Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic door lock control device for locking or unlocking a door by remote control with a remote controller. The present invention relates to an automatic door lock control device that automatically locks when it is no longer locked.

[0002]

2. Description of the Related Art Conventionally, when a request switch provided on an outside handle on a vehicle side is depressed when getting off the vehicle, a loop-type dedicated antenna provided on an upper part of a door on a vehicle side or a side mirror and a card are incorporated in a card. The ID code is collated between the antennas, and if the codes match, another personal identification code is transmitted from the card to the vehicle. The one that activates the locking device is described in the Cedric Gloria New Car Manual, pages D-7 to P-13 (199).
(January 1, 2006) published as a card entry system.

In this system, a key is not inserted into a key switch, a driver's door is unlocked,
When the driver is in the area where the entry card can communicate and all the doors are closed, the driver can press the request switch on the outside handle of the driver's door to complete the operation. The door is locked.

[0004]

However, in this system, if the driver does not inadvertently press the request switch and the door is not locked, the vehicle may be left in an unlocked state. There is a risk of theft.

[0005] Further, since a card serving as a transceiver in this system does not have a manual switch for locking or unlocking, a door cannot be manually operated for locking and unlocking with only this card.

[0006] Further, since the portable transceiver is a card, it is separate from the vehicle key and is left behind.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and provides an automatic door lock control device which has a function of preventing an annoying operation when locking a door, has a function of preventing theft, and prevents a key from being left behind. Is a technical task.

[0008]

The technical means taken to solve the above-mentioned problem is to detect the state of the getting-off state detecting means, and when the getting-off state is reached, the control means communicates with the remote controller, The door is locked when there is no response from the remote control.

With the above arrangement, the control means communicates with the remote controller when the getting-off state is detected, and when the remote controller stops responding, that is, when the user carrying the remote controller leaves the vehicle at the time of getting off. Is detected and the door is automatically locked, so that the trouble of locking the door by operating a key or a switch at the time of getting off lock is eliminated.

[0010] Preferably, if the getting-off state is detected by using any one of an ignition switch, a key detection switch, and a door courtesy switch of the vehicle, it is not necessary to add an extra sensor for detecting the getting-off state. The judgment indicates that the getting off state is detected.

The control means may control the remote controller when the ignition switch is turned off, the key detection switch is turned off from the key cylinder, and the signal from the door courtesy switch changes from the open state to the closed state. Preferably, an ID request signal is transmitted.
By doing so, the getting-off state is accurately detected from the states of the ignition switch, the key detection switch, and the door courtesy switch. Further, when the getting-off state is detected, a request for transmitting an ID can be issued from the control means to the remote controller.

In this case, by transmitting an ID request signal from the control means by a weak radio wave, communication between the vehicle and the remote controller becomes possible only when the user is away from the vehicle and only when the user is still near the vehicle. Is unlocked, but the door is automatically locked when the vehicle is out of reach of radio waves, improving safety and preventing theft.

When the remote control receives the ID request signal from the control means, the remote control sends a unique registration ID to the control means.
Is transmitted, it is possible to determine whether the ID is from the determined user.

The control means controls the registration I transmitted from the remote controller.
D is pre-registered, and if the ID is a registered ID, communication with the remote controller is performed again, thereby allowing mutual communication only with signals from the remote controller registered for each vehicle. Becomes possible.

If the control means enters the power saving mode when communication is continuously performed from the remote controller for a predetermined time, the load on the battery is reduced.

Furthermore, if the remote control is integrated with the vehicle key or of a key holder type, the remote control can be prevented from being left behind.

5. The state of the DSW (door courtesy switch) 14 is detected. Here, the IG switch 13 is turned off (ignition is not turned on), the key unlock warning switch 15 is turned off (the vehicle key is not touching the key cylinder). ), It is determined whether the door courtesy switch 14 is on (the door is open).

If the condition of step S103 is satisfied (the door 1 is in the open state), the process proceeds to step S119.
If this condition is not satisfied, step S104
Execute

In step S104, the IG switch 13
Is turned off (the IG is not turned on), the key unlock warning switch 15 is turned off (the vehicle key is not touched), and the door courtesy switch 14 is turned off (the door is closed). If the condition is satisfied, step S105 is performed. If the condition is not satisfied, the process proceeds to step S118.

