Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmitter and a receiver for controlling an automatic lock mechanism and a control method. 2. Description of the Related Art In recent years, wireless auto-lock mechanisms have come to be widely marketed for convenience. For example, an auto-lock mechanism that locks and unlocks the doors of a house wirelessly, an auto-lock mechanism that unlocks and rolls up the garage shutter wirelessly while riding in a car, and wirelessly locks the door, trunk, and glass window of a vehicle / Auto-lock mechanism for unlocking. Among them, a system for locking / unlocking a door or a trunk of a vehicle wirelessly is the most widely used as a keyless entry system (or a wireless door lock system), and the following description mainly uses this keyless entry system as an example. To do. At present, the above wireless system mainly uses light, and in the future, IrDA (Infrared Data Association)
It is expected that those using light (infrared rays) conforming to the standard will become popular.

[0002]

2. Description of the Related Art Looking at the above-mentioned keyless entry system, a transmitter for controlling an automatic lock mechanism (hereinafter, also simply referred to as a transmitter) for locking / unlocking a door of a vehicle wirelessly is integrated with an engine key. There are two main types of transmitters, namely, an integrated transmitter and a key holder type transmitter that attaches the transmitter to an engine key. Each of the integrated transmitter and the key ring type transmitter has advantages and disadvantages, but a key ring type transmitter is also widely used from the viewpoint that it is hardly damaged by static electricity particularly in winter. In Japan, the key-integrated type is more widely used, but overseas, the key holder type is widely used for the above-mentioned reasons.

[0003]

As described above, the above-mentioned key ring type transmitter is more advantageous than the above-mentioned engine key integrated type transmitter in terms of anti-static performance and the like. However, on the other hand, there are disadvantages to the keychain type transmitter.
Modern people, for example, businessmen, have more and more personal belongings to carry when going out, whether for public or private use. Various kinds of cards, notebook computers, engine keys, mobile phones, PHS, etc.

[0004] In such a social situation where personal belongings to be carried when going out increase, the above key ring type transmitter can be said to be about several cm3 in size,
There is a problem in that one more belonging is added, and the possibility of forgetting to carry is increased. Therefore, an object of the present invention is to provide a transmitter for controlling an automatic lock mechanism, a receiver thereof, and a method of operating the same, which can surely reduce the possibility of forgetting to carry, in view of the above problems. Is what you do.

[0005]

FIG. 1 is a diagram showing the principle configuration of the present invention. In the figure, reference numeral 24 denotes an auto lock unit, which corresponds to a key of a vehicle door in the case of a keyless entry system of a vehicle, and a key provided at an end of the shutter in the case of, for example, a garage shutter. It is.

The auto lock section 24 is driven by a mechanism drive section 23 which forms a part of an auto lock mechanism.
Or, it is not driven. That is, the mechanism driving unit 23 locks or unlocks the key described above. The activation or stop of the mechanism driving unit 23 is performed by a receiving unit 21 constituting an auto-lock mechanism control receiver (hereinafter, also simply referred to as a receiver) 20.
The transmission is performed by a transmitter 10 for controlling an automatic lock mechanism (hereinafter, also simply referred to as a transmitter) 10 via a wireless radiating unit 15. In FIG. 1, the wireless radiating unit 15 is illustrated as an antenna for radiating radio waves, but is not limited thereto, and may be an infrared light emitting device compliant with the aforementioned IrDA.

[0007] Transmission means 12 constituting this transmitter 10
Is built in a mobile communication terminal 11 such as a mobile phone or a PHS. The mobile communication processing unit 1 cooperating with the transmitting unit 12
3 and the key input unit 14 are functional parts that the mobile communication terminal 11 originally has. As described above, the transmitter 10 according to the present invention is characterized in that the transmission means 12 for wirelessly controlling the automatic lock mechanism 21 is formed integrally with the mobile communication terminal 11.

As described above, there are various belongings that a modern person should carry when going out.
Mobile communication terminal such as HS (hereinafter, also simply referred to as terminal) 1
1 is an important thing that you should not forget to carry. The present invention focuses on this point, and the above-described key ring type transmitter (corresponding to 10) is integrated into the terminal 11. Then, as a matter of course, a situation in which the user forgets to carry the keychain type transmitter cannot occur.

