The present invention relates to a route display apparatus and method, and more particularly, to a route display apparatus and method capable of displaying the rotation section more clearly.

Navigation system (Navigation System) is a system for providing information for the driving of a transport device, such as a vehicle using a satellite, also referred to as an automatic navigation system. Such a navigation system receives a predetermined data from a GPS satellite floating on the earth using a GPS (Global Positioning System) receiver, and calculates its position based on the received data.

There are a number of GPS satellites floating on the earth, and the transportation device can receive GPS signals from three GPS satellites in any region of the earth and calculate its location based on the GPS signals received from the three GPS satellites. Will be.

The navigation system provides various types of travel information to the transportation apparatus such as a vehicle based on the calculated position information. Such a navigation system is conventionally used as a fixed terminal mainly for calculating a location of a vehicle and searching for a route. Various information such as the current location information of the vehicle, the route information from the current location of the vehicle to the destination, the map information related to the location information and the route information, and the traffic situation information are provided to the user.

On the user side who wants to use a navigation service, it is common to have a GSP receiver for receiving a predetermined GPS signal from a GPS satellite. In general, such a GPS receiver is designed to be mounted on a user's vehicle or the like, and provides a navigation service based on the user's location information calculated by the GPS receiver.

Recently, a navigation system can be used for a mobile communication terminal incorporating such a GPS receiving module, and in the case of a PDA, a PAD, and an MP3 player, the GPS module can be mounted to perform a GPS receiving function. Regarding a method for providing a navigation service in a fixed terminal, Korean Patent Laid-Open No. 10-2010-0091668, which is a prior art, discloses a method for effectively providing a substantial navigation service in a mobile communication terminal.

However, when driving along the movement route, when the symbol display of the intersection including the intersection, the underground road, the overpass, the highway entrance and exit road, etc. is displayed with a specific symbol, the screen size of the mobile communication terminal itself is small. Therefore, the degree of recognition is limited. In addition, when the navigation system needs to rotate, and the navigation system notifies the user only by a voice signal, the user frequently passes the rotation section because the user does not know at which point to rotate.

When there is a rotation section, a path display device and a method of overlapping a display device with a direction indicator capable of clearly indicating a rotation section from a certain distance may be provided. In addition, it is possible to provide a path display device and a method of first overlapping a direction indicator with a display device from a certain distance before, and secondly overlapping the direction indicator with the display device in a rotation section. In addition, by displaying a direction indicator on the driving line of the map when changing the direction, it is possible to provide a path display device and method that allows the user to intuitively recognize and grasp the rotation section. In addition, it is possible to provide a path display apparatus and method that can implement a simple user interface so that information can be intuitively understood in a mobile terminal. It is to be understood, however, that the technical scope of the present invention is not limited to the above-described technical problems, and other technical problems may exist.

As a technical means for achieving the above technical problem, an embodiment of the present invention is to search for a route based on the current position of the vehicle and the position of the destination input from the user interface, and route data corresponding to the searched route A path data generator to generate a first direction indicator generator to determine a first position of at least one rotation section existing on the found path, and to generate a first direction indicator corresponding to the determined rotation section; A second direction indicator processor configured to determine a second position existing before a predetermined distance from the first position based on the found path, and to generate a second direction indicator corresponding to the generated first direction indicator; And updating the current position of the vehicle and corresponding to the updated current position among pre-stored map data. The apparatus may provide a route search apparatus including a display processor configured to display the re-map data on the display device and to overlap the displayed current map data with current route data corresponding to the updated current position among the generated route data. In this case, the display processing unit overlaps the second direction indicator with the displayed current map data when the updated current position corresponds to the second position, and when the updated current position corresponds to the first position. The first direction indicator may overlap the overlapped current map data.

