It is superimposed and displayed, and the map image is scrolled or displayed according to the movement of the vehicle. 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, a DVD-ROM, or a hard disk is divided into appropriate longitude and latitude widths according to various scale levels. Are stored as a coordinate set of nodes represented by longitude and latitude. A road is composed of a connection of two or more nodes, and the map data displays a road layer including a road list, a node table and an intersection configuration node list, and roads, buildings, facilities, parks, rivers, and the like on a map screen. Data for displaying characters, map symbols, etc., such as administrative division names such as municipal names, road names, intersection names, and facility names.
[0004]
In addition, this navigation device has a route guidance function for allowing a user to easily travel to a desired destination without making a mistake on a road. According to the route guidance function, a destination or a stopover is set by various means using an address, a telephone number, scrolling of a map, a nearby landmark, and the like, and a route connecting these points from the departure point to the destination is provided. Among them, an appropriate route is calculated and presented in consideration of various conditions. In addition, the route selected by the user is stored as a guidance route, and during traveling, the guidance route is displayed on the map image in a different color from the other routes and is drawn thicker, or the vehicle is displayed on the guidance route. When approaching the intersection where the course should be changed within a certain distance, the intersection is enlarged and displayed, and an arrow or the like indicating the direction in which the course should be changed is drawn and displayed on the screen, or voice guidance for turning right or left is performed. This allows the user to be guided to the destination.
[0005]
In calculating the above-mentioned guidance route, for example, various routes such as a route that can arrive from the current location to the destination in the shortest time, a route that travels the shortest distance, a route that uses or does not use an expressway or another toll road, and the like. The calculation is performed by the route calculation method of the embodiment, and each is displayed on the map in a different color. At this time, for example, as shown in FIG. 8 (a), the guidance route is superimposed and displayed on a reduced-scale map that can display the current position P to the destination M on one screen, so that the user can go to the next place. A guidance route confirmation map is displayed so that the user can grasp the entire route.
[0006]
A plurality of guidance routes R1 to R3 from the current location P to the destination M calculated as described above are displayed in this guidance route confirmation map screen in a different color as appropriate, and whether the route to be selected is appropriate is determined. Checks can be made. At this time, when the user does not like the selected route or the recommended route displayed in a predetermined color such as purple, the user can select another route on a menu screen or the like.
[0007]
Further, it is unclear what road the selected route actually travels depending on the map display, and when the user wants to know more detailed information on the traveling road, the details of the road are displayed on a menu screen or the like. By selecting the display, for example, a section diagram showing detailed information of the traveling road as shown in FIG. 8B can be displayed. In the illustrated example, when the user travels on the guide route R1 of FIG. 8A, the user first travels 2 km on a general road and enters National Highway 6, and after traveling 32 km on this road, enters the Shin-Otone Bridge Road. It is shown that after traveling 6 km, it enters National Highway 294, after traveling 10 km, it enters Prefectural Road 354, and when it travels 2 km, it reaches its destination. It is possible to confirm 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 was necessary to switch to the detailed display of the traveling road as shown in FIG.
For this reason, in the traveling road detailed information display section diagram screen, for example, in the guidance route displayed on the guidance route confirmation map screen, which road portion is the Shin-Otone Bridge road and is the national highway 294 Without knowing, it was necessary to display the actual driving map screen to check the road name and the like, which was troublesome.
[0009]
Further, by confirming whether or not the selected guidance route is appropriate by displaying the traveling road detailed information as shown in FIG. 8B, it is determined that the selected guidance route is not a preferable route due to the user's experience and the like. If 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 operate the menu screen etc. again. It was necessary to display the detailed information on the traveling road and perform the same confirmation, which was troublesome.
[0010]
In addition, when the guidance route is displayed and the guidance route travels on a toll road such as an expressway, the user performs the traveling road detailed information display on the guidance route as described above and confirms the traveling on the toll road. If the user confirms that the toll road is a single toll road and the traveling distance is relatively short, the user can easily search for a road that runs only on a general road that does not use the toll road, thereby easily searching for the toll road. Another guidance route that does not use a toll road can be obtained, and a comparison with the case of using a toll road can be made.
