When the vehicle arrives at a destination and stops, the GPS generates a position signal indicating that the vehicle has stopped, and the control unit 307 determines whether or not the first destination, which is the destination set by the user, (S120)

If the first destination and the second destination are different according to the comparison result, the control unit 307 additionally stores the link of the second destination in the storage unit 304 as the link of the destination (S130, S140).

In the destination setting step S110, the controller 307 sets the link closest to the destination among the links connected to the destination as the first destination.

In step S120, the control unit 307 obtains the stop position by performing map matching on the stop position of the vehicle and the map data, and determines whether the first link including the first destination and the stop When the second links including the two destinations are different, the first destination and the second destination are determined to be different. However, if the first link including the first destination and the second link including the second destination are the same, the control unit 307 determines whether the first destination and the second destination are within a predetermined range .

The control unit 307 determines that the first destination and the second destination are the same destination when the first destination and the second destination are within a predetermined range in step S 120, And determines that the first destination and the second destination are not the same destination if the first destination and the second destination are outside a predetermined range.

The destination is set based on any one of POI (Point Of Interest), destination peripheral facility, and screen scroll means.

If the first link including the first destination and the second link including the second destination are different from each other, the second link is stored as a link further connected to the destination in the additional storage step (S140) of the destination A detailed link is generated based on the traveling route from the first destination to the second destination and is stored as a link further connected to the destination when the detailed link of the destination does not exist and the peripheral link of the destination is set as the destination. (304). ≪ / RTI >

In addition, in the additional storage step (S140) of the destination, when there is a link including the destination but the correct address of the destination does not exist, based on the traveling route from the first destination to the second destination The destination is corrected.

Referring to FIG. 6, a vehicle navigation method according to another exemplary embodiment includes a step S210 of setting a source and a destination of a vehicle by a user, a step S210 of setting a destination link to a predetermined destination when at least two destination links are connected to the set destination, (S210, S220); And setting the selected destination link as the default destination link of the destination according to the request (S240).

In step S220, the control unit 307 displays the at least two destination links on the screen of the display unit 305 to request to select any one of the destination links. In this case, the control unit 307 detects feature information for each of the at least one destination link for selection of a destination link of the user and displays the feature information on the screen, or detects the feature information and guides the feature information.

If the user inputs a selection signal for changing the link of the destination, the predetermined destination link is changed to the selected destination link and the user inputs the change signal of the destination link If not, the predetermined destination link is confirmed as the final destination.

When the determination of the destination is completed, the navigation device 300 searches for the traveling path between the starting point and the destination based on the selected destination link.

FIG. 7 is a flowchart showing a car navigation method according to another embodiment of the present invention, and FIG. 8 shows a destination of a route on which a vehicle is to be driven.

Referring to FIG. 7, a vehicle navigation method according to another embodiment includes a step (320) of setting a destination of a vehicle to select one of links when there are at least two links connected to its destination; (S360) of comparing a first destination set by the user with a second destination of the vehicle where the vehicle actually stops, when the vehicle has arrived at a destination set according to the selection request and stopped; And adding and storing a second link including the second destination as a destination link when the first destination and the second destination are different according to the comparison result (S380).

Generally, a car navigation system sets a destination of a vehicle, and a link closest to a destination is set as a destination. Referring to FIG. 8, when the building D is set as a destination, the vehicle navigation apparatus sets the link A closest to the building D and the closest link B among the links B as a destination.

The control unit 307 determines whether a plurality of links are connected to the set destination (S320) when the user sets a source and a destination (S310), and if there are a plurality of connection links, And selects one of the destination links to request the user to change the destination link (S330).

The navigation device 300 changes the predetermined destination link to the selected destination link in step S340 and searches for the traveling path between the starting point and the destination based on the changed destination link S350). In this case, the changed destination link is set as the default link for the destination, and if the same destination as the destination is set, the changed destination link is displayed on the display unit as the default link of the destination.

