BACKGROUND OF THE INVENTION
The present invention relates to a navigation apparatus that performs route guidance to a destination by inputting a destination and other points.
[0002]
[Prior art and problems to be solved by the invention]
As a navigation device that performs route guidance to a destination, devices that manage time such as scheduled arrival time at the destination have been proposed (for example, Japanese Patent Laid-Open Nos. 5-53507 and 9-243382). These include, for example, selecting a destination based on a pre-stored arrival time at a destination and displaying the destination information on a map screen, or 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.
[0003]
However, in the conventional navigation device, by setting the destination based on the point input, the estimated arrival time is obtained from the calculated travel distance of the route to the destination. However, it does not input the desired date and time element. In other words, the time concept on the system side is only to obtain and display the estimated arrival time using the current location, the route to the destination input by the user, the distance calculated from the current location, the current time, and the traveling speed. Absent. Therefore, in the conventional navigation device, when there are a plurality of destinations and there is a time order, the route is set by inputting the points in the passing (arrival) order, or the set routes are rearranged. It will be necessary. In addition, when driving the vehicle, it is necessary to input a point such as a desired destination, and it is not possible to input the destination in advance along with the date and time. In addition, although the expected arrival time is displayed, there is no information related to the desired arrival time, so the degree of time margin needs to be calculated and judged based on the expected arrival time and the desired arrival time. Become.
[0004]
Furthermore, when entering multiple passing points, a route search is performed by specifying a passing order, or a route search is performed by optimizing the passing order without specifying a passing order, and a route point and a final destination are designated as a schedule. And a schedule time (time to go to a waypoint or destination) are input, and a route search is proposed by automatically specifying a route order according to the schedule time (for example, Japanese Patent Laid-Open No. 2-3899). (Kaihei 8-210868). However, these are specified in advance by specifying the passing order of the passing points, such as specifying the passing order itself or by the time, searching for the route in the passing order and guiding the route, and by optimizing the passing order by the system. It is to be searched, and does not take into account the time concept or the running state as the running state of the user, and does not appropriately correspond to the use state of each individual user.
[0005]
Therefore, the present invention To the destination you entered In a navigation device that provides route guidance, By specifying the time for the destination and other points Schedule input means for inputting a schedule for traveling schedule, route setting means for setting a route to the destination based on the schedule input, current position detecting means for detecting the current position, and current time detecting means for detecting the current time When, According to the set route, the time margin from the detected current position and the current time to the schedule input point From the margin calculation means to calculate and the current position To destination and other points A display control means for displaying information indicating the time margin together with the route information on a display means is provided.
[0006]
Further, the display control means is based on the inputted schedule. Display of the display means The schedule bar is displayed on one side of the screen. In the schedule bar One end of the current position and current time The specified time for the destination entered in the schedule Display the time margin according to the margin In the schedule bar Change the shape of the mark and display the time margin according to the margin. In the schedule bar This is characterized in that the mark color and density are changed for display.
[0007]
The display control means displays a schedule bar on one side of the screen, and the schedule bar displays an input time at a point where the time is specified, with one end being a current position and a current time, The time margin is displayed by changing the shape of the mark, the color and density of the mark in accordance with the margin.
[0008]

[0017]
Next, the operation will be described. FIG. 2 is a diagram for explaining the overall flow of the navigation apparatus according to the present invention. .
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 stopover point, and a passing point, the point where time is specified, the time information where the time is not specified Enter rank information. (Step S11). Here, the rank information indicates, for example, the priority and the weight of the request, and when there is no time margin and it is necessary to change or delete a point, the rank information is changed as a target from a point with a lower rank (priority). Or for deleting. Next, a route is set according to the schedule of the point designated for time (step S12). Then, the current position is traced along the set route (step S13), and guidance is executed until the destination is reached (step S14).
[0018]
In the process until arrival at the destination, a passing point having the next time restriction (time designation) is extracted (step S15), and a time margin a is calculated (step S16). It is determined whether the calculated temporal allowance a is equal to or less than the reference value a1 of the minimum allowance (step S17) or greater than the reference value a2 where there is too much allowance (step S18). When the calculated time margin a is within the range between the reference values a1 and a2 (when both are NO in steps S17 and S18), the process returns to step S13 and the current position tracking is continued. If the margin a is too large (YES in step S18), a passing point addition process is performed (step S19), the process returns to step S13, and the current position tracking is continued.
[0019]
If the calculated time margin a is equal to or less than the reference value a1 and there is no time margin (YES in step S17), the passing point up to the next passing point with time constraints, that is, the time designation A passing point having no rank is extracted (step S20), and a passing point having the lowest rank is selected (step S21). An example of the display screen based on the result is shown in FIG. Therefore, since the user instructs here whether to delete or change, either one is determined (step S22).
