Abstract
본 발명에 따라 배기 가스 센서의, 온도와 무관한 출력 신호가 발생되고, 측정된 센서 전압 및 측정 셀의 센서 내부 저항을 이용해 제1 단계에서 측정 셀의, 전기 회로 없이 조정될 수 있을 네른스트 전압이 계산되고, 제2 단계에서 제1 단계에서 도출되는 네른스트 전압이 명목 온도에서의 네른스트 전압으로 환산되고, 명목 온도에 대한 측정 셀의 온도의 편차가 작으면, 직접 명목 온도에서의 네른스트 전압이 결정된다.
또한, 본 발명은 상기 방법의 실행에 상응하는 장치에 관한 것이다.
상기 방법 및 이 방법을 실행하기 위한 장치를 이용해 배기 가스 센서의 온도와 무관한 출력 신호가 명목 온도와 측정 셀의 실제 세라믹 온도 사이에 편차가 발생하는 작동 단계들에서도 왜곡없이 제공되는 것이 달성된다. 이를 통해 배기 가스 센서로서 람다 센서와 관련하여 더 정확한 람다 제어가 가능해질 수 있다. 그 결과, 람다 제어의 스위칭온 조건들은 덜 제한적으로 설계될 수 있다. 그러므로 람다 제어가 더 빈번하게 활성화될 수 있으며, 이는 연료 소비와 유해 물질 배출을 줄이는데 도움이 된다.
