Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a highly safe window opening / closing control device.

[0002]

[Prior art]

 The electrically operated window has a window opening / closing mechanism that opens and closes the window, a drive motor that drives the window opening and closing mechanism, and a control unit that controls forward and reverse rotation and stop of the drive motor. A window opening / closing switch that outputs a window opening / closing signal to the control unit is attached.

When raising and lowering such an electric window, it is necessary to stop the operation of the drive motor at the rising end or the falling end of the window. Therefore, conventionally, the operation of the drive motor is controlled based on the signals from the touch limit switches that detect the raising and lowering end positions of the window, for example, the one proposed in Japanese Patent Laid-Open No. 2-127125, and the window raising and lowering. The lock current that flows when the rotation of the drive motor is stopped is detected based on the steady current (ripple current) that flows in the drive motor, and the drive motor is stopped when the lock current flows to the drive motor. Those that have been put into practical use have been put to practical use.

In the drive motor that is stopped by the lock current, the mechanical restraining force of the window opening / closing mechanism works at the rising or falling end of the window, so that the amount of electricity supplied to the driving motor rapidly increases. Is used to stop the drive motor as the amount of electricity to the drive motor rapidly increases.

[0005]

[Problems to be solved by the device]

 In the conventional window opening / closing control device proposed in Japanese Patent Publication No. 2-127125, which controls the operation of the drive motor based on the detection signal from the touch limit switch, the touch limit switch may be improperly installed or aged. There is a possibility that it will be displaced from the specified position due to physical loosening. In such a case, the drive motor becomes overloaded and an overcurrent also flows through the control circuit of the drive motor. However, the power consumption drastically increases, and mechanical interference occurs due to the overrun of the window, which may result in damage to the sealing material and mechanical parts.

In addition, the mechanical restraint force of the window opening / closing mechanism at the rising end or the falling end of the window is used to stop the drive motor in response to a sudden increase in the amount of electricity supplied to the drive motor. In the opening / closing control device, the rotation of this drive motor does not stop unless a lock current flows through the drive motor.Therefore, rusting or freezing of the moving part of the window opening / closing mechanism that opens and closes the window, or foreign matter in this moving part. The drive motor may not stop for a while even if a part of the human body or something is caught in the opening of the window when it gets caught, etc. Some improvement is desirable in consideration of safety. .

[0007]

[Means for Solving the Problems]

 A window opening / closing control device according to the present invention includes a window that is openable / closable, a window opening / closing mechanism that opens / closes the window, a drive motor that can drive the window opening / closing mechanism in a forward / reverse direction, and The control unit includes a control unit for controlling the stop, and the control unit detects a current value flowing through the drive motor, and a time from the detection of the current value until the drive motor is stopped. Drive motor stop time setting means set in a plurality of stages according to the value.

In this case, the current value, which is set by the drive motor stop time setting means until the drive motor is stopped, is larger than the steady-state current flowing in the drive motor and also flows in the drive motor. It is effective that it is smaller than the lock current. Further, it is desirable to set the time until the drive motor is stopped to be shorter as the current value is larger.

[0009]

[Action]

 According to the present invention, the current value flowing in the drive motor is detected by the current detecting means when the drive motor is in operation, and based on the current value, based on the stop time of the drive motor set by the drive motor stop time setting means. The control unit switches the stop time of the drive motor.

That is, when the current value is a value corresponding to the lock current, the drive motor is immediately stopped. If this current value is smaller than the lock current and larger than the steady current, the time from detecting this current value to stopping the drive motor is set to be shorter as the current value increases. To do. As a result, the drive motor is stopped appropriately according to the load.

The pair of left and right rear pillars 12 and the rear roof rail 13 are integrally joined together to form a so-called roll bar. Further, between the front end of the rear roof rail 13 and the upper end of the windshield 14, front and rear end portions of the roof top 15 are detachably attached via a locking device (not shown). The roof top 15 of this embodiment has a structure that can be divided in the width direction of the vehicle body, and can be stored in a divided state in a rear trunk 17 (see FIG. 11) that is opened and closed by a trunk lid 16 at the rear of the vehicle body. It is like this.

A pair of left and right rear floor side members 19 each having a groove-shaped cross section are integrally joined to the left and right ends of the rear floor pan 18 to which the lower ends of the rear quarter panels 11 are joined, respectively. The lower ends of a pair of left and right rear seatbelt towers 20 each having a hollow columnar shape are joined to the member 19.

