Navigation, system having the same and method of controlling the same {Navigation and system having the same and method controlling the same}

The present invention relates to a navigation system, a system having the same, and a control method thereof, and more particularly, to a navigation system for guiding a user to a destination in an optimal path, a system having the same, and a method of controlling the same.

In general, navigation measures the current position by using a GPS (Global Positioning System), and searches the route from the measured current position to the destination input by the user according to a preset route search method, It guides you to the destination along the searched route.

In general, a route search method includes a method of using 'national road priority', 'highway priority' and 'shortest distance', and a method of setting a path by reflecting traffic information. Here, the route priority, highway priority, and shortest route search methods are selected by route type and total distance, and the route search method using traffic information is provided by a service provider providing traffic information. Receives traffic information wirelessly and analyzes the received traffic information to search for and select the desired route, and the route search method using traffic information depends on the state of the road such as the driver of the road, traffic regulation, etc. How to navigate and select a route.

Such route search methods such as 'national priority', 'highway priority', and 'shortest distance' can not avoid a delay or congestion because the route is selected by the road type and the total distance. In other words, when searching for a route from the same location to the same destination at any time and in any situation, the same route is searched. Sometimes it takes more time to get to your destination without telling you.

In addition, the route search method using traffic information is a method of selecting a route in consideration of a road driver, a traffic regulation, etc., but there is an advantage of searching a route bypassing a delayed or congested section, but a separate traffic information receiver should be provided. As a result, the purchase cost is high.

The present invention is to solve the above problems, an object of the present invention is to receive the path search value of at least one road input from the user to search the path using the path search value of the road received by the actual use value of the road The present invention provides a navigation system for searching a route, a system having the same, and a control method thereof.

It is another object of the present invention to provide a navigation system for guiding a user to a destination on a route searched by taking into consideration the actual usage value of each road by sharing a route search value of each road among users through an information providing server, and a system having the same; It provides a control method.

Navigation according to the present invention for achieving the above object is a storage unit for storing a path search value corresponding to each of a plurality of roads that are path search conditions; An input unit configured to receive a route search value of at least one road among a plurality of roads from a user; a controller configured to update the route search value of the corresponding road stored in the storage unit with the input route search value of the input unit.

The navigation system according to the present invention includes a server for receiving and storing a route search value of at least one road changed by a user; It includes navigation to search the route by updating the pre-stored route search value of the at least one road with the route search value transmitted from the server and applying the updated route search value when the destination is set by the user.

The control method of the navigation system according to the present invention checks whether a route search value of at least one road, which is a route search condition, is input from the user, and if the route search value of at least one road is input, the route search value of the corresponding road is stored in advance. Update the entered route search value.

When the destination is set by the user, the method further includes controlling the route search by applying the updated route search value of the road.

The method may further include accessing a server providing route search values corresponding to the plurality of roads updated by the plurality of users, and receiving route search values of at least one road from the server.

Receiving the route search value of at least one road from the server further determines whether at least one area is selected by the user and, if at least one area is selected, receives the route search value of the road existing in the area. Include.

According to the present invention, the user can directly input the route search value corresponding to the actual use value of the road, and can search for the optimal route because the route is searched by using it according to the destination when searching for the next route. have. In addition, users can share the route search values of the road among users by uploading the route search values of each road to the server. That is, users are provided with a route search value of each road by accessing a server, and the route search value of the road is used in the route search so that the user can move to the optimal route to the destination.

As such, when the user sets the destination and moves to the destination along the searched route, the user may move to avoid a bad road, thereby saving the travel time to the destination and the fuel consumed by the vehicle.

Hereinafter, with reference to the accompanying drawings a preferred embodiment according to the present invention will be described in detail.

1 is a configuration diagram of a navigation system according to an embodiment of the present invention, which includes a navigation 100 and an information providing server 200.

