Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunroof opening / closing control device capable of automatically opening / closing a sunroof.

(Prior Art) As a conventional sunroof opening / closing control device, Nissan Service Weekly Report No. 563 NISSAN Caravan Homey
The ones disclosed on pages D-15 and 16 of the introduction of E24 series cars (published: September 1986, published by Nissan Motor Co., Ltd.) are known.

In this conventional technique, a sunroof is provided so as to be opened and closed by driving an actuator, and a control circuit for performing drive control of the actuator is provided. The control circuit is a front sunroof switch provided near a driver's seat such as a dash panel, The drive control is performed based on the operation of the rear sunroof switch provided on the side panel or the like of the rear seat.

(Problems to be Solved by the Invention) However, in this conventional technique, the opening / closing operation cannot be performed from outside the vehicle. For example, when the occupant notices that he / she got out of the vehicle and forgot to close the sunroof, It is inconvenient to enter the passenger compartment again and operate the ignition switch and either the front or rear switch to close it, and it is inconvenient if the vehicle is parked for a long time on a hot summer day. If the temperature becomes high, the vehicle opening including the sunroof may be opened and air may be exchanged before boarding the vehicle. It is inconvenient to operate.

Therefore, it is conceivable that remote control can be performed from outside the vehicle by using a so-called remote control switch that wirelessly transmits an opening / closing signal.

In this case, since it is operated from outside the vehicle, remote control is not always performed from a position where the open / closed state of the sunroof can be grasped.Therefore, a limit switch for detecting the position of the sunroof must be provided, and as a matter of course, the ignition switch is used. It is not useful unless it is switched off and the engine is stopped.

However, in this way, when the ignition switch is turned off and the engine is stopped and control is possible even when the generator is not generating power, if the limit switch is closed, dark current will continue to flow in this circuit, and the battery will continue to flow. There is a problem of burdening.

The present invention has been made in view of the above-mentioned problems, and makes it possible to open and close the sunroof from the outside of the vehicle by remote control, and to prevent the dark current from flowing even when the limit switch is closed, thus reducing the burden on the battery. An object of the present invention is to provide a sunroof opening / closing control device that can be made lighter.

(Means for Solving the Problem) According to the present invention, the control means sets the limit switch to the non-energizable state when not receiving the wireless open / close signal, and the state in which the limit switch can be energized when the wireless open / close signal is received. It was decided to solve the above problem by providing a power supply switching means.

That is, in the sunroof opening / closing control device of the present invention, a sunroof that opens and closes based on the drive of an actuator is provided on a vehicle body, and a limit switch that opens and closes according to the position of the sunroof is provided, and an exterior opening / closing operation for transmitting a wireless opening / closing signal. Means for controlling the drive of the actuator based on the wireless opening / closing signal and the open / closed state of the limit switch, and energizing the limit switch when the controller does not receive the wireless opening / closing signal. The power supply switching means is provided so that the limit switch can be energized when the wireless switching signal is received.

(Operation) When the opening / closing operation means for outside the vehicle is not opened / closed, the control means does not receive the wireless opening / closing signal, so that the power supply switching means sets the limit switch to the non-energizable state.

Therefore, depending on the position of the sunroof, even if the limit switch is closed, dark current does not flow in the circuit that has this limit switch, and even if the engine is not running and the generator is not generating power, the battery is burdened. There is no need to pay.

On the other hand, when an opening / closing operation is performed by the outside vehicle opening / closing operation means, a wireless opening / closing signal is transmitted from the outside vehicle opening / closing operation means,
Upon receipt of this, the control means drives the actuator on the basis of this wireless opening / closing signal to open / close the sunroof, and at the same time, the power supply switching means brings the limit switch into an energizable state.

Therefore, it is possible to perform control according to the position of the sunroof based on the change in the electric signal accompanying the opening and closing of the limit switch.

