Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention is applied to, for example, doors of vehicles and houses (hereinafter referred to as opening/closing bodies), and is used as a wireless door lock etc. in place of a mechanical key. Unlocking the lock
The present invention relates to a lock control device that performs locking.

<<Background of the Invention>> The applicant of the present application previously proposed a "radio wave type key system" in Japanese Patent Application No. 132118/1982 (Japanese Patent Application No. 24075/1988). This radio key system is applied, for example, to vehicle door locks, where the driver carries a transmitter instead of a key, and the door locks only when the person in possession of the transmitter operates a switch installed on the door. The structure is such that the door can be unlocked or locked.

FIG. 1 is a block diagram showing a schematic configuration of the radio key system (hereinafter referred to as a locking control device). In the figure, a transmitter 1 is housed in a card-type case, and this card-type transmitter 1 is carried by a driver in place of a mechanical key of a vehicle 18.

On the other hand, a control device 2 is mounted on the vehicle 18 side, and a loop antenna 10 is mounted on the window.
A switch 12 is provided near the door handle on the driver's side door.

The card type transmitter 1 is always powered on and is in a state where it can receive a request signal transmitted from the control device 2 on the vehicle body side.
When the driver carrying this card type transmitter 1 manually operates the switch 12 to unlock the door, the request signal generating circuit 11 in the control device 2 shown in FIG. 1 is activated. A request signal is transmitted from the loop antenna 10 for a certain period of time. The request signal transmitted from the loop antenna 10 is received by the loop antenna 3 of the card type transmitter 1 by electromagnetic induction. Then, on the card type transmitter 1 side, the request signal generation circuit 7 detects that the request signal is transmitted from the control device 2 on the vehicle 18 side, and activates the code signal generation circuit 8.

When the code signal generation circuit 8 is activated, a code signal unique to the vehicle 18 previously stored in the code storage circuit 9 (a different code is set for each vehicle)
Output. Then, in the modulation circuit 5, the carrier signal supplied from the carrier oscillation circuit 6 is modulated by the code signal, and transmitted via the output circuit 4 and the loop antenna 3.

Then, on the vehicle side, the unique code signal transmitted from the card type transmitter 1 is received by the loop antenna 10, and the received unique code signal is subjected to code verification via the receiving/demodulating circuit 13. The signal is supplied to the circuit 14.

The code matching circuit 14 determines whether or not the vehicle-specific code signal registered in advance in the code storage circuit 15 matches the received code signal. The actuator drive circuit 16 is driven only in certain cases.

When the actuator drive circuit 16 is driven, the actuator 17, which unlocks and locks the door lock, is driven to unlock the door lock.

In this way, the door lock is unlocked and locked only when the code signal on the card type transmitter 1 side matches the code signal registered in the control circuit 2 on the vehicle side. Even if a person who does not have the card type transmitter 1 attempts to unlock the door lock, the door lock will not be unlocked. Also,
Even if a person carrying a card type transmitter 1 with a different code signal attempts to unlock the door lock, the door lock will not be unlocked in the same way. As a result, the card-type transmitter 1 has the same security performance as a conventional mechanical key.

Furthermore, since the card-type transmitter 1 can be used while being stored in a pocket or bag, it eliminates the need to take out the key every time the key is unlocked or locked, unlike conventional mechanical keys. becomes.

The actuator 17 is configured to reverse the door lock state each time it is driven.
If the door lock is locked before driving, it is unlocked, and if it is unlocked before driving, it is locked.

By the way, as described above, this device is configured to be locked and unlocked by the person carrying the card type transmitter 1 turning on the activation switch. Therefore, for example, a situation may occur where the person carrying the vehicle unintentionally operates the switch twice or forgets to operate it, and leaves the vehicle thinking it is locked, but it is actually left unlocked. Conceivable.

This invention has been improved in consideration of the above points.

