Description

  The present invention relates to a sliding door control device for a vehicle door for preventing the sliding door from contacting an obstacle during opening and closing.

The invention of Patent Document 1 is an invention related to an automobile including a slide door and an openable / closable fuel lid, and when the fuel lid switch detects the open state of the fuel lid, the slide door is not slid to the fully open position in contact with the fuel lid. It is stopped in front of the fully open position where it does not contact the fuel lid.
JP-A-7-76220

Thus, the invention of Patent Document 1 can prevent the sliding door from coming into contact with the fuel lid in the open state.
However, the sliding door of the invention of Patent Document 1 does not include a sensor for detecting an obstacle such as a fuel lid. Therefore, if the sliding door is slid in the opening direction when the fuel lid is closed, the opening direction side end surface of the sliding door may contact a passenger or the like standing behind the sliding door. Furthermore, in a state where the fuel lid is closed, there is also a problem that even if a passenger's clothes are sandwiched between the sliding door and the door opening, this cannot be detected.

In addition, by attaching a non-contact sensor (for example, a capacitive non-contact sensor) whose sensitivity is kept constant on the end surface of the sliding door in the opening direction, the sliding door is opened when sliding in the opening direction. It is conceivable that not only the fuel lid in FIG. 6 but also passengers standing on the opening direction side of the sliding door are sensed and the sliding control is performed so that the sliding door does not contact these obstacles.
However, if the sensitivity of the non-contact sensor is always kept constant regardless of the open / close state of the fuel lid, the amount of energy consumed by the non-contact sensor increases. Further, when the sliding door reaches the fully closed position, the non-contact sensor may erroneously detect the facing portion of the door opening.

  The object of the present invention is to reliably prevent the sliding door sliding in the opening direction from coming into contact with an obstacle regardless of whether or not the fuel lid is in an open state, and to reduce the energy consumption of the sensor. In addition, it is an object of the present invention to provide a sliding door control device for a vehicle door in which a sensor does not cause erroneous detection when the sliding door moves to a fully closed position.

  A sliding door control device for a vehicle door according to the present invention includes a sliding direction detection means for detecting whether a sliding door slidably supported on a vehicle body is sliding in an opening direction or a closing direction, and is freely openable and closable to the vehicle body. An open / close state detection means for detecting whether or not a fuel lid located on the opening direction side of the slide door as viewed from the door opening of the vehicle body is in an open state, and an opening direction end surface of the slide door. A non-contact sensor capable of adjusting the sensitivity for detecting the presence of an obstacle, and when the open / close state detecting means detects an open state of the fuel lid and the slide direction detecting means detects an open direction slide, Compared with the case where the open / closed state detecting means detects the closed state or the sliding direction detecting means detects the sliding in the closing direction, the non-contact type sensor feels. It is characterized by comprising a sensor sensitivity adjusting means to increase the sensitivity, the.

When the open / close state detection means detects a closed state or the slide direction detection means detects a slide in the close direction, the sensor sensitivity adjustment means detects that the non-contact sensor is a vehicle when the slide door is located at the fully closed position. It is preferable to lower the sensitivity of the non-contact type sensor to a level at which the opposing part on the body side is not sensed.
In this case, the non-contact sensor may be switched to the contact mode.

  When the non-contact sensor senses the fuel lid by sliding the sliding door in the opening direction with the fuel lid being open, reverse driving means is provided for sliding the sliding door to the closing position to a specified position. Is preferred.

According to the present invention, the non-contact sensor senses an obstacle regardless of whether the fuel lid is opened, regardless of whether the fuel lid is opened or not. It is possible to prevent the slide operation from continuing while being performed.
In particular, when the fuel lid is in the open state and the slide door is sliding in the opening direction, the detection sensitivity of the non-contact sensor is increased, so that the slide door can be reliably prevented from coming into contact with the fuel lid. Furthermore, when an obstacle such as clothes is sandwiched between the sliding door and the door opening, the non-contact sensor senses the sandwiched state, and thus the sandwiched state can be quickly eliminated.

