Abstract

PURPOSE: A preventing method of the starting of an engine is provided to prevent excessive operation of an engine when cooling water or lubricating oil such as engine oil is insufficient in a vehicle. CONSTITUTION: An engine control unit(100) examines if the amount of oil measured from an engine oil sensor(110) is under a reference value. If the measured value is not under the reference value, the engine control unit examines if the amount of the oil of a transmission measured from a transmission oil sensor(130) is under a reference value. If the measured value is under the reference value, the engine control unit generates an alarm message via an indication unit or generates an alarm sound via a speaker. And the engine control unit generates a disable signal to block the operation of an engine starting part(140). Thus, the engine is not started when cooling water or oil is not sufficient. And the engine control unit makes a user recognize the shortage of oil or cooling water via an input part, and examines if a cancellation key value for feeding an enable signal is input to the engine starting part. If the cancellation key value is input, the engine starting part is operated by generating an enable signal. Thereby, an operator recognizes the shortage of oil or cooling water, and moves a vehicle for supplementing cooling water or oil.

Description

냉각수/오일 량에 적응한 엔진의 시동방지 방법How to prevent starting of the engine adapted to the amount of coolant / oil

통상적으로, 차량의 정비가 불량하거나, 돌발적인 사고에 의해 차량에 손상이 있으면 냉각수나 엔진오일, 변속기(TM : "TRANSMISSION" 이하 "변속기"라 함) 오일 등이 유출될 수가 있다. 그런데 운전자가 이러한 점을 모르고 차량의 시동을 걸어 주행을 하게되면 엔진이 과열되어 사고의 원인이 될 수 있다. 그래서 기존에는 엔진오일이나 냉각수가 부족하면 차량의 표시부를 통해 이를 경보해주는 방법을 사용하여 왔다. 그러나 운전자가 표시부에 표시된 경보등을 감지하지 못할 경우에는 엔진에 무리가 가게되어 엔진의 내구성이 떨어지게 되는 문제점이 있다. 상기와 같은 문제가 심각할 경우에는 엔진이 과열되어 화재가 발생할 수도 있고 인명 사고를 초래할 수 있는 문제점이 있다.In general, when the vehicle is poorly maintained or damaged by an accident, the coolant, the engine oil, the transmission (TM) (hereinafter referred to as "transmission") oil, and the like may leak. However, if the driver does not know this and starts the vehicle, the engine may overheat and cause an accident. Therefore, in the past, if the engine oil or coolant is insufficient, the method of alarming through the display of the vehicle has been used. However, when the driver does not detect the alarm light displayed on the display unit, there is a problem in that the engine goes unreasonable and durability of the engine decreases. If the above problem is serious, there is a problem that the engine may be overheated and a fire may occur or cause a human accident.

따라서 본 발명의 목적은 냉각수나 오일이 부족한 상태에서 엔진을 보호하기 위한 방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a method for protecting an engine in a state in which coolant or oil is insufficient.

상기와 같은 목적을 달성하기 위하여 본 발명은 엔진오일 센서와 변속기오일 센서, 냉각수 오일 센서를 구비하고 있는 차량에서 엔진오일이나 변속기오일 또는 냉각수의 양 각각이 미리 정해진 량 이하이면 경보메시지를 발생하고, 엔진시동부가 동작하지 못하게 디스에이블 신호를 발생함을 특징으로 한다.In order to achieve the above object, the present invention generates an alarm message when the amount of engine oil, transmission oil, or coolant is less than a predetermined amount in a vehicle equipped with an engine oil sensor, a transmission oil sensor, and a coolant oil sensor. It is characterized in that the engine start unit generates a disable signal to prevent operation.

도 1은 본 발명의 실시예에 따른 오일이나 수량을 측정하여 엔진을 제어하기 위한 블록 구성도이다.1 is a block diagram for controlling the engine by measuring the oil or the amount according to an embodiment of the present invention.

엔진제어부(ECU : ENGINE CONTROL UNIT)(100)는 차량의 전반적인 동작을 제어하고 본 발명에 의해 냉각수나 오일의 측정 양에 따라 인에이블(ENABLE) 또는 디스에이블(DISABLE) 신호를 발생하여 엔진을 제어한다. 엔진오일 센서(110)는 엔진오일의 양을 측정하여 엔진제어부(100)로 전달한다. 냉각수 센서(120)는 차량의 과열을 방지하기 위한 냉각수의 양을 측정하여 엔진제어부(100)로 전달한다. 변속기오일 센서(130)는 변속기오일의 양을 측정하여 엔진제어부(100)로 전달한다. 엔진시동부(140)는 사용자가 차량의 시동키를 꽂아 시동을 걸면 엔진시동 신호를 발생하여 엔진(150)으로 전달한다. 상기 엔진시동부(140)는 엔진제어부(100)의 제어를 받아 동작하거나 동작하지 않는다. 일반적으로 엔진 시동부는 배터리에서 제공되는 전압이 트랜스포머의 일차측 단자에 입력되고 상기 트랜스포머에 의해 승압되어 점화코일로 제공된다. 그러므로 제어부는 상기 배터리 또는 일차측 단자에 전원을 제공하기 위한 경로에 스위칭 회로를 연결하여 엔진 시동부(140)를 제어할 수 있다.엔진(150)은 엔진제어부(100)의 제어를 받으며 엔진시동부(140)로부터 발생되는 엔진시동 신호에 의해 엔진의 시동이 걸리게 된다.The engine control unit (ECU: ENGINE CONTROL UNIT) 100 controls the overall operation of the vehicle and generates an enable or disable signal according to the measured amount of coolant or oil according to the present invention to control the engine. do. The engine oil sensor 110 measures the amount of engine oil and transmits the amount of engine oil to the engine controller 100. The coolant sensor 120 measures the amount of coolant to prevent overheating of the vehicle and transmits the amount of coolant to the engine controller 100. The transmission oil sensor 130 measures the amount of the transmission oil and transmits the amount to the engine control unit 100. The engine starting unit 140 generates an engine starting signal when the user inserts the start key of the vehicle to start the engine and transmits the generated engine starting signal to the engine 150. The engine starting unit 140 may or may not operate under the control of the engine control unit 100. In general, the engine starter voltage is supplied from the battery to the primary terminal of the transformer and boosted by the transformer to provide the ignition coil. Therefore, the control unit may control the engine starter 140 by connecting a switching circuit to a path for providing power to the battery or the primary terminal. The engine 150 is controlled by the engine control unit 100 while the engine starts. The engine is started by the engine start signal generated from the eastern part 140.