In addition, another embodiment of the present invention, generating the route data based on the current position of the vehicle and the position of the destination input from the user interface, the first of the at least one rotation section existing on the generated route data Determining a location, generating a first direction indicator corresponding to the determined rotation section, determining a second location that exists before a predetermined distance from the first location based on the found route, Generating a second direction indicator corresponding to the generated first direction indicator, updating a current position of the vehicle, and displaying current map data corresponding to the updated current position among previously stored map data on a display device; Step, the current route corresponding to the updated current position of the generated route data Overlapping the displayed current map data with the displayed current map data, overlapping the second direction indicator with the displayed current map data when the updated current location corresponds to the second location; The method may further include overlapping the first direction indicator with the overlapped current map data when corresponding to a first location.

According to any one of the above-described problem solving means of the present invention, by displaying the direction indicator directly on the driving line of the map at the time of switching direction, by intuitively guiding the driving information, the route data that allows the user to recognize the correct direction and route Can provide. In addition, according to any one of the above-described problem solving means of the present invention, by overlapping the direction indicator to the driving line from a certain distance, the user exactly knows where to change direction on the road where there may be a plurality of intersections can do. In addition, according to any one of the problem solving means of the present invention described above, when the user reaches the direction change position that was recognized as a direction indicator overlapping a certain distance before, by the user once again informs the corresponding rotation section by the direction indicator, It is possible to provide a route search service that prevents the user from going to a place where he or she must change direction and not arriving at the destination at a scheduled time.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "electrically connected" with another part in between . Also, when an element is referred to as "including" an element, it is to be understood that the element may include other elements as well as other elements, And does not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

1 is a block diagram illustrating a route search system according to an embodiment of the present invention. Referring to FIG. 1, the path search system 1 includes a path search apparatus 100, a network 10, and a path search server 300. At this time, each component of FIG. 1 constituting the path search system is generally connected through a network.

For example, as illustrated in FIG. 1, the path search server 300 is connected to the path search apparatus 100 through a network. The network refers to a connection structure capable of exchanging information between nodes such as terminals and servers. An example of such a network is the Internet, a LAN (Local Area Network), a Wireless LAN Local Area Network (WAN), Wide Area Network (WAN), Personal Area Network (PAN), and the like. In addition, since the route search apparatus 100 disclosed in FIG. 1 is merely illustrated for convenience of description, the route search apparatus and the server of the present disclosure are not limited to those illustrated in FIG. 1.

Referring to FIG. 1, the route search apparatus 100 may receive updated map data, real-time traffic information, etc. from the route search server 300.

At this time, in order to receive real-time traffic information, a communication module capable of receiving data such as DMB, CCTV, traffic broadcasting, various broadcasts such as Korea Expressway Corporation, apps, and information is built into the route search apparatus 100. Can be. An example of such a communication module includes a mobile communication terminal, navigation, MP3 player, PAD, PDA, and the like. It is not limited to this example and interpreted.

The route search apparatus 100 searches the route based on the current position of the vehicle and the position of the destination input from the user interface. At this time, the route search apparatus 100 communicates with the route search server 300 to search the route based on real-time traffic information data such as a user's current location, congestion, accident situation, weather condition, vehicle speed, lane restriction information, and the like. Information and path guidance information may be provided.

For example, a service providing real-time traffic congestion and traffic information to a DMB broadcast signal, for example, KBS, MBC, TU media, and the like, can be used, and is installed in a mobile communication terminal without the route search server 300. Data may be used by receiving various apps of real-time traffic information, which may be variously set.

The route search apparatus 100 may generate route data corresponding to the found route, determine a first position of at least one rotation section existing on the found route, and determine a first direction corresponding to the determined rotation section. You can create an indicator. For example, when using a highway from Seoul to Busan, at least one rotation section may exist when it is necessary to enter a toll gate from Seoul, or a left turn or right turn signal.

In this case, since the user is located in a fast moving vehicle, the user must accurately turn at any intersection or alley of at least one or more rotation sections unless the route search apparatus 100 accurately informs the corresponding route. I can't recognize it.

