- 센서로부터 수신되는 아날로그 형태의 입력 신호를 수신하여 상기 입력 신호를 순차적으로 전송하여 상기 입력 신호로 자동차를 총괄 제어하는 다수의 마이컴과,상기 다수의 마이컴의 입력 포트 각각에 설치되어 상기 입력 신호를 디지털 형태로 변환하는 디지털 변환기를 포함하되,상기 센서로부터 공급되는 입력 신호의 크기를 기 설정된 게인(b)과 기 설정된 오프셋 전압(a)으로 강하한 후 다음 마이컴으로 전송하는 버퍼;상기 다수의 마이컴 각각의 그라운드 포트 사이에 연결되어 이전 마이컴의 오프 셋 전압(Vr1)을 다음 마이컴으로 전송하는 오프 셋 전압 전송부를 포함하고,상기 다음 마이컴은,상기 버퍼를 통해 크기가 강하된 입력 신호(Vo), 상기 이전 마이컴의 오프셋 전압(Vr1)과 다음 마이컴의 오프 셋 전압(Vr2)의 차, 상기 버퍼의 게인(b) 및 오프셋 전압(a)은 근거로 보정하여 상기 센서의 입력 신호(Vi)를 복원하도록 구비되는 것을 특징으로 하는 자동차의 입력 신호 수신 장치.
- 제1항에 있어서, 상기 버퍼의 출력 신호(Vo)의 크기는, 센서(11)의 입력신호(Vi)와 기 설정된 버퍼의 게인(b)의 곱과 기 설정된 버퍼의 오프 셋 전압(a)의 합으로 결정되는 것을 특징으로 하는 자동차의 입력 신호 수신 장치.
- 제2항에 있어서, 상기 센서의 입력 신호(Vi)는, 버퍼의 출력 신호(Vo)와 상기 버퍼(31)의 오프 셋 전압(a)의 차 및 상기 버퍼(31)의 게인(b)의 비와 상기 이전 마이컴(M1)의 오프 셋 전압(Vr1)과 다음 아미컴(M2)의 오프 셋 전압(Vr2)의 차로 결정되는 것을 특징으로 하는 자동차의 입력 신호 수신 장치.
