3 and 4 are diagrams for explaining a process in which a terminal having the configuration as described above collects vehicle occupant information and provides a service using the same according to the present invention.

When another device approaches a preset area range and a signal is received, the controller 140 of the terminal 100 discovers the other device 200 through the interface unit 180 (S310) and communicates with the other device 200. Perform the connection (S320).

To this end, the control unit 140 of the terminal 100 detects a signal transmitted from another device through the interface unit 180 and accordingly transmits and receives a message including information for connecting with the other device 200.

In this case, the device 200 is not limited to a specific communication terminal, and includes all electronic devices that support a wireless communication protocol and are user portable.

Referring to FIG. 4, when the other device 200 can communicate with, for example, a Bluetooth method, the controller 180 transmits a request message (Inquiry) through the interface unit 180 (S311) and sends a response message thereto. After receiving (S313), a communication connection is made by performing a paging process based on the information exchanged with each other.

In this case, the terminal 100 presets a transmission and reception range of the signal through the interface unit 180 in accordance with the size of the host vehicle, for example, by setting the preset distance to about 3m and attempts to connect only to a device capable of boarding the host vehicle. Waste of communication resources due to transmission and reception and connection attempts can be prevented.

When the other device adopts, for example, an Adhoc On-demand Distance Vector (AODV) routing protocol, the controller 140 transmits a route request message RREQ to communicate with the other device 200 (S311). As a response to this, after receiving the path response message RREP (S313), a communication connection is made based on information exchanged with each other.

According to the above-described Bluetooth scheme, in order to maintain communication between the terminal 100 and the device 200, frequency hopping synchronization, that is, the frequency channel between the two devices should be changed in the same manner. The above-described request and paging are processes for performing such frequency hopping synchronization, and thus, a connection is made between the terminal 100 and the device.

In the Inquiry process, the terminal 100 changes a channel in an Inquiry Hopping Sequence and repeatedly transmits an Inquiry packet. Accordingly, the device 200 checks whether an inquiry packet is received for a predetermined time by selecting one of the same 32 frequency channels, and when the predetermined time elapses, the device 200 repeatedly changes the received frequency channel to another channel among 32. Attempt to receive.

Subsequently, if the transmission frequency channel of the terminal 100 and the reception frequency channel of the device 200 match, the device 200 may receive an inquiry packet, and in response thereto, the device 200 may receive its own address (Bluetooth device address). ) And a clock (clock) to the terminal 100 and the paging (paging) process is performed by the terminal 100 notifies the device 200 of its own address (Bluetooth device address) and the clock (clock).

Meanwhile, the AODV routing protocol is a routing protocol that is routed according to the needs of the source node. The source node sends a route request (RREQ) to the neighboring node in a broadcast manner for route discovery, and the neighboring nodes are sent back to the neighbors. Broadcast the RREQ message to find the route to the destination.

Intermediate nodes that receive the RREQ message identify the sequence number to prevent loops from the message and store the reverse path. The destination node receiving the RREQ message transmits a Route Response (RREP) message in a unicast manner through the reverse path. The route forwarded to the destination node by the route through which the RREP is forwarded is stored. Accordingly, the source node receiving the RREP may transmit data to the destination node.

As described above, the device 200 responds to the communication connection request of the terminal 100 by way of example, but the order thereof is not fixed and the terminal 100 responds according to the request of the device 200. It may be performed.

When a communication connection with the device 200 is made, the controller 100 checks whether the device 200 is in a vehicle (S330).

To this end, the controller 100 checks the distance from the terminal 100 with reference to the location of the device 200 or compares it with a list of occupants of surrounding vehicles obtained through communication with surrounding vehicles. May decide whether to board a vehicle or to own vehicle.

In addition, if the device enters within the range of the set distance range, that is, determined by the size of the vehicle, for example, for a predetermined time, for example, 5 minutes, for example, when the length of the vehicle body is 3, within the region set to 3m. It may be determined that the device has boarded the host vehicle.

For example, when the host vehicle stops and the device enters into the own vehicle zone, the device is connected to the device, but if the device is within the zone of the own vehicle even after the host vehicle starts and reaches a certain speed or takes a certain time or more, Can decide to board the car.

The above-mentioned occupant identification methods may be used separately, or may be used in combination with other methods.

When it is determined that the device 200 is in the own vehicle, the controller 140 requests user information from the diabis 200 (S340).

The requested user information may include, for example, a user's name, age, gender, telephone number, insurance company, an emergency reception number to which the user wants to contact in case of an emergency.

The controller 140 receives user information requested from the device 200 through the interface unit 180 and registers user information of the device 200 as passenger information (S350). Of course, if the user of the device 200 does not want to register the user information, the device 200 does not allow communication with the interface unit 180 of the terminal 100 or registration of the user information through the above-described process. It can be set in advance.

On the other hand, if the device 200 does not support a wireless protocol that can communicate with the interface unit 180 of the terminal 100, the user of the device 200 directly through the device 200, for example, the terminal 100 by the CDMA method Connect with the communication module 150 of the) to inform the boarding and to register the user information or to directly register the user information through the input unit 130 of the terminal 100. In this case, it is preferable to display an identification number for communication connection with the terminal 100 such as, for example, a telephone number of the terminal 100.

The controller 140 determines whether the device 200 leaves the area right of the host vehicle (S360).

To this end, the controller 140 may communicate with the device 200 periodically at a predetermined time interval through the interface unit 180 to check whether the device 200 leaves the area right of the vehicle.

Thus, for example, when communication with the device 200 is interrupted for a predetermined time, for example, 5 minutes or more, it may be determined that the device 200 has left the vehicle.

In addition, for example, when the speed of the host vehicle becomes '0' and the communication with the device 200 is interrupted after stopping, the device 200 attempts to communicate after the host vehicle starts again and the communication is disconnected because there is no response. It can be judged that the deviation occurred in.

On the other hand, if the device 200 does not support a wireless protocol for communicating with the terminal 100 and the user registers user information directly through the device 200 or through the input unit 130 of the terminal 100, the user himself The user of the device 200 may determine whether the user departs from his vehicle in a manner of releasing registration.

If it is determined that the device 200 has deviated from the host vehicle, the controller 140 deletes the device 200 user information from the occupant information list stored in the memory 120 to release the registration (S370).

Meanwhile, the controller 140 may request a service to be provided to the server 20 of the telematics center based on the information of the vehicle occupant including the vehicle driver. In this case, the controller 140 transmits the vehicle occupant information stored in the memory 120 to the server 20 through the communication module 150 to request a service.

In particular, when an emergency situation such as a vehicle accident occurs, the controller 140 transmits the accident situation and information of the vehicle occupant who is the accident party to the server 20 of the telematics center. Accordingly, the server 20 not only provides information for accident relief to the terminal 100, but also promptly and accurately rescues accidents and occupant information to related agencies such as police stations, insurance companies, car repair shops, and hospitals for accident relief. It can provide services for
