Abstract

본 발명은 자동차의 실내공기질 센싱 및 제어장치에 관한 것으로서, 공기질 관련 센서들을 연결하여 센서데이터를 얻고, 얻은 데이터를 신호처리한 후 주 제어기에서 실행해야 할 명령을 차량 통신을 통하여 주 제어기에 전송하는 센서 및 제어 모듈로 구성되는 것을 특징으로 한다.

Description

자동차의 실내공기질 센싱 및 제어장치
본 발명은 자동차의 실내공기질 센싱 및 제어장치에 관한 것으로서, 보다 상세하게는 차량 실내 공기 오염 감지 및 오염 제거를 위한 통합 센서 모듈 및 공기질을 최적화하는 제어 모듈로 구성된 자동차의 실내공기질 센싱 및 제어장치에 관한 것이다.
일반적으로 기존의 차량은 차 실내의 공기질을 감지하기 위해 주 제어기(차량 내부에 장착되어 운전자에 의해 조절)에 센서가 직접적으로 연결되어 센서신호에 연동되게 제어기가 동작하거나 아니면 센서가 존재하지 않는다. 이와 같은 센서연결 방식은 현재 많은 공기질 감시 센서들이 결합되어야 하는 상황에서 장착시 제어기와 센서 사이의 거리 및 제어기 프로세서들의 커다란 성능향상을 요구하는 등 문제를 일으키고 있다.
도 1은 기존 차량 시스템에서의 공기질 제어를 위한 장치 구성도의 일 예를 나타낸다.
도시한 바와 같이, 일산화탄소 및 이산화탄소를 감지하여 차량에 붙어 있는 공조제어기에 센서 신호가 바로 입력된다. 이와 같은 특성에 의해 기존 공기질 센서 모듈 및 제어시스템은 기존의 차량 공조 제어시스템에 단지 센서가 1개 또는 2개 추가되어 단순한 센서정보를 제공하는 수준이었으며, 현재 대두되고 있는 많은 발암 물질등의 감지 및 제거를 위한 독립적 기능을 수행할 수 없었다.
본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 현재 문제시되고 있는 차 실내의 발암 물질 및 기타 유해 물질을 감지하는 센서들을 주 제어기의 큰 변화를 발생시키지 않고 수행할 수 있는 통합센서모듈을 제공하는 것으로, 공기질 관련 센서들을 연결하여 센서데이터를 얻고, 얻은 데이터를 신호처리 후 주 제어기에서 실행해야 할 명령을 차량 통신을 통하여 주 제어기에 전송하는 센서 및 제어 모듈로 구성된 장치를 제공하는데 있다.
전술한 목적을 달성하기 위해, 본 발명에 따른 자동차의 실내공기질 센싱 및 제어장치는, 공기질 관련 센서들을 연결하여 센서데이터를 얻고, 얻은 데이터를 신호처리한 후 주 제어기에서 실행해야 할 명령을 차량 통신을 통하여 주 제어기에 전송하는 센서 및 제어 모듈로 구성된다.
전술한 바와 같은 구성의 본 발명에 따르면, 공기질 관련 센서들을 연결하여 센서데이터를 얻고, 얻은 데이터를 신호처리한 후 주 제어기에서 실행해야 할 명령을 차량 통신을 통하여 주 제어기에 전송하는 센서 및 제어 모듈로 구성되어 있으므로, 현재 대두되고 있는 많은 발암 물질등의 감지 및 제거를 위한 독립적 기능을 수행할 수 있다는 이점이 있다.
도 1은 종래의 자동차의 실내 공기질 센서 모듈 및 제어 시스템 구성을 나타내는 블록도.
도 2는 본 발명에 따른 자동차용 차실내 공기질 통합 센서 모듈 및 제어 시스템 구성을 나타내는 블록도.
도 3은 본 발명에 따른 통합센서 모듈 및 제어 시스템의 신호 처리 구성을 나타내는 순서도.
이하, 첨부된 도 2와 도 3을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.
도 2는 본 발명에 따라 고안된 공기질 통합 센서 모듈 및 제어모듈을 포함하는 시스템 장치 구성도이다. 기존 시스템과의 차이점은 먼저 기존 주 제어기와 단독으로 결합되던 센서들이 독립적 모듈을 형성하여 신호 처리되고 주 제어기와 차량통신을 통해 결합되며 차량통신을 통해 주 제어기에 제어 명령을 송부한다. 또한 결합된 센서는 기존 차량에 장착되지 않았던 CO2, CO, VOC(휘발성 유기 화합 물) 및 NOX(질소 산화물)을 감지할 수 있도록 센서들이 결합되었다.
따라서, 본 발명에 따른 구동 장치는 공기질 측정을 위한 센서들이 기본 시스템 보다 많아지고 센서에 대한 신호를 구동장치 내부에서 처리하는 것에 대응하는 신호처리를 수행한다.
도 3은 본 발명에 따라 신호 처리부에서 수행하는 처리내용을 보여준다.
도시한 바와 같이, 센서신호가 센서부에서 신호처리부로 A/D(아날로그에서 디지털로 변환)변환을 통해 신호처리부에 저장된다.
저장된 신호는 신호의 특성에 따라 신호처리 필터링을 수행한다.
필터링이 수행된 신호 데이터는 에러에 대한 보정을 수행한다.
보정이 수행된 신호는 기존에 구성된 데이터 베이스 및 실시간 입력 정보를 바탕으로 하여 현재의 공기질 상태를 결정한다. 공기질 상태의 결정과 함께 각 공기질 상태에 대한 제어 명령 발생 및 Fail/Safety 기능이 수행된다.
이와 같은 과정이 수행된 후 차량 통신을 이용하여 차량의 공조제어 시스템에 대해 제어 명령을 전송한다. 이와 같은 명령에 기반하여 차량 공조 제어시스템이 명령에 따라 작동한다.
또한 시스템의 특성에 따라 제어 명령을 공조시스템에 전송한 후 일정 시간 안에 전송된 제어명령에 대한 처리 결과 응답을 차량 공조제어 장치로부터 받을 수 있으며, 이렇게 받은 데이터를 이용하여, 현재 측정된 공기질 제어 명령을 발생시키기 위한 고려 조건으로 적용할 수 있다.
