Reference numeral 39 denotes each switch unit 21a-21d, 26-
A central processing unit (control means) for controlling the motor drive circuit 31 and the display device 38 according to the operation of 28 and the position of the sunroof 1, which is controlled based on a control program stored in the ROM 40. Reference numeral 41 denotes a RAM that stores the opening / closing amount set by the first to fourth setting switch units 21a to 21d and other data.

Next, the operation of the above embodiment will be described with reference to FIGS.
A description will be given based on the flow chart shown in FIG.

First, when the sunroof mode is switched by operating a mode selector switch (not shown), an image is displayed on the display screen 12 as shown in FIG. And
In step 1, the display screen 12 is displayed according to the current position of the sunroof 1 (position of the tip 1a of the sunroof 1 shown in FIG. 2) C _P.
Shown in. This current position C _P is obtained from the number of pulses output from the pulse generator 32.

Now, for example, when the sunroof 1 is fully closed, the pulse is not output from the pulse generator 32 because the sunroof 1 is not moving. That is, C _P is zero, and it is determined that the central processing unit 39 is fully closed based on this C _P , and the divided image 13
Display a to 13d in brown. This state is shown by the diagonal lines in FIG.

In step 2, each of the switch parts 21a-2
It is determined whether or not 1d, 26 to 28 are pressed, and when not pressed, the process returns to step 1 and each switch unit 21
Steps 1 to a to 21d, 26 to 28 are touched
The operation of step 2 is repeated. And. For example, when the third setting switch section 21c is touched, it is determined as YES in step 2 and the process proceeds to step 3.

In step 3, it is determined whether or not the fully open switch portion 28 has been touched. Here, since the third setting switch unit 21c is touched, the process proceeds to step 4.

At step 4, each of the switch parts 21a-2
The target value C _m corresponding to 1d is stored in the RAM 41. Here, since the third setting switch unit 21c is touched, the target position C _m is the number of pulses corresponding to ½ opening in the RAM.
41 will be stored. Further, as shown in FIG. 6, the divided image 13c is displayed in gray for a predetermined time to indicate that the third setting switch portion 21c is touched.

In step 5, the current position C _p of the sunroof 1 and the target position C _m are compared. If the current position C _p is smaller than the target position C _m , the process proceeds to step 6, and if it is larger, the process proceeds to step 11. .. Here, since the sunroof 1 is fully closed, the determination is yes, and the process proceeds to step 6 shown in FIG.

In step 6, the fully open limit switch 3
It is determined whether or not 3 is turned on. If yes, the process proceeds to step 10, and if no, the process proceeds to step 7. Here, since the sunroof 1 is fully closed, the routine proceeds to step 7.

In step 7, the motor 30 is driven in the normal direction to move the sunroof 1 rearward. In step 8, counts the number of pulses output from the pulse generator 32, adds the current position C _p of the sunroof 1 to the count number, obtains the position C _p of the sunroof 1 the current.

In step 9, the divided images 13a, 13b corresponding to the front side (closed side) of the turned-on third setting switch unit 21c, that is, the first and second setting switch units 21a, 21b.
As shown in FIG. 7, the light blue blinking is displayed and the process returns to step 5. The operations of steps 5 to 9 are repeated until the sunroof 1 is opened to 1/2, that is, the position C _{p of the} sunroof 1 and the target position C _m become equal. The light blue blinking display of the divided images 12a and 13b indicates that the sunroof 1 is moving in the opening direction.

When the sunroof 1 is opened up to 1/2, that is, when the position C _p and the target position C _m become equal to each other, it is determined no in step 5, and the process proceeds to step 11. In step 11, since the position C _p and the target position C _m are equal, it is determined to be no and the process proceeds to step 12. In step 12, the normal rotation drive of the motor 30 is stopped, which causes the sunroof 1
Movement is stopped. That is, the sunroof 1 is 1/2
Open until stopped.

At step 13, as shown in FIG. 8, the divided images 13a and 13b are displayed in light blue and the process returns to step 1. The divided images 13c and 13d are displayed in brown.

Next, the case where the sunroof 1 is opened up to 1/2 and the sunroof 1 is opened up to 1/4 will be described.

First, when the second setting switch section 21b is touched, the same operation as above is performed from step 1 to step 4, and the divided image 13b is displayed in gray for a predetermined time as shown in FIG. .

