  However, in the keyless entry system as described above, when the owner wants to unlock or lock the vehicle or the like, it is necessary to use a transmitter without fail. There is a problem that the key lock cannot be released if it is lost or lost.

  Further, since the transmitter is an electronic device, a power source is required, and since a battery is normally used, it cannot be used when the battery is exhausted. Furthermore, since radio waves and infrared rays are used, there is a problem that the operable radius becomes very short in other transmitters and malfunctions due to interference, in poor places and in climates.

  The present invention has been made for the above-described circumstances, and an object of the present invention is to provide a vehicle, a safe, or an entrance door by inputting a password preset by the owner without requiring a specific transmitter. It is an object of the present invention to provide a vehicle door, safe, or doorway unlocking / locking device that simply and reliably unlocks / locks by using a control unit provided in the door.

  The object of the present invention is provided in a vehicle, and includes a sensing unit that senses voice or vibration, and transmits the voice or vibration sensed by the sensing unit to the control unit that authenticates the electronic signal as an electronic signal, This is accomplished by unlocking or locking the vehicle door according to the result of authentication.

  Also, the above object is achieved by the sensing unit sensing a human contact with the vehicle and transmitting the contact as the electronic signal to the control unit.

  The object is also provided in a safe and provided with a sensing unit that senses voice or vibration, and transmits the voice or vibration sensed by the sensing unit as an electronic signal to the control unit that authenticates the electronic signal, This is achieved by unlocking or locking the safe door according to the result.

  Further, the above object is provided at a doorway door installed in a house or a building, and includes a sensing unit that senses voice or vibration, and authenticates the electronic signal using the voice or vibration sensed by the sensing unit as an electronic signal. This is accomplished by unlocking or locking the doorway according to the authentication result.

  According to the vehicle unlocking / locking device of the present invention, the owner can unlock / lock the vehicle, the safe, and the entrance door without having a special unlocking / locking article such as a key. . That is, information such as a personal identification number can be recognized simply by knocking the windshield of the vehicle. For this reason, even when the key is forgotten in the vehicle or in the room, the vehicle can be unlocked and locked promptly without using a special instrument.

  Moreover, there is no need to worry about the battery as in a conventional keyless entry transmitter.

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

  FIG. 1 is an overall view of a vehicle incorporating an unlocking / locking device according to the present invention.

  The vehicle unlocking and locking device is incorporated in the vehicle 1 owned by the owner, and the sensing unit 11 that senses the contact of the owner with the vehicle 1 is installed at a position where the owner can visually recognize it. Is desirable. The sensing unit 11 is connected to a control unit that controls unlocking / locking of the vehicle.

  FIG. 2 is a block diagram of an unlocking / locking device according to the present invention.

  The sensing unit 11 embedded in a position visible to the owner is connected to the control unit 20 by wire. The control unit 20 is installed in the vehicle, and a signal recognition unit 21 for recognizing a signal transmitted from the sensing unit 11 and a password for unlocking / locking the owner are stored therein. Storage unit 23, authentication unit 22 for authenticating the signal and password, unlocking / locking instruction unit 24 for issuing an instruction for unlocking / locking, and unlocking / locking for controlling unlocking / locking An instruction unit 25 is included. The operation control unit 25 is connected to a lock operation unit 30 that actually performs unlocking / locking, and an illumination / sound operation unit 40 that informs the owner of the unlocking / locking visually or audibly.

  FIG. 3 is a flowchart of the unlocking / locking device according to the present invention.

  In this flowchart, for the sake of simplicity, the unlocking operation and the locking operation will be described in the same flow. However, when performing the locking, it is possible to simplify a password, which will be described later, to the extent that malfunction can be prevented.

  When the owner who owns the vehicle 1 wants to unlock and lock the vehicle 1 in step S301, the owner touches the vehicle 1 to input a password. The sensing unit 11 senses vibrations and sounds that the owner of the vehicle 1 touches the vehicle 1 (step S302), and converts them into electronic signals (step S303). For example, when the user knocks on the sensing unit 11 installed on the windshield surface, the sensing unit 11 embedded in the windshield surface senses this by vibration and sound, and the knock has occurred. It transmits to the control part 20 as a 1-byte electronic signal.

