DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a slide roof control device for controlling opening and closing of a slide roof of a vehicle by driving a motor.

[Prior Art] Conventionally, a vehicle slide roof is opened and closed only when a push button type slide roof open / close switch is pressed in order to prevent human hands, head or foreign matter from being caught. It stops when you release your hand from the open / close switch.

FIG. 3 is an electric circuit diagram of a conventional slide roof control device, and FIG. 4 is a perspective view showing a slide roof SR of a vehicle.

In FIG. 3, a motor control circuit 2 for controlling a motor 1 for driving the slide roof SR to open and close is provided with a fuse 4 when an ignition switch 3 is turned on.
Power is supplied from the vehicle-mounted battery 5 via
When the slide roof open / close switch 6 is opened / closed, the common contact c and the open contact b are closed to rotate the motor 1 so that the slide roof SR is opened, while the slide roof open / close switch 6 is closed / opened. In the above, the common contact c and the closed contact a are closed to control the rotation of the motor 1 so that the slide roof SR is closed. When the driver releases the slide roof open / close switch 6, the common contact c of the slide roof open / close switch 6 does not contact either the closed contact a or the open contact b, so that the motor 1 stops rotating and the slide roof SR This is to stop the slide roof.

[Problems to be Solved by the Invention] In the above-mentioned conventional slide roof control device, the slide roof SR opens and closes only when the driver pushes the slide roof open / close switch 6. Since it stops when you release your hand, if it becomes necessary to close the slide roof SR urgently during driving, for example, when it rains, the driver will continue to press the slide roof open / close switch 6 with one hand while the other will Since there is a need to operate the steering wheel with the hands, there is a problem in terms of safe driving, and there is a problem that it feels a kind of annoyance.

Therefore, in the present invention, in the case where it is raining during traveling, for example, after the wiper switch is operated, the slide roof opening / closing switch 6 can be closed and operated by one-touch operation to automatically move the slide roof. It is a technical subject to solve the above-mentioned conventional problems by closing them.

[Means for Solving the Problem] The technical means for solving the above problem is a slide provided with a slide roof opening / closing switch for driving a motor when being pushed to open and close the slide roof of a vehicle. In the roof control device, when both the operation signal of the wiper switch operated when operating the wiper and the closing operation signal of the slide roof opening / closing switch are input, the closing operation signal is in an instantaneous output state. And a slide roof closing control circuit for driving and controlling the motor so as to continuously close the slide roof to a fully closed state, and when the motor is driven by the slide roof closing control circuit in a direction of closing the slide roof. And an alarm means for issuing an alarm.

[Operation] According to the slide roof control device having the above configuration, when rain, snow, or the like falls during the traveling of the vehicle, the driver turns on the wiper switch to output an operation signal from the wiper switch. When the slide roof open / close switch is momentarily closed, the slide roof close control circuit inputs both the operation signal from the wiper switch and the close operation signal from the slide roof open / close switch to fully close the slide roof. The motor is driven and controlled so as to be continuously closed to the state, and the alarm means issues an alarm.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows the entire electric circuit of the slide roof control device. The motor 1, the ignition switch 3, the fuse 4, the battery 5, and the slide roof opening / closing switch 6 in FIG. 1 are the same as those shown in the electric circuit of the slide roof control device described in the section of the related art. Therefore, the same numbers as those in FIG. 3 are attached.

As shown in FIG. 1, the slide roof control circuit SRC surrounded by a broken line is the same as the electric circuit of the conventional slide roof control device, in which the required power from the battery 5 is supplied while the ignition switch 3 is turned on. It is being supplied. Further, the connection point between the ignition switch 3 and the fuse 4 is connected to the terminal B of the wiper switch WS via the fuse 4A. Furthermore, it is connected to the diode D1 connected to the terminal +2 of the wiper switch WS (connected to the high speed operation terminal Hi of the wiper motor) and the terminal +1 of the wiper switch WS (connected to the low speed operation terminal Lo of the wiper motor). Each cathode of the diode D2 has a slide roof control circuit SR
It is connected to one input terminal (active high input terminal) of the 2-input gate 20 of C.

The open contact b of the slide roof opening / closing switch 6 is connected to one end of the coil 11A of the relay 11 of the slide roof control circuit SRC. The closed contact a of the slide roof open / close switch 6 has one input terminal of the two-input NOR gate 15 and the active row input terminal of the two-input gate 20.
It is connected to the set (S) terminal of the flip-flop 14. In addition, one input terminal of the two-input NOR gate 15 and the above-mentioned two
The active low input terminal of the input gate 20 and the set (S) terminal of the flip-flop 14 are pulled up by the resistor R4. The common contact c of the slide roof opening / closing switch 6 is connected to the zero volt line of the battery 5.

