The present invention relates to an apparatus for preventing a relay attack of a vehicle, which comprises: a smart key receiving a low frequency (LF) signal from a smart key system of a vehicle; and the smart key system receiving a radio frequency (RF) signal from the smart key. The smart key system transmits an LF signal having a first structure designated when a PASE mode is activated, and transmits an LF signal having a second structure designated when the PASE mode is deactivated. The smart key receives the LF signal having the first structure and the LF signal having the second structure transmitted from the smart key system and transmits a corresponding RF signal.

    본 발명은 릴레이 어택 방지 장치에 관한 것으로, 차량의 스마트키 시스템으로부터 LF신호를 수신하는 스마트키; 및 상기 스마트키로부터 RF신호를 수신하는 상기 스마트키 시스템;을 포함하며, 상기 스마트키 시스템은, PASE 모드의 활성화 시 지정된 제1 구조의 LF신호를 송신하고, PASE 모드의 비활성화 시 지정된 제2 구조의 LF신호를 송신하고, 상기 스마트키는, 상기 스마트키 시스템에서 송신하는 제1 구조의 LF(Low Frequency)신호 및 제2 구조의 LF신호를 수신하여 이에 대응하는 RF(Radio Frequency)신호를 송신한다.
