Description

Vehicle door lock control device and method {VEHICLE DOOR LOCK CONTROLLING APPARATUS AND METHOD}

The present invention relates to a vehicle door lock control apparatus and method for controlling lock / unlock of a vehicle door.

A smart key may control a vehicle start and vehicle door lock / unlock using a wireless communication technology such as low frequency (LF) communication. When the user operates the door lock / release button of the smart key, the smart key transmits a control signal according to the user's operation to the vehicle. At this time, the ECU (Electronic Control Unit) in the vehicle receives the control signal transmitted from the smart key through the antenna installed in the vehicle and locks or unlocks the vehicle door accordingly.

Recently, with the development of IT technology and biometric technology, a method of scanning a fingerprint by mounting a fingerprint sensor in a vehicle or a method of touch inputting a password by mounting a touch panel has been applied.

When fingerprint recognition technology is applied, the driver is free from the inconvenience of having to carry a key, but the driver who does not have a fingerprint is required to use the vehicle or the driver who cannot register a fingerprint cannot register a separate fingerprint. There are disadvantages.

In addition, when a touch input method (capacitance or pressure, etc.) is applied, a touch panel must be mounted on the vehicle door part, which causes a disadvantage of damaging the exterior design of the vehicle.

As the short range communication technology, Bluetooth, Near Field Communication (NFC), Radio Frequency Identification (RFID), Infrared Data Association (IrDA), and / or Low Frequency (LF) may be used.

 The hologram reproducing unit 120 is a device for outputting a hologram virtual input pad and is installed (mounted) on a vehicle door or a side mirror. Here, the virtual input pad may be implemented in the form of a keypad or a keyboard. As shown in FIG. 2, the hologram regenerator 120 includes a laser generator 121, a reflector 122, and a scanner 123.

The laser generator 121 generates laser light using a laser light source.

The reflecting plate 122 reflects the laser light output from the laser generating device 121 to the scanner 123.

The scanner 123 has a specific pattern for generating a hologram virtual input pad. The hologram virtual input pad is generated by interference of light generated when laser light passes through a specific pattern of the scanner 123. The hologram virtual input pad may be implemented as a two-dimensional or three-dimensional virtual input pad.

The motion recognition unit 130 is implemented as a motion recognition camera and recognizes a user's movement. The motion recognition unit 130 is installed side by side on the same line as the hologram playback unit 120 as shown in FIG. The motion recognition unit 130 recognizes a user's finger moving on the virtual input pad. The motion recognition unit 130 obtains the motion information of the user as an image and provides it to the processor 170.

The memory 140 may store software programmed by the processor 170 to perform a predetermined operation. The memory 140 may store map information of the virtual input pad (eg, a keypad data table matching the coordinates of the virtual input pad) and previously registered movement pattern information (eg, a password or a signature).

The memory 140 may include a flash memory, a hard disk, a secure digital card, a random access memory (RAM), a static random access memory (SRAM), a read only memory (ROM). The storage medium may be implemented as at least one storage medium (recording medium), such as a ROM, a Programmable ReadOnly Memory (PROM), an electrically erasable and programmable ROM (EEPROM), an erasable and programmable ROM (EPROM), and a register.

Displays include liquid crystal displays (LCDs), thin film transistor-liquid crystal displays (TFT LCDs), organic light-emitting diode (OLED) displays, flexible displays, One or more of a 3D display and a transparent display may be implemented. The hologram reproducing unit 120 may be used as a display for outputting visual information.

The door controller 160 controls locking or unlocking of the vehicle door. The door controller 160 may be implemented as a body control module (BCM). The door controller 160 is connected to the processor 140 through a vehicle network. The vehicle network may be a controller area network (CAN), a media oriented systems transport (MOST) network, a local interconnect network (LIN), and / or an X-by-Wire (Flexray).

When the processor 170 senses the user, the processor 170 controls the hologram reproducing unit 120 to project the virtual input pad to a predetermined position in front of the detected user. The user inputs a password, a pin number or a pattern for unlocking the door on the virtual input pad output in front of the user.

The processor 170 recognizes a movement pattern of a user's finger moving on the virtual input pad through the motion recognition unit 130. The processor 170 analyzes an image transmitted from the motion recognition unit 130, detects a finger position on the virtual input pad, and checks data mapped to the detected finger position. The processor 170 compares the recognized movement pattern with a movement pattern previously registered in the memory 140. The processor 170 instructs the door controller 160 to release the door lock when the recognized movement pattern and the registered movement pattern match. On the other hand, the processor 170 instructs the door control unit 160 to lock the door if the recognized movement pattern and the registered movement pattern do not match.

For example, when the processor 170 recognizes the movement of the user's finger on the virtual keypad, the processor 170 extracts the coordinates on the virtual keypad according to the movement of the user's finger, and matches the keypad data corresponding to the extracted coordinates. Therefore, the processor 170 may check the password input by the user.

3 is a flowchart illustrating a vehicle door lock control method according to an exemplary embodiment.

Referring to FIG. 3, the processor 170 recognizes (detects) a user located near a vehicle door through the detector 110 (S110). The detector 110 detects a user by using any one of a proximity sensor, an infrared sensor, and short range communication. In addition, the detector 110 may also detect the location of the user.

If the user is recognized, the processor 170 controls the hologram reproducing unit 120 to output a hologram virtual input pad (S120). The processor 170 outputs a virtual input pad at a predetermined position in front of the user based on the position of the user.

The processor 170 recognizes the movement pattern of the user's finger through the motion recognition unit 130 (S130). The motion recognition unit 130 obtains an image of the movement of the user's finger moving on the virtual input pad and transmits the image to the processor 170. The processor 170 analyzes the received image and extracts a coordinate value of a virtual input pad mapped to a position of a user's finger.

The processor 170 checks whether the recognized movement pattern of the user's finger matches the movement pattern previously registered in the memory 140 (S140). In other words, the processor 1800 compares the recognized movement pattern with the previously registered movement pattern.

If the recognized movement pattern matches the previously registered movement pattern, the processor 170 instructs the door controller 160 to unlock the vehicle door (S150).

On the other hand, if the recognized movement pattern and the registered movement pattern does not match, the processor 170 instructs the door control unit 160 to lock the vehicle door and maintains the locked state of the vehicle door (S160).
