Apparatus and method for user-oriented path selection of a navigation terminal {APPARATUS AND METHOD FOR SELECTING USER-CENTER PATH OF NAVIGATION TERMINAL}

The present invention relates to a navigation terminal, and more particularly, to display the context information of various path selection elements for each of a plurality of paths to a user, and to directly select a path having context information satisfying the user. The present invention relates to a user-oriented route selection device and method of a navigation terminal for performing route guidance.

In general, a navigation terminal receives respective position data and absolute time data from a plurality of satellite positioning system (GPS) satellites, calculates its current position, and maps the calculated position to map data. When the destination is input, the device searches for a route from the current location to the destination according to a preset route search method, maps the map data, and then performs road guidance along the map-matched route.

Conventional route search methods include 'road priority', 'highway priority', 'shortest distance' and 'recommended route'. Each route searching method is literally a route searching method so that a national route is included among a plurality of routes from a current location to a destination, and a highway searching method is a route searching method including a lot of highways. A method of selecting a path having a distance from a current location to a destination is the closest, and a recommended path is a method of selecting a path by allocating at least two or more methods among the above methods. In addition, recently, there is a traffic information reflecting path selection method for reflecting traffic information so as to select a route having the best traffic situation.

However, the above-described methods do not know what route there is, but why the current route is selected by the condition of the set route search method among the plurality of searched routes. This is because the path selection selects a path according to a condition of a path search method preset by a device other than the user. That is, the conventional navigation terminal only provides a device-centric path selection method, not user-centered.

As described above, since the conventional navigation terminal performs the device-centered path search rather than the user-centered path, the user cannot substantially perform the desired path search and does not know whether the desired path search is performed. have.

Therefore, development of various path searching methods that can increase user satisfaction is required, and in particular, user-oriented path searching methods are required.

Accordingly, an object of the present invention is to display the situation information of various path selection elements for each of a plurality of paths and display the situation information to the user, and perform the route guidance by allowing the user to directly select a path having the situation information satisfying himself / herself. An apparatus and method for user-centered path selection of a navigation terminal are provided.

The apparatus of the present invention for achieving the above object; A map data DB storing map data including information on route selection elements, and variables for storing context information on the route selection elements and route selection elements set among the route selection elements. It has a storage unit, an altitude sensor for measuring the current altitude, and an acceleration sensor for measuring the acceleration for calculating the current speed, and calculates its current position by receiving position data and absolute time data from a plurality of GPS satellites. A display unit displaying a GPS module for outputting the measured altitude and acceleration information along with the detected paths, a path selection table including searched paths, preset path selection elements for each path, and situation information of each path selection element; Each of the set path selection elements for each of the paths to the destination in the path search; And a control unit configured to collect the situation information on the map data DB and the GPS module, generate a route selection table and provide the route selection table to the display, and map the route selected by the user to the map data to perform road guidance. do.

The method of the present invention for achieving the above object; Searching for routes to a destination when searching for a route, and collecting and calculating context information of a plurality of preset route selection elements for each of the searched routes, and then includes route information of the route selection elements of the longitude paths. Displaying a selection table; and mapping the route selected by the user in the displayed route selection table to map data, and then starting route guidance along the map-matched route.

The present invention shows the situation information on various path selection elements to the user, visually confirms the situation information of the path selection elements desired by the user, and allows the user to directly select a path with the optimal situation information of the desired path selection elements. Has the advantage of increasing the satisfaction.

The present invention is toll road, crosswalk, number of traffic lights, number of cameras and traffic accidents included in the map data for each route searched as shown in Table 1 in order to enable the user to efficiently select the route directly Various first elements such as the distance to the destination, time elevation change, traffic information and fuel consumption, etc., which are determined by the map data and various measurement values (hereinafter, the first elements and the second elements Context information for the "path selection element". The situation information is information such as the number of toll roads, the number of traffic lights, the number of crossings, the number of cameras, the distance to the destination, the estimated time of arrival to the destination, and the estimated fuel consumption, as shown in Table 1 below. In addition to such information, route selection factors may include weather information, vehicle inspection information, and surrounding facility information.