The navigation apparatus 100 includes an input unit 110, a GPS unit 120, a controller 130, a display unit 140, a storage unit 150, a map information database 160, and an interface 170.

The input unit 110 includes a plurality of buttons for the user to control the operation of the navigation, and transmits the button data for the button selected by the user to the controller 130. That is, the input unit 110 receives destination information from the user and transmits the input destination information to the controller 130. In addition, the input unit 110 includes a route search value change button of a road for changing a route search value of a road, and after the user selects a route search value change button of a road, any one road is selected and the When the route search value is input, road information and a value corresponding to the selected road are transmitted to the controller 130.

Here, the route search value is a value for each road that becomes a route search condition for searching a route when searching for a route from a current location to a destination. That is, the route search value is stored in advance according to the type of the road when the navigation is manufactured, and the route search value can be changed by the user.

Here, the selection of any one road is selected by any one of inputting a road name of the corresponding road, inputting a longitude and latitude coordinate of the corresponding road, or touching and touching a road displayed on the display unit 140.

Global Positioning System (GPS) 120 receives each position signal from a plurality of GPS satellites, calculates its own position, and controls its calculated position when its position is calculated. Transmit to 130. The GPS unit 120 may include a GPS antenna ANT for receiving satellite signals from a plurality of GPS satellites, an acceleration sensor (not shown) for measuring the acceleration of the vehicle, and a direction sensor (not shown) for detecting the direction of the vehicle. The GPS unit 120 transmits the acceleration data and the direction data together with the current position of the vehicle to the controller 130.

 When the destination information is transmitted from the input unit 110, the controller 130 searches for a route from the current location to the destination, maps the searched route to map data, and then displays the map matching data and displays the route from the current location to the destination. To guide.

In more detail, when the destination information is transmitted, the controller 130 searches for a plurality of paths by combining a plurality of roads between destinations at the current location and calculates a cost of the found plurality of paths. Here, the cost is calculated by applying the path search conditions such as the road number (that is, the path search value), the road length, the number of traffic lights, and other resistance elements of the roads forming one path. The controller 130 searches for a path having the lowest cost among the plurality of paths, and guides the current path from the current location to the destination along the searched path.

When the road information and the route search value of the road are transmitted from the input unit 110, the controller 130 changes the pre-stored value of the corresponding road to the value transmitted from the input unit 110 to the storage unit 150. It is stored, and the route search value of the changed road can be applied during the route search. In addition, there are high speed national roads, general national roads, local roads, and sega roads. In the case of high speed national roads, the lowest values are assigned and stored, and in the case of Sega, the highest values are stored and stored.

In other words, if one road is Segado but the Sotoing is smooth, the value of Segado is lower than the pre-stored value, which increases the probability that the road will be searched when searching for a route, and thus increases the possibility of passing through the road. Even though the road is a national road, if the road is severely congested, the value of the national road can be changed higher than the pre-stored value to lower the probability of being searched when searching for a route than other surrounding roads.

The display unit 140 displays a map, an operation state, and additional information in which the current location of the vehicle is matched according to the instruction of the controller 130. The display unit 140 is a liquid crystal display (LCD) or a touch screen, and the like, in the case of a touch screen, displays a plurality of buttons for controlling the operation of the navigation, and any button among the displayed buttons. Alternatively, when the road on the map is touched, the position value of the touched part is transmitted to the controller 130.

The storage unit 150 stores a control program for controlling the operation of the navigation system, stores information about the searched routes, and numerical values corresponding to a plurality of roads, respectively. When the route search value of the road is transmitted, the route search value of the corresponding road is changed to the transmitted value and stored.

The map information database 160 stores map data having information on roads, road names and lane information, and points of change of roads, which are matched according to latitude and longitude, of nationwide terrains and terrains. Here, the change point of the road means a point such as a point where a lane changes on a certain road and an intersection.

