Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for opening and closing a vehicle door using Bluetooth,

The present invention relates to an apparatus and method for opening and closing a vehicle door using Bluetooth. More particularly, the present invention relates to an apparatus and a method for remotely controlling lock and unlock of a vehicle door using Bluetooth, and, when a Bluetooth module enters a sleep mode, The present invention relates to an apparatus and method for enabling a user to tag a device and convert a Bluetooth module into a wakeup mode by using communication, and further, to lock or unlock a vehicle door by simply tagging the device.

Bluetooth (Bluetooth) is a typical short distance dedicated communication protocol for exchanging information by connecting portable devices such as mobile phones, notebooks, earphones, and headphones to each other. Bluetooth can provide data, voice, and video transmission / reception services through wireless connection between various communication devices in a PAN (Personal Area Network), a home, an office, and a meeting room within a radius of about 10 m. Bluetooth is cheap and it can be miniaturized, it can output up to 4dBm using 2.4GHz frequency, so it can operate with low power consumption. Therefore, it is widely used such as a telephone, a mobile phone, a notebook, a PDA, a headset, a handsfree, and a remote controller.

Conventionally, when a user unintentionally puts a key in a vehicle cabin and locks the door, there has been an inconvenience that maintenance is required and the vehicle door must be opened. Recently, in order to solve this problem, there has been proposed a technique of using a communication module such as a mobile phone to operate the door locking and unlocking by short distance communication. The most widely used technology for this short distance communication is the Bluetooth technology introduced above.

However, if the Bluetooth is not used after the network is established, it can be automatically switched to the sleep mode to reduce power consumption. SLEEP mode is a mode to temporarily shut down the Bluetooth network to minimize the power used to maintain the Bluetooth network connection. In this case, the network formed between the master and the slave is interrupted, and no data or signal is transmitted between the master device and the slave device. Here, the master refers to a device that provides data communication services using Bluetooth technology, and the slave refers to a device that receives services such as data communication from a master. Therefore, in order to connect the Bluetooth network again, it is necessary to switch to the wake-up mode which activates the Bluetooth in the sleep mode. However, conventionally, in order to change the setting in the wake-up mode, the user has to operate the communication module directly and change the setting through the activated communication module.

In order to solve this problem, a technique has been proposed in which a timer is operated to switch from a sleep mode to a wake-up mode automatically after a predetermined time elapses. However, since the use time of the user is irregular, Even if it is not necessary, it becomes a wakeup mode, and power consumption becomes large, which is a problem.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a method for opening and closing a door of a vehicle 1 using Bluetooth according to an embodiment of the present invention.

As shown in FIG. 1, in order to perform a method of opening and closing a door of a vehicle 1 using Bluetooth, the present invention is applied to a device that can be carried by a user and has a BLE (Bluetooth low power: BLUETOOTH LOW ENERGY) A Bluetooth device 20 mounted on the vehicle 1 and having a BLE function and an NFC chip 30 mounted on the vehicle 1 and capable of being recognized by the NFC reader 104. Here, the device 10 includes communication modules such as general mobile phones, smart phones, and PDAs. The Bluetooth device 20 is a device equipped with a Bluetooth module, and refers to a device having another Bluetooth module and a general device forming a Bluetooth network.

Bluetooth technology is a short distance communication technology using frequency 2.4GHz. Bluetooth technology is divided into BT3.0 and BT4.0, BT3.0 is called Bluetooth class, and BT4.0 is called Bluetooth low power or Bluetooth smart. By changing the communication protocol to minimize current consumption, BT4.0 can operate efficiently in battery operated portable devices.

A master is a device that provides services such as data communication using Bluetooth technology, and a slave is a device that receives services such as data communication from a master. To connect the Bluetooth, first turn on the slave and activate the master's Bluetooth function, and the master will search all the slaves in the vicinity. If a slave which is desired to be connected is selected among the searched Bluetooth devices, the master device proceeds with pairing with the selected slave. In the method of pairing between Bluetooth devices, a master device requests an address and an ID of a slave device, and performs a mutual registration process with a Bluetooth device to be connected using the information provided through the request. The master receiving the service request of the slave forms a network for data communication with the slave and provides the corresponding service. In one embodiment of the present invention, the Bluetooth device 20 serves as a master device and the device 10 serves as a slave device.

1, the device 10 includes an input unit 101 through which a user inputs a command, an application 102 that converts and controls the input command into a signal, a Bluetooth device 20 that receives the converted signal, And an NFC reader 104 capable of switching a sleep mode of the Bluetooth device 20 into a wake-up mode. The Bluetooth device 20 includes a second Bluetooth module 201 for receiving the originated signal, a controller 202 for processing and controlling the received signal, a door 202 for opening and closing the door of the vehicle 1 according to the signal, And an opening / closing actuator 203.