Path selection element Street time Fuel consumption Toll fee Crossing Revolutions Traffic accident area Convert height camera Traffic Light Traffic information Route 1 38.5 km 1h 5m 6.2ℓ 0 won 27 Left 11 / Right 9 5 regions + 2.1 / -2.0 12 27 retard Route 2 45.7 km 48m 7.3ℓ 3000 won 13 Left 4 / Right 3 2 areas + 1.7 / -1.6 7 16 Smoothly Route 3 42.1 km 46 m 6.9ℓ 2000 won 17 Left 5 / Right 4 0 area + 1.7 / -1.6 5 20 going slow Route 4 39.8 km 52 m 5.9ℓ 900 won 29 Left 12 / Right 10 4 zones + 0.9 / -0.8 4 24 going slow

In Table 1, fuel consumption is a value obtained by multiplying a general fuel economy by a distance. The fuel consumption may be updated with the fuel consumption consumed by the actual vehicle when driving to the destination is completed. However, in this case, the number of routes can be generated every time the destination changes, so it would be desirable to update the fuel consumption consumed by the actual vehicle as the fuel economy divided by the mileage or as the average fuel economy for the completion of several destinations.

The traffic information is information on an average value of traffic information weights for each section of each route. For example, the traffic information (weight: 1), slow motion (weight: 0.6), congestion (weight: 0.4), delay (weight: 0.2), and the average value of any route is 0.6, the traffic information in Table 1 Becomes If the average value of the arbitrary route is 0.9, the traffic information is determined to be a smooth traffic, and if it is 0.7, it is determined to be slow. If the median value is 0.8, it is determined to be higher-level information (for example, 0.8 is also applicable to a traffic-absent case).

The altitude conversion is represented by the maximum / minimum of the corresponding route, and may be represented by the average as the traffic information.

In addition, the present invention displays a path selection table as shown in Table 1 by displaying a background color or a text color differently at an optimal value in each field of the path selection elements.

In addition, the present invention may add or delete the path selection elements so that only the path selection elements desired by the user are displayed.

In addition, in the present invention, the situation information of the route selection elements updates the situation information by information measured or added while driving the vehicle when the destination arrives.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that in the following description, only parts necessary for understanding the operation according to the present invention will be described, and descriptions of other parts will be omitted so as not to deviate from the gist of the present invention.

1 is a view showing the configuration of a navigation terminal according to the present invention.

Referring to FIG. 1, the navigation terminal according to the present invention includes a control unit 10, a storage unit 20, a map data DB 30, an input unit 40, a display unit 50, a GPS module 60, and traffic information. The receiver 70 and the interface unit 80 is included.

The controller 10 controls the overall operation of the navigation terminal. In particular, the controller 10 searches for a plurality of routes to a destination when searching for a route, collects context information of preset route selection elements for each of the found routes, and collects the collected context information. As shown in FIG. 1, the display unit 50 displays the display unit 50. In addition, the controller 10 displays a preset path selection element and a path selection element that are not set when the path selection element editing command is input, and controls an operation of editing the path selection elements according to a user's addition or deletion. In addition, the controller 10 stores the situation information changed during the guidance of the route selected by the user and the situation information changed at the end of the route guidance, and updates the situation information previously set by the stored situation information. For example, in the above Table 1, when the user selects route 4 to guide the route, the fuel amount is measured at the start and the end of the route guidance, the fuel consumption is measured by the difference between the measured fuel amounts, and the measured fuel. The situation information of the fuel consumption path selection element of Table 1 is updated with the consumption amount. It is also possible to update fuel consumption by dividing the fuel consumption over the entire route 4 by the travel distance. In addition, the situation information update may be performed only for the path selection element selected by the user. In addition, the controller 10 classifies the traffic information input through the traffic information receiver 70 for each section and stores the traffic information in the storage unit 20.

The storage unit 20 includes a control program storage area for storing a control program for controlling the operation of the navigation terminal, a temporary area for temporarily storing data generated during the execution of the control program, data generated by a user, and the setting. Or a variable storage area for collecting and storing unconfigured path selection elements and contextual information about each of the selected elements, the path selection table generated by the controller 10 and displayed on the display unit 50; It is composed of a data storage area for storing traffic information for each section.

