timing for the second abnormality to occur has arrived, and if the input of the fully closed position detection signal is not accepted or the input of the closing side deceleration position detection signal is accepted, it is determined that the timing for the second abnormality to occur has not arrived.

[0290] Then, if the opening / closing control unit 54a of the control unit 50 determines that the second abnormality occurrence timing has arrived (SD5, Yes), it proceeds to SD6, and if it determines that the second abnormality occurrence timing has not arrived (SD5, No), it proceeds to SD9.

[0291] In SD6, the opening / closing control section 54a of the control unit 50 determines that an abnormality has occurred in the fully closed position detection section 42 and / or the closed side deceleration position detection section 44, and executes second abnormality treatment control.

[0292] In this embodiment, the opening / closing control section 54a of the control unit 50 continues to execute the second abnormality treatment control until a second recovery timing, which will be described later, arrives.

[0293] Here, "second abnormality treatment control" means control related to treatment for the abnormality specified in SD6 (abnormality treatment control).

[0294] This second abnormality treatment control is a concept that includes, for example, first abnormality restriction control, second abnormality restriction control, third abnormality restriction control, abnormal opening control, abnormal closing control, abnormal stop control, and / or abnormal output control, but in the embodiment, it will be described as including third abnormality restriction control and abnormal output control.

[0295] For example, when the first abnormality limiting control, the second abnormality limiting control, or the third abnormality limiting control is performed, the opening / closing body 20 is not opened or closed based on the open signal or the close signal until the second return timing described below arrives, even if the opening or closing signal is received from the operation unit 41 via the input unit 51. Furthermore, when the abnormality output control is performed, notification information indicating that the second abnormality occurrence timing has arrived is output.

[0296] By performing the processes of SD5 and SD6, the second abnormality treatment control can be performed when an abnormality occurs in the fully closed position detection unit 42 and / or the closing side deceleration position detection unit 44. Therefore, it is possible to quickly take measures against the abnormality identified in SD6, and the safety of the sliding door 1 when in use can be improved.

[0297] In SD7, the opening / closing control section 54a of the control unit 50 determines whether the second return timing has arrived.

[0298] Here, the "second return timing" refers to the timing (return timing) at which the state specified in SD6 returns to the state before the occurrence of the abnormality.

[0299] In the embodiment, this second return timing is described as the timing when repair work is first performed to repair the fully closed position detection unit 42 and / or the closing side deceleration position detection unit 44, then the power to the sliding door 1 is turned back on, and then operation confirmation work is performed to check the operation of the fully closed position detection unit 42 and / or the closing side deceleration position detection unit 44, and then the input of a return operation (hereinafter referred to as the "second return operation") is received via the operation unit 41.

[0300] However, the timing is not limited to this, and may be, for example, the timing when the input of the second reset operation is received via the operation unit 41 after the power to the sliding door 1 is turned back on and the operation check work is performed.

[0301] The method for determining whether this second return timing has arrived is arbitrary, but in this embodiment, the determination is made based on whether the input of the second return operation has been accepted via the operating unit 41 since the power to the sliding door 1 was turned back on.

[0302] Here, if the input of the second reset operation is accepted after the power supply to the sliding door 1 is turned back on, it is determined that the second reset timing has arrived, and if the input of the second reset operation is not accepted after the power supply to the sliding door 1 is turned back on, it is determined that the second reset timing has not arrived.

[0303] Then, the opening / closing control unit 54a of the control unit 50 waits until it is determined that the second return timing has arrived (SD7, No), and if it is determined that the second return timing has arrived (SD7, Yes), it proceeds to SD8.

[0304] In SD8, the switching control section 54a of the control unit 50 stops the execution of the second abnormality treatment control, and then proceeds to SD1.

[0305] Specifically, the opening / closing control unit 54a of the control unit 50 releases the restriction on the opening / closing movement of the opening / closing body 20 during the opening / closing process under the third abnormality restriction control, and transitions to processing SA1 during the opening / closing process, thereby enabling the opening / closing movement of the opening / closing body 20 to be performed based on the opening signal or the closing signal when an input of an opening signal or a closing signal is received from the operation unit 41 via the input unit 51 during the opening / closing process.

[0306] By performing the processes of SD7 and SD8, the opening and closing movement of the opening and closing body 20 can be performed safely as usual after the second return timing arrives, and the usability of the sliding door 1 can be ensured.

[0307] At SD9, the switching control section 54a of the control unit 50 determines whether or not the third abnormality occurrence timing has arrived.

[0308] Here, the "third abnormality occurrence timing" refers to the timing at which an abnormality that would not normally occur during the opening / closing process occurs in the fully open position detection unit 43 and / or the opening side deceleration position detection unit 45. In the embodiment, the third abnormality occurrence timing is described as the timing at which the fully open position detection unit 43 detects that the opening / closing body 20 has reached the fully open position, but the opening side deceleration position detection unit 45 does not detect that the opening / closing body 20 has reached the opening side deceleration position.

[0309] The reason why the third abnormality occurrence timing according to the embodiment is set to the above timing is as follows.

[0310] That is, as described above, when the opening-closing body 20 is located in a range from the opening-side deceleration position to the fully open position, the operation state of the opening-side deceleration position detection unit 45 is turned on, so when the opening-closing body 20 is located at the fully open position, the fully open position detection unit 43 detects that the opening-closing body 20 has reached the fully open position, and the opening-side deceleration position detection unit 45 detects that the opening-closing body 20 has reached the opening-side deceleration position. Based on this, in the opening and closing process, it is normally impossible for the fully open position detection unit 43 to detect that the opening-closing body 20 has reached the fully open position, but the opening-side deceleration position detection unit 45 does not detect that the opening-closing body 20 has reached the opening-side deceleration position, so the third abnormality occurrence timing according to the embodiment is set to the timing described above.

[0311] Furthermore, the method for determining whether the timing for the third abnormality to occur has arrived is arbitrary, but in the embodiment, when processing SD9, the determination is made based on whether input of a fully open position detection signal is received from the fully open position detection unit 43 via the input unit 51, but input of an open side deceleration position detection signal is not received from the open side deceleration position detection unit 45 via the input unit 51.