As shown in FIG. 1, the user inputs a lock or unlock command of the vehicle 1 door through the input unit 101 of the device 10. At this time, the application 102 installed in the device 10 provides an interface for the user to input a command through the input unit 101, and converts the input command into a signal.

The first and second Bluetooth modules 103 and 201 communicate with each other via a Bluetooth connection according to a Bluetooth protocol. The converted signal is transmitted from the first Bluetooth module 103 installed in the device 10 to the second Bluetooth module 201 in the Bluetooth device 20.

The control unit 202 controls the overall electrical signals and data made in the vehicle 1. [ The control unit 202 includes a module capable of controlling signals and data of an ECU, a microcomputer, a CPU, and the like. When the second Bluetooth module 201 in the Bluetooth device 20 receives the transmitted signal, the controller 202 operates the door opening / closing actuator 203 through the received signal to detect whether the door of the vehicle 1 is locked Or released.

The door opening / closing actuator 203 operates to lock and unlock the door of the vehicle 1 and automatically locks the door of the vehicle 1 after a certain period of time after the door of the vehicle 1 is closed after the door of the vehicle 1 is unlocked .

As shown in Fig. 1, an NFC reader 104 may be mounted on the device 10 to tag the NFC chip 30 mounted on the vehicle 1. [ Near Field Communication (NFC) is one of RFID (Radio Frequency IDentification) technologies in which a device 10 such as a mobile phone, a smart phone, a PDA or the like transmits a signal at a short distance (1 cm to 10 cm) And a data exchange technology for exchanging data between the contactless terminals. In an embodiment of the present invention, when the NFC reader 104 is mounted on the device 10 and the NFC chip 30 mounted on the vehicle 1 is tagged, mutual recognition and data transmission / reception are possible.

As shown in Fig. 1, the vehicle 1 may further include a power source 40, a relay 50, and a memory 60. Fig.

The power source unit 40 may use a separate battery, but may be connected to a battery mounted on the vehicle 1. In this case, a transformer may be further provided if the voltage is not matched. The RELAY 50 controls the power supply to the power supply unit 40 and blocks the power supply to the memory unit 60. The memory 60 can store the authentication information of the first and second bluetooth and the information of the NFC chip 30. [

2 is a flowchart illustrating a process of entering a conventional Bluetooth mode into a sleep mode.

In general, if the network is not used for a certain period of time after the Bluetooth network is connected, the Bluetooth device is switched to the SLEEP mode.

More specifically, as shown in FIG. 2, when the Bluetooth device forms a network (S201), the timer is immediately activated (S203). The timer starts a counter for a predetermined period, and generates a timing signal when the counter ends (S204). After the timer starts to operate, until the timer generates a timing signal, the Bluetooth device enters a wake-up mode in which power is consumed (S202). After the timing signal has been generated, the Bluetooth device determines whether there is data or signal transmission / reception with another Bluetooth device (S205). If there is data or signal transmission / reception, the Bluetooth device transmits / receives data (S206). When data transmission / reception is completed, the timer starts counting from the beginning. On the other hand, if there is no data transmission / reception, the mobile terminal enters the sleep mode, and after entering the sleep mode, the timer operates again to advance the counter from the beginning (S207). In the sleep mode, when there is no mandatory entry instruction by the user in the Bluetooth device, the Bluetooth network is temporarily disconnected and the power consumption is minimized.

On the other hand, the counting time can be made to generate the timing signal at intervals of 0.1 second to 1.5 seconds. Or may generate two or more timing signals per one cycle in other time periods.

When the Bluetooth device enters the sleep mode, the Bluetooth network is blocked, so that data or signals can not be transmitted between the master device and the slave device. Therefore, you must switch from sleep mode to wake-up mode to connect the Bluetooth network again. However, the process of pairing for connection between two Bluetooth devices from the beginning can be omitted. When switched to wake-up mode, the network is reconnected between two Bluetooth devices and data or signals can be transmitted.

1, when the NFC reader 104 is attached to the device 10 and tags the NFC chip 30 mounted on the vehicle 1, the two Bluetooth devices are connected to the wake- Up mode.

3 is a flowchart of a method of opening and closing a door of a vehicle 1 using Bluetooth according to an embodiment of the present invention.

As shown in FIG. 3, the Bluetooth device 20 sends a pairing authentication request to the device 10 (S301). Then, the device 10 provides the pairing authentication response by providing the Bluetooth device 20 with the authentication information such as the address and the ID (S302). After confirming the authentication information of the device 10 (S303), the Bluetooth device 20 and the device 10 perform the mutual registration process using the provided information (S304). The Bluetooth device 20 and the device 10 registered with each other can transmit and receive data and signals by forming a Bluetooth network (S305). And can store both authentication information in the memory 60 for quick connection without a pairing process at a later re-connection.