2 to 7 and FIG. 8 showing the outer appearance of the rear window opening / closing device in this embodiment, FIG. 9 showing its expanded cross-sectional shape, FIG. 10 showing the cross-sectional structure of the upper end of the rear window, and FIG. As shown in FIG. 11 showing a sectional structure, and FIG. 12 showing a side view of the rear part of the vehicle body in this embodiment when the rear window 37 is in a half-opened state and a fully-opened state, a bulkhead partitioning the front end side of the rear trunk 17 is shown. A window housing 39 for housing a rear window 37 is formed between the head 38 (see FIG. 11) and a seat back of a rear seat (not shown), and the bulk head 38 has a window housing 39 at the upper end thereof. A waist molding 40 that curves along the lower end is attached.

Rear ends of a pair of left and right sash connecting arms 43 projecting forward are integrally connected to the front side of the lower end of the window sash 42 that constitutes the main part of the rear window 37 with the window glass 41. The front end portions of the pair of left and right sash connecting arms 43 located in the gap formed between the rear quarter panel 11 and the rear side panel 21 are integrated with the lower end portion of the rear pillar 12 of the rear quarter panel 11. The pair of left and right window mount brackets 44 fixed to the left and right sides are rotatably pivoted via pins 45, respectively. That is, the rear window 37 can be opened and closed around these pins 45.

Further, the window mount bracket 44 has a tip portion abutting against the sash connecting arm 43 via a switch bracket 46 so that the rear window 37 is in a half-open position (indicated by a chain double-dashed line in FIG. 12). A proximity switch 47 that can detect the position of the rear window 37 is fixed, and a detection signal from the proximity switch 47 is used as a control unit for controlling the opening and closing of the rear window 37. The microcomputer 48 (see FIG. 1). It is designed to be electrically output to.

A weather strip 49 is attached to an opening portion extending from the rear end of the rear roof rail 13 to the rear end of the rear pillar 12, and extends from the upper edge of the front end to the side edge of the front end when the rear window 37 is closed. The outer peripheral edge of the window sash 42 is tightly pressed. Similarly, a weather strip 50, which is tightly pressed against the upper edge of the waist molding 40 when the rear window 37 is closed, is attached to the lower edge of the window sash 42. It is designed to ensure airtightness.

On the other hand, as shown in FIG. 2, FIG. 6, FIG. 8, FIG. 9, and FIG. 12, a forward and reverse reversible synchronous drive motor for opening and closing the rear window 37 is provided below the left and right rear quarter panels 11. A pair of left and right body plates 53, each of which is assembled with 52 and a non-reciprocal transmission mechanism (not shown), are screwed to the body plate 53. It is pivotally attached via 55. The non-reciprocal transmission mechanism in the present embodiment is composed of a worm (not shown) integrally fitted to a rotary shaft (not shown) of the synchronous drive motor 52, and a worm wheel (not shown) meshing with the worm. The worm wheel is rotatably mounted in a gear case 56 integrally fixed to the body plate 53, and a drive pinion 57 coaxially integrated with the worm wheel is provided with a swing shaft 55 of the swing arm 54. The arc-shaped sector gears 58 coaxially and integrally attached to the swing arm 54 mesh with each other. Further, the front end of the swing arm 54 and the rear end of the sash connecting arm 43 are rotatably pinned to both ends of the pair of left and right links 59, respectively, and the rear window 37 is closed. In this state, the connecting position of the link 59 to the sash connecting arm 43 and the lengths of the links 59 are set so that the link 59 and the swing arm 54 are vertically aligned in a substantially straight line. .

Therefore, when the synchronous drive motor 52 is operated from the state shown in FIG. 12, the swing arm 54 swings clockwise around the swing shaft 55 in FIG. 12, and the swing arm 54 is rotated. With the turning motion, the rear window 37 rotates counterclockwise in FIG. 12 about the pin 45, and the rear window 37 is gradually closed. As the rear window 37 approaches the fully closed state, the swing arm 54 and the link 59 approach the dead center position where they are aligned, so the rotational angular velocity of the rear window 37 via the link 59 becomes slow. Therefore, the rotational torque of the rear window 37 will gradually increase. As a result, the outer peripheral edge of the window sash 42 continuing from the front upper edge of the rear window 37 to the front side edge is strongly pressed against the weather strip 49 continuing from the rear end of the rear roof rail 13 to the rear end of the rear pillar 12. On the other hand, the weather strip 50 attached to the lower edge of the window sash 42 is strongly pressed against the upper edge of the waist molding 40, so that the inside of the cabin 51 is reliably sealed.

