The output unit 140 is for generating an output related to visual or auditory information, and may include a display unit 141 and an audio output unit 143.

The display unit 141 displays information processed by the telematics terminal 100. For example, when the telematics terminal 100 is navigating the route, a UI (User Interface) or GUI (Graphic User Interface) associated with route guidance is displayed.

The display unit 141 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display ), A three-dimensional display (3D display), and the like.

When the display unit 141 and the sensor for sensing the touch operation form a mutual layer structure, the display unit 141 can be used as an input device in addition to the output device.

The audio output unit 143 can output audio data received from the communication unit 110 or stored in the memory 150. [ The sound output unit 143 outputs an acoustic signal related to a function (e.g., route guidance) performed by the telematics terminal 100. [ The sound output unit 143 may include a receiver, a speaker, a buzzer, and the like.

The memory 150 may store a program for the operation of the controller 160 and temporarily store input / output data (e.g., still images, moving pictures, etc.). In addition, the memory 150 may store map data for route guidance.

The memory 150 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (e.g., SD or XD memory) At least one of a random access memory (RAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM) Type storage medium.

The controller 160 may control the overall operation of the telematics terminal 100 and may be implemented by one or more microprocessors operating according to a set program. The set program may be implemented by a traffic information providing method according to an embodiment of the present invention And a series of commands for performing each step included in the command.

The telematics terminal 100 according to the embodiment of the present invention may further include a camera 170. [ The camera 170 processes image frames such as still images or moving images obtained by the image sensor in the photographing mode. The image frame processed by the camera 170 may be stored in the memory 150 or transmitted to the outside through the communication unit 110. [ The camera 170 may be a black box camera provided in the vehicle 1. [

As shown in FIG. 1, the telematics server 200 includes a data transmission / reception server 210, a database server 220, and a control server 230. When such components are implemented in practical applications, two or more components may be combined into one component, or one component may be divided into two or more components as necessary.

The data transmission / reception server 210 receives information provided from a plurality of telematics terminals 100 through a network. Also, the traffic information provided from the control server 230 is transmitted to the telematics terminal 100 through the network.

The database server 220 includes a node information database 221 and an image database 223.

An identifier (ID) is assigned to each node in the node information database 221, and position information on the node is stored. In addition, the node information database 221 stores the number of times the route departure event is generated for each node. In the case of a node in which a path exit event occurs more than a set value during the set period, it is stored as a rout path departure node.

In the image database 223, an image corresponding to the frequent departure route node is stored. For example, the image may be a still image or a moving image. If the image is a still image, it may include a background image around the desert route out-of-route node, a POI (point of interest) image, and the like. If the image is a moving image, it may include a moving image via the steady-state path releasing node.

The control server 230 generates traffic information based on the information received from the data transmission / reception server 210 and the information stored in the database server 220, and provides the generated traffic information to the telematics terminal 100. The control server 230 transmits the image corresponding to the desert route out-of-order node to the telematics terminal 100 through the data transmission / reception server 210 when the desert route out-of-order node exists on the desired route received from the telematics terminal 100 Lt; / RTI >

Hereinafter, a traffic information providing method according to an embodiment of the present invention will be described in detail with reference to FIG. 3 to FIG.

FIG. 3 is a flowchart of a method for setting a departure node from a telematics server according to an embodiment of the present invention.

Referring to FIG. 3, when the driver selects a destination through the user input unit 130, the controller 160 sets a desired path from the current position of the vehicle to the destination (S110).

The control unit 160 determines whether an out-of-route event occurs in which the vehicle leaves the desired route while driving (S120). For example, the control unit 160 may determine that a path departure event has occurred when the current position of the vehicle is a link other than the link on the desired route.

If the path departure event occurs, the control unit 160 transmits information on the node where the path departure event is generated to the data transmission / reception server 210 through the communication unit 110 (S130). The information on the node where the path departure event is generated may include coordinate information of the node.

The control server 230 stores information on the node where the out-of-path event has occurred in the node information database 221 and counts the number of times the event of the corresponding node is generated (S140). That is, the number of event occurrences of the node is accumulated based on the information on the out-of-path event received from the plurality of telematics terminals.

The control server 230 compares the number of events occurring during the set period of the node with the set value (S150). The setting period and the setting value may be set to a value that a person skilled in the art determines to be preferable in consideration of traffic volume information of the node, traffic accident information, information on the frequency with which the route passing through the node is set, and the like. For example, if it is determined that a vehicle passing through any node has a capacity of 200,000 vehicles per day and a vehicle corresponding to 20% sets a route, the set time may be set to 24 hours, and the set value may be set to 10,000.

If the number of events occurring during the setting period of the corresponding node is equal to or greater than the set value, the control server 230 sets the corresponding node as a normal path departure node (S160). The information on the set routines that are out of the path is stored in the node information database 221.

The control server 230 collects an image corresponding to the normal path departure node (S170). For example, the control server 230 may collect driving videos photographed by the camera 170 through a plurality of telematics terminals for which a desired route is set via the desert route deviation node, May be stored in the database 223. The collected moving images can be classified and stored according to time zones. For example, classified into daytime or nighttime.

4 is a flowchart of a traffic information providing method according to an embodiment of the present invention.

Referring to FIG. 4, the controller 160 receives the information about the departure route from the telematics server 200 through the communication unit 110 (S200). The information about the out-of-service path out-of-node may include an identifier, coordinate information, and the like corresponding to the out-of-service path out-of-node, and may be stored in the memory 150. The control unit 160 may map the information on the out-of-service path departing node to the map data and display the map data on the display unit 141.

When the driver selects a destination through the user input unit 130, the controller 160 sets a desired path from the current position of the vehicle to the destination (S210). At this time, the controller 160 may calculate one or more routes from the current position to the destination, and the driver may select the desired route among the one or more routes. Steps S200 and S210 may be performed independently or simultaneously.

The control unit 160 determines whether there is a rout path departure node on the desired path (S220).

If it is determined in step S220 that the desert route non-departure node does not exist on the desired route, the controller 160 terminates the traffic guidance method according to the embodiment of the present invention and performs the normal route guidance.

If it is determined in step S220 that the desert route missing node exists on the desired path, the controller 160 determines whether the image display condition is satisfied (S230).

For example, the image display condition may be satisfied when a driver requests an image corresponding to a desert route out-of-order node through the user input unit 130. [ That is, the control unit 160 may inform the driver through the output unit 140 that the desert route out-of-order node exists on the desired route (S231). The control unit 160 requests the telematics server 200 through the communication unit 110 for an image corresponding to the route for departing from the routine (S233). The control unit 160 receives the image corresponding to the out-of-service path departing node from the telematics server 200 through the communication unit 110 (S235). At this time, the received image may be an image corresponding to the current time zone. Accordingly, the driver can correctly recognize the departure-avoidance node regardless of the day or night, by viewing the image corresponding to the current time.

The control unit 160 may display an image corresponding to the normal route out-of-route node through the display unit 141 (S240). The driver can confirm the traveling movie in advance if there is a normal route departure node after setting the desired route. Therefore, it is possible to prevent the vehicle from deviating from the path.

In addition, the image display condition may be satisfied when the current position of the vehicle is within a predetermined distance from the wet / pass path departure node. That is, when the vehicle approaches the desert route out-of-route node, the control unit 160 can inform the driver through the output unit 140 that the desert route out-of-route node exists on the desired route.

As described above, according to the embodiment of the present invention, it is possible to identify a node where a path deviation event occurs regularly.

In addition, when the route passing through the normal route departure node is set, the image corresponding to the normal route departure node may be provided to prevent the vehicle from departing from the route.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.