On the other hand, in step 103, the keyless remote controller 62 is activated, and the process proceeds to the next opening / closing and buzzer control 300 by the keyless controller 62, and then returns to step 101.

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 41.
Whether the switch is the closed switch 42 or the closed switch 42 is determined. If the switch is the open switch 41, the process proceeds to step 304, and 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, the process proceeds 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 the intermediate switch 83 is in the closed state. If YES, the process proceeds to step 310 and NO
If so, proceed 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. If YES, the process proceeds to step 313, and if NO, the process proceeds to step 314.

In step 313 on the YES side, the closing drive of the motor 2 is stopped and the continuous sound is generated by the buzzer 9, and the process proceeds to step 315.

In step 315, it is determined whether or not the operation of the closing switch 42 is stopped. If NO, the process returns to step 313, and if YES, the process proceeds to step 316.

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 opening / closing operation of the sunroof 1 is performed by the rear seat remote controller switch 3 and the front opening / closing switch 5.

Therefore, when the engine is driven in this way, the sunroof 1 is not opened or closed even if the keyless remote control switch 4 is operated to open or close it.

(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 opening / closing control of the sunroof 1 can be performed only by the keyless remote control switch 4.

Next, the operation of opening and closing the sunroof 1 will be described by taking the case of operating the keyless remote control switch 4 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 is performed, the buzzer 9 emits an intermittent sound.

Therefore, it is possible to confirm that the sunroof 1 is closed and slid even when the sunroof 1 is not visible outside the vehicle.

Then, when the sunroof 1 slides to a position 250 mm 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 is turned on again.
Generates an intermittent sound, and the motor 2 is driven to close, so that the sunroof 1 is closed and slid.

After that, when the front-close limit switch 82 is opened, the closing drive of the motor 2 is stopped, and the buzzer 9 switches to a continuous 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 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 remote control is performed from inside the vehicle, safety can be confirmed by the presence of an occupant, and when remote control is performed from outside the vehicle, the vehicle is in a dismounted 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 sliding closed, the buzzer 7 makes an intermittent sound, and when it is fully closed, it switches to a continuous sound. Moreover, it is possible to accurately grasp the sliding state of the sunroof 1.

In particular, it is effective to be able to know when an operation is not performed as intended due to a device failure or the like.

In addition, it is possible to improve safety by sound when an occupant is present.

Although the embodiment has been described above with reference to the drawings, the specific configuration is not limited to this embodiment.
In the present embodiment, the ignition switch 7 is used to determine whether the passenger is getting on or off the vehicle, depending on whether the engine is on the side where the engine is driving or the side where the engine is off. It is possible to judge the riding / unloading status with high accuracy even if it is judged based on the position where the electrical equipment cannot be used. Specifically, the start position, the on position and the accessory position are the riding position. The off position may be set as the exit position.

Further, in the embodiment, the rear seat remote control switch (vehicle compartment opening / closing operation means) 3 that sends out a wireless signal by infrared rays is used, and the keyless remote control switch (outside vehicle opening / closing operation means) 4 sends out a wireless signal by radio waves. However, the combination of infrared rays and radio waves may be reversed, only one of them may be used, or a wireless signal such as a sound wave other than these 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 the wireless opening / closing signal is provided, and the above-mentioned operation is performed based on the opening / closing state of the wireless opening / closing signal and the limit switch. A control means for controlling the drive of the actuator is provided, and when a wireless opening / closing signal is not received,
Since the control means is provided with a power supply switching means for setting the limit switch in the non-energizable state and for setting the limit switch in the energizable state when a wireless opening / closing signal is received, the sunroof can be remotely operated from outside the vehicle. The effect is that it can be opened and closed, improving usability.In addition, power will be supplied to the limit switch only when a wireless open / close signal is transmitted from the exterior opening / closing operation means, and the engine will be stopped to generate electricity. It is possible to prevent the dark current from flowing to the limit switch unnecessarily when the power generator is not generating power, and to reduce the burden on the battery.