[0312] Here, if the input of the fully open position detection signal is accepted but the input of the open side deceleration position detection signal is not accepted, it is determined that the timing for the third abnormality to occur has arrived, and if the input of the fully open position detection signal is not accepted or the input of the open side deceleration position detection signal is accepted, it is determined that the timing for the third abnormality to occur has not arrived.

[0313] Then, if the opening / closing control unit 54a of the control unit 50 determines that the third abnormality occurrence timing has arrived (SD9, Yes), it proceeds to SD10, and if it determines that the third abnormality occurrence timing has not arrived (SD9, No), it proceeds to SD13.

[0314] In SD10, the opening / closing control section 54a of the control unit 50 determines that an abnormality has occurred in the fully open position detection section 43 and / or the open side deceleration position detection section 45, and executes third abnormality treatment control.

[0315] In this embodiment, the opening / closing control section 54a of the control unit 50 continues to execute the third abnormality treatment control until a third recovery timing, which will be described later, arrives.

[0316] Here, "third abnormality treatment control" means control related to treatment for the abnormality specified in SD10 (abnormality treatment control).

[0317] This third abnormality treatment control is a concept that includes, for example, first abnormality restriction control, second abnormality restriction control, third abnormality restriction control, abnormal opening control, abnormal closing control, abnormal stop control, and / or abnormal output control, but in the embodiment, it will be described as including third abnormality restriction control and abnormal output control.

[0318] For example, when the first abnormality limiting control, the second abnormality limiting control, or the third abnormality limiting control is performed, the opening / closing body 20 is not opened or closed based on the open signal or the close signal until the third return timing described below arrives, even if the opening or closing signal is received from the operation unit 41 via the input unit 51. Furthermore, when the abnormality output control is performed, notification information indicating that the third abnormality occurrence timing has arrived is output.

[0319] By processing SD9 and SD10 in this way, the third abnormality treatment control can be performed when an abnormality occurs in the fully open position detection unit 43 and / or the opening side deceleration position detection unit 45. Therefore, it is possible to quickly take measures against the abnormality identified in SD10, and it is possible to improve the safety when using the sliding door 1.

[0320] In SD11, the opening / closing control section 54a of the control unit 50 determines whether or not the third return timing has arrived.

[0321] Here, the "third return timing" refers to the timing (return timing) at which the state specified by SD10 returns to the state before the occurrence of the abnormality.

[0322] In the embodiment, this third return timing is described as the timing when repair work is first performed to repair the fully open position detection unit 43 and / or the opening side deceleration position detection unit 45, then the power to the sliding door 1 is turned back on, and then operation confirmation work is performed to check the operation of the fully open position detection unit 43 and / or the opening side deceleration position detection unit 45, and then the input of a return operation (hereinafter referred to as the "third return operation") is received via the operation unit 41.

[0323] However, the timing is not limited to this, and may be, for example, the timing when the input of the third reset operation is received via the operation unit 41 after the power to the sliding door 1 is turned back on and the operation check work is performed.

[0324] The method for determining whether or not this third return timing has arrived is arbitrary, but in this embodiment, the determination is made based on whether or not input of the third return operation has been accepted via the operating unit 41 since the power to the sliding door 1 was turned back on.

[0325] Here, if the input of the third reset operation is accepted after the power supply to the sliding door 1 is turned back on, it is determined that the third reset timing has arrived, and if the input of the third reset operation is not accepted after the power supply to the sliding door 1 is turned back on, it is determined that the third reset timing has not arrived.

[0326] Then, the opening / closing control unit 54a of the control unit 50 waits until it is determined that the third return timing has arrived (SD11, No), and if it is determined that the third return timing has arrived (SD11, Yes), it proceeds to SD12.

[0327] In SD12, the switching control section 54a of the control unit 50 stops the execution of the third abnormality treatment control, and then shifts to SD1.

[0328] Specifically, the opening / closing control unit 54a of the control unit 50 releases the restriction on the opening / closing movement of the opening / closing body 20 during the opening / closing process under the third abnormality restriction control, and transitions to processing SA1 during the opening / closing process, thereby enabling the opening / closing movement of the opening / closing body 20 to be performed based on the opening signal or the closing signal when an input of an opening signal or a closing signal is received from the operation unit 41 via the input unit 51 during the opening / closing process.

[0329] By performing the processes of SD11 and SD12 in this way, the opening and closing movement of the opening and closing body 20 can be performed safely as usual after the third return timing arrives, and the usability of the sliding door 1 can be ensured.

[0330] In SD13, the switching control section 54a of the control unit 50 determines whether or not the fourth abnormality occurrence timing has arrived.

[0331] Here, the "fourth abnormality occurrence timing" refers to the timing at which an abnormality that would not normally occur during the opening / closing process occurs in the fully open position detection unit 43 and / or the fully closed position detection unit 42. In the embodiment, the fourth abnormality occurrence timing is described as the timing at which the fully open position detection unit 43 detects that the opening / closing body 20 has reached the fully open position, and the fully closed position detection unit 42 detects that the opening / closing body 20 has reached the fully closed position.

[0332] The reason why the fourth abnormality occurrence timing according to the embodiment is set to the above timing is as follows.

[0333] 1, when the fully closed position detection unit 42 detects that the opening-closing body 20 has reached the fully closed position, the fully open position detection unit 43 does not detect that the opening-closing body 20 has reached the fully open position. Also, when the fully open position detection unit 43 detects that the opening-closing body 20 has reached the fully open position, the fully closed position detection unit 42 does not detect that the opening-closing body 20 has reached the fully closed position. In light of these facts, in the opening and closing process, it is normally impossible for the fully open position detection unit 43 to detect that the opening-closing body 20 has reached the fully open position and the fully closed position detection unit 42 to detect that the opening-closing body 20 has reached the fully closed position, so the fourth abnormality occurrence timing according to the embodiment is set to the timing described above.

[0334] Furthermore, the method for determining whether the timing for the fourth abnormality to occur has arrived is arbitrary, but in this embodiment, when processing SD13, the determination is made based on whether input of a fully open position detection signal and a fully closed position detection signal has been received from the fully open position detection unit 43 and the fully closed position detection unit 42 via the input unit 51.

[0335] Here, if the input of the fully open position detection signal and the fully closed position detection signal is accepted, it is determined that the fourth abnormality occurrence timing has arrived, and if the input of the fully open position detection signal or the fully closed position detection signal is not accepted, it is determined that the fourth abnormality occurrence timing has not arrived.