<<Object of the Invention>> The object of the present invention is to enable reliable locking even if the activation switch malfunctions or is forgotten, and to further improve theft prevention performance.

<<Explanation of Embodiments>> Fig. 4 shows the first embodiment of the locking control device according to the present invention.
FIG. 5 is a block diagram showing the configuration of the card-type transmitter in the embodiment, and FIG. 5 is a circuit diagram showing the configuration of a control device provided on the opening/closing body side, for example, in a vehicle.

A card-type transmitter (hereinafter referred to as a transmitter) 30 shown in FIG. 4 is housed in a thin card-type case approximately the size of a business card, similar to the device of the prior application shown in FIG. It is carried by the driver in the same way as a conventional mechanical key.

The transmitter 30 includes a loop antenna 31, a receiving/demodulating circuit 32 that detects a request signal (signal to start locking/unlocking operation transmitted wirelessly from the vehicle body side), a microcomputer 33, and stores a unique code. It is generally composed of a memory 34 for transmitting a unique code signal, a carrier oscillation circuit 36 and a modulation circuit 35 for transmitting a unique code signal.

On the other hand, a control device 40 as shown in FIG. 5 is mounted on the vehicle body side. This control device 40 is
Microcomputer (hereinafter referred to as CPU)
It is mainly composed of CPU53, and this CPU5
3 is a microprocessor unit, I/O interface circuit, memory (ROM, RAM, etc.)
It is equipped with a timer, etc.

The loop antennas 41a and 41b are respectively arranged near the trunk lock of the vehicle body at a predetermined interval.

The other pair of loop antennas 41c and 41d are
One loop antenna 41c is placed in the vicinity of the driver's side door mirror, and the other loop antenna 41d is placed inside the driver's seat.

Corresponding to the loop antennas 41a to 41d, push button switches (hereinafter referred to as activation switches) are installed at predetermined positions on the outside of the driver's side door and trunk.
62 and 63 are attached.

A 90° phase shifter 42, 43 is connected to one antenna 41b, 41d of the two pairs of loop antennas, so that the transmitted signal and the received signal are shifted by 90°.

The switching circuits 46a, 46b activate either the trunk side antenna pair 41a, 41b or the driver seat side antenna pair 41c, 41d in response to the switching signal _S1 output from the CPU 53. This is an analog switch circuit.

The door switch 57 is a switch that detects whether the driver's side door is open or closed.
ON, turns OFF when the door is closed.

Similarly, the door switch 58 is a switch that detects the open/closed state of the passenger door and the two rear doors (in the case of a sedan).
ON, turns OFF when the door is closed.

The lock knob switch 60 is a switch that is turned ON when the door lock knob provided on the inner surface of the driver's seat side door is pushed in to lock the door.

The lock state detection switch 61 is a switch that detects the state of the door lock mechanism of the driver's side door, and when the door lock mechanism is in the locked state,
OFF, and ON when the lock is unlocked.

The power supply start detection circuit 54 includes a switch 57,
Any one of 60, 61, 62, 63
ON (However, if switches 57 and 61
is driven for a predetermined period of time (when switching between ON and OFF), and power is supplied from the power supply 55 to each circuit. Furthermore, when the power supply holding signal _S3 supplied from the CPU 53 arrives, the power supply is maintained regardless of the switch operation of each of the switches, and the power supply is stopped when the CPU 53 enters the standby state. It's summery.

When the trunk unlock signal _S8 is output from the CPU 53, the relay 65 turns on the transistor _Tr1 .
This activates the trunk lock unlocking solenoid (not shown) to unlock the trunk lock.

Relay 66 and relay 67 each connect to CPU 5.
Transistors Tr 2 and _Tr 3 are activated by door lock signal S ₇ and door unlock signal S ₆ output from transistor Tr ₃ .
The relay 66 rotates the motor that automatically opens and closes the door lock in the reverse direction to lock the door lock, and the relay 67 rotates the motor in the normal direction to unlock the door lock.