In addition, the sensitivity of the non-contact type sensor is not affected when the slide door is not in contact with the fuel lid, that is, when the fuel lid is in the closed state and when the fuel lid is in the open state and the slide door slides in the closing direction. It is low. Therefore, when the sliding door is slid to the fully closed position, the non-contact sensor erroneously detects the opening edge (opposite part) of the door opening, and the sliding door has an obstacle (clothing) between the opening edge of the door opening. Etc.), the sliding door can be prevented from being accidentally slid in the opening direction.
Furthermore, by reducing the sensitivity of the non-contact type sensor, the energy (electric power) for operating the non-contact type sensor can be suppressed as compared with the case where the fuel lid is in the open state and the sliding door slides in the opening direction. Energy saving can be achieved.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In addition, the front and rear directions in the following description are based on the direction of the arrow described in FIG.
The door opening 11 is formed in the vehicle body side surface of the motor vehicle 10, and the weather strip WS is stuck to the whole peripheral part of the door opening 11 (refer FIG.3 and FIG.4). Three slide rails 13 and 14 extending in the front-rear direction are provided at both upper and lower edges of the door opening 11 and a rear portion of the door opening 11 on the vehicle outer surface of the vehicle body. A slide door 12 having substantially the same shape as the opening 11 is supported so as to be slidable in the front-rear direction. The sliding door 12 moves rearward from a fully closed position (the position shown in FIGS. 1 and 3) that closes the door opening 11 to fully open the door opening 11 (the rear end of the sliding door 12 is behind the fuel lid 16). Can be slid to the position that reaches

An opening 15 located behind the door opening 11 is formed on the side of the vehicle body, and a fuel lid 16 having substantially the same shape as the opening 15 is provided in the opening 15 so as to be freely opened and closed. Biasing means (not shown) is provided between the fuel lid 16 and the vicinity of the opening 15, and the fuel lid 16 is always urged to rotate toward the fully open position by the biasing force of the biasing means. Further, a lock mechanism (not shown) that holds the fuel lid 16 in the fully closed position is provided in the vicinity of the opening 15 of the vehicle body. When an open switch (not shown) provided near the driver's seat in the vehicle is operated, the lock mechanism is unlocked, so that the fuel lid 16 located at the fully closed position is moved to the fully opened position by the urging force of the urging means. Rotates automatically until Thus, by rotating the fuel lid 16 to the fully open position, fuel can be supplied to a fuel tank (not shown) disposed inside the opening 15.
In the vicinity of the fuel lid 16 of the vehicle body, an open / close state detecting means FS for detecting whether or not the fuel lid 16 is in the fully closed position is provided. The open / close state detection means FS is electrically connected to control means C (see FIG. 1) constituted by a CPU or the like provided in the vehicle body.
The automobile 10 includes a fully-closed detection sensor that detects that the slide door 12 is located at the fully-closed position, and a fully-open detection sensor that detects that the slide door 12 has reached the fully-open position (both illustrated). The full-closed detection sensor and the full-open detection sensor are both electrically connected to the control means C.

The automobile 10 is provided with a drive mechanism for sliding the slide door 12 in the opening direction (rear) and the closing direction (forward). The drive mechanism includes a motor M that can rotate in both forward and reverse directions, and the sliding door 12 slides by the driving force of the motor M. Further, an inner switch 17 for opening and closing the slide door 12 is provided on the inner side surface of the slide door 12 and / or the inner side surface of the vehicle body, and the slide door 12 is opened and closed on the outer side surface of the slide door 12. An outer switch 18 is provided for this purpose. The inner switch 17 and the outer switch 18 are electrically connected to the motor M via the control means C. Further, the motor M can be rotated by a wireless remote controller 19 (see FIG. 1) capable of operating the control means C wirelessly.
Thus, the sliding door 12 can be opened and closed using the driving force of the motor M, but can also be slid in the opening and closing direction by manual operation.

  As shown in FIG. 2, a capacitive non-contact sensor S1 electrically connected to the control means C is fixed to the entire rear end surface (opening side end surface) of the slide door 12 (the entire rear surface is detected). Surface S1a). The capacitance type non-contact sensor S1 is a non-contact type sensor using electric power supplied from the control means C, and is separated from the capacitance type non-contact sensor S1 (contacts the capacitance type non-contact sensor S1). Can be detected, but by reducing the sensing sensitivity under the control of the control means C, the contact mode that senses only the direct contact with the sensing surface S1a of the capacitive non-contact sensor S1 is achieved. It is also possible to use by switching.

