BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fuel efficiency comparison system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle fuel efficiency comparison system and a service method thereof, and more particularly, to a vehicle fuel efficiency comparison system and a service method for comparing fuel efficiency based on actual vehicle driving information.

Recently, various attempts have been made to improve the fuel efficiency of vehicles due to rising oil prices and environmental problems. In order to improve the fuel efficiency, it is important to measure the fuel efficiency of the vehicle. Generally, there are various fuel consumption measuring methods of the vehicle. For example, the carbon balance method sets a certain situation in the laboratory, And the fuel consumption is calculated by measuring the fuel consumed. That is, since the carbon balance method is performed in a laboratory environment instead of measuring the fuel consumption as the vehicle actually travels on the road, the measured fuel consumption may be different from the actual fuel consumption on the road.

Another measurement method is hybrid fuel consumption measurement method. This measurement system calculates 55% and 45% of the fuel consumption for the city and the highway, respectively, and the fuel consumption is calculated as follows: urban driving (FTP-75), high speed driving section (HWFET), deceleration (US06) SC03), and low-temperature urban driving (Cold FTP-75).

However, such conventional fuel consumption measuring methods have a problem in that it is not possible to calculate the fuel consumption of the vehicle in actual operation, or to use it as a comparison data of actual vehicle fuel consumption according to the driving habits or the driving environment of the user.

In addition, the GPS receiving unit 210 may receive position information of the surrounding gas station when the user feeds fuel.

The fuel information obtaining unit 220 may receive the fuel information from the user or obtain the fuel information by estimating the gas station information based on the received GPS information.

Alternatively, when the control unit 330 receives the fuel consumption comparison request from the user terminal 200, the control unit 330 may request to update the vehicle driving information stored in the user terminal 200 and the calculated fuel consumption information. Here, the information updated in the user terminal 200 is information accumulated in the user terminal 200 after the previous update. At this time, if the vehicle driving information of the user terminal 200 and the calculated fuel efficiency information are updated in response to the update request, the controller 330 controls the comparison and diagnosis of the fuel efficiency, As shown in FIG.

The fuel consumption comparing unit 340 compares the fuel consumption calculating condition of the user terminal 200 with the condition of at least one of the vehicle type, date, time, area, speed, RPM or fuel information according to the fuel consumption comparison request of the user terminal 200 It is possible to perform the fuel consumption comparison by searching the database 400 for the reference fuel efficiency by the matching condition.

[ The reason why the fuel consumption comparison is performed according to various conditions in this embodiment is that the actual fuel consumption may vary depending on the driving situation of the vehicle. For example, the fuel consumption of the low-speed section and the high-speed week is different from that of the vehicle after the vehicle departs, and the fuel consumption differs depending on whether the vehicle is accelerating or decelerating at the same speed section. Depending on whether the speed change ratio is uphill or downhill at the same speed section, And the fuel consumption may be different depending on the quality of the fuel. Therefore, in the embodiment of the present invention, the fuel consumption can be compared according to the condition based on the vehicle driving information for comparing the fuel consumption considering various driving situations.

That is, the diagnosis unit 350 can diagnose the cause information of the fuel consumption difference between the fuel consumption calculated in the user terminal 200 and the reference fuel consumption stored in the database 400 based on the calculated comparison result. For example, the diagnosis unit 350 can diagnose fuel quality by comparing the fuel consumption according to the fuel difference, and can diagnose driving habits such as rapid acceleration or sudden start through the fuel consumption comparison rate and the rate change rate have.

Referring again to FIG. 1, the database 400 may store the reference fuel consumption information calculated by the fuel consumption comparison server 300.

The database 400 may include reference fuel economy information 410 and log information 420.

The reference fuel economy information 410 may store reference fuel economy information by condition. For example, the reference fuel economy information 410 may be reference fuel economy information calculated for each vehicle type, date, time, area, speed, RPM, and fuel information.

The log information 420 may store time information that the user terminal 200 last updated the vehicle driving information and the calculated fuel economy to the fuel consumption comparison server 300. [

With such a configuration, the vehicle fuel consumption comparison system and the service method according to an embodiment of the present invention can provide an actual customized fuel consumption comparison through comparison with a reference fuel consumption similar to a user's driving environment, It is possible to diagnose the cause of the problem and to improve the user's driving habits.

Hereinafter, the vehicle fuel consumption comparison service method 500 of the present invention will be described with reference to FIG. 5 is a flowchart illustrating a vehicle fuel consumption comparison service method according to an embodiment of the present invention.

[

Next, based on the compared fuel economy results, the cause of the fuel economy difference or the driving habits of the user can be diagnosed (step S510). That is, based on the comparison result calculated by the fuel consumption comparison server 300, the cause information of the fuel consumption difference between the fuel consumption calculated by the user terminal 200 and the reference fuel consumption stored in the database 400 can be diagnosed. For example, the fuel consumption comparison server 300 can diagnose fuel quality by comparing the fuel consumption according to the fuel difference, and diagnose driving habits such as rapid acceleration or sudden increase through the fuel consumption comparison rate and the speed change rate by the speed .