[0011]
However, the initially presented guidance route travels on a plurality of toll roads such as expressways, and the traveling distance of one of the toll roads is relatively short. If you know by switching to, it is extremely difficult to set search conditions to search for a guidance route that does not travel only on that toll road, and it takes a lot of trouble, so after all you often travel with that guidance route Become. In doing so, they had to travel on short toll roads at relatively high prices, especially when considering the route, when there was an appropriate general road that bypassed the toll road. When the user knows, 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 the guidance route is easily associated with the guidance route confirmation map screen. Confirmation can be performed, and the same confirmation can be easily performed for other guidance routes. When there are multiple toll roads in the guidance route, some of the toll roads are used. It is a main object of the present invention to provide a navigation device which can easily confirm whether or not to perform the operation, and can easily present another road when not in use.

In the navigation device having the functional block diagram as described above, the screen display processing of the guidance route performed by the guidance route display processing unit 1 of FIG. 1 is sequentially performed according to, for example, an operation flow illustrated in FIG. Can be made. Hereinafter, the operation flow of the first embodiment of the guidance route screen display processing 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 input of the current location, which is the basic data for calculating the guidance route at first (step S1), and the setting of the destination and the waypoint as necessary are performed (step S1). Step S2). The input of the current location can usually be performed by taking in the GPS signal of the navigation device. When setting the destination or the waypoint, the scrolling of the map, the input of the address, the input of the nearby station name which have been widely performed in the past are performed. The user can make settings by employing various means such as inputting a telephone number and inputting the data.
[0035]
Next, the navigation device calculates the guidance route based on conditions such as expressway priority or non-priority, shortest distance, and minimum required time (step S3). At that time, even when the user gives an instruction such as expressway priority in advance, taking into account that later presentation of another route is required, calculation of a guide route in another mode is performed, and the respective data is calculated. Ask.
[0036]
Next, in the calculation of the guide route, it is determined whether or not a user has input a priority instruction such as a highway priority (step S4). When it is determined that the user has input a priority instruction, the display screen is displayed, for example, as shown in FIG. As shown in the figure, it is divided into two parts on the left and right. In the illustrated screen example, all the calculated guidance route diagrams are displayed on the left side as one side. Is displayed so as to be identifiable (step S5). The display screen can be divided by the guidance route confirmation screen division instructing unit 11 in FIG.
[0037]
The screen example shown in FIG. 3 shows an example in which all three calculated guidance 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 same drawing, the guide route R1 is a priority instruction guide route or a recommended guide route to be described later, and the other guide route R2 is green, the guide route R3 is pink, or the like. The guidance route R1 is displayed so as to be easily distinguishable from other guidance routes, such as being displayed in purple as a predetermined specific color different from the color. The process of displaying all the guidance routes on one screen is performed by the entire guidance route display unit 20 in FIG. 1, and the process of identifying and displaying the guidance route designated by priority is performed by the selected guidance 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 based on a signal that the guidance route calculation unit 5 detects that the calculation in the guidance route calculation unit 5 has been completed in the guidance route calculation completion detection unit 12 in FIG. The determination can be made by detecting whether or not the user has performed a priority instruction input from the instruction signal input unit 6 with the guidance route selection unit 13.
[0039]
Next, a block diagram showing detailed information of the guidance route instructed by priority 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 S6). In the example of the screen shown in FIG. 3, since the guidance route R1 is the guidance route for which the priority instruction has been given as described above, information on the traveling road as detailed information on the guidance route R1 is displayed. In the illustrated example, as in the conventional example shown in FIG. 8, first drive on a general road for 2 km to enter National Highway No. 6, then drive for 32 km, then enter Shin-Otone Bridge Road and drive for 10 km. After that, you enter National Highway 294, drive 6km here, then enter Prefectural Road 354, and drive 2km here to reach your destination. The display of the block diagram of the priority instruction guide route in step S6 can be performed by the selection signal of the identification guide route selection unit 13 in the block diagram display unit 18 in FIG.