Further, a unique code is input from the CPU 53 via a multiplexer 69.

Next, FIG. 6 is a flowchart showing the contents of the process executed by the microcomputer 33 in the transmitter 30, and FIGS. 3 is a flowchart showing the contents of the processing to be performed.

First, an example will be explained in which the driver locks the door when getting out of the car.

When the driver exits the vehicle, the driver stops the vehicle, removes the key from the ignition key cylinder, opens the driver's side door, exits the vehicle, and then closes and locks the door. Do this.

At this time, if the driver is carrying the transmitter 30, he or she can turn on the start switch 62 after closing the door, close the door with the lock knob pushed in, or lock the door with the key after closing. Three ways of locking are possible.

First, when the driver opens the driver's door to exit the vehicle after removing the key from the ignition key cylinder, the door switch 57 is turned on and the CPU 53 is activated. As a result, the processes shown in the flowcharts of FIGS. 6 to 8 are executed.

In FIG. 7, when the start switch 62 is turned on, the determination result in step 10 becomes YES and the process proceeds to step 11, where request signal output processing is executed. This process is a process in which the CPU 53 outputs the drive signal S ₅ and the switching signals S ₄ and S ₁ , respectively. As a result, the carrier wave generated from the oscillator 50 is modulated in a predetermined manner by the modulator 49 to become a request signal, and this request signal is transmitted to the switching circuit 48 (consisting of switches 48a and 48b), the switching circuit 46a, and the high frequency The request signal is transmitted by supplying it to the loop antennas 41c and 41d via the amplifier 45b.

At this time, the 90° phase shifter 43 transmits the request signal generated from the loop antenna 41d as a signal whose phase is shifted by 90° with respect to the request signal generated from the loop antenna 41c. This is a configuration to ensure that the transmitted request signal is received by the transmitter 30 carried by the driver.

When the request signal is transmitted, the transmitter 3
On the 0 side, the determination result in step (1) of the flowchart shown in FIG. 6 is YES. By this,
The process of the next step (2) is executed to read the vehicle-specific code signal stored in the memory 34 in advance, and the pulse train signal corresponding to the read code data is executed in the next step (3). A process is performed to output the signal to the modulation circuit 35.

During this time, in the vehicle body side control device 40,
After the process of step (11) in FIG. 7 is completed, the standby state continues until the above-mentioned unique code signal is received in step (12).

Then, the unique code signal is transmitted to the antenna pair 41.
When received by the loop antenna 41d, the signal received by the loop antenna 41d is
After a 90° phase shift is performed via the 90° phase shifter 43 and combined with the signal received by the loop antenna 41d, the switching circuit 46b, the switching circuit 4
8. Detector/demodulator 52 via high frequency amplifier 51
supplied to This detector/demodulator 52 extracts the code signal component in the carrier wave, and the CPU 53 extracts the code signal component from the carrier wave.
is input to.

At this time, the input code signal is continued and temporarily stored in a predetermined register by the process of step (13) in FIG.

Next, proceeding to step (14), the unique code data set on the vehicle body side (hereinafter referred to as the vehicle body side unique code) is read from the multiplexer 69, and the received unique code data (hereinafter referred to as the received unique code data) is read from the multiplexer 69. A unique code) is compared to determine whether the two match.

If the result of the above-mentioned matching determination process is "mismatch", the transmitter 30 carried by the person who operated the activation switch 62 does not correspond to this vehicle;
That is, it is determined that the person operating the switch is not the owner of the vehicle, and the following door locking operation is not performed.

On the other hand, if the received unique code and the vehicle body unique code "match", proceed to step (17),
Door lock signal _S7 is output from CPU53, transistor _Tr2 is turned on, and relay switch 6 is turned on.
6 is activated, which causes the door lock motor to reversely rotate and lock the door lock.

