Abstract

본 발명은 산소 센서의 활성화 판단 장치 및 그 방법에 관한 것으로서, 더욱 상세하게는, 차량의 배기관에 장착되어 배기가스의 산소량을 감지하는 산소 센서의 활성화 판단 장치 및 그 방법에 관한 것이다. 감지되는 전기적인 신호를 디지털 값을 변환하여 일대일 대응으로 받아들이고 디지털 값을 받아들인 값들과 비교하여 최대값인가 최대값인가를 판단하고 최대값과 최소값의 차를 계산하여 기준값과 비교하여 산소센서의 활성화를 판단한다. 따라서 본 발명에 따른 산소센서의 활성화 판단 장치 및 그 방법에서는 데이터를 입력하여 활성화 판단 기준선을 설정하는 단계를 제거하고 직접 산소센서의 신호선에 해당하는 값을 읽어들여 최대값과 최저값과의 차이를 계산하여 기준값과 비교하여 산소센서의 활성화를 판단할 수 있는 효과가 있다.The present invention relates to an apparatus for determining an activation of an oxygen sensor and a method thereof, and more particularly, to an apparatus for determining an activation of an oxygen sensor mounted on an exhaust pipe of a vehicle and detecting an oxygen amount of exhaust gas. Activates the oxygen sensor by converting the digital signal to one-to-one correspondence by converting the digital value and comparing the digital value with the received value to determine whether it is the maximum value or the maximum value Judge. Therefore, the apparatus and method for determining the activation of an oxygen sensor according to the present invention eliminates the step of setting the activation determination reference line by inputting data and directly calculates the difference between the maximum value and the minimum value by reading a value corresponding to the signal line of the oxygen sensor. By comparing with the reference value there is an effect that can determine the activation of the oxygen sensor.
