First Embodiment
With reference to FIG. 1, the opening / closing body control device 100 in the present embodiment will be described. In the present embodiment, the opening / closing body control device 100 is a power window control device PC which is provided in a vehicle and controls driving of a power window PW which the window glass WN slides up and down with respect to the window frame FL of the door. Make up a part of In this case, the opening / closing body is the window glass WN, the opening operation of the opening / closing body is an operation of sliding downward, and the closing operation is an operation of sliding upward, and in both operations, the window glass WN Movement in a direction substantially perpendicular to the thickness direction of the

  The opening and closing body is not limited to this, and may be a power slide door provided on the side of the vehicle. In this case, the opening operation or closing operation (opening and closing operation) is in the front-rear direction (substantially horizontal direction) of the vehicle. It is movement, and movement in a direction substantially perpendicular to the thickness direction of the power slide door. In addition, the opening and closing body may be a power tail gate, and in this case, the opening and closing operation is a movement in the vertical direction (substantially vertical direction) of the vehicle and in a direction substantially horizontal to the thickness direction of the power tail gate. It is a moving motion. The opening and closing member may be a shutter provided outdoors, in which case the opening operation is an operation of sliding upward, the closing operation is an operation of sliding downward, and both of the operations are shutters Movement in a direction substantially perpendicular to the thickness direction of the

  The power window control device PC generates pulses from operations such as an actuator AC for opening and closing the window glass WN, a power window opening and closing mechanism WM directly driven by the actuator AC to open and close the window glass WN in the vertical direction, and rotation of the actuator AC. The pulse generator PG to be generated, the position sensor SN for detecting the vertical position of the window glass WN, the power window operation unit SW operated by the user for moving the window glass WN in the vertical direction, and the opening / closing control And an apparatus 100. The actuator AC is configured to be capable of normal and reverse rotation by being supplied with electric power through the drive control unit 10 described later. For example, in the case of forward rotation, the window glass WN is turned downward, reversely At the time of rotation, the window glass WN is driven upward.

  The power window opening / closing mechanism WM is disposed inside the door below the window glass WN, and opens / closes the window glass WN by the operation of the actuator AC. The power window opening / closing mechanism WM includes a plate for supporting the lower end of the window glass WN, a guide rail for defining the movement direction of the window glass WN, a slider coupled to the plate and guided by sliding on the guide rail, a slider and an actuator The main components are wires connected to the AC output shaft.

  The pulse generator PG is a device for outputting a pulse signal synchronized with an operation such as rotation of the actuator AC to the opening / closing body control device 100. For example, the pulse generator PG is configured to detect a magnetic change of a magnet that rotates with the output shaft of the actuator AC. Therefore, the pulse generator PG outputs a pulse signal for each predetermined movement amount of the window glass WN or for each predetermined rotation angle of the actuator AC. The position sensor SN may be disposed inside the door below the window glass WN and may detect the vertical position of the window glass WN. The pulse generator PG can also output a signal corresponding to the moving speed of the window glass WN proportional to the rotational speed of the actuator AC, and if the vertical position of the window glass WN is known from this signal, the position The sensor SN may not be present. The power window operation unit SW is a so-called operation switch for moving the window glass WN in the vertical direction. When the power window operation unit SW is operated to move the window glass WN upward or downward, the operation state is transmitted to the open / close controller 100.

  The open / close controller 100 controls the drive control unit 10 that controls the drive of the actuator AC that opens and closes the window glass WN, the position detection unit 20 that detects the open and close position of the window glass WN, and the window detected by the position detection unit 20 And a fixation determination unit that determines that the window glass WN is in a fixed state based on one or both of the position of the glass WN and the driven physical quantity of the actuator AC detected by the physical quantity detection unit 30.

  The position detection unit 20 detects the vertical position of the window glass WN detected by the position sensor SN, and whether the upper end of the window glass WN is in contact with the window frame FL and is completely closed, the upper end of the window glass WN Detects whether or not the door is fully open, such as below the upper end of the door, or at any position between them. In the present embodiment, the position detection unit 20 detects the position of the window glass WN based on the position detected by the position sensor SN, but the vertical position of the window glass WN is determined by the signal of the pulse generator PG. In this case, the position of the window glass WN may be detected based on the signal of the pulse generator PG.

  The physical quantity detection unit 30 detects the physical quantity of the actuator AC, for example, movement amount / rotation angle, movement speed / rotation speed, current, etc., based on the pulse signal output from the pulse generator PG. For example, the physical quantity detected by the physical quantity detection unit 30 is equal to the movement amount of the window glass WN moved in the vertical direction when the vertical position of the window glass WN is determined by the pulse signal.

