Abstract
본 발명은 자동차의 냉각장치에 관한 것으로, 특히, 냉각수 순환경로상의 소정의 위치에 설치되어, 냉각수의 압력을 검출하는 수압센서(10)와; 냉각수 순환경로상의 소정의 위치에 설치되어, 냉각수의 온도를 검출하는 수온센서(20)와; 차량정보표시판넬 내에 설치되며, 소정의 제어신호에 의해 동작되어, 엔진의 과열여부를 운전자에게 알리는 표시/경보장치(40)와; 상기 수압센서(10)와 수온센서(20)의 신호 출력단과 표시/경보장치 사이에 접속되어, 상기 수압센서(10)에서 인가되는 냉각수의 압력과, 상기 수온센서(20)에서 인가되는 냉각수의 온도를 검출하여, 사용자에 의해 기입력된 냉각수의 압력과, 냉각수의 온도와, 엔진의 온도 사이의 관계를 나타낸 데이타 테이블(DATA TABLE)과 비교 판단하므로써 엔진의 과열여부를 조기판단하고, 엔진이 과열되는 중인것으로 판단될 경우에는, 상기 표시/경보장치(40)를 동작시키라는 소정의 제어신호를 출력하는 마이컴(30)을 포함하여 구성됨을 특징으로 하는 자동차의 엔진 과열 경고장치와, 수압센서(10)와 수온센서(20)를 이용하여 냉각수의 수압과 수온을 검출하는 냉각수상태 검출단계(100)와; 상기 냉각수상태 검출단계(100)를 수행한 후, 상기 냉각수상태 검출단계(100)에서 검출한 냉각수의 온도와 압력을, 사용자에 의해 마이컴(30)에 기 입력된 냉각수의 압력과, 냉각수의 온도와, 엔진의 온도 사이의 관계를 나타내는 데이타 테이블(DATA TABLE)과 비교 판단하므로써 엔진의 과열여부를 조기 검출하는 엔진과열여부 판단단계(200)와; 상기 엔진과 열여부 판단단계(200)를 수행한 결과, 엔진이 과열중에 있는 것으로 판단됨에 따라, 상기 표시/경보장치(40)를 동작시켜 엔진이 과열중에 있음을 나타내는 표시단계(300)를 포함하여 구성됨을 특징으로 하는 자동차의 엔진 과열 경고장치의 제어방법이다.The present invention relates to a cooling apparatus for an automobile, and in particular, a water pressure sensor (10) which is installed at a predetermined position on a cooling water circulation path and detects the pressure of the cooling water; A water temperature sensor 20 installed at a predetermined position on the cooling water circulation path and detecting a temperature of the cooling water; A display / alarm device 40 installed in the vehicle information display panel and operated by a predetermined control signal to inform the driver whether the engine is overheated; Connected between the signal output terminal of the water pressure sensor 10 and the water temperature sensor 20 and the display / alarm device, the pressure of the coolant applied from the water pressure sensor 10 and the coolant applied from the water temperature sensor 20. By detecting the temperature and comparing it with a data table showing the relationship between the pressure of the coolant, the temperature of the coolant, and the temperature of the engine, the engine is overheated. If it is determined that it is being overheated, the engine overheat warning device of the vehicle, characterized in that it comprises a microcomputer 30 for outputting a predetermined control signal to operate the display / alarm device 40, the water pressure sensor Cooling water state detection step 100 for detecting the water pressure and the water temperature of the cooling water by using the 10 and the water temperature sensor 20; After the coolant state detection step 100 is performed, the temperature and pressure of the coolant detected in the coolant state detection step 100 are input to the microcomputer 30 by the user, and the temperature of the coolant. An engine overheating determination step (200) of detecting whether the engine is overheated early by comparing and judging with a data table indicating a relationship between engine temperatures; As a result of performing the engine and heat determination step 200, as it is determined that the engine is in overheating, the display / alarm device 40 is operated to include a display step 300 indicating that the engine is in overheating. It is a control method of the engine overheat warning device of a vehicle, characterized in that configured.
