The present invention relates to a self-lubrication system, and more particularly, to a self-lubrication system using a toll electronic collection terminal mounted in a vehicle.

In modern society, automobiles are the main means of transportation for individuals, and their use is increasing continuously. Accordingly, various service industries for automobiles are expanding their business fields. Costs to be paid by modern people when driving a car include tolls for toll sections such as bridges and expressways, parking fees for the use of parking lots, and fueling for oil products, which are the energy source of automobiles.

Since the above-described costs for driving a vehicle are practically impossible for the driver of the vehicle to stop driving and come out of the vehicle to pay, the payment of the vehicle's driver's seat is inevitable and the payment is inconvenient.

In order to alleviate such inconveniences, various types of fee payment methods and systems using smart cards have been proposed and used in toll collection and parking fee collection. Paying directly by using a smart card with a smart chip equipped with a security means that can store the value of money in electronic form, communicates with the collection terminal in a contact or contactless manner, such as tolls and parking fees. Payment is made. In this case, since the collection terminal and the smart card held by the driver must be approached at a considerable close distance (within 10 cm), it is inconvenient to carry out payment in the driver's seat. In addition, when applied to expressway toll collection, since the speed of the vehicle should be reduced to almost a stop speed in order to access the smart card to the terminal for collecting, it becomes a factor that prevents smooth vehicle communication.

In order to improve the disadvantage, a method of performing long-distance communication between the OBU and the collection terminal while using a smart card that can communicate at a longer distance or by connecting a smart card to an on-board unit (OBU). This has been proposed.

Due to the problem of electromagnetic interference caused by stability of communication channel and large power transmission of collection terminal, dual electronic method is delayed commercialization, and the latter method, which can expect lower manufacturing price of OBU, is approaching more commercialization. have.

In this case, the driver may perform an operation instruction such as input of a fuel flow rate, using a user interface provided in the DSRC vehicle terminal 100 inside the vehicle, rather than using a user interface provided in the fueling device 400. It is desirable to. This allows the driver to give a fueling operation instruction using a familiar interface, thereby preventing a mistake in the fueling operation instruction process of the driver.

The subscription authentication module 350 is for checking the authenticity of the vehicle terminal 100 side, and may be a software module including a security algorithm such as 3DES or SEED and / or a security key for authentication. It may be an authentication hardware module (eg, smart chip, microcontroller) including an internal processor that performs the operation. The simplest implementation may be a white list, which is a set of identification codes of an available vehicle terminal (or smart card) or a black list, which is a set of identification codes of an unusable vehicle terminal (or smart card). On the other hand, in the case of sufficient security requirements only authentication for fueling payment, authentication for a separate vehicle terminal (or smart card) can be omitted, in which case the subscription authentication module 350 can be omitted.

In addition, in implementing the wireless refueling payment service according to the present invention, the implementation of confirming whether or not to subscribe to the service, whether the subscription terminal of the DSRC vehicle terminal 100 itself, and the authenticity authentication of the smart card 110; It is possible to implement as. The latter case is preferable from the point of view of providing integrated services to subscribers.

The control unit 320 controls the overall operation of the gas station server 300, and controls the fueling device 400 and the receipt issuing device 600, which is the equipment located in the gas station area geographically. The controller 320 issues an operation command to the fueling device 400 according to a driver's operation instruction, and when the fueling and payment is completed, the controller 320 controls the receipt issuing device 600 to issue a receipt.

As shown in FIG. 5, the self-lubrication method performed by the gas station server 300 may include: determining whether service is possible by authenticating a vehicle terminal requesting refueling or an independent storage medium connected thereto (S220 to S230); Transmitting fueling fee information to the vehicle terminal (S233); Step S237 of receiving a flow rate information input by a driver through the vehicle terminal; Performing lubrication corresponding to the lubrication amount (S240, S245); And electronically paying for fueling charges using an independent storage medium connected to the vehicle terminal (S250 to S265).