[0336] Then, if the opening / closing control unit 54a of the control unit 50 determines that the fourth abnormality occurrence timing has arrived (SD13, Yes), it proceeds to SD14, and if it determines that the fourth abnormality occurrence timing has not arrived (SD13, No), it proceeds to SD1.

[0337] Returning to FIG. 7, in SD14, the opening / closing control section 54a of the control unit 50 determines that an abnormality has occurred in the fully open position detection section 43 and / or the fully closed position detection section 42, and executes fourth abnormality treatment control.

[0338] In this embodiment, the opening / closing control section 54a of the control unit 50 continues to execute the fourth abnormality treatment control until a fourth recovery timing, which will be described later, arrives.

[0339] Here, the "fourth abnormality treatment control" means control related to treatment for the abnormality specified in SD14 (abnormality treatment control).

[0340] This fourth abnormality treatment control is a concept that includes, for example, first abnormality restriction control, second abnormality restriction control, third abnormality restriction control, abnormal opening control, abnormal closing control, abnormal stop control, and / or abnormal output control, but in the embodiment, it will be described as including third abnormality restriction control and abnormal output control.

[0341] For example, when the first abnormality limiting control, the second abnormality limiting control, or the third abnormality limiting control is performed, the opening / closing body 20 is not opened or closed based on the open signal or the close signal during the opening / closing process until the arrival of the fourth return timing described below, even if an open signal or a close signal is received from the operation unit 41 via the input unit 51. Furthermore, when the abnormality output control is performed, notification information indicating that the fourth abnormality occurrence timing has arrived is output.

[0342] By processing SD13 and SD14 in this way, the fourth abnormality treatment control can be performed when an abnormality occurs in the fully open position detection unit 43 and / or the fully closed position detection unit 42. Therefore, it is possible to quickly take measures against the abnormality identified in SD14, and it is possible to improve safety when using the sliding door 1.

[0343] At SD15, the opening / closing control section 54a of the control unit 50 determines whether or not the fourth return timing has arrived.

[0344] Here, the "fourth return timing" means the timing (return timing) at which the state specified by SD14 returns to the state before the occurrence of the abnormality.

[0345] In the embodiment, this fourth return timing is described as the timing when repair work is first performed to repair the fully open position detection unit 43 and / or the fully closed position detection unit 42, the power to the sliding door 1 is then turned back on, and operation confirmation work is performed to check the operation of the fully open position detection unit 43 and / or the fully closed position detection unit 42, and then the input of a return operation (hereinafter referred to as the "fourth return operation") is received via the operation unit 41.

[0346] However, the timing is not limited to this, and may be, for example, the timing when the input of the fourth reset operation is received via the operation unit 41 after the power to the sliding door 1 is turned back on and the operation check work is performed.

[0347] The method for determining whether or not this fourth return timing has arrived is arbitrary, but in this embodiment, the determination is made based on whether or not the input of the fourth return operation has been accepted via the operating unit 41 since the power to the sliding door 1 was turned back on.

[0348] Here, if the input of the fourth reset operation is accepted after the power supply to the sliding door 1 is turned back on, it is determined that the fourth reset timing has arrived, and if the input of the fourth reset operation is not accepted after the power supply to the sliding door 1 is turned back on, it is determined that the fourth reset timing has not arrived.

[0349] Then, the opening / closing control unit 54a of the control unit 50 waits until it is determined that the fourth return timing has arrived (SD15, No), and if it is determined that the fourth return timing has arrived (SD15, Yes), it proceeds to SD16.

[0350] At SD16, the switching control section 54a of the control unit 50 stops the execution of the fourth abnormality treatment control, and then proceeds to SD1, and thereafter similarly repeats the processes from SD1 to SD16.

[0351] Specifically, the opening / closing control unit 54a of the control unit 50 releases the restriction on the opening / closing movement of the opening / closing body 20 during the opening / closing process under the third abnormality restriction control, and transitions to processing SA1 during the opening / closing process, thereby enabling the opening / closing movement of the opening / closing body 20 to be performed based on the opening signal or the closing signal when an input of an opening signal or a closing signal is received from the operation unit 41 via the input unit 51 during the opening / closing process.

[0352] By performing the processes of SD15 and SD16 in this way, the opening and closing movement of the opening and closing body 20 can be performed safely as usual after the fourth return timing arrives, and the usability of the sliding door 1 can be ensured.

[0353] Furthermore, by performing the above-described abnormality processing, if an abnormality occurs in the fully closed position detection unit 42, the closing side deceleration position detection unit 44, the fully open position detection unit 43, and / or the opening side deceleration position detection unit 45, the sliding door 1 can be controlled in accordance with the abnormality, thereby increasing safety when using the sliding door 1.

[0354] (Processing - specific processing content) Next, specific processing contents in which processing according to the embodiment is executed will be described below.

[0355] (Processing - Specific processing content - First specific example) First, the first specific example will be described.

[0356] As a first specific example, in the fully open state, if an abnormality occurs in the opening side deceleration position detection unit 45 after the opening / closing process and abnormality process are activated, the following process is performed.

[0357] First, when the opening / closing body 20 is in the fully open position, the input of the fully open position detection signal and the opening side deceleration position detection signal is accepted, but the input of the fully closed position detection signal and the closing side deceleration position detection signal is not accepted. After that, when it is determined that the input of the closing signal is accepted in SA1 in Fig. 4, the closing process of SA2 in Fig. 4 is started and the closing control of SB1 in Fig. 5 is executed, thereby causing the opening / closing body 20 to move to the closing position.

[0358] Next, when the opening / closing body 20 is positioned between the opening side deceleration position and the closing side deceleration position due to the closing control of SB1 in Figure 5, an abnormality occurs in the opening side deceleration position detection unit 45, so that although the input of the opening side deceleration position detection signal is accepted, the input of the fully open position detection signal, the fully closed position detection signal, and the closing side deceleration position detection signal is not accepted.

[0359] Next, when the opening / closing body 20 is positioned at the closing side deceleration position due to the closing control of SB5 in Figure 5, an abnormality occurs in the opening side deceleration position detection unit 45, so that the input of the opening side deceleration position detection signal and the closing side deceleration position detection signal is accepted, but the input of the fully open position detection signal and the fully closed position detection signal is not accepted.

