Description

엘피지 차량의 연료 잔량 측정장치{FUEL GAUGING APPARATUS FOR LPG-TYPE VEHICLE}FUEL GAUGING APPARATUS FOR LPG-TYPE VEHICLE}

본 발명은 엘피지 차량의 연료 잔량 측정장치에 관한 것으로서, 보다 상세하게는 LPG 차량의 연료 탱크내의 연료 잔량을 표시함에 있어서, 연료 탱크내에 설치된 연료 잔량 측정기구에 의한 측정방식이 아니고, 연료 탱크로부터 엔진으로 공급된 LPG 가스량을 측정하는 방식을 사용하여, 잔여 연료량을 보다 신뢰도 높게 측정할 수 있도록 하는 엘피지 차량의 연료 잔량 측정장치에 관한 것이다.The present invention relates to an apparatus for measuring fuel residual amount of an LPI vehicle, and more particularly, to displaying the fuel residual amount in a fuel tank of an LPG vehicle, not from a fuel tank measuring engine installed in the fuel tank, but from a fuel tank. By using a method of measuring the amount of LPG gas supplied to the, relates to a fuel remaining amount measuring device of the LLP vehicle to enable a more reliable measurement of the remaining fuel amount.

현재 일반적인 LPG 차량의 연료 탱크(또는 봄베(Bombe))는 원통형의 가스통으로 제작된다. 이러한 형상을 갖는 연료 탱크내에 잔여하는 연료량을 측정하기 위하여, 종래에는 뜨게식의 연료 잔량 측정기가 장착되어 사용되었다.Currently, the fuel tank (or Bombe) of a typical LPG vehicle is made of a cylindrical gas cylinder. In order to measure the amount of fuel remaining in a fuel tank having such a shape, a float fuel level meter has been conventionally used.

이러한 뜨게식 연료 잔량 측정기는 뜨게의 높이에 따라 변하는 저항값을 측정하고 미터셋(Meterset)으로 보내어, 연료의 잔량을 아날로그(Analog)값으로 미터셋상에 표시하는 방식을 취하였다.This float fuel level meter measures the resistance value that changes according to the height of the float and sends it to the meterset, which displays the fuel level on the meter set as an analog value.

그런데, 이러한 종래의 연료 잔량 측정방식은 여러가지 문제점을 안고 있었다.However, such a conventional fuel residual amount measurement method has various problems.

즉, 상기와 같은 방식으로 LPG 가스의 잔량을 표시할 경우, 연료 탱크가 원통형이므로, 차량의 유동에 의해 남은 잔량이 어느 한쪽으로 쏠리는 현상이 발생하여 정확한 연료 잔량을 표시할 수가 없었다. 또한, 연료가 어느 수준에 이른 상태에서 연료 유동이 발생하면, 주유 경고등이 지속적으로 On/Off가 반복되는 경우도 있었다.That is, when displaying the remaining amount of the LPG gas in the above manner, since the fuel tank is cylindrical, the phenomenon that the remaining amount is concentrated to either side due to the flow of the vehicle occurs, it was not possible to display the exact amount of fuel remaining. In addition, when fuel flow occurs while the fuel reaches a certain level, the fueling warning light may be repeatedly turned on and off.

한편, LPG 차량은 연료가 완전히 소모되면 견인을 하여야 하므로, 연료 잔량에 대한 신뢰도가 없는 상태에서는 운전자들은 연료의 완전 소모상태에 대한 불안감을 느끼게 되고, 이로 인해 LPG 충전소가 보이면 잔량에 무관하게 일단 연료 탱크가 충만(Full)된 상태로 충전을 하는 경우가 대부분이었다.On the other hand, LPG vehicles must be towed when the fuel is completely exhausted, so when the fuel level is unreliable, drivers may feel anxious about the exhaustion of the fuel. In most cases, the tank was filled with a full state.

이러한 원인으로 인해 운전자들은 LPG 차량의 유지비가 적은 이점에도 불구하고, 잦은 충전과 충전소 부족에 따른 불안감으로 디젤 혹은 가솔린 차량을 선호하게 되는 실정이었다.For these reasons, despite the low maintenance costs of LPG vehicles, drivers were likely to prefer diesel or gasoline vehicles due to frequent charging and lack of charging stations.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, LPG 차량의 연료탱크내의 연료 잔량을 표시함에 있어서, 연료 탱크내에 설치된 잔량 측정기구에 의한 측정방식이 아니고, 연료 탱크로부터 엔진으로 공급된 LPG 가스량을 측정하는 방식을 사용하여, 연료 잔량을 보다 신뢰도 높게 측정할 수 있도록 하는 엘피지 차량의 연료잔량 측정장치를 제공함을 그 목적으로 한다.The present invention is to solve the above problems, in displaying the fuel residual amount in the fuel tank of the LPG vehicle, the LPG gas amount supplied to the engine from the fuel tank, not the measurement method by the residual amount measuring mechanism installed in the fuel tank It is an object of the present invention to provide an apparatus for measuring fuel residual amount of an LPI vehicle that enables the fuel residual amount to be measured more reliably by using a measuring method.

