  On the other hand, recently, in addition to the central door lock switch arranged around the driver's seat, even when the power slide door is closed after pressing the lock knob of the power slide door, Vehicles equipped with a sliding door side central locking system configured to complete door locking are offered to the market.

  However, the above-mentioned problem has not been solved in a conventional vehicle in which such a sliding door side central locking system is not mounted. In other words, the central door lock operation using the remote control key, intelligent key or smart key (hereinafter referred to as intelligent key) can be performed only after all the doors are completely closed. There wasn't.

  The present invention was devised to solve such problems, and the purpose thereof is a conventional vehicle (particularly, a power slide door equipped vehicle) in which the above-described sliding door side central locking system is not mounted. Connection that can automatically lock all doors after all doors are closed by using the door lock switch of the conventional remote control key or the conventional intelligent key as it is and performing the door lock operation in advance. It is to provide a switching device.

  In order to solve the above problems, a connection switching device according to the present invention is connected between a door detection means provided on a vehicle body side that detects opening and closing of a vehicle door and a control means of the vehicle. A connection switching device for switching the connection of the signal line between the control means, comprising a trigger switch for outputting a trigger signal, and a switching means for switching the connection between the door detection means and the control means; When the trigger switch is operated, the switching unit disconnects the signal line between the door detection unit and the control unit, and pseudo-closes the signal line on the control unit side, When the door detection means detects the closed state of the door, the signal line between the door detection means and the control means is connected again.

  In the centralized door lock control by the centralized door lock operation by the conventional remote control key or intelligent key etc., the open / closed state of the door is based on the detection signal of the door detection means that detects the opening / closing of each door provided on the vehicle body side. Is going. That is, while receiving an open state detection signal (specifically, a 0 V signal that is a ground potential described later) indicating that the door is open from the door detection means, a centralized door using a remote control key, an intelligent key, or the like. Even if the lock operation is performed, the door lock control is not performed.

  Therefore, in the present invention, paying attention to this point, even when the door is in an open state, by operating the trigger switch, a pseudo-close state signal (specifically, an open state) indicating the door is closed. The power supply 12V signal) is output to the vehicle-side control means. As a result, the vehicle side control means normally accepts the subsequent key operation, that is, the operation of the concentrated door lock by the remote control key or the intelligent key. As a result, even if the user performs a centralized door lock operation using a remote control key or intelligent key while the power slide door is open, the slide door is included when the power slide door is closed even if the user moves away from the vehicle. All doors will be locked completely.

  Further, according to the connection switching device of the present invention, the switching means includes a detection unit that detects an open / closed state of the door detection means, and a connection state and a disconnection state between the door detection means and the control means. A switching unit that switches to one of these states and a control unit that controls switching of the switching unit are provided. The switching unit is configured by a relay circuit.

  The connection switching device according to the present invention further comprises an ignition signal detecting means for detecting an ignition signal from a vehicle, wherein the switching means detects the ignition signal indicating the engine drive state by the ignition signal detecting means. If it is, the operation of the trigger switch is invalidated. According to the above configuration, malfunction during traveling can be prevented.

  Further, according to the connection switching device of the present invention, an output means for outputting a driving state pseudo signal indicating an engine driving state to a security device mounted on the vehicle, a lock signal from the vehicle, or the security device A lock detection unit that detects a lock signal from the output unit, and the switching unit detects the lock signal after the trigger switch is operated, and after the predetermined time elapses, The driving state pseudo signal may be output to the security device, and when the door detection unit detects the closed state of the door, the output of the driving state pseudo signal from the output unit may be stopped.

  With such a configuration, even if the vehicle is equipped with a security device, the security device can be operated normally after all the doors are automatically locked without causing the security device to malfunction. That is, after the trigger switch is operated, when the lock detection unit detects the lock signal by the operation of the centralized door lock, the output unit sends the security device to the security device after a predetermined time (for example, 5 seconds). To output a driving state pseudo signal. On the other hand, the security device also receives the lock signal and sets the security operation. The security device starts the security operation after elapse of a certain time (for example, 10 seconds, 30 seconds, etc.) in accordance with the processing operation set in the own device. Since the signal is output, the security device shifts to the standby state before starting the security operation in response to the driving state pseudo signal. Thereby, it is possible to prevent malfunction of the security device.