  In the fixation determination unit 40, although the drive control unit 10 drives the actuator AC to move the window glass WN downward, the upper end of the window glass WN abuts the window frame FL with the position detection unit 20 completely. When it is detected that the window is closed, it may be determined that the window glass WN is fixed to the window frame FL. Further, in the case where the physical quantity detected by the physical quantity detection unit 30 determines the vertical position of the window glass WN by the pulse signal, the drive control unit 10 drives the actuator AC to move the window glass WN downward. If there is no change in the physical quantity of movement or rotation angle detected by the physical quantity detection unit 30 despite that, the fixation determination unit 40 may determine that the window glass WN is fixed to the window frame FL . In addition, even though the drive control unit 10 drives the actuator AC to move the window glass WN downward, if the physical amount of the movement speed or the rotation speed detected by the physical quantity detection unit 30 is substantially zero, sticking occurs. The determination unit 40 may determine that the window glass WN is fixed to the window frame FL. In addition, the position detection unit 20 is in a state in which the upper end of the window glass WN abuts on the window frame FL and is completely closed even though there is a change in the physical quantity of movement and rotation angle detected by the physical quantity detection unit 30 When it is detected, the adhesion determination unit 40 may determine that the window glass WN is adhered to the window frame FL. In addition, when it is detected that the physical quantity of the current detected by the physical quantity detection unit 30 has passed for a predetermined value or more and a predetermined time or more has elapsed, the fixation determination unit 40 determines that the window glass WN is adhered to the window frame FL. You may

  When the adhesion determination unit 40 determines that the window glass WN is in the adhered state, the drive control unit 10 drives the actuator AC as shown in FIG. 2 (B). Before describing this figure, control of the drive of the actuator AC according to the prior art will be described with reference to FIG. 2 (A). In the prior art, when the power window operation unit SW is opened in the closed state of the window glass WN, the DOWN output for driving the window glass WN downward, ie, for opening the window WN continues to be issued. If the DOWN output is continued while the window glass WN is fixed due to freezing or the like, current may continue to flow to the actuator AC, but the actuator may be damaged due to heat generation or the like because it does not move.

  On the other hand, as shown in FIG. 2 (B), the drive control unit 10 according to the present invention once issues a DOWN output when the power window operation unit SW is opened in a state where the window glass WN is closed. As described above, when the adhesion determination unit 40 determines that the window glass WN is in the adhered state, the DOWN output is stopped, and the UP output for driving the window glass WN upward, that is, for closing the window W Then, the DOWN output and the UP output are alternately repeated (inching) a predetermined number of times (two times in the figure). The predetermined number of times is a necessary and sufficient number of times that the window glass WN can be detached even if the window glass WN is fixed to the window frame FL, and is appropriately determined, for example, in a range of several times to over ten times. Further, the time of each of the DOWN output and the UP output alternately repeated is appropriately determined in the range of, for example, several Hz to several tens Hz. After alternately repeating the DOWN output and the UP output a predetermined number of times, the drive control unit 10 continues to issue the DOWN output as appropriate.

  The drive control unit 10 performs the operation to repeat alternately in this manner when the position detection unit 20 detects that the open / close position of the window glass WN is in a predetermined position section. Here, the predetermined position section is between the position where the upper end of the window glass WN is in contact with the window frame FL and is completely closed and in contact with the window frame FL. In this position section, the window glass WN may be fixed due to freezing. For example, as shown in FIG. 1, the window WN is fully open from the fully closed position where the upper end of the window WN abuts the window frame FL and the upper end of the window WN is below the upper end of the door. With respect to the movement range Z, the predetermined position section S is a part thereof and contacts the window frame FL which is not completely closed but may freeze and stick from a completely closed position. Between the positions you are doing.

  As described above, in the case where the position detection unit 20 detects that the open / close position of the window glass WN is in the predetermined position section, and the adhesion determination unit 40 determines that the window glass WN is in the adhered state, drive control is performed. The unit 10 controls the drive of the actuator AC to perform the closing operation and the opening operation of the window glass WN a predetermined number of times. The fixed state can be removed by repeating the closing operation and the opening operation a predetermined number of times, whereby the window glass WN becomes frozen and can not be driven without requiring expensive parts. Can be controlled to drive the

  The open / close member in the present embodiment is the window glass WN of the power window PW, and the opening operation and the closing operation are operations moving in a direction substantially perpendicular to the thickness direction of the window glass WN. According to this, it is possible to drive the window glass WN even if the sliding and moving window glass WN becomes frozen and does not move.

