The present invention relates to a navigation system, and in particular, it is possible to easily update the real-time traffic information and the new information of the map data, and to perform the route guidance reflecting this, and the remote person directly set the destination and the route of the user In addition, the present invention relates to a navigation system that enables a user to directly check a user's current location, driving path, and driving status from a remote location through information provided from the user's navigation device.

Navigation devices are rapidly increasing in number of users due to various reasons such as increase in vehicle ownership, increase in leisure activities, increase in new roads, and reasons for supplementing a lack of vehicle multimedia system. Such a conventional navigation device can implement various multimedia functions and additional functions in addition to the basic navigation functions such as route guidance and safe driving guidance, and can be used for various purposes, but limited use by some users due to the limitations in this regard. Only used as a situation. The conventional navigation device uses a touch screen as an input and output device, and includes a central processing unit, a memory, and a positioning device, and additionally includes a broadcast receiving device and an external interface. That is, the conventional navigation device is limited to its role as a navigation device and some multimedia players, despite the use of advanced technologies such as a touch screen for the convenience of operation while driving, and thus the improvement for convenient use for various purposes is limited. It is necessary.

One of the great reasons for the conventional navigation device to play a limited role is due to the closure of the device. In general, the conventional navigation device is weak in real time information transmission capability by repeatedly outputting and providing only the stored information other than the update. In addition, the navigation device for receiving a signal from the outside is limited to the reception of radio and DMB broadcast signals, and the user has to use a separate device for communication with the outside. In particular, this problem is due to the presence of excessive kinds of devices and maps due to the troublesome navigation manufacturers and electronic map makers, most of which are closed and incompatible with each other. Therefore, although the conventional navigation device is a device capable of implementing various functions, it is limited to a driver in a vehicle and plays only a limited role of providing route information.

In addition, such a conventional navigation device is frequently searched for a road, a building, a house number, etc. due to a manual update by a user, and in particular, a road such as a rural farm road is hardly represented. Therefore, when the user moves to such a non-display area, it is difficult to guide the route, and frequently the user leads to the wrong route. In addition, since the manual update is made by the user, there is no function of reflecting the real-time traffic information and setting the route through it. Although some navigation devices provide Transport Protocol Expert Group (TPEG) services for real-time traffic information, the TPEG information is provided to DMB broadcast channels to an unspecified number of users. There is an inconvenience of having to pay attention to the information.

In particular, as described above, when a specific destination is visited, a building designated by the other person is often not displayed on the navigation even when the user wants to navigate the road by another user who knows the destination or another person who lives in the destination. Therefore, in this case, the user is inconvenient to repeatedly contact another building several times with other buildings. In addition, there is no way for others who have described the route to check whether the user is proceeding with the normal route, and inconvenience such as frequently calling and confirming the driving user is caused.

In addition, in the conventional navigation device, various kinds of maps and devices exist and mutual compatibility between them is inconvenient, thereby causing another problem.

3 is an exemplary view for explaining a navigation system according to an embodiment of the present invention.

Referring to FIG. 3, the navigation system 100 according to the present invention has a function of accessing the navigation device 110 through an external terminal 190 so that a remote user can use the navigation device 110 similarly to a user. To provide. 3 is an exemplary view illustrating an example in which the route guidance and the map data mad output to the navigation device 110 are similarly output through the external terminal 190 as an example of such a function.

The navigation system 100 of the present invention can be divided into several functions according to the operation. For example, the navigation system 100 of the present invention can be divided into a navigation function for a user, a multimedia function, a service use function according to an external connection, and a function for a remote user. Here, the division of these functions is for the convenience and understanding of the description and thus does not limit the present invention.

First, the navigation system 100 of the present invention may provide a navigation function to a user through the navigation device 110. To this end, the navigation device 110 is driven by the user and outputs the map data mad stored in the storage device 119 through the output device 113. At this time, the navigation device 110 outputs the route from the route guidance data pgd according to the user's setting input (oin) input through the input device 115 and outputs the route, and performs voice guidance. Done. In such a navigation function, in addition to the above-described basic map data (mad) and route guidance, a function implemented in a conventional navigator device such as safe driving and an alarm may be implemented.