In step S105, it is determined whether an ID code has been received from the remote controller 10. If an ID code has been received, step S106 is performed. If no ID code has been received, the process proceeds to step S109. In the next step S106, it is determined whether the ID code from remote controller 10 is a registered ID registered in advance for each vehicle. If the received ID code is the registered ID of the vehicle, step S107 is performed,
If it is not D, that is, if it is not the ID of the own vehicle (if the ID is issued by something other than the remote control 10 of the own vehicle), the process proceeds to step S109. In step S107, the lock switch 10a of the remote controller 10 is operated, and it is determined whether a lock signal has been received. Here, the remote control 10
When the lock signal is received from the
Is locked, the door is locked in step S116, and the process proceeds to step S118. But,
If the lock signal has not been received in step S107, it is determined in step S108 whether an unlock signal has been received from the remote controller 10 this time. Here, if the unlock signal is received, it means that the user has issued an unlock request, and therefore, step S117 is performed.
Then, the door 1 is unlocked, and the process proceeds to step S118. After entering the sleep mode in step S118, the process returns to step S101 to repeat the same processing.

If the ID code has not been received in step S105, it is determined in step S109 whether the door handle switch 12 is turned on, that is, the door 1 is pulled. That is, when the outside handle 2 is not pulled, step S1 is executed.
18, the process proceeds to step S110. If the outside handle 2 is pulled, the remote controller 10
Transmit a D request signal.

Thereafter, in step S111, the remote controller 10
It is determined whether the ID code has been received from the server. If the ID code has not been received, the process proceeds to step S118.
If the ID code has been received, it is determined in step S112 whether the ID code is a registered ID registered in advance for each vehicle. If the received ID is not the registered ID of the own vehicle, the process proceeds to step S118. If the received ID is the registered ID of the own vehicle, it is determined in step S113 whether a response signal from the remote controller 10 has been received. You. Step S1
If no response signal is received in step 13, step S11
8 is performed, but if a response signal is received, step S
At 114, the door handle switch 12 is turned off, that is, until the outside handle 2 is returned, and then unlocked at step S115.

On the other hand, if the condition of step S103 is satisfied, a door courtesy state is detected in step S119, and it is determined that the door courtesy state is off, that is, whether the vehicle key is removed and the door 1 changes from the open state to the closed state. You. Here, if the state of the door 1 remains open, step S
When the door has changed from the open state to the closed state (when the exit state of the user has been detected), the process proceeds to step S118.
At 120, an ID request signal is transmitted to the remote controller 10.

After transmitting the ID request signal, it is determined in step S121 whether an ID code has been received from the remote controller 10. If the ID code has been received, step S122 is performed. If the ID code has not been received, step S122 is performed. Move to S130. In step S122, I
It is determined whether or not the D code is a registration ID.
If it is not D, the process proceeds to step S130, but the registration ID
If so, step S123 is performed. Step S1
At 23, it is determined whether a response signal has been received. If a response signal has been received, a predetermined time T3 (2 seconds) is waited for at step S124, and it is determined whether a predetermined time T1 (30 seconds) has elapsed at step S125. If the predetermined time T1 has not elapsed, the process returns to step S120 to repeat the process, but if the predetermined time T1 has elapsed, the process proceeds to step S118.

If no response signal is received in step S123, it is determined in step S126 whether a lock signal has been received. If a lock signal has been received, a lock request has been issued in step S127, so that the door 1 is locked. And the process moves to step S118. On the other hand, if the lock signal has not been received, it is determined whether an unlock signal has been received next. Here, when the unlock signal is received, the door 1 is unlocked in step S129 because an unlock request is issued from the user. Here, if the unlock signal is not received, after waiting for a predetermined time T2 (5 sec) in step S130, a process of locking the door 1 in step S131 is performed.

Next, the processing of the remote controller 10 will be described with reference to FIG.