[0360] As a result, it is determined at SD1 in Figure 7 that the first abnormality occurrence timing has arrived, and the first abnormality treatment control (specifically, the second abnormality restriction control and the abnormality output control) is executed at SD2 in Figure 7, so that after the opening / closing body 20 moves to the fully closed position and stops, the opening / closing movement of the opening / closing body 20 is restricted until the first return timing arrives, and alarm information is output.

[0361] Next, when it is determined that the first return timing has arrived at SD3 in Fig. 7 due to the return to the state before the abnormality occurred in the opening-side deceleration position detection unit 45, execution of the first abnormality treatment control is stopped at SD4 in Fig. 7. After that, when it is determined that input of the open signal has been accepted at SA3 in Fig. 4, the opening process at SA4 in Fig. 4 is started and the opening control at SC1 in Fig. 6 is executed, causing the opening-closing body 20 to move to the open position.

[0362] Subsequently, as described above, the opening side deceleration position detection unit 45 has returned to the state before the abnormality occurred, so while the opening control of SC1 in Figure 6 (or the opening side deceleration control of SC3 in Figure 6) is being executed, the opening / closing body 20 moves to the fully open position without any abnormality treatment control being executed.

[0363] By processing corresponding to this first specific example, if an abnormality occurs in the opening side deceleration position detection unit 45, the first abnormality treatment control can be performed, thereby increasing safety when using the sliding door 1.

[0364] (Processing - Specific processing content - Second specific example) Next, the second specific example will be described.

[0365] As a second specific example, in the fully open state, if an abnormality occurs in the closing side deceleration position detection unit 44 after the opening / closing process and abnormality process are activated, the following process is performed.

[0366] First, when the opening / closing body 20 is in the fully open position, the input of the fully open position detection signal and the opening side deceleration position detection signal is accepted, but the input of the fully closed position detection signal and the closing side deceleration position detection signal is not accepted. After that, when it is determined that the input of the closing signal is accepted in SA1 in Fig. 4, the closing process of SA2 in Fig. 4 is started, and the closing control of SB1 in Fig. 5 is executed.

[0367] Next, when the opening / closing body 20 is positioned between the opening side deceleration position and the closing side deceleration position due to the closing control of SB1 in Figure 5, the input of the fully open position detection signal, the fully closed position detection signal, the opening side deceleration position detection signal, and the closing side deceleration position detection signal is not accepted.

[0368] Next, when the opening / closing body 20 is positioned at the closing side deceleration position due to the closing control of SB1 in Figure 5, an abnormality occurs in the closing side deceleration position detection unit 44, and a state is maintained in which the input of the fully open position detection signal, the fully closed position detection signal, the opening side deceleration position detection signal, and the closing side deceleration position detection signal is not accepted.

[0369] Next, when the opening / closing body 20 is positioned in the fully closed position due to the closing side deceleration control of SB5 in Figure 5, an abnormality occurs in the closing side deceleration position detection unit 44, so that although the input of the fully closed position detection signal is accepted, the input of the fully open position detection signal, the opening side deceleration position detection signal, and the closing side deceleration position detection signal is not accepted.

[0370] As a result, it is determined at SD5 in Figure 7 that the second abnormality occurrence timing has arrived, and the second abnormality treatment control (specifically, the third abnormality restriction control and the abnormality output control) is executed at SD6 in Figure 7, so that after the closing movement of the opening / closing body 20 stops, the opening / closing movement of the opening / closing body 20 is restricted until the first return timing arrives, and alarm information is output.

[0371] Next, when it is determined that the second return timing has arrived at SD7 in Fig. 7 due to the closing side deceleration position detection unit 44 returning to the state before the abnormality occurred, the execution of the second abnormality treatment control is stopped at SD8 in Fig. 7. After that, when it is determined that the input of the open signal has been received at SA3 in Fig. 4, the opening process at SA4 in Fig. 4 is started, and the opening control at SC1 in Fig. 6 is executed, causing the opening / closing body 20 to move to the open position.

[0372] Subsequently, as described above, the closing side deceleration position detection unit 44 has returned to the state before the abnormality occurred, so while the opening control of SC1 in Figure 6 (or the opening side deceleration control of SC3 in Figure 6) is being executed, the opening / closing body 20 moves to the fully open position without various abnormality treatment controls being executed.

[0373] By processing corresponding to this second specific example, a second abnormality treatment control can be performed if an abnormality occurs in the closing side deceleration position detection unit 44, thereby increasing safety when using the sliding door 1.

[0374] (Processing - Specific processing content - Third specific example) Next, the third specific example will be described.

[0375] As a third specific example, in the fully closed state, if an abnormality occurs in the opening side deceleration position detection unit 45 after the opening / closing process and abnormality process are activated, the following process is performed.

[0376] First, when the opening / closing body 20 is in the fully closed position, the input of the fully closed position detection signal and the closing side deceleration position detection signal is accepted, but the input of the fully open position detection signal and the opening side deceleration position detection signal is not accepted. After that, when it is determined that the input of the opening signal is accepted in SA3 of Fig. 4, the opening process of SA4 of Fig. 4 is started and the opening control of SC1 of Fig. 6 is executed, thereby causing the opening movement of the opening / closing body 20.

[0377] Next, when the opening control of SC1 in Figure 6 causes the opening / closing body 20 to be positioned between the opening side deceleration position and the closing side deceleration position, the input of the fully open position detection signal, the fully closed position detection signal, the opening side deceleration position detection signal, and the closing side deceleration position detection signal is not accepted.

[0378] Next, when the opening control of SC1 in Figure 6 causes the opening / closing body 20 to be positioned at the opening side deceleration position, an abnormality occurs in the opening side deceleration position detection unit 45, and a state is maintained in which the input of the fully open position detection signal, the fully closed position detection signal, the opening side deceleration position detection signal, and the closing side deceleration position detection signal is not accepted.

[0379] Next, when the opening-closing body 20 is positioned in the fully open position due to the opening-side deceleration control of SC3 in Figure 6, an abnormality occurs in the opening-side deceleration position detection unit 45, so that although the input of the fully open position detection signal is accepted, the input of the fully closed position detection signal, the opening-side deceleration position detection signal, and the closing-side deceleration position detection signal is not accepted.