[0040]
On the other hand, if it is determined in step S4 that there is no priority instruction input, the display screen is first divided into two in the same manner as in step S5, and in the illustrated embodiment, all the calculated guidance route diagrams are displayed on the left side as one side. Then, a 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 illustrated in FIG. 3, when there is no priority instruction input as described above, when the navigation device sets the guide route R1 as a recommended guide route, the guide route R1 is set to a predetermined specific color such as purple. It is displayed in a color, different from the display color of the other guidance routes, and displayed so as to be easily distinguishable therefrom. Note that such identification display processing of a specific guidance route is performed in the selected guidance route identification display unit 21 in FIG.
[0042]
Next, similarly to the step S6, the section diagram 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 screen example shown in FIG. 3, an example is shown in which the guide route R1 is set as a recommended guide route when the above-described priority instruction does not exist, and the guide route R1 is used as detailed information as described above. Information about the driving road is displayed. The display of the section map is performed by the selection guide route section diagram display section 23 in FIG.
[0043]
In the example shown in FIG. 2, an example is shown in which, after the end of step S6 or step S12, the first traveling road that the vehicle travels first when the vehicle travels from the current position is identified and displayed in the guidance route diagram and the block diagram. (Step S7). The road to be selected at this time may be set to any road, but when the first road is displayed, the user can immediately know the information of the road on which the user first runs. The above-described traveling road identification processing can be performed by the selected traveling road identification display unit 22 for the guide route map, and can be performed by the selected traveling road division diagram identification display unit 24 for the section map.
[0044]
Next, it is determined whether or not there is a user's request to confirm a section map of another traveling road in the guidance route (step S8). This determination can be made by detecting whether or not the user has input a block diagram confirmation request for another traveling road from the instruction signal input unit 6 in the identification traveling road selecting unit 14 in FIG. When the user inputs a block diagram confirmation request for another traveling road, for example, the user inputs a signal of operating the joystick of the remote controller in the front-rear direction in the state shown in FIG. Input can be performed by moving the colored display frame vertically in the figure and displaying it.
[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 designated by the user is identified and displayed in the guidance route diagram and the section map (step S13). . The screen example shown in FIG. 3A shows an example in which the user selects and instructs the next road after the identification of the first traveling road as the initial screen as described above. In the guidance route diagram 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 is shown in which the traveling road L is easily distinguishable from other traveling roads.
[0046]
In the block diagram displayed on the right side of the divided screen, the display frame of National Highway No. 6 where the road information on this driving road L is shown is surrounded by a bold line, and the inside of the display frame is colored and displayed with other driving roads. Shows an example in which the information is displayed so that it can be easily identified. This makes it possible to easily know which part of the specific traveling road in the guidance route corresponds to, for example, National Route 6 in the guidance route diagram. After the end of step S13, the process returns to step S8, and waits for an instruction for a request for displaying detailed information on another traveling road.
[0047]
In the screen example shown in FIG. 3B, the user again operates the joystick of the remote control in the front-rear direction from the state shown in FIG. An example is shown in which it is displayed whether a part corresponds to a part. As a result, in the block diagram, the thick frame for identification display and the colored portion in the frame move from “National Route 6” in FIG. 3A to “Shin-Otone Bridge Road” in FIG. 3B. Similarly, in the guidance route diagram displayed on the left side, as shown in FIG. 3 (b), the road portion L traveling after the "National Route 6" on the same guidance route R1 is indicated by a thick line or the like. Displayed with.
[0048]
When it is determined in step S8 that there is no instruction to request a block diagram of another traveling road in the selected guidance route, it is then determined whether there is an instruction to display a block diagram of another guidance route (step S9). . This determination can be made in the same manner as described above by detecting whether or not an instruction signal has been input to the discriminative guidance route selection unit 13 in FIG. As a result of this determination, when it is determined that there is an instruction to display a block diagram of another guide route, a block diagram indicating travel road information as detailed information is displayed for the instructed guide route (step S14). Thereafter, the process returns to step S7, in which the guidance route and the first traveling road on which the current location traveling is started in the block diagram are identified and displayed as an initial screen in the display of the guidance route so as to be easily distinguished from the others. Repeat the operation.
