Referring to FIG. 1, the navigation device 100 includes a communication unit 110, a user input unit 120, an audio output unit 130, a display unit 140, a storage unit 150, an interface unit 160, and a control unit ( 170 and the power supply unit 170 may be included. However, since the components shown in FIG. 1 are not essential, a navigation device having more or fewer components may be implemented.

Hereinafter, the components will be described in order.

The communication unit 110 may include a location information receiving module 111. Although not shown through the drawings, the communication unit 110 may further include a mobile communication module, a wireless internet module, a short range communication module, and the like, as necessary.

The location information receiving module 111 is a module for checking or obtaining the current location of the navigation device 100. A representative example of the location information receiving module 111 is a GPS (Global Position System) module. According to the current technology, the GPS module calculates information about a distance of one point (object) away from three or more satellites, and information on a time at which the distance information is measured, and then triangulates the calculated distance information. By applying, three-dimensional positional information according to latitude, longitude, and altitude of one point at a time can be calculated. Furthermore, a method of calculating position and time information using three satellites and correcting the error of the calculated position and time information using another satellite is also used. The GPS module continuously calculates the current position in real time and uses it to calculate speed information.

The user input unit 120 is a user interface for receiving various commands from a user, and its implementation is not particularly limited. For example, the input unit 130 may include a plurality of operation units (see 131 of FIG. 2) as shown in FIG. 2, which may include a key pad and a touch pad (static pressure / Blackout), wheel keys, jog switches, and the like.

In particular, the navigation device 100 generally adopts a touch screen method. In this case, the user input unit 120 may be integrally coupled with the display unit 140 to be described later, and thus may be implemented on the entire surface of the display screen. have.

The sound output unit 130 outputs a voice or sound associated with a route guide, an alarm of other information (dangerous section, traffic condition, speed limit, etc.).

The display unit 140 displays and outputs information received or processed by the navigation device 100. For example, the display unit 140 may be implemented as a liquid crystal display. In addition, as described above, when the display unit 140 and the sensor for detecting a touch operation have a mutual layer structure (that is, a touch screen), the display unit 140 may be used as an input device as well as an output device. Hereinafter, when the touch screen is used as the display unit 140, the sensor for detecting the touch operation is referred to as the user input unit 120.

The storage unit 150 may store a program (for example, a program for calculating (acquiring) a path to an input destination) for the operation of the controller 170, and the data processed by the controller 170 may be May be stored. In addition, the storage unit 150 may include a map data DB 162 for storing a map including a road section that can be routed to a personal vehicle. Storage unit 150 is coordinate information, name, transfer possible for a point (hereinafter referred to as a transfer destination) that can be transferred to public transport in a private vehicle (vehicle equipped with a navigation device), such as a route and station, stops of public transport The public transportation DB 151 may store information including information on public transportation and geographic information around the transfer area. In addition, the storage unit 150 may include a traffic condition DB 153 that stores information indicating a degree of congestion of each road section for a unit time (hereinafter referred to as traffic cater data). In addition, the traffic state information may include the degree of congestion in each road section by dividing the public transportation and personal vehicles. Each data stored in the storage unit 150 may be updated with data received through the interface unit 160.

The interface unit 160 serves as a path for the connection between the navigation device 100 and an external device. For example, the interface unit 160 receives data or power from an external device and transmits the data to each component inside the navigation device 100 or transmits data within the navigation device 100 to an external device. For example, a wired / wireless data port, an external charger port, a memory card port, an audio input / output (I / O) port, a video input / output (I / O) port, or the like may be provided in the interface unit 160. Can be included.

The controller 170 typically controls the overall operation of the navigation device 100. In particular, in relation to the navigation method for guiding a transfer route according to the example of the present invention, the controller 170 stores a route from the current position to the transfer destination with the personal vehicle and a route from the transfer destination to the destination for public transportation. Referring to 150, the search is performed, and an estimated time required according to the searched route is calculated. The controller 170 causes the display unit 140 to display the searched path and the estimated time required, and receives an input for selecting a path through the user input unit 120 from the user. Thereafter, the controller 170 may guide the selected path to the user through the display unit 140 and the sound output unit 130. The process of guiding the transfer route of the controller 170 will be described in detail later with reference to FIG. 3.

