It is configured with.
[0018]
The transmission / reception circuit 3 includes an antenna 7 formed of a coil. When the activation trigger signal is given from the control circuit 6, the transmission / reception circuit 3 transmits the activation trigger signal from the antenna 7 as an air propagation signal (for example, a magnetic signal). . In this case, as shown in FIG. 2, the antenna 7 is incorporated in the door mirror 8 on the driver's seat side of the vehicle 2, so that the activation trigger signal is transmitted to the vicinity of the driver's seat side door 9. It has become. That is, the range indicated by A in FIG. 2 is the communication area. The transmission / reception circuit 3 outputs the received ID code to the control circuit 6 when receiving the ID code transmitted from the portable device 10 described later in detail by the antenna 7.
[0019]
The door opening / closing detection switch 4 detects the opening / closing of the driver's seat side door 9 (see FIG. 2), and outputs the door opening detection signal to the control circuit 6 when the opening of the driver's seat side door 9 is detected. On the other hand, when the closing of the driver's seat side door 9 is detected, a door closing detection signal is output to the control circuit 6. In FIG. 1, switches for detecting opening and closing of the passenger seat door 11, the rear right seat door 12, the rear left seat door 13 and the back door 14 (see FIG. 2) of the vehicle 2 are omitted. Yes.
[0020]
The door lock control device 5 is supplied with a lock command signal and an unlock command signal from the control circuit 6. When the door lock control device 5 is given a lock command signal, the door lock control device 5 controls the unlocked door of the doors 9 and 11 to 14 in the vehicle 2 to the locked state. The locked door is held in the locked state. On the other hand, when the unlock command signal is given, the locked door is controlled to the unlocked state and unlocked. The door which is made to be locked is held in an unlocked state.
[0021]
The control circuit 6 is composed mainly of a microcomputer, and outputs a start trigger signal to the transmission / reception circuit 3 as described above by executing a stored program, and the door opening / closing detection switch 4. When a door opening detection signal or a door closing detection signal is given from, predetermined processing is executed. Further, when the ID code is given from the transmission / reception circuit 3 as described above, the control circuit 6 determines whether or not the given ID code matches the stored code stored in itself. It has become. Further, the control circuit 6 has a counter function.
[0022]
As shown in FIG. 3, the portable device 10 described above includes, for example, an ignition key, and includes an input circuit 15, a transmission / reception circuit 16, and a control circuit 17. The input circuit 15 is configured to output an operation detection signal to the control circuit 17 in response to an operation switch 19 (see FIG. 3) disposed in the key grip portion 18 being operated.
[0023]
The transmission / reception circuit 16 includes an antenna 20 formed of a coil. When the activation trigger signal transmitted from the vehicle 2 is received by the antenna 20 in response to the presence of the portable device 10 in the communication area described above, A start trigger signal is output to the control circuit 17.
[0024]
The control circuit 17 is mainly composed of a microcomputer, and when an activation trigger signal is given from the transmission / reception circuit 16, the control circuit 17 outputs the ID code stored therein to the transmission / reception circuit 16. When the ID code is given from the control circuit 17, the transmission / reception circuit 16 transmits the given ID code as an air propagation signal (for example, a magnetic signal).
Thus, an activation trigger signal and an ID code are transmitted and received between the vehicle 2 and the portable device 10.
[0025]
Next, the operation of the above configuration will be described with reference to FIG. 4, particularly when the user parks and gets off with the driver's seat side door 9 opened.
First, when the user parks, opens the driver's seat side door 9 and gets off, and closes the driver's seat side door 9, in the vehicle 2, the door opening / closing detection switch 4 sends a door opening detection signal to the control circuit 6. After that, the door closing detection signal is output to the control circuit 6, and the control circuit 6 outputs an activation trigger signal to the transmission / reception circuit 3 in response thereto. Then, as described above, the transmission / reception circuit 3 to which the activation trigger signal is given transmits the activation trigger signal from the antenna 7 to the communication area indicated by A in FIG. 2 as an aerial propagation signal (see t1 in FIG. 4). . Thereafter, the control circuit 6 causes the transmission / reception circuit 3 to intermittently transmit a start trigger signal (see t3, t5, and t7 in FIG. 4).
[0026]
Now, at this time, the user is immediately after opening and closing the driver's seat side door 9, and is present in the vicinity of the driver's seat side door 9, that is, the portable device 10 is present in the communication area. Therefore, the activation trigger signal transmitted from the vehicle 2 is received by the antenna 20 in the transmission / reception circuit 16 of the portable device 10. When the activation trigger signal is received by the transmission / reception circuit 16, in the portable device 10, the activation trigger signal is output from the transmission / reception circuit 16 to the control circuit 17. The stored ID code is output to the transmission / reception circuit 16. Then, the transmission / reception circuit 16 to which the ID code is given transmits the ID code as an air propagation signal from the antenna 20 as described above.