The interface 170 is connected to a user terminal (not shown) to receive various information such as upgrade information of programs and map data related to the navigation system, route search numerical information of each road, and the like from the user terminal.

Here, the user terminal is a device capable of wired and wireless communication such as a PC, and is connected to the interface 170 of the navigation apparatus 100 to receive information provided from the information providing server 200, that is, a route search value of a road, and update existing data. can do.

The information providing server 200 receives and stores a route search value of each road from a plurality of users, and provides the requested information, that is, a road number when information is requested from a user terminal. In this case, when the request for providing the route search value of at least one area is requested from the user terminal, the information providing server 200 may extract only the route search value of the road in the corresponding area and transmit it to the user terminal.

2 is a flowchart illustrating a control of a navigation system according to an exemplary embodiment of the present invention with reference to FIGS. 1 and 3.

When the user operates the navigation 100, the position of the vehicle is received through the GPS unit 120, and the information matching the position of the vehicle and the map data is displayed through the display unit 140.

In this state, if the user wants to change the route search value of at least one road, the user selects (401) a road value change button provided in the input unit 110 and inputs at least one road information to select at least one road ( After inputting the route search value of the corresponding road.

When the road information and the route search value of the road are input by the user, the navigation apparatus 100 searches for a corresponding road based on the input information of the road and changes the searched route search value of the road to the value input from the user. To store (403). In this case, the road information is a road name of the road or a longitude coordinate of the road.

In addition, the navigation apparatus 100 communicates with the information providing server 200 or communicates with the information providing server 200 in a state of being connected to a user terminal (not shown). It is also possible to receive the route search value and change the pre-stored value of the corresponding road to the route search value of the road provided from the information providing server 200 and to store it. Here, the navigation 100 may be selected and provided for each region when receiving the route search value of the road from the information providing server 200.

In this way, users can share road numbers between users by uploading the route search values of each road to the information providing server 200. That is, when the users access the information providing server 200 and are provided with the route search value of each road, the user can move to the optimal route to the destination based on the route search value of the road.

When the route search value of at least one road among the plurality of roads stored in the map information database 160 of the navigation apparatus 100 is changed and stored in the storage unit 150, a destination is input from the user and is set 404. Search for a route from the current location to the destination.

In the path search, a plurality of paths are searched 405 by combining a plurality of roads from a current location to a destination, and the costs of the searched plurality of paths are respectively calculated 406. The cost is calculated by applying the path search value, the road length, the number of traffic lights, and other resistance elements of at least one road constituting each path.

The path corresponding to the minimum cost among the costs of the plurality of paths is searched (407). At this time, the searched route becomes the optimal route and the user is guided to the destination 408 while displaying the route on the display unit 140.

If the road environment of the road currently passing by the user is determined to be optimal due to the smooth communication while moving to the destination along the searched route, the user selects the corresponding road displayed on the display unit 140 and calculates the route search value of the road. It is possible to enter a value lower than the path search value of the pre-stored road. At this time, the navigation apparatus 100 stores the numerical value corresponding to the information of the road selected by the user as a newly input numerical value.

If the road environment of the road that the user is currently passing through is severe and is determined to be a bad road, the user selects the corresponding road displayed on the display unit 140 and compares the path search value of the road with the path search value of the previously stored road. Enter a higher value. At this time, the navigation apparatus 100 stores the numerical value corresponding to the information of the road selected by the user as a newly input numerical value. The route search value of the road input and changed by the user is used when searching for a route when the destination is set by the user.

In this way, the user can directly input the route search value corresponding to the actual use value of the road, and the route can be searched by applying the same when the route is searched, thereby finding the optimal route.

In addition, when the navigation system 100 operates without setting a destination, if the road environment of the road currently passing by the user is determined to be smooth and optimal, the user selects the corresponding road displayed on the display unit 140 and selects the road. It is also possible to input the route search value of the lower than the route search value of the pre-stored road. At this time, the navigation stores a value corresponding to the information of the selected road as a newly input value.