Therefore, the first position at which the rotation section occurs is determined and the first direction indicator indicating that the rotation should be performed at the first position should be displayed to the user in a size that can be intuitively recognized by the user. Here, the first position may be at least one, and the various rotation intervals to which the direction is changed may be the first position, instead of the designated one position.

In addition, the route search apparatus 100 determines a second position existing before a predetermined distance from the first position based on the found route, and generates a second direction indicator corresponding to the generated first direction indicator. can do. The second position may be located some distance from the first position.

The reason for this is that when you have reached a turn section and you tell you to turn, you can go straight through that turn section, and if you have multiple intersections or alleys, you will know exactly which turn section to turn. Because you can't. Thus, the second direction indicator can be shown on the travel line before the first direction indicator appears.

In this case, the second direction indicator may be displayed to the user in a size that can be intuitively recognized by the user. In addition, the second position may be at least one, and may not be a designated one position, but may be a second position transition of a predetermined distance of various rotation sections that are changed in direction.

The route search server 300 may be configured to update map data of the route search apparatus 100 or may be configured to receive real-time traffic information using various kinds of signals.

FIG. 2 is a configuration diagram of the path search apparatus shown in FIG. 1 and will be described with reference to FIG. 4. 2 and 4, the path search apparatus 100 may include a path data generator 110, a first direction indicator generator 130, a second direction indicator processor 150, and a display processor 170. It includes. but. 2 is only one embodiment of the present application, and various modifications are possible based on the components shown in FIG. 2. Anyone with knowledge can understand.

The route data generator 110 may search the route based on the current position of the vehicle and the position of the destination input from the user interface, and generate route data corresponding to the found route.

At this time, the coordinate data of the position where the route search apparatus 100 is located from the GPS satellite (not shown) can be received, and when generating route data to any destination input from the user interface, the route search server 300 ) Can receive real-time traffic conditions. When receiving a real-time traffic situation, it is possible to generate a recommended route to avoid a section that is congested due to various reasons such as congestion and lane change.

The first direction indicator generator 130 may determine a first position of at least one rotation section existing on the found path, and generate a first direction indicator corresponding to the determined rotation section.

The first location may be all rotation sections existing on the path selected by the user among the recommended paths. For example, it may be a rotation section such as a left turn at the intersection and an entry section of the IC. This may be at least one or more on the path, and the first location may be at least one or more rotational segments present on the path, rather than a fixed point.

The first direction indicator corresponding to the rotation section may be, for example, a right turn indication when the right turn is to be made, or a left turn indication when the left turn is to be made. For example, the first direction indicator may be generated in a size of 1/12 to 1/2 of the screen so that the user can intuitively grasp the rotation section even on a screen such as a navigation screen or a somewhat smaller screen such as a mobile communication terminal.

The second direction indicator processing unit 150 determines a second position existing before a predetermined distance from the first position based on the found path, and generates a second direction indicator corresponding to the generated first direction indicator. can do.

That is, although the first direction indicator may be displayed in correspondence with the rotation section, displaying when the first direction indicator is close to the rotation section may result in an accident by bending the handle rather suddenly. Accordingly, the second direction indicator may be displayed at the second position existing before the predetermined distance from the first position.

For example, the second direction indicator may be located within 1KM to 500M from the first position. The second direction indicator may be displayed only in the second position, but may be continuously displayed, for example, until it approaches the first position from the second position.

Alternatively, the second direction indicator may be displayed at intervals of 10 seconds, for example, from a second position until the first position is reached at a predetermined time interval. Alternatively, the second direction indicator may be displayed at intervals inversely proportional to the distance between the second position and the first position. For example, when the distance interval between the second position and the first position is 700M to 600M section, it is displayed once every 10 seconds, and when the distance interval is 600M to 500M section, it is displayed twice every 10 seconds and 500M to In the case of 400M section, the display interval may increase as the distance is reduced by displaying three times every 10 seconds.