In addition, the navigation device 110 in the navigation system 100 of the present invention can provide various multimedia functions. The navigation apparatus 110 of the present invention also has a video display device and an audio display device as an output device 113 as in the conventional device, and includes a storage device 119. Therefore, it is possible to provide various multimedia functions to the user by storing various types of multimedia data, for example, MP3 files, AVI files, and image files in the storage device 119 and playing them using respective codecs or processing programs. Do. In addition, it is possible to additionally configure the radio broadcast receiving device or the DMB broadcast receiving device in the communication device 117 to receive and reproduce the external broadcast and provide it to the user. In addition, such a multimedia function can be implemented simultaneously with the implementation of the navigation function, it is also possible to increase the user's convenience through the PIP (Pictrue in picture), NIP (Navigation In Picture) functions.

Meanwhile, as described above, the navigation system 100 of the present invention is configured such that the navigation device 110 is connected to the outside by the data communication network 150. When the connection of the navigation device 110 is implemented through a wireless Internet service such as WiBro, it is possible to implement a constant connection to increase the convenience of the user and improve the multipurpose function of the navigation system 100. For the external connection of the navigation device 110, the connection between the navigation device 110 and the data communication network 150 is made through a wireless communication channel, so that the data communication network 150 relays the navigation device 110 and the heterogeneous communication network. It is desirable to. That is, the data communication network 150 may relay a heterogeneous network such as a wired telephone network and a mobile communication network and the navigation device 110 in addition to the Internet network so that a user may use various services in the vehicle through the navigation device 110. . As such, when the navigation device 110 is easily connected to the outside through the data communication network 150, various advantages occur. First, updating of map data mad becomes easy. That is, when the navigation device 110 is driven by the user, the navigation device 110 determines the current position of the navigation device 110 by using the location detecting device 111 and communicates with the communication device 117. As a result, a communication channel is formed with the data communication network 150, and the data communication network 150 is informed that communication is possible. Once formed in the communication channel, the user using the navigation device 110 checks the update information of the map data mad using a service provided through the data communication network 150 such as the Internet, and selects an update. It can be done. In addition, such an update process may be automatically performed by the navigation apparatus 110 or may be notified to the user that there is an update content, so that the update may be performed according to the user's selection. However, for such automatic update, the map data mad used for the navigation device 110 and its update data are managed through the data communication network 150 as described above with reference to FIG. 1, and the navigation device 110 is updated. The update server 160 should be configured to determine whether or not to provide update data. In addition, when the data communication network 150 forms a communication channel with the navigation device 110, it is possible to receive real-time traffic information and reflect the same in a route guide. In particular, the path of the user through a separate system configured to be connected to the update server 160 or the data communication network 150 as well as the Transport Protocol Expert Group (TPEG) provided to an unspecified number as in the prior art. It is possible to select only the information corresponding to and provide it to the designated user.

