Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a device for route search, a method and a device for route guidance, and an automobile equipped with a navigation device.

[0002]

2. Description of the Related Art Navigation devices mounted on vehicles using GPS (Global Satellite Positioning System) and GPS
GPS receivers, which are portable navigation devices that use GPS, are becoming popular. The most basic function of these navigation devices is to measure their current position and display the current position on a screen.

[0003] However, currently available navigation devices generally include, as an additional function, a route to a destination via a transit point based on a user setting the destination and the transit point. A search is performed on the road based on the conditions such as distance, required time, and road width, and the searched route (recommended route) is displayed on the screen, and guidance for matching the course with the recommended route according to the current position is provided by voice or image. There is a route search and guidance function to go by.

[0004] On the other hand, based on a user setting a destination and a waypoint, a route to the destination via the waypoint is determined based on a required time and a fare from a route of a public transportation such as a railway. There is a route search system for public transportation that searches and displays the searched route on a screen.

[0005]

By the way, when a user wants to set a departure time or an arrival time to a specific time when traveling by public transportation to a destination, the user not only reduces the required time and the fare. There is. Conventionally, in such a case, the user has been inconvenienced to check a diagram of a public transportation system using a timetable or the like.

[0006] On the other hand, when the user decides the destination,
It is not always decided in advance whether the means of transportation to the destination should be other than public transportation or public transportation,
If both public transportation and non-public transportation are candidates for transportation (for example, if you want to decide on the shorter travel time between automobile and railway, or combine automobile and railway, If the time is shorter, you may want to do so).

[0007] When it is desired to move a specific section by means of transportation other than public transportation and to move the remaining section by public transportation (for example, by moving to a station in front of the destination by rail and then from there to the destination) To get to the nearest station by car, and then travel by train to the destination).

In addition, when traveling by car to the destination but there is a ferry route along the way (for example, when traveling by car from Honshu to Hokkaido, it is necessary to board the ferry, There is also the option of boarding a ferry or crossing a bridge, such as when traveling by car to Shikoku).

However, the route search and guidance function of the conventional navigation device can search for a route only from a road (ie, a route not using public transportation).
In addition, in the conventional route search system for public transportation,
You can only search for routes from within public transportation routes.

[0010] Therefore, when both the means other than the public transportation and the public transportation are candidates for the means of transportation, the user uses both the navigation device and the route search system for the public transportation to search for the means. Compare and examine the results. If you have only a navigation device, check the route of public transport with a timetable, etc. If you have only a route search system for public transport, check the road with a road atlas etc. Or the inconvenience of having to do it.

[0011] Also, when a specific section is moved by means of transportation other than public transportation, and the remaining section is moved by public transportation, the user must perform navigation for a section moved by means of transportation other than public transportation. Use the route search system for public transportation for sections using public transportation while using the device, or check the timetable etc. for sections traveling on public transportation if you only have a navigation device, If there is only a route search system for public transportation, there is an inconvenience that sections traveling by means of transportation other than public transportation must be checked with a road atlas or the like.

[0012] In addition, in the case of traveling by car to a destination but a ferry route exists along the way, the user must
For roads, use navigation equipment and use the route search system for public transportation for ferry routes.If you have only navigation equipment, check the ferry routes with timetables, etc.
If there is only a route search system for public transportation, the inconvenience of having to search for roads using a road atlas or the like has been forced.

Accordingly, an object of the present invention is to enable a user to search for a route to a destination without inconveniencing the user even in each of the above cases.

The hardware configuration of such a navigation device may be the same as the existing one. However, the flash ROM 4 contains a program code for processing as will be described next with reference to FIGS. 3 to 12, and the user can also input a command in this processing to a specific operation key on the remote controller 26. Is assigned as a key to be operated when performing the operation. FIG. 2 is merely an example, and it goes without saying that the present invention may be applied to a navigation device having a hardware configuration different from that of FIG.

FIG. 3 is a block diagram showing an example of a route search / display system realized in the navigation device shown in FIGS. 1 and 2, in which double-lined blocks are respectively realized by specific hardware. The single line block is realized by the processing of the main CPU 1. The remote controller 26 and the remote controller light receiving section 12 are the same as those shown in FIGS. The state management unit 41 manages the state of the entire system based on a command input by the user using the remote controller 26.