  Thereafter, when the sliding door is closed and the concentrated door lock is completed, the output of the drive state pseudo signal from the output means is stopped, and accordingly, the security device shifts from the standby state to the security operation state. That is, thereafter, the security operation is started as usual.

  Since the present invention is configured as described above, even with a conventional power slide door mounted vehicle, the central door lock is operated by operating the remote control key or the intelligent key while the power slide door is open, And even if it performs operation which closes a slide door and leaves | separates from a vehicle, all the doors including a power slide door can be completely locked in the step which a power slide door closed.

  FIG. 2 shows an example of a circuit configuration of the connection switching device A connected as described above. Hereinafter, the circuit configuration of the connection switching device A according to the first embodiment (internal circuit configuration of the main unit 10) will be described with reference to FIG.

  The connection switching device A according to the first embodiment is broadly divided between the main control unit 11, the trigger switch 12 connected to the main control unit 11, and the divided signal lines of the signal lines 1 and 2. The relay control unit 13 for switching and controlling the relay circuit 13a, the right door open / close detection unit 14 connected to the divided first signal line 1b of the right sliding door switch 200a, and the divided first signal line 2b of the left sliding door switch 200b. The left door opening / closing detection unit 15 connected to the IG, and the IG signal detection unit 16 for detecting the operation signal of the ignition switch (IG), the relay control unit 13, the right door opening / closing detection unit 14, the left door opening / closing The detection unit 15 and the IG signal detection unit 16 are each connected to the main control unit 11.

  Next, a processing operation when the connection switching device A having the above-described configuration is applied to the central door lock processing will be described.

  As described above, in the conventional vehicle, the central door lock control by the operation of the central door lock using the remote control key or the intelligent key is performed by changing the door open / closed state to the right slide door switch 200a provided on the vehicle body side and the left slide. This is performed based on a detection signal from the door switch 200b. That is, while receiving the door open state detection signal indicating that the door is open from the right slide door switch 200a and the left slide door switch 200b, the central door lock operation is performed using the remote control key or the intelligent key. Even so, the central door lock control is not performed. Even if the above-mentioned centralized door lock operation is performed with the door open, even if the door is closed at that time, all the doors are unlocked when the door is closed. It has become.

  Here, the right slide door switch 200a and the left slide door switch 200b connect the first signal line 1 and the second signal line 2 to the ground potential (0 V potential) when the slide door is open, When fully closed, the switch is separated from the ground potential and is in an open state (power supply 12V potential). The computer 100 slides while receiving a 0V signal (door open state detection signal) indicating the ground potential. When it recognizes that the door is open and receives a 12V signal (door closed state detection signal) indicating the open state of the right slide door switch 200a and the left slide door switch 200b, it recognizes that each slide door is completely closed. It is like that.

  Therefore, in the connection switching device A of the first embodiment, even when the trigger switch 12 is provided and the door is open, when the central door lock operation is performed by the remote control key or the intelligent key, etc. , Devised to be able to perform centralized door lock.

  That is, in the normal state where the trigger switch 12 is not operated in the connection switching device A of the first embodiment, the common terminals 21c and 22c are connected to the other switching terminal 21b and the relay switches 21 and 22 of the relay circuit 13a. 22b side is connected. That is, this is the same as the connection state of a signal line of a conventional vehicle not connected to the connection switching device A, and the computer 100 receives signals from the left and right sliding door switches 21 and 22 (door open state detection signal ( 0V signal) or door closed state detection signal (12V signal). Here, a case where a door open state detection signal (0 V signal) is input will be described.

  In this state, when the trigger switch 12 is pressed, the main control unit 11 that has received the ON signal of the trigger switch 12 controls the relay control unit 13 to connect the relay switches 21 and 22 of the relay circuit 13. The other connection terminals 21b and 22b are switched to the one connection terminal 21a and 22a side. That is, the common terminals 21c and 22c are connected to the other connection terminals 21a and 22a in the open state (12 V potential).