The limit switch LS is mounted so that it is turned off (the contact is opened) when the slide roof SR is closed up to, for example, 100 mm before the fully closed position, and one end of the contact is connected to the zero volt line of the battery 5. At the same time, the other end of the contact is connected to the input terminal of the one-shot circuit 13. The input terminal of the one-shot circuit 13 is
It is pulled up by the resistor R5, and when the limit switch LS is turned off, one pulse is output from the one-shot circuit 13 to reset the flip-flop 14 (R).
It is designed to be input to the terminal. flip flop
14 output terminals (Q bar terminal) are 2 inputs NOR gate 15 1
It is connected to the input terminal, and the output terminal of the 2-input NOR gate 15 is connected to the 1-input terminal of the 2-input OR gate 16.

When the slide roof open / close switch 6 is operated to the closed contact a side, the flip-flop 14 causes the set (S) terminal to be logic “L” and the limit switch LS.
In the closed state, the output signal of the one-shot circuit 13 is logic "L", and the reset (R) terminal of the flip-flop 14 is logic "L". Therefore, the logic signal at the output terminal (Q-bar terminal) of the flip-flop 14 is in the previous state, that is, the logic "L" and does not change. for that reason,
The output signal of the 2-input NOR gate 15 becomes logic "H", and 2
The output terminal of the input OR gate 16 becomes logic "H", and 2
The transistor Tr1 connected to the output terminal of the input OR gate 16 via the resistor R7 is switched on. When the transistor Tr1 is switched on, the transistor T
The coil 12A of the relay 12 connected to the collector of r1 is excited. When the coil 12A of the relay 12 is excited, the contacts c and b of the relay 12 are connected, and the motor 1 rotates so as to close the slide roof SR. On the other hand, when the slide roof open / close switch 6 is operated to the open contact b side, an exciting current is applied to the coil 11A of the relay 11 and the contacts c and b of the relay 11 are connected, so that the motor 1 is operated by the slide roof SR. Rotate to open.

When a drive current is passed through the motor 1 to open / close the slide roof SR, a voltage drop occurs in the resistor R1. The comparator circuit including the operational amplifier 17, the operational amplifier 18, and the two-input NAND gate 19 is configured to detect the voltage drop of the resistor R1, one end of the resistor R1, the inverting terminal of the operational amplifier 17, and the non-inverting of the operational amplifier 18. It is connected to the terminal. In the operational amplifier 17, the voltage of the battery 5 is applied to the non-inverting terminal with the voltage divided by the resistors R2 and R3 as a reference voltage, and if the voltage drop of the resistor R1 is larger than this reference voltage, that is, the slide roof SR is When the motor 1 is slid to the fully open or fully closed state, or when a foreign object is caught in the process of closing, an excessive current is applied to the motor 1, so that the voltage drop of the resistor R1 becomes large and the operational amplifier 17 causes the logic "L". Signal is output. On the other hand, the operational amplifier 18
If the reference voltage of mV is applied to the inverting terminal and the voltage drop of the resistor R1 is smaller than this reference voltage, a signal of logic "L" is output from the output terminal. When a logical "L" signal is output from the operational amplifier 17 or the operational amplifier 18, the 2-input NAND gate 19 outputs a logical "H" signal, and the flip-flop 21 connected to the output terminal of the 2-input NAND gate 19 is reset. The flip-flop 21 is reset by applying a signal of logic "H" to the terminal (R).

The set (S) terminal of the flip-flop 21 is connected to the output terminal of the 2-input gate 20, and when the output terminal of the 2-input gate 20 becomes logic "H", the flip-flop 21 is set and the flip-flop 21 is set. A signal of logic "H" is output from the output terminal Q of the amplifier 21. The output terminal (Q terminal) of the flip-flop 21 is the 2-input OR gate 16
If the output terminal of the flip-flop 21 is logic "H", it is connected to the 1 input terminal of
The output signal of 16 becomes a logic "H", so that the transistor Tr1 is switched on to energize the relay 12 and rotate the motor 1 so that the slide roof SR closes.

The output terminal (Q terminal) of the flip-flop 21 is connected to the base of the transistor Tr2 via the resistor R6. The transistor Tr2 is the Q of the flip-flop 21.
When the output terminal becomes logic "H", the switching is turned on and the buzzer Bz is activated.

