On the other hand, when the input button 60 is not pressed for a predetermined threshold time in the convenience mode, the mode switching means 71 can automatically switch the convenience mode to the vehicle mode.

As described above, according to the present invention, it is possible to control the switching of the operation mode and the control of the vehicle in each mode and the convenience of the operation in each mode, without adding a separate input button 60 to the smart key, Function can be controlled.

3 is a flowchart illustrating an operation of a wireless data transmission unit provided in a vehicle smart key according to an embodiment of the present invention.

Referring to FIG. 3, an operation of the wireless data transmission unit 20 included in the smart key 100 for a vehicle according to the present invention will be described. First, the wireless data transmission unit 20, Mutual pairing is performed (S310).

At this time, it is possible to perform the pairing by switching at least two input buttons 60 simultaneously after switching the vehicle smart key 100 to the convenience mode through the mode switching means 71. For example, the pairing setting of the vehicle smart key 100 is performed by pressing the input button 63 having the trunk opening function and the input button 64 having the emergency alarm function for emergency alert or emergency notification simultaneously for 4 to 6 seconds . ≪ / RTI >

After the first pairing of the Ave device 1 and the wireless data transfer part 20, the Ave device 1 and the wireless data transfer part 20 are interlocked without any other pairing setting.

Once the pairing is performed in step S310, when the door of the vehicle is opened or a boundary release signal is generated, the wireless data transmitting unit 20 which is in the OFF state is switched to the standby mode in step S320.

When the input button 62 for opening the door of the vehicle is pressed, the control unit 70 transmits a door open command to the electronic control unit 2 of the vehicle, (OFF) state to the stand-by mode when receiving the boundary release signal of the vehicle from the vehicle control unit (2).

Thereafter, when the engine of the vehicle is started or a specific signal (e.g., an "ACC ON" signal) is received from the electronic control unit 2 of the vehicle, the control unit 70 operates the wireless data transfer unit 20, And the AV device is interconnected (S330). As described above, in the preferred embodiment of the present invention, the wireless data transfer unit 20 can be connected to the AVE device 1 of the vehicle via Bluetooth communication.

If the wireless data transfer unit 20 and the AAV device 1 are connected in step S330, the wireless data transfer unit 20 is stored in the data storage unit 10 by the AAV device 1 Music or moving picture data to be transmitted through the Bluetooth communication is reproduced in the AVE device 1 and the driver can select and reproduce the music or moving picture to be reproduced by operating the AVE device 1 have.

Step S330 is continuously performed during the operation of the vehicle, and operation of the wireless data transmission unit 20 is stopped when the operation of the vehicle is terminated (S340). If the wireless data transmission unit 20 continuously operates, the driving power of the power supply unit 30 may be discharged. Therefore, when the vehicle is not in operation, the control unit 70 controls the wireless data transmission unit 20, Is stopped.

The case where the vehicle has been shut down indicates a case where the user turns off the engine start of the vehicle or the door is switched to the locked state after the engine is turned off and the vehicle enters the boundary state. The operation of the wireless data transmission unit 20 can be stopped when the 'start-off signal' or the 'vehicle boundary mode' signal is received from the controller 2. [

In addition, the present invention can also stop the operation of the wireless data transmission unit 20 even when the distance between the smart key and the vehicle exceeds a critical distance.

Accordingly, the wireless data transfer unit 20 is connected to the AVE 1 while the driver prepares for or runs the vehicle, and when the driver stops driving and leaves the vehicle, the operation is automatically stopped. Therefore, the power supply unit 30 Can be efficiently managed without unnecessarily consuming the driving power of the power source.

4 is a flowchart illustrating an operation procedure of a light source unit included in a vehicle smart key according to an exemplary embodiment of the present invention.

Referring to FIG. 4, the operation of the light source unit 20 included in the vehicle smart key 100 according to the present invention will be described. First, the user switches the operation mode of the vehicle smart key 100 from the vehicle mode to the convenience mode S410).

At this time, if at least two input buttons among the input buttons 60 are simultaneously pressed or a specific input button is pressed for a predetermined time or more, the mode switching means 71 switches the vehicle mode of the vehicle smart key 100 to the convenience mode .

For example, the mode switching means 71 may be configured such that the input button 62 for opening the door of the vehicle and the input button 61 for closing the door of the vehicle are pressed simultaneously, or if any one of the two buttons is pressed for three seconds or more, Is pressed for 3 seconds or more at the same time, the operation mode is switched to the convenience mode. When the vehicle smart key 100 is switched to the convenience mode, the battery remaining amount display unit 40 displays the setting of the convenience mode by emitting or flashing red light.

On the other hand, when the vehicle smart key 100 operates in the convenience mode, the function of the vehicle mode may be implemented to be blocked by the control unit 70. [

The light source unit 50 including the pointing means 51 and the light emitting means 52 can be operated by pressing a specific input button 60 when the operation mode of the smart key is the convenience mode. At this time, the pointing means 51 and the light emitting means 52 are individually operated according to the input of the specific input button 60 (S420).

When the input button 63 having the trunk opening function is set, the pointing means 51 operates to output the laser light. While the input button 63 having the trunk opening function is pressed, the pointing means 51 It can be implemented to operate continuously.

In addition, when the input button 64 having the emergency alarm function is pressed, the light emitting means 52 can be operated. Also, in the case of the light emitting means 52, the operation can be continuously performed while the input button 64 having the emergency alarm function is pressed.

When the vehicle is to be controlled using the vehicle smart key 100 operating in the convenience mode, the convenience mode can be switched back to the vehicle mode, and after a predetermined time (for example, 4 to 6 minutes If there is no input for utilizing the convenience function, the mode is automatically switched to the vehicle mode (S430).

Here, when the input button 62 for opening the door of the vehicle and the input button 61 for closing the door of the vehicle are simultaneously pressed, pressed for 3 seconds or more, or any one of the buttons is pressed for 3 seconds or more, (71) switches the convenience mode to the vehicle mode. At this time, when the vehicle smart key 100 is switched to the vehicle mode, the remaining battery level indicator 40 is also switched to display the remaining battery level.

In addition, even when the remaining amount of driving power of the vehicle smart key 100 is equal to or less than a threshold value (for example, 30%), it can be implemented to be forcibly switched to the vehicle mode.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Therefore, the scope of the present invention should not be limited by the illustrated embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
