For example, when the terminal 110 transmits a service request message to the server 100 through the network 120 under the control of the application, the server 100 transmits a code corresponding to the service request message to the terminal 110. The terminal 110 may provide content to a user by configuring and displaying a screen according to a code under the control of an application.

2 is a block diagram illustrating an internal configuration of a terminal and a server according to an exemplary embodiment.

Although FIG. 2 illustrates an internal configuration of one terminal and one server, the same or similar internal components may be applied to other terminals or other servers that may be included in the network environment described with reference to FIG. 1.

The terminal 110 may include, for example, a processor 200, at least one application 201, a memory 202, a communication module 203, and an input / output interface 204.

The server 200 may include a processor 211, a memory 212, and a communication module 213. The memories 202 and 212 are computer-readable recording media and may include permanent mass storage devices such as random access memory (RAM), read only memory (ROM), and disk drives.

These software components may be loaded from a computer readable recording medium separate from the memories 202 and 212. Such a separate computer-readable recording medium may include a computer-readable recording medium such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, a memory card, and the like. In other embodiments, software components may be loaded into the memory 202, 212 via the communication module 203, 213 rather than a computer readable recording medium. For example, at least one program is a program installed by files provided by a file distribution system (for example, the server 100 described above) through the network 120 for distributing installation files of developers or applications (for example, May be loaded into the memory 202 or 212 based on the above-described application).

Processors 200 and 211 may be configured to process instructions of a computer program by performing basic arithmetic, logic and input / output operations. Instructions may be provided to the processors 200, 211 by the memory 202, 212 or the communication modules 203, 213. For example, processors 200 and 211 may be configured to execute instructions received in accordance with program codes stored in recording devices such as memories 202 and 212.

The communication modules 203 and 213 may provide a function for the terminal 110 and the route guidance server 100 to communicate with each other through the network 120, and may provide a function for communicating with another terminal or another server. Can be. For example, a request generated by the processor 200 of the terminal 110 according to a program code stored in a recording device such as a memory 202 may be routed through a network 120 under the control of the communication module 203. 100). Conversely, control signals, commands, contents, files, and the like provided according to the control of the processor 211 of the server 100 are transmitted through the communication module 213 and the network 120 to the communication module 203 of the terminal 110. It may be received by the terminal 110 through. For example, the control signal or command of the route guidance server 100 received through the communication module 203 may be transmitted to the processor 200 or the memory 202, and the content or file may be transmitted to the terminal 110. This may be stored as a storage medium that may further include.

The input / output interface 204 may be a means for interfacing with the input / output device. For example, the input device may include a device such as a keyboard or mouse, and the output device may include a device such as a display for displaying a communication session of an application. As another example, the input / output interface 204 may be a means for interfacing with a device in which functions for input and output are integrated into one, such as a touch screen. More specifically, the processor 200 of the terminal 110 may use a service screen configured by using data provided by the route guidance server 100 or another terminal in processing a command of a computer program loaded in the memory 202. Content may be displayed on display 205 via input / output interface 204.

In addition, in other embodiments, the terminal 110 and the server 100 may include more components than the components of FIG. 2.

More specifically, when the terminal 110 is a smart phone, the acceleration sensor or gyro sensor, a camera module, various physical buttons, a button using a touch panel, an input / output port, a vibrator for vibration, and the like generally included in the smart phone Various components may be implemented to be further included in the terminal 110.

3 is a block diagram illustrating an example of a component that may be included in a processor of a server according to an embodiment. FIG. 4 is a flowchart illustrating an example of a method for guiding a path of a server according to an embodiment.

The processor 211 of the server 100 may include a course generator 310, a mapping unit 320, a path guider 330, and an updater 340. The components of the processor 211 may be representations of different functions performed by the processor 211 according to a control command provided by the program code stored in the server 100. The processor 211 and the components of the processor 211 may control the server 100 to perform steps 410 to 440 included in the route guidance method of FIG. 4. In this case, the processor 211 and the components of the processor 211 may be implemented to execute instructions according to code of an operating system included in the memory and code of at least one program.

The processor 211 may load the program code stored in the file of the program for the path guidance method into the memory. For example, when a program is executed in the server 110, the processor may control the server to load program code from a file of a program into a memory under control of an operating system. In this case, each of the processor generator 211 and the course generator 310, the mapping unit 320, the path guider 330, and the updater 340 included in the processor 211 and the processor 211 may correspond to the program code loaded in the memory. It may be different functional representations of the processor 211 for executing the instructions of the portion to execute the subsequent steps 410-440.

