Claims (3)

  1. 엔진의 회전수를 나타내는 제1데이터 및 엔진부하를 나타내는 제2데이터를 파라미터로 사용하여 맵을 주사함으로써 엔진의 점화시기 및 연료공급중 최소한 하나를 제어하는 엔진제어장치에 있어서, 필터수단이 상기 제2데이터의 변화율을 억제하여 제3데이터를 제공하며, 엔진이 운전상태의 소정범위에 있을 때에만 제2데이터 대신에 제3데이터를 사용하여 맵을 주사하는 것을 특징으로 하는 엔진제어장치.
  2. 제1항에 있어서, 상기 소정범위가 스로틀밸브의 조작변수의 변화율, 엔진의 회전수 및 엔진 부하의 변화율이 모두 운전상태의 소정범위의 각 소정치 이하인 것을 특징으로 하는 엔진제어장치.
  3. 제1항에 있어서, 상기 필터수단이 제어장치에 주기적으로 입력되는 제2데이터의 전류치 및 전류치가 입력되기 전에 1사이클당 제어장치에 입력된 제2데이터치의 가중평균을 소정비에 의하여 연산함으로써 제3데이터를 제공하기 위한 프로세서로 이루어지는 것을 특징으로 하는 엔진제어장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
