Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a sunroof device which is driven by a driving means such as a motor to open and close an opening of a vehicle body.

[Prior Art] Conventionally, a sunroof device disclosed in Japanese Utility Model Laid-Open No. 1-98723 has been proposed. This device is provided with a fully open limit switch and a fully closed limit switch at the opening edge of the vehicle body, while the sunroof has convex portions that come into contact with the limit switches at the fully open position and the fully closed position. It is provided. Then, when the sunroof reaches the fully closed position or the fully open position and the convex portion comes into contact with any of the corresponding limit switches, the limit switch is turned off, and the power supply circuit of the motor that is the drive means of the sunroof is Be cut off. As a result, the motor stops and the sunroof stops at the fully open position or the fully closed position.

[Problems to be Solved by the Invention] However, in such a conventional device, as described above, the limit switch provided at the opening edge of the vehicle body is contacted with the convex portion provided on the sunroof. By making contact with each other, the power supply circuit of the motor is cut off. Therefore, when the sliding locus of the sunroof with respect to the vehicle body opening is displaced due to vehicle body vibration or the like, the convex portion provided on the sunroof can accurately contact the limit switch arranged at the opening edge of the vehicle body. It will be difficult.

Therefore, even if the sunroof reaches the fully open position or the fully closed position, the convex portion cannot contact the limit switch, and the limit switch remains in the ON state.
As a result, even after the sunroof is fully opened or fully closed, the motor continues to rotate, which causes an excessive load on the motor, which may damage the motor.

The present invention has been made in view of such a conventional problem, and does not depend only on the operation of the limit switch, but the stop control of the drive means is performed according to the arrival of the sunroof at the fully open position or the fully closed position. It is an object of the present invention to provide a sunroof device capable of performing the above-mentioned operation, and further, capable of performing the stop control of the drive means more accurately.

[Means for Solving the Problems] In order to solve the above problems, in the present invention, the opening operation time when the sunroof driven by the driving means slides in the opening direction from the fully closed position, and the fully opened position. A timer is provided for respectively measuring the closing operation time when sliding in the closing direction from the to, and when each operation time measured by the timer reaches the opening setting time and the closing setting time, the drive means is provided. Is a sunroof device having drive control means for stopping the sunroof, the position detection means for detecting a sliding position of the sunroof is provided, and the drive control means is provided according to the position of the sunroof detected by the position detection means. There is provided initial value setting means for variably setting the open set time and the close set time at the time of starting.

Here, the open set time is a time that exceeds a time required for the sunroof to move from the fully closed position to the fully open position by a predetermined time, and the open set time is the open time of the sunroof from the fully open position to the fully closed position. This is a time that is longer than the time required to move to the position by a predetermined time.

[Operation] In the above configuration, when the drive means is operated, the sunroof is driven by the drive means to slide, thereby opening and closing the vehicle body opening. At this time, the drive means is controlled by the drive control means, and when the sunroof is operated in the opening direction from the fully closed position, the opening operation time is measured by the timer, and the measured opening operation time is preset. When the closing set time is reached, the drive means is stopped. When the sunroof is operated in the closing direction from the fully open position, the closing operation time at this time is measured by a timer, and when the measured opening operation time reaches a preset closing setting time, The drive means is stopped.

That is, the drive means operates within a preset open time or close preset time to drive the sunroof in the open and close directions. At this time, since the open set time is a time longer than the time required for the sunroof to move from the fully closed position to the fully open position by a predetermined time as described above, the drive means is set at the open set time. When is activated, the sunroof is sure to reach the fully open position.

The same applies to the closing set time, and when the drive means operates at the closing set time, the sunroof surely reaches the fully closed position and the sunroof reaches the fully closed position, and the set time is set. When the time has passed, the driving means is stopped.

Then, when the drive control means thus executes the control for the drive means for driving the sunroof,
The position of the sunroof at the time of starting is detected by the position detecting means, and the initial value setting means variably sets the open setting time and the close setting time according to the position of the sunroof. Therefore, for example, even if the sunroof is slid manually before the drive control means is started, and the position of the sunroof is changed by this, the open setting time and the close setting time corresponding to the changed position have initial values. Then, the control of the driving means is started.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIG. 2, the roof 2 of the vehicle body 1 is provided with an opening 3, and the opening 3 is slidable from the fully closed position P _C to the fully open position P _O. 4 are provided. A motor 5 as driving means shown in FIG. 1 is linked to the sunroof 4, and the motor 5 is connected to a movable contact 7 of a first relay 6 and a movable contact 9 of a second relay 8. There is. The first and second relays 6,
The coils 10 and 11 of 7 have one end connected to the positive electrode of the battery and the other end connected to the output port of the controller 12 which is the drive control means and the initial value setting means in the present embodiment.