The map data DB 30 stores map data according to longitude and latitude. The map data includes road information (including road type and branch information), cameras on the road, traffic lights, toll roads, traffic accident areas and information (including location information), and altitude information.

The input unit 40 includes a plurality of keys for the user to control the functions and operations of the navigation terminal, and outputs key data (or “commands”) about the keys pressed by the user to the controller 10.

The display unit 50 is a liquid crystal display (LCD) or a touch screen, and displays an operation state and map data of a navigation terminal and various information according to a current operation state. In particular, the display unit 50 displays a path selection table as shown in Table 1 when searching for a route according to the present invention, and displays a text color or a background color of optimal context information in each path selection element. In addition, when the display unit 50 is a touch screen, the controller 10 outputs a coordinate value (or “command”) for a portion touched by the user to the controller 10.

The GPS module 60 includes an altitude sensor for measuring altitude and an acceleration sensor for measuring an acceleration for calculating a traveling speed, and receives positional data and absolute time data from a plurality of GPS satellites through an antenna ANT1. It calculates its own position, and outputs the calculated current position information and the measured altitude and acceleration information to the controller 10.

Traffic information receiving unit 70 is a digital multimedia broadcasting (DMB) for providing traffic information through a separate frequency modulation (FM) receiver or a TPEC (TPEC) service for receiving MBC IDIO service currently in service As a receiver, the traffic information is detected from the radio signal received through the antenna ANT2 and output to the controller 10. At this time, the control unit 10 classifies the traffic information input by the section of the map data DB 30 and stores it in the storage unit 20, and later reflects the traffic information for each section of the corresponding route when reflecting the traffic information. Get traffic information on your route.

The interface unit 80 forms a network with other electronic devices such as a transmission unit (TCU) and an electronic control unit (ECU) of the vehicle to provide data communication between the electronic devices and the control unit 10. The interface unit 80 may be a lean or can interface device that may be connected to a local interconnected network (LIN) or a controlled area network (CAN) network of the vehicle. The interface unit 80 receives the measured fuel amount by performing data communication according to the lean or can protocol with the apparatus for measuring the fuel of the vehicle according to the present invention and provides it to the controller 10.

2 is a flowchart illustrating a user-centered path selection method of a navigation terminal according to the present invention.

Hereinafter, a user-centric path selection method according to the present invention will be described with reference to FIGS. 1 and 2.

First, in step 211, the controller 10 checks whether a route search command after inputting a destination is input from the input unit 40 or the display unit 50.

If the path search command is input in step 211, the controller 10 proceeds to step 213 and checks whether the user selection mode is set. According to the present invention, the user selection mode is a mode for displaying a route selection element for the routes from the current location to the destination and displaying the route selection element to the user and allowing the user to directly select the route.

If the user selection mode is not set, the controller 10 proceeds to step 225 and performs a general mode route search such as a recommendation road, and maps the found route to map data, and then proceeds to step 223.

On the other hand, if the user mode is set, the controller 10 proceeds to step 215 to search for a route from the current location to the destination.

When the route is found, the controller 10 proceeds to step 215 to collect and calculate context information about preset route selection elements and then display the route selection table shown in Table 1 on the display 50. Specifically, the controller 10 collects the number of traffic lights, the number of toll roads, the number of crossings, the number of turns, the number of cameras, the number of traffic accidents, and the like, and calculates the distance of the corresponding route referring to the map data. The estimated time of arrival is calculated based on the current driving speed or the upper limit speed of the road along the route, and the fuel consumption due to fuel consumption is calculated.

After displaying the path selection table, the controller 10 proceeds to step 219 and checks whether an arbitrary path is selected from the displayed path selection table.

If an arbitrary route is selected, the controller 10 proceeds to step 221 to map and display the selected route on map data, and proceeds to step 223 to perform route guidance.

