The present invention relates to a navigation device capable of performing the above.
[0002]
[Prior art]
In the navigation device, a map / information storage medium such as a CD-ROM, a DVD-ROM, a hard disk or the like in which map data for drawing a map and facility information data for searching a facility are recorded, and the map / information storage A vehicle position detection device for detecting a current position and a direction of travel of a vehicle by a reproducing device for reading medium data, a display device for displaying a map, a self-contained navigation device such as a distance sensor and a gyro, and a GPS receiver. The map data including the current position of the vehicle is read from the map / information storage medium, the map image around the vehicle position is drawn on the screen of the display device based on the map data, and the vehicle position mark is displayed on the display screen. Overlaid and displayed, scrolls the map image as the vehicle moves, or displays the map image Fixed by moving the vehicle position mark, so that seen whether the vehicle is traveling where the current at a glance.
[0003]
Map data stored in a map / information storage medium such as a CD-ROM, DVD-ROM, or hard disk is divided into longitude and latitude widths of appropriate sizes according to various scale levels. Etc. are stored as a coordinate set of nodes expressed by longitude and latitude. A road is composed of a combination of two or more nodes, and map data displays a road layer consisting of a road list, a node table, an intersection configuration node list, etc., and roads, buildings, facilities, parks, rivers, etc. on the map screen. Map data such as a background layer, and information data for displaying characters, map symbols, etc., such as administrative division names such as municipalities, road names, intersection names, and facility names.
[0004]
In addition, this navigation device has a route guidance function that allows the user to easily travel to a desired destination without making a mistake on the road. According to this route guidance function, destinations and waypoints are set by various means using addresses, telephone numbers, map scrolling, nearby landmarks, etc., and routes connecting these points from the departure point to the destination Appropriate routes are calculated and presented in consideration of various conditions. Also, the route selected by the user is stored as a guide route, and while driving, the guide route is drawn on the map image with a different color from other routes and displayed on the screen. When approaching an intersection where the course of course should be changed within a certain distance, the intersection is enlarged and displayed on the screen by drawing an arrow indicating the direction in which the course should be changed, or a right or left turn is guided by voice. In this way, the user can be guided to the destination.
[0005]
When calculating the guidance route as described above, there are various routes such as a route that can arrive from the current location to the destination in the shortest time, a route that has the shortest travel distance, a route that uses or does not use a highway or other toll roads, etc. Calculation is performed by the route calculation method of the aspect, and each is displayed on the map in a different color. In that case, for example, as shown in FIG. 8 (a), the guidance route is superimposed on a scale map that can be displayed on one screen from the current location P to the destination M, so that the user is going to go from now on. A guide route confirmation map is displayed so that the entire process can be grasped.
[0006]
A plurality of guide routes R1 to R3 from the current position P to the destination M calculated as described above are displayed in this map for confirming the guide route in appropriate colors, and whether or not the route to be selected is appropriate. It is possible to check. At this time, the user can select another route on the menu screen or the like when the selected route or the recommended route displayed in a predetermined color such as purple is not preferable.
[0007]
Furthermore, depending on the map display above, it is unclear what kind of road the road actually travels, and when the user wants to know more detailed information on the road, details of the road can be displayed on the menu screen etc. The display is selected, and for example, a section diagram showing detailed information of the traveling road as shown in FIG. 8B can be displayed. In the example shown in the figure, when the user travels on the guide route R1 in FIG. 8 (a), first travels 2km on the general road and enters National Route 6, and then travels 32km and enters the Shin-Otone Bridge Road. After driving 6km, enter National Route 294, and after traveling 10km, enter Prefectural Road 354. If you travel 2km, it is shown that you will reach your destination. It can be confirmed whether or not the guidance route is preferable.