  That is, by switching the connection of the relay switches 21 and 22 of the relay circuit 13a from the one connection terminal 21a, 22a (0V or 12V) side to the other connection terminal 21a, 22a (12V) side, the sliding door is completely This creates a state in which the computer 100 recognizes that it is closed. That is, even when the slide door is in an open state, pressing the trigger switch 12 creates a state in which it is recognized that the slide door is closed in a pseudo manner.

  Thereby, the user then performs an operation of closing the slide door (specifically, an operation of closing the slide door by pulling a knob of the slide door), and then performing a central door lock operation using a remote control key, an intelligent key, or the like. Then, the sliding door starts to be closed while being locked, and the locked state is maintained even after the sliding door is closed.

  Therefore, the user operates the trigger switch 12 after getting off the vehicle, and then performs the operation of closing the sliding door and the lock operation in this order or in the reverse order, so that the user can leave the vehicle. Even after the sliding doors are closed, all the doors can be completely locked. In other words, the central door can be locked using a conventional remote control key, intelligent key, or the like in a conventional vehicle without having to wait on the spot until the slide door is closed.

  Thereafter, when the right slide door 200a and / or the left slide door 200b are actually closed and the right slide door switch 200a and / or the left slide door switch 200b are turned off, the divided first signal lines 1b and 2b are connected to the ground potential (0 V). To open state (12V). When the open state (12V) is detected by the right door opening / closing detection unit 14 and / or the left door opening / closing detection unit 15, the right door opening / closing detection unit 14 and / or the left door opening / closing detection unit 15 is connected to the main control unit 11. A door closed state signal (for example, 5V signal) indicating that the slide door is actually closed is output. When the main controller 11 confirms that both the right slide door and the left slide door are actually closed by receiving the door close state signal from both the right door open / close detector 14 and the left door open / close detector 15, The relay control unit 13 is controlled to switch the connection of the relay switches 21 and 22 of the relay circuit 13 from one connection terminal 21a or 22a to the other connection terminal 21b or 22b. That is, it returns to the connection state of the signal line of the conventional vehicle to which the connection switching device A is not connected. As a result, various remote control operations by conventional vehicles can be performed as usual.

  In addition, even if the signal which shows that the main control part 11 has detected the ignition signal which shows an engine drive state from the IG signal detection part 16 is input even if the trigger switch 12 is pushed, Treat the operation as invalid. That is, the above processing operation is not executed. Thereby, it is possible to prevent malfunctions during traveling.

<Embodiment 2>
FIG. 3 is a connection configuration diagram of the connection switching device B according to the second embodiment of the present invention, and FIG. 4 is a circuit configuration diagram of the connection switching device B.

  The connection switching device B of the second embodiment enables the operation of the central door lock while preventing the security device from malfunctioning when the security device is mounted on the vehicle. Therefore, in addition to the configuration of the connection switching device A of the first embodiment, the connection switching device B of the second embodiment outputs a pseudo IG signal that indicates an engine driving state to the security device 300 mounted on the vehicle. An IG signal output unit 17 and a lock detection unit 18 that detects a lock signal from the computer 100 of the vehicle or a lock signal from the security device 300 are further provided.

  Next, processing operations when the connection switching device B having the above-described configuration is applied to the centralized door lock processing will be described.

  That is, in the normal state where the trigger switch 12 is not operated in the connection switching device B of the second embodiment, the relay terminals 21 and 22 of the relay circuit 13a have the common terminals 21c and 22c as the other switching terminals 21b and 21b, respectively. 22b side is connected. That is, this is the same as the connection state of a signal line of a conventional vehicle not connected to the connection switching device A, and the computer 100 receives signals from the left and right sliding door switches 21 and 22 (door open state detection signal ( 0V signal) or door closed state detection signal (12V signal). Here, a case where a door open state detection signal (0 V signal) is input will be described.

