U), and electric power is supplied to the base unit 2A from the battery of the vehicle 3.

FIG. 3 is a diagram showing the relationship between the reception level of the master unit 2A and the position of the slave unit 1A. When the slave unit 1A is in a certain area (unlocking area 19) around the vehicle 3. , The base unit 2A can receive the ID code with a reception intensity of a certain level or higher, and when the handset unit 1A goes out of the unlocking area 19, the reception intensity of the base unit 2A is a certain level or lower. The reception level is set in the determination unit 16 so as to be determined to be present. Therefore, when the carrier of the child device 1A is in the unlocking region 19 of FIG. 3, the door 4 of the vehicle 3 is automatically unlocked by the parent device 2A, and when the user goes out of the unlocking region 19, the parent device 2
Automatically locked by A. The unlocking area 19
May be set in the vicinity of the door 4 of the driver's seat as shown by an imaginary line in FIG.

As shown in FIG. 2, the master unit 2A includes a resettable prohibition switch 20 installed inside the vehicle 3,

And a prohibition processing unit 22 for prohibiting automatic locking / unlocking. The prohibition switch 20 and the door opening / closing sensor 21 may be of any form, but the prohibition switch 20 is of a resettable push button switch type provided at a position where it is easy to operate by hand from inside the vehicle 3. Is preferred.
Further, as the door opening / closing sensor 21, for example, an existing switch provided between the vehicle body and the door 4 for turning on / off the room lamp can be used. Then, when the door 4 is closed and the prohibition switch 20 is pressed, the prohibition processing unit 22 prohibits automatic locking / unlocking and the locking / unlocking by the lock knob 23 is prioritized (prohibition mode). Further, when the door 4 is opened, the prohibition processing unit 22 detects that the door 4 has been opened via the door opening / closing sensor 21, releases the prohibition mode, and thereafter is automatically locked / unlocked according to the determination result of the determination unit 16. Return to the automatic locking / unlocking mode.

In the prohibition mode in which the prohibition switch 20 is turned on to prohibit the automatic locking / unlocking, when the lock knob 23 provided on the door 4 is locked, the door lock switch 24 is turned on and the locking / unlocking is performed. Control unit 17
Outputs a lock signal to the door lock control unit 18 to lock the lock mechanism of the door 4. When the lock knob 23 is unlocked, the door lock switch 24 is turned off, and the locking / unlocking control unit 17 outputs an unlocking signal to the door lock control unit 18 to unlock the locking mechanism of the door 4.

When the locking / unlocking control section 17 outputs a locking signal or an unlocking signal to the door lock control unit 18 to lock or unlock the locking mechanism, an operation confirmation signal notifying the locking or unlocking is modulated by the transmission circuit 25. Antenna 13
Is transmitted to the child device 1A.

Next, the operation of the keyless entry system will be described. FIG. 4 is an operation flowchart of the child device 1A, and FIG. 5 is an operation flowchart of the parent device 2A. First, the operation of the child device 1A will be described with reference to FIG. When the slave unit 1A transmits the ID code held in the memory 6 from the transmission circuit 7 and the antenna 8 to the master unit 2A (S31), the slave unit 1A stops transmitting the ID code for the predetermined time set in the timer 9 (S31).
32, S35), when the transmission stop time elapses for a predetermined time,
The ID code is transmitted again (S31). In this way, the handset unit 1A transmits the ID code at every predetermined time. When the handset unit 2A continuously transmits the ID code, it is unlocked when the received signal strength at the base unit 2A is near the boundary level. This is because the lock may be repeatedly malfunctioned, so that the malfunction is prevented by providing a temporal hysteresis.

Further, when the slave unit 1A is in the transmission stop state,
It is monitored whether the operation confirmation signal is received (S3
3) When receiving the operation confirmation signal, the confirmation device 12 such as a locking or unlocking buzzer or a lamp is operated according to the content of the operation confirmation signal (S34).

In this embodiment, the confirmation device 12 is provided on the slave unit 1A, but it may be provided on the vehicle 3 side. For example, when locked or unlocked, the room lamp may blink several times.

Next, the operation of the master unit 2A from the time when the carrier of the slave unit 1A gets on the vehicle to the time of getting off the carrier again will be described with reference to the flowchart of FIG. The base unit 2A branches the mode depending on whether the prohibit switch 20 is turned on (S4
1) Normally, after waiting for reception (S46), the automatic lock / unlock mode is set (MD1). When the prohibit switch 20 is turned on, the mode is switched to the prohibit mode (MD2), and the door 4 is opened (S4).
5) The prohibit mode is released and the automatic locking / unlocking mode is restored again (MD1). Here, the automatic locking / unlocking mode is a mode in which the locking / unlocking means is automatically locked / unlocked based on the result of determination as to whether or not the received identification information is correct.

