본 발명은 스마트폰을 이용한 차량용 에코드라이브 인디케이터에 관한 것으로, 더욱 상세하게는 스마트폰에 내장된 GPS와 중력센서로부터 각각 차속과 도로경사를 검출하고, 이들 데이터로부터 연료소모량을 연산하여 운전자가 시각적으로 알 수 있도록 보여줌으로써, 연비향상효과를 통하여 경제적이면서도 친환경적으로 주행 가능하도록 한 스마트폰을 이용한 차량용 에코드라이브 인디케이터에 관한 것이다.The present invention relates to a vehicle eco-drive indicator using a smart phone, and more particularly, the vehicle speed and road slope are detected from the GPS and gravity sensor built in the smart phone, and the fuel consumption is calculated from these data. The present invention relates to an eco-drive indicator for a vehicle using a smartphone that enables economical and eco-friendly driving through an improved fuel economy.

최근 들어 자동차 업계에도 연비절약과 친환경을 목적으로 하는 에코드라이빙 운동이 많이 전개되고 있다. 에코드라이빙이란 절약(ECOnomical) 또는 친환경(ECOlogic)의 에코(ECO)와 운전(Driving)의 합성어로서 경제적이면서도 친환경적인 운전법을 말한다.Recently, many eco-driving movements have been developed in the automobile industry for the purpose of fuel efficiency and eco-friendliness. Eco-driving is a compound word of ecological and ecological and ecological driving.

이러한 친환경 경제운전법인 에코드라이빙은 경제속도(시속 60~80㎞/h)의 준수, 내리막길에서 가속패달을 밟지 않기, 공회전의 최소화, 적절한 타이어 공기압의 유지, 그리고 유사연료?첨가제 사용금지와 같이 연비 저감 효과와 함께 친환경적인 요소를 띄는 운동을 많이 전개하고 있다.Eco-driving, an eco-friendly driving method, is designed to comply with economic speeds (60 to 80 km / h), avoid accelerating downhills, minimize idling, maintain proper tire pressure, and prohibit the use of similar fuels and additives. In addition to reducing fuel consumption, there are a number of campaigns that are environmentally friendly.

이에 부응하여 차량에는 운전자가 실시간으로 연비소모량을 시각적으로 확인하여 에코드라이빙이 가능하도록 안내할 수 있는 에코드라이브 인디케이터가 다양하게 개발되어 시판되고 있다.In response to this, a variety of eco-drive indicators have been developed and marketed in the vehicle to guide drivers to visually check fuel consumption in real time to enable eco-driving.

하지만, 종래의 에코드라이브 인디케이터는 다음과 같은 문제점이 있었다.However, the conventional eco-drive indicator has the following problems.

1) 독립된 하나의 장치로서 구성되어 있기 때문에 차량에 장착하는데 어려움이 있을 뿐만 아니라, 네비게이션과 같은 다른 장비와 동일 기능을 포함하는 경우가 발생하였다.1) Because it is configured as an independent device, it is not only difficult to install in a vehicle, but also includes the same function as other equipment such as navigation.

2) 에코드라이브 인디케이터를 차량운행기록장치(OBD)에 연결하여 사용하여야 하기 때문에, 차량운행기록장치가 없는 차량에는 장착하여 사용할 수 없는 문제가 발생하였다.2) Since the eco-drive indicator has to be connected to the vehicle driving recorder (OBD), the vehicle cannot be installed and used in a vehicle without the driving recorder.

3) 장비가 고가로서 전차종에 대하여 장착하는데 어려움이 있었다.3) The equipment was expensive, so it was difficult to install it on all models.

본 발명은 이러한 점을 감안하여 안출한 것으로, 통상적으로 개인이 항상 소지하고 있는 스마트폰을 이용하여 차량의 연료소모량과 같은 연비데이터를 출력할 수 있게 함으로써, 별도의 장비없이도 운전자에게 연비관련 데이터를 제공하여 친환경적이면서도 경제적인 운행이 가능하도록 한 스마트폰을 이용한 차량용 에코드라이브 인디케이터를 제공하는데 그 목적이 있다.The present invention has been made in view of this point, and by using the smart phone that is always owned by the individual can output the fuel consumption data such as fuel consumption of the vehicle, thereby providing fuel-related data to the driver without any additional equipment The purpose of the present invention is to provide an eco-drive indicator for a vehicle using a smartphone, which enables eco-friendly and economical operation.