The display processor 170 updates the current location of the vehicle, displays current map data corresponding to the updated current location among previously stored map data on the display device, and displays a current path corresponding to the updated current location among the generated route data. The data can overlap the current map data displayed. That is, the current location can be obtained from a GPS satellite (not shown), and can be updated in real time or periodically to determine the current location of the vehicle.

The display processing unit 170 overlaps the displayed current map data when the updated current position corresponds to the second position, and when the updated current position corresponds to the first position, the display unit 170 displays the first direction indicator. Overlapping current map data may be overlapped.

Here, the overlap is a technique that can compare and examine two or more images by overlapping, and can grasp the current map data corresponding to the current location, but the first direction indicator and the second direction indicator are superimposed thereon. As a result, the present invention may be a technique for allowing the user to recognize all of the current map data, the first direction indicator, and the second direction indicator.

The display processor 170 may express the first direction indicator and the second direction indicator in, for example, primary colors so as to be contrasted with the color of the map data. Alternatively, any color may be used as long as the color can be intuitively recognized by the user as a color contrasted with the map data.

In addition, the vehicle may be positioned on a circular shape on the searched path, and may be shown in a plan view of a color contrasted with the circular shape. In addition, the display processor 170 may overlap the first direction indicator and the second direction indicator on a path of a point spaced a predetermined distance from the point where the vehicle is located. Instead of the existing arrows, the user interface (UI) can be enhanced by showing an image like an icon such as directly looking at a vehicle. The location of the vehicle, which was difficult to distinguish from the arrow on the existing route line, is shown in a plan view of the vehicle and displayed so as to be contrasted with the color of the circle, so that the user can accurately recognize the position and the turning section or the section to be advanced. .

The display processor 170 may display the first direction indicator and the second direction indicator to blink at predetermined time intervals. For example, the blinking interval of the second direction indicator may be inversely proportional to the distance between the first position and the second position.

For example, if the distance between the first position and the second position flashes the second direction indicator once every 10 seconds at 500M to 400M, the second direction indicator blinks 10 times every 10 seconds at 100M to 0M. For example, the closer the distance is, the longer the blinking interval can intuitively recognize the rotation section. Alternatively, the flashing may be continuously performed at a predetermined time interval regardless of the distance between the first position and the second position.

The display processor 170 may overlap the first direction indicator and the second direction indicator with the size of 1/9 to 1/2 of the size of the display device in the center of the display device. In order to allow the user to intuitively recognize the rotation section even on a small screen such as a mobile communication terminal, an image much larger than a normal arrow may be shown in the center on the path line. In addition, the second direction indicator may be shown on the display device from 1KM to 500M before the first position.

In addition, the display processor 170 displays the first direction indicator and the second direction indicator to blink at intervals of 0.2 seconds to 3 seconds, and each time the first direction indicator and the second direction indicator are turned on, a buzzer or a voice is displayed. It may output a sound including a. For example, suppose you turn on the second direction indicator every three seconds when 500M is left. You will hear a beep that sounds "beep, beep" every three seconds, or a voice that says "500M left, 400M left." It may be. The buzzer or voice can be changed to another buzzer sound or sound according to the user's convenience.

The display processor 170 may overlap the first direction indicator and the second direction indicator on the searched path, that is, on the travel line. In addition, the display processor 170 may overlap the first direction indicator and the second direction indicator on a path of a point spaced a predetermined distance from the point where the vehicle is located. For example, by positioning the vehicle on a route line to which the vehicle should go and displaying an arrow before it, the image of the vehicle and the first direction indicator and the second direction indicator may not overlap.

In addition, the path search apparatus 100 is, for example, a wireless communication device that ensures portability and mobility, and includes a personal communication system (PCS), a global system for mobile communications (GSM), a personal digital cellular (PDC), and a personal PHS (PHS). Handyphone System (PDA), Personal Digital Assistant (PDA), International Mobile Telecommunication (IMT) -2000, Code Division Multiple Access (CDMA) -2000, W-Code Division Multiple Access (W-CDMA), Wireless Broadband Internet (WBRO) terminal, All types of handheld based wireless communication devices such as smartphones, tablet PCs, etc. may be included.