[0380] As a result, it is determined at SD9 in Figure 7 that the third abnormality occurrence timing has arrived, and the third abnormality treatment control (specifically, the third abnormality restriction control and the abnormality output control) is executed at SD10 in Figure 7, so that after the opening movement of the opening / closing body 20 stops, the opening / closing movement of the opening / closing body 20 is restricted until the third return timing arrives, and alarm information is output.

[0381] Next, when it is determined that the third return timing has arrived at SD11 in Fig. 7 due to the return to the state before the abnormality occurred in the opening side deceleration position detection unit 45, execution of the third abnormality treatment control is stopped at SD12 in Fig. 7. After that, when it is determined that the input of the close signal has been accepted at SA1 in Fig. 4, the close processing at SA2 in Fig. 4 is started, and the close control at SB1 in Fig. 5 is executed, causing the opening / closing body 20 to move to the closed position.

[0382] Subsequently, as described above, the opening side deceleration position detection unit 45 has returned to the state before the abnormality occurred, so while the closing control of SB1 in Figure 5 (or the closing side deceleration control of SB5 in Figure 5, or the pressing control of SB9 in Figure 5) is being executed, the opening / closing body 20 moves to the fully closed position without various abnormality treatment controls being executed.

[0383] By processing corresponding to this third specific example, third abnormality treatment control can be performed if an abnormality occurs in the opening side deceleration position detection unit 45, thereby increasing safety when using the sliding door 1.

[0384] (Processing - Specific processing content - Fourth specific example) Next, the fourth specific example will be described.

[0385] As for the fourth specific example, if an abnormality occurs in the fully closed position detection unit 42 after the opening / closing process and the abnormality process are activated in the fully closed state, the following process is performed.

[0386] First, when the opening / closing body 20 is in the fully closed position, the input of the fully closed position detection signal and the closing side deceleration position detection signal is accepted, but the input of the fully open position detection signal and the opening side deceleration position detection signal is not accepted. After that, when it is determined that the input of the opening signal is accepted in SA3 of Fig. 4, the opening process of SA4 of Fig. 4 is started and the opening control of SC1 of Fig. 6 is executed, thereby causing the opening movement of the opening / closing body 20.

[0387] Next, when the opening / closing body 20 is positioned in the fully open position due to the opening control of SC1 in Figure 6, an abnormality occurs in the fully closed position detection unit 42, so that the input of the fully closed position detection signal and the fully open position detection signal is accepted, but the input of the closing side deceleration position detection signal and the opening side deceleration position detection signal is not accepted.

[0388] As a result, it is determined at SD13 in Figure 7 that the fourth abnormality occurrence timing has arrived, and the fourth abnormality treatment control (specifically, the third abnormality restriction control and the abnormality output control) is executed at SD14 in Figure 7, so that after the opening movement of the opening / closing body 20 stops, the opening / closing movement of the opening / closing body 20 is restricted until the fourth return timing arrives, and alarm information is output.

[0389] Next, when it is determined that the fourth return timing has arrived at SD15 in Fig. 7 due to the full-close position detection unit 42 returning to the state before the abnormality occurred, execution of the fourth abnormality treatment control is stopped at SD16 in Fig. 7. After that, when it is determined that input of the open signal has been accepted at SA3 in Fig. 4, the opening process at SA4 in Fig. 4 is started, and the opening control at SC1 in Fig. 6 is executed, thereby causing the opening body 20 to move to the open position.

[0390] Subsequently, as described above, the fully closed position detection unit 42 has returned to the state before the abnormality occurred, so while the opening control of SC1 in Figure 6 (or the opening side deceleration control of SC3 in Figure 6) is being executed, the opening / closing body 20 moves to the fully open position without various abnormality treatment controls being executed.

[0391] By processing corresponding to this fourth specific example, a fourth abnormality treatment control can be performed if an abnormality occurs in the fully closed position detection unit 42, thereby increasing safety when using the sliding door 1.

[0392] Regarding the fourth specific example, substantially the same processing is performed, for example, when an abnormality occurs in the fully open position detection unit 43 after the opening / closing processing and the abnormality processing are started.

[0393] (Effects of the embodiment) As described above, according to the embodiment, when the opening-side deceleration position detection unit 45 detects that the opening-side body 20 has reached the opening-side deceleration position and the closing-side deceleration position detection unit 44 detects that the opening-side body 20 has reached the closing-side deceleration position, the opening-closing control unit 54a determines that an abnormality has occurred in the opening-side deceleration position detection unit 45 and / or the closing-side deceleration position detection unit 44 and performs abnormality treatment control, so that abnormality treatment control can be performed when an abnormality has occurred in the opening-side deceleration position detection unit 45 and / or the closing-side deceleration position detection unit 44. Therefore, treatment can be quickly taken for the abnormality, and safety during use of the sliding door 1 can be improved.

[0394] Furthermore, the abnormality treatment control performed when the opening / closing body 20 is moving in the open direction includes the first abnormality restriction control, so if an abnormality occurs in the opening side deceleration position detection unit 45 and / or the closing side deceleration position detection unit 44 during the opening movement of the opening / closing body 20, the first abnormality restriction control can be performed, and it is possible to avoid the opening / closing body 20 moving in an unusual manner until the return timing arrives.

[0395] Furthermore, the abnormality treatment control performed when the opening / closing body 20 is moving in the closing direction includes the second abnormality restriction control, so if an abnormality occurs in the opening side deceleration position detection unit 45 and / or the closing side deceleration position detection unit 44 during the closing movement of the opening / closing body 20, the second abnormality restriction control can be performed, and it is possible to avoid the opening / closing body 20 moving in an unusual manner until the return timing arrives.

[0396] Furthermore, the opening / closing control unit 54a performs abnormality treatment control when the fully open position detection unit 43 detects that the opening / closing body 20 has reached the fully open position and when the fully closed position detection unit 42 detects that the opening / closing body 20 has reached the fully closed position, so that abnormality treatment control can be performed when an abnormality occurs in the fully open position detection unit 43 and / or the fully closed position detection unit 42. Therefore, treatment can be taken quickly in response to the abnormality, and the safety of the sliding door 1 when in use can be further improved.