Next, the operation of this embodiment will be described with reference to the flowcharts of FIGS.
First, the control means C determines whether or not the fuel lid 16 is open based on the detection result of the open / close state detection means FS (step 1). When it is determined that the fuel lid 16 is in the open state, the motor M is rotated by operating any one of the inner switch 17, the outer switch 18, and the wireless remote controller 19 (step 2). The direction detecting means C determines whether the slide door 12 is sliding in the opening direction based on the rotation direction of the motor M. If the control means C determines in step 3 that the slide door 12 is sliding in the opening direction, the control means (sensor sensitivity adjustment means) C detects the sensitivity of the capacitive non-contact sensor S1 (the presence of an obstacle). Is increased to a high-sensitivity non-contact mode (the amount of electric power supplied to the capacitive non-contact sensor S1 is increased) (step 4).
Next, in step 5 of the subroutine 1, the control means C determines whether or not the slide door 12 has reached the fully open position using the detection result of the fully open detection sensor. If it is determined in step 5 that the sliding door 12 has not reached the fully open position, in step 6, the control means C determines whether or not the detection result of the capacitive non-contact sensor S1 exceeds a threshold value. For example, when the distance between the sensing surface S1a of the capacitive non-contact sensor S1 fixed to the rear end surface of the sliding door 12 and the fuel lid 16 in the open state or the passenger standing immediately after the sliding door 12 is closer than a predetermined distance In step 6, the control means C determines that the detection result of the capacitive non-contact sensor S1 has exceeded the threshold value. If it is determined that the threshold value has been exceeded, the control means C reverses the motor (reverse drive means) M and slides the sliding door 12 in the closing direction to the specified position (step 7). Stop (step 8).
In step 6, the detection result of the capacitive non-contact sensor S1 by the control means C does not exceed the threshold (the sensing surface S1a of the capacitive non-contact sensor S1 and the fuel lid 16 or an obstacle such as a passenger) If it is determined that the distance has not reached the predetermined distance), the sliding door 12 continues to slide in the opening direction (step 9), and in step 5, the control means C again determines whether the sliding door 12 has reached the fully opened position. Determine whether.
If it is determined in step 1 that the fuel lid 16 is in the open state, the slide door 12 cannot slide until it comes into contact with the fuel lid 16 due to the action of the capacitance non-contact sensor S1 as described above. Therefore, when the fuel lid 16 is in the open state, it is determined in step 5 of the subroutine 1 that the slide door 12 has reached the fully open position (position where the rear end of the slide door 12 reaches the rear of the fuel lid 16). Absent.

On the other hand, when the slide door 12 is in the open state, if the control means C determines in step 3 that the slide door 12 is sliding in the closing direction based on the rotation direction of the motor M, the control means C detects the capacitance. The sensing sensitivity of the non-contact sensor S1 is lowered (the amount of power supplied to the non-contact capacitive sensor S1 is lowered), and the capacitive non-contact sensor S1 is switched to the contact mode (step 10).
Next, in step 11 of subroutine 2, the control means C determines whether or not the slide door 12 has reached the fully closed position using the detection result of the fully closed detection sensor. If the control means C determines in step 11 that the slide door 12 has reached the fully closed position, the control means C stops the motor M (step 8).
On the other hand, if it is determined in step 11 that the sliding door 12 has not reached the fully closed position, in step 12, the control means C determines whether or not the detection result of the capacitive non-contact sensor S1 exceeds a threshold value. . For example, as shown in FIG. 4, when a passenger's clothing is sandwiched between the rear end portion of the sliding door 12 and the facing surface of the door opening 11 in a state where the sliding door 12 is located near the fully closed position (the clothing is electrostatic capacitance). In step 12, the control means C determines that the detection result of the capacitance type non-contact sensor S1 has exceeded the threshold value. Then, the control means C reversely rotates the motor M (rotates in the forward direction) to slide the slide door 12 in the opening direction to the specified position (step 13), and stops the motor M when the specified position is reached (step 13). 8).
In step 12, the detection result of the capacitance non-contact sensor S1 by the control means C does not exceed the threshold value (an obstacle such as clothes is not in contact with the sensing surface S1 of the capacitance non-contact sensor S1). ), The sliding door 12 continues to slide in the closing direction (step 14), and in step 11, the control means C determines again whether or not the sliding door 12 has reached the fully closed position.

Next, an operation when the control means C determines in step 1 that the fuel lid 16 is not in the open state will be described.
In this case, in step 15, the control means C lowers the sensing sensitivity of the capacitive non-contact sensor S1 and switches the capacitive non-contact sensor S1 to the contact mode. In this state, when the motor M is rotated by operating any one of the inner switch 17, the outer switch 18, and the wireless remote controller 19 (step 16), the control means C in step 17 causes the sliding door based on the rotation direction of the motor M. It is determined whether 12 is sliding in the opening direction. If the control means C determines in step 17 that the slide door 12 is sliding in the opening direction, in step 5 of the subroutine 1, the control means C uses the detection result of the full open detection sensor to open the slide door 12 fully open. It is determined whether or not the position has been reached. If it is determined in step 5 that the slide door 12 has reached the fully open position, the control means C stops the motor M (step 8).
On the other hand, if it is determined in step 5 that the sliding door 12 has not reached the fully open position, the control means C stops the motor M in step 8 through step 6 and step 7 (or step 9) as in the case described above.
On the other hand, if the control means C determines in step 17 that the slide door 12 is sliding in the closing direction, the control means C stops the motor M in step 8 via the subroutine 2 (step 8).

