## Background
CROSS-REFERENCE(S) TO RELATED APPLICATION(S)
This application claims the benefit of priority to Korean Patent Application No. 10-2014-0149707 filed on Oct. 31, 2014, the entire content of which is incorporated herein by reference.
TECHNICAL FIELD
The present disclosure relates to guiding economic driving, and more particularly, to a system for guiding economic driving using a high pass system, a vehicle applied to the same, and a method thereof.
BACKGROUND
With the development of a hybrid vehicle or an electric vehicle using an environmentally-friendly technology, a technology of increasing energy efficiency of various kinds of vehicles including the existing vehicle using fossil fuel is also important in environment conservation and energy saving.
Accordingly, a method of improving fuel efficiency of a vehicle itself and an economic driving system by an operation of a driver have been developed.
The economic driving system informs various driving conditions of a driver by additionally installing various types of sensors in the vehicle to assist the driver to perform economic driving meeting surrounding traffic conditions in real time.
If the driver is not aware of an economic driving method, the economic driving system relies on only a manual operation of the driver, and therefore, an economic effect due to fuel saving does not appear.
Further, since the economic effect variously appears according to a driving skill, it is difficult to maximize energy efficiency.
The fuel efficiency method of the vehicle itself is a fuel efficiency authentication method which increases the energy efficiency to increase a driving distance to fuel efficiency.
However, as various research results, it is more efficient for the driver to actively guide fuel efficiency driving than improving fuel efficiency and reducing pollutants by the improvement in a vehicle technology.
In other words, a vehicle controller calculates instant fuel consumption and transmits the calculated value to a cluster so that a driver is aware of fuel efficiency for himself/herself. Therefore, a reward system of allowing a driver to use fuel consumption information depending on the fuel efficiency to perform the economic driving is required.

The vehicle terminal 130 communicates with the vehicle 110 to transmit the driving information stored in the vehicle to the business management server 160. In particular, the vehicle terminal 130 may be installed in the vehicle 110 and when the vehicle 110 is positioned in a tollgate, a government office, an inspection office, a mart, a park, and the like, the vehicle terminal 130 transmits the vehicle information to the business management server 160 in real time via receivers.
The vehicle terminal 130 may be a high pass terminal and the vehicle terminal 130 includes an electronic card 150 having vehicle information. Further, the electronic card 150 may be a separate personal recognition apparatus. The vehicle information of the electronic card 150 is stored in the vehicle controller (not illustrated) of the vehicle. Further, the vehicle terminal 130 transmits the driving information, and the like, generated from the vehicle to the business management server 160 through a receiver 140, and the like.

The vehicle information is a security code for protecting personal information. The vehicle identification number and the vehicle controller data number are generated and stored at the time of manufacturing the vehicle. Further, the vehicle terminal information may include high pass information. In particular, the vehicle terminal 130 may be the authenticated high pass terminal.
Further, the vehicle controller 210 primarily confirms matchability of the stored vehicle information of the vehicle terminal 130 whenever the vehicle 110 starts.
Further, the vehicle information is also transmitted to the vehicle management server 120 (FIG. 1) and the vehicle management server 120 (FIG. 1), and the business management server secondarily confirms the matchability of the vehicle information. That is, the matchability of the vehicle information is confirmed doubly. When any one of the primary matchability and the secondary matchability does not coincide with the vehicle information, the economic driving evaluation information is reset. The economic driving evaluation information may be, a discount rate applied to a grade, a toll, and the like.
The driving manipulator 230 has a handle, a start key, an accelerator pedal, a brake pedal, a gear transmission, and the like.

