According to an embodiment of the present invention, provided is an indirect tire pressure monitoring device for estimating tire pressure from wheel speed. The indirect tire pressure monitoring device comprises: a first wheel speed sensor for detecting a first wheel speed signal of a first wheel; a second wheel speed sensor for detecting a second wheel speed signal of a second wheel; and a control unit for sampling a difference between the detected first wheel speed signal and the detected second wheel speed signal, comparing a noise value of the sampled signal with a preset value, determining whether the driving road surface is a low-friction road surface according to the comparison result, and if the driving road surface is a low-friction road surface, prohibiting tire pressure estimation.

    일실시예에 따른 간접식 타이어 압력 모니터링 장치는 휠 속도로부터 타이어의 압력을 추정하는 간접식 타이어 압력 모니터링 장치에 있어서, 제1 바퀴의 제1 휠 속도 신호를 검출하는 제1 휠 속도센서와, 제2 바퀴의 제2 휠 속도 신호를 검출하는 제2 휠 속도센서 및 검출된 제1 휠 속도 신호와 검출된 제2 휠 속도 신호 간의 차이를 샘플링하고, 샘플링된 신호의 노이즈값과 미리 설정된 값을 비교하고, 비교결과에 따라 주행 노면이 저마찰 노면인지를 판단하고, 주행 노면이 저마찰 노면이면, 타이어 압력 추정을 금지시키는 제어부를 포함한다.