After the Bluetooth network is formed, a command signal may be transmitted to the Bluetooth device 20 through the device 10 within a predetermined time (S306). At this time, in the manual mode, the command signal is generated as the user inputs a command to lock or unlock the door of the vehicle 1 through the input unit 101 (S307). The command signal applied to the input unit 101 is transmitted from the first Bluetooth module 103 to the second Bluetooth module 201 and the door opening and closing actuator 203 is driven through the control unit 202 The door of the vehicle 1 is locked or released.

In the automatic mode, the command signal is generated according to the degree of sensitivity of the communication signal between the device 10 and the Bluetooth device 20 (S308). If the distance between the two devices is close, the sensitivity of the communication signal is strong. If the distance is long, the sensitivity of the communication signal is weak. The controller 202 of the Bluetooth device 20 determines that the device 10 is located outside a certain radius and transmits a lock signal to the vehicle 1 The door locks. On the contrary, when the sensitivity of the communication signal gradually increases and becomes equal to or higher than the predetermined sensitivity, the control unit 202 of the Bluetooth device 20 determines that the device 10 is located within a certain radius, Release operation. The manual mode and the automatic mode can be set by the user through the device 10.

If there is no command signal to be applied to the Bluetooth device 20 within a predetermined time after the Bluetooth network is formed, the first and second Bluetooth modules 103 and 201 may sleep (SLEEP) according to the procedure shown in FIG. Mode (S309).

As described above, when the Bluetooth device enters the sleep mode, the Bluetooth network is blocked, so that no data or signals are transmitted between the Bluetooth device 20 and the device 10. [ Therefore, you must switch from sleep mode to wake-up mode to connect the Bluetooth network again. The most common method of switching from the sleep mode to the wake-up mode is to transmit the forced weather signal to the Bluetooth device 20 by operating the device 10 directly (S310). When the wakeup mode is switched to, the Bluetooth network is formed again between the first and second Bluetooth modules 103 and 201 so that data or signals can be mutually transmitted and received (S311). In this case, the first and second Bluetooth modules 103 and 201 are switched to the wake-up mode. Therefore, in order to lock or unlock the door of the vehicle 1, the operation is performed as in the process of step S307 or S308 An additional process of applying the command signal is required (S312).

Another method for switching from the sleep mode to the wakeup mode is to tag the NFC reader 104 mounted on the device 10 to the NFC chip 30 mounted on the vehicle 1 (S313). 1, the device 10 equipped with the NFC reader 104 can communicate with the NFC chip 30 through a normal NFC communication method. More specifically, the NFC chip 30 has a unique tag key value. When the NFC reader 104 tags the NFC chip 30 (S313), the NFC reader 104 receives the tag key value of the NFC chip 30, identifies the tag key value, Compare the kit values. If the compared two sets of values match, the NFC reader 104 receives the authentication information of the NFC chip 30 (S314). When the NFC reader 104 receives and confirms the authentication information, the first Bluetooth module 103 in the device 10 is switched to the wake-up mode and at the same time the device 10 automatically transmits the authentication information to the Bluetooth device 20 The second Bluetooth module 201 is also switched to the wake-up mode by sending out a weather signal. Therefore, the first and second Bluetooth modules 103 and 201 can be switched to the wake-up mode only by the user tagging the NFC reader 104 to the NFC chip 30.

When the first and second Bluetooth modules 103 and 201 are in the wakeup mode by the user tagging the NFC reader 104 to the NFC chip 30, the same as when the user inputs the forced wake-up signal An additional process may be required to apply an operation command signal to lock or unlock the door of the vehicle 1, such as the process of step S307 or step S308. The first Bluetooth module 103 installed in the device 10 switches to the wakeup mode and the second Bluetooth module 201 installed in the Bluetooth device 20 receives the forced wakeup signal At the same time, a signal for automatically locking or unlocking the door of the vehicle 1 is transmitted (S315). The first and second Bluetooth modules 103 and 201 are switched to the wakeup mode and the vehicle 1 is locked or unlocked at the same time only by the user tagging the NFC reader 104 to the NFC chip 30. [ can do.

4 is a schematic view showing a state in which the Bluetooth device 20 and the NFC chip 30 are installed in the vehicle 1 and an NFC communication process.

The Bluetooth device 20 is installed inside the vehicle 1, and preferably, as shown in FIG. 4, power is easily supplied from the power source 40, and at the same time, the Bluetooth device 20 can be easily paired with the device 10 It can be installed in the front seat.

The NFC chip 30 is installed inside the vehicle 1 but the NFC chip 30 is installed close to the outside so that the NFC reader 104 can be tagged to the NFC chip 30 from outside, . Therefore, the NFC chip 30 is installed near the outer shape of the vehicle 1, and is preferably installed in the interior of the vehicle 1 door so as to be easily tagged by the user, as shown in Fig.

The process of locking and unlocking the vehicle 1 by NFC communication between the device 10, the Bluetooth device 20 and the NFC chip 30 shown in FIG. 4 is the same as the steps S313, S314, and S315 shown in FIG. 3 same.
