Ramp-on coolant temperature display device that allows the driver to more easily recognize the condition of the engine room while driving the vehicle.
최근 자동차의 연료 잔량 및 엔진 냉각수 온도를 체크하여 연료주입시기 및 엔진상태를 메터에 표시하는 계기들이 자동차 발전과 더불어 상당한 발전을 보이고 있다.Recently, the instrument that checks the fuel level and engine coolant temperature of the vehicle and displays the fuel injection timing and the engine status on the meter shows significant progress along with the vehicle development.
이를테면, 자동차를 운전할 때 엔진 냉각수의 적정한 온도유지는 효율적인 연비/출력 등 각종 정보전달장치와 중요한 연관관계를 가지며, 따라서 차량 운행중 엔진의 원활한 구동조건을 나타내는 냉각수 온도정보를 운전자에 제공하게 된다.For example, maintaining the proper temperature of the engine coolant when driving a vehicle has an important relationship with various information transmission devices such as efficient fuel economy / output, thus providing the driver with coolant temperature information indicating smooth driving conditions of the engine while the vehicle is running.
운전자에게 엔진 냉각수의 정보를 전달하는 장치는 운전석 전방의 계기판에 위치하여 엔진 과열시에 게이지의 지침이 움직여서 이상 유무를 표시하도록 되어 있다.The device that transmits the information of the engine coolant to the driver is located in the instrument panel in front of the driver's seat and the gauge is moved when the engine is overheated to indicate the abnormality.
이러한 게이지 지침표시식 냉각수 온도표시장치는 지침 자동한계구간을 그래픽으로 설정하여 정상 상태에서 게이지 지침이 안정구간으로 설정된 특정위치에 머물다가 엔진 과열에 의한 오버히팅 발생시 운전자가 비정상임을 인지할 수 있도록,지침이 붉은 영역에 진입하여 경고의미를 전달하는 표시방식으로 구성되어 있다.The gauge indication type coolant temperature display device sets the automatic limit section graphically so that the operator can recognize the abnormality when the overheating occurs due to overheating of the engine while staying at a certain position where the gauge instruction is set to the stable section in the normal state. Instructions are organized in a display mode that enters the red zone and conveys a warning.
첨부한 도 1 은 종래의 지침표시식 냉각수 온도표시장치를 도시해 놓은 시스템 블럭도로서, 이 지침표시식 냉각수 온도표시장치에서는 시동스위치(1)가 냉각수 온도게이지(2)를 통해 접지되는 한편, 상기 냉각수 온도게이지(2)가 냉각수 온도감지센더(3)를 통해 접지되어있다.1 is a system block diagram showing a conventional guided coolant temperature display device.

또한, 상기 원칩마이콤(8)의 입력단(8a)에는 상기 냉각수 온도감지센더(9)가 연결되는 한편, 그 출력단(8b, 8c)에는 직병렬의 캐패시터(C1), 저항(R1, R2) 및 전계효과 트랜지스터(12)를 매개로 상기 예열램프(10)가, 직병렬의 캐패시터(C2), 저항(R3, R4) 및 전계효과 트랜지스터(13)를 매개로 상기 경고램프(11)가 각각 연결되며, 각 램프(10, 11)는 해당 전계효과 트랜지스터(12, 13)가 통전될 때 이를 통해 접지된다.In addition, the coolant temperature sensing sender 9 is connected to the input terminal 8a of the one-chip microcomputer 8, while the output terminals 8b and 8c have capacitors C1, resistors R1, R2, and The preheat lamp 10 is connected via a field effect transistor 12, and the warning lamp 11 is connected via a capacitor C2, resistors R3 and R4 and a field effect transistor 13 in parallel. Each lamp 10, 11 is grounded through the corresponding field effect transistor 12, 13 when it is energized.
