Abstract

본 발명은 차량의 진단부위의 각 센서출력데이타를 병렬로 입력받아 설정레벨과 비교하여 차량상태를 진단토록 한 장치 및 방법으로, 병렬로 센서출력데이타를 제공받아 비교함으로써 수 마이크론초(㎲)의 에러도 즉시 감지할 수 있어 정밀진단을 가능케 한다.The present invention is a device and method for receiving the sensor output data of the diagnostic portion of the vehicle in parallel and comparing the set level with the set level, so as to diagnose the state of the vehicle, and to receive and compare the sensor output data in parallel for several micron seconds. Errors can also be detected immediately, enabling precise diagnosis.