[0397] Furthermore, when the first detection means detects that the opening / closing body 20 has reached the fully open position or the fully closed position, but the second detection means does not detect that the opening / closing body 20 has reached a deceleration position located just before the fully open position or the fully closed position detected by the first detection means, the opening / closing control unit 54a determines that an abnormality has occurred in the first detection means and / or the second detection means, and performs abnormality treatment control, so that abnormality treatment control can be performed when an abnormality has occurred in the first detection means and / or the second detection means. Therefore, treatment can be taken quickly for the abnormality, and safety during use of the sliding door 1 can be improved.

[0398] Furthermore, the opening / closing control unit 54a performs abnormality treatment control when the fully open position detection unit 43 detects that the opening / closing body 20 has reached the fully open position and when the fully closed position detection unit 42 detects that the opening / closing body 20 has reached the fully closed position, so that abnormality treatment control can be performed when an abnormality occurs in the fully open position detection unit 43 and / or the fully closed position detection unit 42. Therefore, treatment can be taken quickly in response to the abnormality, and the safety of the sliding door 1 when in use can be further improved.

[0399] [III] Modifications to the embodiment Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions set forth in the claims. Such modifications will be described below.

[0400] (About the problem to be solved and the effects of the invention) First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and the present invention may solve problems that are not described above or achieve effects that are not described above, or may solve only some of the problems that are described or achieve only some of the effects that are described.

[0401] (Regarding decentralization and integration) Furthermore, the electrical components described above are functional concepts and do not necessarily have to be physically configured as shown in the drawings. In other words, the specific form of distribution or integration of each part is not limited to that shown in the drawings, and all or part of them can be functionally or physically distributed or integrated in any unit depending on various loads, usage conditions, etc. Furthermore, the term "device" in this application is not limited to a single device, but includes a device configured from multiple devices.

[0402] For example, the control unit 50 according to the embodiment may be distributed among multiple devices that are configured to be able to communicate with each other, with a control unit 54 provided in some of the devices and a memory unit 55 provided in another part of the devices.

[0403] (shape, numbers, structure, time series) The components illustrated in the embodiments and drawings may be modified and improved as desired within the scope of the technical concept of the present invention in terms of shape, numerical value, or the structure or chronological relationship of multiple components.

[0404] (Opening and closing control system) In the above embodiment, the opening / closing control system 40 is described as being equipped with a closing side deceleration position detection unit 44, an opening side deceleration position detection unit 45, a first obstacle detection unit 46 (or a second obstacle detection unit 47), and an opening / closing output unit 48, but this is not limited to this, and for example, the closing side deceleration position detection unit 44, the opening side deceleration position detection unit 45, the second obstacle detection unit 47, and / or the opening / closing output unit 48 may be omitted.

[0405] Here, if the second obstacle detection unit 47 is omitted, the first obstacle detection unit 46 may be configured so that the detection range of the first obstacle detection unit 46 includes the entire area in which the opening / closing body 20 is moved open and closed.

[0406] As an example, as shown in Figure 8, the first obstacle detection unit 46 may be configured so that the light-transmitting unit 46a is located at or near the left end of the opening 3, and the light-receiving unit 46b is located near the open-side door stop 17.

[0407] With this configuration, even if only a non-contact type obstacle detection sensor is installed, obstacles can be detected accurately, and the installation cost of the obstacle detection means can be reduced.

[0408] Furthermore, when the closing side deceleration position detection unit 44 and the first obstacle detection unit 46 (or the second obstacle detection unit 47) are omitted, SB4 to SB7 of the closing process and SC2 and SC3 of the opening process may be omitted. Alternatively, the first avoidance control (or second avoidance control) of SB3 and SB7 may be omitted.

[0409] Incidentally, by omitting the processes of SC2 and SC3 (i.e., when the opening / closing body 20 is moving in the open position and the opening-side deceleration control is not being performed, the opening / closing control section 54a of the control unit 50 does not perform the avoidance control regardless of the detection result of the first obstacle detection section 46 or the second obstacle detection section 47), when the opening / closing body 20 is moving in the open position and the opening-side deceleration control is not being performed, it is possible to avoid the obstacle from blocking the passage of the target through the opening 3 due to the avoidance control, and ensure the usability of the sliding door 1. Furthermore, it is possible to avoid harm to the target by the opening / closing body 20 (such as the target being pinched by the opening / closing body 20 or a collision between the opening / closing body 20 and the target), and it is possible to improve the safety when using the sliding door 1.

[0410] Furthermore, when the release side deceleration position detector 45 is omitted, SC4 to SC7 of the release process may be omitted.

[0411] (About various detection units) In the above embodiment, the fully closed position detection unit 42, the fully open position detection unit 43, the closing side deceleration position detection unit 44, and the opening side deceleration position detection unit 45 are described as self-holding proximity switches, but this is not limited to this and they may also be, for example, non-self-holding proximity switches.

[0412] Furthermore, in the above embodiment, it has been explained that the fully closed position detection unit 42 is provided inside the transom 13 at a position corresponding to the end of the opening 3 in the closing direction or its vicinity, and the fully open position detection unit 43 is provided inside the transom 13 at a position corresponding to the end of the opening 3 in the opening direction or its vicinity, but this is not limited to this.

[0413] For example, the fully closed position detection unit 42 may be provided inside the transom 13 at a position corresponding to the end of the opening direction side of the opening 3 or its vicinity, and the fully open position detection unit 43 may be provided inside the transom 13 at a position corresponding to the opening side door stop 17 or its vicinity. In this case, the magnet unit provided on the opening / closing body 20 may be provided at the trailing edge of the upper end of the opening / closing body 20 or its vicinity.

[0414] Alternatively, the fully closed position detection unit 42 may be provided inside the transom 13 at a position corresponding to the end of the opening 3 in the closing direction or its vicinity, and the fully open position detection unit 43 may be provided inside the transom 13 at a position corresponding to the opening-side door stop 17 or its vicinity. In this case, the magnet units provided on the opening / closing body 20 may be provided at the leading end or its vicinity of the upper end of the opening / closing body 20, and at the trailing end or its vicinity.

[0415] In the above embodiment, the first obstacle detector 46 is described as a photoelectric sensor, but is not limited to this. For example, it may be a non-contact obstacle detection sensor other than a photoelectric sensor (e.g., an infrared sensor, a microwave sensor, a transmission type photoelectric sensor, etc.).

