1 is a configuration diagram of a vehicle recognition system according to an embodiment of the present invention. Referring to FIG. 1, the vehicle recognition system 1 may include an authentication server 100, a receiver 120, and an OBD (On-Board Diagnostics) terminal 140. The authentication server 100, the receiver 120, and the OBD terminal 140 shown in FIG. 1 are illustrative of components that can be controlled by the vehicle recognition system 1. As shown in FIG.

Each component of the vehicle recognition system 1 of Fig. 1 is generally connected via a network. A network refers to a connection structure in which information can be exchanged between nodes such as terminals and servers. An example of such a network is Wi-Fi, Bluetooth, Internet, LAN Network, wireless LAN, WAN, PAN, 3G, 4G, LTE, and the like.

The authentication server 100 may include a database storing OBD terminal information and customer information of a customer. The authentication server 100 may receive the information of the OBD terminal from the receiver 120 when the vehicle equipped with the OBD terminal 140 accesses the receiver 120. [ The authentication server 100 can authenticate the OBD terminal 140 based on the information of the OBD terminal received from the receiver 120 and the previously stored OBD terminal information of the customer and transmit the authentication result to the receiver 120. [ At this time, the information of the OBD terminal may include the unique number of the OBD terminal, the wireless MAC number, but is not limited thereto.

When the vehicle passes through the receiver 120, the authentication server 100 receives the customer information of the OBD terminal from the receiver 120, and authenticates the vehicle based on the received customer information and pre-stored customer information. At this time, the customer information may be, but is not limited to, a customer management number, a customer's telephone number, or a card number.

The receiver 120 may be installed at a location where it is configured to send and receive information between the authentication server 100 and the OBD terminal 140 and to determine whether the vehicle has entered and passed or whether the vehicle has entered and passed .

The receiver 120 may receive a connection attempt message containing the information of the OBD terminal from the OBD terminal 140 of the vehicle when the vehicle approaches the receiver 120. [ The receiver 120 may forward the OBD terminal information received from the OBD terminal 140 to the authentication server 100 and may receive the authentication result of the OBD terminal from the authentication server 100. [

The receiver 120 may receive a plurality of vehicle signals from the OBD terminal 140. For example, the receiver 120 may be configured to receive a vehicle signal a plurality of times sequentially as the vehicle equipped with the OBD terminal 140 approaches the receiver 120 and passes through the receiver 120 . At this time, the vehicle signal received from the OBD terminal may include, but is not limited to, vehicle type, steering direction, and vehicle speed.

The receiver 120 can measure the speed variation of the vehicle based on the vehicle speed received from the OBD terminal and measure the RSSI (Received Signal Strength Indication) intensity based on the received vehicle signal. The receiver 120 can determine the entry or the passing of the vehicle on the basis of the direction of the steering wheel received from the OBD terminal 140, the speed variation of the vehicle measured by the receiver 120, or the RSSI intensity, It is possible to reduce errors that may occur when judging entry and passage.

The receiver 120 may determine the entry and passage of the vehicle based on the RSSI strength. For example, the RSSI strength of a plurality of sequentially received vehicle signals is measured. If the RSSI intensity is high, it is determined that the vehicle is entering the receiver 120. If the RSSI intensity is small, the vehicle passes through the receiver 120 .

The receiver 120 notifies the authentication server 100 that the vehicle has entered the receiver 120 and informs the authentication server 100 of the fact that the vehicle is passing through the receiver 120. [ Pass information, and transmit the customer information to the authentication server simultaneously or sequentially.

The receiver 120 may include a first receiver and a second receiver with a narrower signal reception area than the first receiver, but is not limited thereto. It is also possible to further include a third receiver. It is possible to more accurately determine the degree of entry of the vehicle by installing a plurality of receivers having different reception regions of the signals. For example, if the first receiver receives a vehicle signal from the OBD terminal 140 attached to the vehicle but the second receiver with a narrower signal reception area than the first receiver does not receive the vehicle signal, It can be judged that it is approaching near the receiver but has not entered yet.

The OBD terminal 140 may be mounted in the vehicle and may transmit a connection attempt message including information of the OBD terminal to the receiver 120 when the vehicle approaches the receiver 120. [ The OBD terminal 140 receives a vehicle signal request from the receiver 120 until the vehicle passes through the receiver 120 from when the vehicle approaches the receiver 120 and transmits the vehicle signal to the receiver 120 in response thereto . The OBD terminal 140 may receive the customer information request from the receiver 120 when the vehicle passes through the receiver 120 and may transmit the customer information to the receiver 120 in response.

The OBD terminal 140 can communicate with the receiver 120 using wireless communication of the terminal itself, for example, WiFi or Bluetooth, but the communication method is not limited thereto.

2 is a view for explaining an entry process of a receiver and an OBD-equipped vehicle according to an embodiment of the present invention. Referring to FIG. 2, when the vehicle equipped with the OBD terminal enters the signal receiving area of the first receiver, the OBD terminal transmits a connection attempt message to the receiver, and the receiver can determine that the vehicle has approached the receiver. The RSSI intensity of the vehicle signal begins to become smaller as it approaches the receiver and then decreases as it passes through the receiver. Thus, the receiver can determine that the vehicle has entered the receiver when the RSSI intensity of the receiving vehicle signal is high, and can determine that the vehicle has passed the receiver when the RSSI intensity of the receiving vehicle signal is small.

3 is a diagram for explaining a series of processes performed in the vehicle recognition system according to an embodiment of the present invention. Referring to FIG. 3, when the vehicle equipped with the OBD terminal accesses the receiver, the OBD terminal transmits an access signal message including the information of the OBD terminal to the receiver. The receiver transmits the information of the OBD terminal to the authentication server, and the authentication server authenticates the OBD terminal based on the information of the OBD terminal. Thereafter, the OBD terminal transmits a vehicle signal in response to the vehicle signal request of the receiver, and the receiver informs the authentication server of the entry of the vehicle when it is determined that the vehicle has entered the receiver. Thereafter, the OBD terminal transmits the vehicle signal in response to the vehicle signal request of the receiver, and when the receiver determines that the vehicle has passed the receiver, the OBD terminal receives the customer information from the OBD terminal and transmits the customer information together with the vehicle passing notification to the authentication server . The authentication server authenticates the vehicle based on the received customer information.