  In this state, when the trigger switch 12 is pressed, the main control unit 11 that has received the ON signal of the trigger switch 12 controls the relay control unit 13 to connect the relay switches 21 and 22 of the relay circuit 13. The other connection terminals 21b and 22b are switched to the one connection terminal 21a and 22a side. That is, the common terminals 21c and 22c are connected to the other connection terminals 21a and 22a in the open state. As a result, even when the slide door is open, pressing the trigger switch 12 can create a state in which it is recognized that the slide door is closed in a pseudo manner.

  Therefore, after that, when the user performs an operation of closing the slide door (specifically, an operation of closing the slide door by pulling a knob of the slide door), and then performing a central door lock operation using a remote control key, an intelligent key, or the like. The sliding door starts to be closed while being locked, and the locked state is maintained even after the sliding door is closed.

  Thereafter, when the right slide door 200a and / or the left slide door 200b are closed and the right slide door switch 200a and / or the left slide door switch 200b are turned off, the divided first signal lines 1b and 2b are opened from the ground potential (0 V). It will be in a state (12V). When the open state (12V) is detected by the right door opening / closing detection unit 14 and / or the left door opening / closing detection unit 15, the right door opening / closing detection unit 14 and / or the left door opening / closing detection unit 15 is connected to the main control unit 11. A door closed state signal (for example, 5V signal) indicating that the slide door is actually closed is output. When the main controller 11 confirms that both the right slide door and the left slide door are actually closed by receiving the door close state signal from both the right door open / close detector 14 and the left door open / close detector 15, The relay control unit 13 is controlled to switch the connection of the relay switches 21 and 22 of the relay circuit 13 from one connection terminal 21a or 22a to the other connection terminal 21b or 22b. That is, the connection state of the signal line of the conventional vehicle to which the connection switching device B is not connected is restored. As a result, various remote control operations by conventional vehicles can be performed as usual.

  Further, when receiving the door closed state signal from both the right door opening / closing detection unit 14 and the left door opening / closing detection unit 15, the main control unit 11 stops outputting the pseudo IG signal from the pseudo IG signal output unit 17. Thereby, thereafter, the security device 300 starts the security operation according to the processing operation set in the own device.

  On the other hand, the main control unit 11 also performs processing for the security device 300 in parallel with the processing operation of the central door lock. That is, when the lock detection unit 18 detects a lock signal by the operation of the central door lock after the trigger switch 12 is operated, the main control unit 11 has passed a predetermined time (for example, 5 seconds). Later, the pseudo IG signal output unit 17 outputs a pseudo IG signal to the security device 300. On the other hand, the security device also receives the lock signal from the vehicle computer 100 and sets the security operation. This set of security operations is performed during the predetermined time. Thereafter, the security device 300 starts the security operation after elapse of a certain time (for example, 10 seconds or 30 seconds longer than the predetermined time) according to the processing operation set in the own device. When the time elapses, a pseudo IG signal is output from the pseudo IG signal output unit 17, so that the security device 300 shifts to a standby state before receiving the pseudo IG signal and starting a security operation. Thereafter, when the sliding door is completely closed and the central door lock is completed, the pseudo IG signal output from the pseudo IG signal output unit 17 is stopped, so that the security device 300 receives the security signal from the standby state. Transition to the operating state. That is, thereafter, the security operation is started as usual.

  According to the connection switching device B according to the second embodiment, even a vehicle equipped with the security device 300 can automatically lock all the doors without causing the security device 300 to malfunction. That is, the security device can be activated after all doors are automatically locked.

  In addition, even if the signal which shows that the main control part 11 has detected the ignition signal which shows an engine drive state from the IG signal detection part 16 is input even if the trigger switch 12 is pushed, Treat the operation as invalid. That is, the above processing operation is not executed. Thereby, it is possible to prevent malfunctions during traveling.

  In the above embodiment, the connection switching device of the present invention is described as a configuration in which only the signal line of the door detection means of the power slide door is connected. However, the door detection of the hinged door structure of the driver seat and the passenger seat is performed. The signal switching line of the present invention and the signal line of the door detection means for the rear door of the flip-up type intervene the connection switching device according to the present invention, so that not only the sliding door but also other doors are opened. Even when the switch is pressed, the central door can be locked. The connection switching device of the present invention can be applied to, for example, a garage automatic shutter device in addition to a vehicle.