Upon receiving a trigger from the state management unit 41, the map display control unit 42 sends an instruction to move the map, change the scale, change the color scheme, and the like to the map drawing control unit 43. The map drawing control unit 43 determines a necessary data area based on an instruction from the map display control unit 42, and acquires data of the area from the map information management unit 44. The acquired data is transferred to the display memory 4 via the display controller 47.
8 is drawn.

The map information management unit 44 includes a map drawing control unit 4
3 is stored in the CD-ROM shown in FIG.
Read from ROM 10. Further, the map data 49 determined as unnecessary by the map drawing control unit 43 is discarded. The route information 45 is information indicating the route searched by the route search unit 46. The route search unit 46 includes map data 49,
Based on the public transportation data 50 and the current position measured by the GPS controller 11 and the gyro sensor 13 in FIG. 2, a route matching the search condition set by the user is searched.

The display controller 47 controls the display of an image on the display section 52 (color palette control, display area control, etc.), and is assigned the peripheral control device 6 of FIG. The display memory 48 includes the DR shown in FIG.
An area in AM2 is allocated. Display memory 4
The data in 8 is read out by the display controller 47 and converted into a display signal, and the display signal is sent to the display unit 52, so that an image of a map or a route is displayed on the display unit 52. The map data 49 corresponds to the CD-ROM 1 shown in FIG.
0 is stored.

The public transportation data 50 is digital data of diagrams, routes, and fares of a plurality of types of public transportation (for example, railways, buses, and ferries). The public transportation data 50 is the CD-ROM 1 of FIG.
0 or stored in the flash ROM 4. However, public transportation diagrams and fares are often revised, so the Internet unit 2 in FIGS.
7, the latest public transportation data 50 may be obtained by accessing the Internet. The time management unit 51 manages the current time. The display unit 52 has L in FIG. 1 and FIG.
CD 22 is assigned.

Next, FIGS. 4 to 7 show the route search unit 4 shown in FIG.
6 shows an example of a storage format of the public transportation data 50 and a combination of the public transportation data 50 and the map data 49 in FIG. For example, as shown in FIG. 4, the route search unit 46 converts the route data including a plurality of places where the user can get on and off (in the figure, the data of a railway line including a plurality of stations) in the public transportation data 50 into each station v1, With v2,... v9 as points, the points of adjacent stations are represented by a graph connected by sides. As the length of this side, at least one of the required time, distance, and fare of the train between the adjacent stations is determined as the cost (weight). In the case where there are a plurality of flights at different places where people can get on and off in the same type of public transportation, for example, an express train and a train stop at each station, the graph is expressed for each flight.

Then, as shown in FIG. 5, for each side on this graph, the coordinate data of the stations at both ends of the side and the cost data are stored. (In the figure, only the required time is drawn as the cost, but it goes without saying that the required time, distance and fare may all be used as the cost.)

The route search unit 46 expresses the data of the road in the map data 49 on the same graph as the data of the route of the public transportation. That is, as shown in FIG. 6, for example, the data of the roads around the stations v1 and v2 are connected to the intersections n3, n4,... It is represented by a graph connecting edges and intersections adjacent to it. The length of this side is determined in proportion to the distance between adjacent intersections (or stations).

Then, as shown in FIG. 7, for each side on the graph, coordinate data and distance data of intersections (or stations) at both ends of the side are stored. At this time, data in which the distance is converted into the required time by car is also stored according to the road attribute (for example, 40 km / h for a general road and 80 km / h for an expressway).

The route search unit 46, based on the diagram data in the public transportation data 50, for example, as shown in FIG.
As shown in (1), data of departure time and arrival time between adjacent stations is also stored.

The data format of the public transportation data 50 shown in FIG. 3 is such that data can be stored in the format shown in FIGS. 5 and 8, or the map data 49 can be stored in the format shown in FIG. Any form may be used as long as it can be combined (in other words, a place where the user can get on and off the public transportation route corresponds to a point on the road).

