Field of the Invention The present invention relates to an automatic opening / closing device for a vehicle sliding door that opens and closes a sliding door attached to a side surface of a vehicle body such as an automobile by a driving source such as a motor, and more particularly to a sliding door that is driven in a closing direction. The present invention relates to an automatic opening / closing device for a sliding door for a vehicle that can be tightened.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, an automatic opening / closing device for a sliding door for a vehicle is known in which a sliding door is attached to a side surface of a vehicle body such as an automobile so as to be movable in the front-rear direction, and the sliding door is opened and closed by a driving source such as a motor. .
[0003]
This device activates the drive source with the control device installed in the car by operating the sliding door opening / closing operator provided near the driver's seat and the rear seat, or by operating the wireless remote control from outside the car. Further, the sliding door is driven to open and close by transmitting the power of the drive source to the sliding door opening / closing mechanism with the electromagnetic clutch turned on (connected).
[0004]
In addition, when this device moves the sliding door in the closing direction, the slide door control device controls from the fully open position to the half latch position, and the closure control device controls from the half latch position to the full latch position. It is configured to tighten up to.
[0005]
In this case, the slide door control device is generally installed on the vehicle body side, and the closure control device is installed in the slide door. When each control device detects that the slide door has passed the half latch position, the slide door control device stops driving, and the closure control device starts driving.
[0006]
[Problems to be solved by the invention]
By the way, as a method of detecting that the slide door has passed the half latch position, there is a method of providing a switch (half latch switch) on the door lock pole. This method can accurately detect the half latch position of the sliding door, but cannot detect the side close to the full latch position between the half latch position and the full latch position.
[0007]
In addition, if the sliding door rapidly moves in the closing direction, the sliding door control device may not be able to detect whether the half latch switch is turned on, or even if the sliding door control device detects that the half latch switch is turned on, the closure control device May not be detected, and in any case, the closure control device does not operate.
[0008]
When operated manually, the sliding door returns slightly in the opening direction due to the reaction force of the seal rubber provided at the door opening, but when driven by a drive source such as a motor, the friction of the drive mechanism is caused by the reaction force of the seal rubber. Since is larger, the sliding door may not return to the opening direction, and the half latch switch may not be turned on again. For this reason, the closure control device does not operate, and there arises a disadvantage that the sliding door remains stopped at the half latch position.
[0009]
The present invention has been made to solve such a conventional problem, and when the sliding door is driven in the closing direction using a driving source, the sliding door control device and the closure control device turn on the half latch switch.

[0023]
The sliding door drive device 12 includes a drive pulley 12a and a reversing pulley 12b. A cable member 12c is wound between the drive pulley 12a and the moving member 12d is fixed to the cable member 12c, and the moving member 12d and the sliding door 2 are hinged to each other. The connection is made through 31. The drive pulley 12a, the reversing pulley 12b, the cable member 12c, and the moving member 12d constitute a slide door opening / closing mechanism.
[0024]
The drive pulley 12a is connected to an open / close motor 12f which is a drive source via an electromagnetic clutch 12e. The electromagnetic clutch 12e is configured such that the transmission maintenance force is controlled by the sliding door control device 11.
[0025]
The opening / closing motor 12f is rotationally driven in the opening direction or the closing direction under the control of the sliding door control device 11. When the electromagnetic clutch 12e is turned on (connected), the drive pulley 12a is rotationally driven in the same direction as the opening / closing motor 12f, and moves the cable member 12c in a linear direction between the reverse pulley 12b. As a result, the slide door 2 moves in the front-rear direction.
[0026]
A rotary encoder 12g is linked to the rotary shaft of the drive pulley 12a. The output pulse is input to the pulse signal generator 12h and input to the sliding door control device 11 as two-phase pulse signals φ1 and φ2.
[0027]

Are two-phase pulse signals φ1 and φ2. In this example, the sliding door 2 is driven in the opening direction when the rotating disk RD rotates to the right.
[0029]
Therefore, the sliding door control device 11 can determine the rotational direction of the rotary encoder 12g, that is, the moving direction of the sliding door 2 from the phase relationship between these two signals. That is, if the pulse signal φ2 is at a high level when the pulse signal φ1 rises, it is determined to be in the opening direction (FIG. A), and if it is at a low level, it is determined to be in the closing direction (FIG. B).
[0030]
Further, the slide door control device 11 obtains the position of the slide door 2 by measuring the movement amount of the cable member 12c from the number of pulses of the pulse signals φ1 and φ2. That is, if the number of pulses to the fully open position is counted with the fully closed position of the slide door 2 as an initial value, the counted value represents the position of the moving member 12d, that is, the position of the slide door 2.

[0045]
The closure control unit 33 drives the slide motor 2 between the half-latch position and the full-latch position by driving the closure motor 32 forward or backward from the neutral position, and similarly to the slide door control device 11, the closure motor 32 is driven. The motor control relay for driving the motor, the transistor for controlling the rotational speed, and the like.
[0046]
(Description of operation)
Next, the operation of the present embodiment will be described with reference to the flowchart shown in FIG. First, when a command to drive the sliding door 2 in the closing direction is issued by operating the door closing switch 20 or the like, the control circuit 11a controls the transistor 11c to turn on the electromagnetic clutch 12e (step S1). .
