Abstract

A method for setting a destination in a navigation system is provided to enable a user to easily search a destination by guiding candidate roads instead of a highway when the highway is searched as the nearest road to the destination. When an original destination is set by receiving coordinates from a user, roads are aligned in a database based on the location of the roads adjacent to the coordinates(S101,S103). When a first link of the aligned roads is a general road, a path is searched by referring to the first link as a destination(S121). When the first link of the aligned roads is not the general road, a candidate destination is set. Then, the first link or the candidate destination is set as a destination according to the selection of the user, and a path is searched(S105~S119).

The present invention relates to a method for setting a destination of a navigation system. More particularly, when a user sets a destination (first destination) in a vehicle navigation system, the nearest road (link) is not a general road for tourism or business (highway) , Urban highways, bridges, tunnels, etc.) relates to a destination setting method of a navigation system in which candidate destinations are reasonably set by setting candidate destinations as general roads for tourism or business, and allowing a user to select an initial destination and a candidate destination. .

With the diversification of wireless mobile communication services, wireless mobile communication and location tracking systems are being combined with automobiles. In particular, the vehicle navigation system that provides real-time traffic information and guides traffic information services, and the remote vehicle that informs the presence of vehicle abnormalities. There is a growing interest in telematics services that are intended to integrate diagnostics, vehicle location tracking using GPS, and additional information services that provide various information services.

The telematics system is provided in a vehicle and provides various computing functions as well as functions as a terminal for receiving various information, and a location-based information service that detects vehicle location from a control center (information center) and informs surrounding information, and a car. Remote vehicle diagnosis service that checks and controls the vehicle status by connecting the electronic control device of the vehicle, the vehicle diagnostic equipment, and the terminal to the control center, and provides a navigation service that provides traffic information to the desired destination of the driver. It will be included.

Looking at the navigation service in detail, it determines the optimal route from the starting point to the destination at the request of the user and provides the result to the user. To this end, the navigation server (information center) determines the route using the departure and destination information of the navigation vehicle and the current traffic information at the time of departure. However, when conducting route guidance from the departure point to the arrival point using the traffic information at the departure point, the traffic information after the lapse of the driving time cannot be considered, and therefore, the dynamic route guidance cannot be performed. The disadvantage is that the accuracy of the estimated arrival time is poor.

In order to make up for this drawback, in recent years, updated traffic information such as accidents and weather are regularly used to plan routes while driving and to induce changes.

On the other hand, in the conventional navigation system, the user's destination setting method sets the path to the road (link) closest to the set destination unconditionally when the user sets the destination.

However, since the destination setting method of the conventional navigation system unconditionally sets the route to the road closest to the destination set by the user, the road closest to the destination set by the user is used for tourism or work such as a highway, an urban highway, a bridge, and a tunnel. If the road is not a normal road, unwanted search results are displayed, which causes the user to not reach the destination.

Accordingly, the present invention has been made to solve the above problems, when the user sets the destination (initial destination) in the vehicle navigation system when the nearest road (link) is not a general road for tourism or business (highway, Urban highways, bridges, tunnels, etc.) provide a method for setting a destination in a navigation system that allows a user to select a destination and a candidate destination by setting a candidate destination as a general road for tourism or work, and allowing a user to select an initial destination and a candidate destination. .

A feature of the destination setting method of the navigation system according to the present invention for achieving the above object is that, when the user sets the first destination through the coordinate input, the road is aligned in the order of roads (links) close to the input coordinates in the map database A first step of doing; A second step of searching for a route using the first link as a destination when the first link among the arranged links is a general road for business and tourism; If the first link among the sorted links is not a general road for work and tourism, a candidate destination may be set, and according to a user's selection, the first link may be determined as a destination or the candidate destination may be determined as a destination. It comprises a third step of searching.

In the method for setting a destination of a navigation system according to the present invention, the candidate destination may be set as a general road adjacent to the destination having general road attributes for work or tourism such as a highway, an urban highway, a bridge, a tunnel, and the like.

The third step of the destination setting method of the navigation system according to the present invention comprises the steps of: setting a candidate destination when the first link of the sorted links is not a general road for business and tourism; Requesting to select one of an initial destination set by the user and the candidate destination; Determining a first link as a destination and searching for a route when the first destination is selected; Determining a candidate destination as a destination and searching for a route when the candidate destination is selected.

Other objects, features and advantages of the present invention will become apparent from the detailed description of the embodiments with reference to the accompanying drawings.

Hereinafter, a preferred embodiment of a destination setting method of a navigation system according to the present invention will be described.