Next, FIG. 9 is a flowchart showing an example of a process in which a route is searched and displayed by the route search and display system of FIG. First, the user sets a search condition using the remote controller 26 (step S1).
The search conditions include destinations, transit points, types of public transportation (trains, buses, ferries, etc., and in the case of railways, distinctions between express trains, express trains, and stops at stations, etc.) For each section to the transit point and for the section from the final transit point to the destination, the type of public transportation desired to be used preferentially, whether or not a diagram of the public transportation is added, and the like are included.
The method of setting a destination or a waypoint is similar to that of an existing navigation device, in which a cursor displayed on a map on the LCD 22 is moved to a desired position and the position is determined as the destination or waypoint. Alternatively, a location searched based on a keyword (for example, a word of a bank or department store) input by a user may be determined as a destination or a waypoint.

Subsequently, based on the search conditions, an area for acquiring information necessary for searching for a route is determined (step S).
2). This area is assumed to have a certain margin around the rectangular area including all of the starting point (for example, the current position), the transit point, and the destination. Although not shown in FIG. 9, when a route that meets the search conditions cannot be searched from the area determined in step S2, the search may be performed with the margin further increased. .

Subsequently, for the determined area, information on roads necessary for route search (step S3), information on railways (step S4), and information on public transportation other than railways (step S5) are obtained. Then, using the acquired information, the graph is created and the data is saved as shown in FIGS. 4 to 8 (step S6). At this time, saving of the data in the format as shown in FIG. 8 is performed only when the setting in consideration of the diagram of the public transportation is made in step S1. Then, information on the current time is obtained (step S7).

Subsequently, a route search is performed by the Dijkstra method (step S8). In this search, as shown in FIG. 10, the starting point (departure point) is set as a set (step S1).
1), the next point to be added to this set is determined (step S12). In the determination of the point to be added, when setting is made so as not to take into account the diagram of public transportation in step S1, as shown in FIG. 11, a point connected to this set is obtained (step S21). This is performed by selecting a point having the shortest arrival time from the start point (step S22).

On the other hand, if the setting is made in consideration of the diagram of the public transportation in step S1, a point to be connected to this set is determined (step S31) as shown in FIG. The calculation is performed by calculating the arrival times at the points and selecting the point having the earliest arrival time (step S32). The arrival time at the determined point is held until the search is completed (step S33). In the process of FIG. 12, the departure time is set as the arrival time for the start point.

Subsequently, the determined point is added to this set (step S13). Then, the same process is repeated until the end point (destination) is included in this set (steps S14, S12, S13), and the search ends. When the end point is included in this set, the route from the departure point to the destination is an optimal route for the set search condition.

Returning to FIG. 9, when the route search is completed, a display signal containing the search result is generated (step S).
9) Display an image based on the display signal (step S)
10). Then, the process ends.

As is clear from the above description, in this vehicle, the type of public transportation to be used can be set, and from both the route and the road of the set type of public transportation, The route to the destination via the waypoint is searched. This allows you to use both automobiles and public transportation as potential transportation options, or if you want to use only certain types of public transportation but don't want to use other types of transportation, Even when traveling by car to a destination and a ferry route exists along the way, an optimal route to the destination is searched for without inconvenience to the user.

Further, since the diagram of the public transportation system is taken into account, even when the user wants to travel by public transportation at a specific time, an optimum route is searched without inconvenience to the user.

Also, by setting the type of public transportation for each section to each transit point and for the section from the final transit point to the destination, a specific section is moved by car and the remaining sections are Even if you want to travel by transportation, the optimal route is searched without inconvenience to the user.

In the above example, the present invention is applied to a vehicle equipped with a navigation device. However, the navigation device itself (either a navigation device mounted on a car or a GPS receiver which is a portable type navigation device may be used.
In the case of a receiver, it may be for land use or for water use. In a GPS receiver for water use, a route that does not use public transportation is a water route instead of a road. It is clear from the above description that the present invention can be applied to a route search system other than the navigation system for searching for a route to a destination. Further, the present invention is not limited to the above-described example, and it is needless to say that various other configurations can be adopted without departing from the gist of the present invention.