As described above, by setting the link 59 and the swing arm 54 so as to be substantially vertically aligned with each other in the state where the rear window 37 is closed, the rear window 37 is attached to the rear window 37 due to its own weight. The rotation moment of the swing arm 54 toward the opening side of the window 37 can be suppressed to a small value. Further, in this embodiment, the rotational moment of the swing arm 54 toward the opening side of the rear window 37 due to the weight of the rear window 37 described above is canceled and the meshing of the drive pinion 57 and the sector gear 58 described above is achieved. In order to reduce the backlash, a spiral spring 60 that urges the swing arm 54 in the direction in which the rear window 37 is closed is interposed between the body plate 53 and the swing arm 54, and depending on the rotation direction of the synchronous drive motor 52. The load of the synchronous drive motor 52 is prevented from largely changing, while the engagement state of the drive pinion 57 and the sector gear 58 is kept constant.

Reference numeral 61 in FIG. 11 denotes a rear shelf that is attached to the tower connecting beam 25 via the rear shelf bracket 23, and 62 is attached to the central portion of the waste molding 40 in the vehicle width direction. It is a high mount stop lamp.

As shown in FIGS. 2 to 12 and FIG. 1 showing an example of the opening / closing control mechanism of the rear window 37 in the present embodiment, the rear window 37 is opened in the instrument panel in front of the driver's seat (not shown). A window opening switch 63 for closing the rear window 37, a window closing switch 64 for closing the rear window 37, and an alarm buzzer 65 for informing an occupant that the synchronous drive motor 52 is in a driving state. Is provided. The window opening switch 63 and the window closing switch 64 in the present embodiment are so-called non-lock type switches having make contacts, which output an ON signal only while the driver continues to operate, On signals from the window opening switch 63 and the window closing switch 64 are output to the microcomputer 48 described above.

The microcomputer 48 energizes the synchronous drive motor 52 and the alarm buzzer 65 based on signals from the proximity switch 47, the window opening switch 63, the window closing switch 64, and the ignition key switch 66. The current value I flowing to the synchronous drive motor 52 is for switching on / off of_S And a current value I detected by the current value detection circuit 67, which is a current value detection means for detecting_S Based on this current value I _S Is an inrush current determining means for determining whether or not the current is an inrush current when the window opening switch 63 or the window closing switch 64 is operated, and as a drive motor stop time setting means described later. And a drive motor stop time setting circuit 69. The stop of energization of the synchronous drive motor 52 and the alarm buzzer 65 is determined by the current value I detected by the current value detection circuit 67 described above._S Based on the above, the program is performed in accordance with a program set in the microcomputer 48 in advance.

For example, when the ignition key switch 66 is in the off state, the synchronous drive motor 52 and the alarm buzzer 65 are both in the non-energized state, and only when the ignition key switch 66 is in the on state, the synchronous drive motor 52 and the alarm buzzer 65 are in the on state. Energization is permitted.

Further, when the rear window 37 is in a state other than the fully closed state or the fully opened state, the alarm buzzer 65 is continuously energized, and the alarm buzzer 65 continues to be heard, so that the driver can see the rear window 37. It is known that 37 is in a halfway position. Furthermore, when the rear window 37 is rotated to move the rear window 37 from the fully open state to the fully closed state by operating the window closing switch 64, if the proximity switch 47 is switched from the off state to the on state. That is, when the rear window 37 is closed from the open state to a predetermined position, the synchronous drive motor 52 is de-energized and the rear window 37 does not close even if the window closing switch 64 is continuously operated. It is like this. Then, by temporarily interrupting the operation of the window closing switch 64 and operating the window closing switch 64 again, the energization of the synchronous drive motor 52 is resumed, and finally the rear window 37 is completely closed. Can be transferred to.

