Abstract
전자 제어 장치를 구비한 엔진 제어 시스템의 제어를 위한 크랭크 각 위치 센서 신호 검출 방벙에 있어서, 전원 투입후 첫번째 신호 발생의 경우의 시간을 저장하는 단계; 적어도 두번째 이상의 발생된 센서 신호 발생 시간과 저장된 신호 발생 시간을 비교하는 단계; 비교된 값이 정상 신호 주기 보다 짧으면 상기 저장된 시간을 현재의 신호 발생시간으로 대치하고 그 다음신호 발생시간을 취하여 상기 대치된 시간과 비교하여 정상 신호주기와 근접할때 상기 대치 저장된 시간에 발생된 신호를 크랭크 각 위치 센서 신호로 인지하는 단계로 이루어진 것을 특징으로 하는 크랭크 각 위치 센서 신호 검출방법.CLAIMS 1. A method for detecting a crank angle sensor signal for controlling an engine control system having an electronic control device, the method comprising: storing a time in the case of a first signal generation after power-up; Comparing at least a second generated sensor signal generation time with a stored signal generation time; If the compared value is shorter than the normal signal period, the stored time is replaced with the current signal generation time and the next signal generation time is taken and compared with the replaced time to generate a signal generated at the replaced stored time when it is close to the normal signal period. Recognizing a crank angle position sensor signal, characterized in that consisting of a crank angle position sensor signal.
