Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device for providing route guidance to a destination based on a destination or other point input.

[0002]

2. Description of the Related Art There has been proposed a navigation device that provides time guidance such as scheduled arrival time at a destination, as a navigation device that provides route guidance to a destination (for example, Japanese Patent Application Laid-Open No. HEI 5-5-2). 53507, JP-A-9-243382). These include, for example, selecting a destination based on the estimated arrival time at the destination stored in advance, displaying the destination information on a map screen, and displaying time information such as a schedule time and an estimated arrival time at the destination. It is displayed in association with distance information to the destination.

However, in a conventional navigation device,
By setting the destination based on the point input, the expected arrival time is calculated from the calculated travel distance of the route to the destination, and the element of the desired date and time for the input point such as the destination is determined. Not what you type. That is,
Regarding the concept of time on the system side, the estimated time of arrival is obtained and displayed using the current location and the route to the destination input by the user, the distance calculated therefrom, the current time, and the traveling speed. Therefore, in the conventional navigation device, when there are a plurality of destinations and there is a temporal order, a route is set by inputting points in the passing (arrival) order, or the set route is rearranged. It becomes necessary. In addition, when driving the vehicle, it is necessary to input a point such as a desired destination,
It is not possible to enter the destination in advance along with the date and time in advance. Moreover, although the estimated time of arrival is displayed, there is no information relating to the desired time of arrival, so it is necessary to calculate and judge the degree of time margin based on the expected time of arrival and the desired time of arrival. Become.

Further, when a plurality of passing points are input, a route search is performed by designating a passing order, or a route search is performed by optimizing a passing order without specifying a passing order. Enter the final destination and schedule time (time to go to the stopover or destination),
A system has been proposed in which a route search is performed by automatically specifying a transit order according to a schedule time (for example, JP-A-2-3899, JP-A-8-210868). However, in these cases, the passing order of the passing points is designated in advance, such as by specifying the passing order itself or the time, and the route is searched and guided in the passing order, and the passing order is optimized by the system. This is a search, and does not take into account the concept of time or the running state as the running state of the user, and does not appropriately respond to the usage state of each user. In addition, since the conventional device displays a two-dimensional (planar) expression as a screen for inputting a schedule time such as a route point and a final destination, it is possible to input “close” or “close” when inputting the time. It is difficult to grasp the positional relationship with the current time on a continuous time axis such as "slightly ahead".

[0005]

In the navigation device according to the present invention, as shown in FIG. 2, first, as a schedule input, together with points such as a destination, a transit point, and a passing point, a point for which time is specified is time information and a point for which no time is specified. Enter the rank information. (Step S11).
Here, the rank information indicates, for example, the priority and the weight of the request, and when there is no room for time and it is necessary to change or delete a point, the rank is changed from a point with a lower rank (priority) as a target. Or delete. next,
The route is set according to the schedule of the point designated by time (step S12). Then, the current position is tracked along the set route (step S13), and guidance is executed until the vehicle reaches the destination (step S14).

In the processing up to the arrival at the destination, a passing point having the following time constraint (time designation) is extracted (step S).
15), calculate the time margin a (step S1)
6). It is determined whether the calculated temporal margin a is equal to or smaller than the minimum margin reference value a1 (step S17) or equal to or greater than the marginal reference value a2 (step S18). If the calculated temporal margin a is within the range of the reference values a1 and a2 (NO in steps S17 and S18), the process returns to step S13 to continue the current position tracking. When the margin a is too large (Step S18)
If the answer is YES), a pass point addition process is performed (step S19), and the process returns to step S13 to continue the current position tracking.

The calculated time margin a is equal to the reference value a.
If the time is less than 1 (YE in step S17)
In the case of S), a pass point up to the next pass point with a time constraint, that is, a pass point with no designated time is extracted (step S20), and a pass point of the lowest rank is selected (step S20).
21). FIG. 3C shows an example of a display screen based on the result. Therefore, the user instructs whether to delete or change here, and determines either one (step S22).

When the instruction is changed, an alternative point of the selected passing point is selected (step S23), and it is determined whether or not the instruction of the user is OK (step S24). The route is reset with the point as the passing point (step S25), and the process returns to step S3.
If the instruction is to be deleted in step S22, the passing point is deleted (step S26), the route is reset (step S27), and the process returns to step S13 to continue the current position tracking.