이와 같이 구성되는 본 발명에서는 전원스위치(7)의 시동 온(ON)에 따라 엔진이 작동되고, 냉각수 온도가 점차적으로 상승되면, 이때 엔진 블록에 장착된 냉각수 온도감지센더(9)로부터 클라스터에 내장된 원칩마이콤(8)에 저항이 인가되며,이 원칩마이콤(8)은 저항 변화량을 감지하여 램프점등조건으로 설정된 프로그램 로직에 의해 예열램프 점등신호 또는 경고램프 점등신호를 해당 출력단(8b,8c)을 통해 출력하여, 해당 램프(10, 11)가 점등되게 한다.In the present invention constituted as described above, when the engine is operated according to the start-up of the power switch 7, and the coolant temperature is gradually raised, the coolant temperature sensing sender 9 mounted on the engine block is connected to the cluster. A resistance is applied to the built-in one chip microcomputer 8, and the one chip microcom 8 senses a change in resistance and transmits a preheating lamp lighting signal or a warning lamp lighting signal to the corresponding output terminals 8b and 8c by the program logic set to the lamp lighting condition. ), And the corresponding lamps 10 and 11 are turned on.
본 발명의 램프점등식 냉각수 온도표시장치의 상세조건의 로직을 설명하면, 시동키 온(ON)에 의한 엔진시동상태에서 예열단계의 램프는 첨부한 도 4b에 도시한 TEMP LOW 램프(녹색 점등)를 사용한다.Referring to the logic of the detailed conditions of the lamp-illuminated coolant temperature display device of the present invention, the lamp of the preheating step in the engine starting state by the start key ON is connected to the TEMP LOW lamp shown in FIG. use.
전원스위치(7)의 IGN+가 원칩마이콤(8) 및 냉각수 온도감지센더(9)에 인가되고, 이후 엔진 냉각수가 상승하면, 상기 냉각수 온도감지센더(9)의 저항값이 감소하기 시작한다.IGN + of the power switch 7 is applied to the one-chip microcomputer 8 and the coolant temperature sensing sender 9, and then when the engine coolant rises, the resistance value of the coolant temperature sensing sender 9 begins to decrease.
이때 변화되는 저항치를 상기 원칩마이콤(8)이 연산한 후, 예열점등조건 0∼60℃에서는 예열램프 점등신호를 출력단(8b)으로 출력하여 직병렬의 캐패시터(C1), 저항(R1, R2)을 통해 전계효과 트랜지스터(12)를 통전시키고, 이에 상기 전계효과 트랜지스터(12)를 통한 예열램프(10)가 점등되게 한다.At this time, after the one-chip microcomputer 8 calculates the changed resistance value, the preheat lamp lighting signal is output to the output terminal 8b under the preheating condition 0 to 60 ° C., and the capacitors C1 and R1 and R2 of the parallel and parallel. Through the field effect transistor 12 is energized, the preheat lamp 10 through the field effect transistor 12 is turned on.
한편, 정상온도조건 60∼116℃ 구간에서는 상기 원칩마이콤(8)이 출력신호를 오프하여 비점등상태로 차량을 운행할 수 있도록 한다.On the other hand, in the normal temperature condition 60 ~ 116 ℃ section the one chip microcomputer 8 to turn off the output signal so that the vehicle can run in a non-lit state.
또한, 오버히팅조건 117 ℃ 이상 구간에서는 상기 원칩마이콤(8)이 경고램프 점등신호를 출력단(8c)으로 출력하여 직병렬의 캐패시터(C2), 저항(R3, R4)을 통해 전계효과 트랜지스터(13)를 통전시키므로, 상기 경고램프(11)가 점등되게 된다.Further, in the overheating condition of 117 ° C. or more, the one-chip microcomputer 8 outputs a warning lamp lighting signal to the output terminal 8c to output the field effect transistor 13 through the capacitor C2 and the resistors R3 and R4 in parallel. ), The warning lamp 11 is turned on.
즉, 냉각수의 오버히팅 경고를 위한 상기 경고램프(11)로 도 4b에 도시한 TEMP HIGH 램프(적색 점등)를 사용하여, 운전자에게 경고하게 되는 것이다.That is, the warning lamp 11 for warning of overheating of the coolant is used to warn the driver by using the TEMP HIGH lamp (red light) shown in FIG. 4B.