Another advantage is that batteries and antennas required for the keychain type transmitter can be shared with batteries and antennas indispensable for the mobile communication terminal 11. As a result, compared with the case where the key holder type transmitter and the terminal 11 are separately prepared, there is an advantage that the required space is reduced, and the total cost is reduced.

Further, if the above-mentioned common use is extended not only to the battery and the antenna but also to the use of the transmission function portion and the key input function portion of the terminal 11, the above-described space reduction and cost reduction can be further achieved. Become noticeable.

[0011]

FIG. 2 is a diagram showing a first embodiment of a transmitter for controlling an automatic lock mechanism according to the present invention. In this figure, the transmitting means 12, the mobile communication processing unit 13, the key input unit 14, and the wireless radiating unit 15 shown as the wireless antenna 33 are as shown in FIG.

Reference numeral 31 denotes a transmission code generator which forms part of the transmitter 10 for controlling the automatic lock mechanism.
Is a transmission unit. Reference numerals 34 and 35 are the first
A changeover switch and a second changeover switch. Terminal 11
If you want to operate for automatic lock mechanism control,
The respective contacts of the first and second changeover switches 34 and 35 are respectively switched to the illustrated side.

In the first embodiment shown in FIG.
The transmitting unit 12 is a key input unit 14 of the mobile communication terminal 11.
In response to a command from the mobile communication processing unit 13, the mobile communication processing unit 13 is switched to the mobile communication transmission unit having the mobile communication processing unit 13 as a main component and activated. This command input can be performed by pressing a predetermined one of ten keys constituting the key input unit 14.

FIG. 3 is a view showing a second embodiment of a transmitter for controlling an automatic lock mechanism according to the present invention. In this figure,
The mobile communication processing unit 13, the key input unit 14, and the transmission code generation unit 31 are as described above. In the second embodiment, the wireless radiating unit (1
As 5), light, preferably infrared light is used. FIG.
Is a light emitting source, and the light emitting device 42 is driven by an optical communication driver 41 that amplifies an output signal from the transmission code generation unit 31.

The other system in the second embodiment is the original transmission system of the mobile communication terminal.
It has a mobile communication radio section 43 for transmitting an output signal from the mobile station as a radio signal, and an antenna 44 thereof. FIG. 4 is a view showing a third embodiment of a transmitter for controlling an automatic lock mechanism according to the present invention. In the figure, a mobile communication processing unit 1
3, the key input unit 14, the transmission code generation unit 31, the antenna 33, and the mobile communication radio unit 43 are as described above.

In the third embodiment, the transmission code generator 3
1 is provided with a timer 51 for intermittently operating 1, and a code transmission unit 52 inserted between the transmission code generation unit 31 and the antenna 33. Thus, the transmission means 12 of the third embodiment intermittently generates the transmission code including the predetermined ID number for controlling the automatic lock mechanism by the timer 51 without a command from the key input unit 14 of the mobile communication terminal 11. A transmission code generation unit 31 and a code transmission unit 52 for emitting an output signal of the transmission code generation unit 31 are provided.

FIG. 5 is a diagram showing the data format of the transmission code generated by the transmission code generation unit 31 in the first embodiment and the second embodiment. In the figure, a transmission code CD is composed of illustrated bit groups B1 to B4 and is repeatedly transmitted. That is, the transmission code generation unit 31 sets the synchronization bits B1, I as the transmission code CD.
Bit B2 indicating the D number, bit B3 indicating which one is specified when there are a plurality of types of the auto lock unit 24
And a bit B4 for error checking. Each of B1 to B4 is composed of one bit or several bits.

More specifically, bit B1 is a header, which is a start bit, a bit synchronization signal, or a bit unique to a manufacturer. Bit B2 is an ID number, that is, a user authentication number. This is a code unique to the user or a code unique to each mobile communication terminal 11. Bit B3 is a switch bit. When there are a vehicle door key, a trunk key, a garage shutter (garage) key, and the like in addition to a vehicle door key, the auto lock unit 24 specifies which of these keys should be wirelessly operated. For example:

000: Number registration 001: Locked 010: Unlocked 011: Trunk open 100: Garage open Bit B4 is a check bit, and uses a parity bit or a CRC code or the like.

FIG. 6 is a diagram showing the data format of the transmission code generated by the transmission code generator 31 in the third embodiment (FIG. 4). Transmission code CD shown in FIG.
, But bit B3 is not in FIG. That is, the transmission code generation unit 31 of FIG.
, A synchronization bit B1, a bit B2 indicating an ID number, and a bit B4 for error checking are generated.

