Abstract
Description
Claims (6)
- 자동차의 전방 범퍼(24)와 강성체의 충돌과, 상기 전방 범퍼(24)와 보행자 또는 동물의 충돌을 구별하기 위한 차량 충돌 감지 시스템(23)에 있어서,상기 자동차의 전방 범퍼(24)에 장착되는 피에조 필름 센서(28)와,상기 피에조 필름 센서(28)와 인접하여 상기 자동차의 전방 범퍼(24)에 장착되는 초자왜성 검지 요소(giant magnetostrictive sensing element; 32)와,자동차가 보행자 또는 동물과 충돌한 것인지 여부를 결정하기 위해, 상기 피에조 필름 센서(28) 및 상기 초자왜성 검지 요소(32)의 출력을 나타내는 신호를 분석 및 비교하기 위한 장치를 포함하는차량 충돌 감지 시스템.
- 제 1 항에 있어서,상기 초자왜성 검지 요소(32)는 테르페놀-D(Terfenol-D)형 검지 요소인차량 충돌 감지 시스템.
- 제 1 항 또는 제 2 항에 있어서,상기 신호의 분석 및 비교 장치는 (a) 상기 피에조 필름 센서(28)에 의해 생성되는 신호로부터 일정 주파수 또는 1,000Hz 이하의 주파수 범위에서 제 1 진폭을 결정하고, (b) 상기 초자왜성 검지 요소(32)에 의해 생성되는 신호로부터 일정 주 파수 또는 10,000Hz 이상의 주파수 범위에서 제 2 진폭을 결정하며, (c) 보행자나 동물과의 충돌이 발생한 것인지 여부를 결정하기 위해 상기 제 1 진폭과 상기 제 2 진폭을 비교하는차량 충돌 감지 시스템.
- 제 3 항에 있어서,상기 피에조 필름 센서(28)에 의해 생성되는 신호와 상기 초자왜성 검지 요소(32)에 의해 생성되는 신호의 비교는 상대적인 신호 세기의 비율을 결정하는 것과, 상기 피에조 필름 센서(28)에 의해 생성되는 신호를 적어도 2개의 진폭 기준과 비교하는 것과, 상기 초자왜성 검지 요소에 의해 생성되는 신호를 적어도 2개의 진폭 기준과 비교하는 것을 포함하는차량 충돌 감지 시스템.
- 제 1 항 또는 제 2 항에 있어서,상기 신호의 분석 및 비교 장치에 신호를 제공하는 가속도 센서를 더 포함하며, 상기 신호의 분석 및 비교 장치는 차량이 보행자나 동물과 충돌한 것인지 여부를 결정함에 있어서 상기 가속도 센서로부터의 신호를 이용하는차량 충돌 감지 시스템.
- 제 1 항 또는 제 2 항에 있어서,상기 신호의 분석 및 비교 장치에 의해 자동차가 보행자나 동물과 충돌한 것으로 결정된 경우, 상기 신호의 분석 및 비교 장치는 신호를 보내서 차량의 안전 장치(26)를 작동시키는차량 충돌 감지 시스템.