At step 5, since the position C _p of the sunroof 1 is larger than the set target value C _m , it is judged as no and the routine proceeds to step 11.

In step 11, the position C of the sunroof 1 is set.
_{Since p} is larger than the target position C _m , YES is determined in step 11 and the process proceeds to step 14. In step 14, it is determined whether or not the fully closed limit switch 34 is turned on. Here, since the sunroof 1 is in a state of being opened to 1/2, it is determined to be no. In step 15, the motor 30 is driven in the reverse direction, whereby the sunroof 1 is moved forward.

In step 16, the position C of the sunroof 1 is set.
_The current position C _p of the sunroof 1 is obtained by subtracting the number of pulses output from the pulse generator 32 from _p . In step 17, the divided image 13b, which is the portion between the current position C _p of the sunroof 1 and the turned-on second setting switch portion 21b, is displayed in a blinking brown color as shown in FIG.
From this blinking display, it can be seen that the sunroof 1 is moving forward.

The operations of step 5, step 14 to step 17 are repeated until the sunroof 1 reaches the target position C _m .

When the position C _p reaches the target position C _m , it is judged no in step 11 and the routine proceeds to step 12, where the driving of the motor 30 is stopped. As a result, the sunroof 1 is in a state of being opened by 1/4.

At step 13, as shown in FIG.
The divided image 13b is displayed in brown. The divided image 13a is displayed in light blue, and the divided images 13c and 13d are displayed in brown. From these displays, it can be seen that the sunroof 1 is open only by 1/4. Then, the process returns to step 1.

When the first setting switch portion 21a is touched to instruct full closing, the operations of steps 5, 11, 14 to 17 are repeated until the sunroof 1 is fully closed. When the sunroof 1 is fully closed,
When it is judged as YES in step 14, the process proceeds to step 18. In step 18, the position C _{p of the} sunroof 1 is reset and set to zero. Then, in step 12, the driving of the motor 30 is stopped, and in step 13, the divided image 1
Display 3a to 13d in brown and return to step 1.

Next, the case where the fully open switch 28 is touched from the fully closed state shown in FIG. 3 will be described.

When the fully open switch 28 is touched, the same operation as described above is performed from step 1 to step 2, and the process proceeds to step 3. In step 3, it is judged as yes and the process proceeds to step 6. Since the sunroof 1 is fully closed, it is judged no in step 6 and the process proceeds to step 7.

In steps 7-9, the sunroof 1 is moved rearward as described above, and the divided images 13a-
13d is blinked in light blue and the process returns to step 5 and the operations of steps 5 to 9 are repeated until the sunroof 1 is fully opened. When the sunroof 1 is fully opened and the fully open limit switch 33 is turned on, it is determined as YES in step 6 and the process proceeds to step 10.

At step 10, the target data C _m is corrected. This is because the number of pulses output from the pulse generator 32 does not always become the same every time the sunroof 1 moves from the fully closed state to the fully open position, and this is corrected each time.

That is, the number of pulses when fully opened is N (=
When C _p ), the target value C _m of the touch switches 22, 23, 24 is rewritten to N / 4, 2N / 4, 3N / 4, and thereafter the position of the sunroof 1 is controlled using this data. Is.

In step 12, the driving of the motor 30 is stopped, and in step 13, the divided images 13a to 13d are displayed in light blue to indicate that the sunroof 1 is fully opened, and the process returns to step 1.

In this way, the switch parts 21a to 21d, 2
The operation is very simple because the sunroof 1 is moved to the desired position simply by pressing 8. Further, since the moving position of the sunroof 1 is displayed in the divided images 13a to 13d, it is not necessary to directly view the sunroof 1, which is very convenient.

In the above embodiment, the position of the sunroof 1 is set to 4
Although it can be set in stages, it is not limited to this. Further, although the setting switch sections 21a to 21d are provided on the divided images 13a to 13d, they may be provided separately. For example, the display screen 12 may be provided at a position adjacent to the display screen 12.
In addition, the position of the sunroof 1 may be displayed as a bar graph in length, and the length may be continuously changed according to the moving position of the sunroof 1. Also, the switch unit 21a
21d and 28 may not be touch switches.

[0047]

According to the present invention, the sunroof can be moved to a desired position only by setting the opening / closing position by the position setting means, and therefore the operation is very simple. Further, since the moved position of the sunroof, that is, the opened / closed state is displayed on the display screen, it is not necessary to directly see the sunroof, which is very convenient.
