Claims (5)
- 전자식 주차 브레이크 시스템의 모터에 흐르는 모터 전류의 리플 파형에서 상기 모터 전류의 리플 개수를 검출하고,상기 검출된 모터 전류의 리플 개수와 미리 저장된 모터 회전자의 슬롯 수를 이용하여 모터의 회전수를 추정할 때에, 상기 모터의 회전수는 아래의 [식 1]에 의하여 추정하고,상기 추정된 모터의 회전수를 이용하여 상기 전자식 주차 브레이크 시스템의 제동력을 제어할 때에, 주차케이블이 당겨지거나 밀려진 길이를 확인할 수 있도록 상기 모터의 회전수를 이용하고 상기 전자식 주차 브레이크 시스템의 제동 또는 해제 시 상기 모터의 회전수를 기초로 하여 브레이크 디스크와 브레이크 패드 사이의 거리에 대한 제동력을 제어하는 전자식 주차 브레이크 시스템의 제동력 제어방법.[식 1]Rev = N × 1/NT여기서, Rev는 추정되는 모터의 회전수, N은 모터의 전류 리플 개수, NT는 모터 회전자의 슬롯 수이다.
- 삭제
- 제 1 항에 있어서,상기 전자식 주차 브레이크 시스템의 모터에 흐르는 상기 모터 전류의 리플 개수를 검출하기 전에 상기 모터의 전류를 측정하고,상기 측정된 모터의 전류를 필터링하고,상기 필터링된 모터의 전류 크기를 증폭시키고,상기 증폭된 모터의 전류 파형을 구형파 형태로 변환시키는 것을 더 포함하는 전자식 주차 브레이크 시스템의 제동력 제어방법.
- 제 1 항에 있어서,홀 센서 또는 엔코더를 이용하여 모터의 회전수를 검출하고,상기 검출된 모터의 회전수와 상기 추정된 모터의 회전수를 이용하여 상기 전자식 주차 브레이크 시스템의 고장을 판단할 때에, 상기 검출된 모터의 회전수와 상기 추정된 모터의 회전수를 비교하여 두 차이가 미리 정해진 기준 값 이상이면, 상기 전자식 주차 브레이크 시스템에 고장이 발생한 것으로 판단하는 전자식 주차 브레이크 시스템의 제동력 제어방법.