[0008]
[Problems to be solved by the invention]
In the conventional navigation device as described above, for the guidance route displayed on the guidance route confirmation map screen, for example, as shown in FIG. In order to know whether or not to do so, for example, it has been necessary to switch to a traveling road detail display as shown in FIG. For this reason, in this traveling road detailed information display section map screen, for example, which road part is the Shin-Otone Bridge road and national road No. 294 in the guidance route on the guidance route confirmation map screen that was previously displayed. I didn't understand, and it was troublesome because it was necessary to check the road name etc. by displaying the actual driving map screen.
[0009]
Furthermore, as a result of confirming whether or not the selected guide route is appropriate by displaying the detailed travel road information as shown in FIG. 8B, it is determined that the route is not a preferable route based on the experience of the user. When you want to select a more appropriate guide route, return to the previous guide route confirmation map screen display by operating the menu screen again, select another guide route here, and again by operating the menu screen etc. It was troublesome because it was necessary to display the detailed information on the road and make the same confirmation.
[0010]
In addition, when a guidance route is displayed and the guidance route travels on a toll road such as an expressway, the user confirms toll road travel by displaying the travel road detailed information on the guidance route as described above. When it is confirmed that the toll road is one toll road and the travel distance is relatively short, the user can easily find the toll road by instructing a search for a road that travels only on a general road that does not use the toll road. It is possible to obtain another guidance route that does not use the toll road and to perform a comparison with the case of using the toll road.
[0011]
However, it is possible to display the detailed information on the traveling road as described above that the guidance route presented first travels on a toll road such as a plurality of expressways, and the travel distance of one of the toll roads is relatively short. If you know by switching to, it is extremely difficult to set search conditions for searching for a guidance route that does not travel only on the toll road, and it takes a lot of work, so in many cases you will travel with that guidance route. Become. In that case, it is necessary to travel on a toll road of a short distance with a relatively high fee, especially when there is an appropriate general road that bypasses the toll road when the travel route is examined later. When it is known, it is not preferable because the user is dissatisfied with the navigation device.
[0012]
Therefore, according to the present invention, for the guidance route displayed on the guidance route confirmation map screen, the detailed information of the road used when actually traveling on the guidance route is made to correspond to the guidance route confirmation map screen. It is possible to confirm the same, and it is possible to easily perform the same confirmation for other guidance routes, and when there are multiple toll roads in the guidance route, use some of the toll roads. It is a main object to provide a navigation device that can easily confirm whether or not to perform, and can easily present other roads when not used.
[0013]

[0033]
In the navigation device composed of the functional block diagram as described above, the guidance route screen display processing performed by the guidance route display processing unit 1 in FIG. 1 is performed in order according to the operation flow shown in FIG. Can be made. Hereinafter, the operation flow of the first embodiment of the guidance route screen display process will be described in order with reference to the functional block diagram of FIG. 1 and the screen display example shown in FIG.
[0034]
In the guidance route screen display process 1 shown in FIG. 2, the present location as basic data for calculating the first guidance route (step S1), and the destination and the setting of the waypoint are input according to necessity (step S1). Step S2). The input of the present location can be normally performed by capturing GPS signals from a navigation device. When setting a destination or waypoint, scrolling a map, inputting an address, inputting an adjacent station name, which has been widely performed conventionally. It is possible to make settings by adopting various means such as telephone number input and to input the data.
[0035]
Next, the navigation device calculates the guidance route based on conditions such as highway priority or non-priority, shortest distance, minimum required time (step S3). At that time, even when an instruction such as highway priority has been given in advance by the user, in consideration of being asked to present another route later, other types of guidance routes are calculated, and each data is Ask.
[0036]
Next, when calculating the guidance route, it is determined whether or not there is a priority instruction input such as highway priority from the user (step S4). As shown in the figure, it is divided into left and right, and in the example screen shown, all the calculated guide route diagrams are displayed on the left side as one side, and the guide route in which the priority instruction is input within the guide route is easier than the other Is displayed in an identifiable manner (step S5). The display screen can be divided by the guide route confirmation screen division instruction unit 11 in FIG.