[0049]
When it is determined in step S9 that there is no instruction to display a block diagram of another guide route, it is determined whether or not there is an instruction for another screen display request (step S10). Another screen display requested is performed (step S16). Here, when the other screen display request instruction is a display request instruction of a driving guidance route, a map screen centered on the own vehicle position displayed during normal driving and a process as described above are displayed on the map. The guidance route finally confirmed is displayed as a guidance route selected by the user. Whether or not such a driving guidance route display request instruction is present is determined by whether or not the user has performed an input from the instruction signal input unit 6 using the traveling guidance route display instruction input unit 16 in FIG. Can be detected.
[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). When it is determined that is, the process proceeds to step S16, and another screen display is performed in the same manner as described above. When it is determined in step S15 that the vehicle has not yet departed, the process returns to step S8, and further determines whether or not there is an instruction to confirm a block diagram of another traveling road and performs subsequent processing on another screen. Repeat until a display request or departure of the vehicle.
[0051]
The navigation device as described above differs from the navigation device shown in FIG. 8A in that it is displayed on a separate screen, like the detailed display of the conventional guidance route shown in FIG. Since the information is displayed on the screen in association with each other, detailed information of each guidance route can be easily and reliably known. Furthermore, it is possible to see at a glance which traveling road on the guidance route corresponds to the traveling road specified by the user on the guidance route, and a function that cannot be performed by the conventional navigation device is added. It is possible to do.
[0052]
On the other hand, the function as described above in the present invention is also effective when a plurality of toll roads are present in a guidance route, and when a guidance route that travels on a general road bypassing a specific toll road among them is effectively provided. Can be used. The embodiment for performing the function can be implemented by a navigation device including the functional block shown in FIG. 4 in which other functions are added to the function shown in the functional block diagram of FIG. 1, for example. The guide route screen display processing in the above can be sequentially operated, for example, according to the operation flow shown in FIG. Hereinafter, this embodiment will be described.
[0053]
In the navigation device having the functional blocks shown in FIG. 4, a toll road bypass calculation instruction unit 19 is added to the guidance route display processing unit 1 in addition to the navigation device shown in FIG. , A toll road travel confirmation display unit 26 is added to the guidance route diagram display unit 17, and a toll road travel confirmation selection input guidance display unit 27 is further added to the block diagram (information) display unit 18.
Also, functional blocks that perform the same functions as the functional blocks in the navigation device shown in FIG. 1 are given the same names and the same numbers, and therefore detailed descriptions thereof are the same as those described above, and thus description thereof is omitted here. .
[0054]
In the toll road travel confirmation display unit 26 in the guidance route confirmation display unit 17, the display of the guidance route diagram is performed to confirm whether or not the selected guidance route travels on each toll road for each toll road. By utilizing the function of the road identification display unit 22, the information is displayed on one side of the monitor screen so as to be identifiable for each guidance route. At this time, the toll road bypass calculation instruction unit 19 instructs the guidance route calculation unit 5 to calculate the guidance route of the general road that bypasses the toll road specified by the user for the toll road.
The toll road travel confirmation display unit 26 performs a process of adding and displaying the resulting guidance route of the bypass road to the previous guidance route, and traveling on the toll road or traveling on the bypass road. It is possible for the user to easily determine whether or not. As described above, the guide route calculation unit 5 performs the road that bypasses the toll road designated by the user according to the instruction of the toll road bypass calculation instruction unit 19, so that the guidance route calculation unit 5 at this time is charged. It functions as road bypass calculation means.
[0055]
At this time, in the selected traveling road information display section 24, for each toll road displayed on the toll road traveling confirmation display section 26, the names of the toll roads and the like are displayed so that the correspondence with the toll roads can be easily understood. It also performs the function of displaying information on the same screen. Further, the toll road travel confirmation selection input guide display unit 27 is used to input a selection of whether to travel on the toll road or on the bypass road on the same screen as the above-described guide route diagram. The guidance display is performed.
[0056]
In the navigation device configured with such functional blocks, a user travels on a general road that bypasses a specific toll road and on the toll road on a guidance route diagram displayed on one side of a monitor screen. While comparing with the case, it is further necessary to refer to the toll road information displayed on the other side of the monitor screen by the selected traveling road information display unit 24 in the block diagram (information) display unit 18 to travel any route. By judging whether or not the selection is appropriate and performing selection and input in accordance with the selection input guidance display displayed on the block diagram display screen, it is possible to easily perform these selection displays.