도 2는 본 발명의 실시예에 따라 엔진을 제어하기 위한 제어 흐름도이다.2 is a control flowchart for controlling an engine according to an embodiment of the present invention.

200 단계에서 엔진제어부(100)는 엔진오일 센서(110)로부터 측정된 오일의 양이 기준치 이하인지 검사한다. 측정치가 기준치 이하이면 230 단계로 진행하고 그렇지 않으면 210 단계로 진행한다. 210 단계에서 엔진제어부(100)는 변속기오일 센서(130)로부터 측정된 변속기오일의 양이 기준치 이하인지 검사한다. 측정치가 기준치 이하이면 230 단계로 진행하고 그렇지 않으면 220 단계로 진행한다. 220 단계에서 엔진제어부(100)는 냉각수 센서(120)로부터 측정된 냉각수의 양이 기준치 이하인지 검사한다. 측정치가 기준치 이하이면 230 단계로 진행하고 그렇지 않으면 200 단계로 돌아간다. 230 단계에서 엔진제어부(100)는 도시하지 않은 표시부를 통해 경보 메시지를 발생하거나 도시하지 않은 스피커를 통해 경보음을 발생한다. 240 단계에서 엔진제어부(100)는 디스에이블(DISABLE) 신호를 발생하여 엔진 시동부(140)가 동작하지 못하도록 한다. 이렇게 함으로써 냉각수나 오일이 부족한 상태에서는 엔진의 시동을 걸 수 없게 하였다. 250 단계에서 엔진제어부(100)는 도시하지 않은 입력부를 통해 사용자가 오일이나 냉각수의 부족을 인지하고 엔진시동부(140)에 인에이블 신호가 인가되도록 하는 해제 키 값이 입력되는지 검사한다. 상기 해제키 값이 입력되면 인에이블(ENABLE) 신호를 발생하여 엔진시동부(140)가 동작하도록 한다. 상기와 같은 과정은 운전자가 오일이나 냉각수의 부족을 인지하고 이를 보충하기 위하여 차량을 이동시키는 것을 허용하기 위함이다.In step 200, the engine controller 100 checks whether the amount of oil measured from the engine oil sensor 110 is equal to or less than a reference value. If the measurement is less than the reference value proceed to step 230, otherwise proceed to step 210. In step 210, the engine controller 100 checks whether the amount of the transmission oil measured from the transmission oil sensor 130 is equal to or less than a reference value. If the measurement is less than the reference value proceed to step 230, otherwise proceed to step 220. In step 220, the engine controller 100 determines whether the amount of coolant measured from the coolant sensor 120 is equal to or less than a reference value. If the measurement is less than the reference value, go to step 230; otherwise, return to step 200. In operation 230, the engine control unit 100 generates an alarm message through a display unit not shown or an alarm sound through a speaker not shown. In step 240, the engine controller 100 generates a DISABLE signal to prevent the engine starting unit 140 from operating. This prevented the engine from starting in the absence of coolant or oil. In operation 250, the engine controller 100 determines whether a release key value is input to allow the user to recognize a lack of oil or coolant and to apply an enable signal to the engine starter 140 through an input unit (not shown). When the release key value is input, the engine start unit 140 operates by generating an enable signal. The above process is to allow the driver to move the vehicle to recognize the lack of oil or coolant and to compensate for it.

본 발명의 따른 실시예를 간단하게 설명하면 다음과 같다. 엔진오일이나 변속기 오일 또는 냉각수의 양이 기준치 이하이면 엔진시동부(140)가 동작하지 못하게 한다. 그러나 운전자가 부족을 인지하고 이를 보충하기 위해 해제키를 누르면 차량의 이동을 허용하기 위해 엔진시동부(140)에 인에이블 신호를 인가하여 엔진시동부(140)가 동작하게 한다.An embodiment of the present invention will be described briefly as follows. If the amount of engine oil or transmission oil or cooling water is less than the reference value, the engine starting unit 140 may not operate. However, when the driver recognizes the shortage and presses the release key to compensate for the shortage, the engine starter 140 operates by applying an enable signal to the engine starter 140 to allow movement of the vehicle.