Next, the present invention will be described based on an example of a display screen and specific processing in the above processing. FIG. 3 is a diagram showing an example of a schedule input screen and a guide screen, FIG. 4 is a diagram showing an example of a screen when a passing point is changed, and FIGS. 5 and 6 are examples of a screen when a passing point is added. Figure showing
FIG. 7 is a diagram for explaining an example of a process of selecting a substitute value of a passing point, and FIG. 8 is a diagram for explaining an example of a passing point adding process. In FIGS. 3, 5, and 6, the bar-shaped screen displayed on one side on the lower side of the screen is a schedule bar, which is used to specify a time along with route information such as a current position mark, a passing point, and a destination. It indicates the degree of the time margin at the point where it is performed.

First, in the schedule input in step S11, for example, as shown in FIG.
Along with points A to F such as passing points, time information is given to points A and B where meetings, meals and other times are specified, and ranks are given to points C to F where the time is not particularly specified but time is not required. Enter information 1-3. Here, the rank information is, for example, a target of a passing point to be changed or deleted when the time margin from the point of rank 3 is lost. In other words, when it is not possible to arrive at the point A or B at the designated time, that is, when there is no time margin, first □
□ It means that the bookstore and then the xx cleaning shop will be changed or deleted to another bookstore or laundry shop. FIGS. 3B and 3C show examples of the display screen during the current position tracking based on the time margin, showing the current position mark, the map around the current position, the route, and the lower part of FIG. Lateral route is B (△△ restaurant) from current position
This indicates that the settings are made in the order of E → C → A → D → F. Double circles displayed between points on the set route indicate
The estimated time of arrival at the point designated by the time is sufficiently longer than the designated time, that is, the time margin a is large, and the double △ indicates that the time margin a is gone. Is shown.

For example, the present time and the current position, the position and the time of the input points A and B are detected, and the estimated arrival time to the specified points A and B is determined based on the set route and the traveling speed between them. When the time margin a for arriving at the point A to the designated time is exhausted, as shown in FIG. 3C, the user is asked whether to delete or change the bookstore C having the lowest rank as a candidate as shown in FIG. . When the user instructs a change, a bookstore C 'of the same genre is selected as a substitute for C as shown in FIG.
Ask whether or not. If the user gives an OK to this alternative point, a re-search is performed to display all the routes as shown in FIG. 4B, and then the screen returns to the current position tracking screen shown in FIG. 4C.

If there is sufficient time to arrive at the designated time at the point A, as shown in FIG. 5 (A), there is sufficient time as the passing point addition processing, and For example, it is possible to drop in at a coffee shop, and as shown in FIG. 5B, a coffee shop G existing along the route is searched and displayed, and a request (OK?) Is heard.
When the user instructs OK, a new coffee shop G is added as a passing point as shown in FIG. 5C, and the route is reset. In order to perform such a process, as a recommended genre to stop by when the system has enough time in advance,
For example, a coffee shop or a pachinko parlor is registered. Alternatively, after displaying a message indicating that there is enough time, the user may input a genre or point to visit, and reset the route.

FIG. 6A shows an example of a screen for setting conditions when entering a schedule in preparation for adding a passing point.
When entering a schedule, if you have time to spare and add a passing point, you may want to stop by, for example, bookstore by genre specification,
** It may be selected in advance like a general store. By making such a setting, as shown in FIG. 6 (B), it is suggested that the user drop in if there is enough time when passing through a desired point, for example, within a predetermined distance from the cake shop. Then, if the user indicates OK, as shown in FIG. 6 (C), the user stops and searches for a route passing through the desired point to guide the user.