Meanwhile, the navigation device 110 connected to the outside by the data communication network 150 and the navigation system 100 including the same allow the remote user to access the navigation device 110 and share information (or data). . That is, a unique device ID (DID) is assigned to the navigation device 110 so that the user can access (or access) the navigation device 110 remotely through the data communication network 150 and thereby. It is possible to implement various types of functions. For example, when a user visits a remote user or wants to visit a place known by the remote user, the remote user controls the user's navigation device 110 with the user's permission without using a means such as a telephone. Route and destination information can be provided to the user. This process can be performed using the external terminal 190 that can be connected to the data communication network 150 as described above. In addition, when providing the map data (mad), the destination and route information (dpad), the route guidance data (pgd) from the user's navigation device 110 to the external terminal 190, the remote user knows where the user is and in what state Can be checked remotely. In addition, since the navigation device 110 and the external terminal 190 can be continuously connected through the data communication network 150, the communication channel is maintained between the user and the remote user through the communication network, thereby communicating. It becomes possible to proceed. That is, when the user receives the WiBro service, that is, the wireless Internet service through the data communication network 150, the user and the remote user can maintain the voice chat function in a continuous connection state. This enables the user to navigate the daily conversation as well as the directions from the remote user, the remote user can check the user's driving status in real time. In particular, in the case of maintaining a conversation state such as voice chat, in case of a traffic situation that is not reflected in the real-time traffic information, active information sharing may be made, such as being provided with a detour route by a remote user who knows the route well. In addition, in the case where the navigation apparatus 110 of the present invention is installed in each of a plurality of vehicles, it is easy to share information, confirm the position of each other, and move the group along the same path. In addition, in the case of extending these functions, it is possible for the remote user to recognize the driving position of the user by using the additional devices installed in the user's vehicle by checking the actual road environment. For example, if a vehicle has a small camera that can be connected to a camera or a navigation device 110 for parking detection, it can be used as the input device 115 of the navigation device 110, and the input device 115 can be used. By taking the driving situation, the user's situation can be provided to the remote user as a video data, the remote user can check the video data in real time to induce the user's safe driving. In addition, this function can be usefully used in the occurrence of emergency patients. That is, the navigation system 110 is connected to the hospital system, thereby real-time monitoring of the status of the user in the vehicle or emergency vehicle, and by taking appropriate measures for the patient by remotely directing the appropriate measures to the hospital It is possible to transfer to. In addition, the user may use various services such as an e-mail, an internet service, a text transmission, and an internet phone via the data communication network 150 through the navigation device 110.

In order to provide such an external access function, the navigation device 110 must perform the authorization for the external access and the user's permission process accordingly, and set the appropriate authority according to the user's specification to limit the functions available to the remote user. Or preferably enlarged. In addition, in addition to a navigation program and a multimedia playback program, a browser and other applications that can use a service such as the Internet may be included in the storage device 119 in order to use the service through the external access and the data communication network 150. It is stored and driven as needed.

The server 270 first delivers it. The navigation server 270, which has received the data, processes or modifies the provided data into a form suitable for an external terminal 290 or an external system, thereby transmitting various types of external systems or external terminals as compared to the first embodiment. The 290 can access the navigation device 210 as well as reduce the load on the navigation device 210. In particular, in the case of using the navigation system 200 of the present invention in the form of electronic commerce, it is possible to perform member management by the navigation server 270 and to perform billing according to the connection with the navigation device 210. In addition, it is possible to improve the security by performing the connection authentication by the navigation server 270 together with the navigation device 210. Furthermore, the navigation device 210 is continuously managed, and the real-time traffic information can be provided more accurately.

5 is a flow chart for explaining the implementation of the navigation system of the present invention.

Referring to FIG. 5, the service providing method of the navigation system according to the present invention includes a device driving step S100, a data updating step S20, a setting step S30, and a service providing step S40.

The device driving step S100 is a step in which the navigation devices 110 and 210 are driven according to the initial installation or the supply of power. In the device driving step S100, when the navigation devices 110 and 210 are powered and driven, the navigation devices 110 and 210 proceed to prepare for the operation of the navigation devices 110 and 210. When driven according to the power supply, the navigation device 110 or 210 drives the location detecting device 111 to receive a GPS signal and obtains location information of the navigation device 110 or 210 through the operation of another sensor. . Meanwhile, the navigation devices 110 and 210 form a communication channel with the data communication networks 150 and 250, and register the navigation devices 110 and 210 to the data communication networks 150 and 250. Through this, devices of the data communication network 150 and 250, for example, devices such as a DNS server, perform a registration process of the navigation devices 110 and 210. On the other hand, when the navigation server 270 is configured as in the second embodiment, the navigation device 210 transmits the device ID (DID) to the navigation server 270 to register. Through the data communication network (150, 250) registration process, the navigation device (110, 210) can be used in the data communication network (150, 250), the address used as a unique identification code for each device, for example, IP address and The same address or number is given, and then communication is performed with the outside.