1 is a view illustrating a configuration of a vehicle navigation system to which the present invention is applied, and a vehicle navigation system includes a GPS receiver 110, an input unit 120, a memory 130, a map database (DB) 140, , A controller 150, a display unit 160, a voice output unit 170, and a speaker 171.

The GPS receiver 110 receives the position information transmitted from the GPS satellites and the traveling speed of the vehicle. The GPS receiver 110 includes a GPS antenna and the like, and receives the position information such as the position and angle and the traveling speed information of the vehicle from the GPS satellites.

The input unit 120 is a touch screen and a keypad for generating a user manipulation signal according to a user's manipulation, and may be generally configured as a keypad device such as a keyboard for user manipulation. It is configured to be linked with the in-display device.

The memory 130 stores an application program for operating the navigation system.

The map database (DB) 140 outputs map information of the stored road network.

The controller 150 controls the overall operation of the vehicle navigation system. When the user sets a destination (initial destination), the controller 150 sets a route to a road closest to the destination and controls the guidance by interworking with a map database. Here, the controller 150 is a general CPU or microprocessor. When the road closest to the destination set by the user is not a general road for work or tourism, such as a highway, the control unit 150 automatically generates a general work or tour. It is desirable to set a candidate destination as a general road having road attributes, to allow a user to select an initial destination and a candidate destination, and to control a final destination and a route search according to the selection.

The display unit 160 displays a starting point, a destination, and the like, a currently displayed route, traffic information, parking lot location information, road information, etc. under the control of the controller 150.

The voice output unit 170 outputs a voice required for setting and guiding a path through the speaker 171.

2 is a flowchart illustrating a method for setting a destination of a navigation system according to the present invention. When a user sets an initial destination through coordinate input, a first step of arranging roads in order of roads (links) close to input coordinates in a map database is shown. (S101 to S103); A second step (S121) of searching for a route using the first link as a destination when the first link among the arranged links is a general road for work and tourism; If the first link among the sorted links is not a general road for work and tourism, a candidate destination may be set, and according to a user's selection, the first link may be determined as a destination or the candidate destination may be determined as a destination. It consists of a third step (S105 ~ S119) to search.

The destination setting method of the navigation system according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, when the user who drives the navigation system inputs a destination (first destination) by using a coordinate input method through the input unit 120 in step S101, the controller 150 receives the current position information and the vehicle speed information through the GPS receiver 110. And the like, and search the map database 140 in which the map information is stored, and display the longitude / latitude coordinates of the destination on the map through the display unit 160.

That is, when the user sets a destination through a coordinate input method, the destination location on the map is searched to display the longitude / latitude coordinates of the corresponding destination on the map.

Next, as in step S103, the roads (links) are arranged in the order of roads (links) close to the initial destination input coordinates set by the user.

If the first link is a general road for work and tourism, that is, if the first link is a general road with general road attributes for work and tourism, by checking whether it is a highway, a city highway, a bridge, a tunnel, etc. In step S121, the selected first link is determined as a destination, and the route is searched.

On the contrary, if the first link is not a general road for work and tourism, the display unit 160 and the audio output unit 170 indicate that the nearest road of the destination is not a general road for work and tourism in step S107. You will be notified.

For example, if the first link is a highway, the user is visually informed that the highway closest to the selected destination is the highway.

Next, in step S109, a map search is automatically performed to set a candidate destination as a general road having general road attributes, and in step S111, a user selects a destination.

3 illustrates an embodiment of a screen for requesting a user to select a destination after setting a candidate destination.

Thereafter, in step S113, if the user selects the first link, if the user selects the first link, the process moves to step S115 to determine the first link as the final destination, and searches for a route.

In this case, since the user wants to determine the highway as a destination, it is preferable to set it as it is.

In contrast, if the user does not select the first link, go to step S117 to check whether a candidate destination set as a road having a general road property is selected. If a candidate destination is selected, go to step S119 to select a candidate destination as the final destination. And decide to search the route.

That is, when the user sets a destination by inputting a coordinate, the present invention informs the user when the road closest to the set destination is a highway other than a general road for work or tourism, and the road is a general road having general road properties. By setting the candidate destination, the user can select the initial destination or the candidate destination, and when the destination is selected as in the related art, the difficulty of searching for the destination caused by unconditionally setting the route to the road closest to the destination is solved.

As described above, the destination setting method of the navigation system according to the present invention, when the user sets the destination through the coordinate input, if the road closest to the set destination is a highway rather than a general road for work or tourism It informs the user, sets the candidate destination as a road having general road properties, and then allows the user to select the first destination or the candidate destination. When selecting a destination as in the conventional case, the path is unconditionally set to the road closest to the destination. There is an excellent effect that solves the difficulty of searching for a destination.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims and their equivalents.