[0027]
Next, when the ID code transmitted from the portable device 10 is received by the antenna 7 in the transmission / reception circuit 3 of the vehicle 2, the ID code is output from the transmission / reception circuit 3 to the control circuit 6 in the vehicle 2. In response to this, the control circuit 17 determines whether or not the given ID code matches the stored code stored therein, and if it matches, sends an unlock command signal to the door lock control device 5. Output (see t2 in FIG. 4). At this time, the door lock control device 5 to which the unlock command signal is given controls the doors of the doors 9 and 11 to 14 to be in the unlocked state and is in the unlocked state. Keep the doors unlocked.
[0028]
Here, consider a case where the user leaves the vicinity of the driver's seat side door 9, that is, the portable device 10 moves from the communication area to the outside of the communication area. In the vehicle 2, the control circuit 6 transmits the start trigger signal (see t 1 in FIG. 4), and then transmits the next start trigger signal by the transmission / reception circuit 3 after a predetermined time has elapsed ( 4 (see t3 in FIG. 4). At this time, if the ID code is not transmitted from the portable device 10 in response to the movement of the portable device 10 out of the communication area, the non-reception of the ID code is detected (in FIG. 4). , T4). Then, the control circuit 6 increments the counter value that it has in response to detecting that the ID code has not been received (the counter value is set to “1”).
[0029]
Next, after transmitting the start trigger signal (see t3 in FIG. 4), the control circuit 6 transmits the next start trigger signal after a predetermined time has elapsed (see t5 in FIG. 4). At this time, since the ID code is not transmitted from the portable device 10, the non-reception of the ID code is detected (see t6 in FIG. 4), and the counter value is incremented (the counter value is set to “2”).
[0030]
Next, after transmitting a start trigger signal (see t5 in FIG. 4), the control circuit 6 transmits the next start trigger signal after a predetermined time has elapsed (see t7 in FIG. 4). Even when the ID code is not transmitted from the portable device 10, it is detected that the ID code has not been received, and the counter value is incremented (the counter value is set to “3”).
[0031]
Then, the control circuit 6 outputs a lock command signal to the door lock control device 5 in response to the counter value becoming “3” (see t8 in FIG. 4). At this time, the control device 5 controls the unlocked door of the doors 9 and 11 to 14 to be locked and holds the locked door in the locked state (FIG. 4). Middle, see t9). In this case, the control circuit 6 stops transmission of the start trigger signal by the transmission / reception circuit 3 thereafter in response to the output of the lock command signal to the door lock control device 5.
[0032]
As described above, the control circuit 6 outputs a lock command signal to the door lock control device 5 after three consecutive detections of no ID code reception, and controls the door lock. In other words, the door is unlocked until the ID code is not received three times continuously.
[0033]
Here, the determination reference value that is a determination reference for switching from unlock control to lock control is “3” as described above. In this case, the user operates the operation switch 19 of the portable device 10. By doing so, it is possible to change this criterion value. Specifically, when the user performs a predetermined operation on the operation switch 19 of the portable device 10, an operation detection signal is output from the input circuit 15 to the control circuit 17, and in response to this, the control circuit 17 responds to the predetermined operation. The operation code is output to the transmission / reception circuit 16. The transmission / reception circuit 16 to which the operation code is given transmits the operation code from the antenna 20 as an air propagation signal.
[0034]
When the operation code transmitted from the portable device 10 is received by the antenna 7 in the transmission / reception circuit 3 of the vehicle 2, the operation code is output from the transmission / reception circuit 3 to the control circuit 6 in the vehicle 2. Accordingly, the control circuit 6 stores the determination reference value according to the given operation code, and thereafter operates based on the stored determination reference value.
[0035]
As described above, according to the first embodiment, when the ID code transmitted from the portable device 10 is received by the vehicle 2, on the condition that the received ID code matches the stored code stored in itself. Since each door 9, 11-14 is unlocked, and then, when non-reception of the ID code is detected three times in succession, each door 9, 11-14 is controlled to be locked. Even if the user carries the portable device 10 and moves from the inside of the communication area to the outside of the communication area, the doors 9 and 11 to 14 are not immediately lock-controlled. Even if the passenger gets off the driver's seat and takes the cargo loaded in the rear seat from the outside of the vehicle, it will be locked against the user's intention even if it moves away from the driver's seat side door 9 and moves to the rear seat side door neighborhood 12 Without being controlled, It is possible to improve the stool property.
