On the other hand, in step 103, the keyless remote controller 62 is activated, the process proceeds to the next opening / closing and buzzer control 300 by the keyless controller 62, and then the process returns.

 Next, the opening / closing and buzzer control 300 will be described.

The operation flow of this control is shown in FIG. 5. First, in step 301, it is determined whether or not the keyless remote control switch 4 has been operated. If NO, this determination is repeated and YES is determined. If so, go to step 302.

In step 302, a process of outputting a Hi signal to the transistor 624 is performed, and power is supplied to each of the limit switches 81 to 83, and the process proceeds to step 303.

In step 303, the operated switch is the open switch 4
Whether the switch is 1 or the closed switch 42 is determined to be open / closed. If the switch is the open switch 41, the process proceeds to step 304. If the switch is the closed switch 42, the process proceeds to step 305.

In step 304, it is determined whether or not the full open limit switch 81 is closed, and if YES, the process proceeds to step 306, and if NO, the process proceeds to step 307.

In step 307, the process of driving the motor 2 to the open side is performed, and the process proceeds to step 308.

In step 308, it is determined whether or not the open switch 41 is released. If NO, the process returns to step 304, and if YES,
Go to step 306.

In step 306, the process of stopping the driving of the motor 2 is performed, and then the process returns.

On the other hand, if the process proceeds from step 303 to step 305, in step 305 it is determined whether or not the fully closed limit switch 82 is in the open state, and if YES, the process proceeds to step 306 to stop the driving of the motor 2 and NO. If there is, go to step 309.

In step 309, it is determined whether or not the intermediate switch 83 is in the closed state, and if YES, the process proceeds to step 310,
If NO, go to step 311.

In step 310, the motor 2 is driven to the closed side and the buzzer 9 generates an intermittent sound, and the process proceeds to step 312.

In step 312, it is determined whether or not the fully closed limit switch 83 is opened, and if YES, step 313

Then, the process proceeds to step 306, the motor stop process is performed, and then the process returns.

 Next, the operation of the embodiment apparatus will be described.

(A) When riding When the driver gets on the vehicle and starts the engine, the ignition switch 7 changes from the start position to the on position.

Therefore, as shown in the switching control of FIG. 4, the rear seat remote controller 61 is activated and the rear seat remote controller switch 3
Also, the opening / closing operation of the sunroof 1 is performed by the front opening / closing switch 5.

Therefore, when driving the engine in this way,
Even if the keyless remote control switch 4 is operated to open / close, the sunroof 1 is not opened / closed.

(B) When getting off When the drive of the engine is stopped by setting the ignition switch 7 to the accessory position or the off position, the operation of the rear seat remote controller 61 is stopped and the keyless controller 62 is started.

Therefore, in this case, the keyless remote control switch 4
The opening / closing control of the sunroof 1 can be performed only by.

Next, regarding the operation when opening and closing the sunroof 1,
A case where the keyless remote control switch 4 is operated will be described as an example.

(C) When the sunroof is opened When the keyless remote control switch 4 is operated, a Hi signal is output to the transistor 624 regardless of whether the sunroof is opened or closed. As a result, a dark current is supplied to each of the limit switches 81 to 83, and the sunroof 1 The state can be detected.

Therefore, when the open switch 41 is operated in this opening / closing operation, the motor 2 is driven to open. Then, this open drive is maintained until the operation of the open switch 41 is stopped halfway or the full open limit switch 81 is closed.

(B) When the sunroof is closed When the closing switch 42 of the keyless remote control switch 4 is operated, the motor 2 is closed (when the fully closing switch 82 is not opened).

Further, the sunroof 1 is closed by driving the motor 2 in this manner.
When the closed slide of is performed, the buzzer 9 makes an intermittent sound (first
Warning sound) is emitted.

Therefore, it is possible to confirm that the sunroof 1 has been closed and slid even if the remote control is performed outside the vehicle at a position where the sunroof 1 cannot be viewed. Further, it is possible to warn a person who has not performed an opening / closing operation that the sunroof 1 will be closed and call attention to the person.

When the sunroof 1 slides to the 250 mm position before the fully closed position and the intermediate limit switch 83 is closed,
Once the operation of the buzzer 9 is stopped, the closing drive of the motor 2 is stopped.

 Therefore, at this time, safety confirmation can be performed.

Then, when the operation of the closing switch 42 is continued, the buzzer 9 generates an intermittent sound again and the motor 2 is driven to close,
The closed slide of the sunroof 1 is completed.

After that, when the fully closed limit switch 82 is opened, the closing drive of the motor 2 is stopped, and the buzzer 9 switches to a continuous sound (second alarm sound).

The operation of the buzzer 9 is stopped when the operation of the closing switch 42 is stopped.