The controller 12 is a microcomputer and has an open timer 13 and a close timer 14 built therein. As shown in FIG. 2, the open timer 13 has a function of measuring the open operation time when the sunroof 4 moves from the fully closed position P _C toward the fully open position P _O , and the closed timer 14 Has a function of measuring the closing operation time when the sunroof 4 moves from the fully open position P _O toward the fully closed position P _C.

In FIG. 2, t _AL indicates that the sunroof 4 is from the fully closed position P _C to the fully open position P _O , and from the fully open position P _O to the fully closed position.
This is the travel time required to move to P _C. Then, a value t _AL + t _{MIN-CL that} is a predetermined time t _MIN-CL higher than the movement required time t _AL in the closing direction is a closing set time, and the movement required time t _AL is set in the opening direction by a predetermined value. A value that exceeds the time t _{MIN-OP by} t _AL + t _MIN-OP is the open set time. Further, a fully closed limit switch 15 and a fully open limit switch 16 as position detecting means are connected to the input port of the controller 12, and the fully closed limit switch 15 is normally off, and the sunroof 4 Is turned on when it reaches the fully closed position P _C , and the fully open limit switch 16 is normally off, and is turned on when the sunroof 4 reaches the fully opened position P _O.

Further, a sunroof switch 19 is connected to the input port of the controller 12, and the sunroof switch 19 is provided with a closed switch contact 17 and an open switch contact 18.

Next, the operation of the present embodiment according to the above configuration will be described.
Description will be given according to the flowchart shown in FIG. That is, the flow chart shown in FIG. 3 shows the initialization process when the main routine shown in FIG. 5 described later is started, and when an ignition switch (not shown) is turned on, step A1 is executed. Judgment is YES
Then, it is determined whether or not the fully closed limit switch 15 is turned on (step A2).

If this determination is YES, the controller 12 determines that the motor 5
It means that the sunroof 4 is in the fully closed position P _C at the time of starting the control for. Therefore, in this case, the process proceeds to step A4 and the timer set is executed. This timer set, as shown in FIG.
Is set to the initial value t _AL + t _MIN-OP.
This is the process of setting _MIN-CL .

Therefore, when the ignition switch is turned on while the sunroof 4 is in the fully closed position P _C , the open timer 13 is set to the open set time t _AL + t _MIN-OP (for example,
t _AL = 10 seconds, t _MIN-OP = 5 seconds), and the close timer 14 is set to the close set time t _MIN-CL (for example, t _MIN-CL = 5).
Seconds), the controller 12 starts the control shown in FIG.

On the other hand, if the determination in step A2 is NO, then it is determined whether or not the full-open limit switch 16 is on (step A3). If this determination is YES, it means that the sunroof 4 is at the fully open position P _O when the controller 12 starts controlling the motor 5.
Therefore, in this case, the process proceeds to step A6 and the timer set is executed. This timer set sets the initial value t _MIN-OP to the open timer 13 and the close timer 14 as shown in FIG. Is a process to set t _AL + t _MIN-CL . Therefore, when the ignition switch is turned on with the sunroof 4 in the fully open position P _O , the open timer 13 is set to the open set time t _MIN-OP , and the close timer 14 is set to the closed set time t. _AL + t _MIN-CL is set, and the controller 12 starts the control shown in FIG.

If both the determinations in step A2 and step A3 are NO, the sunroof 4 will be at the fully open position P _O and the fully closed position P _{C at} the time when the controller 12 starts controlling the motor 5.
It means that it is in the half-open position. Therefore, in this case, the process proceeds to step A5 to execute the timer set, and the timer set sets the initial value t _AL + t _MIN-OP to the open timer 13 as shown in FIG. 14 is a process for setting the initial value t _AL + t _MIN-CL . Therefore, when the ignition switch is turned on when the sunroof 4 is in the half-open state, the open timer 13 is set to the open set time t _AL + t _MIN-OP and the close timer is set.
The closing set time t _AL + t _MIN-CL is set in 14, and the controller 12 starts the control shown in FIG.