또한, 오버히팅조건의 경고램프(11)에는 램프의 중요성을 감안하여 그 단락 유무를 쉽게 확인할 수 있도록 시동키 온(ON)시 초기에 소정 시간동안 점등 후 소등되도록 한 지연시간기능을 적용하는 것이 바람직하다.In addition, in order to easily check whether there is a short circuit in consideration of the importance of the lamp, the warning lamp 11 under the overheating condition is to apply a delay time function so that the lamp is turned off and then turned off for a predetermined time at the start-up time. desirable.
첨부한 도 3는 본 발명의 램프점등식 냉각수 온도표시장치를 설명하기 위한 데이터 처리 순서도이고, 도 4a는 본 발명의 램프점등식 냉각수 온도표시장치에서 점등 및 소등의 예를 나타낸 도면이다.FIG. 3 is a flowchart of a data processing for explaining the lamp-type coolant temperature display device of the present invention, and FIG. 4A is a view showing an example of lighting and turning off the lamp-type coolant temperature display device of the present invention.
먼저, 도 3에 도시한 바와 같이, 오버히팅조건의 경고램프(11)는 램프의 단락 유무가 운전자로 하여금 쉽게 확인될 수 있도록 시동키 온(ON)시 초기에 3초 이상 점등 후 소등된다(TEMP HIGH 램프 3초 이상 점등).First, as shown in Figure 3, the warning lamp 11 of the overheating condition is turned off after 3 seconds or more initially at the start-up key (ON) so that the driver can be easily confirmed whether the short circuit of the lamp ( TEMP HIGH lamp lights for more than 3 seconds).
원칩마이콤(8)은 냉각수 온도감지센더(9)에 의한 저항값을 취득한 다음, 구간판정 및 표시출력으로 예열점등조건인 TEMP LOW상태이면 예열램프(10)를 점등시키며(TEMP LOW 램프 점등), 그렇지 않으면 중간안정구간일 때 소등하든지 오버히팅조건인 TEMP HIGH상태이면 경고램프(11)를 점등시킨다.The one-chip microcomputer 8 acquires the resistance value by the coolant temperature sensing sender 9 and then turns on the preheating lamp 10 when the TEMP LOW state is a preheating condition by section determination and display output (TEMP LOW lamp is lit). Otherwise, the warning lamp 11 is turned on when the light is turned off during the middle stability section or when the TEMP HIGH state is an overheating condition.
한편, 도 4a에서 예열램프(10)는 예열점등조건에 해당되는 55℃에서 TEMP LOW로 점등되고, 경고램프(11)는 오버히팅조건에 해당되는 117℃에서 TEMP HIGH로 점등되며, 60℃ 및 112℃에서는 모두 소등되고 있다.Meanwhile, in FIG. 4A, the preheating lamp 10 is lit by TEMP LOW at 55 ° C. corresponding to the preheating condition, and the warning lamp 11 is lit by TEMP HIGH at 117 ° C. corresponding to the overheating condition. All are extinguished at 112 degreeC.
이상에서 살펴본 바와 같이, 본 발명에 따른 램프점등식 냉각수 온도표시장치에 의하면, 종래의 지침표시식 게이지에 비하여, 인식성이 우수할 뿐만 아니라,부품수 및 공수를 축소할 수 있음으로 해서 원가 절감이 가능한 장점이 있게 된다.As described above, according to the lamp-illuminated cooling water temperature display device according to the present invention, not only is it more recognizable than conventional guideline indication gauges, but also the number of parts and man-hours can be reduced, thereby reducing the cost. There is a possible advantage.
또한, 종래와는 달리, 지침 그래픽 표시용 디스플레이 패널과 지침구동용 무브먼트 등의 구조가 삭제될 수 있으므로 중량 저감의 효과도 기대된다.In addition, unlike the related art, structures such as a display panel for displaying a guide graphic and a movement for driving a guide may be deleted, so that the effect of weight reduction is also expected.
