In addition, in describing the component of this invention, terms, such as 1st, 2nd, A, B, (a), (b), can be used. These terms are intended to distinguish the constituent elements from other constituent elements, and the terms do not limit the nature, order or order of the constituent elements. When a component is described as being "connected", "coupled", or "connected" to another component, the component may be directly connected to or connected to the other component, It should be understood that an element may be "connected," "coupled," or "connected."

Next, a vehicle control terminal according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a vehicle control module mountable on a vehicle according to a first embodiment of the present invention. As shown in FIG. 1, the vehicle control module 210 according to an exemplary embodiment of the present invention may include a first antenna unit 211, a second antenna unit 213, an antenna selector 215, and a blue tooth. Module 217 and control unit 219. At this time, in the embodiment of the present invention, the vehicle control module 210 may be mounted on the vehicle 200.

The first antenna unit 211 has a first communication distance, and the second antenna unit 213 has a second communication distance greater than the first communication distance. In the embodiment of the present invention, the first communication distance is a distance that the vehicle control module 200 can transmit and receive a radio signal to and from the terminal 100 such as a smart phone through the first antenna unit 211. 2 The communication distance may be a distance that the vehicle control module 200 can transmit and receive a radio signal to the terminal 100 through the second antenna unit 213.

The antenna selector 215 selects one of the first antenna unit 211 or the second antenna unit 213 to transmit and receive a radio signal through either the first antenna unit 211 or the second antenna unit 213. Choose. In an embodiment of the present invention, the antenna selector 215 may include an RF switching IC.

The Bluetooth module 215 communicates with the Bluetooth module 140 of the terminal 100 through one of the first antenna unit 211 or the second antenna unit 213.

At this time, the Bluetooth module 217 controls the antenna selector 215 and connects the communication with the Bluetooth module 140 of the terminal 100 through the second antenna unit 213 having a large communication distance. The Bluetooth module 140 of the terminal 100 transmits a search signal such as a paging signal or a separate proximity check signal through the first antenna unit 211 having a small communication distance. If it is determined that the Bluetooth module 140 of the terminal 100 is in the first communication distance and outputs the terminal presence signal.

For example, the Bluetooth module 217 causes the antenna selector 215 to select the second antenna 213 and is connected to the Bluetooth module 140 of the terminal 100 at a long distance. As described above, while the Bluetooth modules 217 and 140 of the vehicle 200 and the terminal 100 are connected, the Bluetooth module 217 causes the antenna selector 215 to perform twice per second and 20 ms per time. The first antenna unit 211 is selected and a search signal is output through the first antenna unit 211. As such, when the terminal 100 is located in the short range area, the Bluetooth module 217 receives the response signal for the search signal from the Bluetooth module 140 of the terminal 100 when the Bluetooth module 217 receives the first antenna unit 211. ) Determines that the terminal 100 is located in the short range area and outputs a terminal presence signal.

The control unit 219 controls the door lock driving unit 230 of the vehicle 200 when the terminal presence signal is input from the Bluetooth module 217 to unlock the door 240, and if the terminal presence signal is not input, the door lock driving unit ( 230 to maintain the locked state of the door 240. When the door 240 is unlocked, the user can start the vehicle.

At this time, if the terminal presence signal is not input, the control unit 219 maintains the lock state of the door 240 and at the same time cuts off the power supply 250 of the vehicle 200 or blocks the start of the vehicle 200. Turn off the switching unit 270, which supplies power to the various devices 260, such as the device 261. In addition, when the terminal presence signal is input, the controller 219 turns on the switching unit 270 that supplies the power 250 to the various devices 260 of the vehicle 200 while releasing the lock state of the door 240. Let's do it.

When the terminal presence signal is not input as described above, the control unit 219 maintains the lock state of the door 240 and simultaneously cuts off the power supply 250 of the vehicle 200. Even if the door 240 of the 200 is forcibly opened, starting of the vehicle may not be prevented and vehicle theft may be prevented.

Next, with reference to the drawings will be described in detail the operation of the vehicle control module 210 according to an embodiment of the present invention.

2 is a flowchart illustrating an operation of a vehicle control module according to an exemplary embodiment of the present invention.

First, the connection between the Bluetooth modules 217 and 140 is made (S210). That is, the Bluetooth module 217 performs an inquiry procedure for searching for the Bluetooth module 140 of the terminal 100 existing in the vicinity. After the inquiry procedure, the Bluetooth module 217 performs a pairing procedure to permit communication between the Bluetooth modules 140 of the searched terminal 100. Thereafter, the Bluetooth module 217 performs a paging procedure of attempting a communication connection with the Bluetooth module 140 of the terminal 100 that is allowed to communicate based on the information obtained through the inquiry and pairing procedure. Perform the connection. As described above, in the embodiment of the present invention, the Bluetooth module 217 performs communication connection such as an inquiry procedure, a pairing procedure, and a paging procedure through the second antenna unit 213. Once the pairing procedure has been performed, the Bluetooth module 140 and the Bluetooth module 217 of the terminal 100 may be omitted in a subsequent Bluetooth communication process.

After the Bluetooth module 217 is connected to the Bluetooth module 140 of the terminal 100 through the second antenna unit 213, the Bluetooth module 217 is the first antenna unit 211 having a small communication distance during a periodic search period. The search signal is transmitted through the controller to determine whether the Bluetooth module 140 of the terminal 100 is within the first communication distance (S220).

At this time, when the Bluetooth module 217 receives the response signal for the search signal from the Bluetooth module 140 of the terminal 100 through the first antenna unit 211 during the search period, the Bluetooth module 217 is connected to the terminal 100. The terminal 100 determines that the terminal 100 is in the short range region, that is, the first communication range region, and outputs a terminal presence signal (S230).

When the controller 219 receives the terminal presence signal from the Bluetooth module 217, the controller 219 controls the door lock driving unit 230 of the vehicle 200 to unlock the door 240 (S240).

If the Bluetooth module 217 does not receive a response signal for the search signal from the Bluetooth module 140 of the terminal 100 through the first antenna unit 211, the Bluetooth module 217 may be configured to be a short-range region of the terminal 100. That is, it is determined that there is no terminal 100 in the first communication distance region, and does not output the terminal presence signal (S250).

If the controller 219 does not receive the terminal presence signal from the Bluetooth module 217, the controller 219 controls the door lock driver 230 to maintain the locked state of the door 240 (S260).

The Bluetooth module 217 causes the antenna selector 215 to select the second antenna unit 213 during a period other than a search period after communication with the Bluetooth module 140 of the terminal 100 is performed. Accordingly, the Bluetooth module 217 and the Bluetooth module 140 of the terminal 100 may maintain a communication connection state. As described above, in the embodiment of the present invention, the communication distance of the first antenna unit 211 is shorter than that of the second antenna unit 213. To this end, the first antenna unit 211 may include a load connected between the antenna of the first antenna unit 211 and the antenna selector 215.

As such, when the communication distance of the first antenna unit 211 is shortened by the rod, the communication distances of the antennas of the first antenna unit 211 and the second antenna unit 213 may be the same. When the communication distances of the antennas of the first antenna unit 211 and the second antenna unit 213 are the same, the manufacturing of the vehicle control terminal 100 may be simplified and the manufacturing cost competitiveness may be improved due to the mass purchase of the parts.

As described above, the vehicle control module 210 according to the embodiment of the present invention may communicate with the terminal 100 at a short distance as well as at a long distance. Therefore, the user can control the door lock as soon as the user approaches the vehicle without the inconvenience of spending time for the Bluetooth modules 140 and 214 to communicate after accessing the vehicle.