[0057]
The navigation device having the functional blocks as shown in FIG. 4 can perform the screen display processing of the guidance route 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 processing shown in FIG. 5 will be described with reference to the functional block diagram shown in FIG. 4 and the screen display examples in FIGS. 6 and 7. As shown in step S21, the operation flow shown in FIG. 5 is shown as an operation flow that is performed continuously from step S6 and step S12 of the operation flow in FIG. 2, and after the operation of those steps, the division of another guidance route is performed. It is determined whether there is a figure display instruction.
[0058]
That is, the guidance route is calculated in a state where the guidance instruction of the guidance route is input in step S6 of FIG. 2, and after performing the process of displaying the identification of the guidance instruction route and displaying the section map on one screen, or In step S12, the guide route is calculated in a state where the guide route priority instruction has not been input, and after performing the identification display of the recommended guide route by the navigation device and the process of displaying the section map thereof on one screen, the user performs the process described above. Then, it is determined whether or not an instruction to display detailed information of a guidance route other than the guidance route automatically identified and displayed has been performed (step S22). Here, when the user wants to display a section map of another guidance route, a selection instruction is given by pointing the guidance route with a cursor or the like, and in that case, the section of the guidance route designated by the user is provided. A figure is displayed (step S23).
[0059]
In the above state, for example, as shown in FIG. 6A, three guidance routes from the current location P to the destination M are searched for R4, R5, and R6, and these are displayed on the left side of the screen, and a specific one of them is specified. Is selected, and a block diagram showing detailed information on the guidance route is displayed on the right side of the screen. The state of this display is substantially the same as that of FIG. 3 (a), but in FIG. 3 (a), a specific road in the selected guide route is distinguishable from other roads of the same guide route. Although the displayed example is shown, the example shown in FIG. 6 (a) shows an aspect in which at this stage, the function of displaying a specific road in the selected guide route so as to be further identifiable is not performed. ing. Therefore, in this state, the selected driving road identification display unit 22 in the guidance route confirmation display unit 10 in FIG. 4 and the selected driving road information display unit 27 in the block diagram (information) display unit 18 do not function.
[0060]
After the processing in step S23, when it is determined in step S22 that there is no instruction to display a block diagram of another guide route, that is, the guide displayed so as to be distinguishable from the other guide route on the current monitor screen. When it is determined that the display of the block diagram displaying the information of the guide route is 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. 6A, an instruction input unit for “toll road confirmation guidance” is provided, and the user inputs an instruction as shown in FIG. It can be performed by detecting whether or not it has occurred.
[0061]
Here, when it is determined that there is a toll road confirmation guidance request, that is, when it is determined that the instruction input of the toll road confirmation guidance has been performed as shown in FIG. Is displayed so as to be identifiable (step S25). In this case, for example, as shown in the guide route diagram on the left screen of FIG. 7A, regarding the guide route R5 selected in FIG. Each guide route is displayed so as to be identifiable from the others, and information on what kind of toll road each road is displayed as a block diagram on the right screen adjacent to the screen.
[0062]
The example shown in FIG. 7 shows a state in which the vehicle travels on the "Tohoku Expressway" and "Metropolitan Expressway", and is displayed so that the correspondence between the guidance route diagram portion and the block diagram portion can be easily understood. are doing. As described above, for a plurality of toll roads on one guide route, the function of displaying each road so that it can be distinguished from other roads and displaying information such as the name of each road in association with the guide route check function This can be performed in the selected driving road identification display unit 22 of the display unit 10 and the selected driving road information display unit 24 of the block diagram (information) display unit 18. Therefore, the selected traveling road identification display section 22 can be referred to as a selected toll road identification display section, and the selected traveling road information display section 22 can also be referred to as a selected toll road information display section.
[0063]
Next, for the specific guidance route displayed in this way, it is determined whether or not there is a guidance request request for a specific toll road in the specific guidance route (step S26). For this determination, for example, the cursor is moved to any of the information display and selection instruction sections of “Tohoku Expressway” and “Metropolitan Expressway” displayed on the block diagram side in FIG. FIG. 2B shows an example in which a confirmation guidance request instruction for "Tohoku Expressway" is issued.
