2. Description of the Related Art Conventionally, there are known navigation devices that provide route guidance, and most of them have a function of searching for an optimum route from a current position to a destination. In addition, when making a travel plan to a destination, there are many cases where information such as where and when to pass is desired.

Japanese Unexamined Patent Publication No. 9-243382 discloses an apparatus which displays time information by superimposing it on a distance axis including a present location and a destination. That is, the current time is displayed at a predetermined position on the distance axis, and the estimated arrival time at the destination is displayed at a position corresponding to the distance from the position at the current time to the destination. Furthermore, regarding this distance axis as a time axis,
The scheduled time such as a meeting schedule is displayed at a position ahead of the destination by a predetermined time. In this way, by displaying the schedule time in association with the distance from the current position to the destination, it is possible to recognize the relationship between the distance and the time and make a travel plan.

[0004]

However, in this conventional example, the distance and time are associated with each other based on the current time and the scheduled arrival time, the schedule time is displayed, and the travel plan is only confirmed. I have no idea to deal with the change of driving plan. Therefore, it is difficult to adjust the departure time and the arrival time, and to change the schedule according to the change in the schedule time.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a travel plan creating apparatus which can easily adjust a schedule when creating a travel plan.

[0006]

The operation unit 14 may be composed of a switch fixed to a device panel on the vehicle side, or may be composed of a separate portable unit. The operation unit 14 is provided with at least a cross cursor for input.

The display 16 is composed of a color LCD (liquid crystal display) or the like. Map database 1
2. The operation unit 14 and the display 16 are all connected to the navigation ECU 10, and the navigation E
The CU 10 performs necessary processing. Also, the display 16
Prepare a touch panel on the front of the to configure the operation unit 14,
It is also preferable to be able to input data in accordance with the display.

Here, in the present embodiment, the display 1 is used when a route to a destination is searched and a travel plan is prepared.
The time schedule can be displayed at 6 and the schedule can be adjusted. This operation will be described with reference to FIG.

First, a destination point and a passing point are set (S11). These points can be set by setting their positions on the map, or can be input from various information such as addresses, telephone numbers, and facility names. As a result, the navigation ECU 10 refers to the map data in the map database 12 to search for the optimum route to the destination via the passing point. The starting point is
Basically, it is the current position, but a start point may be input to set another point.

Then, the searched route is displayed and the user is asked to confirm. If the displayed route is not preferable, the user can reset various conditions, re-search for the route, and select a route that suits his or her wish. In this way, the route calculation is completed and the route is determined (S12).

Next, the navigation ECU 10 calculates the scheduled passage time of each point (including the destination) from the current time (S13). That is, the map database 1
The distance between each point, the average traveling speed, the required time, and the like are calculated from the distance for each link, the travel time, and the like stored in 2, and the scheduled passage time of each point is calculated. Then, the estimated passing time obtained by such calculation is displayed as a time schedule together with the distance and the required time of the section (S14). In this example, an expressway interchange (IC) is automatically adopted as a passing point for calculation display.

FIG. 3 shows a display example of the time schedule displayed in S14. In this way, the time schedule 16a is shown, which shows the current position A, the passing point B, the expressway entrance interchange C, the expressway exit interchange D, the passing point E, and the destination F, and which extends horizontally in the lower part of the screen. Is displayed.

In this time schedule 16a, as shown in FIG. 4, scheduled passage times at respective points (including a start point and a destination) are listed in a bar in a time series. In particular, at each time on this one bar, each point is arranged corresponding to the distance between the points. That is, near points are close on the display, and far points are far on the display. In addition, you may arrange | position each point according to the required time between each point.

Below the bar displaying the scheduled time, a bar displaying the required section time is arranged. The bar of this section required time is arranged so that the position of each point coincides with the bar for displaying the time, and the required time is arranged between each point. Further, below the bar for the section required time, a bar indicating the section distance is displayed. The display position of each distance in the section distance bar is arranged so as to be below the required time for each section.

By displaying the time schedule as described above, not only the departure time and the arrival time to the destination but also the scheduled passage time of each passing point, the required section time including each passing point, and the section distance are known. be able to.
In particular, since each point is displayed in the bar format associated with the distance or the time, the user can grasp the entire route as a sense when he or she sees it.