The remote controller 10 is always in standby in the power saving mode (S201), and wakes up when a signal is sent from the control device 20 or when the operation switches 10a and 10b are operated. . That is, in step S202, it is determined whether there has been a key input from the lock switch 10a. If there is a key operation from the lock switch 10a, the process wakes up in step S203 and sends a lock signal to the control device 2 in step S204.
0 is transmitted by radio waves (a lock operation using a normal remote controller). Next, if there is no input by the lock key 10a, it is determined whether or not there is a key input of the unlock switch 10b, and if the unlock switch 10b is operated, the process proceeds to step S206 (unlocking by a normal remote control). Operation), when the key of the unlock switch 10b is not input, it is determined in step S208 whether an ID request from the control device 20 has been received. Here, if the ID request signal from the control device 20 has not been received, the process returns to step S201 without outputting a response signal. However, if the ID request signal has been received, the process proceeds to step S209 and proceeds to step S2.
The wake-up is performed at 09, and a response signal (registered ID signal) is transmitted to the control device 20 by radio waves at the next step S210.

From the above, the ignition switch 13, the door courtesy switch 14, the key detection switch 1
5 is detected from the state, and when the vehicle is in the state of getting off, an ID request signal is sent from the control device 20 to the remote controller 10.
When the remote control 10 receives this signal, the remote control 10 returns a registration ID to the control device 20 to perform communication. The control device 20 confirms the registration ID from the remote control 10 and performs communication. Again, when the response from the remote controller 10 does not return, the door 1 is automatically locked, so that there is no need to lock the door 1 when getting off the vehicle, and when the user leaves the vehicle. Even if the lock is forgotten, it is automatically locked, so that theft can be prevented.

Although the present invention has been described with reference to an embodiment, the present invention is not limited to this. Further, in this embodiment, the door 1 is automatically locked when the door 1 does not open even after a certain period of time has elapsed after unlocking. It is also possible to add functions.

The control device 20 is shifted to a special mode by a combination of switches, and a lock switch 10a and an unlock switch 10b provided on the remote controller 10 are provided.
It is also possible to make it possible to perform additional registration and deletion of the ID by the operation described above.

[0040]

According to the present invention, the state of the getting-off state detecting means is detected, the control means communicates with the remote control when the getting-off state is reached, and locks the door when there is no response from the remote control. By doing so, the control means communicates with the remote controller when the getting-off state is detected, and detects that the user carrying the remote controller has left the vehicle when there is no response from the remote controller, that is, when getting off. Since the door is automatically locked, the trouble of locking the door by operating a key or a switch when the vehicle gets off the vehicle is eliminated.

If the getting-off state is detected by using any one of an ignition switch, a key detection switch, and a door courtesy switch of the vehicle, the getting-off state can be easily determined without adding an extra sensor for detecting the getting-off state. The state is to be detected. When the ignition switch is in the off state, the key detection switch is in the state in which the vehicle key is removed from the key cylinder, and the signal from the door courtesy switch is changed from the open state to the closed state, the control means sends an ID request signal to the remote controller. Should be sent. With this configuration, the getting-off state is accurately detected from the states of the ignition switch, the key detection switch, and the door courtesy switch, and when the getting-off state is detected, the control unit can issue a request for transmitting an ID to the remote controller. .

In this case, by transmitting the ID request signal from the control means by a weak radio wave, communication between the vehicle and the remote controller becomes possible only when the user is away from the vehicle and only when the user is still near the vehicle. Is unlocked, but the door is automatically locked when the vehicle is out of reach of radio waves, improving safety and preventing vehicle theft.

When the remote control receives the ID request signal from the control means, the remote control sends a unique registration ID to the control means.
By transmitting the ID, it is possible to determine whether the ID is from the determined user, the control unit compares the registration ID transmitted from the remote control whether it is registered in advance,
If the ID is a registered ID, communication with the remote controller is performed again, thereby enabling mutual communication only with a signal from the remote controller registered for each vehicle.

If the control means is set to enter the power saving mode when communication is continuously performed from the remote controller for a predetermined time, the load on the battery can be reduced and the battery can be prevented from running out.

Further, if the remote control is integrated with the vehicle key or of a key holder type, the remote control can be prevented from being left behind.