이러한 목적을 달성하기 위한 본 발명에 따른 스마트폰을 이용한 차량용 에코드라이브 인디케이터는, GPS센서를 이용하여 차속을 검출하고, 차량의 도로경사각을 검출하는 중력센서가 구비된 스마트폰; 차속과 도로경사각을 이용하여 연비데이터를 연산하는 연산부; 및 연산부로부터 연산된 연산데이터를 출력시켜 주는 디스플레이;를 포함하여 이루어진 것을 특징으로 한다.An eco-drive indicator for a vehicle using a smart phone according to the present invention for achieving the above object comprises: a smart phone having a gravity sensor for detecting a vehicle speed using a GPS sensor and detecting a road inclination angle of the vehicle; A calculation unit which calculates fuel efficiency data using a vehicle speed and a road inclination angle; And a display for outputting calculation data calculated from the calculation unit.

특히, 연비데이터는 연료소모량, 연료소모량히스토그램, 순간연비데이터, 평균연비데이터, 및 차속 데이터 중에서 적어도 하나를 포함하는 것을 특징으로 한다.In particular, the fuel economy data includes at least one of fuel consumption, fuel consumption histogram, instantaneous fuel efficiency data, average fuel efficiency data, and vehicle speed data.

The GPS sensor 110 is used to obtain a vehicle speed through the position detection of the vehicle (V). For example, the vehicle speed is calculated by calculating the distance using the position of the vehicle V per unit time.

<제2실시예>&Lt; Embodiment 2 >

도 3은 본 발명의 제2실시예에 따른 스마트폰을 이용한 차량용 에코드라이브 인디케이터의 구성을 보여주기 위하여 개략적으로 도시한 블럭도이다. 여기서, 상술한 제1실시예와 동일 구성에 대해서는 동일부호를 사용하고 그 상세한 설명을 생략한다.3 is a block diagram schematically illustrating a configuration of an eco-drive indicator for a vehicle using a smartphone according to a second embodiment of the present invention. Here, the same components as those in the above-described first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

본 발명의 제2실시예에 따른 스마트폰을 이용한 차량용 에코드라이브 인디케이터(1000')는, 제1실시예와 비교해 볼 때, 연산부(200')와 디스플레이(300')의 구성에 있어서 차이가 있다. As compared with the first embodiment, the vehicle eco-drive indicator 1000 'using the smart phone according to the second embodiment of the present invention has a difference in the configuration of the operation unit 200' and the display 300 '. .

즉, 제1실시예의 연산부(200)와 디스플레이(300)는 별도로 구성된 것을 이용하고 있으나, 제2실시예에서는 스마트폰(100')에 구비된 연산부(200')와 디스플레이(300')를 이용하여 연산데이터의 연산과 그 결과를 디스플레이시켜주도록 구성한 것이다.That is, the calculation unit 200 and the display 300 of the first embodiment are used separately, but in the second embodiment, the calculation unit 200 'and the display 300' provided in the smartphone 100 'are used. To display the operation of the operation data and the result.

여기서, 연산부(200')는 통상적으로 스마트폰(100)에 탑재되는 프로세서로서, 스마트폰(100) 전반을 제어하는 하드웨어적인 CPU 뿐만 아니라 이 CPU에 설치된 OS에 장착되는 소프트웨어일 수도 있다.Here, the operation unit 200 ′ is typically a processor mounted in the smartphone 100, and may be software installed in an OS installed in the CPU as well as a hardware CPU that controls the entire smartphone 100.

그리고, 디스플레이(300')는 스마트폰(100)의 메뉴 등을 보여주기 위하여 구성되는 화면을 그대로 이용한다.
In addition, the display 300 ′ uses a screen configured to show a menu of the smartphone 100 and the like.

이에 별도의 장비가 없이도 스마트폰(100)을 차량(V)의 거치대에 거치시키게 되면 에코드라이빙이 가능하게 되는 것이다.
Therefore, if the smart phone 100 is mounted on the cradle of the vehicle V without additional equipment, eco-driving is possible.