  A control method of the opening / closing body control device 100 will be described with reference to the flowchart of FIG. 3. In the flowchart, S represents a step. In S100, the opening / closing body control device 100 detects the state of the operation transmitted from the power window operation unit SW. When the power window operation unit SW is operated to drive the window glass WN downward, the drive control unit 10 outputs the DOWN output to drive the actuator AC to move the window glass WN downward at S102. Do. If no operation is performed on the power window operation unit SW, nothing is output and the state of the power window operation unit SW is continuously checked.

  For example, when the position detection unit 20 detects that the open / close position of the window glass WN is in the predetermined position section S in S104, the fixation determination unit 40 starts to flow the current detected by the physical quantity detection unit 30 or more. It is checked whether it is detected that a predetermined time has passed or not. When detecting that the current detected by the physical quantity detection unit 30 has passed a predetermined value or more has passed for a predetermined time or more, the fixation determination unit 40 determines that the window glass WN is fixed to the window frame FL, and the drive control unit 10 outputs UP to drive the actuator AC to move the window glass WN upward at S106. The drive control unit 10 continues to output UP for a predetermined time in S108. After continuing to output UP for a predetermined time, the drive control unit 10 outputs DOWN to drive the actuator AC so as to move the window glass WN downward in S110. The drive control unit 10 continues to output DOWN for a predetermined time in S112.

  In S114, the drive control unit 10 adds one to the inching number for the purpose of checking the number of repetitions of the UP output and the DOWN output (inching number). In S116, the drive control unit 10 checks whether or not the number of times of inching has reached a predetermined number of times sufficient to allow removal of the window glass WN even if the window glass WN is fixed to the window frame FL. Do. If not reached, the drive control unit 10 returns to S104 and checks whether or not to detect that a predetermined time or more has elapsed. If reached, the DOWN output is stopped in S118, and the inching number is initialized in S120. (To zero). In this case, the fixed state can not be released even if the closing operation and the opening operation are repeated a predetermined number of times. As described above, when the window glass WN can not be removed from the fixed and fixed state even after inching a predetermined number of times, the actuator AC is driven for a long time by stopping the DOWN output to the actuator AC. It can be prevented from being damaged.

  On the other hand, when the number of inchings does not exceed the predetermined number in S116, the process returns to S104. In this case, the adhesion determination unit does not elapse for a predetermined time or more after the current detected by the physical quantity detection unit 30 starts to flow for a predetermined value or more. 40 determines that the window glass WN is not fixed to the window frame FL, and the drive control unit 10 checks in S128 whether or not the DOWN stop condition is satisfied, and continues to issue the DOWN output until it is satisfied. The DOWN stop condition is that the window glass WN has moved to the full opening movement range Z or more, that the opening operation in the power window operation unit SW is turned off, and the current value in the actuator AC detected by the physical quantity detection unit 30 is It is any one of being more than predetermined value. If none of these conditions is satisfied, the opening / closing body control device 100 returns to S100 and detects the state of the power window operation unit SW. In addition, when any one of these conditions is satisfied, the drive control unit 10 stops the DOWN output in S130.

  The open / close controller 100 detects the state of the power window operation unit SW in S100, and when the power window operation unit SW is operated to drive the window glass WN upward, in S122, the window glass WN Is output to drive the actuator AC so as to move upward. The drive control unit 10 checks whether or not the UP stop condition is satisfied in S124, and continues to issue the UP output until the condition is satisfied. In the UP stop condition, the window glass WN is moved to the completely closed state, the closing operation in the power window operation unit SW is turned off, and the current value in the actuator AC detected by the physical quantity detection unit 30 Is either greater than or equal to a predetermined value. If none of these conditions is satisfied, the opening / closing body control device 100 returns to S100 and detects the state of the power window operation unit SW. In addition, when any one of these conditions is satisfied, the drive control unit 10 stops the UP output in S126.

  The method described above is an open / close control method for controlling the opening / closing operation of the opening / closing body such as the window glass WN, which detects whether the opening / closing position of the opening / closing body is a predetermined position section, If it is determined that the open / close position of the open / close body is in the predetermined position section and it is determined that the open / close body is in the fixed state, the open / close body is closed and opened a predetermined number of times It is an opening / closing body control method to control. By repeating the opening and closing operations of the opening and closing body in this manner, the opening and closing body is controlled such that the opening and closing body can be driven even if the opening and closing body becomes frozen and can not be driven without requiring expensive parts. A control method can be provided.