The feature of the third embodiment (FIG. 4) is that the key input unit 1
In order to unlock and lock the key without inputting a command from the control unit 4, the transmission code CD shown in FIG. 6 is always transmitted at regular time intervals. The fixed time interval is set to prevent the battery from being consumed, and the setting of the timer 51 in FIG. 4 is, for example, every 5 seconds. In this case, a sufficient margin is required for the battery capacity in order to continuously transmit radio waves intermittently. However, a mobile phone or the like has a built-in battery having a capacity sufficiently larger than the power required for such radio wave transmission, and can be charged at any time, so there is no problem.

The advantage of the third embodiment is that, in the case of a keyless entry system, the door key is unlocked only when the user approaches his vehicle, while the door key is unlocked only when the user moves away from this vehicle. Is to lock. However, there is a disadvantage that only one auto lock unit 24 can be selected. Therefore, the transmission code CD in FIG. 6 does not include the bit B3 as described above.

As will be described later, the receiver 20 for controlling the auto-lock mechanism corresponding to the third embodiment immediately activates the mechanism driving unit 23 at the same time that the user approaches and reliably receives the transmission code CD of FIG. On the other hand, when the user moves away from the vehicle (a few tens of meters away),
After a lapse of a predetermined time, for example, three minutes, after the transmission code CD cannot be correctly received, the mechanism driving unit 23
Is immediately stopped. Therefore, in this case, the code transmission unit 52 (FIG. 4) is designed to transmit a weak radio wave. Thus, the user is released from the button operation for controlling the automatic lock mechanism.

Referring to the first, second and third embodiments, the transmitter 1 for controlling the automatic lock mechanism shown in FIG.
0 is configured as follows. (I) The transmission means 12 wirelessly controls the automatic lock mechanism 21 using either radio waves or light. (Ii) The functional part of the transmitting means 12 and the functional part of the mobile communication transmitting means are configured to be partially shared with each other. For example, the transmission unit 32 shown in the first embodiment.

(Iii) The transmission means 12 has a transmission code generation section 31 for generating a transmission code including a predetermined ID number for controlling the automatic lock mechanism. This is the transmission code CD including the ID number B2 shown in FIG. 5 and FIG. (Iv) The transmission unit 12 includes a transmission unit that radiates an output signal from the transmission code generation unit 31 as a wireless signal.
This transmitter corresponds to the transmitter 32 of the first embodiment, the light emitting device 42 of the second embodiment, and the code transmitter 52 of the third embodiment.

Next, the receiver 20 for controlling the automatic lock mechanism shown in FIG. 1 will be described. FIG. 7 is a diagram showing a first embodiment of a receiver for controlling an automatic lock mechanism according to the present invention.
The automatic lock mechanism 21 includes a receiving means 22 for receiving an automatic lock mechanism control signal emitted from the automatic lock mechanism control transmitter 10 of the first or second embodiment (FIGS. 2 and 3). Auto-lock mechanism control receiver 2
0.

In this figure, an auto lock mechanism 21 and
The receiving unit 22, the mechanism driving unit 23 (for example, a solenoid or a small motor), and the auto lock unit 24 (for example, a key) are as described above. FIG. 8 is a diagram showing a second embodiment of the receiver for controlling an automatic lock mechanism according to the present invention. This is because the receiving means 22 for receiving the signal for controlling the automatic lock mechanism radiated from the transmitter 10 for controlling the automatic lock mechanism of the third embodiment (FIG. 4) is provided in the automatic lock mechanism 21. Machine 20.

In this figure, reference numerals 21, 22, 2
The components denoted by 3, 24, 61, 62, 63 and 64 are the same as those shown in the previous figure (FIG. 7), and the difference is that a timer 65 is added. The timer 65 is used to immediately stop the activation of the mechanism driving unit 23 after a predetermined time elapses, for example, three minutes after the user leaves the vehicle and cannot correctly receive the transmission code CD, as described above. Is a timer for measuring the predetermined time (3 minutes).

7 and 8, an input portion of the receiving means 22 includes an antenna 61 and a receiving portion 62 for forming a wireless link with the transmitter 10.
Is shown, the transmitter 10 of the second embodiment (FIG. 3)
When the pair is formed, the input portion is formed by a light receiving section and a light receiving amplifying section instead of the antenna 61 and the like.