Therefore, also in this case, it is possible to surely confirm that the sunroof 1 is closed to the fully closed position without relying on the naked eye.

As described above, in the sunroof opening / closing control device of this embodiment, the effects listed below can be obtained.

Since the non-fixed rear seat remote control switch 3 for the rear seat and the keyless remote control switch 4 for the exterior of the vehicle are provided, the sunroof 1 can be used indoors from any position of the three rows of seats S.
Since the opening / closing operation of the sunroof 1 can be performed and the opening / closing operation of the sunroof 1 can be performed from the outside of the vehicle, the usability is very high.

The rear seat remote control switch 3 can also be used in the front row seat S.

While providing two wireless opening / closing operation means of the rear seat remote control switch 3 and the keyless remote control switch 4,
According to the position of the ignition switch 7, it is determined whether the vehicle is in a boarding state or in a getting-off state, and the sunroof 1 is opened and closed only by the opening / closing operation of one of the remote control switches.
By operating 3, 4, there is no problem such as opening and closing different from the intended operation.

Moreover, when performing remote control from the inside of the vehicle, safety can be confirmed by the presence of an occupant, and when performing the history operation from outside the vehicle, it is in a disembarked state, ensuring safety in any case. be able to.

Since the determination of the getting-on state and the getting-off state is performed by the position of the ignition switch 7, the above-mentioned determination can be accurately made without adding a sensor or the like, and the cost can be reduced.

In the keyless controller 62 that is activated when the ignition switch 7 is an accessory or in the off position, a relay switch 625 is provided, and power is supplied to each of the limit switches 81 to 83 unless the keyless remote controller switch 4 is opened and closed. Therefore, even if any of the limit switches 81 to 83 is closed, it is possible to prevent the dark current from flowing when the engine is not driven and reduce the load on the battery B.

When the sunroof 1 is closed and slid, the buzzer 7 makes an intermittent sound (first alarm sound), and when the sunroof 1 is fully closed, the buzzer 7 switches to a continuous sound (second alarm sound). It is possible to accurately grasp the sliding state of the sunroof 1 when it is remotely operated from outside the vehicle, which makes it difficult to take a glimpse of the sliding state of No. 1.

In particular, it is effective as a means to know when it is not operating as intended due to device failure etc., and when compared with the one that notifies the full closure by stopping the intermittent sound when fully closed, the present invention Can be easily distinguished from the one in which the intermittent sound has stopped due to a failure, and the fully closed state can be reliably confirmed.

In addition, if there is an occupant, safety can be prompted by sound.

Although the embodiment has been described above with reference to the drawings, the specific configuration is not limited to this embodiment. For example, in this embodiment, the engine drives the determination of getting on and off of the ignition switch 7. I tried to do it depending on the position on the side where the engine is running or the position where the engine is stopped, but even if it is judged whether it is the position where the electrical equipment can be used or the position where the electrical equipment cannot be used, It is possible to judge the dismounting state with high accuracy. Specifically, the start position, the on position and the accessory position are set as the riding position,
The off position may be the exit position.

Further, in the embodiment, the rear seat remote control switch (vehicle compartment opening / closing operation means) 3 for remote control operation in the vehicle compartment is provided.
For the vehicle compartment, only the opening / closing operation means by wire may be used.

In the embodiment, as the vehicle exterior opening / closing operation means, a keyless remote control switch 4 for transmitting a radio signal by radio waves is used.
However, wireless signals different from radio waves such as infrared rays and sound waves may be used.

Further, although the limit switch is provided in the embodiment as the full-closed detecting means, other means such as a means for detecting full-closed when the motor is overloaded may be used.

(Effects of the Invention) As described above, in the sunroof opening / closing control device of the present invention, the vehicle exterior opening / closing operation means for transmitting a wireless opening / closing signal and the fully closed detection means for detecting the fully closed state of the sunroof are provided. , A buzzer for emitting the first and second alarm sounds,
Further, the actuator is driven based on a wireless opening / closing signal, and the buzzer emits a first alarm sound when the sunroof is closed and slid, and when the sunroof is fully closed, the buzzer sounds the first alarm. Since the control means for switching from the second to the second alarm sound is provided,
It is possible to open and close the sunroof by remote control from outside the vehicle, which has the effect of improving usability.
The buzzer is the first when sliding the sunroof closed.
When the sunroof sounds, the buzzer switches from the first alarm sound to the second alarm sound when the sunroof is fully closed. In addition to the effect that the closed slide and fully closed state of the sunroof can be surely confirmed, the effect that the person who is not performing the opening / closing operation can be alerted is also obtained. The sound is emitted not only when the slide is closed but also when the slide is fully closed.Therefore, the sound generated during the slide is silenced when the slide is fully closed. Thus, it is possible to obtain the effect that the fully closed state can be surely known.
