3 and 4 are flow charts for explaining the operation of the portable device and the controller, respectively. Hereinafter, FIG.
The operation of this embodiment will be described in detail with reference to FIGS.

When the lock switch 101 of the portable device is pressed, the control device 103 detects it (step 30).
1) The lock control signal is output to the transmission device 106 (step 305). The lock control signal is a serial signal including the secret code stored in the storage device 104 and the code representing the lock command. At the same time, the storage device 105 stores that the lock switch 101 has been operated, that is, that the lock command has been output (step 306). The transmitter 106 modulates the lock control signal and wirelessly outputs it as a control signal from the transmitting antenna 109.

The control signal is received by the receiving antenna 201 of the controller. The receiving device 203 demodulates this,
Output to the control device 207. The control device 207 compares the personal identification code in the control signal received from the receiving device 203 with the personal identification code stored in the storage device 205, and confirms that they match (steps 401 and 402). If they match, it is determined that the control code is a code indicating locking (step 403), and the actuator 2
A lock signal is output to 08 (step 404). The actuator 208 drives and controls a door lock mechanism (not shown) to a locked state.

When the detection switch 209 ₁ detects that the door lock mechanism is locked (step 4).
05), the control device 207 outputs a lock completion signal indicating that the lock is completed to the transmission device 204 (step 40).
6). The transmitting device 204 modulates the signal and sends it as a response signal via the transmitting antenna 202. The response signal is a signal in which a personal identification code and a code indicating that the door lock mechanism is locked are connected in series.

After the response signal is received by the receiving antenna 110, it is demodulated by the receiving device 107, and the control device 1
03 is output. The control device 103 determines whether or not the received response signal is a signal indicating completion of locking (step 30).
7, step 309), in the case of the signal indicating the completion of locking, the stored contents of the storage device 105 and the contents of the response signal are compared (step 310). When the two have a predetermined relationship, for example, when the two match, a locking completion notification signal indicating completion of locking is output to the notification device 108 (step 31).
1). If the response signal is not received within the predetermined time, the operation ends (step 308).

The notification device 108 responds to the lock completion notification signal to notify the user that the door is locked by the LED or the buzzer. That is, when the locking switch 101 for locking is operated and a response signal indicating that the lock is applied is received, the notification device 108 notifies the user that the locking is completed.

When the unlock switch 102 is operated without operating the lock switch 101 (steps 301, 3)
02), the control device 103 outputs an unlocking control signal for instructing unlocking (step 303), and stores in the storage device 105 that the unlocking switch 102 has been operated, that is, the unlocking command has been transmitted. (Step 304). Transmitter 10
6 transmits a signal indicating an unlock command as a control signal via the transmitting antenna 109.

Subsequent operations of the controller are the same as those in the case of locking (steps 401 to 403 and steps 407 to 410). That is, the actuator 2
In response to the unlock signal from the control device 207, 08 controls the door lock mechanism to the unlocked state. Detection switch 20
9 ₂ detects that the unlocking operation has been completed, and a response signal indicating that the unlocking operation is completed is transmitted via the antenna 202 to the transmitting device 20.
Sent from 4. The same operation as the locking operation is performed on the portable device side (steps 307, 309, 312, 313 and 314). That is, the control device 103 controls the receiving device 10
It is determined whether or not the content of the response signal received in 7 and the content stored in the storage device 105 have a predetermined relationship, for example, if they match, and if they match, a notification signal is output to the notification device 108. To do. The notification device 108 responds to this by
An LED or buzzer notifies the user that the door has been unlocked. As a result, when the unlocking operation switch 102 is operated and a response signal indicating that the lock has been unlocked is received, the user is notified that the unlocking has been completed.

[0022] In the case where the door lock mechanism when operating the lock switch 101 or the unlock switch 102 is in the half-door state, detects that the detection switch 209 ₃ is turned on, the control device A half door signal indicating a half door is output from 207. When the portable device receives the signal indicating a half-door, the control device 103 determines that the door is a half-door (step 315) and outputs a half-door alarm notification signal indicating the half-door. In response to this, the notification device 108 notifies that the door is a half-door.

Next, when the content of the response signal is changed in the middle of being returned from the main body device due to radio interference or the like, for example, the lock switch 101 of the portable device is operated, and the main body device completes the lock control operation. After that, when the response signal changes due to radio wave interference or the like and the portable device receives the unlock completion response signal despite the transmission of the lock completion response signal (step 307), the reception code is unlocked. This is a signal indicating completion (steps 309 and 312), while the storage device 1
The contents indicating the lock are stored in 05, and the contents of the both are different, so no notification is given (step 313). After operating the unlocking / locking switch 102 of the portable device and completing the unlocking control operation in the main body device, the response signal changes due to radio wave interference or the like even though the unlocking completion response signal is transmitted, but the portable device When the lock completion response signal is received, the same operation is performed (steps 307, 309, 310). Therefore, the user can know that the control operation according to the operation may not be completed because the notification is not made despite the operation of the portable device. Therefore, if the same operation is performed again and the notification according to the operation is given, it is possible to confirm that the desired control operation is completed.

As described above, according to this embodiment,
When the portable device receives a response signal indicating that the lock switch 101 has been operated and locked, or when the response signal indicating that the unlock switch 102 has been operated and unlocked, that is, the portable device. It is possible to notify the user that the desired control operation has been completed, only when the operation and the content of the response signal have a predetermined relationship, for example, when they match. Therefore, when the operation by the portable device and the content of the response signal are different, such as when the response signal indicating the completion of the unlocking operation is received despite the locking operation by the portable device, the completion of the control operation is notified. Therefore, it is possible to prevent erroneous notification, and it is possible to provide a two-way remote control device with a more reliable notification operation. In addition, since the notification operation is more reliable, it is possible to provide a safe two-way remote control device for preventing theft.

In the present embodiment, when the operation contents of the portable device and the contents of the response signal do not match due to radio wave interference or the like, no notification is given. It is also possible to make a notification by 108. In addition, in the present embodiment, an example in which the vehicle door is locked and unlocked has been described. However, the vehicle engine is started, the house door is locked and unlocked, or the TV is turned on / off.
The present invention can be applied to a remote control device that wirelessly remotely controls various controlled devices such as turning off and switching channels.

Further, in the present embodiment, an example in which one kind of fixed code is used as the personal identification code has been described, but a code that changes each time an operation switch such as a lock switch or an unlock switch is operated, or a predetermined code. It is possible to use various codes such as a code that changes every number of times of operations, a code that changes every predetermined time, a code created by a random number, or a code that changes using a predetermined function.
