DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. First, FIG. 2 shows an overall block configuration. An ignition key 1 includes a key plate 2 which is a mechanical key and a key grip 3 which is formed to hold the key plate 2. One operation switch 4 that can be pressed is provided on the surface of 3. In addition, a transmission circuit (not shown) is provided inside the key grip 3, and when the operation switch 4 is pressed, an operation signal is generated by this transmission circuit and output as a radio wave signal. There is.

The receiving device 5 provided on the automobile side is
It is composed of the antenna 6 and the receiving circuit 7,
Upon receiving the operation signal output from the transmission circuit of the ignition key 1, the receiving device 5 demodulates the operation signal and outputs it to the control circuit 8 as a control means.

The control circuit 8 is a microcomputer, R
It is composed of an OM, a RAM, etc., and stores a control program described later. The control circuit 8 has a timer function that operates as timers T1 and T2 in the control program. The timer time t1 is set in the timer T1 and the timer time t2 (for example, 10 seconds) is set in the timer T2. It is set.

A key remind switch 9, a door courtesy switch 10 and an unlock detection switch 11 are connected to the control circuit 8. The key remind switch 9 is for detecting whether or not the ignition key 1 is inserted in the ignition key cylinder.
The door courtesy switch 10 detects the open / closed state of the door. Further, the unlock detection switch 11 is
It is to detect whether or not the door is locked.

The timer T1 starts counting operation when the key reminding switch 9 detects that the ignition key 1 is pulled out from the ignition key cylinder, and the timer T2 starts counting while timer T1 is counting. When the door courtesy switch 10 detects a state change from the open state to the closed state of the door and a subsequent state change from the closed state to the open state of the door, the timing operation is started.

The drive circuit 12 is provided with a lock signal and an unlock signal from the control circuit 8. When the lock signal is given, the door lock mechanism 13 is locked and the unlock signal is given. The door lock mechanism 13 is unlocked.

In the above-mentioned structure, the operation switch 4
The operation signal output from the transmission circuit of the ignition key 1 in response to the pressing operation of is always the same signal, but when the receiving device 5 receives the operation signal, the control circuit 8 causes the state of the door lock mechanism 13 to be changed. Is determined based on the detection signal from the unlock detection switch 11,
The door lock mechanism 13 is drive-controlled according to the state.

That is, when the receiving device 5 receives the operation signal, the control circuit 8 outputs an unlock signal to the drive circuit 12 if the door lock mechanism 13 is in the locked state, and unlocks the door lock mechanism 13. When the door lock mechanism 13 is operated and unlocked, a lock signal is output to the drive circuit 12 to lock the door lock mechanism 13.

Next, the operation of this embodiment will be described with reference to the flow chart shown in FIG. 1 and the time charts shown in FIGS. First, a description will be given of the control when the user unlocks the door lock by remote control and rides on the parked vehicle in the door lock state.

The control circuit 8 is activated when a predetermined voltage is applied from a battery (not shown) through the power supply circuit, and in step S1, a key remind switch is made to determine whether or not the ignition key 1 is inserted in the ignition key cylinder. Judgment is made based on the signal input from No. 9, and in this case, since it has not been inserted yet, it is judged as "NO" and the routine proceeds to step S2.

Then, in step S2, the control circuit 8 judges the open / closed state of the door based on the signal input from the door courtesy switch 10. In this case,
Since the door is closed, it is judged "NO" and step S
Move to 3. The control circuit 8, in step S3,
It is determined whether the receiving device 5 has received the operation signal from the ignition key 1, and if not, "N"
When it is determined to be "O", the process returns to step S1, and thereafter, in the above-described state, steps S1, S2, and S3 are repeatedly executed.

Now, when the user presses the operation switch 4 of the ignition key 1 to unlock the door so as to get on the vehicle (see (a) in FIG. 3), an operation signal is generated by the transmission circuit. And output as a radio signal. When the receiving device 5 receives the operation signal, the control circuit 8 determines whether the received operation signal is transmitted to itself, recognizes that the operation signal is transmitted to itself, and then executes the step. In S3, "YES" is determined and the process proceeds to Step S4.

In step S4, the control circuit 8 determines whether the door lock mechanism 13 is in the locked state or the unlocked state based on the signal input from the unlock detection switch 11, and in this case, Since it is in the locked state, it is determined to be "YES" and the process proceeds to step S5. The control circuit 8 then, in step S5,
An unlock signal is output to the drive circuit 12, the door lock mechanism 13 is unlocked, and the process returns to step S1. As a result, the door lock is unlocked, and the user can open the door and get on the vehicle.