In other words, when closing the rear window 37, the rear window 37 is temporarily stopped midway, so that the rear window 37 may be inadvertently moved from the fully open state to the fully closed state. Of the switch 47, 63, 64, 66, the synchronous drive motor 52, the alarm buzzer 65, and the like in this embodiment are schematically shown in the time chart of FIG. It is represented in.

Further, the current value I flowing through the synchronous drive motor 52_S Preset lock current value I_E In the above case, while the power supply to the synchronous drive motor 52 and the alarm buzzer 65 is immediately stopped, the current value I flowing through these synchronous drive motor 52 is stopped._S Is the lock current value I_E Smaller than that, and when the rear window 37 opens and closes in a normal state, a steady-state current value (ripple current value) I flowing to the synchronous drive motor 52_R This current value I_S In this embodiment, the timing of stopping the energization of the synchronous drive motor 52 and the alarm buzzer 65 is switched in three stages according to the magnitude of the above. This operation is performed by the drive motor stop time setting circuit 69 provided in the microcomputer 48. Therefore, the drive motor stop time setting circuit 69 has a current value I_S The time from the detection of the current to the stop of the synchronous drive motor 52 is the current value I _S It is set in three stages according to.

Specifically, a high load such as an object being caught in a movable part acts, and a high load current value I corresponding to this is applied._H (However, I_E > I_H > I_R ) Flows to the synchronous drive motor 52, the drive motor stop time setting circuit 69 determines that the high load stop time T_H Select this high load current value I_H Predetermined high load stop time T_H After that, the micro computer 48 stops energizing the synchronous drive motor 52 and the alarm buzzer 65. Also, some kind of middle load works such as freezing of the movable part, and the corresponding middle load current value I_M (However, I_H > I_M > I_R ) Flows to the synchronous drive motor 52, the drive motor stop time setting circuit 69 determines that the medium load stop time T_M And select this medium load current value I_M Predetermined medium load stop time T after detection of_M After that, the microcomputer 48 stops energizing the synchronous drive motor 52 and the alarm buzzer 65. Furthermore, some low load acts on the rear window 37, and the corresponding low load current value I _L (However, I_M > I_L > I_R ) Flows to the synchronous drive motor 52, the drive motor stop time setting circuit 69 determines that the low load stop time T_L Select this low load current value I_L A predetermined low load stop time T from the detection of_L After that, the microcomputer 48 stops the energization of the synchronous drive motor 52 and the alarm buzzer 65 to ensure the safety associated with the opening / closing operation of the rear window 37.

In the present embodiment, the medium load stop time T_M The time (for example, 4 seconds) required for the rear window 37 to transition from the fully closed state to the fully opened state or from the fully opened state to the fully closed state in a normal state is adopted as the above, and thus the high load stoppage is performed. Time T_H Is the medium load stop time T_M Shorter time (for example, 2 seconds), and low load stop time T _L Is the medium load stop time T_M It takes a longer time (for example, 6 seconds).

The lock current value I _E is a current value that flows through the synchronous drive motor 52 when the rear window 37 is in a normally closed state or a fully opened state. Further, the current value detection circuit 67 in this embodiment incorporates a detection resistor (not shown) in the middle of a circuit (not shown) connected to the synchronous drive motor 52, and samples the current value flowing through this detection resistor for a predetermined time, for example, every 30 milliseconds. It is something that is done. Further, the inrush current determination circuit 68 in the present embodiment compares the current value detected two times in the past by the current value detection circuit 67 with the current value detected this time, and basically, the current value two times before. Alternatively, if the current value detected this time is smaller than the preset current value with respect to the current value detected last time, it is determined that the current value of the previous time or the previous two times is the inrush current value.

As shown in FIG. 15 showing the flow of control in this embodiment, the control flow of this embodiment is started by the ON signal of the ignition key switch 66, and the synchronous drive is first performed in step S1. The current value I _S flowing through the motor 52 is detected. Then, based on the current value I _S detected in step S1, it is determined in step S2 whether or not the inrush current has been detected, and the steps in step S1 are performed until the inrush current is detected. The step of S2 is repeated.

If it is determined in step S2 that the inrush current has been detected, the process proceeds to step S3, and the current value I _S detected in step S1 is the preset lock current. determines whether the value is I _E above, this current value I _S is greater than or equal to the lock current value I _E, that is, when it is determined that the lock current flows in the synchronous drive motor 52, S4 Then, the power supply to the synchronous drive motor 52 and the alarm buzzer 65 is stopped.