The power supply unit 190 receives an external power source or an internal power source under the control of the controller 170 to supply power for operation of each component.

2 is a flowchart illustrating a process of providing a transfer path in a navigation device. FIG. 3 is a diagram conceptually illustrating a route searched by the navigation device, and FIG. 4 is a view showing a screen displaying the upper transit route searched by the navigation device, and FIG. 5 is a map displaying a transit route selected by the navigation device. Figure shows a screen.

Referring to FIG. 2, in operation 310, the navigation device 100 receives an input for requesting a transit path search and a destination from a user. The navigation device 100 may display a keypad on the display unit 140 to receive an input for a destination from a user. The input destination may be displayed in an input box. At this time, the navigation device 100 displays a transfer route button, which is a button for requesting guidance of the transfer route, and when the user presses the transfer route button, the navigation apparatus 100 may perform a process subsequent to step 320.

In operation 320, the navigation apparatus 100 searches for a route from the current location to the destination only via a personal vehicle and a transfer route to the destination, and calculates an estimated time required for the found route. Referring to FIG. 3, the navigation device 100 searches for a route from the current location to the transfer point with reference to the public transportation DB 151 and the map data DB 152. In addition, the navigation device 100 searches for a route from public transit to a destination by public transportation with reference to the public transportation DB 151. That is, the navigation device 100 reaches a transfer destination by a personal vehicle, and searches for a route reaching the transfer destination to the destination using public transportation. Of course, the navigation device 100 may search for a route from the current location to the destination using only a personal vehicle that does not use public transportation.

 Referring back to FIG. 2, in step 330, the navigation device 100 calculates a time (hereinafter, referred to as an estimated time required) that is expected to be used when reaching a destination through each path found in step 320. For example, the navigation device 100 checks the traffic condition information of each section included in the vehicle route in the traffic condition DB 153. The navigation device 100 calculates an estimated time in the vehicle path from the current location to the destination by summing the time required to pass each section according to the traffic condition information. The navigation device 100 then calculates the time required to reach by public transport from the transit to the destination. The navigation device 100 calculates an estimated time required by adding the time required for the personal vehicle of each route and the time required for public transportation.

In step 340, the navigation device 100 selects a predetermined number of upper routes when the estimated time required in step 330 is arranged in a short order, and displays the selected routes. For example, the navigation device 100 may display the selected route, the transfer destination on the route, and the estimated time required for the corresponding route as shown in FIG. 4. In addition, the navigation device 100 may display information (subway line, bus number, etc.) about public transportation to be transferred on each route.

In operation 350, the navigation device 100 receives an input for selecting one of the paths displayed in operation 340 from the user.

In operation 360, the navigation device 100 displays a map indicating the route selected in operation 350. In the example referring to FIG. 4, when the user selects a route via the Seoul National University entrance area, the navigation device 100 may display a map indicating the route as shown in FIG. 5. At this time, it may be omitted according to the implementation method of the navigation device 100 in step 360.

In operation 370, the navigation device 100 guides the route from the current location to the transfer location according to the route selected in operation 350. Subsequently, the navigation device 100 guides information about public transportation to be transferred when the personal vehicle reaches the transfer destination. For example, the navigation device 100, when a personal vehicle reaches the entrance to Seoul National University, a guide message to transfer to subway line 2 in the Jamsil direction, the route using the subway line 2 from Seoul National University entrance to Bangbae Station and the vicinity of the current location You can display one or more of the map and the location of the transfer.

Although the above-described navigation apparatus 100 has been described as selecting a route through the Seoul National University entrance in step 350, when the user selects a route reaching the destination by the personal vehicle, the navigation apparatus 100 guides the route of the personal vehicle in step 370. However, the transfer instructions will be omitted afterwards.

In addition, in the navigation apparatus 110, steps 340 and 350 described above may be omitted, and a process starting from step 360 may be performed by selecting a path having the shortest estimated time.

The above-described navigation apparatus 100 automatically selects and provides a transfer destination to be transferred to public transportation according to a road condition, thereby guiding a route having a shorter estimated time required than when the user directly selects a transfer destination. have.