Next, when the user opens the door, the door courtesy switch 10 detects the open state of the door.
The control circuit 8 determines "YES" in step S2 and returns to step S1. As a result, even if the user accidentally presses the operation switch 4 of the ignition key 1 while opening the door and trying to get on the vehicle (in FIG. 3,
(See (a)), the door lock mechanism 13 is not locked.

When the user closes the door after getting on the vehicle, the door courtesy switch 10 detects the closed state of the door, so that the control circuit 8 sets "N" in step S2.
It judges "O" and shifts to step S3 again. In step S3, the control circuit 8 determines whether or not the receiving device 5 receives the operation signal from the ignition key 1, and if not, determines “NO” and determines in step S3.
Returning to 1, the steps S1, S2 and S3 are repeatedly executed thereafter.

Next, when the user inserts the ignition key 1 into the ignition key cylinder in order to start the engine, the control circuit 8 judges "YES" in step S1 and proceeds to step S6, and in step S6. , It becomes a state of waiting for the ignition key 1 to be removed. That is, thereafter, when the user starts the engine and drives the automobile, the control circuit 8 repeatedly executes step S6.

By the way, the user can set the ignition key 1
If the operation switch 4 is erroneously pressed when inserting the key into the ignition key cylinder (see (d) in FIG. 4), the operation signal transmitted in response to the pressing operation of the operation switch 4 is transmitted. When the receiving device 5 receives,
The control circuit 8 determines “YES” in step S3 and shifts to step S4 again.

Then, in step S4, the control circuit 8 determines whether the door lock mechanism 13 is in the locked state or the unlocked state based on the signal input from the unlock detection switch 11, and in this case. As described above, immediately in step S5, since the unlocked state is set, "NO" is determined and step S7 is performed.
Move to

At this time, the user normally inserts the ignition key 1 into the ignition key cylinder while pressing the operation switch 4, so the control circuit 8 determines "YES" in step S7. Then, the process proceeds to step S6. Then, as described above, the control circuit 8 is in a state of waiting for the ignition key 1 to be removed in step S6.

Thus, even if the user accidentally presses the operation switch 4 and inserts the ignition key 1 into the ignition key cylinder, the door lock mechanism 13
Is not locked, the door lock mechanism 13 can be driven and controlled without causing any inconvenience to the user, unlike the conventional one in which the passenger needs to perform an unlocking operation while waiting outside the vehicle. it can.

Further, even after the user inserts the ignition key 1 into the ignition key cylinder and then presses the operation switch 4 again (see (e) in FIG. 4),
Ignition key 1 by key remind switch 9
Since it has been detected that is inserted into the ignition key cylinder, the control circuit 8 stops accepting the operation signal, and thus the door lock mechanism 13 is not locked.

On the other hand, when the user gets on the vehicle, closes the door, and presses the operation switch 4 again to lock the door before inserting the ignition key 1 into the ignition key cylinder ((W in FIG. 3). )), The control circuit 8 determines "NO" in step S7 and proceeds to step S8. Then, in step S8, the control circuit 8 determines whether or not the reception of the operation signal transmitted according to the pressing operation of the operation switch 4 is completed, and when the reception is completed, the process proceeds to step S9, and the step S9 is executed. S9
At, the lock signal is output to the drive circuit 12 to cause the door lock mechanism 13 to perform the lock operation, and the process returns to step S1.
This allows the user to lock the door.

Next, the user parks the car and gets off,
Control when the door is locked by remote control will be described. Here, since the ignition key 1 is inserted into the ignition key cylinder when the vehicle is operating, the control circuit 8 is in a standby state in which step S6 is repeatedly executed as described above.

When the user stops the vehicle and pulls out the ignition key 1 from the ignition key cylinder, the key remind switch 9 detects that the ignition key 1 is not inserted in the ignition key cylinder. Therefore, the control circuit 8 Determines "YES" in step S6, moves to step S10, sets timer T1 to start the time counting operation, and then executes step S1.
Move to 1.

Then, the control circuit 8 starts from step S11.
In S13, it is determined whether or not the user has performed the opening operation and the closing operation of the door during the time counting operation of the timer T1 based on the signal input from the door courtesy switch 10, and within the timer time t1. When the user opens and closes the door, step S13 is performed.
In step S14, the process proceeds to step S14, the timer T2 is set to start the time counting operation, and the process proceeds to step S15. Then, when the user presses the operation switch 4 of the ignition key 1 in order to lock the door during the time counting operation of the timer T2 (see (f) in FIG. 5), it is transmitted accordingly. When the receiving device 5 receives the operation signal, the control circuit 8 determines “YES” in step S16, and proceeds to step S17.

Then, in step S17, the control circuit 8 determines whether the door lock mechanism 13 is in the locked state or the unlocked state based on the signal input from the unlock detection switch 11, and in this case. Has
Since it is in the unlocked state, "NO" is determined and the process proceeds to step S18. In step S18, a lock signal is output to the drive circuit 12, the door lock mechanism 13 is locked, and the process returns to step S1.