  The normal vehicle 1 employs body earthing, and the cathode of the battery is connected to the body. For this reason, the sensing unit 11 senses whether or not the vehicle is touched by measuring a change in current caused by the owner touching the vehicle 1. It may be a current sensing type. In this case, the sensing unit 11 is installed in the metal part of the vehicle 1, and the owner touches this metal part, so that the sensing unit 11 senses a current change, converts it into an electronic signal, and transmits it to the control unit 20. .

  In the control unit 20, the signal recognition unit 21 receives this electronic signal and transmits it to the authentication unit 22 (step S304). Since the user enters a password using the number of times of knocking or touching the vehicle 1, the signal recognition unit 21 receives the number of times of input of the electronic signal (the number of knocks) received from the first signal input. It is best to stock up and send it to the authentication unit 22. Furthermore, a format in which the number of times of input of an electronic signal is transmitted to the control unit 20 when the input is performed twice in a short time in the manner of a double click of the mouse operation may be employed. In other cases, it is defined that the sensing unit 11 can transmit an electronic signal of up to 2 bytes to the signal recognition unit 21. In the case of normal knocking, 1 byte is used, and when there is a specific knocking, 2 bytes are used. An electronic signal may be transmitted to the signal recognizing unit 21, and when the signal recognizing unit 21 receives a 2-byte electronic signal, the number of input of the 1-byte electronic signal stocked may be transmitted to the authenticating unit 22. .

  In this way, in step S305, it is determined whether or not there is an input from the owner. If there is no input, the process returns to step S301 and accepts the input again. Proceed to

  The authenticating unit 22 that has received the number of electronic signals from the signal recognizing unit 21 authenticates the number of times and the password stored in advance in the storage unit (memory) 23 (step S306). In this authentication, it is determined whether or not the number of received electronic signals matches the number of each digit of the personal identification number (step S307). For example, if the stored personal identification number is 4357, authentication is performed when the authentication unit 22 receives the electronic signal received four times, then three times, then five times, then seven times. Advances to step S308. If the authentication is wrong, the unlocking / locking operation is not performed and the process ends (step S309).

  When it is determined that the authentication is correct, the unlocking / locking instruction unit 24 instructs the operation control unit 25 to unlock / lock (step S308). In response to the instruction, the operation control unit 25 takes into consideration the state of the lock, and if the lock is locked, the lock control unit 30 and the lighting / sound operation unit give an instruction to unlock the lock. 40 (step S310).

  In response to the instruction, the lock operation unit 30 performs the unlocking or locking operation, and the illumination / voice operation unit 40 performs the unlocking or unlocking operation using lighting of a tail lamp or the like according to the unlocking or locking, an electronic sound, or the like. The user is informed that the lock has been obtained (step S311).

  FIG. 4 shows an example in which the unlocking / locking device according to the present invention is applied to a safe. In FIG. 4, a sensing unit 53 is provided on the front door 52 of the safe 51, and a control unit is provided inside the safe 51. In addition, the control unit is connected to the sensing unit 53 with a wire, and receives a signal such as a password when unlocking / locking from the sensing unit 53.

  Also in this case, the unlocking or locking operation is performed in accordance with the flowchart of FIG. 3 as in the case of the unlocking / locking device for vehicles. Therefore, even if the owner does not have a key or the like, only by knocking the front door 52 of the safe 51, the detection unit 53 can detect vibrations and voices, and can recognize the personal identification number. In addition, the safe can be unlocked and locked.

  FIG. 5 shows an example in which the unlocking / locking device according to the present invention is applied to an entrance door provided in a house or a building. In FIG. 5, a sensing unit 62 is provided at the entrance door 61, and a control unit is provided inside the entrance door 61. In addition, the control unit is connected to the sensing unit 62 via a wire, and inputs a signal such as a personal identification number for unlocking / locking from the sensing unit 62.
