The 5 route screen is displayed when the user selects the 5 route button 62 on the entire route screen.
On the 5-route screen, the five routes searched by the navigation device 1 are color-coded and displayed on the map.
In the 5 route screen, a detailed button 61, an all-stroke list button 66, and a wide area button 65 are displayed at the bottom of the screen, and the user can select one from the touch panel.

FIG. 3 is a diagram showing an example of the entire process list screen displayed on the display 42 by the navigation device 1.
The all-stroke list screen is displayed when the user selects the all-stroke list button 66 on the five-route screen.
A per-hour peripheral facility button 71 and a return button 72 are displayed in the upper part of the entire process list screen, and a list of all processes is displayed in the lower area.
The list of all routes includes items of “search condition”, “all routes”, “toll road”, “charge”, and “required time”.

In the item “search condition”, a recommendation button 73, a pay priority button 74, a general priority button 75, a distance priority button 76, and another route button 77 are displayed in the vertical direction from the top.
These buttons correspond to a recommended route, a pay priority route, a general priority route, a distance priority route, and another route, respectively.
In other items, the values of the following items are displayed corresponding to the buttons of the item “search condition”.

That is, in the item “all strokes”, the distances of all the routes of each route are displayed.
In the item “toll road”, the total distance of toll roads included in each route is displayed.
In the item “charge”, the total charge of toll roads included in each route is displayed.
The item “required time” displays a time estimated to be required to arrive at the destination when traveling on each route.
In this way, on the all process list screen, the user can list the outline of each route.

The recommendation button 73 to another route button 77 are buttons for selecting these routes. When the user selects any one of the routes, the navigation device 1 sets the selected route as a guide route.
The hourly peripheral facility button 71 is a button for transitioning to the hourly peripheral facility screen.
The return button 72 is a button for returning to the 5-route screen.

FIG. 4 is a diagram showing an example of the hourly peripheral facility screen displayed on the display 42 by the navigation device 1.
The per-hour peripheral facility screen is displayed when the per-hour peripheral facility button 71 is selected on the entire process list screen.
The Hourly Peripheral Facility screens are available for each route from the recommended route to another route. The Hourly Peripheral Facility screen for the recommended route → The Hourly Peripheral Facility screen for the paid priority route → ... → Another Route For example, a peripheral facility screen for each hour can be cyclically changed by a user operation.
FIG. 4 is an hourly peripheral facility screen for the recommended route.

A recommendation button 81 is displayed at the upper left of the hourly peripheral facility screen. When the recommendation button 81 is selected by the user, the navigation device 1 sets the recommended route as the guidance route.
A time axis 86 is displayed below the recommendation button 81. The time axis 86 represents the time from when the vehicle departs until it arrives at the destination. By default, a time scale (hereinafter, scale time) is formed every 30 minutes.
Although not shown, the hourly peripheral facility screen includes scale time setting items for the time axis 86, and the user can select, for example, “every 45 minutes”, “every hour”, etc. The time can be set.
In this case, the navigation device 1 includes a time reception unit that receives a time setting, and the navigation device 1 extracts a facility using the time when the setting is received as a predetermined time.

Below the time axis 86, a mark of the facility is displayed corresponding to the time axis 86, with the time required for the vehicle to arrive at the facility as a coordinate value.
The genre of the facility to be displayed is set to a convenience store and a restaurant by default, but in addition to this, the user can arbitrarily set a gas station, a hotel, or the like.
The mark 82 represents a convenience store, the mark 83 represents a restaurant, and the mark 84 represents a destination.

The navigation apparatus 1 specifies the facility for each scale time as follows.
For example, in the case of a facility that is displayed corresponding to a scale time of 30 minutes, the navigation device 1 identifies a point that will arrive 30 minutes later on the route, and a predetermined 1 km before and after the route from the point in the facility information DB 56 Search for facilities in the range.
That is, the navigation apparatus 1 extracts facilities that are within a predetermined distance before and after the point where the scale time is reached as the required time, and displays the facilities corresponding to the scale time.
This is because the time required for a facility at a predetermined distance before and after the point where the scale time is reached is considered to be the scale time.

Alternatively, the facility corresponding to the scale time can be specified as follows.
That is, the location of each facility on the route is specified from the facility information DB 56, and the time required to arrive at each facility is calculated using the assumed vehicle speed.
The calculation of the required time to the facility uses a method of calculating the required time from the starting point to the destination by the conventional technique. That is, if the facility is assumed to be the destination, the required time from the departure place to the facility can be calculated.
Then, the required time is included within ± 5 minutes of the scale time, and the facility mark is displayed at the position of the corresponding scale time on the time axis 86.
For example, the navigation apparatus 1 extracts a facility with a required time of 25 minutes to 35 minutes, and displays the mark of the facility corresponding to a scale time of 30 minutes.

Both of the above two methods specify the facility on the searched route, calculate the required time to the facility, and the navigation apparatus 1 includes facility specifying means for specifying the facility existing on the searched route, And calculating means for calculating a time required to travel on the searched route and reach the specified facility.
In addition, although the required time calculated by the calculation is determined to the unit of minutes and seconds, the actual vehicle speed is generally different from the vehicle speed used in the calculation, and the required time may be approximate, so the navigation device 1 The time required for the facility is rounded to the scale time.