A vehicle detector 303 collects traffic information, and a driver display 304 displays toll cost and the like to a driver.
FIG. 4 is a diagram for guiding economic driving according to the system for guiding economic driving illustrated in FIG. 1. Referring to FIG. 4, when driving information 401 is generated, the vehicle controller 210 transmits the generated driving information 401 to the business management server 160 through the vehicle terminal 130.
Further, the vehicle information, the driver information, and the like are transmitted to the vehicle management server 120 through the TMU 240 or a general scan tool (GST) 430. Additionally, the vehicle information, the driver information, and the like are transmitted to the business management server 160 through the vehicle terminal 130.
The GST 430 is used in the case in which there is no TMU. In the case of the communication between the vehicle server 120 and the TMU 240, an Internet wireless communication network may be used and in the case of the communication between the GST 430 and the vehicle management server 120, the Intranet may be used.
For the communication between the business management server 160 and the vehicle terminal 130, a high pass receiver 441 or an information receiver 442 are used. In particular, the information receiver 442 is installed at places, such as a government office, a regular inspection shop, a mart, a park, and the like, which may automatically recognize a vehicle number.
For the communication between the vehicle terminal 130 and the receiver 140, near field communication such as radio frequency identification (RFID) and BLUETOOTH may be used.
The business management server 160 interlocks with the vehicle management server 120 to compare the vehicle information, the driver information, and the like, to generate the economic driving evaluation information depending on the driving information, and to authenticate the information and provide the information to the driver 410. The economic driving evaluation information may also be provided through home page of a business and may also be provided on/off line at the time of visiting a management business for repairing. Therefore, the driver may share the economic driving information and the vehicle management server 120 and/or the business management server 160 may also provide the economic driving method.
FIG. 5 is a flow chart illustrating a process of guiding economic driving according to the exemplary of the present inventive concept. Referring to FIG. 5, the vehicle 110 (FIG. 1) generates and stores the vehicle information and/or the driver information and transmits the information to the vehicle management server 120 (FIG. 1).
Therefore, the vehicle management server 120 receives and stores the vehicle information and the driver information from the vehicle 110 and determines matching of the vehicle information whenever the vehicle starts (steps S510 and S511). In other words, whenever the vehicle 110 starts, the matchability of the vehicle information between the vehicle terminal 130 and the vehicle controller 210 (FIG. 2) is primarily confirmed and the matchability of the vehicle information between the vehicle management server 120, and the business management server 160 is secondarily confirmed. When any one of them is not matched (that is, same) between the stored information, the error is generated and reset (steps S512 and S541).
In step S511, when the matchability between the stored vehicle information is recognized, the vehicle controller 210 generates and stores the driving information depending on the driving and determines the matchability of the driving information (steps S520, S530, and S540). In other words, it is determined whether the driving information is the driving information which may not emerge from the real driving condition which is a matchability condition by diagnosing a change trend of the driving information.
As a determination result, when the driving information satisfies the matchability condition, the vehicle controller 210 transmits the driving information to the business management server 160, and the business management server 160 uses the driving information to generate the economic driving evaluation information depending on a preset economic driving algorithm (steps S550 and S560).
In step S540, when the driving information does not satisfy the matchability condition, the vehicle controller 210 resets the current driving information and repeatedly performs steps S510 to S540.
According to the exemplary embodiments of the present inventive concept, it is possible to allow car makers and public institutions to jointly manage the fuel efficiency driving data of the driver and performing the reward (for example, charge saving like discount of a high pass for commuting) therefor, thereby guiding the driver the fuel efficiency operation.
Further, it is possible to allow the engine control unit (ECU) to store the fuel consumption information for himself/herself and use regulations (for example, discount of toll, vehicle tax, insurance, and the like) for fuel driving by associating the fuel consumption information with the high pass for the vehicle and the communication system of the tollgate, the smart phone, or the system of the car maker itself.
The foregoing exemplary embodiments are only examples to allow a person having ordinary skill in the art to which the present inventive concept pertains (hereinafter, referred to as “those skilled in the art”) to easily practice the present disclosure. Accordingly, the present inventive concept is not limited to the foregoing exemplary embodiments and the accompanying drawings, and therefore, a scope of the present inventive concept is not limited to the foregoing exemplary embodiments.