[0037]
The screen example shown in FIG. 3 shows an example in which all three calculated guide routes R1 to R3 from the current location P to the destination M are displayed in a divided screen. Although not clearly shown in the guide route diagram shown in the figure, the guide route R1 is a priority instruction guide route or a recommended guide route to be described later, such as the green color of the other guide route R2, the pink color of the guide route R3, etc. The guide route R1 is displayed so as to be easily distinguishable from other guide routes, such as displaying in a purple color as a specific color that is different from the color. Note that the process of displaying all of the guide routes on one screen is performed in the guide route overall view display unit 20 in FIG. 1, and the process of identifying and displaying the guide route for which priority has been specified is displayed in the selected guide route identification display unit 21. Do.
[0038]
The determination as to whether or not there is a priority instruction input in step S4 is started by a signal detected by the guidance route computation end detection unit 12 in FIG. 1 that the computation in the guidance route computation unit 5 has been completed. The determination can be made by detecting whether the user has made a priority instruction input from the instruction signal input unit 6 in the guidance route selection unit 13.
[0039]
Next, on the other side of the divided display screen, that is, in the example of the screen shown in FIG. 3, a partition diagram showing detailed information of the guidance route with the priority specified is displayed on the right screen portion (step S6). In the example of the screen shown in FIG. 3, since the guidance route R1 is the guidance route for which priority is given as described above, information on the traveling road is displayed as detailed information about the guidance route R1. In the example shown in the figure, as in the conventional example shown in FIG. 8, first drive on a general road for 2 km and enter National Route 6, then drive for 32 km, then enter Shin Otone Bridge Road and drive for 10 km. It is shown that after entering National Highway 294 and traveling 6km on this road, entering Prefectural Road 354 and traveling 2km on this road will reach the destination. The partition diagram of the priority instruction guidance route in step S6 can be displayed by a selection signal from the identification guidance route selection unit 13 in the partition diagram display unit 18 in FIG.
[0040]
On the other hand, when it is determined in step S4 that there is no priority instruction input, the display screen is first divided into two as in step S5, and in the illustrated embodiment, all calculated route maps are displayed on the left side as one side. At the same time, the guidance route recommended by the navigation device in the guidance route is displayed so as to be distinguishable from others (step S11).
[0041]
In the example of the screen shown in FIG. 3, when there is no priority instruction input as described above, when the navigation device sets the guidance route R1 as the recommended guidance route, the guidance route R1 is displayed in a specific predetermined color such as purple. Displayed in color, different from the display colors of other guidance routes, and displayed in an easily distinguishable manner. Such specific guidance route identification display processing is performed in the selective guidance route identification display unit 21 in FIG.
[0042]
Next, as in step S6, a partition map of the recommended guidance route is displayed on the other side of the divided display screen, that is, on the right screen portion in the screen example shown in FIG. 3 (step S12). In the example of the screen shown in FIG. 3, when the priority instruction as described above does not exist, the guide route R1 is shown as a recommended guide route. Information about the road is displayed. In addition, the display of the said division map is performed in the selection guidance route block diagram display part 23 in FIG.
[0043]
In the example shown in FIG. 2, after step S6 or step S12 is finished, an example is shown in which the first traveling road that first travels when the vehicle travels from the current location is identified and displayed in the guidance route map and the block diagram. (Step S7). The travel road to be selected at this time may be set to any road, but when the first travel road is displayed, the user can immediately know information on the road on which the travel is first performed. The travel road identification process can be performed in the selected travel road identification display unit 22 for the guidance route map, and can be performed in the selected travel road partition map identification display unit 24 for the section map.