The calculation of the time margin and the display thereof are performed, for example, as follows. Current position X ₀ ,
The current time T ₀ , the position X ₁ of the point A with the designated time, and the time T ₁ are detected, and according to the set route, X ₀ and X ₁
Obtains a distance L ₁ between. Further, the preset traveling speed is, for example, uniformly 25 km / h for a general road, and 80 km / h for an expressway, or as an average speed for each section based on traffic information obtained by a data transmitting / receiving device. Ask. Based on the traveling speed, a predicted required time t of the distance L ₁ is obtained, and a ratio (T ₁ −T ₀ ) / t from the time of the current position to the specified time at the point A is defined as a time margin. a. In this case, if a> 1, there is a temporal margin, and if a <1, there is no temporal margin. Further, a difference (T ₁ −T ₀ −) between the remaining time (T ₁ −T ₀ ) from the current position to the point A and the predicted predetermined time t.
t), and the ratio (T ₁ −T ₀ −t) / L ₁ of this value and the distance L ₁ between the current position and the point A may be used as the time margin a. In this case, a> 0, and the larger the value of a, the greater the time margin, and if a <0, it is determined that there is no temporal margin. Therefore, double ○, double △, and double x indicating the time margin can be defined by these numerical ranges.

Next, an example of a specific process for selecting an alternative point will be described. In the process of selecting an alternative point, for example, as shown in FIG. 7, first, the selected passing point is deleted, and a route between the current position and the next passing point or destination after the deleted passing point is searched. (Step S31). Then, the genre of the deleted passing point is determined (step S32), and a facility along the route between the current position and the next passing point or the destination is searched in that genre (step S33). It is determined whether or not it is (step S34). If the facility cannot be searched, the genre of the passing point that was deleted further,
A facility within a predetermined distance from the current position and the route between the next passing point or the destination is searched (step S35), and it is determined whether or not the facility has been searched (step S36). If the facility can be searched in step S34 or S36, the facility closest to the deleted passing point is selected from the searched facilities and selected as an alternative point (step S3).
7).

A specific example of the passing point adding process will be described.
In the passing point adding process, for example, as shown in FIG. 8, first, a search is made for a drop-in desired point registered within a predetermined distance from the current position (step S41). As a result, it is determined whether there is a desired point (step S42), and if not, whether there is a desired genre (step S4).
Determine 3). If there is no genre to stop by, as shown in FIG. 5, a genre other than the designated pass point is searched for a facility of the recommended genre closest to the current position among recommended genres (step S44), and as shown in FIG. If there is a desired genre, the facility of the desired genre closest to the current position is searched (step S4).
5). It is determined whether or not there is a facility by these searches (step S46).
If there is a desired point, the searched point is set as a passing point and a re-search is performed (step S47), and a passing point with the next time constraint is extracted (step S48). Then, the time margin a 'is calculated (step S49),
It is determined whether or not a '≧ a3 (step S50). With this, it is determined whether or not there is still enough time to stop at some unexpected place and spend time. And
If a '≧ a3, there is sufficient time, so a message for confirming the addition of a point is displayed (step S5).
1). When determining a ′ ≧ a3, a time margin may be observed according to a preset condition, for example, based on 30 minutes in the case of a coffee shop, and how much time is available as a margin time is displayed. You may. Then, it is determined whether or not the user's instruction for displaying the message for confirming the addition of the point is OK (step S52).
The route searched in 47 is set as a guidance route (step S53). In the navigation device according to the present invention, based on the input of the point with time designation and the point without time designation as described above, a point with time designation is set. At the same time, the route to the destination is set via a point with no designated time, so for a point with designated time, it is calculated based on the designated time, the distance of the set route, and the traveling speed according to the road type. And the expected arrival time of each point. Therefore, it is possible to determine a time margin from these times, and it is possible to delete, change, and add points, and to set a time space along a route and manage a schedule.

Next, a scheduler for managing a schedule in a time space will be described. FIG. 9 is a diagram showing a display of the time space of the scheduler and an operation example thereof, FIG. 10 is a diagram showing an input example of the schedule, FIG. 11 is a diagram showing a display example of the schedule, and FIG. FIG. 13 is a diagram for explaining an example of a display process of a scheduler screen, and FIG. 14 is a diagram for explaining an example of a display process of an information box.

