Title: 자동자휴즈(릴레이)단선진단및위치표시장치의카트리지형정션박스
Filed: 1999-06-25
Abstract: 본 고안은 자동차의 휴즈박스 또는 정션박스의 단선 부품 검사장치에 관한 것으로서, 기존에 설치되어있는 휴즈박스나 정션박스를 개조하지 않고도 간단히 장착할 수 있도록 고안된 휴즈 및 릴레이의 단선 진단 및 위치 표시장치에 관한 것이다. 
     본 고안은 탈, 부착이 용이하게 고안된 카트리지 형태의 단선 진단 및 단선위치 표시 장치로서, 휴즈 및 릴레이 등의 전기부품의 단선과 같은 이상 발생시 간단히 그 단선 위치를 알아볼 수 있도록 하는 전자회로를 내장한 카트리지형 진단장치를 기존의 휴즈박스(21) 또는 정션박스(18)의 윗면 또는 밑면에 간단히 덮어 씌워 그 기능을 수행하도록 하는 것을 목적으로 개발한 카트리지형 단선 진단 및 위치 표시장치이다. 
     더욱 상세하게는 도1의 예와 같이 휴즈(14)가 기존의 조립위치인 기존 정션박스(18)의 커넥터(13)에 꽂혀서 그 기능을 발휘하게 되지만 이때 진단회로기판을 삽입하기 위해 도1의 기존 정션박스의 내부 판넬(17)의 안쪽이나 기존 휴즈박스(21)의 내부 여유 공간을 이용하여 전자회로 기판(12)을 분리 삽입해야 하는 난해한 작업을 해야만 했었다. 이러한 기능들, 다시말하면 휴즈의 단선 발생시 그 발생사실과 발생 위치를 각종 신호로서 알려주는 기능을 카트리지형 진단장치에 내장시켜 그 케이스(11)를 도1, 도2, 도3에서 보는 바와 같이 조립할 수 있도록 기존 케이스(18, 21)의 커넥터(13) 간격과 동일하게 동수 만큼 구비한 커넥터(13, 16)을 전자회로 기판(12)에 일체로 고정한 진단장치(11)를 휴즈(14)의 삽입 위치에 그대로 조립하고, 카트리지 케이스(11)의 동일한 위치에 휴즈(14)를 삽설하면 그 연결 작업이 끝나게 된다. 다른 배선은 기존에 형성되어진 배선과 동일하게 사용되므로 그대로 둔다. 이렇게 되면, 휴즈(14)가 과부하 등의 원인으로 단선 되면 이를 진단회로기판(12)이 이를 감지하여 위치표시램프(15)를 점등하게 된다. 점등된 빛은 휴즈(14)의 투명한 부위를 통과하여 밝게 빛나게 되므로 운전자는 손쉽게 그 위치를 파악하고 보조 휴즈를 이용하여 교체하면 정비작업이 끝나게 된다. 만일 릴레이와 같은 불투명한 케이스의 부품인 경우에는 그 해당 부품의 근접 위치에 화살표 또는 삼각형 모양의 방향을 지시할 수 있는 표시 수단을 이용하여 해당 부품을 가리키도록 한다. 이러한 카트리지 형태의 진단장치는 도3에서 보는 바와 같이 그 조립방법을 다소 다르게 형성할 수도 있고, 그 조립 위치도 기존 케이스(18)의 윗면이나 기존 케이스(21)의 안쪽 밑면에 조립할 수도 있다. 
     이로써, 자동차 조립공정에서의 배선 연결작업에서는 물론이고, 이미 출고되어 운행중인 자동차에도 기존의 배선이나 케이스(18)의 변형이 없이도 쉽게 부착하는 방식으로 단선 진단 및 위치 표시기능을 가질 수 있고, A/S도 용이하게 하여 물적 자원의 절약은 물론이고, 시간과 비용의 절약에도 크게 기여하게 되었으며, 어떠한 차종이든지 그 단선 진단 및 위치표시 기능의 적용이 용이하도록 하는데 본 고안의 목적이 있다. 
     부연하자면, 휴즈(14) 또는 릴레이와 같은 부품의 단선 발생 상황을 간단히 검사할 수 있고 그 위치를 표시할 수 있는 전자회로 기판(12)을 정션박스(18)의 일측에 설치함에 있어서, 기존에는 휴즈박스(18)의 여유공간이나, 표면 일측에 추가로 부착하거나, 정션박스(18)의 내부를 개조하여 전자회로기판(12)을 끼워넣는 방식을 주로 사용하게 되는데, 그 개조작업과 부착작업에 상당한 비용이 소요되고, 기존에 만들어 놓았던 금형을 모두 수정해야 하는 어려운 작업을 해야만 했지만, 본 고안은 그러한 복잡한 개조작업을 거치지 않고도 간단히 정션박스(18) 또는 휴즈박스(18)의 위에 그대로 덮어씌워 장착하는 방식의 카트리지형 진단장치(11)를 제공하므로써 개조비용을 획기적으로 줄이고 복잡한 배선을 추가로 발생시키지 않으므로 해서 조립 작업성에 전혀 지장을 주지 않도록 고안한 것을 중요한 특징으로 한다.

Abstract: PURPOSE: A control method for an exhaust gas recirculation is provided to reduce nitric oxide in exhaust gas by enabling an EGR(exhaust gas recirculation system) to operate even at a lower temperature than the temperature of coolant. CONSTITUTION: An EGR control amount is calculated in an EGR control target map(10) and multiplied by a coolant temperature correcting coefficient. The coolant temperature correcting coefficient starts when coolant temperature is in about 30deg.C with the start of the EGR and slowly increases until the coolant temperature is in about 70deg.C. Then, the correcting coefficient becomes 1.0 in a maximum EGR operating temperature. The EGR control amount is output to an output mode(20) and an actual EGR control value is subtracted from the EGR control amount. The subtracted value is output to an EGR bent solenoid/EGR vacuum solenoid map(30) to obtain a diagram about the actual EGR value and the duty value of the EGR vent solenoid/EGR vacuum solenoid map. Herein, the EGR vent solenoid map controls an EGR vent solenoid valve in case of a negative actual EGR value and the EGR vacuum solenoid map controls an EGR vacuum solenoid valve in case of a positive actual EGR value. Therefore, even if the temperature of coolant is less than 70deg.C, the ERG operates so nitric oxide is reduced and air pollution is prevented.
