Description
본 발명은 차량의 주행가능거리 측정시스템에 관한 것으로, 보다 상세하게는 시뮬레이션을 통해 주행모드에 따른 연료소모량을 정확히 측정하여 실제 차량과의 오차 영역을 줄일 수 있도록 된 차량의 주행가능거리 측정시스템에 관한 것이다.The present invention relates to a driving distance measurement system of a vehicle, and more particularly, to a driving distance measurement system of a vehicle capable of reducing an error area with an actual vehicle by accurately measuring fuel consumption according to a driving mode through simulation. It is about.
일반적으로 자동차는 가솔린이나 중유등의 연료를 연소시켜 그때 발생되는 구동력으로 움직이도록 된 동력장치로서 장시간 운용에 필요한 연료를 저장할 수 있는 연료탱크를 구비하고 있으며, 이와 같은 자동차의 연료는 그 사용량이 운전석의 전방에 설치된 연료량 계기에 의하여 표시되고, 이러한 게이지는 연료탱크내에 설치된 연료 게이지 센서와 연결되어, 연료탱크내에 설치된 연료 게이지 센서에 의한 연료량의 측정에 의하여 운전자가 연료 사용량을 인식할 수 있도록 연료량 계기에 의하여 표시된다.In general, a car is a power device that burns fuel such as gasoline or heavy oil and moves with driving force generated at that time, and has a fuel tank capable of storing fuel required for long-term operation. Displayed by the fuel gauge installed in front of the fuel gauge, the gauge is connected to the fuel gauge sensor installed in the fuel tank, fuel gauge so that the driver can recognize the fuel consumption by measuring the fuel amount by the fuel gauge sensor installed in the fuel tank Is indicated.
이와 같은 차량은 차량의 성격이나 능력을 나타내는 차량의 주행 성능 중 차량의 동력 성능은 기관에서 발생하는 동력에 의해 발휘할 수 있는 주행 성능 즉, 구동력에 의한 가속 성능, 최고 속도,등판 성능 등을 말하며, 이 밖에 보조적으로 타행 성능이나 연료 소비 성능 등이 포함되는데, 이중, 연료 소비 성능은 차량의 사용면에서 그 경제성을 평가하는데 매우 중요하며, 연료 소비 성능을 나타내는 지수 중에는 연비(Fuel consumption ratio) 등이 있다.In such a vehicle, the driving performance of the vehicle, which represents the characteristics and capabilities of the vehicle, refers to driving performance that can be exerted by the power generated by the engine, that is, acceleration performance, driving speed, climbing performance, etc. In addition, it includes auxiliary performance, fuel consumption performance, etc. Among these, fuel consumption performance is very important for evaluating the economics in terms of vehicle use, and fuel consumption ratio is one of the indexes indicating fuel consumption performance. have.
이와 같은 연비는 차량의 주행에 따라 소비되는 연료량을 나타내는 지수로서, 차량의 주행 거리를 소비된 연료량으로 나누어계산하고, 그 단위는 연료 1ℓ 당 주행한 ㎞ 를 나타내는 ㎞／ℓ 로 표시한다. 이러한 연비는 운전자가 차량 구입시에주행 성능을 판단하는 지표로 이용되며, 연비가 높은 차량일수록 연료가 적게 드는 차량을 뜻함은 물론이다.Such fuel economy is an index indicating the amount of fuel consumed in accordance with the running of the vehicle. The fuel consumption is calculated by dividing the running distance of the vehicle by the amount of consumed fuel, and the unit is expressed as km / l representing the km traveled per liter of fuel. This fuel economy is used as an indicator for the driver to determine the driving performance when the vehicle is purchased, the higher fuel economy of the vehicle means less fuel.
그러나, 자동차가 포장된 도로를 주행하는 것과 비포장 도로와 같은 울퉁불퉁한 길을 주행할 때나 또는 자동차의 급 출발 또는 급 제동시에 연료 탱크 내에 설치된 연료 게이지 센서가 플로터의 유동에 의하여 유동되므로, 연료탱크 내에 설치된 연료 게이지 센서에 의하여 측정되는 측정값은 오차가 발생되는데, 이와 같은 오차로 인하여 특히, 위성등을 이용한 운행 정보 시스템의 도입을 앞둔 시점에서 자동차의 주행중에 소모되는 정확한 연료 사용량을 기초로 하는 연비 또는 주행 거리를 정확히 표시할 수 없다는 문제가 존재하였다.However, since the fuel gauge sensor installed in the fuel tank flows by the flow of the plotter when the vehicle is driving on a paved road and a bumpy road such as an unpaved road, or at the time of rapid starting or braking of the vehicle, the fuel tank sensor flows by the flow of the plotter. The measurement value measured by the installed fuel gauge sensor causes an error, and due to such an error, fuel economy based on the exact amount of fuel consumed while driving the vehicle, especially at the time ahead of the introduction of a driving information system using satellite lights. Or there was a problem that can not accurately display the driving distance.
이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 트립(Trip)컴퓨터를 이용하여 실제 차량의 운행 조건에 따라 항상 정확한 연비를 측정함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and an object thereof is to always measure accurate fuel economy according to the actual driving conditions of a vehicle using a trip computer.