이하 첨부 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명의 LPG 차량의 연료 잔량 측정장치의 구성도, 도 2는 본 발명의 LPG 차량의 연료 잔량 측정장치의 작동흐름도이다.1 is a configuration diagram of a fuel remaining amount measuring apparatus of the LPG vehicle of the present invention, Figure 2 is a flow chart of the operation of the fuel remaining amount measuring apparatus of the LPG vehicle of the present invention.

본 발명은 LPG 차량의 연료 탱크내의 연료 잔량을 표시하는 방식으로서, 종래와 같이 연료 탱크내에 뜨게식 기구를 삽입하여 저항값으로 출력하는 방식이 아니고, 실제로 연료 탱크로부터 엔진으로 공급되어 소모되는 LPG 가스량을 유량 측정기(가스미터기)를 장착하여 측정하여, 충전량에서 소모된 가스량을 감산하여 역으로 연료 잔량을 측정하는 원리를 이용한다.The present invention is a method of displaying the remaining fuel amount in the fuel tank of the LPG vehicle, and is not a method of inserting a floating mechanism in the fuel tank and outputting the resistance value as in the prior art, but actually the amount of LPG gas supplied and consumed from the fuel tank to the engine Is measured by mounting a flow meter (gas meter), and subtracts the amount of gas consumed from the filling amount and measures the remaining fuel amount in reverse.

이를 위하여, 본 실시예에서는 다음과 같은 측정장치가 구비되는데, 연료 탱크(30)로부터 엔진(10)으로 유입되는 LPG 연료 공급 라인 상에 유량 측정기(20)를 설치하고, 측정된 유량에 대한 신호를 받아 이를 표시하며, 소정의 연산 및 제어기능이 구비된 디스플레이부(40)를 설치한다. 상기 디스플레이부(40)는 입력된 유량신호를 중량(kg) 또는 유량(ℓ)으로 표시하도록 구성되며, 디지털식으로 작동된다.To this end, the present embodiment is provided with the following measuring device, the flow rate meter 20 is installed on the LPG fuel supply line flowing from the fuel tank 30 to the engine 10, the signal for the measured flow rate Receives and displays it, and installs the display unit 40 with a predetermined operation and control function. The display unit 40 is configured to display the input flow signal in weight (kg) or flow rate (L), and is digitally operated.

디스플레이부(40)는 기본적으로 연료 탱크에 잔류하는 연료량을 표시하는 기능을 한다.The display unit 40 basically displays the amount of fuel remaining in the fuel tank.

운전자가 연료 충전소에서 LPG 충전을 시작하면, 디스플레이부(40)는 충전시의 연료 충전량을 Full 충전을 기본으로 가정하여, 자동으로 연료 충만(Full) 상태로 리셋이 되는데, 그 이유는 LPG의 단가와 충전소 사정을 고려시 대부분의 운전자들은 1회 충전시 Full 충전을 하기 때문이다.When the driver starts the LPG charging at the fuel charging station, the display 40 automatically resets the fuel filling state at the time of charging to the fuel full state on the basis of the full charging, because the unit price of the LPG This is because most drivers charge full when they consider charging and charging stations.

LPG 충전시에 운전자는 운전석쪽에 위치한 연료 주입구 오픈 버튼을 조작하여 주입구가 열리도록 하는데, 이때 연료 주입구 오픈 버튼의 누름 신호를 받아 디스플레이부(40)가 연료 충만(Full) 상태로 리셋이 되도록 구성된다.When the LPG is charged, the driver operates the fuel inlet open button located at the driver's seat to open the inlet. In this case, the display unit 40 is configured to be reset to a full state by receiving the push signal of the fuel inlet open button. .

디스플레이부(40)가 운전자의 오조작에 의해 리셋되는 것을 방지하도록 다음과 같은 오조작 방지 기능이 구비된다.In order to prevent the display unit 40 from being reset by a misoperation of the driver, the following misoperation prevention function is provided.

운전자나 혹은 동승자의 실수로 연료 주입구 오픈 버튼을 눌렀을 경우를 대비하여 디스플레이부(40)는 추가 채널을 구비한다.The display unit 40 has an additional channel in case the driver or passenger accidentally presses the fuel inlet opening button.

