2. Description of the Related Art Conventionally, navigation devices for performing route guidance are known, and many of them have a function of searching for an optimal route from a current position to a destination. Also, when making a travel plan to a destination, it is often desired to obtain information such as where and when to pass.

[0003] Japanese Patent Application Laid-Open No. 9-243382 discloses a technique in which time information is superimposed and displayed on a distance axis including a current position and a destination. That is, the current time is displayed at a predetermined position on the distance axis, and the expected destination arrival time is displayed at a position corresponding to the distance from the current time position to the destination. Furthermore, this distance axis is regarded as a time axis,
A schedule time such as a scheduled meeting is displayed at a position a predetermined time ahead of the destination. Thus, 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 the 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 confirmed. Has no idea of responding to changes in travel plans. Therefore, it is difficult to adjust the departure time or the arrival time, or to change the schedule according to the change in the schedule time.

[0005] 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 creation device that can easily adjust a schedule when creating a travel plan.

[0006]

According to the present invention, there is provided a schedule display means for displaying scheduled departure or arrival times for a plurality of points including at least a starting point and a target point in an order along a traveling route according to a traveling plan. And time change means for changing the scheduled time of any point, readjustment means for re-adjusting the travel plan based on the changed point scheduled time, and for each point based on the readjusted travel plan. A redisplay means for redisplaying the scheduled time;
It is characterized by including.

As described above, the scheduled times are displayed in the order along the traveling route. Therefore, the user can easily know where and when he / she is going to arrive, making it easy to make a travel plan. Then, the scheduled time for an arbitrary point can be changed, and in accordance with this change, the scheduled times for other points are also changed and displayed. Therefore, the adjustment of the plan can be easily performed. For example, the plan can be easily adjusted in response to a request, such as when to reach this point.

The present invention also provides schedule display means for displaying scheduled departure or arrival times for a plurality of points including at least a starting point and a target point in an order along a traveling route according to a traveling plan. Speed changing means for changing the average traveling speed between points; readjustment means for re-adjusting the traveling plan based on the average traveling speed between the changed points; and for each point based on the re-adjusted traveling plan. Redisplay means for redisplaying the scheduled time. In this way, by adjusting the average speed, it is possible to set the traveling in the section to a desired one and to make an overall traveling plan.

The route search at 0 is performed by an optimal route search based on a linear plan, but a search with priority on a general road or a highway can be performed.

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

The display 16 comprises 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. The display 16
Prepare a touch panel on the front of the to configure the operation unit 14,
It is also preferable that data can be input in accordance with the display.

In this embodiment, when searching for a route to a destination and making a travel plan, the display 1 is used.
6, a time schedule can be displayed 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 determined and set on the map, or input from various information such as addresses, telephone numbers, and facility names. Thus, the navigation ECU 10 refers to the map data in the map database 12 and searches for the optimal route to the destination via the passing point. The starting point is
Basically, it is the current position, but it is also possible to input a start point and set another point.

Then, the searched route is displayed and the user is asked for confirmation. When the displayed route is not preferable, the user can re-search for the route by resetting various conditions, and can select a route that meets his or her wish. Thus, 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
Based on the distance, travel time, and the like for each link stored in 2, the distance between the points, the average traveling speed, the required time, and the like are calculated, and the estimated time of passage 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, the interchange (IC) of the highway is automatically adopted as a passing point as a passing point.

FIG. 3 shows a display example of the time schedule displayed in S14. As described above, the route indicating the current position A, the passing point B, the highway entrance interchange C, the highway exit interchange D, the passing point E, and the destination F is shown, and the time schedule 16a extending horizontally in the lower part of the screen is shown. Is displayed.

In the time schedule 16a, as shown in FIG. 4, scheduled passing times of each point (including a start point and a destination) are described in a bar in time series. In particular, at each time in this one bar, each point is arranged corresponding to the distance between the points. In other words, close points are close on the display, and distant points are far on the display. Note that each point may be arranged according to the required time between each point.

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

By displaying such a time schedule, not only the departure time and the arrival time to the destination, but also the scheduled time of each passing point and the section required time and the section distance including each passing point including the passing point are known. be able to.
In particular, since each point is displayed in the form of a bar associated with distance or time, the user can grasp the entire route as a sensation when viewed.

Then, it is determined whether the time has been changed (S1).
5). In this time change, any one of the scheduled times can be selected by operating the operation unit 14, and the scheduled time can be changed with the selected 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 and minute is displayed, and the scheduled time can be changed. In the illustrated example, the passage time at the passage point C has been changed from 8:20 to 9:10.

When the scheduled time is changed, the scheduled time of each point is recalculated (S1).
6). As a result, the transit time of 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 vehicle passes the passing point C at 9:10. And
Returning to S14, the time schedule is updated and displayed at the recalculated scheduled time. The input of the time may be a direct input of a numerical value or various methods such as clicking an arrow.

Then, if there is no change in the time in S15, this processing ends. As described above, according to the present embodiment, the scheduled passage time of each point can be changed. Accordingly, 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 respond to a request such as what time the user wants to arrive at the destination. Furthermore, it is possible to easily cope with a case where the schedule is changed after the travel plan is once set.

Further, in the screen shown in FIG. 3, by operating a predetermined button displayed on the screen, a route section / calculation table shown in FIG. 5 is displayed. In this table, the passing point on the route from the start point to the destination, the point name of the expressway interchange, the passing time, the required section time between each point, the section distance, and the section average speed are displayed. And in this example, as shown by an arrow next to the character display in the figure,
The passing time of each point, the required section time between each point, the section distance, and the section average speed can be changed. That is, on this screen, by specifying the changed item on the display and inputting a new numerical value here, the change can be made.

The change of the scheduled passage time is the same as in the case described above. When the section required time is changed, recalculation is performed, the scheduled passing time at the subsequent points is changed, and the corresponding section average speed changes.

On this screen, the average speed can be changed. As a result, the recalculation is performed, the required time of the corresponding section is changed, and the scheduled passage time at a subsequent point is changed.

In this way, the running mode of the predetermined section can be changed to the one desired by the user. Therefore, when a plurality of drivers drive, it is possible to set to run slowly in a predetermined section or to run relatively quickly according to the driver, and to make a travel plan to the destination based on the setting. .

The section required time may be changed on the screen shown in FIG. 3 (FIG. 4), and the average speed is also displayed on the screen shown in FIG. 3 (FIG. 4) so that it can be changed on the screen. Is also 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 time point and position in the route traveling at noon.
Instead of the 12 o'clock mark, another time mark may be adopted, and the user may be able to specify a time and create a specific time mark.

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

In addition, the scheduled arrival time and the scheduled departure time can be displayed for all points, and the break / break time can be displayed.
It is also preferable to calculate and display the estimated arrival time and the estimated departure time in consideration of the stop time. Also in this case, the break / stop time may be displayed. Further, it is also preferable to display both the arrival and departure times 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.

It is preferable that the adjustment and change of these schedules can be performed even after the start of traveling on the route. This allows you to take a break at an unscheduled point or receive a reschedule call,
It is possible to respond flexibly.

Further, when the vehicle cannot travel as scheduled and there is a delay in 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 indicate it to the user. is there.

In the above example, the map database 1
2, the required time of section, the estimated time of passage, etc. were calculated from the data stored in 2, but in consideration of 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 required section time, estimated time of passage, and the like.

[0036]

As described above, according to the present invention,
The scheduled travel time of points and the average traveling speed between points can be adjusted and the result after the adjustment can be viewed, so that the traveling plan can be easily adjusted and changed. In addition, it is easy to know where the user is at a specific time, which is convenient for planning.
