본 고안은 차량의 냉각수온센서에 관한 것으로, 보다 상세하게는 차량엔진의 냉각수 온도를 조절하는 서머스탯에 장착된 냉각수온센서가 부식등 에 의해 이상상태가 발생하였을 경우 이를 감지하는 시스템에 관한 것이다.The present invention relates to a cooling water temperature sensor of a vehicle, and more particularly, to a system for detecting a cooling water temperature sensor mounted on a thermostat controlling a cooling water temperature of a vehicle engine when an abnormal condition occurs due to corrosion or the like. .

일반적으로 차량엔진에는 엔진구동에 의해 실린더 등에 발생된 열을 감소시키는 냉각수의 온도를 적절하게 조절하기 위하여 서머스탯(thermostat)이 장착되어 있다.In general, a vehicle engine is equipped with a thermostat to appropriately control the temperature of the coolant, which reduces heat generated in a cylinder or the like by driving the engine.

상기 서머스탯은 냉각수의 온도를 감지하는 냉각수온센서가 내부에 설치되어, 냉각수가 항상 일정한 온도를 유지하도록 하기위하여 냉각수온센서가 냉각수의 온도를 감지하여 컴퓨터부(ECU)에 인가하면 컴퓨터에서는 이를 비교판단하여 서머스탯을 개폐동작시켜 냉각수를 조절하였다.The thermostat is installed inside the cooling water temperature sensor that detects the temperature of the cooling water, so that the cooling water temperature sensor detects the temperature of the cooling water and applies it to the computer unit (ECU) in order to maintain the constant temperature. Comparative judgment was made to control the cooling water by opening and closing the thermostat.

그런데 상기 냉각수온센서는 수분침투 등에 의해 부식되었을 경우 감지된 냉각수온도를 정확하게 컴퓨터부(ECU)에 전달하지 못하게 되어 컴퓨터부에서는 냉각수온센서로 부터 전달된 신호를 잘못판단하여 엔진이 갑자기 꺼지는 등의 엔진부조현상이 발생되는 문제점이 있었다.However, when the cooling water temperature sensor is corroded by moisture penetration, etc., the detected cooling water temperature cannot be accurately transmitted to the computer unit (ECU), and the computer unit incorrectly judges the signal transmitted from the cooling water temperature sensor and suddenly turns off the engine. There was a problem that the engine relief phenomenon occurs.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 본 고안의 목적은 서머스탯에 설치된 냉각수온센서가 부식 등에 의해 고장발생되었을 경우 이를 즉시 잠지하여 외부에 알릴 수 있는 장치를 제공하는데 있다.The present invention is devised to solve the above problems, an object of the present invention is to provide a device that can immediately notify the outside by locking it when the cooling water temperature sensor installed in the thermostat failure caused by corrosion.

상기 목적을 달성하기 위하여 본 고안은 서머스탯에 설치되어 냉각수의 온도를 감지하여 컴퓨터부(ECU)에 전달하는 냉각수온센서와, 상기 냉각수온센서로 부터 인가된 신호값을 설정된 설정신호값과 비교연산하여 냉각수온센서의 상태를 판단하는 컴퓨터부와, 상기 컴퓨터부로 부터 이상상태의 신호가 인가되었을 경우 온(ON) 절환되어 외부에 경고하는 경고표시부로 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention is installed in the thermostat and detects the temperature of the cooling water and transmits it to the computer unit (ECU), and compares the signal value applied from the cooling water temperature sensor with a set signal value. Computing computer unit for determining the state of the coolant temperature sensor, and when the abnormal state signal is applied from the computer unit is ON (ON) is characterized in that it consists of a warning display unit for warning to the outside.

이하 첨부된 도면을 참조하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제 1 도를 참조하여 설명하면, 차량의 엔진(도시안됨)을 냉각시키는 냉각수의 온도를 조절하는 서머스탯(10)에 설치되어 냉각수의 온도를 감지하는 냉각수온센서(20)를 컴퓨터부(ECU)(30)에 접속연결시키고,상기 컴퓨터부(30)에는 컴퓨터부로 부터 경고신호가 인가되었을때 온(ON) 절환되어 점등되는 경고등(50)을 접속연결시킨다.Referring to FIG. 1, the cooling unit temperature sensor 20 installed in the thermostat 10 for adjusting the temperature of the cooling water for cooling the engine of the vehicle (not shown) detects the temperature of the cooling water. (30), the computer unit 30 is connected to the warning light 50 that is switched ON when the warning signal is applied from the computer unit (ON).

상기 컴퓨터부(30)에는 냉각수온센서(20)로 부터 정상동작할때에 인가 되어야할 신호를 설정된 냉각수온값으로 하여 저장시킨후 냉각수온센서(20)로 부터 인가되는 냉각수온값과 비교연산하여 일치하지 않을 경우 경고등(50)을 점등시키게 된다.The computer unit 30 stores the signal to be applied during the normal operation from the cooling water temperature sensor 20 as the set cooling water temperature value, and compares and compares the cooling water temperature with the cooling water temperature value applied from the cooling water temperature sensor 20. If not, it turns on the warning light (50).

즉 냉각수온센서(20)로 부터 컴퓨터부(30)에 인가되는 냉각수온값은 항상 일정하게 점진적으로 상승해야 정상인데, 냉각수온센서(20)가 부식 등에 의해 고장발생하게 되면 감지된 냉각수온값이 불규칙적으로 상승하게 되므로 컴퓨터부(30)에서 이를 설정된 냉각수온값과 비교하여 냉각수온센서(20)가 고장상태임을 판단하여 경고등(50)을 온(ON)절환시킨다.That is, the cooling water temperature value applied from the cooling water temperature sensor 20 to the computer unit 30 should always gradually increase gradually. If the cooling water temperature sensor 20 malfunctions due to corrosion or the like, the detected cooling water temperature value is irregular. Since it rises to the computer unit 30 compares it with the set cooling water temperature value, and determines that the cooling water temperature sensor 20 is in a failure state to switch the warning lamp 50 ON.

따라서 운전자는 경고등(50)이 점등되면 냉각수온센서(20)가 비정상상태임을 인지하여 즉시 조치를 취할 수 있게 되므로 안전운행을 할 수 있게 된다.Therefore, the driver recognizes that the coolant temperature sensor 20 is in an abnormal state when the warning lamp 50 is turned on, and thus can take immediate action.

이상 설명에서 알 수 있는 바와같이 분 고안은 차량의 엔진과열을 방지하기 위하여 설치된 냉각수의 온도를 조절하는 서머스탯에 냉각수의 온도를 감지하는 냉각수온센서를 장착하고 상기 냉각수온센서가 수분등의 참투에 의해 부식되어 정상동작을 하지 못할 경우 컴퓨터부(ECU)에서 즉시 감지하여 비정상 상태임이 판단되면 경고 등을 점등시켜 외부에 신속하게 알리므로서 안전운행을 할 수 있게 된다.As can be seen from the above description, the invention is equipped with a cooling water temperature sensor for sensing the temperature of the cooling water in the thermostat for controlling the temperature of the cooling water installed to prevent the engine overheating of the vehicle, and the cooling water temperature sensor is confronted with moisture. If it is corroded and cannot operate normally, it is detected by the computer unit (ECU) immediately and if it is determined that the abnormal state is turned on, a warning light is turned on to promptly inform the outside and to operate safely.
