Abstract

이 발명은 지정된 시간이 경과했는지를 판단하는 단계와, 워치 독 기능에 관련된 특정 메모리의 내용(숫자)을 클리어하는 단계와, 워치 독 기능에 관련된 특정 메모리의 내용(숫자)을 카운트 업하는 단계와, 워치 독 기능에 관련된 특정 메모리의 내용(숫자)을 특정 숫자와 비교 판단하는 단계와, 워치 독 기능 칩에 워치 독 펄스를 출력하는 단계로 이루어지는 것을 특징으로 하여 TCU가 정상동작하는지를 감시하다가 이상동작하면 즉시 리셋시킬 수 있는 TCU의 워치 독 기능 수행 방법에 관한 것이다.The present invention includes the steps of determining whether a specified time has elapsed, clearing the contents (number) of a specific memory related to the watchdog function, counting up the contents (number) of the specific memory related to the watchdog function, and And comparing and determining the contents (number) of a specific memory related to the watchdog function with a specific number and outputting a watchdog pulse to the watchdog function chip. The watchdog function of the TCU can be reset immediately.