In FIG. 2, the user-oriented path selection method according to the present invention has been described. Hereinafter, a path selection element editing method of the path selection table according to the present invention will be described with reference to FIGS. 3 to 5. 3 is a flowchart illustrating a method for editing a path selection element for user-oriented path selection according to the present invention, FIG. 4 is a view showing a first example of a method for editing a path selection element according to the present invention, and FIG. 2 is a diagram illustrating a second example of a method for editing a path selection element according to an embodiment.

First, the control unit 10 checks in step 311 whether a path selection element editing command is input. The path selection element edit command may be generated by pressing a specific key of the input unit 40, or may be generated by selecting path selection element edit of a menu, and a path selection element edit button displayed on the display unit 50 may be generated by the user. It can also be caused by being pressed. The path selection element edit button may be configured to be activated only when the path selection table is displayed in the user selection mode.

At this time, if a path selection element edit command is input, the control unit 10 proceeds to step 313 and displays path selection elements previously set in the upper part and the setting list as shown in FIG. Paths that have not been marked.

After displaying the path selection table, the controller 10 checks whether the path selection element is added or deleted in steps 315 and 319.

If it is added in step 315, the controller 10 proceeds to step 317 to add the selected corresponding path selection element to the setting list. On the other hand, if it is deleted in step 315, the controller 10 proceeds to step 321 to delete the path selection element selected from the setting list and adds it to the unset list. Referring to FIGS. 4 and 5 as an example, when the user selects a path selection element displayed at the top as shown in FIG. 4 and presses delete, the selected path selection element is deleted at the top and displayed at the bottom. Conversely, if any path selection element is selected at the bottom and press add, it is deleted at the bottom and the selected path selection element is displayed at the top. In addition, in FIG. 5, selection buttons corresponding to each path selection element may be provided, and path selection elements to be displayed in the user selection mode may be set by checking the selection button.

The control unit 10 checks whether the edit mode end command is input in step 323, and repeats the above steps 313 to 321 until the edit mode end command is input.

6 is a flowchart illustrating a method of updating context information of a path selection element for user-centered path selection according to the present invention.

The controller 10 checks whether the route selected in step 411 is map-matched to start the route guidance.

When the route guidance is started, the controller 10 measures the fuel amount in step 413 and stores it as a starting fuel amount value.

After the fuel amount measurement, the control unit 10 proceeds to step 415 to count the timer (not shown) included in the control unit 10 to calculate the time.

After the timer counts, the controller 10 proceeds to step 417 to check whether a path selection element change event occurs. The path selection element change event refers to an input of a command for changing the context information of the path selection element. For example, the path selection element change event is not displayed on the screen because there is no camera at the current location on the guided route in the current map data, but the number of cameras to which the camera add command is input by the user because the camera is located at the actual location. Occurs when increased. It can also occur in the opposite case.

If a path selection element change event occurs in step 417, the controller 10 reflects and stores the changed information in the context information of the corresponding path selection element.

The controller 10 checks whether the destination arrives at step 421, and repeats the above steps 417 and 419 until it reaches the destination.

Upon arrival at the destination during the repetition, the control unit 10 proceeds to step 423 and updates the counted time with the status information of the estimated time of arrival of the route.

In addition, the controller 10 measures the current fuel amount through the interface unit 80 in step 425 and stores the current fuel amount as an arrival fuel amount value, and calculates fuel consumption by subtracting the arrival fuel amount value from the starting fuel amount value in step 427.

When the fuel consumption is calculated, the controller 10 proceeds to step 429 and updates the calculated usfy consumption with the situation information of the fuel consumption path selection element of the corresponding path and ends. The fuel consumption amount may be updated with the situation information value, but as described above, the fuel consumption amount may be divided by the distance value of the corresponding path, and the fuel consumption may be calculated, stored separately, and used to calculate the fuel consumption amount to the destination when searching for the next path.

In the above description, the situation information of the path selection element of the corresponding path is automatically updated with the changed or measured actual value. To this end, the situation information changed in step 419 of FIG. 6 and the counted time of step 423 and the fuel consumption calculated in step 427 are stored in a temporary area of the storage unit, a message asking whether to update is displayed, and in response to the message. If the user wants to update, the corresponding path selection elements should be displayed to update only the path selection elements specified by the user.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.