[0036]
At this time, since the start trigger signal is configured to be transmitted as a communication area in part around the vehicle 2, specifically, the vicinity of the driver's seat side door 9, there is no need for a plurality of antennas. In addition, the power supplied to the antenna, that is, the power consumption does not increase, so that the configuration can be simplified and the cost can be suppressed, and the power consumption can be suppressed.
[0037]
In addition, since the determination reference value in the control circuit 6 can be changed in response to a predetermined operation of the operation switch 19 of the portable device 10, each door 9, 11-14 is switched from unlock control to lock control. The timing to change can be changed as appropriate according to the usage pattern, and the convenience can be further improved.
[0038]
Further, since the activation trigger signal is transmitted after the driver's seat side door 9 is opened and closed, the timing at which the activation trigger signal is transmitted follows the timing at which the user gets off the vehicle. That is, the activation trigger signal can be transmitted at an appropriate transmission timing, and this can also reduce power consumption.
[0039]
Next, a second embodiment of the present invention will be described with reference to FIG. The same parts as those in the first embodiment described above are denoted by the same reference numerals, and the description thereof is omitted. Hereinafter, different parts will be described.
In the second embodiment, in the vehicle 2, the control circuit 6 has a timer function, and the transmission / reception circuit 3 receives a start trigger signal from the antenna 7 when a start trigger signal is given. Is continuously transmitted as an airborne signal.
[0040]
Now, also in this case, a case where the user parks and gets off with the driver's seat side door 9 opened will be described.
First, when the user parks, opens the driver's seat side door 9 and gets off, and closes the driver's seat side door 9, in the vehicle 2, the door opening / closing detection switch 4 sends a door opening detection signal to the control circuit 6. After that, the door closing detection signal is output to the control circuit 6, and the control circuit 6 outputs an activation trigger signal to the transmission / reception circuit 3 in response thereto. Then, as described above, the transmission / reception circuit 3 to which the activation trigger signal is given transmits the activation trigger signal from the antenna 7 to the communication area indicated by A in FIG. 2 as an aerial propagation signal (see t1 in FIG. 5). . Note that, as described above, the control circuit 6 causes the transmission / reception circuit 3 to continuously transmit the activation trigger signal thereafter.
[0041]
At this time, if the user is immediately after opening the driver's seat side door 9 and is present in the vicinity of the driver's seat side door 9, that is, if the portable device 10 is present in the communication area, the vehicle 2 The activation trigger signal transmitted from is received by the antenna 20 in the transmission / reception circuit 16 of the portable device 10. When the activation trigger signal is received by the transmission / reception circuit 16, in the portable device 10, the activation trigger signal is output from the transmission / reception circuit 16 to the control circuit 17. The stored ID code is output to the transmission / reception circuit 16. The transmission / reception circuit 16 to which the ID code is given transmits the ID code from the antenna 20 as an air propagation signal as described above. At this time, the control circuit 17 thereafter causes the transmission / reception circuit 16 to intermittently transmit the ID code.
[0042]
When the ID code transmitted from the portable device 10 is received by the antenna 7 in the transmission / reception circuit 3 of the vehicle 2, the ID code is output from the transmission / reception circuit 3 to the control circuit 6 in the vehicle 2. 17 outputs an unlock command signal to the door lock control device 5 when the given ID code matches the stored code (see t2 in FIG. 5). At this time, the door lock control device 5 to which the unlock command signal is given controls the doors of the doors 9 and 11 to 14 to be in the unlocked state and is in the unlocked state. Keep the doors unlocked.
[0043]
Now, also consider the case where the user leaves the vicinity of the driver's seat side door 9, that is, the portable device 10 moves from the communication area to the outside of the communication area. In the vehicle 2, after receiving the ID code (see t2 in FIG. 5), the control circuit 6 determines whether or not the next ID code has been received after a predetermined time has elapsed. At this time, if the ID code is not transmitted from the portable device 10 in response to the movement of the portable device 10 out of the communication area, the non-reception of the ID code is detected (see t3 in FIG. 5). At this time, the control circuit 6 starts its own timer in response to detecting that the ID code has not been received.
[0044]
The control circuit 6 outputs a lock command signal to the door lock control device 5 in response to the time-out of the timer, for example, after 3 seconds have elapsed from the start of the timer (see t4 in FIG. 5). At this time, the door lock control device 5 to which the lock command signal is given controls the unlocked door of the doors 9 and 11 to 14 and controls the door to the locked state. Is held in a locked state (see t5 in FIG. 5). In this case as well, the control circuit 6 stops transmission of the start trigger signal by the transmission / reception circuit 3 thereafter in response to the output of the lock command signal to the door lock control device 5.
[0045]
As described above, the control circuit 6 outputs the lock command signal to the door lock control device 5 after continuously detecting the non-reception of the ID code for 3 seconds, and controls the lock of the door. In other words, the door is unlocked until the ID code is not received continuously for 3 seconds.