In the step S330, whether or not the destination link is changed may be detected and displayed on the screen, or the feature information of each of the at least one destination link may be detected, As shown in FIG.

The comparing of the destinations (S360) can map the stop position of the vehicle and the map data using the position value of the GPS receiver or the DR sensor to obtain the second destination.

More specifically, in the comparing (S360) of the destination, when the first link including the first destination and the second link including the second destination are different, the first destination and the second If the first link including the first destination and the second link including the second destination are the same, it is determined whether the first destination and the second destination are within a predetermined range .

In this case, if the first destination and the second destination are within a predetermined range, it is determined that the first destination and the second destination are the same destination, and if the first destination and the second destination are outside a predetermined range The first destination and the second destination are determined not to be the same destination.

In the additional storing step of the destination (S380), if the destination set by the user and the vehicle's final stopping position are different, the finally stopped position is stored as the link of the set destination.

More specifically, in the case that the detailed link of the destination does not exist and the peripheral link of the destination is set as the destination, a detailed link is generated based on the traveling route from the first destination to the second destination and added to the destination Or if the link including the destination exists but the correct address of the destination does not exist, it is possible to correct the destination based on the traveling route from the first destination to the second destination.

FIG. 9 shows a traveling route to a destination that is detected according to a set start point and a destination, and FIG. 10 shows a map in which a vehicle arrives at a destination and maps a destination and a vehicle position set. FIG. 11 shows a route in which the vehicle is moved from a destination guided by the vehicle along the traveling route to another link where the user directly carries the parking lot in FIG. FIG. 12 shows a screen for requesting a user to change a predetermined destination link when at least two links are connected to a destination, and FIG. 13 is a view for explaining a case where the same destination is reset, Fig.

Hereinafter, referring to FIGS. 8 to 13, a process of storing information on a link closest to a position where the vehicle finally stops in the destination when the initially set destination and the vehicle stop position are different, Will be described in detail.

As shown in FIGS. 9 and 10, when the user sets the departure point and the destination, the navigation apparatus 300 searches for the traveling route and sets the traveling route with the link B closest to the building D as the destination. The vehicle navigation apparatus 300 determines whether the vehicle has arrived at the set destination by map matching the map data with the position of the finally guided link B along the searched traveling route. In addition, the user is informed that there is no parking lot at the set destination.

As shown in FIG. 11, since the link B is not connected to the parking lot P, the user stops the vehicle after moving the vehicle directly to the parking lot of the building D without assistance of the car navigation device.

At this time, the control unit 307 determines that the vehicle is stopped when the vehicle is turned off, and maps the position where the vehicle has stopped (the second destination) and the position of the set destination (the first destination). The controller 307 stores a link (link A) closest to the parking lot as a link connected to the destination when two map-matched positions are different from each other. In this case, the stored link information can be stored in an internal memory or in an external DB.

12, when the user resets the building D to the destination, the car navigation apparatus determines whether there are two or more links connected to the building D (S320). Since there are two links connected to the destination D A and the link B are displayed on the screen, and the user is requested to change the destination link by selecting either the link A or the link B (S330).

When the user requests the link change, the car navigation system changes the predetermined link B to the selected link A in accordance with the request (S340), and determines the traveling path between the origin and the destination based on the selected destination link (S350).

Then, when the building D is reset to the destination, the link A is displayed to the user on the default link. In this case, it is preferable that feature information on each of the link A and the link B is detected and stored together so that the feature information is displayed on the screen or guided by voice when the building D is reset to the destination.

The control unit 307 determines whether the set destination and the stop destination are different from each other. If the destination link is set as the destination due to the absence of the detailed link of the destination and the destination is set as the destination, It is preferable to generate a detailed link based on the link information and add the link of the stop destination to the destination.

In addition, when there is a link including the destination but there is no correct address of the destination, it is preferable to correct the travel route from the set destination to the stop destination in more detail.

12, when the user resets the building D to the destination, the vehicle navigation apparatus can navigate the travel route from the departure point to the link A and guide the vehicle to the parking lot of the building D.