Cn을 현재 적산된 연료소모량, R을 충전 직전의 소모된 연료량이라고 할 때에, 연료 주입구 오픈 버튼의 누름시 리셋은 Cn 채널에서 이루어지며, 리셋 작동시 Cn 채널에 표시된 데이타는 R 채널로 이전되어, 운전자가 오조작에 의해 Cn 채널을 리셋한 것을 인지한 때에 R 채널에 이전되어 있던 데이타를 다시 Cn 채널로 이전시킬 수 있도록 디스플레이부(40)가 구성된다.When Cn is the current accumulated fuel consumption and R is the amount of fuel consumed just before charging, the reset at the press of the fuel inlet open button is made in the Cn channel, and the data displayed in the Cn channel is transferred to the R channel during the reset operation. When the driver recognizes that the Cn channel is reset by an incorrect operation, the display unit 40 is configured to transfer the data transferred to the R channel back to the Cn channel.

통상적으로 운전자가 차량이 주행중인 경우에 연료 주입구 오픈 버튼을 조작하는 경우는 없으므로, 운전자가 오조작을 다소 늦게 인지하여 상기와 같은 작동이 이뤄지더라도 R 채널에 기억된 데이타를 다시 Cn 채널로 이전하여 계속적으로 연료소모량을 적산하는데 별문제는 없게 된다.In general, since the driver does not operate the fuel inlet open button while the vehicle is running, the driver recognizes a misoperation a little later and transfers the data stored in the R channel back to the Cn channel even when the above operation is performed. There is no problem in integrating fuel consumption continuously.

한편, 차량의 연비계산을 위하여 디스플레이부(40)는 또다른 추가 채널을 구비한다.Meanwhile, the display unit 40 includes another additional channel for calculating fuel economy of the vehicle.

T를 총 연료소모량이라고 할 때, 디스플레이부(40)는 T 채널을 추가로 구비하게 되며, 본 채널에서는 전체 연료사용량이 누적 표시된다. 상기 T 채널에는 리셋 버튼이 구비되어 운전자의 조작시 제로(0)로 리셋이 되도록 하여 리셋한 후부터 다음 리셋시까지의 연료사용량이 누적 표시되게 된다.When T is referred to as the total fuel consumption amount, the display unit 40 further includes a T channel, in which the total fuel use amount is accumulated and displayed. The T channel is provided with a reset button so as to be reset to zero when the driver operates, so that the fuel usage amount from the reset to the next reset is accumulated.

차량에는 일반적으로 연료 부족 경고등이 구비되는데, Full 충전시의 연료 탱크 용량은 연료 탱크의 설계시에 세팅되는 값이므로, 이값을 F 라는 값으로(차종/엔진별로 세팅값이 다름) 디스플레이부(40)에 저장되게 한다.Vehicles are usually equipped with a low fuel warning light, and the fuel tank capacity at full filling is a value that is set at the time of designing the fuel tank. Therefore, this value is set to F (the setting value is different for each model / engine). To be stored).

1회 충전후 적산된 LPG 연료 소모량을 Cn 이라 하고, 경고등이 점등되어 운전자에게 재충전 시기를 알려주는 잔량을 W(잔량으로 주행가능한 거리를 산정하여 차종별로 세팅됨)라 하면, 경고등의 점등시점은 하기의 로직에 따라 구해진다.If the accumulated LPG fuel consumption after one charge is Cn, and the warning light is turned on to inform the driver of the recharging time, the remaining amount is W (set by calculating the distance that can be driven by the remaining amount), then the warning light turns on. Obtained according to the following logic.

If W = F - CnIf W = F-Cn

then Warning = Onthen Warning = On

else Warning = Offelse Warning = Off

이러한 로직에 의해 잔량이 W에 도달한 것이라고 판단되면, 디스플레이부(40)에 구비된 경고등이 점등되어 운전자에게 연료 잔량에 대한 경고 신호를 보내게 된다.If it is determined by the logic that the remaining amount has reached W, the warning light provided in the display unit 40 is turned on to send a warning signal for the remaining fuel amount to the driver.

한편, 본 발명의 구체적인 구성의 각각은 상기한 실시예의 형태에 한정되는 것이 아니고, 본 발명의 기술적 사상으로부터 벗어나지 않는 범위에서 다양한 변형이 가능하며, 이러한 변형실시는 본 발명에서 권리로서 청구하는 기술적 사상의 범위내에 물론 포함되는 것이다.On the other hand, each of the specific configuration of the present invention is not limited to the embodiment described above, various modifications are possible within the scope without departing from the technical spirit of the present invention, this modification is a technical idea claimed as a right in the present invention Of course it is included in the scope of.