If the navigation system 100 operates without setting a destination, if the road environment of the road currently passing by the user is determined to be the worst due to congestion, the user selects the corresponding road displayed on the display unit 140 and selects the road. It is also possible to input the route search value of the value higher than the route search value of the pre-stored road. In this case, the navigation apparatus 100 stores the numerical value corresponding to the information of the selected road as a newly input numerical value. The route search value of the road which is input and changed and stored by the user is used when searching for the route when the destination is set by the user.

This will be described with reference to FIG. 3.

The lengths of the roads a1, the roads a2, and the roads b shown in FIG. 3 are the same, the lengths of the roads a1 + a2 and the roads c are the same, and the roads a1 and the roads a2 It is assumed that the value is 6, the value of the road b is 9, and the value of the road c is 3. It is assumed that there are no traffic lights and no other resistance elements.

The navigation apparatus 100 searches for a plurality of paths from the current location (a) to the destination (b) when the destination (b) is set. In this case, the plurality of paths include a road a1 and a road b. The navigation apparatus 100 calculates the cost of each path, determines a path corresponding to the lowest cost among the calculated costs, and guides the destination to the destination (B) along the determined path. That is, since the road lengths of the road a1 and the road b which are the plurality of paths are the same, the road a1 having a low value becomes the search path which is the optimum path, and the navigation 100 follows this road a1. You will be guided to your destination.

In addition, when the destination C is set, the navigation apparatus 100 searches for a plurality of paths from the current location A to the destination C. In this case, the plurality of paths include a road a1 + a2, a road b + a2, and a road c. The navigation apparatus 100 calculates the cost of each path, determines the path corresponding to the lowest cost among the calculated costs, and guides the destination to the destination along the determined path. That is, since the total road lengths of the roads a1 + a2 which are the multiple paths, the road b + a2, and the road c are the same, the road value between the paths is compared. That is, the road a1 + a2 has a value of 6, the road b + a2 has a value of 7.5, the road c has a value of 2, and the road c having a low value has an optimal path, and the navigation path 100 ) Leads along this road c to the destination c.

However, if at least one road (b) is selected according to the user's experience and the route navigation value of the road is changed from 9 to 5, the navigation 100 changes and stores the previously stored value of the road or provides information. When the information on the at least one road b is changed from 9 to 5 from the server 200, the navigation 100 changes and stores the path search value of the corresponding road.

Then, when the destination (B) is set by the user, a plurality of paths from the current location (A) to the destination (B) are searched, and a path having a low cost among the searched paths is determined to determine a destination (A) along the determined path. B) to guide.

In this case, the plurality of paths include a road a1 and a road b. The navigation apparatus 100 calculates the cost of each path, determines a path corresponding to the lowest cost among the calculated costs, and guides the destination to the destination (B) along the determined path. That is, since the road lengths of the road a1 and the road b which are the plurality of paths are the same, the road b having a low value becomes the search path which is the optimal path, and the navigation 100 follows this road b. You will be guided to your destination.

In addition, when the destination C is set, the navigation apparatus 100 searches for a plurality of paths from the current location A to the destination C. In this case, the plurality of paths include a road a1 + a2, a road b + a2, and a road c. The navigation apparatus 100 calculates the cost of each path, determines the path corresponding to the lowest cost among the calculated costs, and guides the destination to the destination along the determined path. That is, since the total road lengths of the roads a1 + a2 which are the multiple paths, the road b + a2, and the road c are the same, the road value between the paths is compared. That is, the road a1 + a2 has a value of 6, the road b + a2 has a value of 5.5, the road c has a value of 2, and the road c having a low value has an optimum path, and the navigation path 100 ) Leads along this road c to the destination c.

In this way, the user may directly input a route search value corresponding to the actual use value of the road, and may search for an optimal route since the route is searched by using it according to a destination when the next route is searched.