[0020]
If the instruction is changed, an alternative point of the selected passing point is selected (step S23), and it is determined whether or not the user's instruction is OK (step S24). The route is reset as a point (step S25), and the process returns to step S3. If not OK, or if the instruction is deleted in step S22, the passing point is deleted (step S26), and the route is reset. Setting is performed (step S27), the process returns to step S13, and the current position tracking is continued.
[0021]
Next, the present invention will be described based on the display screen and specific processing examples in the above processing. 3 is a diagram showing an example of a schedule input screen and a guidance screen, FIG. 4 is a diagram showing an example of a screen when changing a passing point, and FIGS. 5 and 6 are examples of screens when adding a passing point. FIG. 7 is a diagram for explaining an example of a selection process of a substitute value for a passing point, and FIG. 8 is a diagram for explaining an example of a passing point addition process. 3, 5, and 6, the bar-like screen displayed on one side on the lower side of the screen is a schedule bar, and includes time information such as a current position mark, passing point, and destination information. This represents the degree of time margin at the designated point.
[0022]
First, in the schedule input in step S11, for example, as shown in FIG. 3 (A), the points A and B such as destinations, waypoints, and passing points, as well as points A and B where time designation is performed for meetings, meals, and the like Rank information 1 to 3 is input to the points C to F where the time information and the time are not particularly specified but the time designation is not desired. Here, the rank information is, for example, a passing point that is changed or deleted when the time margin from the point of rank 3 is lost. In other words, if you cannot arrive at point A or B at the specified time, that is, if there is no time margin, first change □□ bookstore, then XX cleaning store to another bookstore or cleaning store, or delete It is to become a target. 3 (B) and 3 (C) show examples of display screens during the current position tracking based on the time margin, showing the mark of the current position, the surrounding map, and the route, In the horizontal direction, the route is set from E → C → A → D → F from the current position to B (ΔΔ restaurant). The double circles displayed between the points of the set route indicate that the estimated arrival time at the time designated point is sufficiently larger than the designated time, that is, the time margin a is large, The double triangle Δ indicates that the time margin “a” has disappeared.
[0023]
For example, the current time and current position, the position and time of the input points A and B are detected, and the estimated arrival time to the points A and B with time designation based on the set route and the travel speed between them is obtained. When there is no time margin a to arrive at the designated time in A, as shown in FIG. 3C, the user is asked whether to delete or change the lowest-ranked bookstore C as a candidate. When the user instructs change, the bookstore C ′ of the same genre is selected as an alternative point for C as shown in FIG. If the user indicates OK to this alternative point, a re-search is performed and all routes are displayed as shown in FIG. 4B, and then the current position tracking screen shown in FIG.
[0024]
Further, when there is a sufficient time margin for arriving at the point A until the specified time, as a passing point addition process, there is a time margin as shown in FIG. The user can search for and display a coffee shop G that exists along the route as shown in FIG. 5B, and asks for hope (OK?). When the user instructs OK, a coffee shop G is newly added as a passing point as shown in FIG. In order to perform such processing, for example, a coffee shop or a pachinko parlor is registered in advance as a recommended genre to drop in when there is time on the system side. In addition, after displaying a message indicating that there is enough time, a genre or a point that the user wants to drop in may be input to reset the route.
[0025]
Fig. 6 (A) shows an example of the screen when conditions are set when inputting a schedule in preparation for adding a passing point. For example, a bookstore by genre designation, a □□ cake shop that specifies a point, or a ** general store may be selected in advance. By making such a setting, as shown in FIG. 6 (B), it is proposed to stop if there is a time allowance when passing within a predetermined distance from the desired location, for example, □□ If the user points to OK, the route is searched and guided as shown in FIG.
[0026]
The calculation and display of the time margin as described above are performed, for example, as follows. Current position X 0 , Current time T 0 , Position X of point A with time designation 1 , Time T 1 And follow the set route, X 0 And X 1 Distance L between 1 Ask for. Furthermore, the preset travel speed is, for example, a uniform 25 km / h for general roads and a uniform 80 km / h for expressways, or an average speed for each section based on traffic information obtained by the data transmitter / receiver. Ask. Based on this travel speed, the distance L 1 Is calculated from the current position time to the specified time at the point A (T 1 -T 0 ) / T is a time margin a. In this case, if a> 1, there is a time margin, and if a <1, there is no time margin. The remaining time from the current position to point A (T 1 -T 0 ) And the predicted time t (T 1 -T 0 -T), and the distance L between this value and the current position and the point A 1 Ratio (T 1 -T 0 -T) / L 1 May be the time margin a. In this case, a> 0 and the larger the value of a, the larger the time margin, and if a <0, there is no time margin. Therefore, it is possible to define double circles, double triangles, and double circles indicating time margins by these numerical ranges.
