Next, the operation of this embodiment will be explained.

First, the pager receiver 9 is stored in the storage box 8 in the vehicle interior, or inserted into the receiver insertion slot 4 on the back side of the door handle 3 from outside the vehicle. In the latter case, the inserted pager receiver 9 passes through the guide passage 5 and is stored in a receiver storage box 8 provided on the passenger compartment side of the door 2. In this state, press the button of the general wired telephone Tel to press the calling number, and then press the button of the code number corresponding to the desired message signal, for example r00.
6 (decimal number 6)”. Then, a radio wave is automatically emitted from the fixed wireless base station St of the telephone company, and the pager receiver 9 receives the paging signal and the message signal "006" following it. When the pager receiver 9 receives a calling signal, it generates a ringing tone. This ringing tone is detected by sensor lO. The code converter 11 and the control unit 1-3 are powered on and begin to operate according to the output signal from the sensor 10 that detects the ringing tone. Next, pager receiver 9
generates a sound corresponding to the received message signal r006. The sensor 10 that detects this sound converts the detected sound into an electrical signal and transmits it to the code converter 11. By this code converter 11, "006 (decimal number 6)
" is converted into an electric signal, that is, a 4-digit binary digital code signal r0110J for a predetermined operation. This code signal "0110" is transmitted to the control unit S.

Then, the control unit S outputs the code signal "011".
0'', that is, the operation program P stored in the memory, is selected and executed.

- In this embodiment, the operation program P6 is an operation program for remotely unlocking the door lock, and for example, when the driver leaves the car key inside the vehicle and locks the door, This is an operation program executed to remotely control A1 to unlock the door.

In this case, the driver calls the pager receiver 9 and then presses a predetermined code number on the number keyboard 21.

Next, referring to FIG. 5, the operation program P6 for remotely unlocking the door lock will be explained.

The control unit S starts a timer TM in step S1 of FIG. Next, in step S2, it is determined whether the timer TM has counted three minutes or more. Then, after the timer TMI has counted for more than 3 minutes, step S
In step S3, it is determined whether the number pressed on the number keyboard 21 is encoded with the code number, and if it is encoded, the process proceeds to step S4, and it is determined whether or not the timer TM+ has clocked 6 minutes or more. , NO, the output signal is transmitted to the output port O of the control unit S in step S5. This output signal is input to the input circuit 14 from the remote control unrotator signal line u0.

Then, the remote control unlock line U is
It is grounded via ground line LA. When the remote control unlock line U is grounded in this manner, the driver door actuator A1 is activated to unlock the door. Thereafter, the power to the code converter 11 and the control unit S is turned off, and the operation program P6 for unlocking the door ends.

On the other hand, if it is controlled to be N'0 in step S3, step S
Proceeding to step 6, it is determined whether the timer TM has timed 6 minutes or more, and if it is determined to be YES, the process ends without unlocking the door. Further, if it is determined NO in step S6, S3
Return to If the determination in step S4 is YES, the process ends without unlocking the door.

As mentioned above, the driver door actuator L is activated after the timer TMI has counted 3 minutes or more after calling the pager reception a9 inside the car from a telephone set near the car. This is because the time required to return to the parking position was estimated to be 3 minutes.

In this way, by unlocking the door after the vehicle returns to its parking position, it is possible to prevent the vehicle from being stolen. Also, step S3. S4
According to the determination operations in S6 and S6, even if execution of program P6 is started due to input of an erroneous signal, unlocking of the door can be prevented. In this case, in step S3, instead of determining whether the number keyboard 21 has been pressed correctly, it may be determined whether the door handle 3 has been operated (this determination can be made using the door handle operation detector). , based on signals from .

Further, when the user forgets to lock the door and operates the automobile door lock remote control device from the outside, a message signal for selecting and executing the operation program P1 for remotely locking the door lock is transmitted from the button. This operation program P1 is an operation program for remotely locking the door lock, and outputs an activation signal from the output port 0 of the control unit S to the lock signal line L0 for remote operation. When this output signal is input to the input circuit 14 of the door lock control circuit F via the remote control lock signal line L0,
As described above, the remote control lock line L1 is grounded, the driver door actuator 8 is activated, and the driver door 2 is locked.

The above is the operation program P for remote control of the door lock.
P, but the memory M of the control unit S contains various operation programs PI (i.0, 1.
2...) are stored. Then, the aforementioned operation program P6 for remote control of the door lock. Other than PI,
For example, a car light lighting program, a shift lever remote control program, an engine warm-up program,
Various operating programs such as programs for operating vehicle air conditioners are stored in the memory M of the control unit +-S. Then, a predetermined operation program can be selected from among the operation programs stored in the memory M and executed.

That is, when the pager receiver 9 receives a message signal, for example, ro 04J in 10 decimal notation, it selects and executes the operation program P4 for remote control of the shift lever, and receives ``O05'' in decimal notation. If so, select and execute the operating program ps for engine warm-up operation, and if decimal number ro 07J is received, select the operating program P for operating the vehicle air conditioning equipment control circuit. You can make it run. And those operation programs Pi (i・0.1.2
...), if necessary, install appropriate remote control detectors, such as 1 for the handbrake operation detector, 8 for the shift lever parking position detector, or 3 for the engine operation detector (first It is sufficient to input a detection signal from a device such as the one shown in the figure to the control unit S.

Although the embodiments of the remote control device for automobile door locks according to the present invention have been described above in detail, the present invention is not limited to the above embodiments, and there is no deviation from the scope of the present invention as set forth in the claims. Instead, various design changes can be made, and remote control devices for other equipment can also be added to this. For example, as an operating program,
Programs that turn on or flash taillights and blinkers,
It is also possible to store in the memory M of the control unit S a program for sounding the horn or a program for opening and closing the power window glass. Controlling the opening and closing of the power window can be carried out by creating a power window opening/closing electric circuit similar to the electric circuit shown in FIG. 1, in which the actuator At is replaced with a power window opening/closing motor.

Further, the control unit S can also be constructed from an electric circuit that does not use a microcomputer. In addition, the control unit S
When a microcomputer is not used as a 4-digit digital code signal, the code converter 11 outputs a 4-digit digital code signal in response to a message signal received by the pager receiver 9, and converts it into a 4-digit digital code signal. It is also possible to set the voltages to different values, such as 3 volts. Moreover, instead of providing the receiver installation part 8 in the part of the door 2 on the passenger compartment side, it is possible to provide it in another suitable position in the passenger compartment.

Furthermore, as the pager receiver 9, in addition to the one that generates a ringing tone in response to a calling signal, a pager receiver that vibrates in response to a calling signal or lights a predetermined lamp in response to a calling signal may be used. When such a pager receiver is used, it is also possible to use a sensor that detects vibration or light instead of the sensor 10 that detects sound. Furthermore, instead of detecting the signal received by the pager receiver 9 with a sensor and transmitting it to the code converter 11, it is also possible to directly connect the pager receiver 9 and the code converter 11 by a connection line. be.

C4 Effects of the Invention As described above, according to the automobile door lock remote control device of the present invention, by using a pager receiver, there is no need to prepare a remote radio device (it is inexpensive and also saves a large space).