Further, after that, in order to unlock the door lock, the user notices that he has left something in the car, for example.
When the operation switch 4 is pressed again (in FIG. 5,
(See (a)), the control circuit 8 executes steps S1, S2, S3, S4, and S5 as described above, and the drive circuit 1
An unlock signal is output to 2, the door lock mechanism 13 is unlocked, and the process returns to step S1.

As a result, when the user dismounts from the automobile, the user opens and closes the door within the timer time t1 after the user pulls out the ignition key 1 from the ignition key cylinder, and after the door is closed, the timer time t2.
When the operation switch 4 is operated inside, the receiving device 5 receives the operation signal and, at the same time, the door lock mechanism 13 is locked and the door can be locked.

On the other hand, when the user does not open or close the door within the timer time t1, the control circuit 8
Judges "YES" in step S11 and shifts to step S4, and if the user does not operate the operation switch 4 within the timer time t2, judges "YES" in step S15. Then, the process proceeds to step S2, and thereafter, steps S1, S2 and S3 are repeatedly executed.

From this state, the user presses the operation switch 4 of the ignition key 1 (in FIG. 5,
(See (c)), and when the receiving device 5 receives the operation signal transmitted in response thereto, the control circuit 8 performs the step S3.
Is determined to be “YES”, the process proceeds to step S4,
Further, steps S7, S8, and S9 are executed, and as described above, when the receiving device 5 finishes receiving the operation signal, it outputs a lock signal to the drive circuit 12 to lock the door lock mechanism 13. Return to step S1. This allows the user to lock the door.

According to the present embodiment as described above, when the door is closed and the ignition key 1 is not inserted in the ignition key cylinder, the user presses the operation switch 4, and accordingly the user operates the operation switch 4. When the receiving device 5 receives the operation signal, the control circuit 8 causes the door lock mechanism 13 to be locked at the time when the reception of the operation signal is completed. Therefore, until the ignition key 1 is inserted. In, the locking of the door can be prohibited. Then, when the user finishes inserting the ignition key 1 into the ignition key cylinder, the control circuit 8
As a result, the door lock mechanism 13 is no longer locked based on the fact that the ignition key 1 is inserted, so that even if the pressing operation of the operation switch 4 is completed, the locking of the door can be continuously prohibited.

Therefore, when the user gets on the vehicle and accidentally inserts the ignition key 1 while pressing the operation switch 4, the door will not be locked against the intention of the user. The drive control of the door lock mechanism 13 can be performed without any inconvenience to the person.

Further, after the user removes the ignition key 1, the door is opened and closed within the timer time t1, and after the door is closed, the operation switch 4 is operated within the timer time t2. When the receiving device 5 receives the operation signal, the control circuit 8 locks the door lock mechanism 13 at the time when the reception of the operation signal is started, so that the door lock mechanism 13 is locked when the user gets off the vehicle. The operation can be performed quickly, and the door can be locked without a feeling of strangeness.

The present invention is not limited to the above embodiment, but can be modified or expanded as follows. Two operation switches 4 may be provided so as to correspond to the lock operation and the unlock operation of the door lock mechanism 13, respectively. When the operation switch 4 is pressed during the time counting operation of the timer T1, step S4 and subsequent steps may be executed.

[0048]

As is apparent from the above description, according to the remote control device of the vehicle door lock control device of the first aspect, the door is closed and the ignition key is inserted into the ignition key cylinder. When the user operates the operation switch when there is not, and the receiving device receives the operation signal in response to the operation switch, the control means causes the door lock mechanism to be locked when the reception of the operation signal is completed. Therefore, it is possible to prohibit the locking of the door before the ignition key is inserted. Then, when the user finishes inserting the ignition key into the ignition key cylinder, the control means stops the lock operation of the door lock mechanism based on the fact that the ignition key is inserted, so the operation of the operation switch ends. Even so, it is possible to continue prohibiting the locking of the door. Therefore, even if the user accidentally inserts the ignition key while operating the operation switch when the user gets in the vehicle, the door will not be locked against the user's intention, and the door will not be inconvenient for the user. Drive control of the lock mechanism can be performed.

According to the remote control device for the vehicle door lock control device of the second aspect, the user opens and closes the door within the timer time t1 after the user pulls out the ignition key, and after closing the door. When the operation switch is operated within the timer time t2 and the receiving device receives the operation signal in response to this, the control means locks the door lock mechanism at the time when the reception of the operation signal is started. When the vehicle gets off, the lock operation of the door lock mechanism can be quickly performed, and the door can be locked without a feeling of strangeness.
