It relates to a device for detecting an abnormal state of a cooling fan of a vehicle.

종래 차량의 냉각팬 제어장치에 있어서는 입출력 제어부를 통해 냉각수 온도등의 데이터를 입력받는데 만일 냉각수 온도가 상승하면 CPU의 제어에 의해 입출력 제어부로부터 냉각수 온도의 상승을 계기판에 표시해 준다.In a conventional cooling fan control device, data such as coolant temperature is input through an input / output control unit. If the coolant temperature rises, the controller displays a rise in the coolant temperature from the input / output control unit under the control of the CPU.

따라서, 종래 차량에 있어서는 단지 냉각수온의 상승을 감지하여 계기판에 표시해 줄수 있었을 뿐 냉각팬 자체의 결함은 감지할 수 없어 이러한 냉각팬의 경함으로 인한 냉각성능의 저하를 가져왔고, 이로 인해 엔진과열 또는 차량의 주행자체가 불가능하게 되는 문제점가 있었다.Therefore, in the conventional vehicle, only the rise of the coolant temperature could be detected and displayed on the instrument panel, but defects of the cooling fan itself could not be detected, resulting in a decrease in the cooling performance due to the hardening of the cooling fan. There was a problem that the running of the vehicle itself is impossible.

이에 본 발명은 이와같은 종래의 문제점을 해결하기위하여 안출한 것으로 냉각팬 자체의 결함을 감지하여 이를 운전자에게 자동적으로 경고하여 줄 수 있도록 한 차량의 냉각팬 이상상태 감지장치를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a cooling fan abnormal state detecting device for a vehicle that detects a defect of the cooling fan itself and automatically warns a driver of the cooling fan itself. .

이와같은 목적을 달성하기 위한 본 발명은 데이터를 기록하고 읽기 위한 롬과, 데이터를 기록하고 읽을 수 있으며 또한 데이터를 지울 수 있는 램과, 상기 롬과 램에 접속되고, 냉각수 온도를 감지하여 냉각팬 온 조건에서 냉각팬을 제어하는 단계, 냉각팬 이상여부를 일차적으로 감지하는 단계, 일정온도 이후 임의로 냉각팬 오프후 온 제어로 팬 이상여부를 이차적으로 감지하는 단계, 경보음을 발생시키고 에어콘을 오프시켜 냉각수 온도를 상승시키는 요인을 제거하는 단계를 차례로 수행 하는 프로그램이 내장된 CPU와, 냉각수 온도데이타와 전압 데이터를 입력받아 상기 CPU에 전달하고, CPU의 제어에 의한 냉각팬 온/오프 제어신호와 에어콘 온/오프 제어신호 및 경고신호를 출력시키는 입출력제어부를 포함하여 구성한 것을 특징으로 한다.In order to achieve the above object, the present invention provides a ROM for recording and reading data, a RAM capable of recording and reading data, and erasing data, and a ROM connected to the ROM and RAM and sensing a coolant temperature. Controlling the cooling fan in the on condition, detecting the abnormality of the cooling fan primarily, turning off the cooling fan arbitrarily after a predetermined temperature, and detecting the abnormality of the fan by the on control, generating an alarm sound and turning off the air conditioner. A CPU having a built-in program that sequentially removes the factors that increase the coolant temperature, receives coolant temperature data and voltage data, and transmits the received coolant temperature data and voltage data to the CPU. And an input / output control unit for outputting an air conditioner on / off control signal and a warning signal.

이하, 본 발명 차량의 냉각팬 이상상태 감지장치의 실시예를 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings an embodiment of a cooling fan abnormal state detection device of the present invention will be described in detail.

제1도는 본 발명의 블럭도로 데이터를 기록하고 읽기 위한 롬(1)과, 데이터를 기록하고 읽을수 있으며 또한 데이터를 지울 수 있는 램(2)과, 상기 롬(1)과 램(2)에 접속되어 이들을 제어하기 위한 CPU(3)와 냉각수 온도데이타와 전압 데이터등을 입력받아 상기 CPU(3)에 전달하고, 그 CPU(3)의 제어에 의한 냉각팬 온/오프 제어신호와 에어콘 온/오프 제어신호 및 경고신호등을 출력시키는 입출력제어부(4)를 포함하는 하나의 엔진 제어모듈(5)로 구성된다.1 is a block diagram of the present invention, a ROM 1 for recording and reading data, a RAM 2 capable of recording and reading data and erasing the data, and a connection between the ROM 1 and the RAM 2; CPU 3 for controlling them, cooling water temperature data, voltage data, and the like are inputted to the CPU 3, and cooling fan on / off control signals and air conditioner on / off by the CPU 3 control. It consists of one engine control module 5 including an input / output control unit 4 for outputting control signals and warning signals.

