Description

Description: TECHNICAL FIELD The present invention relates to a vehicle door lock control device that operates a vehicle door lock via a telephone line.

[Related Art and its Problems] Recently, an increasing number of vehicles adopt a so-called centralized door lock system in which all doors can be locked or unlocked by a door lock operation on a driver's seat side.

Such a centralized door lock system is extremely convenient because all the doors can be locked with a single lock operation, but on the other hand, if the ignition key is easily locked with the ignition key in the car, all the locks can be locked. The keys may be locked because the doors are locked.

On the other hand, recently, an on-vehicle telephone device (so-called automobile telephone:
The spread of the service area is expected to become even more widespread.

[Object of the Invention] In view of the circumstances as described above, the present invention makes it possible to operate a door lock via a telephone line, and to cope with a key closing operation without panic. For the purpose of providing.

[Configuration of the Invention] Therefore, a vehicle door lock control device according to the present invention includes an in-vehicle telephone transmitting and receiving device, a signal determining unit that determines whether or not a signal received by the in-vehicle telephone transmitting and receiving device includes identification information; The information collating means for collating the identification information with the predetermined key information, the signal discriminating means and the information collating means are operated and controlled, and the identification information included in the reception signal of the vehicle-mounted telephone transmitting / receiving device matches the key information. And a door lock control means for operating and driving the door lock system based on the identification information.

According to this, the door lock can be operated by calling the vehicle-mounted telephone transmitting / receiving device from the telephone outside the vehicle, connecting the telephone line, and transmitting the same identification information as the predetermined key information.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a functional block diagram of a vehicle door lock control device according to the present invention. As shown in FIG. 1, a vehicle door lock control unit 2 serving as a door lock control means connected to an on-vehicle telephone transmitting / receiving device 1 mounted on a vehicle. The lock system 30 is configured to be controllably driven.

The door lock control unit 2 determines whether or not a signal (operation signal) for instructing a door lock operation is included in a signal received by the vehicle-mounted telephone transmitting / receiving device 1.
And information collating means 4 for collating the operation signal with predetermined key information when the operation signal is included.

In this embodiment, as shown in FIG. 3 which is a more specific configuration diagram, the door lock control unit 2 is integrally formed in the control device 20 of the vehicle telephone device 10. This will be described with reference to FIG. It is needless to say that the door lock control unit 2 may be provided independently, or may be configured integrally with a door lock system 30 described later, and may be appropriately changed.

The in-vehicle telephone device 10 includes a transmitter 11, a receiver 12, and a control device 2.
Consists of zero.

The control device 20 includes a CPU 21 having a RAM 22 and a ROM 23, and controls the operation of the transmitters / receivers 11, 12 as a normal vehicle-mounted telephone (the vehicle-mounted telephone transmitter / receiver shown in FIG. 1 including the transmitters / receivers 11, 12). 1) as well as the function of the door lock control unit 2 in FIG. 1 as described above. The key information to be collated in the information collating unit 3 is stored in the RAM 22.

The control device 20 receives vehicle speed information from the vehicle speed sensor 5, so that the door lock operation via the telephone line cannot be performed during traveling to ensure safety. ing.

Here, the power input circuit of the vehicle telephone device 10 has a relay switch 6 as a power switch for interrupting the circuit.
The relay switch 6 is driven by a control current via a key switch 7 which is turned on when an ignition key of the vehicle is inserted.
That is, the power of the in-vehicle telephone device 10 is turned ON / OFF by inserting and removing the ignition key. If the ignition key is inserted, the power of the in-vehicle telephone device 10 is turned on, and the transmission / reception ( Call).

The door lock system 30 includes a door lock controller 31
Is a so-called power door lock system in which the doors are locked or unlocked by driving door lock actuators 33 via a servo mechanism. The door lock controller 31 is operated by operating the switch 32 or from the control device 20.
The locking or unlocking operation is performed in response to an operation signal input to the device. Further, vehicle speed information from a vehicle speed sensor is input to the door lock controller 31, and all doors are automatically locked at a predetermined vehicle speed or higher based on the input vehicle speed information. I have.

In the vehicle door lock control device configured as described above, if key information is determined in advance and stored in the RAM 22, the vehicle door lock control device can be mounted from the external (general) telephone device 8 as shown in FIG. By calling the telephone device 10 and inputting the key information, the door can be locked or unlocked via the door lock controller 31.

Next, when the door is locked while the ignition key is inserted (so-called closing of the ignition key), the external telephone device 8 calls the vehicle-mounted telephone device 10 to release the lock. The control operation of the control device 20 will be described with reference to the flowchart shown in FIG.

Here, in the present embodiment, the key information is a several-digit personal identification number in which a plurality of numbers are arranged, and the personal identification number is input as a digital signal after connection using a touch-tone telephone line. The control device 20 (door lock controller 2) outputs a lock release signal to the door lock system 30 (door lock controller 31) to unlock the door lock actuators 33.

In this case (ignition key closed), since the ignition key is inserted, the vehicle-mounted telephone device 10 is turned on, and transmission and reception are possible.

At this time, when the in-vehicle telephone device 10 is called from the external telephone device 8, the receiver 12 receives the call and connects the line.
(S1, S2) Next, it is determined whether the signal input from the connected line is a voice signal or a digital signal (S3). If the input is a digital signal, the digital information is in the same digit as the password. Is determined. (S
4) When the input digital information indicates the same digit number, the number information is compared with a password stored in the RAM 22. (S5) When the input information matches the password, the vehicle speed information is read from the vehicle speed sensor to confirm that the vehicle is stopped (vehicle speed: V = 0) (S6), and the door lock system 30 (door lock controller 31). ) To output an unlocking operation signal. (S7) Upon receiving this unlocking operation signal, the door lock controller 31 drives the door lock actuators 33 to unlock, and as a result, the door is unlocked.

The operations S1 and S2 in the flowchart shown in FIG. 4 are performed by the vehicle-mounted telephone transmitting / receiving device 1 in FIG. 1, the operations of S3 and S4 are performed by the signal discriminating unit 3, and the operations of S5 are performed by the information matching unit 4. is there.

Although the above embodiment is an example in which the key information is used as a personal identification number and the personal identification number is input as a digital signal, the present invention is not limited to this. For example, a predetermined word (voice) may be used as the key information. In addition, if the voiceprint is configured to be analyzed, the security can be improved in the sense of preventing theft or the like of the vehicle.

In this embodiment, the lock is only released. However, the lock may be reversed by using a different password, which is more convenient.

[Effects of the Invention] According to the vehicle door lock control device according to the present invention as described above, the door lock can be operated via the telephone line, and the key lock can be performed without panic. It can be and is the most convenient.
