An indirect tire pressure monitoring device and a method thereof are disclosed. The indirect tire pressure monitoring device according to an embodiment of the present invention includes: a wheel speed sensor that detects the rotational angular speed of a wheel; and an electronic control unit that calculates a difference in the dynamic radius of a tire based on the rotational angular speed detected by the wheel speed sensor, calculates the standard deviation of the difference in the dynamic radius of the tire from the calculated difference in the dynamic radius, determines the installation of a chain on the tire based on the calculated standard deviation of the difference in the tire dynamic radius, and rejects tire pressure determination when it is determined that the chain is installed on the tire.

    간접식 타이어 압력 모니터링 장치 및 방법이 개시된다. 본 발명의 일실시예에 따른 간접식 타이어 압력 모니터링 장치는 바퀴의 회전각속도를 검출하는 휠 속도센서 및 휠 속도센서에 의해 검출된 회전각속도에 기반하여 타이어의 동반경 차이를 산출하고, 산출된 타이어 동반경 차이로부터 타이어 동반경 차이 표준편차를 산출하고, 산출된 타이어 동반경 차이 표준편차를 근거로 타이어에 체인 장착을 판단하고, 타이어에 체인이 장착된 것으로 판단되면, 타이어 압력 판정을 기각시키는 전자제어유닛을 포함한다.