[0046]
Here, the timer set value that is a criterion for switching from unlock control to lock control is “3 seconds” as described above, but in this case as well, the user can use the operation switch 19 of the portable device 10. This timer setting value can be changed by operating the control circuit 6. In the vehicle 2, the control circuit 6 thereafter operates based on the changed timer setting value. It has become.
[0047]
As described above, according to the second embodiment, when the ID code transmitted from the portable device 10 is received by the vehicle 2, on condition that the received ID code matches the stored code stored in itself. Since each door 9, 11-14 is unlock controlled, and then, when non-reception of the ID code is detected continuously for 3 seconds, each door 9, 11-14 is controlled to be locked. Even if the user carries the portable device 10 and moves from the inside of the communication area to the outside of the communication area, the doors 9 and 11 to 14 are not lock-controlled immediately. The same effect as the example can be obtained.
[0048]
Also in this case, since the timer setting value in the control circuit 6 can be changed in response to a predetermined operation of the operation switch 19 of the portable device 10, each door 9, 11-14 is controlled from the unlock control. The timing for switching to the lock control can be appropriately changed according to the usage pattern.
[0049]
Next, a third embodiment of the present invention will be described with reference to FIG. The same parts as those in the first embodiment described above are denoted by the same reference numerals, and the description thereof is omitted. Hereinafter, different parts will be described.
In the first embodiment described above, the activation trigger signal and the ID code are transmitted and received as a magnetic signal. In the third embodiment, the activation trigger signal is transmitted and received as a magnetic signal, and the ID code is transmitted as a radio wave. It is configured to transmit and receive as a signal. As a specific configuration, in the vehicle 21, instead of the transmission / reception circuit 3 described in the first embodiment, a transmission circuit 22 as a transmission means for transmitting a start trigger signal as a magnetic signal, and an ID code And a receiving circuit 23 as a receiving means for receiving the signal. On the other hand, in the portable device 24, in place of the transmitting / receiving circuit 16 described in the first embodiment, the receiving circuit receives the start trigger signal. A circuit 25 and a transmission circuit 26 that transmits the ID code as a radio wave signal are provided.
[0050]
Thus, according to the third embodiment, compared with the first embodiment described above, only the configuration of the portion related to transmission / reception of the activation trigger signal and the ID code is different, and the configuration of the portion related to control is not changed at all. Therefore, the same effect as the first embodiment described above can be obtained. In this case, the configuration described in the third embodiment can be applied to the second embodiment described above.
[0051]
The present invention is not limited to the above-described embodiments, and can be modified or expanded as follows.
The configuration may be such that both the start trigger signal and the ID code are transmitted and received as radio signals.
[0052]
For example, the determination reference value and the timer set value may be changed not only by the operation by the operation switch of the portable device but also by the operation by the ignition switch or the door lock switch at the time of factory shipment.
In the second embodiment, the ID code may be continuously transmitted from the portable device.
[0053]
【The invention's effect】
  As is apparent from the above description, according to the vehicle door lock control device of the first aspect, when the ID code transmitted from the portable device is received by the vehicle side, the received ID code is stored in itself. Provided that it matches the stored memory codeA door that is locked among the plurality of doors is controlled to the unlocked state, and a door that is unlocked among the plurality of doors is held in the unlocked state,After reception of the ID code is detected at least once, when non-reception of the ID code is continuously detected a predetermined number of times,Of the plurality of doors, the unlocked door is controlled to the locked state, and among the plurality of doors, the locked door is held in the locked state.Even if the portable device moves from the communication area to the outside of the communication area, the door will not be locked immediately until the ID code is not received continuously until a predetermined number of times are detected. During this time, the door is held in the unlock control, so that the door is not lock-controlled against the user's intention, and the convenience can be improved.
[0054]
At this time, since the start trigger signal is configured to be transmitted as part of the communication area around the vehicle, a plurality of antennas are not required, and power supplied to the antennas (power consumption) As a result, the configuration can be simplified and the cost can be reduced, and the power consumption can be reduced.
[0055]
  According to the vehicle door lock control device according to claim 2, when the ID code transmitted from the portable device is received by the vehicle, the received ID code matches the stored code stored in itself. As a conditionA door that is locked among the plurality of doors is controlled to the unlocked state, and a door that is unlocked among the plurality of doors is held in the unlocked state,After the reception of the ID code is detected at least once, when the non-reception of the ID code is detected for a predetermined time continuously,Of the plurality of doors, the unlocked door is controlled to the locked state, and among the plurality of doors, the locked door is held in the locked state.Even if the portable device moves from the communication area to the outside of the communication area, the door is not locked immediately until the ID code is not received continuously until a predetermined time is detected.