[0416] In the above embodiment, the second obstacle detector 47 is described as an overload detection sensor, but is not limited to this. For example, the second obstacle detector 47 may be a contact-type obstacle detection sensor other than an overload detection sensor (e.g., a contact-type displacement sensor, a pressure sensor, etc.).

[0417] (About opening and closing process) In the above embodiment, the opening process or closing process is performed based on the opening signal or closing signal received as input from the operation unit 41 via the input unit 51, but the present invention is not limited to this.

[0418] For example, the opening process may be performed based on an opening signal input from the operation unit 41 via the input unit 51. Furthermore, the closing process may be performed immediately after the opening process is completed, or after a predetermined time has elapsed since the opening process was completed.

[0419] Alternatively, instead of the operation unit 41, if detection means (for example, a photoelectric sensor or an infrared sensor) for detecting a passing object located near the opening 3 are provided at a position outside the building and a position inside the building, the opening process may be performed when the passing object is detected by the detection means. Also, the closing process may be performed immediately after the opening process is completed, or after a predetermined time has elapsed since the opening process was completed.

[0420] (About the closure process) In the above embodiment, it was explained that in SB9, the opening / closing control unit 54a of the control unit 50 performs pressing control, but this is not limited to this, and for example, control to stop the closing movement of the opening / closing body 20 (hereinafter referred to as "closing side stop control") may also be performed.

[0421] In this case, for example, the processes from SB10 to SB12 may be omitted, and the opening / closing control section 54a of the control unit 50 may end the closing process after the closing side stop control is performed.

[0422] (About the release process) In the above embodiment, it has been explained that the processes of SC6 and SC7 are performed, but this is not limiting, and for example, the processes of SC6 and SC7 may be omitted.

[0423] Furthermore, in the above embodiment, it was explained that the opening / closing control unit 54a of the control unit 50 does not perform avoidance control based on the first obstacle detection unit 46 when the opening / closing body 20 is moving in the open position and opening side deceleration control is not being performed, but this is not limited to this.

[0424] For example, when the opening / closing body 20 is moving in the open position and the opening-side deceleration control is not being performed, the opening / closing control section 54a of the control unit 50 may not perform the avoidance control regardless of the detection results of the first obstacle detection section 46 and the second obstacle detection section 47. In this case, the processes of SC2 and SC3 may be omitted.

[0425] As a result, when the opening / closing body 20 is moving to open and the opening-side deceleration control is not being performed, it is possible to avoid the avoidance control from obstructing the passage of the pass-through object through the opening 3, thereby ensuring the usability of the sliding door 1. It is also possible to avoid harm to the pass-through object caused by the opening / closing body 20 (such as the pass-through object being pinched by the opening / closing body 20 or a collision between the opening / closing body 20 and the pass-through object), thereby making it possible to improve safety when using the sliding door 1.

[0426] Alternatively, when avoidance control is performed to prevent the passage of the object through the opening 3 from being obstructed and / or to prevent harm to the object by the opening / closing body 20, the opening / closing control unit 54a of the control unit 50 may perform the avoidance control based on the detection results of the first obstacle detection unit 46 and / or the second obstacle detection unit 47.

[0427] (Regarding abnormality processing) In the above embodiment, it has been explained that the processes from SD1 to SD16 are executed, but this is not limiting, and for example, some of the processes from SD1 to SD16 may be omitted.

[0428] As an example, the processes SD1 to SD4 may be omitted. In other words, the opening / closing control unit 54a may not perform the first abnormality treatment control when the opening / closing deceleration position detection unit 45 detects that the opening / closing body 20 has reached the opening / closing deceleration position and the closing / closing deceleration position detection unit 44 detects that the opening / closing body 20 has reached the closing / closing deceleration position.

[0429] Alternatively, the processes from SD5 to SD8 may be omitted. In other words, the opening / closing control unit 54a may not perform the second abnormality treatment control when the fully closed position detection unit 42 detects that the opening / closing body 20 has reached the fully closed position, but the closing side deceleration position detection unit 44 does not detect that the opening / closing body 20 has reached the closing side deceleration position.

[0430] Alternatively, the processes from SD9 to SD12 may be omitted. In other words, the opening / closing control unit 54a may not perform the third abnormality treatment control when the fully open position detection unit 43 detects that the opening / closing body 20 has reached the fully open position, but the opening side deceleration position detection unit 45 does not detect that the opening / closing body 20 has reached the opening side deceleration position.

[0431] Alternatively, the processes from SD13 to SD16 may be omitted. In other words, the opening / closing control unit 54a may not perform the fourth abnormality treatment control when the fully open position detection unit 43 detects that the opening / closing body 20 has reached the fully open position and the fully closed position detection unit 42 detects that the opening / closing body 20 has reached the fully closed position.

[0432] (Regarding abnormality control) In the above embodiment, the first abnormality treatment control, the second abnormality treatment control, the third abnormality treatment control, and the fourth abnormality treatment control are described as including the abnormality output control, but this is not limited to this, and for example, the abnormality output control may be omitted.

[0433] Furthermore, in the above embodiment, the first abnormality treatment control is described as including the first abnormality restriction control, the second abnormality restriction control, and the abnormality output control, but is not limited to this, and for example, instead of the first abnormality restriction control, the second abnormality restriction control, and the abnormality output control, it may include the abnormality opening control, the abnormality closing control, or the abnormality stopping control.

[0434] (Addendum) The opening / closing control system of Supplementary Note 1 is an opening / closing body constituting a sliding door provided at an opening of a building, and is an opening / closing control system for controlling opening / closing movement of the opening / closing body that opens and closes the opening, and comprises: an opening-side detection means used to safely stop the opening movement at a fully open position that is a position corresponding to a state in which the opening is fully opened by the opening / closing body when the opening / closing body is moved to close; a closing-side detection means used to safely stop the closing movement at a fully closed position that is a position corresponding to a state in which the opening is fully closed by the opening / closing body when the opening / closing body is moved to close; and an opening / closing control means that controls the opening / closing movement of the opening / closing body based on the detection results of the opening-side detection means and the detection results of the closing-side detection means, The detection means includes an opening side deceleration position detection means that detects whether the opening / closing body has reached an opening side deceleration position that is located just before the fully open position, and the closing side detection means includes a closing side deceleration position detection means that detects whether the opening / closing body has reached a closing side deceleration position that is located just before the fully closed position, and when the opening side deceleration position detection means detects that the opening / closing body has reached the opening side deceleration position and the closing side deceleration position detection means detects that the opening / closing body has reached the closing side deceleration position, the opening / closing control means determines that an abnormality has occurred in the opening side deceleration position detection means and / or the closing side deceleration position detection means, and performs abnormality treatment control, which is control related to treatment for the determined abnormality.