Thus, in this embodiment, since the sensing by the capacitive non-contact sensor S1 is enabled regardless of whether the fuel lid 16 is in the open state or the closed state, it is determined whether or not the fuel lid 16 is open. Regardless, the sliding operation can be prevented from continuing while the sliding door 12 is in contact with the obstacle.
In particular, when the fuel lid 16 is in the open state and the slide door 12 is sliding in the open direction, the sensing sensitivity of the capacitive non-contact sensor S1 is increased (in the non-contact mode), so that the open state is established. It is possible to reliably prevent the sliding door 12 sliding in the opening direction from contacting a certain fuel lid 16.
Further, when clothes or the like are sandwiched between the slide door 12 and the door opening 11, the sandwiched state is detected by the capacitance non-contact sensor S1, so that the sandwiched state can be quickly eliminated.

Further, in a state where the slide door 12 is not likely to contact the fuel lid 16, that is, in a case where the fuel lid 16 is in a closed state and in a case where the fuel lid 16 is in an open state and the slide door 12 slides in the closing direction. The sensitivity of the capacitive non-contact sensor S1 is lowered to the contact mode. Therefore, when the slide door 12 slides to the fully closed position, the capacitance-type non-contact sensor S1 erroneously detects the opening edge (opposing portion) of the door opening 11, and the sliding door 12 opens the opening edge of the door opening 11. The sliding door 12 is not accidentally slid in the opening direction even though no obstacle (clothing or the like) is sandwiched between the sliding door 12 and the door.
Further, by lowering the sensitivity of the capacitive non-contact sensor S1, energy (electric power) for operating the capacitive non-contact sensor S1 is opened in the fuel lid and the sliding door slides in the opening direction. Since it can suppress compared with the case, energy saving can be achieved.

In the above embodiment, the slide door 12 is slid by the driving force of the motor M. However, the slide door 12 can be manually opened and closed as described above. When the sliding door 12 is manually opened and closed, the motor M is used only in steps 7 and 13.
Further, in this embodiment, when the fuel lid 16 is in the closed state and when the fuel lid 16 is in the open state and the sliding door 12 slides in the closing direction, the sensing sensitivity of the capacitive non-contact sensor S1 is lowered to make contact. Mode. However, in the fully closed state shown in FIG. 3, if the sensing sensitivity is lowered to such an extent that the capacitive non-contact sensor S1 does not sense the facing part on the vehicle body side (for example, the rear edge of the door opening 11), The capacitive non-contact sensor S1 may be used in the non-contact mode.
Furthermore, in this embodiment, since the opening direction of the sliding door 12 is the rear, the capacitive non-contact sensor S1 is provided on the rear end surface of the sliding door 12. However, the opening direction of the sliding door 12 is the front and the fuel lid 16 is opened to the door. 11 is provided in front of the slide door 12 with a capacitance non-contact sensor S1.
Further, in the present embodiment, the capacitance type non-contact sensor S1 is provided on the entire rear end surface (end surface side end surface) of the slide door 12, but a part of the rear end surface of the slide door 12 (with the same height as the fuel lid 16). The capacitance non-contact sensor S1 may be provided only in the portion (the position where the fuel lid 16 can be detected is necessarily included).

Further, separately from the drive mechanism (motor M), the control is performed by the control means C which is driven when the slide door 12 reaches the vicinity of the predetermined fully closed position and forcibly moves the slide door 12 to the fully closed position. A closer mechanism (not shown) may be provided. In this case, when the slide door 12 reaches the vicinity of the fully closed position, the control means C stops the motor M and rotates the closer motor of the closer mechanism, and the sliding door 12 is fully closed by the rotational force of the closer motor. Move to position.
In this case, when the control means C determines that the detection result of the capacitance-type non-contact sensor S1 exceeds the threshold value in step 12 when the slide door 12 is positioned near the fully closed position, The control means C cancels without operating the closer mechanism (closer motor), rotates the motor M forward, and slides the slide door 12 in the opening direction.

  In this embodiment, the capacitive non-contact sensor S1 is used as the non-contact sensor, but other types of non-contact sensors may be used.