In the electric circuit configured as described above, when the ignition switch 3 is turned on, the voltage of the battery 5 is applied to the slide roof control circuit SRC via the fuse 4. Therefore, for example, when it suddenly rains during traveling, as shown in the timing chart of FIG. 2, the slide roof opening / closing switch 6 is momentarily operated while the wiper switch WS is turned on and the wiper is operated. When it is turned to the closed contact a side, the active low input terminal of the 2-input gate 20 becomes the logic “L”, while the logic “H” signal from the wiper switch WS is applied to the active high input terminal of the 2-input gate 20. Therefore, 2 input gate 20
Output becomes a logic "H", and the flip-flop 21 is set. As a result, even if the driver releases his hand from the slide roof opening / closing switch 6, the flip-flop 21
Since the same state as when the slide roof open / close switch 6 is continuously operated to the closed contact side, the flip flop
A logical "H" signal is continuously output from the 21 Q output terminals. Two-input OR gate 16 to which the logical "H" signal is input
Switches on the transistor Tr1 to activate the relay 12 and, as shown in FIG.
Rotate so that the slide roof SR closes.

Also, as the motor 1 rotates, the transistor Tr2 to which the logical "H" signal from the Q output terminal of the flip-flop 21 is applied via the resistor R6 is switched on, and the buzzer Bz sounds as shown in FIG. Therefore, the occupant of the vehicle is informed that the slide roof SR is sliding to be closed, and the occupant's hands and head are prevented from being caught.

When the slide roof SR is slid so as to be closed by the rotation of the motor 1 and is slid to the fully closed position, the current flowing through the motor 1 is increased and the voltage drop of the resistor R1 is increased. The signal becomes logic "L", and the signal of logic "H" is output from the 2-input NAND gate 19 to the reset terminal of the flip-flop 21. As a result, the flip-flop 21 is in the reset state, and the Q output terminal of the flip-flop 21 becomes the logic "L". Further, since one of the two input terminals of the 2-input NOR gate 15 is logic “H”, the output terminal of the 2-input NOR gate 15 becomes logic “L”, and the two input signals of the 2-input OR gate 16 are both logic “H”. It becomes "L". As a result, the output signal of the 2-input OR gate 16 becomes a logic "L" to switch off the transistor Tr1 and stop supplying the drive current to the motor 1.

As described above, when it suddenly rains during traveling, when the wiper switch WS is operated to operate the wiper, the slide roof SR is simply momentarily pressed. The driver can concentrate on the steering wheel operation because it can be closed.

On the other hand, if the slide roof open / close switch 6 is operated to the closed contact a side without operating the wiper, one of the input terminals of the 2-input NOR gate 15 becomes logic "L", and the flip-flop 14 turns the slide roof open / close switch 6 Since it is in the set state before it is operated to the closed contact a side, a signal of logic "L" is output from the Q bar output terminal, and the other input terminal of the 2-input NOR gate 15 is also logic "L".
become. Therefore, since the output terminal of the 2-input NOR gate 15 becomes the logic "H", the output of the 2-input OR gate 16 becomes the logic "H" and the transistor Tr1 is switched on. As a result, the motor 1 rotates so as to close the slide roof SR. The limit switch LS opens when the slide roof SR is closed and the end reaches 100 mm before full closing. Therefore, the signal applied to the input terminal of the one-shot circuit 13 changes from logic “L” to logic “H”. The one-shot circuit 13 outputs a one-pulse signal, and the flip-flop 14 is reset. Therefore, the Q-bar output signal of the flip-flop 14 becomes logic "H", and 2
Since the signal of logic "H" is applied to one of the input terminals of the input NOR gate 15, the output signal of the 2-input NOR gate 15 becomes logic "L" and the output of the 2-input OR gate 16 becomes logic "L". The transistor Tr1 is turned off to stop the rotation of the motor 1.

In the above state, the driver opens the slide roof open / close switch 6
When the driver releases the hand, the flip-flop 14 is set again. Therefore, when the driver operates the slide roof open / close switch 6 to the closed contact a side again, the slide roof SR slides from 100 mm before the full close by the same action as described above. Start and slide to the fully closed position.

[Advantage of the Invention] As described above, according to the present invention, when the vehicle is running, for example, when it rains, the driver operates the wiper to operate the slide roof opening / closing switch by one-touch operation. The sliding roof can be automatically closed to the fully closed position, and an alarm is generated when the sliding roof is sliding in the closing direction to prevent the hands and head of the vehicle occupant from being caught. Therefore, the driver can concentrate on the steering wheel operation, and there is an effect that traveling safety can be secured.