The detailed information button 85 is a button that is selected when referring to the detailed information of the facility displayed corresponding to the scale time of 30 minutes.
A detailed information button is similarly provided for facilities of other scale times such as 90 minutes and 120 minutes.
The pay priority button 87 is a button that is selected when transitioning to the per-hour peripheral facility screen for the pay priority route.

Thus, on the hourly peripheral facility screen, the user can grasp at a glance how the facilities are distributed along the time axis 86.
Further, when the time axis 86 is long and cannot be displayed on one screen, the navigation device 1 displays a scroll button in the area 88 so that the screen can be scrolled.

In addition, on the peripheral facility screen for each hour, the facility mark is displayed in association with the time axis 86. Therefore, the navigation apparatus 1 uses the facility information (marked by the mark) of the facility identified as being on the searched route. The display means displays the details in a separate screen in association with the required time calculated for the facility, and the display means displays the required time as a coordinate value. Thus, the specified facility information is displayed on the time axis (time axis 86).
In addition, since the navigation device 1 extracts and displays the facility corresponding to the scale time, the navigation device 1 selects a specified facility whose required time calculated for the facility is a predetermined time. Extraction means for extracting is provided.

FIG. 5 is a diagram illustrating an example of a per-hour peripheral facility screen for a pay priority route.
The hourly peripheral facility screen for the pay priority route is displayed when the pay priority button 87 is selected on the hourly peripheral facility screen for the recommended route (FIG. 4).
The configuration of the hourly peripheral facility screen for the pay priority route is the same as the hourly peripheral facility screen for the recommended route.

When the user touches and selects the pay priority button 91, the navigation device 1 sets the pay priority route as the guide route.
In addition, when the user touches and selects the general priority button 92, the navigation device 1 transitions to the general priority hourly peripheral facility screen.
The configuration of the peripheral facility screen for each hour for the general priority route, the distance priority route, and another route is the same.

FIG. 6 is a diagram showing an example of the facility detail genre screen, which is displayed on the display 42 by the navigation device 1 when the user touches and selects the detailed information button 85 (FIG. 4).
On the facility detail genre screen, a scale time display unit 94, scroll buttons 95 and 96, a genre button area 97, and the like are displayed.
The scale time display unit 94 displays the scale time of the detailed information button 85 (FIG. 4) selected by the user.
The scroll buttons 95 and 96 are buttons for touching when scrolling the screen up and down, respectively.

In the genre button area 97, the genre of the mark displayed corresponding to the scale time is displayed so as to be selectable by the genre button.
When the user selects the genre button, information on stores belonging to the genre is displayed.
Thus, on the facility detailed genre screen, the genre of the facility corresponding to the detailed information button selected by the user on the peripheral facility screen for each hour is displayed in a list.

FIG. 7 is a diagram showing an example of the facility detail store screen, which is displayed on the display 42 by the navigation device 1 when the user selects a restaurant in the genre button area 97.
On the facility detail store screen, a mark 100 of the selected genre, scroll buttons 95 and 96, a store button area 101, and the like are displayed.
The scroll buttons 95 and 96 are buttons for touching when scrolling the screen up and down, respectively.

In the store button area 101, store buttons of stores belonging to the genre selected by the user are displayed so as to be selectable.
In FIG. 7, since the restaurant is selected, the store buttons of the restaurant such as “gyudondong” and “Yamanaka restaurant” are displayed to be selectable.
When the user selects any store button, the navigation device 1 displays more detailed information for the store.

FIG. 8 is a diagram showing an example of the facility detail guidance screen, which is displayed on the display 42 by the navigation device 1 when the user selects “gyudondon” in the store button area 101 of FIG. 7.
On the facility detail guidance screen, for example, detailed information on the store such as store introduction, menu, business hours, and the like is displayed.
Although not shown, each screen of FIGS. 6 to 8 is provided with a return button so that it can return to the screen before the transition.

FIG. 9 is a flowchart for explaining an overall procedure in which the navigation device 1 performs route guidance processing.
The processing of the navigation device 1 described with reference to the flowcharts of FIG. 9 and thereafter is performed by the CPU 21 (FIG. 1) according to a predetermined program.
Although not shown, the navigation device 1 can display a destination setting screen for receiving information for specifying the destination such as an address, a telephone number, and a zip code from the user. A destination is determined (step 5).

Next, the navigation device 1 specifies the current position using the GPS signal received by the GPS receiver 14 (FIG. 1).
Then, the navigation device 1 searches for a route from the current position to the destination using the node data file 53 or the like (step 10).
The navigation device 1 performs this route search for five routes including a recommended route, a pay priority route, a general priority route, a distance priority route, and another route.
The algorithm used for these five route searches can use what was used conventionally.

  Next, the navigation device 1 searches the facility information DB 56 for facilities on the searched route for each route. Then, the time required to arrive at the searched facility is calculated for each facility, and peripheral facility data is generated for each hour (step 15).