Then, after such initialization processing is completed, the main routine shown in FIG. 5 is started, and when the sunroof switch 19 is turned on in the main routine, the determination in step B1 becomes YES, Next, it is judged whether or not the sunroof switch 19 is turned on at the open switch contact 18 side (step B2).
If this determination is YES and the open switch contact 18 is operated to be turned on, the coil 10 of the first relay 6 is excited and the movable contact 7 of the first relay 6 is connected to the battery. Contact fixed contacts. Therefore, the motor 5 starts to rotate in the forward direction, and the sunroof 4 starts sliding in the fully open position P _O , that is, the opening operation (step B3).

Then, the open timer 13 subtracts from the value of the open set time t _MIN-OP or t _AL + t _MIN-OP set at this time, and at the same time, the close timer 14 sets the close set time to the closed set time. The value is added to either t _MIN-CL or t _AL + t _MIN-CL (step B4). That is, when the sunroof 4 slides in the opening direction, the open timer 13 operates, for example, in units of seconds for the operation time of the sunroof 4 toward the fully open position P _O ,
More specifically, the operating time of the motor 5 is subtracted from the set open time for measurement, and the closed timer 14 measures the total moving time from the set open time.

Next, it is judged whether or not the full-open limit switch 16 is turned on (step B5). If the judgment is NO, it is further judged that "open timer = 0", that is, the open timer 13 is set to the initial value t _{MIN. -OP} or t _AL + t _MIN-OP is subtracted to determine whether or not the value has been counted down to "0". If the determination is NO, the process returns to step B1 and from step B1. Repeat the loop of step B6.

When the determination in step B5 is YES during execution of this loop, the full-open limit switch 16 is functioning normally, and the sunroof 4 is set to the full-open position P _O only by turning on the full-open limit switch 16. It turns out that it has arrived. Therefore, at this point, the open timer 13
As a result, since it is no longer necessary to perform subtraction, the open timer 13 is stopped and (step B
7), the coil 10 of the first relay 6 is demagnetized,
The power supply circuit of the motor 5 is cut off, the sunroof 4 is stopped (step B8), and the closing timer 14 that was performing the integration
To reset the initial value (step B9).

On the other hand, even after the sunroof 4 reaches the fully open position P _O , if the state of NO in step B5 continues, it means that the fully open limit switch 16 is not operating normally. The loop of steps B1 to B6 is repeated until the determination of B6 is YES. And
When the value of the open timer 13 reaches "0", step B6
If the determination is YES, the processes of steps B7, B8, B9 described above are executed, and the sunroof 4 stops at the fully open position P _O.

That is, even if the full-open limit switch 13 does not function normally, the motor 5 can set the open set time t
_Operates only at _MIN-OP or t _AL + t _MIN-OP , then stops. At this time, the open set time t _MIN-OP or t _AL
+ T _MIN-OP is a value set according to the position of the sunroof 4 at the time when the control of the sunroof 4 motor 5 is started as described above, and t _AL + t _MIN-OP
Is a time that exceeds the required time t _AL (10 seconds) required to move from the fully closed position P _C to the fully open position P by t _MIN-OP (5 seconds), so this open set time t _AL + t
When the motor 5 operates with _MIN-OP (15 seconds), the sunroof 4 surely reaches the fully open position P _O from the fully closed position P _C.

Therefore, for example, the sunroof, which was in the fully open position P _C when the ignition switch was turned off, was manually moved to the half open or fully open position P _O , and in this state the controller
Even when 12 is activated, the sunroof 4 can be reliably driven to the fully closed position P _C.

Even when the sunroof 4 is in the fully open position P _C , even when the sunroof switch 19 is turned on to the open switch contact 17 side and the sunroof 4 is further driven to open, the motor 5 keeps the initial value t. _It only works with _MIN-OP (5 seconds). Therefore, excessive load is not applied to the motor 5 for a long time, and damage to the motor 5 when the full-open limit switch 15 does not operate normally can be prevented.

On the other hand, if the determination is NO in step B2 and the close switch contact 17 is operated so as to be turned on, the coil 11 of the second relay 8 is excited and the movable contact 9 of the second relay 8 becomes a battery. Contact the fixed contacts that are connected.