Then, it is determined whether the time is changed (S1
5). The time can be changed by operating the operation unit 14 to select any scheduled time and change the scheduled time with the scheduled time selected. As shown in the upper part of FIG.
When one scheduled time is selected, a box in which the scheduled time can be changed by hour / minute is displayed, and the scheduled time can be changed. In the illustrated example, the passing time at the passing point C is changed from 8:20 to 9:10.

When the scheduled time is changed in this way, the scheduled time of each point is recalculated (S1).
6). As a result, the transit time at each point is recalculated. That is, as shown in the lower part of FIG. 4, the passing time of each point including the departure time is changed on the assumption that the passing point C is passed at 9:10. And
Returning to S14, the time schedule is updated and displayed at the recalculated scheduled time. Note that the time may be directly input by a numerical value, or various methods such as clicking an arrow can be adopted.

Then, in S15, if the time has not been changed, this process ends. As described above, according to this embodiment, the scheduled passage time of each point can be changed. Therefore, it is possible to easily adjust the travel plan in response to a request to pass this point at this time. In addition, the arrival time at the destination can be changed in the same manner, and it is possible to easily answer a request such as what time to arrive at the destination. Further, even if the schedule is changed after the travel plan is once set up, it is possible to easily deal with it.

Further, on the screen shown in FIG. 3, by operating a predetermined button displayed on the screen, the route travel section / calculation table shown in FIG. 5 is displayed. This table displays the passing points in the route from the start point to the destination, the name of the point about the highway interchange, the passing time, the required time for each section, the section distance, and the section average speed. And in this example, as shown by the arrow next to the character display in the figure,
It is possible to change the passing time of each point, the time required for the section between the points, the section distance, and the average section speed. That is, on this screen, the item can be changed by designating the changed item and entering a new numerical value here.

The change of the scheduled passage time is similar to the above case. When the section required time is changed, recalculation is performed, the scheduled passing time at the subsequent point is changed, and the corresponding section average speed is changed.

It is also possible to change the average speed on this screen. As a result, recalculation is performed, the corresponding section required time is changed, and the scheduled passage time at the subsequent point is changed.

In this way, the running form of the predetermined section can be changed to the one desired by the user. Therefore, when a plurality of drivers are driving, it is possible to set to travel slowly in a predetermined section or relatively fast according to the drivers, and it is possible to make a travel plan to the destination based on this. .

The section required time may be changed on the screen of FIG. 3 (FIG. 4), or the average speed may be displayed on the screen of FIG. 3 (FIG. 4) so that it can be changed on that screen. Good.

Further, a specific time (12:00) mark is displayed at the position of noon (12:00) on the time bar of the time schedule. As a result, it is possible to easily recognize at which point and position in the route travel the noon will occur.
Note that instead of the 12:00 mark, marks of other times may be adopted, and the user may specify the time to create the specific time mark.

The screen of FIG. 5 is provided with a "break / stop" button. By operating this button with a predetermined point selected, the break / stop time at that point can be input. Although not shown in FIG. 5, when the break / stop time is input, the break / stop time input between the display of the scheduled passage time and the required section time is displayed. The input method is the same as the above-mentioned time change and the like. Then, the scheduled time including the break / stop time is recalculated, and the scheduled passing time of the subsequent points is displayed.

Further, the estimated arrival time and the estimated departure time can be displayed for all points, and a break /
It is also preferable to calculate and display the estimated arrival time and the estimated departure time in consideration of the stop time. In this case as well, the break / stop time may be displayed. Further, it is also preferable to display both the arrival time and the scheduled departure time only when the break / stop time is set, and to display only the transit time in other cases. Further, such a setting display may be performed on the screen of FIG.

Further, it is preferable that these schedules can be adjusted and changed even after the start of route travel. As a result, if you take a break at an unscheduled point or call to change your schedule,
It is possible to respond flexibly.

Furthermore, if the vehicle cannot travel as planned and a delay occurs with respect to the travel plan, it is also preferable to change the current position mark indicating the current position of the vehicle from black to red to show it to the user. is there.

In the above example, the map database 1
The time required for the section, the estimated time of passage, etc. were calculated from the data stored in 2. However, considering the traffic congestion information obtained from beacons, FM multiplex broadcasting, traffic information centers, etc.,
It is also preferable to change the travel time for each link and calculate the time required for the section, the estimated time of passage, and the like.

[0036]

As described above, according to the present invention,
Since the scheduled passing time of points and the average traveling speed between points can be adjusted and the result after the adjustment can be viewed, the traveling plan can be easily adjusted and changed. Also, it is easy to know where you are at a specific time, which is convenient for planning.