In the data update step S20, a process of allowing a user to use the latest information is performed. Through this data update step (S20), the user can alleviate the inconvenience of updating through a separate terminal using a memory stick one by one, and provides the advantage of using the latest road information by continuously checking the contents of the update. . To this end, the data update step S20 is updated in a slightly different form with and without the map data mad. For example, when the map data mad is newly provided due to the first use of the navigation devices 110 and 210 and the map data mad stored down previously exists, the update is slightly different. Proceed. To this end, in the data update step S20, it is determined whether the map data mad and the route guidance data pgd exist in the storage device 119 of the navigation device 110 or 210 after driving the navigation device S100 ( S200). As a result of the determination, when the map data mad and the route guidance data pgd do not exist, the process of downloading the map data mad and the route guidance data pgd through the data communication networks 150 and 250 is performed. S320). On the other hand, if the map data (mad) and the route guidance data (pgd) is present, the navigation device (110, 210) for the map data (mad) and route guidance data (pgd) stored through the data communication network (150, 250) The update information retrieval step S313 for checking whether the update information exists is performed. If there is update information, the map data mad and the route guide data pgd stored in the storage device 119 are updated (S316). The data update step S20 is performed by the navigation apparatus 110 or 210 through the update server 160 or the navigation server 270. On the other hand, although not shown, it is also possible to notify the navigation device (110, 210) that there is a content to be updated from the navigation server 270 or the update server 160 and perform the update through it. As such, when the data update step S20 ends, the set step S30 proceeds.

The setting step S30 is a step in which an input for using a service and a remote user connection are performed. The setting step S30 is divided into a process in which a user directly adjusts his or her navigation apparatus 110 and 210 and a step in which the navigation apparatus 110 and 210 is remotely operated by a remote user. First, in the setting step (S30), the user manipulates the navigation device (110, 210) through the destination and route data creation and reflection step (S410) to set the desired path and destination, and thereafter the navigation device (110, 210) You will use the route guidance service of. On the other hand, the remote user can access the user's navigation device (110, 210) using the external terminal 190, 290 through the setting step (S30). To this end, the remote user attempts to access the device ID (DID) of the navigation device (110, 210) through the external terminal (190, 290). Accordingly, the access authentication process of the external terminals 190 and 290 is performed in the access authentication step (S423). This connection authentication is used to prevent an unspecified remote user from arbitrarily accessing the navigation device 110, 210. Such access authentication is preferably limited to external terminals 190 and 290 to which the user has been granted access, or to remote users who have provided passwords and IDs for access. The connection authentication process is terminated, and the remote user accesses the user's navigation apparatus 110 and 210 through the path information (pad) receiving and reflecting step (S425), and the navigation apparatus 110 through the external terminals 190 and 290. In addition to providing information to the user by providing a setting input (oin), etc. for adjusting the 210, the navigation device (110, 210), the route information (pad) and the setting input (oin) provided from the outside This is reflected in the route guidance data (pgd) and map data (mad).

The service providing step (S40) is a step in which the setting step (S30) proceeds and the user actually uses the navigation service. The service providing step S40 basically includes a location information application and route guidance step S500 and a driving information and route guidance data provision step S600. In the location information application and route guidance step S500, the navigation devices 110 and 210 provide the route guidance service to the user by reflecting the location information acquired in the aforementioned device driving step S100. In addition, when the remote user is connected through the external terminals 190 and 290 together, the driving information and the route guidance data pgd of the user are transferred to the external terminal through the step S600 of providing driving information and route guidance data. Is provided. In addition, while the service use continues, the navigation system 100 or 200 continuously provides information according to a user's input.