[0047]
Next, the control circuit 11a turns off the switch element TR2, interrupts the current flowing through the relay coil of the motor control relay 11d, and opens the contact switch. At the same time, the switch element TR3 is turned on to pass a current through the relay coil of the motor control relay 11e, and the contact switch is closed to supply power to the other end of the open / close motor 12f. As a result, the opening / closing motor 12f starts to rotate in a direction to drive the slide door 2 in the closing direction (step S2), and the slide door 2 moves in the closing direction.
[0048]
When the slide door 2 passes through the half latch position (step S3), both the connectors 25 and 39 of the power supply connector 5 are coupled, and the control circuit 11a detects that the half latch switch 34 is turned on (step S4).
[0049]
As a result, the control circuit 11a controls the transistor 11c to switch the electromagnetic clutch 12e from on (connected) to off (disconnected), turns off the switch elements TR2 and TR3, and opens the contact switches of the motor control relays 11d and 11e, The opening / closing motor 12f is stopped (step S5). As a result, the connection state between the slide door 2 and the opening / closing motor 12f is cut off.
[0050]
If the control circuit 11a does not detect the ON state of the half latch switch 34 (step S4), the driving load increases to drive the sliding door 2 in the closing direction beyond the half latch, and the pinching detection function is activated. Then, the motor control relays 11d and 11e are switched to reverse the opening / closing motor 12f in the opening direction, and the transistor 11f is controlled to drive at a low voltage (step S6). When the slide door 2 comes to the half latch position and the half latch switch 34 is turned on (step S7), the process proceeds to step S5. The case where the control circuit 11a does not detect the ON state of the half latch switch 34 means that, for example, the side closer to the full latch has a smaller amount of operation of the pole, and the operation stroke of the half latch switch 34 cannot be obtained. When the door 2 is suddenly closed, the return operation of the pole of the half-latch switch 34 cannot catch up and the half-latch switch 34 does not operate. Alternatively, the open / close motor 12f of the slide door control device 11 is driven to open the slide door 2. For example, a case where a pinching phenomenon occurs during the closing of the door and the slide door 2 stops in the middle of the closing operation.
[0051]
By driving at a low voltage, the motor lock torque is smaller than when driving at a normal voltage, so the burden on the mechanism can be reduced, and the speed when the slide door 2 is returned to the opening direction is low, so the slide The behavior of the door 2 can be made smooth.
[0052]
Whether the open / close motor 12f operates at a normal voltage or a low voltage at the time of reversing in the opening direction is as follows. The position of the slide door 2 can be detected from the pulse signals φ1 and φ2 of the rotary encoder 12g.
[0053]
(1) Originally, when the position of the sliding door 2 is closed from the position (range) where the ON of the half latch switch 34 is detected and the pinching detection function is activated, the ON of the half latch switch 34 cannot be detected and the half is detected. It is determined that the latch state has been reached, and the operating voltage when reversing in the opening direction is set to a low voltage.
[0054]
(2) If the position of the sliding door 2 is open from the position (range) where the half latch switch 34 is detected to be on and the pinching detection function is activated, it is determined that pinching has actually occurred, The operating voltage at the time of inversion is the normal operating voltage.
[0055]
Next, the control circuit 11a turns on the switch element TR1, causes a current to flow through the relay coil of the closure power supply relay 11g, closes the contact switch, and supplies power to the closure control unit 33 (step S8).
[0056]
Next, when the control circuit 11a detects the closure current flowing through the resistor R within the predetermined time T1 (step S9), the closure control unit 33 detects that the half latch switch 34 is turned on and determines that the closure motor 32 has been driven. The closure motor 32 rotates forward to tighten the slide door 2 and then reverses to return to the neutral position and stops operating (step S10).
[0057]
When the control circuit 11a detects that the closure current does not flow through the resistor R for a certain time T3 (step S11), the control circuit 11a determines that the tightening of the slide door 2 by the closure motor 32 is finished, and turns off the closure power supply relay 11g. Then, power supply to the closure control unit 33 is stopped (step S12), and the process is terminated.
[0058]
If the control circuit 11a fails to detect the closure current within the predetermined time T1 (step S9), the control circuit 11a determines that the half-latch switch 34 cannot be detected, and drives the transistor 11c to drive the electromagnetic clutch. 12e is turned on (connected). Further, the motor control relays 11d and 11e are controlled to reverse the opening / closing motor 12f in the opening direction, and the slide door 2 is driven in the opening direction (step S13).
[0059]
In this case, it is preferable to control the transistor 11f to drive the open / close motor 12f at a low voltage and move the slide door 2 at a low speed. This is because the sliding door 2 is moved in the opening direction in order to return the sliding door 2 to the ON region of the half latch switch 34, and the reaction force of the seal rubber is sufficient to compensate for the lack.
[0060]
Low-voltage drive has a smaller motor lock torque than normal drive where the drive power is applied as it is, so the burden on the mechanism can be reduced, and the speed when the sliding door 2 is returned to the opening direction is low, and the behavior is low. It can be smooth.