[0064]
In particular, in the example shown in FIG. 7, the section traveling on the Tohoku Expressway is particularly short, and as shown in FIG. 6, the guidance route for traveling on this toll road is displayed even though it is only 4 km, and many users In this case, we want to know a general road that bypasses only the Tohoku Expressway. In such a case, it has conventionally been extremely difficult to search for a road that bypasses only this portion. However, in this embodiment, a specific toll road is specified separately from other toll roads as described above. Therefore, it is possible to easily input a condition for not traveling on the toll road, and to easily obtain a guide route of a general road that bypasses the condition.
[0065]
Next, a general road that bypasses the toll road indicated in the guidance route map is calculated and displayed (step S27). In addition, a selection input guidance screen for allowing or not passing 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 whichever comes first. The state after these processes is shown in FIG. 7 (b), where a "bypass road" bypassing the "Tohoku Expressway" is shown as shown on the left screen in the figure, and a section for displaying information on the road is displayed. On the diagram side, a screen for pop-ups or the like is displayed, on which the user refers to this bypass road and selects and enters whether or not to go through the specific Toll Road "Tohoku Expressway" I do. Note that when searching for a road that bypasses such a specific toll road, a route or the like that travels on a general road halfway to another toll road may be eventually displayed.
[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 shown in FIG. 7B, this determination is made by the user selecting and inputting “do not pass” according to the selection input guide screen as to whether to pass or not go through “Tohoku Expressway” displayed on the right screen. The process proceeds from step S29 to step S30, where the bypass is temporarily selected as a guidance route.
[0067]
Thereafter, the process proceeds to step S31 together with the instruction input for passing through the designated toll road in step S29, and there is another screen display request instruction as in the process after step S10 in FIG. It is determined whether or not the vehicle has departed (step S32). If it is determined that there is no instruction, it is determined whether or not the vehicle has departed (step S33). If it has not yet departed, the flow returns to step S22 to return to another guidance route. It is determined whether or not there is an instruction to display a block diagram, and the same operation as described above is repeated.
[0068]
Further, when there is an instruction of 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 according to the traveling state and the like are performed. When it is determined in step S24 that there is no guidance request for toll road confirmation, and when it is determined in step S26 that there is no confirmation guidance request instruction for a specific toll road, 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 performing the above-described operation, when traveling on a plurality of toll roads in one guidance route, it is possible to easily confirm whether or not to use some of the toll roads. , It is possible to easily present another general road when not in use.
[0070]
According to the present invention, in addition to the above embodiments, various types of information such as a standard driving time of each road can be further displayed on the driving road detail display shown on the right side of the divided screen in FIG. During the display of the toll road confirmation guidance, information such as the traveling distance as shown in FIG. 6 may be further added. Further, the example in which the first traveling road is identified and displayed as the initial screen of the guidance route diagram and the block diagram in step S7 of FIG. 2 has been described. The present invention can be implemented in other modes, such as selecting a road. Further, in addition to displaying the identification of the traveling road when the user instructs the specific traveling road, the selected guidance route is sequentially moved from the current position to the destination at appropriate time intervals such as 3 seconds. It is also possible to select a traveling road and automatically perform the same display as described above. Further, for a general road other than the toll road on the guidance route, when that road is selected, another guidance route that does not pass through this road may be presented.
[0071]
Furthermore, in the above-described embodiment, when a specific guidance route is identified and displayed among a plurality of calculated guidance routes, an example is shown in which identification is performed by, for example, displaying in purple or the like, but as described above. Since the selected guidance route is always displayed so that a specific traveling road can be distinguished from other traveling roads, this identification display is displayed so that the specific guidance route can be distinguished from other guidance routes. The present invention can be further implemented in various aspects, such as being used as a means.
[0072]
Further, in the embodiment shown in FIGS. 4 to 7, the selection as to whether or not to drive on a specific toll road is made on a screen displaying one guidance route selected from a plurality of guidance 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 travel road information of the guide route is displayed on the same screen. , And a specific road in the guidance route is displayed so as to be distinguishable from other roads, and the information display of the road is also displayed there in a state where it is also displayed as distinguishable from other roads. A display as shown in FIG. 6B for selecting whether or not to travel on the toll road may be set to be displayed on this screen by a pop-up display or the like.
