As shown, first, when the electronic control system of the vehicle and the terminal according to the present invention are connected by wire or wirelessly through the connector unit 210, various vehicle information measured from the electronic control system can be received ( S1). As such, when connected to the electronic control system, the controller 260 may acquire the speed information of the vehicle and the fuel injection amount information for the engine together with the time information through the connector 210 (S3). Then, the fuel injection amount information is classified into first sub fuel injection amount information and second sub fuel injection amount information, and the speed information is divided into high speed information and low speed information (S5).

Hereinafter, a method of classifying fuel injection amounts in a fuel injection amount data processing method in a terminal according to the present invention will be described with reference to FIG. 3.

3A and 3B are diagrams for explaining a first embodiment and a second embodiment of a method for classifying fuel injection amounts in a fuel injection amount data processing method in a terminal according to the present invention, respectively.

In FIG. 3A, a method of classifying first sub fuel consumption information and second sub fuel consumption information based on a speed is described. FIG. 3B illustrates first sub fuel consumption information based on a gear ratio of a vehicle. Note that a method of classifying the second sub fuel consumption information is described.

As shown in FIG. 3A, first, it is checked whether the speed information obtained from the connector unit 210 is larger or smaller than the reference speed (S51). If the real-time speed information obtained from the connector unit 210 is larger than the reference speed, the speed information is recognized as high speed information, and the fuel injection amount information according to the high speed information is recognized as the first sub fuel injection amount information and integrated. (S53, S55). Next, using the high speed information and the first sub-fuel injection amount information, first fuel efficiency information which is high speed fuel efficiency information is generated (S57). That is, since the fuel injection amount information may be defined as injection amount / time, and the high speed information is defined as distance / time, the first fuel efficiency information may be defined as high speed information / first fuel injection amount information.

On the other hand, if the real-time speed information obtained from the connector unit 210 is smaller than the reference speed, the speed information is recognized as low speed information, and the fuel injection amount information according to the low speed information is recognized as the second sub fuel injection amount information. Integration is performed (S53 ', S55'). Next, using the low speed information and the second sub-fuel injection amount information, first fuel efficiency information which is low speed fuel efficiency information is generated (S57). That is, since the fuel injection amount information may be defined as injection amount / time, and the high speed information is defined as distance / time, the second fuel efficiency information may be defined as low speed information / second fuel injection amount information.

Here, the criterion for determining whether the vehicle is low speed or high speed may be 50 km / h, which is the lower limit speed of the highway. It is obvious that the reference speed may be changed according to the road conditions of each country or the road rules.

Here, if the time information is, for example, 1 second or less, fuel efficiency information can be obtained in real time. If the time information is 1 hour, average fuel efficiency information for 1 hour can be obtained.

Meanwhile, in FIG. 3B, the first fuel efficiency information and the second fuel efficiency information may be obtained based on the gear ratio. Looking in more detail, as shown in Figure 3b, first, it is checked whether the gear ratio information obtained from the connector unit 210 is larger or smaller than the reference gear ratio (S61). For example, if the vehicle is equipped with a five-speed automatic transmission, if the gear ratio is four or more, it will be said to be greater than the reference gear ratio, and if it is three or less, it will not be greater than the reference gear ratio. If the real-time gear ratio information obtained from the connector unit 210 is larger than the reference gear ratio, the speed information at this time is recognized as high speed information, and the fuel injection amount information according to the high speed information is recognized as the first sub fuel injection amount information and accumulated therein. (S63, S65). Next, using the high speed information and the first sub-fuel injection amount information, first fuel efficiency information which is high speed fuel efficiency information is generated (S67). That is, since the fuel injection amount information may be defined as injection amount / time, and the high speed information is defined as distance / time, the first fuel efficiency information may be defined as high speed information / first fuel injection amount information.

On the other hand, if the real-time speed information obtained from the connector unit 210 is smaller than the reference speed, the speed information is recognized as low speed information, and the fuel injection amount information according to the low speed information is recognized as the second sub fuel injection amount information. Accumulation is performed (S63 ', S65'). Next, the first fuel efficiency information, which is low fuel efficiency information, is generated using the low speed information and the second sub fuel injection amount information (S67 '). That is, since the fuel injection amount information may be defined as injection amount / time, and the high speed information is defined as distance / time, the second fuel efficiency information may be defined as low speed information / second fuel injection amount information.

Here, the determination criteria of the low speed or the high speed is determined whether the automatic transmission is four or more in the case of the five-speed transmission, but if the automatic transmission is six or more or four-speed, the reference gear ratio may be changed. will be.

In addition, the high speed fuel economy and the low speed fuel economy may be classified by using the driving pattern stored in the memory 220. The memory 220 may store information regarding the high speed traveling pattern and the low speed traveling pattern. Then, the controller 260 may determine whether the driving state of the vehicle is a high speed driving state or a low speed driving state by using the speed information obtained from the connector unit 210. Based on this, the control unit may check the low speed driving and the high speed driving state, and calculate the fuel efficiency information by classifying them.

Hereinafter, an embodiment of a terminal for calculating a fuel consumption amount of a vehicle, which is an embodiment of the present invention having the above-described configuration, will be described in detail with reference to FIG. 4.

4 is an image diagram illustrating a screen displayed on the display unit 230 of a terminal for calculating a fuel consumption amount of a vehicle according to the present invention. As shown, the high speed fuel economy instrument panel 310 and the low fuel economy instrument panel 320 are displayed in a circle on the display unit 230 of the terminal, and the hour hand included in each fuel economy instrument panel indicates fuel efficiency. In this case, the fuel efficiency information may be real-time fuel efficiency information, or may be fuel efficiency information accumulated within a predetermined time.

Although FIG. 5 illustrates an example in which the fast fuel economy and the low fuel economy are displayed in an analog manner, the fast fuel economy and the low fuel economy may be displayed in a digital manner represented by a number or a mixed method of both.

In addition, although FIG. 5 illustrates the display unit 230 of the terminal for calculating the fuel consumption amount of the vehicle, which is an embodiment of the present invention, as described above, when there is no display unit 230 in the present invention, the high-speed fuel economy It may be displayed in a navigation or the like that has received the information (highway fuel economy information) and low speed fuel economy information (city running fuel economy information).

As in this example, the fuel efficiency information may be displayed as a distance per fuel consumption, or may be displayed as a fuel consumption per hour.

According to one embodiment of the present invention having the above-described configuration, it is possible to obtain fuel economy information according to the driving state of the vehicle, it is possible to provide information to have a good fuel economy habit to the vehicle driver or the owner.