[0061]
As another method for lowering the opening driving force from the driving force during the normal opening operation, the electromagnetic clutch 12e may be driven at a low voltage by controlling the transistor 11c. As a result, the electromagnetic clutch 12e is in a half-clutch state, and the opening driving force is reduced, so that the burden on the mechanism portion can be reduced.
[0062]
Next, when the control circuit 11a detects a closure current within a predetermined time T2 thereafter (step S14), the control circuit 11a determines that the half latch switch 34 is turned on and drives the closure motor 32, and the transistor 11c is controlled to switch off the electromagnetic clutch 12e, the motor control relays 11d and 11e are controlled to stop the open / close motor 12f (step S15), and the process proceeds to step S10 described above.
[0063]
If the control circuit 11a does not detect the closure current within the predetermined time T2 (step S14), the control circuit 11a determines that there is a failure in the closure system, and controls the transistor 11c to switch off the electromagnetic clutch 12e to control the motor. The relay 11d, 11e is controlled to stop the open / close motor 12f, the closure power supply relay 11g is turned off to stop the power supply to the closure control unit 33, a failure alarm is issued, and the process is terminated (step S16).
[0064]
Next, the operation of the present embodiment will be described with reference to the waveform diagrams shown in FIGS. FIG. 6 is a waveform diagram when the closure control unit 33 normally detects the ON state of the half latch switch 34 and drives the closure motor 32 within a predetermined time T1.
[0065]
In this figure, (a) shows the on / off state of the half latch switch 34, (b) shows the on / off state of the neutral switch 35, and (c) shows the on / off state of the closure power supply relay 11g. (D) shows the respective states of the closing / stopping / opening operation of the opening / closing motor 12f, (e) shows the respective forward / stop / reverse states of the closure motor 32, and (f) shows the closure current. Is shown.
[0066]
First, when the half latch switch 34 is turned on for a certain period of time at time t1, this is detected by the control circuit 11a, and the closure power supply relay 11g is turned on with a slight delay, and the open / close motor 12f is changed from the closed operation to the stopped state. At this time, the electromagnetic relay 12e is also turned off.
[0067]
Thereafter, when the closure motor 32 starts normal rotation from a stopped state within a predetermined time T1, a closure current starts to flow. Further, since the closure motor 32 has started normal rotation, the neutral switch 35 that is turned off is turned on in the standby state (neutral state).
[0068]
When the sliding door 2 reaches the full latch position at the time t2, the half latch switch 34 is turned on again, and the closure motor 32 is stopped with a slight delay, and then reverse rotation is started. The magnitude of the closure current changes accordingly.
[0069]
When the closure motor 32 returns to the vicinity of the standby position, the neutral switch is turned off at a time t3, and the closure motor 32 stops with a slight delay, and the closure current becomes zero. The closure power supply relay 11g is turned off at a time t4 after a certain time T3 from this time, and the power supply to the closure control unit 33 is stopped.
[0070]
FIG. 7 is a waveform diagram when the closure control unit 33 cannot detect the ON state of the half latch switch 34. FIGS. 6A to 6F are the same as FIGS. 6A to 6F.
[0071]
First, when the half latch switch 34 is turned on at the time point ta, the control circuit 11a detects this, delays a little, turns on the closure power supply relay 11g, and switches the open / close motor 12f from the closed operation to the stopped state. At this time, the electromagnetic relay 12e is also turned off.
[0072]
If the closure current does not flow after a certain time T1 from this time, the control unit 11a determines that the closure control unit 33 has not detected that the half latch switch 34 is turned on, and turns on the electromagnetic clutch 12e at time tb. Then, the motor control relays 11d and 11e are controlled to reverse the opening / closing motor 12f in the opening direction, and the slide door 2 is driven in the opening direction.
[0073]
When the sliding door 2 moves in the opening direction to turn on the half latch switch 34 and reaches the half latch position at the time tc, the closure control unit 33 detects this and delays the closure motor 32 from the stopped state. Turn. As a result, a closure current starts to flow, the control circuit 11a detects the closure current, and the switching motor 12f is stopped with a slight delay.
[0074]
The subsequent operation is the same as the operation from time t1 to time t4 in FIG. 6, with time tc corresponding to time t1, time td corresponding to time t2, time te corresponding to time t3, and time tf corresponding to time t4. If the closure current does not flow within a certain time T2 from the time tb, it is determined that there is a failure in the closure system.
[0075]
【The invention's effect】
According to the present invention, when the sliding door control device does not detect the operation of the half latch switch, or when the sliding door control device detects the operation of the half latch switch, but the closure control unit does not operate, the sliding door Is forced to reverse in the opening direction, so that the sliding door control device and the closure control unit reliably detect the operation of the half latch switch, so the closure control unit operates the closure motor to fully latch the sliding door. It can be securely tightened to the position.
[0076]
In addition, according to the present invention, when the sliding door is forcibly reversed in the opening direction, the driving force is reduced, so that the burden on the mechanism portion is reduced as compared with the normal driving in which the driving power is applied as it is. And the behavior when the sliding door is returned to the opening direction can be made smooth.
