Abstract
Description
Claims (2)
- 차량의 브레이크가 작동하여 에지가 발생하면 상기한 에지중에서 최근에 발생된 몇 개의 에지를 추출하여 상기한 에지들의 평균값을 계산하는 단계와,상기한 에지들의 평균값과 현재 발생된 에지의 폭을 비교하여 에지의 폭이 일정 이하가 되면 크립노이즈 발생을 판단하는 단계로 구성함을 특징으로 하는 휠 스피드센서의 크립 노이즈 검출 방법.
- 제1항에 있어서,상기한 에지의 평균값을 구하는 것은 하이 에지 Ta와 로우 에지 Tb로 구분하여 평균값을 계산하고 현재 출력되는 에지의 하이에지Tc와 로우 에지Td의 폭을 각각 비교하는 것을 특징으로 하는 휠 스피드센서의 크립 노이즈 검출 방법.