Next, the navigation device 1 performs a route selection process for receiving a user's route from an all-stroke list screen (FIG. 3), an hourly peripheral facility screen (FIG. 4, etc.), etc. (step 20).
Then, the navigation device 1 performs guidance processing for the route selected by the user (step 25).
The guidance process can use a conventional method.

FIG. 10 is a flowchart for explaining the procedure of the hourly peripheral facility data generation process in step 15 (FIG. 9).
First, the navigation device 1 identifies one route (for example, a recommended route) among the five routes (step 50).
Next, the navigation device 1 specifies a point that arrives every 30 minutes from the departure point (that is, every graduation time) on one route (step 55).

The navigation device 1 stores, for example, an estimated value of the traveling speed between the nodes constituting the route and an estimated traveling speed when traveling on each road in the other data file 57 in advance. Can predict the arrival point every 30 minutes.
Alternatively, the current road condition broadcast distributed by the server device may be received using the data transmission / reception device 16 (FIG. 1) and calculated using this.

Next, the navigation device 1 specifies a 1 km front and rear range along the route from the specified point as a facility search range (step 60).
In the present embodiment, the facility search range is 1 km before and after the route from the specified point. However, various range setting methods are possible, for example, a circular region with a predetermined radius centered on the specified point. Alternatively, a rectangular region having a predetermined length in the route direction and a predetermined length in a direction perpendicular to the route centering on the identified point can be formed.

Next, the navigation device 1 extracts, for each identified point, a facility whose location is the facility search range among the facilities in the facility information DB 56 (step 65).
Then, the navigation apparatus 1 generates hourly peripheral facility data by associating the searched facility with the scale time (step 70).
That is, the facility searched for the scale time of 30 minutes corresponds to the scale time of 30 minutes, and the facility searched for the scale time of 1 hour corresponds to the scale time of 1 hour.
The navigation device 1 performs the above processing for all five routes.

FIG. 11 is a flowchart for explaining the procedure of the route selection process in step 20 (FIG. 9).
First, the navigation apparatus 1 accepts the selection of the all-stroke list button 66 on the five-route screen (FIG. 2B), and displays the all-stroke list screen (FIG. 3) (step 105).

When the per-hour peripheral facility button is selected on the entire process list screen (step 110; Y), the navigation device 1 displays the per-hour peripheral facility screen (FIG. 4, 5, etc.) (step 115), Accept selection.
On the other hand, when the recommendation button 73 to another route button 77 is selected on the all-stroke list screen (step 110; N), the navigation device 1 accepts selection of a route corresponding to the button.
In this way, when the navigation device 1 accepts the selection of the route by the hourly peripheral facility screen or the recommendation button 73 to the different route button 77, the route detailed information screen showing the detailed information of the route is displayed, although not shown. (Step 120).

According to the embodiment described above, the following effects can be obtained.
(1) The location of the facility can be represented by a time axis based on travel time.
(2) When determining a stop point before the start of driving, such as setting a break point during driving, it is possible to perform a search based on travel time, such as a facility that arrives after several hours.
(3) Since the facility search can be performed based on the travel time, the facility search and the route selection according to the user time interval can be performed.
(4) When selecting 5 routes, not only the route information such as the time and distance shown in the list of all routes, but also the information about what kind of facilities exist after a predetermined time when the route is selected. be able to.

Next, a modification of the hourly peripheral facility screen will be described with reference to FIG.
In the present embodiment described above, it was necessary to switch the screen cyclically every five routes, such as for recommended routes → for paid priority routes →... In the lower part of the screen, a recommendation button 111, a pay priority button 112, a general priority button 113, a distance priority button 114, and another route button 115 are listed, and the user can directly select a desired one by selecting these buttons. You can transition to the screen.

Then, among the recommended buttons 111 to the different route buttons 115, the one selected by the user is changed in display state such as a display color so that it can be identified from other buttons.
When the button is selected again with the display state changed, the navigation device 1 recognizes that the route of the button has been selected.
Thus, in this modification, the user can directly select the peripheral facility screen for each hour of the desired route out of the five routes.

FIG. 13 is a diagram for explaining another modification of the hourly peripheral facility screen.
On the hourly peripheral facility screen according to this modification, a list of time axes 131 to 135 of the recommended route to another route displaying the facility is displayed.
However, since facilities cannot be displayed on one screen when represented by marks, they are displayed in an abbreviated shape such as a triangle mark.

On the left side of the time axes 131 to 135, a recommendation button 121, a pay priority button 122, a general priority button 123, a distance priority button 124, and a separate route button 125 corresponding to each time axis are displayed in a list. When one of these is selected, the navigation device 1 transits to a route-specific peripheral facility screen (for example, FIG. 4) for the route specified by the button.
Thus, in this modification, the user can view a list of temporal distributions of facilities on each route.
As described above, in this modification, the navigation device 1 searches for a plurality of routes, and displays facility information of each route on the time axis so that the facility information of which route can be identified. .