For example, as shown in FIG. 9, the center of the scheduler screen is set to infinity time, the outermost frame is set to the current time,
Alternatively, a time box screen consisting of a rectangular frame obtained by dividing the time every 30 minutes is displayed in the middle of the specified time, and the current time or the specified time is displayed at the lower left of the screen, and the time is set upward. Display the scheduled bar. Then, the selected time is highlighted as a selected time frame on the time box screen, and △ is displayed on the schedule bar. FIG. 9A shows a display example of the current time of 16:00 and the selected state. In the time scroll mode of the scheduler screen, when a scroll operation is performed with a joystick, a jog dial, or the like, the time frame moves outward in the time box screen with an image of proceeding through the time tunnel, and the outermost frame (that is, △ is displayed at the time of the schedule bar corresponding to the first time frame). FIG. 9B shows an example of the display, where the display position of △ indicates the scroll time, and the shaded △ indicates the current time. FIG. 9C shows a display example in which the screen is fixed, the schedule input mode is set, and the time is designated by the cursor at 9:15. As described above, in the present invention, the time is scrolled and selected using the scheduler screen, and the schedule is input at the selected time, or the schedule input for each time is displayed and confirmed.
By linking the set route with the time and selecting the time, it is possible to display information near the route that will travel at that time, to perform confirmation or search.
Further, specific examples thereof will be described.

Now, when inputting a schedule from 9:15 to 10:00, a start time frame and an end time frame are selected as shown in FIG.
As shown in the figure, a schedule box is displayed in a time frame of 9:15, that is, a time section, and a schedule is input.

When a schedule is input, and each point is input to set a route to the destination, FIG.
As shown in the schedule bar, the expected passage time of the route,
Each point is displayed according to the estimated time of arrival. At this time, a point whose time is specified is fixed to the time of the schedule bar. Therefore, if the estimated time of arrival is too early at a point designated by the time, the time margin is increased and a passing point can be added, and if the estimated time of arrival is later,
Since it is necessary to delete or change the waypoints, we will make those proposals. Incidentally, passing predicted time, estimated arrival time point X ₁ on the route can be determined, for example, as follows. First, a distance L ₁ from the current position X ₀ is obtained,
Further, the traveling speed set in advance is, for example, 25 km / h for a regular road and 80 km for an expressway.
/ H as obtaining the value obtained by dividing the distance L ₁ at a speed as predicted traveling time. Then, the calculated expected time is added to the current time to obtain an expected time. Further, the estimated travel time may be obtained in consideration of the traffic information obtained by the data transmitting / receiving device.

When confirming the previous schedule, when approaching point A by scrolling, the schedule is displayed on the section at the scheduled time 13:00 as shown in FIG. 11B, and when the enter key is further pressed, the schedule is displayed. As shown in FIG. 11C, “map”, “place name”,
The information key of "information" and "search around" is displayed. When "map" is selected, a map centered on the point and a position mark are superimposed and displayed thereon, and when "place name" is selected, the place name is displayed and "information" is selected. And the road information such as the road name and the traffic information are displayed. When "surrounding search" is selected, the facility of the selected genre is searched for and displayed within a predetermined range from that point.

For example, FIG. 12A shows an example in which a map of a parking lot is displayed when "parking lot" is selected as a genre after "surrounding search" is selected. FIG. 12B shows a display example using two screens, ie, a route display and a time box screen, as a pseudo route scroll using the cursor keys. In FIG. 12B, the left screen is the route scroll screen, and the right screen is the time box screen. The predicted time at that point is highlighted on the time box screen in accordance with the traveling position of the route scroll screen. In the time box screen on the right side, a thick frame indicates a pseudo vehicle position.
In the route scroll, when there is information set on the time box screen, or when there is position information on the route or traveling information on the route, for example, FIG.
As shown in (C), these information items are displayed, and further, information keys for searching for surroundings and detailed information are displayed. For example, regarding the traveling position on the route scroll screen shown in FIG. 12 (C), in the time box screen, the expected time of traveling near {city} town is 13:25 minutes, and the next passing point A starts from here.
It is calculated that it is 15.5 km and takes about 31 minutes, and it is displayed. The peripheral search key can be used to search for information on the surrounding area, and the detailed information key displays the detailed information of the point.

In the display of the scheduler screen, the current time is acquired as shown in FIG. 13 (step S61), and FIG.
As shown in (A), the current time is set to the nearest side (outside), and a time section is determined and displayed from the near side to the far side (step S62). Next, it is determined whether or not time scrolling is performed (step S63). In the case of time scrolling, as shown in FIG. 9C, the highlighted time frame is moved as a time cursor (step S64) and stopped. Is reached (step S65), the time at the cursor position is determined (step S66). Thereafter, step S63 is performed again.