[0044]
Next, it is determined whether or not there is a request for confirmation of a section map of another traveling road from the user in the guidance route (step S8). This determination can be made by detecting whether or not the user has input a request for confirming the plot of another traveling road from the instruction signal input unit 6 in the identified traveling road selection unit 14 of FIG. For example, when the user inputs a section map confirmation request for another traveling road, the user inputs a signal indicating that the user has operated the joystick of the remote controller in the front-rear direction in the state shown in FIG. Input can be performed by moving and displaying the colored display frame in the vertical direction in the figure.
[0045]
If it is determined in step S8 that the user has issued a section map confirmation request instruction for another traveling road, the traveling road instructed by the user is identified and displayed in the guidance route map and the section map (step S13). . The screen example shown in FIG. 3A shows an example in which the user has instructed to select the next road after the identification display of the first traveling road as the initial screen as described above. In the guidance route map displayed on the left side, the traveling road L portion in the guidance route R1 is displayed with a particularly thick line, and an example in which the traveling road L is displayed so as to be easily distinguishable from other traveling roads is shown.
[0046]
In the block diagram displayed on the right side of the divided screen, the national highway No. 6 display frame on which road information about the road L is shown is surrounded by a bold line, and the inside is colored and displayed, Shows an example displayed for easy identification. Thereby, for a specific traveling road in the guide route, for example, National Route 6 can easily know which part in the guide route map corresponds to. After the completion of step S13, the process returns to step S8 again to wait for an instruction for requesting detailed information display of another traveling road.
[0047]
In the screen example shown in FIG. 3B, the user again operates the joystick of the remote controller in the front-rear direction from the state shown in FIG. 3A, and the next Shin-Otone Bridge road is located on the guidance route. An example of displaying whether it corresponds to a part is shown. As a result, the thick frame for identification display and the colored portion in the frame move from "National Route 6" in Fig. 3 (a) to "Shin Otone Bridge Road" in Fig. 3 (b). Similarly, in the guidance route diagram displayed on the left side, as shown in FIG. 3B, the road portion L that travels next to the “National Route 6” on the same guidance route R1 is indicated by a thick line or the like. Is displayed.
[0048]
If it is determined in step S8 that there is no section map confirmation request instruction for another traveling road in the selected guide route, it is then determined whether there is a section map display instruction for another guide route (step S9). . This determination can be performed in the same manner as described above by detecting whether or not an instruction signal is input to the identification guide route selection unit 13 in FIG. As a result of this determination, when it is determined that there is an instruction to display a section map of another guidance route, a section diagram indicating traveling road information as detailed information is displayed for the specified guidance route (step S14). Thereafter, the process returns to step S7, and the initial screen for displaying the guidance route is identified and displayed so that the first traveling road starting the current location traveling in the guidance route and the block diagram can be easily distinguished from the others, and so on. Repeat operation.
[0049]
Further, when it is determined in step S9 that there is no instruction for displaying a map of another guide route, it is determined whether or not there is an instruction for another screen display request (step S10), and when it is determined that there is an instruction. The other requested screen is displayed (step S16). Here, when the other screen display request instruction is a display request instruction for the driving guidance route, a map screen centered on the vehicle position displayed during normal driving and the above processing on the map are performed. The guidance route finally confirmed is displayed as a guidance route selected by the user. Whether or not there is such a travel guidance route display request instruction is whether or not the user has input from the instruction signal input unit 6 in the travel guidance route display instruction input unit 16 in FIG. This can be done by detecting.
[0050]
In the embodiment shown in FIG. 2, when it is determined in step S10 that there is no other screen display request instruction, it is determined whether or not the vehicle has started (step S15). Here, the vehicle has started. If it is determined, the process proceeds to step S16, and another screen display is performed in the same manner as described above. At this time, the traveling guidance route as described above is displayed. If it is determined in step S15 that the vehicle has not yet started, the process returns to step S8. Further, it is determined whether or not there is an instruction for confirming the section map of another traveling road and the subsequent processing is performed on another screen. Repeat until display request or vehicle departure.