본 발명은 연료라인을 통해 연료탱크(11)의 연료를 엔진(12)으로 공급해 엔진(12)을 작동시키는데 이때, 상기 연료탱크(11)와 엔진(12)사이의 연료라인에 구비된 레귤레이터밸브(13)는 엔진(12)의 초기 시동 시 연료탱크(11)내로의 연료 리턴(Return)방지와 더불어 엔진작동에 따른 연료 라인압력에 의한 과 압력의 연료를 연료탱크(11)로 복귀시키게 된다.The present invention operates the engine 12 by supplying fuel from the fuel tank 11 to the engine 12 through a fuel line, wherein the regulator valve is provided in the fuel line between the fuel tank 11 and the engine 12. 13 is to prevent the return of fuel into the fuel tank (11) at the initial start of the engine 12, and to return the overpressure of the fuel by the fuel line pressure due to the engine operation to the fuel tank (11). .
이와 같이, 상기 엔진(12)이 작동하게 되면 연료라인을 흐르는 연료 량을 연료소모측정수단(20)의 플로우디텍터(21)가 그 량을 측정해 플로우미터(22)를 통해 산출해 표시수단(40)의 제1표시기(40a)로 디스플레이(Display)함과 동시에 연비측정수단(30)의 트립컴퓨터(32)로 전송하게 된다.As described above, when the engine 12 is operated, the flow detector 21 of the fuel consumption measuring means 20 calculates the amount of fuel flowing through the fuel line through the flow meter 22 to display the amount of fuel flowing through the fuel line. The first display 40a of the display 40 displays and transmits the same to the trip computer 32 of the fuel economy measurement means 30.

In addition, it is possible to calculate the running distance with respect to the remaining fuel amount of the fuel tank 11 measured by the fuel meter (33).
또한, 차량의 도로 조건에 따른 엔진(12)의 연료 소모량과 연비등을 측정하고자 하면, 상기 조건변경수단(60)의 도로조건변환기(60b)에서 도로 조건상황을 선택해 ECU(14)에 전송해 엔진(12)의 작동을 제어하게 되고, 이에 따라 인젝터의 연료 분사에 따른 펄스 신호를 전술한 바와 같이 연비측정수단(30)의 트립컴퓨터(32)가 연료소모측정수단(20)의 플로우미터(22)에 의해 측정된 연료소모량과 비교·분석해 연비를 산출함과 더불어 연료측정기(33)에 의해 측정된 연료탱크(11)의 잔존 연료 량에 대한 주행 가능거리를 산출하게 됨은 물론이다.In addition, when the fuel consumption and fuel economy of the engine 12 according to the road conditions of the vehicle are to be measured, the road condition condition is selected by the road condition converter 60b of the condition changing means 60 and transmitted to the ECU 14. The operation of the engine 12 is controlled, and accordingly, the trip computer 32 of the fuel economy measuring means 30 transmits the pulse signal according to the fuel injection of the injector to the flow meter of the fuel consumption measuring means 20. Comparing and analyzing the fuel consumption measured by 22), the fuel consumption is calculated, and the driving distance of the remaining fuel amount of the fuel tank 11 measured by the fuel meter 33 is, of course, calculated.
이와 같이, 본 발명은 차량의 운전모드와 도로 조건등과 같이 실제 발생되는 조건에 따른 주행가능거리를 정확하게 산출할 수 있게 되므로 결국, 엔진의 특정 운전 조건에서 갖는 연료소모에 따른 주행가능거리와, 일전 속도로 일정 거리의 주행 시 발생되는 연료소모에 따른 평균연비산출 및 엔진의 순간연비 산출은 물론 일정 연료에 의한 차량의 평균속도 산출과 연료의 완전 소모시 까지의 주행가능시간과 거리등을 정확하게 산출할 수 있게 됨은 물론이다.As described above, the present invention can accurately calculate the driving distance according to the actual conditions such as the driving mode and the road conditions of the vehicle, and thus, the driving distance according to the fuel consumption in the specific driving conditions of the engine, Accurate calculation of average fuel efficiency and engine instantaneous fuel consumption according to fuel consumption generated at a certain distance at a certain speed, as well as calculation of the average speed of a vehicle by a certain fuel and the running time and distance until the fuel is completely consumed Of course, it can be calculated.
이상 설명한 바와 같이 본 발명에 의하면, 실제 주행 상황과 같도록 운전모드와 도로조건에 따른 특정 상황을 엔진에 적용시킨 상태에서 엔진의 작동에 따라 연료탱크에서 공급되는 연료 량과 엔진에서 실제로 소모되는 연료 량을 각각 측정해 트립컴퓨터를 통해 서로 비교·분석해 정확한 연비를 산출하는 한편, 엔진의 특정 운전 조건에서 갖는 연료소모에 따른 주행가능거리와 평균연비 및 순간연비 산출등과 같은 데이터를 정확하고 신뢰성있게 측정할 수 있는 효과가 있게 된다.As described above, according to the present invention, the amount of fuel supplied from the fuel tank and the fuel actually consumed by the engine according to the operation of the engine in a state in which a specific situation according to the driving mode and road conditions are applied to the engine to be identical to the actual driving situation Each vehicle is measured and compared to each other through a trip computer to calculate accurate fuel economy, while accurate and reliable data such as the mileage, average fuel efficiency and instantaneous fuel economy calculation according to the fuel consumption under specific engine operating conditions There is a measurable effect.