In the receiver 20 (FIG. 7) of the first embodiment, the receiving means 22 includes a transmission code CD including a predetermined ID number (B2) for controlling the automatic lock mechanism included in the signal for controlling the automatic lock mechanism. And a code decoding unit 63 for decoding the same, and determines whether or not the decrypted ID number matches an ID number previously assigned to the automatic lock mechanism 21 and, when the ID number matches, determines whether the automatic lock It has a code determination unit 64 that outputs a signal for driving the mechanism 21.

Also in the receiver 20 (FIG. 8) of the second embodiment, the receiving means 22 transmits a signal including a predetermined ID number (B2) for controlling the automatic lock mechanism included in the signal for controlling the automatic lock mechanism. A code decoding unit 63 for receiving and decoding the code CD, and the decoded ID number thereof is
A code judging section 64 for judging whether or not it matches an ID number assigned to the auto lock mechanism 21 in advance and outputting a signal for driving the auto lock mechanism 21 when the ID number matches. Then, the receiving means 22 in the second embodiment does not make the above-described determination of the match (for example, 3
Further, a timer 65 is provided for outputting a signal for deactivating the automatic lock mechanism 21 when a predetermined time has elapsed.

The operation of the receiver 20 according to the second embodiment will be described. FIG. 9 shows the receiving means 2 shown in FIG.
2 (part 1) showing the operation in FIG. 1, FIG.
0 is the same figure (No. 2). Referring to FIG. 9 and FIG. 10, each step is as follows.

Step (S1): The OPEN flag indicating whether the key of the door of the vehicle in the keyless entry system is locked or unlocked is 0.
That is, it is locked. This is a state indicating that the user has left the vehicle. Step 2 (S2): Transmission code CD from transmitter 10
Check whether or not it has been received.

Step 3 (S3): When the transmission code CD is received, the ID number bit B2 shown in FIG. 6 is further checked. That is, the I registered in the receiving means 22 in advance
The match / mismatch with the D number is determined by the code determination unit 64 in FIG.
(The ID number registered in advance is stored in the ROM). If they match, the user is a regular user. Step (S4): When it is confirmed that the user is an authorized user, 0/1 of the OPEN flag is confirmed. OPEN
If the flag is 0, the door key is currently locked, and this is unlocked immediately.

Step 5 (S5): With the above unlocking,
Rewrite the OPEN flag from 0 to 1 (during unlocking). FIG.
The steps of the flowchart shown in FIG. 10 are repeatedly executed without a break. Therefore, once the OPEN flag changes from 0 to 1 as described above (when the user is in or near the vehicle), the determination in step 4 (S4) is No, and the process proceeds to step 7 (S7) described later. Jump.

Step 6 (S6): OPEN flag is set to 0
→ At the same time, the mechanism drive unit 23 in FIG.
The key of the door which is the auto lock unit 24 is unlocked. Step 7 (S7): While the code from the authorized user is being received, the above series of steps S2 → S6 is continuously and repeatedly performed. On the other hand, each time, the timer 65 of FIG. 8 is set (ON) at, for example, 3 minutes, and the countdown starts. As described above, the timer 65 expires in three minutes, for example.

However, as long as the user is in or near the vehicle, the timer 65 will continue to be set (ON) for three minutes. Step 8 (S8): However, when the user leaves the vehicle, the radio waves transmitted from the transmitter 10 are weak, so that the above steps 2 (S2) and 3 (S8)
The determination result of the code reception in 3) is No or Yes, and when the user is separated by several tens of meters or more, the determination result is almost continuous. And
If the state of No exceeds 3 minutes, the timer 65 times out. In step 8, when the timer is ON and time-out is detected, the process proceeds to step 9.

Step 9 (S9): Upon receiving the time over, the timer 65 is reset (OFF). Step 10 (S10): When the timer 65 is reset, the key of the vehicle is automatically locked. When the user returns to the vehicle again, a series of steps from step S2 is restarted.

The receiving means 22 shown in the third embodiment and the first and second embodiments described above further comprises
It may be constituted by the following two forms (I) and (II). Form (I): The receiving means 22 is a first receiving means for receiving an auto-lock mechanism control signal emitted from the auto-lock mechanism control transmitter 10, and is radiated from an existing auto-lock mechanism control transmitter. A second receiving means for receiving a signal for controlling an automatic lock mechanism.