In this way, the door lock is locked only when the person in possession of the transmitter 30, which has a code that matches the unique code of the vehicle body, turns on the activation switch 62.

Next, the person carrying the transmitter 30 turns on the activation switch 62.
I will explain what happens when you try to lock your car by operating it, but you accidentally do it twice and leave your car.

First, by turning on the start switch 62 for the first time, the processes shown in FIGS. 6 and 7 are executed and the door lock is locked.

Next, when the start switch 62 is turned on for the second time, the process shown in the flowcharts of FIGS. 6 and 7 is executed again, and the door lock becomes unlocked. Then, the determination result in step (20) of the flowchart of FIG. 8 becomes NO, the process proceeds to step (21), and a timer in the CPU 53 is started. Then, when the timer predetermined time has elapsed (N ₁ =0), the process advances to step (26).

In the flowchart shown in FIG. 8, the door open flag is set to "1" when the door is opened, and when this flag is set, the lock is not locked or unlocked. Not possible. Therefore, since the door has not been opened at this point, the door-to-door flag is in the reset state of "0", and the determination result in step (26) is NO, and the process returns to step (17).
The actuator drive command is output and the lock is locked.

Also, if the door is opened within a predetermined time, the door open flag is set to "1", so if the door is locked or
After setting the door open flag to "0" without performing an unlocking operation, the process ends (step (27)).

In this way, even if the owner of the transmitter 30 accidentally operates the activation switch 62 twice when locking the door lock and leaves the vehicle with the door unlocked, the transmitter 30 will automatically operate after a predetermined period of time. Because it is locked,
It is possible to further improve the theft prevention performance.

Next, a case will be described in which the person carrying the transmitter 30 unlocks the door lock again.

When the start switch 62 is turned on, the vehicle-side control device 40 executes step (11) as described above.
The processes of steps (1) to (17) are executed, while the processes of steps (1) to (3) are executed on the transmitter 30 side, and the door lock is unlocked.

Next, the process proceeds from step (20) to step (21), where the timer starts, and if the door is opened before the predetermined time elapses, the process proceeds from step (24) to step (25), and the door open flag is set. be done. Thereafter, when the timer time has elapsed, the process proceeds to step (26) and step (27), the door open flag is reset, and the series of processing ends with the door lock still in the locked state.

Therefore, once the door is opened after unlocking by operating the start switch 62, the door will not be locked automatically, so the driver may leave the transmitter 30 inside the vehicle and leave it outside the vehicle for a while. Even if the transmitter 3
0 will not be trapped inside the vehicle.

On the other hand, if the door is not opened even after a predetermined period of time has passed after the door lock is unlocked, as described above,
The door lock will be locked again.

Next, FIG. 9 is a flowchart showing the contents of the processing executed in the vehicle body side control device according to the second embodiment of the present invention. Note that the electrical configuration of the transmitter 30 and the vehicle-side control device 40, and the transmitter 3
Since the contents of the processing executed in Embodiment 0 are the same as those in the first embodiment, the explanation thereof will be omitted.

This embodiment device can be used when the person carrying the transmitter 30 forgets to operate the activation switch 62 when locking the door lock, and leaves the vehicle without operating the switch 62, that is, in the unlocked state. It locks automatically.

In FIG. 9, the door opening/closing flag is a flag that is set when the door is opened or closed, and is reset after a predetermined time has elapsed.

The check flag is a flag that is set after the start switch is not turned on and a predetermined time has elapsed, and is reset when the start switch is turned on.

The drive reservation flag is a flag that is set when the received unique code and the vehicle body-side unique code match before the timer predetermined time elapses, and is reset when they do not match. Therefore, the actuator is not driven when the drive hold flag is set.

First, the person carrying the transmitter 30 turns on the activation switch.
If the ON operation is not performed, the determination result in step (30) becomes NO and the process proceeds to step (31), where it is determined whether the door opening/closing flag is set. If the door has not been opened or closed at this point, the door open/close flag is in a reset state, and the process proceeds to step (32). If the door is opened or closed after that, the door open/close flag is set and the timer is reset. starts (step (33)).

