3 is a diagram for explaining operations of a map update apparatus and an external server according to an embodiment of the present invention.

When the map update apparatus 310 and the external server 330 transmit and receive data, the communication method is not limited and may be a communication network (for example, a mobile communication network, a wired Internet, a wireless Internet, , WAVE communication), as well as near-field wireless communication between devices. For example, the network 320 may be a personal area network (LAN), a local area network (LAN), a campus area network (CAN), a metropolitan area network (MAN), a wide area network (WAN) , A network such as the Internet, and the like. The network 320 may also include any one or more of a network topology including a bus network, a star network, a ring network, a mesh network, a star-bus network, a tree or a hierarchical network, It is not limited.

3, a process of transmitting and receiving data between the map updating device 310 and the external server 330 through WAVE communication will be described.

WAVE communication is to communicate dangerous situations that occur on the road ahead of the vehicle, such as expressway situation on high speed roads or general roads, through vehicles, vehicles and roadside bases, May refer to a communication system. For example, WAVE communication can be a great help to prevent traffic accidents such as forward danger detection, traffic traffic control, emergency vehicle crossing irregular passage, prevention of intersection crossing accident, and motorcycle approach detection.

In the embodiment, the WAVE communication causes the map updating device 310 installed in the vehicle to transmit the map information about the updated map to the external server 330 so that the external server 330 can transmit the map information and the additional information according to the map information After updating, it may be possible to provide updated information to each map update device 310.

The map update device can output route information according to the source and destination. Suppose that the vehicle 300 travels based on the route information according to the start point and the destination that are output to the map update device 310. [ The vehicle 300 can deviate from the route while moving on the basis of the route information. At this time, the map update device 310 can determine whether the vehicle is deviated from the route based on the route information. In other words, the map updating device 310 can determine whether or not the vehicle is deviated from the path by comparing the satellite-based position coordinate information for the current position with the respective running information for the black box image and the already stored path information .

The map update apparatus 310 can collect the travel information from the departure point as it is determined that the route has been departed. The map updating device 310 may collect driving information such as satellite-based position coordinate information, black-box image information, satellite photograph information, and base station information from the departure point and store the collected driving information in a separate storage space. For example, the map update device 310 may store the collected travel information in a local storage space, a memory, a cloud storage, or the like.

The map update device 310 can re-determine whether the travel information is included in the route information while collecting the travel information. At this time, the map updating device 310 can determine whether the traveling route is included in the route information displayed in real time or at predetermined time intervals.

If the travel information is not included in the route information, the map update device 310 may continuously collect and store the travel information from the departure point. When the travel information is included in the route information, the map update device 310 can store only the travel information that has been lost. The map updating device 310 can automatically update the map by storing the traveling information that has been lost. For example, the map updating device 310 can update the map by mapping the running information on the map.

After updating the map by storing the traveling information that the map updating device 310 has deviated from, the vehicle 300 can move the route based on the traveling information that was later departed again. At this time, the map update apparatus 310 may provide the map update apparatus 310 with a path based on the updated map.

The map update device 310 can transmit the map information to the external server 330 based on the WAVE communication. At this time, the map updating device 310 transmits the map information to the external server 330, so that the external server 330 transmits the satellite-based position coordinate information, the satellite photo information, and the WAVE base station information stored in the external server database The route information and the additional information from the departure point can be updated by comparing the running information that is currently being run based on at least one piece of information.

Thereafter, the external server 330 may transmit the updated map to each of the map update devices via WAVE communication.

4 is a flowchart illustrating a method of updating a map update apparatus according to an embodiment of the present invention.

At step 410, the map update device may determine whether the vehicle is traveling on the road. For example, the map update device can determine the location information based on the satellite-based position coordinate information. The map update device determines whether or not the current position is included in the route information based on the route information. At this time, if the current location is not included in the route information, the map update device can determine that the route is out of order.

In step 420, the map updating device may collect driving information from the departure point of the vehicle. The map updating device may collect at least one of driving information of satellite-based position coordinate information of the current driving route, the speed of the vehicle, the black box image, the satellite photograph, or the base station, and store the collected information in a separate storage space.

At step 430, the map update device may determine whether the vehicle has entered the road again. For example, in moving the route based on the route information, the vehicle may leave the route and then enter the route included in the route information again. At this time, when the map update device determines that the vehicle does not enter the road according to the route information, it can continuously collect the travel information.

In step 440, if the vehicle includes the traveling information included in the route information, the map updating device may update the traveling information of the section that has departed from the leaving point on the map. Alternatively, the map update device may update the map on the map from the departure point every predetermined time.

In step 450, the map updating device can transmit the map information according to the updated map to the external server based on the specific communication method. For example, the map updating device can transmit map information to an external server based on the WAVE communication method. Also, the map updating device can transmit only the updated map information to the external server, and can transmit the entire map information including the updated map information to the external server.

5 is a flowchart illustrating a method of updating map information transmitted from a map updating device in an external server according to an exemplary embodiment.

At step 510, the external server may receive map information from the map update device. At this time, the map information may refer to map information about the updated map in the map update device.

In step 520, the external server may compare the latest map information with information stored in the database. The external server 330 compares the information with the latest map information based on at least one of satellite-based position coordinate information, satellite picture information, and WAVE base station information stored in the database of the external server, The additional information can be updated.

In step 530, the external server may determine whether there is a portion that needs to be modified. In step 540, the external server may update the route information and the additional information with respect to the portion requiring modification. The external server can determine that there is a part to be corrected or a part to be added. For example, when the road is newly opened, the map information transmitted from the map update device may include new travel information. The external server can update by extracting new travel information and adding route information and additional information to the map.

In step 550, the external server may send the updated information to the map update device. The external server can deliver updated information to each of the map update devices.
