Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for controlling locking / unlocking of a vehicle, a front door or the like from a remote position, and more particularly to a remote control device having a code registration function.

[0002]

2. Description of the Related Art Generally, a remote control device comprises a transmitter for transmitting a unique personal identification code via a medium such as light or radio wave, and a receiver to which the same personal identification code is given. There is. For example, in a keyless entry device for an automobile, which is a kind of remote control device, when a user operates an operation switch of a transmitter, a unique code code is modulated and output from the transmitter. The receiver demodulates the received signal, compares the personal identification code from the transmitter with the personal identification code on the receiver side, and when both match, outputs a control signal according to the operation of the transmitter. The actuator locks or unlocks the door in response to the control signal.

By the way, when purchasing a car employing a keyless entry device, a car in which a unique personal identification code is stored in advance is purchased, and the personal identification code of the transmitter is purchased according to a predetermined registration mode. It is necessary to register in the storage device provided in the receiving device.

In this type of keyless entry device, assuming that the family uses individual transmitters, a plurality of transmitters having different personal identification codes can be used, and the receiver has a storage device. Allows multiple PIN codes to be registered. The user needs to purchase the required number of transmitters and register the personal identification code assigned to each transmitter according to a predetermined procedure.

On the other hand, in recent keyless entry devices, there is a device in which the door is locked / unlocked by a transmitter and the positions and angles of the seats and mirrors can be automatically adjusted to an optimum state for the driver. is there.

In the keyless entry device described above, each personal identification code and the corresponding personal code representing the position of the seat are stored in the storage device on the receiver side. In the receiver, the personal identification code received from the transmitter is compared with the personal identification code stored in the storage device, and when the two coincide, the position of the sheet and the like are automatically adjusted by the personal code stored corresponding to the personal identification code.

When the personal identification code and the personal code are stored in the storage device of the receiver, first, the receiver side is set to the registration mode and the transmission switch of the transmitter is operated to transmit the personal identification code to the receiver side. To do. On the receiver side, the personal identification code is stored in a storage device, and the position of the sheet at that time, the angle of the mirror, and the like are stored as a personal code in a storage area corresponding to the personal identification code.

In the conventional keyless entry device, if three transmitters can be stored in the storage device on the receiver side, the registration area 1 of the storage device on the receiver side can be used.
→ Registration area 2 → Registration area 3 → Registration area 1 → Registration area 2
.. and so on, the rotation update registration method in which registration is overwritten in order is adopted. For example, transmitter A,
When the owners of transmitters B and C have their seats adjusted and the secret code is registered, the secret code of transmitter A and the position of the seat are registered in registration area 1. Etc., a personal identification code a of the transmitter B is stored in the registration area 2, a personal code b is stored in the registration area 2, and a personal identification code c of the transmitter C is stored in the registration area 3. It

[0009]

However, in the above-mentioned keyless entry device, a transmitter having a registered personal identification code, such as when it is desired to change a personal code such as registered sheet information or mirror information. You may want to re-register depending on.

Since the registration is a rotation update registration method, when the personal code b corresponding to the secret code of the transmitter B is changed, the secret code of the transmitter B and the personal code b'are stored in the registration area 1. Therefore, the registration area 2 and the registration area 3 are not changed. Therefore, since the personal identification code and the personal code b ′ of the transmitter B are stored in the registration area 1 and the personal identification code and the personal code b of the transmitter B are stored in the registration area 2, the transmitter B is stored. When was operated, there was a problem that the sheet was not set at the desired position.

An object of the present invention is to provide a remote control device in which a code is rewritable and a malfunction does not occur.

[0012]

A remote control device according to the present invention comprises a transmitter for transmitting a personal identification code in response to an operation of an operation switch, a personal identification code stored in a storage device, and a personal identification code from the transmitter. And a receiver for outputting a control signal when both of them are in a predetermined relationship, a means for switching the receiver to a registration mode, and
A personal information sensor unit that detects personal information and outputs a corresponding personal code, and in the registration mode, the secret code from the transmitter and the secret code stored in the storage device have a predetermined relationship, and the storage device The personal code stored in the storage device is different from the personal code stored in the personal information sensor section, and the personal code stored in the storage device is rewritten with the personal code from the personal information sensor section.

[0013]

When the operating switch of the transmitter is operated in the registration mode, the receiver compares the personal identification code stored in the storage device with the personal identification code from the transmitter, and the two have a predetermined relationship. When the personal code stored in the storage device and the personal code from the personal information sensor unit are different, the personal code stored in the storage device is rewritten with the personal code from the personal information sensor unit.

The receiving unit 104 of the receiver, via the CPU 106, is a storage device 10 composed of an EEPROM.
5, the interface (I / F) 108 and the DIP switch 107. The receiving unit 104, the storage device 105, and the CPU 106 make up a receiver.
The I / F 108 is an actuator 109 that controls locking / unlocking of the door lock 110 and a door (not shown).
Of the door sensor 111 for detecting opening / closing of the door, the key sensor 112 for detecting whether a key is inserted in an ignition switch (not shown), the actuator 113 for driving the power sheet 117 and the power mirror 118, the power sheet 117 and the power mirror 118. It is connected to a personal information sensor unit 114 including a sheet sensor 115 and a mirror sensor 116 that detect an angle and the like. The storage device 105 has three registration areas 1, 2, 3 for storing a personal identification code and a personal code.

FIG. 2 is a flow chart for explaining the operation of CPU 106. In the remote control device configured as described above, first, the door lock / unlock,
The operation when controlling the power seat and the power mirror using the transmitter 101 will be described.