[0027]
Next, an example of specific processing 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 of 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 with the genre (step S33). It is determined whether or not (step S34). If the facility cannot be searched, the facility can be searched by searching for a facility within a predetermined distance from the route between the current position and the next passing point or the destination in the genre of the deleted passing point (step S35). It is determined whether or not (step S36). If the facility can be searched in step S34 or S36, the facility closest to the passing point deleted from the searched facilities is selected and selected as an alternative point (step S37).
[0028]
A specific example of the passing point addition process will be described. In the passing point addition process, for example, as shown in FIG. 8, first, a desired stop point is searched for within a predetermined distance from the current position (step S41). As a result, it is determined whether or not there is a desired point (step S42), and if not, it is determined whether or not there is a desired genre to stop by (step S43). If there is no desired genre to drop in, as shown in FIG. 5, a recommended genre facility closest to the current position is searched for among genres other than the designated passing point (step S44), as shown in FIG. If there is a desired genre, the facility of the desired genre closest to the current position is searched (step S45). It is determined whether or not there is a facility by these searches (step S46). If there is a facility, and if there is a desired point in step S42, the searched point is set as a passing point and re-search is performed ( Step S47), the next passing point with time restriction is extracted (Step S48). Then, a time margin a ′ is calculated (step S49), and it is determined whether a ′ ≧ a3 (step S50). Now, if you stop by somewhere unscheduled and spend time, you can determine if you still have time. When a ′ ≧ a3, there is sufficient time, so a message for confirming the addition of a point is displayed (step S51). When determining a ′ ≧ a3, for example, in the case of a coffee shop, 30 minutes may be used as a reference, and a time allowance may be observed in accordance with preset conditions, and how much time is available is displayed. May be. Then, it is determined whether or not the user's instruction for the display of the point addition confirmation message is OK (step S52). If OK, the route searched in step S47 is set as the 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, the route to the destination via the point without time designation is matched with the point with time designation. Therefore, for a point with a designated time, the designated time, the distance of the set route, and the estimated arrival time of each point obtained based on the traveling speed according to the road type are included. Therefore, it is possible to determine a time margin from these times, and it is possible to delete, change, and add points, and it is possible to set a time space along the route and manage the schedule.
[0029]
Next, a scheduler for managing a schedule in time space will be described. 9 is a diagram showing a time space display of the scheduler and an operation example thereof, FIG. 10 is a diagram showing an example of schedule input, FIG. 11 is a diagram showing a display example of the schedule, and FIG. 12 is a link example of the scheduler and set route information. FIG. 13 is a diagram for explaining an example of scheduler screen display processing, and FIG. 14 is a diagram for explaining an example of information box display processing.
[0030]
For example, as shown in FIG. 9, the scheduler screen is a time box screen composed of rectangular frames in which the center of the screen is set to infinity and the outermost frame is set to the current time or the specified time, and the time is divided every 30 minutes. Is displayed, the current time or the specified time is displayed at the bottom of the left side of the screen, and a schedule bar in which the time is set upward is displayed. The selected time is highlighted as a selected time frame on the time box screen, and Δ is displayed on the schedule bar. FIG. 9A shows a display example of the selection state when the current time is 16:00. In the time scroll mode of the scheduler screen, when the scroll operation is performed with a joystick, jog dial, etc., the time box moves to the outside with the image of going forward through the time tunnel on the time box screen. Δ is displayed at the time on the schedule bar corresponding to the time frame before the first). FIG. 9B shows the display example, where the display position of Δ indicates the scroll time, and the shaded Δ 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 9:15 with the cursor. As described above, in the present invention, the scheduler screen is used to scroll and select the time, the schedule is input at the selected time, the input schedule is displayed for each time, and the setting is performed. By linking the route and time and selecting the time, it is possible to display information on the vicinity of the route that will travel at that time and perform confirmation or search. Furthermore, specific examples thereof will be described.
[0031]
When inputting a schedule from 9:15 to 10:00, select a time frame for each of the start time and end time as shown in FIG. 10 (A), and 9:15 as shown in FIG. 10 (B). Display the schedule box in the time frame, that is, the time section, and enter the schedule.
