본 발명은, 전륜 휠에 장착된 제1 휠스피드센서에서 측정된 차량속도가 설정된 기준속도보다 빠른지 판단하는 단계, 상기 차량속도가 상기 기준속도보다 빠르면 제동 상황인지 판단하는 단계, 상기 제동 상황이면, 상기 차량속도에 따라 소정시간 경과 후의 후륜 휠에 대한 추정속도를 산출하는 단계 및 상기 소정시간 경과 후, 상기 후륜 휠에 장착된 제2 휠스피스센서에서 측정된 측정속도와 상기 추정속도를 기반으로, 상기 제1 휠스피드센서에 대한 에러 여부를 확정하는 단계;를 포함하는 휠스피드 센서의 에러 검출방법을 제공한다.

    The present invention provides an error detection method of a wheel speed sensor. The error detection method of a wheel speed sensor comprises: a step of determining that the speed of a vehicle measured by a first wheel speed sensor mounted in a front wheel is faster than the reference speed; a step of determining that a vehicle should be braked when the speed of the vehicle is faster than the reference speed; a step of calculating the estimated speed of the rear wheel after predetermined time is elapsed in accordance with the speed of the vehicle when the vehicle should be braked; and a step of determining whether or not there is an error in the first wheel speed sensor based on the estimated speed and the measured speed measured by a second wheel speed sensor mounted in the rear wheel after the predetermined time is elapsed.
