Description
본 고안은 자동차 주행시 소모되는 연료량과 주행연비를 측정하는 장치에 관한 것으로서, 특히 자동차 내부로부터의 각종 신호를 이용하여 주행시 실시간으로 연료소모량, 연비 및 순간연료소모량을 산출하여 이를 표시하여 줌으로써 운전자로 하여금 자동차를 효율적으로 관리 및 이용하도록 함을 목적으로 한다.The present invention relates to a device for measuring the fuel consumption and driving fuel consumption when driving a vehicle, and in particular, by using various signals from the inside of the vehicle to calculate the fuel consumption, fuel consumption and instantaneous fuel consumption in real time when driving the driver The purpose is to efficiently manage and use a car.
일반적으로 연료소모량의 측정은 연료공급라인에 연료소모량측정기기를 설치하여 측정하였다. 그러나 연료소모량측정기기는 수백 혹은 수천만원의 고가 이어서 자동차 제조사나 자동차 관련 연구소 등에서 엔진개발을 위한 목적으로 사용을 하였고 일반 자동차 운전자들은 자기 자동차의 연료소모량을 아는 것은 거의 불가능하였다. 또한 연비에 관심을 가진 많은 운전자들은 연료소모량과 연비를 구하기 위하여 주유시 연료탱크를 가득 채우면서 주행거리적산계를 0으로 셋팅하고 일정거리를 주행 후 다시 가득 채울 때 주유하게 되는 양을 기준으로 연료소모량과 주행거리를 이용하여 연비를 어림짐작하였다. 그러나 이러한 방법은 측정치가 정확하지 않을 뿐만아니라 실시간으로의 활용이 불가능하고 평균적 의미에 불과하며 실시간적인 정보로서 활용되지 못하고 있다.In general, the fuel consumption was measured by installing a fuel consumption measuring instrument in the fuel supply line. However, the fuel consumption measuring device was expensive for several hundred or tens of millions of won, so it was used for the development of engines by automobile manufacturers and automobile research institutes, and it was almost impossible for ordinary motorists to know the fuel consumption of their cars. In addition, many drivers who are interested in fuel economy use the fuel consumption based on the amount of fuel used to fill the fuel tank during fueling and set the mileage totalizer to 0 and fill it again after driving a certain distance The fuel economy was estimated using the and mileage. However, these methods are not only accurate in measurement, but also impossible to use in real time, mean only mean, and are not used as real time information.
따라서 본 고안은 상기와 같은 문제점을 해결하기 위해 자동차에 장착되어 있는 연료인젝터와 차속 신호를 이용하여 연료소모량과 주행거리를 측정함으로써 추가의 측정기기를 사용하지 않고도 주행에 따른 연료소모량과 연비를 가장 효율적인 방법을 통하여 산출하고, 이를 실시간으로 표시하는 장치를 제공하는데 있다.Therefore, the present invention measures fuel consumption and mileage by using fuel injector and vehicle speed signal installed in a vehicle to solve the above problems, thereby optimizing fuel consumption and fuel efficiency according to driving without using additional measuring device. It is an object of the present invention to provide an apparatus for calculating and displaying in real time through an efficient method.