If it is determined in step S3 that the current value I _S is less than the lock current value I _E , the current value I _S is greater than or equal to the high load current value I _{H in} step S5. It is determined whether or not If it is determined that the current value I _S is less than the lock current value I _E and is equal to or more than the high load current value I _H , that is, a relatively large external force is acting on the rear window 37, the step S6 is performed. At, it is determined whether or not the count-up of the timer (not shown) has started. At first, since the timer count-up has not started, the timer count-up is started in step S7, and then it is determined whether or not the timer count value T _C is equal to or higher than the preset high load stop time T _H. Is determined in step S8. In this case, since the count value T _{C of the} timer is smaller than the high load stop time T _{H at} first, the steps after S1 are repeated. The second and subsequent, until since the counting up of the timer at the start already, proceeds directly to step S8 from step S6, the count value T _C of the timer goes high load stopping time T _H or S1 to S3, S5 , S6, S8 are repeated. Then, at step S8 the count value T _C of the timer when it is determined that the high load stopping time T _H or more, the process proceeds to step S9 to reset the count value T _C of the timer to 0, In step S4, the energization of the synchronous drive motor 52 and the alarm buzzer 65 is stopped.

When it is determined in step S5 that the current value I _S is less than the high load current value I _H , the process proceeds to step S10, and the detected current value I _S is the medium load current value I _M. It is determined whether or not the above. If it is determined that the current value I _S is less than the high load current value I _H and more than the medium load current value I _M , that is, a medium external force acts on the rear window 37, S11 is performed. In the step, it is determined whether or not the count-up of the timer (not shown) has started. At first, since the timer count-up has not started, the timer count-up is started in step S12, and then the timer count value T _C is equal to or greater than the preset medium load stop time T _M. Whether or not it is determined in step S13. In this case, since the count value T _{C of the} timer is smaller than the medium load stop time T _M at first, the steps after S1 are repeated. The second and subsequent timer counts up the already started der Runode until proceeds directly to S13 in step from step S11, count value T _C of the timer is the middle load stop time T _M or S1~S3 , S5, S10, S11, S13 are repeated. When it is determined in step S13 that the timer count value T _C is equal to or longer than the medium load stop time T _M , the process proceeds to step S9 to reset the timer count value T _C to 0, The process proceeds to step S4, and the energization of the synchronous drive motor 52 and the alarm buzzer 65 is stopped.

Further, in the step S10, the current value I_S Is the medium load current value I_M If it is determined that the current value I is less than_S Is the low load current value I_L It is determined whether or not the above. And this current value I_S Is the medium load current value I_M Less than and low load current value I_L When the above is determined, that is, when it is determined that a relatively small external force is acting on the rear window 37, it is determined in step S15 whether or not the count-up of a timer (not shown) has started. At first, since the timer count-up has not started, the timer count-up is started in step S16, and then the count value T of this timer_C Low load stop time T preset by_L Whether or not the above is determined in step S17. In this case, first, the low load stop time T_L Than the count value T of the timer_C Is smaller, the steps after S1 are repeated. Since counting up of the timer has already started from the second time onward, the process directly moves from step S15 to step S17, and the count value T of the timer is counted._C Is low load stop time T_L The steps S1 to S3, S5, S10, S14, S15, and S17 are repeated until the above is reached. Then, in step S17, the count value T of the timer_C Is low load stop time T_L If it is determined that the above is the case, the process proceeds to step S9 and the count value T of the timer is counted. _C Is reset to 0, and the process proceeds to step S4 to stop energizing the synchronous drive motor 52 and the alarm buzzer 65.

On the other hand, when it is determined in step S14 that the current value I _S is less than the low load current value I _L , that is, the ripple current of the steady current value I _R flows in the synchronous drive motor 52, Has no problem, the process returns to step S1 again to detect a new current value I _S.

As described above, in this embodiment, when the current value I _S is located between the low load current value I _L and the high load current value I _H , the energization of the synchronous drive motor 52 is stopped after a predetermined time. However, the energization direction for the synchronous drive motor 52 may be switched to the opposite direction after a predetermined time.

In this embodiment, the present invention is applied to the opening / closing control device for the rear window of a two-door type passenger car with a built-in rear seat, but the present invention is also applied to windows and shutters other than door windows and automobiles. It can be applied.