Next, a request signal is transmitted (step (38)), and when a code signal is transmitted from the transmitter 30, a match determination process between the received unique code and the vehicle body-specific code is executed in step (39). be done.

If the code is determined to be a "match" in step (40), since the person carrying the transmitter 30 is located near the vehicle, the process proceeds to step (41). At this time, timer time N ₂ is N ₂₀ (initial state)
In this case, the process advances to step (44) and the drive reservation flag is set to "1". Therefore, the actuator will not be driven. Further, if the timer predetermined time has elapsed, the process proceeds from step (41) to step (42), where it is determined whether or not the check flag is in the set state. However, since the start switch 62 has not been turned on, This check flag is in the set state, and the process returns to step (30) again.

In this manner, if the activation switch is not turned on and the person carrying the transmitter 30 is located near the vehicle, the door lock will not be locked even if the door lock is in the unlocked state.

Next, if the determination in step (30) is NO again, the process proceeds to step (31), where a determination process is executed to determine whether or not the door open/close flag is set. Therefore, proceed to step (35).

In step (35), a process is executed to determine whether or not the predetermined time has elapsed. If it is determined that the predetermined time has not elapsed, the process proceeds to step (37), where the timer counts down (N ₂ =N ₂ -1). below,
The processes of steps (30)→(31)→(35)→(37) are repeatedly executed until a predetermined time has elapsed (N ₂ =0).

When the timer predetermined time has elapsed, the next step (3
Proceeding to step 6), the door opening/closing flag is reset and the check flag is also set.

Then proceed to step (38) and step (39),
A request code is transmitted, and a match determination process between the received unique code and the vehicle body-specific code is executed. At this time, if the person carrying the transmitter 30 is not near the vehicle, the two codes do not match, so the determination result in step (40) becomes NO, and the process then proceeds to step (45).

In step (45), a process is executed to determine whether or not the drive hold flag is set. At this time, since the drive hold flag is in the set state, the process proceeds to step (46), where a process is performed to reset the drive hold flag. will be done.

The process then proceeds to step (43), where an actuator drive command is output and the door lock is locked.

Next, a case will be described in which an attempt is made to unlock the door again after it has been locked through the above-described process.

First, the person carrying the transmitter 30 turns on the activation switch 62.
When turned ON, the check flag is reset (steps (30) and (34)). After steps (38) to (40) are executed, step (41) is executed.
Proceed to. At this time, the timer count value _N2 is “0”
Therefore, the process proceeds to step (42), where the check flag is set and the reset state is determined. However, since the check flag is in the reset state,
The process advances to step (43), where an actuator drive command is output, the actuator is activated, and the door lock is unlocked.

Then, after unlocking the door lock and opening/closing the door, if the person carrying the transmitter 30 is located inside the vehicle or near the vehicle, steps (30) to (33)→
Proceed as (38) to (42). At this time, since the check flag is in the set state, the determination result in step (42) becomes YES, and the process returns to return. Therefore, the door lock is not automatically locked.

FIG. 10 and FIG. 11 are flowcharts showing the processing contents of the third embodiment of the present invention.
Note that this flowchart is a combination of the flowcharts of the first and second embodiments, and the electrical configuration is also the same, so a description thereof will be omitted.

In each of the above embodiments, locking/unlocking of a door lock was explained as an example, but the present invention is not limited to this, and is also applicable to a glove box lock, a trunk lock, a steering lock, etc. Of course.

Further, when the door lock is automatically locked, all of the above locks may be automatically locked.

<<Effects of the Invention>> As explained in detail above, in the locking control device according to the present invention, even if the activation switch is operated incorrectly or forgotten, the lock is automatically locked, so the theft prevention property is improved. It becomes possible to further improve the