Normally, the master unit 2A is in the automatic locking / unlocking mode (MD1) as shown in FIG. Therefore, for example, when the person carrying the child device 1A enters the unlocking area 19 of FIG. 3 and the parent device 2A receives the ID code (S46), the ID
The codes are collated (S47), and if the ID codes do not match, they are locked (S48). If the ID codes match, it is further determined whether the received signal level is above a certain level (S
49) If it is above a certain level, it is unlocked (S50), and if it is less than the certain level, it is locked (S52). Therefore, only the correct carrier of the child device 1A can open the door 4 and enter the vehicle 3. When unlocked, an unlocking operation confirmation signal is transmitted to the child device 1A (S51), and the confirmation device 12 of the child device 1A is operated. Similarly, when locked, a lock operation confirmation signal is transmitted to the child device 1A (S53), and the confirmation device 12 of the child device 1A is operated.

Even if the person carrying the child device 1A gets into the vehicle 3 and operates the lock knob 23 to lock the vehicle, if the automatic locking / unlocking mode is set, the locking / unlocking control unit 17 immediately starts. An unlocking signal is output from and it cannot be locked. In that case, when the prohibition switch 20 is turned on, the prohibition switch 20 is a return type and thus returns to off, but the master device 2A is switched to the prohibition mode (S41, MD).
2). When the mode is switched to the prohibit mode, the door lock switch 24 has priority, and the lock / unlock control unit 17 does not operate depending on the determination result of the determination unit 16. Therefore, the door 4 can be arbitrarily locked or unlocked from the inside of the vehicle 3 by operating the lock knob 23 (S42) (S43, S4).
4). In particular, the door 4 can be locked so that the door 4 cannot be opened carelessly or the door 4 cannot be opened from the outside.

After this, when the carrier of the child device 1A opens the door 4 to get out of the vehicle 3 (S45), the prohibit mode is released and the automatic locking / unlocking mode is restored (MD1). That is, while the door 4 is unlocked while in the unlocking area 19, the door 4 is locked when it goes out of the unlocking area 19.

When the door 4 is opened in this way, the prohibit mode is released and the automatic locking / unlocking mode is restored. Therefore, even if the slave 1A is left in the vehicle 3, the door 4 can be locked and the door 4 can be closed. Therefore, there is no fear of being locked out of the vehicle 3.

Further, even if the carrier of the child device 1A goes out of the unlocking area 19 and is automatically locked, the locks and unlocks of those left in the vehicle 3 are prohibited by pressing the prohibition switch 20. The lock knob 23 allows the door 4 to be locked and unlocked freely. Moreover, when a person who remains in the vehicle opens the door 4 and gets off, the prohibition is lifted.

For example, when the prohibition switch 104 is pressed, the power of the slave unit 1B is turned off, the reception function is activated and the transmission function is turned off, and an invalid code is added to the transmission signal (ID code). Is possible. This corresponds to the case where there are a plurality of slave units 1B. That is, when the spare slave unit 1B is used in addition to the slave unit 1B to be used, the door 4 is unlocked by the spare slave unit 1B if the prohibit switch 104 is pressed to make the master unit uncontrollable. It can be placed in the car because it does not operate. When the child device 1B is lost or the used child device 1B runs out of battery, it is prohibited by pressing any switch (for example, the reset switch 103) of the auxiliary child device 1B. Switch 104
Can be released and enabled.

In order to prevent confusion when a plurality of slave units 1B can be used at the same time, each slave unit 1B is given a priority and the slave unit 1B having a higher priority is within the reception range of the master unit. The prohibition switch 104 of the handset 1B may not be released when the user is in the room. For example, the prohibit switch 10
When the time sequence in which 4 is pressed is later, the priority order is set higher, and even when the prohibition switch 104 is released, it can be released only from the highest priority order (L
IFO; Last-in first-out method).

In the above embodiment, the cordless switch is provided with the lock switch and the unlock switch, but it is also possible to use one switch for both lock and unlock, and switch between lock and unlock each time the button is pressed. Further, even when a lock switch and an unlock switch are provided on the slave unit to enable manual operation, the master unit may prohibit automatic locking and unlocking.

In each of the above-mentioned embodiments, the means for prohibiting the automatic locking / unlocking have been individually described. However, the means for prohibiting the automatic locking / unlocking may be combined as appropriate. Good. For example, if a prohibition switch and an ignition key insertion switch are provided and whether the prohibition switch is turned on or the ignition key insertion switch detects a key, in either case, the prohibition processing unit prohibits automatic locking and unlocking. can do.