In operation 410, the course generator 310 may generate a course based on context information according to the drive category. In this case, the situation information may mean all information that can be obtained in relation to the drive category. For example, a drive category may be received through the terminal. Examples of the drive category may include various categories such as a restaurant drive, a trial drive, a theme drive, a revolver drive, or a healing drive. Drive categories may also be added. The course generator 310 may filter the contextual information on the drive category based on the option information set to drive the route, and generate a course based on the filtered contextual information. For example, the option information may include information that is set to travel the route such as fast, low speed, and leisurely. In this case, the course generator 310 may reflect real-time traffic information to apply the option information. For example, the course generator 310 may generate a course based on real time traffic information, or the course generator 310 may set real time traffic information as a default value, and combine information other than the real time traffic information. You can create a course. In detail, the course generator 310 may generate a course by combining real time traffic information with one or more of weather information, terrain information, photo information related to satellite photography, or other additional information.

The course generator 310 may generate various courses based on the situation information on the drive category. For example, when the starting point is the same as the destination, the course generation unit 310 may provide a user interface for inputting at least one waypoint, and generate a circular route including the starting point and the destination based on the waypoint input through the user interface. Can be generated. In this case, the circular route may mean that the starting point and the destination are the same, but the path moving from the starting point to the destination and the path moving from the destination to the starting point are different.

As another example, the course generator 310 may generate a comfortable course in consideration of temperature, climate, humidity, and the like. The course generator 310 may generate a course based on weather information and terrain information including temperature, climate, or humidity. For example, the course generator 310 may generate a course by receiving each of the terrain information including the road surface temperature, temperature, climate or humidity, and terrain information including the contour line from a separate external server. For example, the course generator 310 may calculate a road surface temperature based on today's temperature information, and may generate a course based on the calculated road surface temperature. The course generating unit 310 may determine the temperature of the day and the temperature of the road surface to generate a course focused on a high zone to provide a path to move more coolly. Alternatively, the course generator 310 may generate a course by performing a separate operation on each piece of weather information and terrain information. At this time, the course generator 310 may be weighted with each weather information and terrain information according to the respective situation information. Accordingly, the course generator 310 may generate a course according to the weighted situation information.

As another example, the course generator 310 may generate a course based on picture information related to the satellite picture. The course generator 310 may determine a ratio of a specific color (eg, green) in the satellite image. The course generator 310 may include a road existing in the satellite image in the course when the ratio of the specific color is greater than or equal to a predetermined reference.

In operation 420, the mapping unit 320 may map the generated course to map data. In this case, the mapping unit 320 may generate a path by mapping a course to pre-stored map data. Alternatively, the mapping unit 320 may generate a path by mapping a course to map data provided from an external map server. Alternatively, the mapping unit 320 may generate a route by mapping a course to map data provided through the map API.

In operation 430, the route guide 330 may guide the route including the course mapped to the map data according to the location information of the terminal. In this case, the path guider may determine the location information of the terminal through the GPS. The route guide 330 may provide guide information related to the route (for example, turn right at the front 20M) according to the location information.

In operation 440, the updater 340 may update the feedback information received in relation to the path to the course information for generating the course. The updater 340 may score feedback information including time required information related to the route, road situation information, or comfort level. The updater 340 may update the course information for generating a course according to comparing and matching the feedback information on the path with pre-stored feedback information for each section.

5 to 10 are examples of a user interface for guiding a route in a terminal according to an embodiment.

In general, in order to generate a course connecting a starting point and a destination, an embodiment in which a driving course is provided so that the driver can drive with fun in terms of driving, unlike simply reflecting traffic information related to the traffic volume, will be described. 5 to 10 illustrate that the route is guided by generating a course for the drive category through the terminal, but may be applied to autonomous driving. For example, a driver mode driven by a user or an autonomous driving mode driven by an autonomous vehicle may be provided, and autonomous driving may be performed as the autonomous driving mode is executed. The autonomous driving may be performed by the autonomous driving vehicle, and the autonomous driving vehicle refers to a vehicle that automatically detects the road situation without a driver controlling a brake, a steering wheel, an accelerator pedal, and the like. As such, the autonomous vehicle may travel on a path including a drive course based on the information received from the server.