3 is a diagram illustrating a process in which data is transmitted and received between each component included in the path search system of FIG. 1 according to an embodiment of the present invention. Hereinafter, an example of a process of transmitting and receiving a signal according to an embodiment of the present application will be described with reference to FIG. 3, but the present disclosure is not limited to such an embodiment, and according to various embodiments described above with reference to FIG. 3. It is apparent to those skilled in the art that the process of transmitting and receiving data shown in FIG. 5 may be changed.

Referring to FIG. 3, when a destination is input to the route search apparatus 100 (S3100), the route search server 300 is requested to the route search server 300 through the network 10 in real time between the current location and the destination (S3120). S3130).

The requested route data is transmitted to the route search apparatus 100 through the network again (S3150, S3160), and when route data is generated with reference to real time information (S3160), the first position and the first direction corresponding to the rotation section are provided. An indicator is generated (S3170). In addition, a position spaced apart from the first position by a predetermined distance is set as the second position, and a second direction indicator is generated (S3180).

Then, the current map data is displayed (S3190), when the current position is the second position, the second direction indicator is overlapped (S3210), and when the current position is the first position, the first direction indicator is overlapped ( S3230).

4 is a diagram illustrating a screen of a route searching apparatus according to an embodiment of the present invention. Referring to FIG. 4A, the route data 111 may show a route to a destination set by a user. This may overlap with a different color from the current map data, and may further display an arrow in the corresponding direction.

At the intersection of Sadang Station, in order to move toward Nakseongdae, you must turn left in front of 500M from your current location. At this time, if the left turn is notified when approaching the left turn section, it may be difficult to change lanes in order to ride the left turn lane in the complex and many lanes called Sadang Station.

Accordingly, by displaying the second direction indicator 131, for example, an arrow at least before 500M of the turning section, it is possible to recognize that the driver should turn left in front of 500M, and change the lane before 500M to safely enter the left lane. . Accordingly, the inconvenience of having to bypass the road due to going straight ahead can be eliminated.

In addition, referring to FIG. 4B, when the vehicle is close to the left turn, unlike the map, there may be various left turnable alleys in the actual terrain, and thus, the first direction indicator 131 indicates where to turn left. Can be. For example, a driver who actually drives needs to look at the navigation service at the same time, so he knows that he is only turning left, but he can intuitively figure out which alley to go or where to turn left. Often not.

Therefore, through the first direction indicator 131 according to the present invention, it is possible to intuitively determine in which section the left turn exactly.

5 is a flowchart illustrating a path searching method according to an embodiment of the present invention.

First, the route data is generated based on the current position of the vehicle and the position of the destination input from the user interface (S5100).

Then, a first position of at least one or more rotation sections existing on the generated route data is determined (S5200).

In this case, a first direction indicator corresponding to the determined rotation section is generated (S5300), and a second position existing before the predetermined distance from the first location is determined based on the found route (S5400).

A second direction indicator corresponding to the generated first direction indicator is generated (S5500), the current position of the vehicle is updated, and the current map data corresponding to the updated current position among the previously stored map data is displayed on the display device. (S5600).

Also, the current map displaying the second direction indicator when the updated current location corresponds to the second location by overlapping the current path data corresponding to the updated current location among the generated path data (S5700). The data overlaps (S5800).

Lastly, when the updated current position corresponds to the first position, the first direction indicator overlaps the overlapped current map data (S5900).

The path searching method according to the embodiment described with reference to FIG. 5 may also be implemented in the form of a recording medium including instructions executable by a computer, such as a program module executed by the computer. Computer readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. In addition, the computer-readable medium may include both computer storage media and communication media. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Communication media typically includes any information delivery media, including computer readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave, or other transport mechanism.

The foregoing description of the present invention is intended for illustration, and it will be understood by those skilled in the art that the present invention may be easily modified in other specific forms without changing the technical spirit or essential features of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