[0051]
The navigation device as described above is the same as the conventional guidance route detailed display as shown in FIG. 8B, which is different from the guidance route diagram shown in FIG. Since they are displayed in association with each other on the screen, the detailed information of each guide route can be easily and reliably known. Furthermore, with regard to the road on the guide route, it is possible to know at a glance which road part on the guide route corresponds to the road instructed by the user, and a function that cannot be performed by a conventional navigation device is added. It becomes possible to do.
[0052]
On the other hand, the function as described above in the present invention is also effective when presenting a guide route that travels on a general road by bypassing a specific toll road when there are a plurality of toll roads in the guide route. Can be used. The embodiment for performing the function can be implemented by, for example, a navigation device including the functional blocks shown in FIG. 4 in which other functions are added to the functions of the functional block diagram of FIG. The guide route screen display process in can be operated in order according to the operation flow shown in FIG. Hereinafter, this embodiment will be described.
[0053]

A toll road travel confirmation display unit 26 is added to the guidance route map display unit 17 and a toll road travel confirmation selection input guidance display unit 27 is further added to the section map (information) display unit 18. Moreover, the same name and the same number are attached | subjected to the functional block which performs the same function as the functional block in the navigation apparatus shown in FIG. 1, Therefore Since those detailed description overlaps with the above, description here is abbreviate | omitted. .
[0054]
The toll road traveling confirmation display unit 26 in the guidance route confirmation display unit 17 displays the guidance route map for confirming whether or not the toll road is traveling for each toll road for the selected guidance route. The function of the road identification display unit 22 is also used to display on one side of the monitor screen so that each guidance route can be identified. At this time, the toll road bypass calculation instruction unit 19 instructs the guide route calculation unit 5 to calculate the guide route of the general road that bypasses the toll road for the toll road designated by the user. The toll road travel confirmation display unit 26 performs processing for adding and displaying the bypass route guidance route obtained as a result to the previous guide route, and traveling on the toll road or traveling on the bypass route. This makes it possible for the user to easily make such a determination. As described above, in the guidance route calculation unit 5, a road that bypasses the toll road designated by the user is performed according to an instruction from the toll road bypass calculation instruction unit 19. It functions as a road bypass road calculation means.
[0055]
At this time, in the selected travel road information display unit 24, for each toll road displayed in the toll road travel confirmation display unit 26, the names of the toll roads, etc., so that the correspondence with those toll roads can be easily understood. It also performs the function of displaying information on the same screen. In addition, the toll road traveling confirmation selection input guidance display unit 27 is used to select and input whether to travel on the toll road or on the bypass road on the same screen as the above guide route map. Display guidance.
[0056]
In a navigation device composed of such functional blocks, a user travels on a general road that bypasses a specific toll road on the guide route map displayed on one side of the monitor screen and travels on the toll road. While comparing with the case, it is further referred to the toll road information displayed on the other side of the monitor screen by the selected travel road information display section 24 in the section map (information) display section 18 to travel on any route. By determining whether it is appropriate and performing selection input according to the selection input guide display displayed on the partition diagram display screen, these selection displays can be easily performed.
[0057]
In the navigation device having functional blocks as shown in FIG. 4, the guidance route screen display process can be performed in substantially the same procedure as the operation float shown in FIG. 2, for example, the operation flow shown in FIG. Can be operated in sequence. Hereinafter, the operation flow of the second embodiment of the guidance route screen display process shown in FIG. 5 will be described with reference to the functional block diagram shown in FIG. 4 and the screen display examples of FIGS. The operation flow shown in FIG. 5 is shown as an operation flow that continues from step S6 and step S12 of the operation flow of FIG. 2 as shown in step S21. It is determined whether there is a figure display instruction.