In addition, a destination may be selectively input before and after selecting a drive category from the user through the terminal 110. Alternatively, only drive categories can be selected without input of a destination. For example, in generating a course associated with a drive category, the server may create a course that includes a destination. The server may generate a route so that the vehicle or autonomous vehicle can move to a place associated with the drive category while moving toward the destination.

5 illustrates an example of a user interface for selecting a drive category through a terminal. The server may provide the terminal 110 with a user interface for selecting a drive category. The drive category may be displayed on the drive category screen 500 of the terminal 110. At least one of the drive categories displayed on the drive category screen 500 of the terminal 110 may be selected by the user. In this case, when a plurality of drive categories are selected from a user, a course may be generated by combining context information about the selected drive category.

Examples of the drive category may include various categories such as a restaurant drive, a trial drive, a theme drive, a revolver drive, or a healing drive. Additional drive categories may be added or deleted by the user. In this case, the server may obtain context information about the drive category selected from the user. The server may generate a course by selecting roads in consideration of context information about a drive category selected by a user.

Referring to FIG. 6, the option information screen 600 of the terminal 110 illustrates a user interface for inputting option information for driving a route. For example, the option information screen 600 of the terminal 110 may display various option information such as fast, slow, relaxed, comfortable, and low speed. Similarly, option information may be additionally added or deleted by the user. For example, as the user selects 'fast', the server may generate a course centering on a car road, a highway, or a straight course in generating a course, and as the 'low speed' is selected, the server may generate a course. In generating the, the course may be generated mainly in a place including a rare place, a small traffic volume, a low speed limit, and the like. The server may generate a course by weighting a specific road according to each option information. Accordingly, the course may be generated differently according to the option information selected by the user. In addition, option information may be selectively input separately from the drive category. For example, the server may generate a course based on drive category and option information. The server may filter the context information according to the drive category according to the option information, and generate a course based on the filtered context information. Alternatively, if the drive category is not selected, the server may basically generate a course to the destination based on the option information. This allows routes to be distributed even if they contain the same destination.

Drive categories will be described. For example, the restaurant type drive may mean a specific store in which a user moves with a purpose. For example, when a user wants to take a tour of 'chogi noodle' restaurant, it means that the chogo noodle restaurant course is generated on the screen of the terminal 110 by inputting 'jugi noodle'. In detail, the server may receive that the restaurant type drive is selected by the user through the terminal 110. In this case, as the restaurant type drive is selected, a user interface for selecting a type of food may be provided, and a type of food may be selected by the user. The server may obtain the restaurant information associated with the type of food selected by the user (e.g., the restaurant's restaurant rating, the user's restaurant reviews, the location information of the restaurant, the opening hours of the restaurant, etc.) and the obtained restaurant information of the user's location information. Based on the restaurant can be generated. In this case, when the destination is set by the user, when the previously obtained restaurant information is included in the route for moving the destination, the restaurant associated with the restaurant information may be included as a waypoint. On the other hand, in the related art, it is possible to relieve the inconvenience of having executed the tour of the noodle restaurant by searching and entering and moving to search for another noodle restaurant. Alternatively, the server may generate a course to reach a specific store (eg, fried noodle restaurant) based on a predetermined scheduled time (eg, lunch time).

An experiential drive refers to generating a place information related to a place to experience as a course. The server may receive that the body weight drive is selected by the user through the terminal 110. The server may provide a user interface for selecting the experience type to the terminal 110, and the experience type may be input or selected by the user. For example, as a user inputs a 'pottery experience' as a type of experience, the server acquires information related to the pottery experience (for example, pottery festival date, pottery festival place, pottery experience time, etc.), You can create a course that includes related places. At this time, the server determines whether the date information of the pottery experience is input and the time when the pottery festival is overlapped, and includes a place where the pottery festival is held when the date information of the pottery experience is input and the time when the pottery festival is overlapped. You can create a course.