[0435] The opening / closing control system of Appendix 2 is the opening / closing control system described in Appendix 1, wherein the abnormality treatment control performed when the opening / closing body is moving in an open position includes a first abnormality restriction control that restricts the opening / closing movement of the opening / closing body after moving the opening / closing body in an open position until the return timing arrives for returning to the state before the abnormality occurred.

[0436] The opening / closing control system of Appendix 3 is the opening / closing control system described in Appendix 1, wherein the abnormality treatment control performed when the opening / closing body is moving in the closed position includes a second abnormality restriction control that restricts the opening / closing movement of the opening / closing body after moving the opening / closing body in the closed position until the return timing arrives for returning to the state before the abnormality occurred.

[0437] The opening / closing control system of Appendix 4 is an opening / closing control system described in any one of Appendixes 1 to 3, wherein the opening side detection means comprises a fully open position detection means that detects whether the opening / closing body has reached the fully open position, and the closing side detection means comprises a fully closed position detection means that detects whether the opening / closing body has reached the fully closed position, and the opening / closing control means performs the abnormality treatment control when the fully open position detection means detects that the opening / closing body has reached the fully open position and the fully closed position detection means detects that the opening / closing body has reached the fully closed position.

[0438] The opening / closing control system of Supplementary Note 5 is an opening / closing body constituting a sliding door provided at an opening of a building, and is an opening / closing control system for controlling the opening / closing movement of the opening / closing body that opens and closes the opening, and comprises: an opening-side detection means used to safely stop the opening movement at a fully open position, which is a position corresponding to a state in which the opening is fully opened by the opening / closing body, when the opening / closing body is moved to close, the closing movement at a fully closed position, which is a position corresponding to a state in which the opening is fully closed by the opening / closing body, and an opening / closing control means that controls the opening / closing movement of the opening / closing body based on the detection results of the opening-side detection means and the detection results of the closing-side detection means, and The closing side detection means includes a first detection means that detects whether the opening / closing body has reached the fully open position or the fully closed position, and a second detection means that detects whether the opening / closing body has reached the fully open position or the deceleration position located just before the fully closed position. If the first detection means detects that the opening / closing body has reached the fully open position or the fully closed position, but the second detection means does not detect that the opening / closing body has reached the fully open position or the deceleration position located just before the fully closed position detected as having been reached by the first detection means, the opening / closing control means determines that an abnormality has occurred in the first detection means and / or the second detection means, and performs abnormality treatment control, which is control related to treatment for the determined abnormality.

[0439] The opening / closing control system of Appendix 6 is the opening / closing control system described in Appendix 5, wherein the first detection means includes a fully open position detection means that detects whether the opening / closing body has reached the fully open position, and a fully closed position detection means that detects whether the opening / closing body has reached the fully closed position, and the opening / closing control means performs the abnormality treatment control when the fully open position detection means detects that the opening / closing body has reached the fully open position and the fully closed position detection means detects that the opening / closing body has reached the fully closed position.

[0440] (Effect of supplementary notes) According to the opening / closing control system described in Supplementary Note 1, when the opening-side deceleration position detection means detects that the opening / closing body has reached the opening-side deceleration position and the closing-side deceleration position detection means detects that the opening / closing body has reached the closing-side deceleration position, the opening / closing control means determines that an abnormality has occurred in the opening-side deceleration position detection means and / or the closing-side deceleration position detection means and performs abnormality treatment control, so that abnormality treatment control can be performed when an abnormality has occurred in the opening-side deceleration position detection means and / or the closing-side deceleration position detection means. Therefore, treatment can be taken quickly for the abnormality, and safety during use of the sliding door can be improved.

[0441] According to the opening / closing control system described in Appendix 2, the abnormality treatment control performed when the opening / closing body is moving in the open position includes the first abnormality restriction control, so that if an abnormality occurs in the opening side deceleration position detection means or / and the closing side deceleration position detection means during the opening movement of the opening / closing body, the first abnormality restriction control can be performed, thereby preventing the opening / closing body from moving in an unusual manner until the return timing arrives.

[0442] According to the opening / closing control system described in Appendix 3, the abnormality treatment control performed when the opening / closing body is moving in the closing direction includes the second abnormality limiting control, so that if an abnormality occurs in the opening side deceleration position detection means and / or the closing side deceleration position detection means during the closing movement of the opening / closing body, the second abnormality limiting control can be performed, thereby preventing the opening / closing body from moving in an unusual manner until the return timing arrives.

[0443] According to the opening / closing control system described in Supplementary Note 4, the opening / closing control means performs abnormality treatment control when the fully open position detection means detects that the opening / closing body has reached the fully open position and the fully closed position detection means detects that the opening / closing body has reached the fully closed position, so abnormality treatment control can be performed when an abnormality occurs in the fully open position detection means and / or the fully closed position detection means. Therefore, treatment can be taken quickly in response to the abnormality, further increasing safety when using the sliding door.

[0444] According to the opening / closing control system described in Supplementary Note 5, when the first detection means detects that the opening / closing body has reached the fully open position or the fully closed position, but the second detection means does not detect that the opening / closing body has reached a deceleration position located before the fully open position or the fully closed position detected by the first detection means, the opening / closing control means determines that an abnormality has occurred in the first detection means and / or the second detection means, and performs abnormality treatment control, so that abnormality treatment control can be performed when an abnormality has occurred in the first detection means and / or the second detection means. Therefore, treatment can be taken quickly for the abnormality, and safety during use of the sliding door can be improved.

[0445] According to the opening / closing control system described in Supplementary Note 6, the opening / closing control means performs abnormality treatment control when the fully open position detection means detects that the opening / closing body has reached the fully open position and the fully closed position detection means detects that the opening / closing body has reached the fully closed position, so abnormality treatment control can be performed when an abnormality occurs in the fully open position detection means and / or the fully closed position detection means. Therefore, treatment can be taken quickly in response to the abnormality, further increasing safety when using the sliding door. [Explanation of symbols]