[0058]
That is, after the guidance route is calculated in the state where the guidance instruction of the guidance route has been inputted in step S6 of FIG. 2 and the process of displaying the priority indication guidance route identification display and its partition diagram on one screen, or In step S12, the guidance route is calculated in a state where there is no guidance route priority instruction input, and after performing the process of displaying the recommended guidance route identification display and its block diagram on one screen by the navigation device, the user It is determined whether or not an instruction to display detailed information on the guidance route other than the guidance route automatically identified and displayed is given (step S22). Here, when the user wants to display a block diagram of another guide route, a selection instruction is given by pointing the guide route with a cursor or the like. A figure is displayed (step S23).
[0059]
In the above state, for example, as shown in FIG. 6 (a), the three guide routes R4, R5, and R6 from the current location P to the destination M are searched, displayed on the left side of the screen, and specified in them. R5, which is the guide route, is selected, and a block diagram showing detailed information on the guide route is displayed on the right side of the screen. The state of this display is almost the same as in FIG. 3A, but in FIG. 3A, a specific road in the selected guide route can be distinguished from other roads in the same guide route. Although the displayed example is shown, the example shown in FIG. 6 (a) shows a mode in which the function for displaying the specific road in the selected guide route so as to be further identifiable is not performed at this stage. ing. Therefore, in this state, the selected travel road identification display unit 22 in the guide route confirmation display unit 10 in FIG. 4 and the selected travel road information display unit 27 in the block diagram (information) display unit 18 do not function.
[0060]
After the process of step S23, and when it is determined in step S22 that there is no instruction for displaying a block diagram of another guide route, that is, the guide displayed on the current monitor screen so as to be distinguishable from other guide routes. If it is determined that the display of the block diagram for displaying the guidance route information is to be continued for the route, it is then determined whether or not there is a toll road confirmation guidance request (step S24). For this determination, in the example shown in FIG. 6 (a), an instruction input section for "toll road confirmation guidance" is provided, and the user inputs an instruction as shown in FIG. This can be done by detecting whether or not.
[0061]
When it is determined that there is a toll road confirmation guidance request, that is, when it is determined that a toll road confirmation guidance instruction is input as shown in FIG. Is displayed in an identifiable manner (step S25). In that case, for example, as shown in the guide route diagram on the left screen of FIG. 7A, with respect to the guide route R5 selected in FIG. In addition, each guidance route is displayed so as to be distinguishable from the others, and on the right screen adjacent to the screen, information on what kind of toll road is displayed as a section map.
[0062]
The example shown in FIG. 7 shows the state of traveling on “Tohoku Expressway” and “Metropolitan Expressway”, and is displayed so that the correspondence of each road between the guide route map portion and the section map portion can be easily understood. is doing. As described above, for a plurality of toll roads on one guide route, each road is displayed so that it can be distinguished from other roads, and information such as the name of each road is displayed in association with it. This can be performed in the selected travel road identification display unit 22 in the display unit 10 and the selected travel road information display unit 24 in the section diagram (information) display unit 18. Therefore, the selected traveling road identification display unit 22 can be referred to as a selected toll road identification display unit here, and the selected traveling road information display unit 22 can also be referred to as a selected toll road information display unit.
[0063]
Next, it is determined whether or not there is a confirmation guidance request instruction for a specific toll road in the specific guidance route displayed in this way (step S26). For example, this determination is shown in FIG. 7 This is done by moving the cursor to one of the information display / selection instructing sections of “Tohoku Expressway” and “Metropolitan Expressway” displayed on the block diagram side in (a), and detecting the movement. (B) shows an example in which a confirmation guidance request instruction for “Tohoku Expressway” is performed.

In particular, in the example shown in FIG. 7, the section traveling on the Tohoku Expressway is particularly short, and as shown in FIG. If you want to know the general road that only bypasses the Tohoku Expressway. In such a case, it has been extremely difficult to search for a road that bypasses only this part. However, in this embodiment, a specific toll road is distinguished from other toll roads as described above. Therefore, it is possible to easily input conditions for not traveling on the toll road, and it is possible to easily obtain a guidance route for a general road that bypasses the condition.
