It can be easily inferred by the average expert in the art.

The wakeup module 251 controls the transmitter 210 to transmit the wakeup data (WakeUp_Data) to the remote controller 100.

When the remote controller 100 responds, the wakeup module 251 controls the receiver 230 to receive response data about the wakeup data.

The wakeup module 251 determines whether the response data to the wakeup data is received. In response to receiving the corresponding response data, the wakeup module 251 notifies the fact to the access module 253. On the other hand, when the response data is not received, the wakeup module 251 controls the transmitter 210 to retransmit the wakeup data to the remote controller 100.

5 is a flowchart illustrating an authentication method of an automobile user using low power RFID communication according to an exemplary embodiment of the present invention. The wakeup data (WakeUp_Data) is transmitted to the receiver 110 of the remote controller 100 through the transmitter 210 of the transceiver controller 200 (S301). The wakeup data may be periodically transmitted for 10 ms once every 1 second to 3 seconds using an electromagnetic wave having a low frequency (hereinafter, referred to as 'LF') 20khz.

On the other hand, although not shown in the figure, when using a plurality of remote controller 100, the transmission unit 210 of the transmission and reception controller 200, the identification after transmitting the wake-up data for the specific remote controller 100 authentication ID code authentication data may be transmitted to the corresponding remote controller 100 with authentication data including a small number of bits set among unique ID codes for each remote controller 100 stored in the unit 290.

Accordingly, when the remote controller 100 receives the wake-up data and the wake-up data / ID code authentication data in step S301, the remote controller 100 transmits the response data to the transmission / reception controller 200.

At this time, the transmission and reception controller 200 determines whether response data is received from the remote controller 100 (S303).

As a result of the determination, when the transmission / reception controller 200 does not receive the response data, it returns to step S301 and transmits the wake-up data.

On the other hand, when the remote controller 100 receives the wake-up data of the transmission and reception controller 200, the remote controller 100 transmits the response data for confirming the proximity to the transmission and reception controller 200 (S305). That is, the remote controller 100 may transmit data for checking proximity to the transmission / reception controller 200 for 50 ms with a low frequency of 447.7mhz of ultra high frequency (UHF).

After operation S350, the transmission / reception controller 200 determines whether response data for data for checking proximity is received from the remote controller 100 (S307).

On the other hand, when the determination result, the transmission and reception controller 200 receives the response data for the data for checking the proximity to the remote controller 100 to request the authentication data for the proximity check to receive the authentication data (S309).

The transmission / reception controller 200 performs authentication determination using the authentication data received in step S309 (S311).

As a result of the determination, if the received authentication data is not valid authentication data, the transmission / reception controller 200 goes to step S315 to perform security and lock setting.

On the other hand, if it is determined that the received authentication data is legitimate authentication data, the transmission and reception controller 200 releases security and lock (S313).

By sequentially transmitting the wake-up data and the ID code authentication data of the transmission / reception controller as described above, even if a plurality of remote controllers 100 are used, communication crosstalk due to the RF communication can be prevented according to the wake-up signal of the vehicle.

Referring to FIG. 5, the authentication procedure of the present invention is additionally described as an embodiment shown in FIG. 6 according to the authentication method of an automobile user using low power RFID communication according to the flowchart.

That is, the wake up signal does not own an ID which is a unique number, so that when the remote controller 100 receives the wake up signal of the transmission / reception controller 200, the wake up signal is assigned to a unique ID of the remote controller 100. For authentication, the transmission / reception controller 200 transmits an ultra high frequency (UHF) 447.7mhz wireless small output signal and requests the corresponding signal.

In this case, the transmission distance of the wireless low power of the UHF of the remote controller 100 is 20 to 50m, and the communication distance of the low frequency (hereinafter referred to as 'LF') of 2okhz of the transmission / reception controller 200 is 2 to 3m. The distance is not constant.

Accordingly, when the multiple vehicles are in close proximity as shown in FIG. 6, a wake up signal transmitted by the “A” transmission / reception controller 200 is generated, and the remote controller 100 of the “B” is in close proximity to the wake up signal. Recognizing and transmitting the ID authentication request signal for the "B" to the wireless output power, since the communication distance of the wireless small output is not constant, a phenomenon occurs that the transmission and reception controller 200 of the adjacent "B" operates.

In order to prevent the malfunction, a repeat authentication scheme is applied, that is, the transmission / reception controller 200 and the remote controller 100 compare the same ID and authenticate according to the same.

That is, while transmitting and receiving a wake-up signal at a predetermined period of about 1 to 3 seconds in the transmission and reception controller 200 of "A", the remote controller 100 of "A" is repeatedly inquired within a predetermined time. ) How to check and authenticate.

If the remote controller 100 of the " B " sends the corresponding ID to the wake up signal transmitted from the transmission / reception controller 200 of the " A " and requests the operation of the transmission / reception controller 200 of the " B " Will occur. Accordingly, the transmission / reception controller 200 of the “B ^” is “low frequency (LF)” communication having a transmission distance of 2 to 3m to check whether the remote controller 100 of the “B ^' ” is “ ID transmission request signal is once again transmitted to the remote controller 100 of B ^' ". In this case, "B ^'" of the remote controller 100 does not close ^"B'" of the ID is not sent "B ^'" transmission and reception controller 200 of is no longer operate.

 On the other hand, the ID request data of the remote controller 100 may be variably applied to those skilled in the art to repeatedly transmit the same data information, or to transmit any other data twice.
