BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and further aspects of the present invention will become more apparent from the following detailed description of preferred embodiments with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a smart key system capable of blocking fraudulent use according to an embodiment of the present invention.

As shown, the smart key fob includes an input unit 100, a communication unit 200, an LED unit 300, a memory 400, and a control unit 500. The input unit 100 is composed of a plurality of buttons. In one embodiment, the input unit 100 is configured to include a door lock button 110, door open button 120, trunk opening and closing button 130 and the alarm sound generating button 140. The communication unit 200 is a communication means for a smart key system for communication with an electronic control unit (ECU) 600 of a vehicle, and includes an LF antenna and an RF antenna. LED unit 300 is made of LED (Light Emitting Diode), it is a configuration for informing the user of the activation / deactivation state of the smart key through different color light emission. The memory 400 may be a nonvolatile memory as storage means for storing data. The memory 400 stores pattern information used to determine whether to activate the smart key. In one embodiment, the pattern information initially stored in the memory 400, as shown in Figure 2 (A), door lock button 110 → door open button 120 → trunk opening and closing button 130 → alarm sound generating button ( 140) patterns may be stored in order. The pattern information may be changed by the user. For example, as shown in FIG. 2 (B), the door lock button 110 → alarm sound generating button 140 → trunk opening / closing button 130 → door The lock button 110 may be changed in order. The pattern information may be generated in a plurality of cases according to the number of buttons of the input unit 100. For example, when the number of buttons of the input unit 100 is four, the user may have 4 × 4 × 4 × 4 = 256 kinds. One of the patterns may be stored in the memory 400. The controller 500 is a controller for controlling the overall operation of the smart key.

Hereinafter, an overall operation process of a smart key capable of blocking illegal use will be described with reference to FIG. 3. First, if a user's input is not detected through the input unit 100 for a predetermined time (for example, 5 minutes) (S100), the control unit 500 deactivates the smart key (S200). Herein, the deactivation state of the smart key refers to a state in which a corresponding command signal is not transmitted to the electronic control unit 600 of the vehicle through the communication unit 200 even when a button is input. That is, the communication function of the communication unit 200 is deactivated. If there is a button input in the deactivated state (S300), the controller 500 compares the input pattern with the registration pattern stored in the memory 400 (B) of FIG. 2 (S400). If the comparison result is matched, the controller 500 activates the smart key (S500). If there is a button input while the smart key is activated, the controller 500 transmits an operation signal corresponding to the input button to the electronic control unit 600 of the vehicle through the communication unit 200 to control the vehicle.

If the input pattern does not match the registration pattern information, the controller 500 counts the number of times of inconsistency pattern input. When the count number reaches a reference number (for example, five times) (S600), the control unit 500 transmits an alarm sound generation command signal to the electronic control unit of the vehicle through the communication unit 200 (S700). At this time, since the communication function of the smart key is in an inactive state, the controller 500 may temporarily transmit the alarm sound generation command signal to the electronic control unit 600 after activating the communication function. The electronic control unit 600 receives the alarm sound generation command signal and generates an alarm sound according to the command. Thereafter, if the input pattern is the same as the registration pattern, the controller 500 activates the communication unit 200 and transmits an alarm sound generation stop command signal to the electronic control unit 600 of the vehicle. Accordingly, the electronic control unit 600 receives the alarm sound generation stop signal and stops the alarm sound generation according to the command.

On the other hand, the control unit 500 may inform the activated / deactivated state of the smart key through the LED unit 300. For example, if there is a button input in an inactive state, the controller 500 turns on a red LED. On the contrary, if there is a button input in the activated state, the controller 500 turns on the green LED. Therefore, when the red LED is turned on when the button is operated, the user can recognize that the smart key is inactive and needs to input a pattern for switching to activation.

So far I looked at the center of the preferred embodiment for the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