Form (II): The format of the auto-lock mechanism control signal emitted from the auto-lock mechanism control transmitter 10 and the format of the auto-lock mechanism control signal emitted from the existing auto-lock mechanism control transmitter A second mode in which the format is unified and the above-described first receiving means and second receiving means are configured to be one common.

The details are as follows. The first
In the form (I), the signal transmitted from the mobile communication terminal 11 and the signal of the conventional keyless transmitter are separate, and a receiver having two reception systems is used. Although the scale of the receiver is large, the unification of the transmission format on the mobile communication terminal side enables the operation of the receiver having this function from all the mobile communication terminals 11 including the keyless transmitter. It becomes possible.

In the second embodiment (II), by unifying the signal transmitted from the mobile communication terminal 11 and the signal of the conventional keyless transmitter, both codes are received by the same receiver as the conventional one. It can be so. In the case of the radio wave method, the frequency, modulation method, signal format, etc. are unified. In the case of the optical communication system, the modulation system and the signal format are unified.

When the mobile communication terminal 11 such as a mobile phone or a PHS, which incorporates the above-described transmitter for controlling the automatic lock mechanism, is widely used, for example, in a keyless entry system, security such as theft prevention of a vehicle is provided. Must be taken into account. That is, the method of setting the ID number (bit B2) shown in FIGS. 5 and 6 is a problem in operation of the automatic lock mechanism. Hereinafter, several examples of the setting of the ID number will be described.

FIG. 11 is a diagram schematically showing a first example of ID number setting. The ID number (B2) set in the auto-lock mechanism control transmitter is assigned to the auto-lock mechanism 2
It is determined based on a telephone number unique to one user. This is a mobile phone or PHS phone number held by the user.
Since this telephone number is originally transmitted inevitably in the communication protocol between a mobile phone or the like and a base station,
Very little software or hardware modification is required. Also, due to its nature, the same telephone number can be found anywhere in Japan.
It is impossible. A part of the telephone number may be added or deleted.

FIG. 12 is a diagram schematically showing a second example of ID number setting. The ID number (B2) set in the transmitter for controlling the auto-lock mechanism is transmitted to the mobile communication terminal 11
Is determined based on a serial number and / or a technical standard conformity certification number, a so-called technical number. In general, a mobile communication terminal is given a unique serial number at the time of manufacture, and is given a technical number indicating that the mobile communication terminal has passed the certification because it is a wireless device. This second example focuses on this, and these numbers are usually assigned to the R in the terminal.
OM is already written in the manufacturing process. Therefore, little modification is required on software or hardware. Note that a part of the number may be added or deleted.

FIG. 13 is a diagram schematically showing a third example of the ID number setting. The ID number (B2) set in the auto-lock mechanism control transmitter is assigned to the auto-lock mechanism 2
It is determined by a number arbitrarily designated by one user. In other words, the user has decided freely. For example, if the date of birth and the time are 0 November 23, 1960
If it is 5:38, it is “196011230538”. Such an ID number is a number that a malicious third party will not know even if they do their best.

One of the features of the present invention is that such a completely arbitrary ID number can be adopted. This is because the mobile communication terminal 11 is provided integrally with the transmitter 10. Since the terminal 11 always has a key input unit (numeric keypad) 14, a completely free ID number can be input using this numeric keypad. be able to. FIG. 14 shows the fourth ID number setting.
It is a figure showing an example graphically.

An ID number obtained by further encrypting the ID number determined from any of FIGS. 11 to 13 is used. Although sufficient security is ensured even with the ID numbers shown in FIGS. 11 to 13 described above, it is almost impossible to guess the ID numbers if encryption processing is added, and the confidentiality is dramatically improved.

As one of the encryption processes, there is a process using a mathematical method, which can be sufficiently performed using a microcomputer of about 8 bits. Alternatively, there is a scramble process.
This can be realized simply by using only a logic circuit (without using a microcomputer). FIG. 15 is a diagram schematically illustrating a fifth example of ID number setting.

The ID number (B 2) set in the automatic lock mechanism control transmitter is determined based on a random number generated inside the mobile communication terminal 11. For example, a random number is generated using time data. Such an ID number is also a completely unguessable number for a malicious third party, and the confidentiality is improved. Although illustration is omitted for the sixth example, a so-called rolling code method is used together. That is, the ID number (B2) determined by any of FIGS. 11 to 15 is changed every time one ID number is transmitted according to the rolling code method.