그리고 상기 입출력 제어부(4)의 입력단으로는 냉각수 온도감지센서, 대기온도 감지 센서,트로틀 센서, 밧데리 전압, 차량 속도 센서,RPM센서, A/C온 스위치, 헤드램프 온/오프 스위치로부너의 데이터가 입력되고, 상기 입출력 제어부(4)의 출력단으로는 냉각팬 온/오프 제어신호, 인젝트 제어신호, 아이들 에어 제어 모터신호, 스파크 타이밍 제어신호, 에어콘 온/오프 제어신호, 헤드램프 제어신호 , 위험 램프 제어신호 , 충전장치 이상경고 램프 제어신호 , 주 전원 제어신호 , 제 충전 램프제어신호가 출력된다.In addition, the input of the input / output controller 4 includes a coolant temperature sensor, an air temperature sensor, a throttle sensor, a battery voltage, a vehicle speed sensor, an RPM sensor, an A / C on switch, a headlamp on / off switch and The input terminal of the input / output control unit 4 is a cooling fan on / off control signal, inject control signal, idle air control motor signal, spark timing control signal, air conditioner on / off control signal, head lamp control signal, Danger lamp control signal, charging device abnormality warning lamp control signal, main power supply control signal, charging lamp control signal are output.

한편, 이와같이 구성으로 이루어진 본 발명의 동작을 살펴보면 다음과 같다.On the other hand, look at the operation of the present invention made of the configuration as follows.

먼저, 입출력 제어부(4)를통하여 냉각수 온도 데이터, 전압데이타등을 입력받아 이를 CPU(3)에 전달하는데 이때의 냉각수 온도는 제 3도의 (a)와 같은 타이밍 차트로 나타난다.First, the coolant temperature data, the voltage data, etc. are received through the input / output controller 4 and transferred to the CPU 3, and the coolant temperature at this time is represented by a timing chart as shown in FIG.

또한 냉각팬 온시에는 냉각팬에 CPU(3)의 제어에 의해 입출력제어부(4)를 통하여 냉각팬 온 제어 신호가 출력되며, 이때의 냉각팬 온 제어신호는 제3도의 (b)와 같은 타이밍 챠트를 나타낸다.When the cooling fan is on, the cooling fan on control signal is outputted to the cooling fan through the input / output controller 4 under the control of the CPU 3, and the cooling fan on control signal at this time is the timing chart as shown in FIG. Indicates.

여기서, 냉각팬 온시에는 냉각팬 용량에 따라 5A-10A의 전류가 필요하므로 제3도의 C와 같이 전압의 저하가 발생하게 되는데 입출력 제어부(4)를 통하여 이러한 전압 저하의 데이터를 입력받은 CPU(3)에서는 냉각팬의 이상여부를 감지하게 된다.In this case, when the cooling fan is turned on, a current of 5A-10A is required according to the cooling fan capacity, and thus a voltage drop occurs as shown in C of FIG. 3. ) Detects an abnormality of the cooling fan.

이렇게 1차적으로 냉각팬의 이상여부를 감지후 계속 온도 상승시 CPU(3)에서는 임의로 냉각팬을 제어하여 2차적으로 냉각팬의 이상여부를 확인하여 만일 냉각팬 이상이 감지되었을 경우 냉각수 온도의 상승요인인 에어콘을 오프시킴과 아룰러 엔진 경고 램프를 통하여 경고하여 주는 것이다.In this way, if the temperature rises first after detecting the abnormality of the cooling fan, the CPU 3 arbitrarily controls the cooling fan and secondly checks whether the cooling fan is abnormal. The factor is to turn off the air conditioner and warn through the Allure engine warning lamp.

따라서, 엔진경고 램프를 통하여 냉각팬의 이상상태를 파악한 운전자는 냉각팬의 수리등 필요한 조치를 취할 수 있게 되는 것이다.Therefore, the driver who grasps the abnormal state of the cooling fan through the engine warning lamp can take necessary measures such as repair of the cooling fan.

이상에서 설명한 바와같은 본 발명은 종래와 같이 냉각수온의 상승을 감지하여 계기판에 표시해줌은 물론 차량의 냉각팬 자체의 결함까지도 감지하여 자동적으로 이상상태를 경고해 줌으로써 엔진의 냉각성분 저하로 인한 엔진과열 또는 차량의 주행자체가 불가하게 됨을 미연에 방지하고 냉각팬의 이상상태를 감지하여 이를 적기에 수리할 수 있는 효과가 있다.As described above, the present invention detects an increase in the cooling water temperature and displays an indicator on the instrument panel as well as detects a defect of the cooling fan itself of the vehicle and automatically warns of an abnormal state, thereby causing the engine to be deteriorated. It is possible to prevent overheating or the vehicle itself from being impossible, and to detect an abnormal state of the cooling fan and repair it in a timely manner.