Therefore, the motor 5 starts reverse rotation, thereby, the sunroof 4 is slid to the fully closed position P _C direction, i.e. starts closing operation (Step B10). Then, the closing timer 14 sets the closing set time t _MIN-CL set at this time.
Or, the value is subtracted from any one of t _AL + t _MIN-CL , and at the same time, the open timer 13 integrates to any value of the closed set time t _MIN-OP or t _AL + t _MIN-OP ( Step
B11). That is, when the sunroof 4 slides in the closing direction, in the closing timer 14, for example, the moving time of the sunroof 4 in the direction of the fully closed position P _{C in} seconds, more specifically, the operation of the motor 5. The time is subtracted from the open set time and measured, and in the open timer 13, the moving time is integrated from the set value.

Next, it is determined whether or not the fully closed limit switch 15 is turned on (step B12), and if this determination is NO, it is further determined that "closed timer = 0", that is, the closed timer 14 has the initial value t. By subtracting from _MIN-CL or t _AL + t _MIN-CL, it is determined whether or not the countdown has reached "0". If this determination is NO, the process returns to step B1 and the step B1 Repeat the loop from B2, B10, B11, B12, B13.

Then, when the determination in step B12 is YES during execution of this loop, the fully closed limit switch 15 is functioning normally, and the sunroof 4 is fully opened only by the ON operation of the fully closed limit switch 15. It turns out that _C has been reached. Therefore, at this point the already closed timer
Since it is no longer necessary to perform the subtraction by 14, the stop timer 14 is stopped and (step
B14), the coil 11 of the second relay 8 is demagnetized, the power circuit of the motor 5 is shut off, the sunroof 4 is stopped (step B15), and the open timer 13 that was performing the integration is reset. Set the initial value (Step B1
6).

On the other hand, even after the sunroof 4 reaches the fully closed position P _C , if the state of NO in step B13 continues, it means that the fully closed limit switch 15 is not operating normally. The loop of steps B1 to B2, B10, B11, B12, B13 is repeated until the determination in step B13 becomes YES. Then, when the value of the closing timer 14 reaches “0”, and the determination in step B13 is YES, the processing in steps B14, B15, B16 described above is executed, and the sunroof 4 is at the fully closed position P _C. Stop.

That is, even if the fully closed limit switch 15 does not function normally, the motor 5 can set the open set time t
_Operates only at _MIN-CL or t _AL + t _MIN-CL , then stops. At this time, the open set time t _MIN-CL or t _AL
+ T _MIN-CL is a value set according to the position of the sunroof 4 at the time when the control of the motor 5 is started as described above, and t _AL + t _MIN-CL is the fully open position P _O.
Time required to move from to closed position P _C to t _AL
Since it is a time that exceeds (10 seconds) by t _MIN-CL (5 seconds), if the motor 5 operates with this open set time t _AL + t _MIN-CL (15 seconds), the sunroof 4 will surely move. Reach the fully closed position P _C.

Therefore, for example, the sunroof, which was in the fully closed position P _C when the ignition switch was turned off, was manually moved to the half open position or the fully open position P _O.
Even when 12 is activated, the sunroof 4 can be reliably driven to the fully closed position P _C.

Even when the sunroof 4 is in the fully open position P _C , even when the sunroof switch 19 is turned on to the open switch contact 17 side and the sunroof 4 is further driven to open, the motor 5 keeps the initial value t. _It only works with _MIN-CL (5 seconds). Therefore, an excessive load is not applied to the motor 5 for a long time, and damage to the motor 5 when the fully closed limit switch 15 does not operate normally can be prevented.

Note that the real values such as 5 seconds, 10 seconds, and 15 seconds used in the present embodiment are examples, and values corresponding to the actual operating characteristics of the sunroof 4 may be appropriately used.

FIG. 6 shows a second embodiment of the present invention, in which the vehicle body 1 has a fully closed limit switch 15 which is turned on when the sunroof 4 is at the fully closed position P _C and a fully open position P _O. In addition to the fully open limit switch 16 which is turned on, an intermediate limit switch 20 as a position detecting means is provided. The intermediate limit switch 20 has the fully closed position P _C and the fully open position.
It is located between P _{O and} at an intermediate position P _N , which is slightly closer to the fully closed position P _C. In addition, in FIG. 6, t _AL , t
The values of _MIN-OP and t _MIN-CL are the same as those in the above-mentioned embodiment,
Also, t _FR is the time required to move the sunroof 4 from the fully closed position _PC to the intermediate position P _N , and t _RR is the time required to move from the intermediate position P _N to the fully open position P _O.
It shows the time required to move to.