In the format of the transmission code CD,
If the ID number (B2) is fixed, while a legitimate user is transmitting the code CD, a malicious third party eavesdrops on the code with another receiver, and the vehicle is stolen with the eavesdropped code. The rolling code system is commonly used in Europe. In the case of the rolling code system, information indicating the current transmission number is added to the transmission code CD. A sufficiently long code length representing the transmission number information is used. On the receiver side, the transmission number received last time is stored in the memory (the transmission number received this time is newer than the previous number), and the locking / unlocking process is executed only when the number is equal to or less than the previous number + α. It has a mechanism. Note that these codes may be encrypted or confidentiality may be enhanced. In addition to the above description of + α, the user may accidentally unintentionally hit the transmission code transmission button after leaving the vehicle. The number of such blank shots is added as a margin (for example, α + 10).
That is + α.

When an ID number is set on the transmitter 10 side by any of the first to sixth examples, a copy of the ID number needs to be transferred to a memory in the corresponding receiver 20. That is, the ID number (B2) determined by any one of the first to sixth examples is registered in the corresponding auto lock mechanism control receiver 20 by pairing. For this registration, the method employed in the current keyless entry system may be used as it is. Generally, when a user purchases a keyless entry system, a vehicle operator (sales dealer) performs registration (pairing) on the receiver side using special means.

If the pairing is to be performed by the user individually, the transmission code is written from the transmitter 10 while the registration button provided on the auto-lock mechanism control receiver 20 is depressed when the vehicle is turned on. May be executed. Registration of an ID number on the transmitter side can also be performed as follows. Auto-lock mechanism control transmitter 1
The ID number set in 0 is set by transmitting a telephone call to the mobile communication terminal 11 from the telephone of the operator (sales dealer) of the vehicle to be registered.

Although the registration of the ID number in the receiver 20 is originally performed by the sales dealer as described above, the registration is performed by the user. This is based on the fact that the transmitter 10 is integrated with the mobile communication terminal 11, and the ID number is sent from the telephone of the sales dealer to the terminal 11, and at this time, the terminal 11
This ID number is written in the memory of the transmitter 10 in the inside.

After that, the user can perform the pairing of the ID number to the receiver 20 by himself. Finally, a usage mode unique to the present invention will be described. As an example, assume one situation. A company employee A of a company goes to work at this company and tries to go to work outside with his vehicle parked in the parking area of this company. However, at this time, the employee A notices that he or she has left the mobile communication terminal 11 having the built-in automatic lock mechanism control transmitter 10 at home. Therefore, the vehicle in charge of company employee A cannot depart to the promised destination.

Even if such a situation occurs, it is not enough for the office worker A to return the terminal 11 to his / her home. Company employee A once rents a spare terminal 11 (or terminal 11 of company employee B) to the company. The office worker A calls the sales dealer from the borrowed terminal 11, and inputs the ID number of the vehicle of the employee A (known to the sales dealer from which the keyless entry system is purchased) to the terminal 1 which is currently calling.
Request 1 (for company employee B) to send a telephone call.

Here, in the transmitter 10 in the spare terminal 11 (or in the terminal 11 of the office worker B), the ID number of the vehicle of the office worker A is temporarily registered. With this ID number, the company employee A unlocks the key of the door of the vehicle in charge and can depart. That is, the automatic lock mechanism control receiver 20
By transmitting the ID number to another mobile communication terminal different from the mobile communication terminal 11 from the telephone of the vehicle operator who registered the ID number with respect to the other mobile communication terminal, It is possible to register the ID number in the terminal and drive the auto lock mechanism 21 from the other mobile communication terminal.

[0058]

As described above, according to the present invention, a key ring type transmitter for controlling an automatic lock mechanism, which has been conventionally independently provided as one of the items to be carried, is provided, for example, in a portable telephone. The possibility of forgetting to carry this keychain-type transmitter is extremely low, since it has been integrated into it. This is because mobile phones have become one of the personal belongings of modern people, especially businessmen.

Even if the user forgets to carry the portable telephone, at least the key can be unlocked using the portable telephone function as described above (note that the manual locking is possible when leaving the vehicle). Further, the user can freely set an ID number by using a key input function inherent in the mobile phone, and can further register the ID number. In this case, security is a concern, but if one is selected from among the various ID number settings described above, an ID number that cannot be guessed at all by a malicious third party can be obtained.