[0065]
Next, a general road that bypasses the toll road indicated in the guide route map is calculated and displayed (step S27). In addition, a selection input guidance screen indicating whether or not to pass is displayed in the block diagram corresponding to the designated toll road (step S28). It should be noted that the order of steps S27 and S28 functions in the same manner regardless of which is first performed. The state after these processes is shown in FIG. 7B. As shown in the left screen in the figure, a “bypass road” that bypasses the “Tohoku Expressway” is shown, and a section that displays information on the road On the side of the figure, a screen is displayed by means of a pop-up or the like for the user to refer to this bypass road and select and enter whether or not to go through a specific toll road, “Tohoku Expressway” To do. When searching for a road that bypasses such a specific toll road, a route that travels on a general road to the middle of another toll road may be shown as a result.
[0066]
Next, it is determined whether or not there is an instruction input for passing through the instructed toll road (step S29). In the example of the screen of FIG. 7B, this determination is made according to the selection input guidance screen indicating whether or not to pass through “Tohoku Expressway” displayed on the right screen, and the user selects and inputs “does not pass”. In this case, the process proceeds from step S29 to step S30, and the bypass path is temporarily selected as the guide path.
[0067]
Thereafter, when an instruction is input to pass through the toll road designated in step S29, the process proceeds to step S31, and there is an instruction for another screen display request in the same manner as in the processes after step S10 in FIG. (Step S32). When it is determined that there is no instruction, it is determined whether or not the vehicle has started (step S33). When the vehicle has not started yet, the process returns to step S22 and further guidance for other guidance routes is made. It is determined whether or not there is an instruction to display a block diagram, and thereafter the same operation as described above is repeated.
[0068]
Further, when there is an instruction for another screen display request in step S32, and when it is determined in step S33 that the vehicle has started, various other screen display processes corresponding to the running state and the like are performed. If it is determined in step S24 that there is no toll road confirmation guidance request, or if it is determined in step S26 that there is no specific toll road confirmation guidance request instruction, the process proceeds to step S32 and the same operation as described above is performed. repeat.
[0069]
In the above embodiment, as a result of the operation as described above, when traveling on a plurality of toll roads in one guide route, it is possible to easily confirm whether or not to use some of the toll roads. When not in use, other general roads can be easily presented.
[0070]
In addition to the above-described embodiments, the present invention can display various information such as the standard travel time of each road on the travel road detail display shown on the right screen of the divided screen of FIG. 3, for example. Information such as a travel distance as shown in FIG. 6 may be further added while the toll road confirmation guide is displayed. In addition, although the example in which the first traveling road is identified and displayed as the initial screen of the guidance route map and the block diagram in the step S7 of FIG. 2 is shown, the travel with the longest travel distance in the selected guidance route, for example It can also be implemented in other ways, such as selecting a road. Further, in addition to displaying the identification of the specific road when the user designates the specific road, the selected guide route is sequentially directed from the current position to the destination at an appropriate time interval such as 3 seconds. It is also possible to select a traveling road and automatically perform the same display as described above. Further, for general roads other than toll roads on the guide route, when the road is selected, another guide route that does not pass through this road may be presented.
[0071]
Furthermore, in the above-described embodiment, when a specific guidance route among the calculated plurality of guidance routes is identified and displayed, for example, the information is displayed so as to be identifiable by displaying in purple. Since the selected guidance route always displays a specific traveling road that can be distinguished from other traveling roads, this identification display is displayed so that the specific guiding route can be distinguished from other guidance routes. The present invention can be further implemented in various modes such as as a means.
[0072]
In the embodiment shown in FIGS. 4 to 7, whether or not to travel on a specific toll road is selected on a screen displaying one guide route selected from among a plurality of guide routes. Although an example has been shown, for example, an arbitrary guide route is selected from a plurality of guide routes as shown in FIG. 2 and displayed so as to be distinguishable from other guide routes, and traveling road information of the guide route is displayed on the same screen.