[0032]
When a schedule is input and each point is input and a route to the destination is set, each point is displayed on the schedule bar according to the expected passage time and the estimated arrival time as shown in FIG. . At this time, a point with a specified time is fixed at the time of the schedule bar. Therefore, if the estimated arrival time is too early at a point where time is specified, the time margin will be increased and a passing point can be added, and if the estimated arrival time is later, the passing point will be deleted or changed. Will need to make those suggestions. In addition, point X on the route 1 The estimated passage time and the estimated arrival time can be obtained as follows, for example. First, the current position X 0 Distance L from 1 Further, the distance L is set at a preset traveling speed of, for example, 25 km / h uniformly for general roads and 80 km / h for highways. 1 Is obtained by dividing the vehicle speed by the traveling speed as the estimated traveling time. Then, the estimated traveling time is obtained by adding the obtained estimated traveling time to the current time. Moreover, you may obtain | require driving | running | working estimated time in consideration of the traffic information obtained by the data transmitter / receiver.
[0033]
When confirming the previous schedule, when the user approaches point A by scrolling, the schedule is displayed on the cross section at the scheduled time 13:00 as shown in FIG. 11B, and when the enter is further pressed, FIG. As shown in (C), information keys of “map”, “place name”, “information”, and “periphery search” in the information box in the time section are displayed. When “Map” is selected, a map centered on that point and a position mark are superimposed on it, and when “Place name” is selected, the place name is displayed and “Information” is selected. And road information such as a road name and traffic information is displayed. When “search around” is selected, facilities of a genre selected within a predetermined range from that point are searched and displayed.
[0034]
For example, FIG. 12A shows an example in which a map of the parking lot is displayed by selecting “parking lot” as a genre after “periphery search” is selected. FIG. 12B shows a display example using two screens including a route display and a time box screen as a route scroll that is simulated by a cursor key. In FIG. 12B, the left screen is a route scroll screen and the right side is a time box screen, and the predicted time at that point is highlighted on the time box screen corresponding to the travel position on the route scroll screen. In the time box screen on the right side, a thick frame indicates a pseudo vehicle position. In this route scroll, when there is information set on the time box screen, or when there is location information on the route or traveling information on the route, for example, such information is displayed as shown in FIG. Further, a peripheral search and detailed information key are displayed. For example, with respect to the travel position on the route scroll screen shown in FIG. 12C, on the time box screen, the estimated travel time in the vicinity of the city △ Δ is 13:25 minutes. It is calculated that 5 km is required and about 31 minutes are calculated and displayed, the surrounding information can be searched by the surrounding search key, and the detailed information of the point is displayed by the detailed information key.
[0035]
The scheduler screen displays the current time as shown in FIG. 13 (step S61), and the current time is the front (outside) as shown in FIG. Is determined and displayed (step S62). Next, it is determined whether or not time scrolling is performed (step S63). In the case of time scrolling, the highlighted time frame is moved as a time cursor as shown in FIG. 9C (step S64) and stopped. If it becomes (step S65), the time at the cursor position is determined (step S66).

In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible. For example, in the above embodiment, schedule input is performed based on the table, but specific input methods include voice input and key input, time input and existing point indication on the bar, time You may make it input time on a box screen. Furthermore, in the time box screen, the time frame is represented by a rectangle as shown in FIG. 9, but for example, a scale is displayed on the time axis, or a time reference point is represented at the center of the time box screen. However, it goes without saying that, for example, a method such as setting the time box screen above may be used, or the time box screen may be changed to a distance box screen. For example, FIG. 15 is a diagram showing a display example using a distance box screen. In addition to the time box screen, a plurality of distance frames that are sequentially enlarged from the center as a distance box screen as shown in FIG. Each position of the displayed route that is displayed may be associated with the distance frame based on the travel distance. In addition, the time margin is a comparison between the estimated time of arrival at the next point obtained based on the route set from the current position and current time and the specified time, and a comparison between the required time to the next point and the remaining time. Comparison based on speed, that is, the speed obtained from the remaining distance and time from the current position to the next point, and the average traveling speed obtained from the standard traveling speed of each section of the route, and calculated based on the ratio May be. In addition to ○, ×, △, etc., the time allowance may be displayed by color, density, blinking of those indications, etc., or even if the display is changed steplessly according to the allowance You may be made to notify by voice.
[0038]
In addition, the facility business days and hours, priority information by genre, and information acquired from VICS are stored in the memory as unique information, and it is determined whether or not it can be included in the route as an input point when inputting a schedule. Then, when it is outside the business day or business hours, the point may be displayed or an alternative may be proposed. Also, it is proposed to detect the remaining amount of gasoline in the vehicle, and if there is a gas station in the schedule, determine whether it is possible to reach the planned gas station and go through the gas station first. May be. Furthermore, we obtain weather information and traffic congestion information for each destination from the destination route and estimated transit time, suggest changes to the schedule according to the time margin, and correct the expected time due to a decrease in travel speed. May be proposed.
