이하, 본 고안인 엔진 초기 기동시 냉각수온 조절 장치의 작용을 도 2에 도시된 실시예에 기초하여 설명한다.Hereinafter, the operation of the coolant temperature control device at the initial start of the engine of the present invention will be described based on the embodiment shown in FIG. 2.
운전자가 점화스위치(IGN)를 조작하여 엔진을 시동하면 수온 센서(S)에 의하여 냉각수온이 감지되며, 이때는 엔진이 초기 기동상태이므로 낮은 냉각수온이 감지되어 마이컴(μ-com)에 입력된다.When the driver starts the engine by operating the ignition switch (IGN), the coolant temperature is sensed by the water temperature sensor S. At this time, since the engine is in an initial starting state, a low coolant temperature is detected and input to the microcomputer (μ-com).
이에, 상기 마이컴(μ-com)은 출력단에 접속된 트랜지스터(TR)에 신호 전류를 인가하지 않아 메인 릴레이(RLY1)는 평시 상태인 오픈상태를 유지한다.Accordingly, the microcomputer μ-com does not apply a signal current to the transistor TR connected to the output terminal, so that the main relay RLY1 maintains the normally open state.
엔진이 가열되어 상기 수온 센서(S)를 통해 냉각수온이 80℃ 전후로 상승되었음이 감지되어 입력되면 상기 마이컴마이컴(μ-com)은 출력단에 접속된 트랜지스터(TR)에 신호 전류를 인가하며, 이는 바이어스전압으로 작용하여 상기 트랜지스터(TR)는 도통상태에 놓인다.When the engine is heated and sensed that the coolant temperature has risen around 80 ° C through the water temperature sensor S, the microcomputer com (μ-com) applies a signal current to the transistor TR connected to the output terminal. The transistor TR is in a conductive state by acting as a bias voltage.
이에, 전원 공급에 따라 메인 릴레이(RLY1)의 여자코일 주위에 자장이 형성되어 상기 메인 릴레이(RLY1)는 평시 오픈상태에서 크로스상태로 변환된다.Accordingly, a magnetic field is formed around the excitation coil of the main relay RLY1 according to the power supply, so that the main relay RLY1 is changed from the normally open state to the cross state.
다음으로, 냉각 팬 릴레이(RLY2)가 연동되어 평시 오픈상태에서 크로스상태로 변환되며, 냉각 팬 모터(M)에 전원이 공급되어 상기 냉각 팬 모터(M)가 작동되고 연동되어 냉각 팬이 회전된다.Next, the cooling fan relay RLY2 is interlocked to change from the normally open state to the cross state, and power is supplied to the cooling fan motor M so that the cooling fan motor M is operated and interlocked to rotate the cooling fan. .
또한, 상기 메인 릴레이(RLY1)와 동기되는 복수개(N개)의 전장품(M1~MN)이 연동된다.In addition, a plurality of (N) electrical appliances M 1 to M N synchronized with the main relay RLY1 are interlocked.
상술한 바와 같이 본 고안인 엔진 초기 기동시 냉각수온 조절 장치는, 기계적인 서머스탯을 사용하지 않고 엔진 전자 제어 유니트 내의 마이컴을 통해 메인 릴레이를 제어하여 엔진 초기 기동시 냉각수온을 조절함으로써, 기계적인 서머스탯을 사용하지 않아 코스트를 저감시키고 회로의 안정성을 향상시키며, 메인 릴레이와 연동되는 다른 전장품이 부가적으로 제어되는 효과가 있다.As described above, the apparatus for controlling the coolant temperature at the initial start of the engine according to the present invention controls the main relay through a microcomputer in the engine electronic control unit without using a mechanical thermostat to adjust the coolant temperature at the initial start of the engine.