As an initial state, the DIP switch 107
Is open, the door is closed, the key is not inserted in the ignition key cylinder, that is, the reception mode. In addition, in the registration areas 1 to 3 of the storage device 105, personal codes are stored in the personal identification codes of the transmitters 101 to 103 and the areas corresponding to the personal identification codes, respectively. That is, the transmitter 1 is registered in the registration area 1.
01 secret code and personal code a, registration area 2
And the personal identification code b of the transmitter 102,
It is assumed that the secret code C and the personal code c of the transmitter 103 are stored in the registration area 3.

When the unlocking operation switch of the transmitter 101 is operated in this state, the secret code of the transmitter 101 is modulated and output. The receiving unit 104 demodulates the received signal and outputs the secret code of the transmitter 101. CPU10
6 compares the demodulated personal identification code with the personal identification code in the storage device 105. The personal identification code corresponding to the personal identification code of the transmitter 101 is stored in the registration area 1, and since it coincides with the personal identification code of the area, an unlock control signal is output to the actuator 109. Actuator 109
Responds to this by driving the door lock to the unlocked state.

At the same time, the CPU 106 causes the I / F 108
A control signal corresponding to the personal code stored in the registration area 1 is output to the actuator 113 via.
The actuator 113 adjusts the position, angle, etc. of the power sheet 117 and the power mirror in response to the control signal. By the above operation, the door is driven to the unlocked state, and the power seat 117 and the power mirror 118 are set at the position and angle suitable for the user of the transmitter 101.

When the door is locked, if the lock operation switch of the transmitter 101 is operated, the CPU 106 discriminates the coincidence of the secret codes and outputs a control signal. The actuator 109 responds to the control signal by the door lock 1
Drive 10 into the locked state. Even when the transmitters 102 and 103 are operated, the door is locked / unlocked by the same operation, and the power seat 117 and the power mirror 1 are placed at the positions and angles corresponding to the transmitters 102 and 103.
18 is set.

Next, the operation of registering a code in the receiver will be described. When registering a code, first, the DIP switch 107 is closed and the door is opened, and the key is inserted into the ignition key cylinder. As a result, the mode shifts to the registration mode, and the secret code and the personal code can be registered in the storage device 105.

First, the case where no code is registered in the storage device 105 will be described. When the unlocking operation switch of the transmitter 101 is operated, the receiving unit 104 demodulates the received radio wave, and the demodulated personal identification code is sent to the CPU 106.
Output to. As shown in FIG. 2, the CPU 106 determines whether or not the demodulated personal identification code and the personal identification code are registered in the registration area 1 of the storage device 105 (step 20).
1). If it does not exist, the registration area 2 and the registration area 3 are discriminated in this order (steps 203 and 206). The personal code is registered and registered in the corresponding area (step 20).
9). The personal code registered at this time is information on the position and angle of the power sheet 117 and the power mirror 118 detected by the sheet sensor 115 and the mirror sensor 116. The same operation is performed when registering using the transmitters 102 and 103.

Next, in the storage device 105, the secret code of the transmitter 101 and the corresponding personal code are stored in the registration area 1, and the secret code of the transmitter 102 and the corresponding personal code are stored in the registration area 2. Registration area 3
The personal identification code of the transmitter 103 and the corresponding personal code are stored in, and the operation when changing the personal code corresponding to the transmitter 101 will be described.

In this case, the angles of the power seat 117 and the power mirror 118 are changed, and the unlock operation switch of the transmitter 101 is operated in the registration mode. After confirming that the personal identification code is stored in the registration area 1 in the same manner as described above (step 201), the CPU
It is confirmed that the received personal identification code matches the personal identification code stored in the registration area 1 (step 202).

Next, the personal code stored in the registration area 1, the sheet sensor 115 and the mirror sensor 116.
Compare with the personal code obtained from (Step 2
04) If they do not match, only the personal code in the registration area 1 is rewritten by overwriting (step 215). After the registration is completed, an end signal is output (step 217). The actuator 109 locks / unlocks the door lock 110 several times in response to the end signal. The operator can confirm that the registration has been completed by the movement of Innanobu.

Next, a case will be described in which the registration codes other than the transmitter 101 are deleted from the state where the codes corresponding to the transmitters 101, 102 and 103 are registered in the registration areas 1, 2 and 3, respectively. This can be done by operating the unlocking operation switch of the transmitter three times in succession in the registration mode.

That is, in the initial state, the three consecutive flags of each registration area are 0. If the unlocking operation switch of the transmitter 101 is operated once in this state, step 2
Through 01, 202, 204 and 211, the 3 consecutive flags of the registration area 1 are set to 1 (step 213).
When the second operation of the unlock operation switch is performed,
Similarly to the above, through steps 201, 202, 204 and 211, the 3 consecutive flags of the registration area 1 are set to 2 (step 213). When the third operation of the unlocking operation switch is performed, steps 201, 202,
At 204 and 211, since the 3 consecutive flag of the registration area 1 is set to 2, the 3 consecutive flag of the registration area 1 is set to 0 (step 212) and the registration areas 2 and 3 are also set.
Clear the personal identification code and personal code (step 214). After setting the three consecutive flags of the registration areas 2 and 3 to 0 (step 216), an end signal is output (step 217), and the erase operation is ended.

According to the present embodiment, the receiver is in the registration mode, and the secret code transmitted from the transmitter is stored in the storage device 10.
Since the personal code is stored in the area corresponding to the personal identification code when it coincides with the personal identification code stored in 5, there is no inconvenience that a plurality of personal codes exist corresponding to one personal identification code. Therefore, it is possible to prevent the occurrence of malfunction, and it is very convenient.

In this embodiment, the transmitters 101 to 10 are used.
Although the personal code is rewritten when the personal identification code of No. 3 and the personal identification code stored in the storage device 105 match, it is not always necessary to match them and may be rewritten when a certain relationship is established. Good. Further, as a means for switching to the registration mode, the DIP switch 107