The circular drive means that the destination and the starting point are the same, and the circular drive is generated such that the path from the starting point to the destination and the path from the destination to the starting point can be circulated and driven. Referring to FIG. 7, as a circular drive is selected from a user, a user interface related to a circular drive may be displayed on the circular drive screen 700 of the terminal 110. A user interface for inputting a waypoint for generating a circular course may be displayed on the circular drive screen 700 of the terminal 110. A waypoint can be entered from the user via the user interface. Alternatively, at least one waypoint list may be provided to recommend a recurring course from the server, and at least one of the waypoint lists may be selected. The server may generate a recurring course including an input and a selected waypoint from the user, and map the recurring course to map data to guide the recursive path. In general, when a starting point and a destination are the same, a route may not be generated, and even when a stop point is input, there is a problem that a course from a starting point to a stopping point and a course from a stopping point to a destination are generated. In contrast, the circular drive generates a circular course that circulates from the origin to the destination, including at least one waypoint, as the at least one waypoint is selected. Through the circular course, the user can move while watching the landscape.

Theme drive refers to the generation of course information related to various themes. Examples of themed drives may vary from healing drives, travel drives, amusement park drives, 4 hour course drives, drives within 100 km, and the like. Referring to FIG. 8, a user interface for selecting a color theme may be provided on the healing drive screen 800 of the terminal 110. For example, various colors such as blue, green, and red may be displayed on the healing drive screen 800. The user may select a desired color through the healing drive screen 800. For example, as the user selects blue, the server may extract areas containing blue from the satellite image, and may recommend a route including a coastal road based on the extracted areas. Alternatively, when the user selects green, a mountain road may be recommended in consideration of contour information and route information. Accordingly, it is possible to move while viewing the surrounding landscape comfortably rather than traveling on the optimum and shortest path. In addition, a comfortable path may be provided in consideration of the temperature, climate, humidity, etc. where the terminal 110 is located. In addition, the server may provide a drive course by reflecting real-time traffic information. In this case, since the traffic conditions vary depending on the time information, the driving course provided according to time may vary.

9 illustrates an example of guiding a route by mapping a course generated according to a drive category to map data. The route for the drive category corresponding to the location information of the terminal 110 may be guided on the route guide screen 900 of the terminal 110. A user interface called 'route guide start' may be provided on the route guide screen 900 of the terminal 110, and as the user interface is selected from the user, guidance about the route according to the location information of the terminal may be started. The server may guide the path corresponding to the location information of the terminal and provide guidance information on the guided path. For example, guide information such as 'turn right at 20m ahead' may be output as a message on the route guide screen 900 of the terminal 110.

10 illustrates an example of inputting feedback information in relation to a path. The user interface may be provided on the feedback screen 1000 of the terminal 110 to evaluate the satisfaction level after moving the path provided from the server. The user may evaluate the route through the feedback screen 1000 of the terminal 110. The server may store the evaluation performed by the user as feedback information. In this case, the evaluation may be given a score based on a specific score (for example, 5 points) for each item. For example, each item may be scored based on the time satisfaction, the road condition satisfaction, and the comfort level. In addition, the user may input additional comments to be additionally input as feedback information. In this case, the server may store each score for each item received from the user and an average score obtained by averaging the total score of each item.

11 illustrates an example of storing feedback information in a server, according to an exemplary embodiment.

The server may store the feedback information 1100 received from the user in a database. The feedback information 1100 may store the feedback information generated for the path for each section. For example, the server may classify the road into sections based on predetermined criteria. The server may classify the route into preset criteria in the same or similar manner to the way in which the road is divided, and input the feedback information in the matching section when the divided route matches the section. In addition, if the feedback information for each section is stored in the database, the current input feedback information can be updated by comparing and matching the previously stored feedback information for each section. Accordingly, feedback information for each section may be continuously accumulated. For example, the feedback information may be scored and accumulated in a database, and the accumulated feedback information may be averaged and stored.

Furthermore, the server may generate a course based on the feedback information for each section stored for a predetermined period. For example, course information for generating a course may be updated based on feedback information for the last 30 days. According to an embodiment, as the feedback information is continuously accumulated, the server may provide a path more accurate and desired by the user.

The apparatus described above may be implemented as a hardware component, a software component, and / or a combination of hardware components and software components. For example, the devices and components described in the embodiments are, for example, processors, controllers, arithmetic logic units (ALUs), digital signal processors, microcomputers, field programmable gate arrays (FPGAs). Can be implemented using one or more general purpose or special purpose computers, such as a programmable logic unit (PLU), a microprocessor, or any other device capable of executing and responding to instructions.