In the present embodiment having the above configuration, the controller
At the time of starting, 12 executes the initialization processing as shown in FIG. That is, when the ignition switch is turned on (step C1), first, it is determined whether or not the intermediate limit switch 20 is turned on (step C).
2). If this determination is YES, it means that the sunroof 4 is in contact with the intermediate limit switch 20, so it is in the fully closed state, or its tip is located within the area α shown in FIG. It is in a semi-open state. Therefore, if the determination in step C2 is YES, then it is determined whether or not the sunroof 4 is in the fully closed state by determining whether or not the fully closed limit switch 15 is next turned on ( Step C3).

If this determination is YES, the sunroof 4 is at the fully closed position P _C.
Therefore, the timer set is executed, and as shown in FIG. 8, the open timer 13 is set to t _AL + t _MIN-OP as the initial value, and the closed timer 14 is set to t _MIN-CL as the initial value. Set.

If the determination in step C3 is NO, the sunroof 4
Is located in the region α and is near the fully closed position P _C although it is in the half open state. Therefore, in this case, the timer set is executed, t _AL + t _MIN-OP is set in the open timer 13, and t _FR + t _MIN-CL is set in the close timer 14.

On the other hand, if the determination in step C2 is NO, the sunroof 4
Indicates that it is not in contact with the intermediate limit switch 20, and therefore is in the fully open state, or is in the half open state in which the tip portion thereof is located within the region β shown in FIG. Therefore, if the determination in step C2 is NO, then it is determined whether or not the sunroof 4 is in the fully open state by determining whether or not the fully open limit switch 16 is turned on next (step C6). ).

If this determination is YES, the sunroof 4 is in the fully open position P.
Therefore, execute the timer set (step C
8) As shown in FIG. 8, the open timer 13 is set to t _MIN-OP as an initial value, and the close timer 14 is set to t _AL + t _MIN-CL as an initial value.

If the determination in step C6 is NO, the sunroof 4
Is located in the region β and is near the fully open position P _O although it is in a half open state. Therefore, in this case, the timer set is executed (step C7), and the open timer 13 is set to t.
Set _RR + t _MIN-OP , and close timer 14 with t _AL +
t Set _MIN-CL .

That is, as can be understood by comparing FIGS. 4 and 8, in the above-described embodiment, when the sunroof 4 is in the half-open position, the open timer 13 is set to t _AL + t.
Set _MIN-OP as the initial value and set the close timer 14 to t _AL.
In contrast to the one type of pattern in which + t _MIN-CL is set as the initial value, in the second embodiment, each pattern of the timer set and the timer set is set according to the position of the sunroof 4 even in the half open state. Is selected and used.

If t _RR + t _MIN-OP is set as the initial value in the open timer 13 by the timer set, the value is subtracted from this value and the motor 5 is stopped, so that the motor 5 continues to rotate after full opening. Can be reduced, and the time during which a high load is applied to the motor 5 can be further reduced. Further, if the closed timer 14 is set to t _FR + t _MIN-CL as an initial value by the timer set,
By subtracting from this value and stopping the motor 5, the time during which the motor 5 continues to rotate after fully closing is reduced, and similarly, the time during which a high load is applied to the motor 5 is reduced. You can

Therefore, according to the second embodiment, it is possible to further reduce the generation of unnecessary load on the motor 5, and it is possible to improve the durability of the motor 5.

[Effects of the Invention] As described above, according to the present invention, the opening operation time and the closing operation time of the sunroof exceed the movement required time from the fully closed position to the fully opened position of the sunroof by a predetermined time, and The drive means for the sunroof is stopped when the closing maximum set time, which exceeds the time required for moving from the fully open position to the fully closed position by a predetermined time, is reached.

Therefore, without depending only on the limit switch for detecting the fully open position and the fully closed position of the sunroof,
The drive means can be stopped after the sunroof has reached the fully open position and the fully closed position, which can improve the reliability of the sunroof device.

Also, since the initial values of the open and closed set times are variably set according to the position of the sunroof, it is possible to manually operate the sunroof at any position when the drive control means for controlling the drive means is started. Even in the initial operation, the sunroof can surely reach the fully open position or the fully closed position.
