Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a navigation system in a moving body such as car navigation, and more particularly to a method and apparatus for reproducing generated travel route information.
[0002]
[Prior art]
Navigation devices typified by car navigation systems receive the radio waves from GPS (Global Positioning System) satellites orbiting the sky to determine the current position of people with mobile objects and devices such as cars, aircraft, and ships. It is a device that can display accurately in real time. Furthermore, recently, there is a car navigation system that has a function of calculating a travel route (movement route) to a destination only by setting the destination. According to the calculation of the travel route, the user can confirm the optimum route such as the shortest distance and the shortest time to the destination only by inputting the starting point and the destination, for example. This makes it possible to confirm the position after confirming the optimal route, not just the simple location confirmation using the GPS, and the calculation of the travel route is one of the functions that are very effective for the user.
[0003]
Conventionally, for example, there is a demand for confirming a traveling route by a personal computer (PC) in a home before traveling in a car. In this case, before the departure, a starting point and a destination are input by a home PC or the like, and a travel route is calculated. For example, the user confirms the route on a map.
[0004]
[Problems to be solved by the invention]
However, there is a problem that the travel route calculated by a home PC or the like cannot be reproduced by car navigation provided in the vehicle. In other words, even if the travel route from the same departure point to the same destination is calculated, the other systems have exactly the same travel route because the map data and calculation algorithm are different between the home PC and the car navigation system. It cannot be reproduced.
[0005]
In addition, in order to reproduce accurately, there is a method in which a driver (user) sets several relay points on the travel route calculated by the PC by car navigation and recalculates by the set car navigation. However, in this method, it takes a lot of time for the driver to set the vehicle to travel, which is very troublesome for the driver.
[0006]
The present invention has been made to solve such a technical problem, and an object of the present invention is to effectively reproduce the calculated movement route in other navigation systems.
Another object is to reproduce the calculated movement route in another navigation system without performing troublesome work by the user (user).
[0007]
[Means for Solving the Problems]
For this purpose, the present invention stores information on a movement path generated by a PC or the like in a portable memory such as a card-type semiconductor recording medium represented by Memory Stick (trademark). It is characterized by reading information about this movement route from this portable memory in a system such as navigation and reproducing the movement route, and reproducing the movement route without being aware of the difference in map data and calculation algorithm Making it possible. Therefore, the present invention is a movement path reproduction system that reproduces the movement path created by the first apparatus by the second apparatus, and the first apparatus includes an input means for inputting information on the destination. And a generating means for generating predetermined waypoint information based on the information on the destination, and a storing means for storing the generated waypoint information in a memory. The second device is stored in the memory. It is characterized by comprising a reading means for reading out the waypoint information and an output means for outputting the movement route information based on the read waypoint information.
[0008]
Here, the memory stored by the storage means is a portable memory such as a card-type semiconductor recording medium, and can store the route information by the first device, and can also store the route point by the second device. If the information is configured to be readable, the user can reproduce the movement route with a very simple operation. However, in some cases, it is also possible to configure the waypoint information to be distributed via wireless means or the like instead of the portable memory. Furthermore, if the input means is configured to input information related to the departure place in addition to the destination, the transit point information can be easily generated even if the information relating to the departure place is not provided.
[0009]
The route information generating apparatus to which the present invention is applied is used for interface information capable of storing data in the portable memory and for generating route information when a portable memory is connected.

[0010]
Here, the route information generated by the generating means may include a record of the name and / or road type of the road used from the departure point to the waypoint and from the waypoint to the destination. . In addition, when there are a plurality of waypoints, it is possible to further include a name and / or road type recorded from the waypoint to the waypoint. Furthermore, it is preferable to record the road width information, for example, in that a travel route can be accurately reproduced even when there are a plurality of roads with the same name (for example, an old road and a bypass).
It should be noted that the information regarding the departure place may be input from the input means, and for example, the position is recognized by a GPS receiver, or separately from position information stored in a RAM or the like. It is also possible to configure as described above.
[0011]
Further, the route information reproducing apparatus to which the present invention is applied includes an interface unit that can connect a portable memory such as a card-type semiconductor recording medium in which destination information and route information are stored, and a memory in the interface unit. A reading means for reading destination information and route information from the memory when connected, a movement route calculating means for calculating a movement route based on the destination information and route information read by the reading means; An output means for outputting the movement route calculated by the movement route calculation means on a map is provided.
[0012]
Here, the route information stored in the portable memory is information generated by a device having a calculation algorithm different from that of the route information reproduction device, and the movement route calculation means is a device having a different calculation algorithm. The movement route is calculated based on the route information generated by the above. In the present invention, the data stored in the portable memory is not map data or calculation data, but is only destination information and route information, and is configured to be calculated again by a reproduced route information reproduction device. Thus, data can be transferred using a portable memory with a small storage capacity. Further, as the interface means, a portable memory can be configured to be detachable, and can be connected by inserting this memory.
[0013]
The present invention is also a movement route reproduction method for reproducing a movement route created by a first device by a second device having a calculation algorithm of the movement route different from that of the first device. Based on the information about the starting point and the destination input by the device, the first device generates information about the predetermined waypoint, and based on the information about the starting point and the destination and the information about the generated waypoint Then, the movement path can be reproduced in the second device.
Here, a portable memory is interposed between the first device and the second device, and information relating to the waypoints generated by the first device, information about the departure point, and the destination are generated in the memory. It can also be configured to store and read this information by the second device. It is also possible to configure such information to be transmitted / received via a net or the like without a portable memory.
[0014]
On the other hand, according to the present invention, in a storage medium in which a computer program that can be executed by a computer that can be connected to a portable memory is stored so as to be readable by the computer, the program recognizes input starting point information and destination information. Processing, detection of a predetermined waypoint based on the recognized departure point information and destination point information, processing for generating route information between the departure point and the route point, and between the route point and the destination point, and detection It is possible to cause the computer to execute a process of storing the received waypoints and the generated route information in a portable memory using a predetermined description format.

[0017]
When writing data from the PC 10 to the card type semiconductor storage medium 30, the CPU 11 reads data to be written from the HDD 17 as necessary and transmits it to the card type semiconductor storage medium 30 via the IF unit 12. Conversely, when reading data from the card-type semiconductor storage medium 30 to the PC 10, the CPU 11 issues a data read request to the card-type semiconductor storage medium 30 via the IF unit 12 of the PC 10. The card type semiconductor storage medium 30 transmits data in the storage unit 31 to the PC 10 side via the IF unit 32 in response to a request. The CPU 11 that has received the data via the IF unit 12 displays the data on the CRT 18 so as to be visible to the user (user) via the CRT display unit 13 as necessary.
[0018]
FIG. 3 shows a display example of a map and a travel route displayed on the CRT 18 on the PC 10. In FIG. 3, map data in a part of Tokyo is displayed, and a starting point 61, a destination 62, and a calculated route 63 are shown.
In order to display a map, the CPU 11 extracts map data of a region necessary for display from map data stored in the CD-ROM 14 or the HDD 17 of the PC 10, converts the map data into a map image, and passes through the CRT display unit 13. Displayed on the CRT 18. The starting point 61 and the destination 62 are configured so that a user (user) can input using the mouse 20 and the keyboard 19 and input to the CPU 11 via the operation unit 15. In order to calculate the travel route, the CPU 11 calculates the route calculation data around the departure point 61 and the destination 62 and the route around the departure point 61 and the destination 62 from the map data stored in the CD-ROM 14 and the HDD 17.

In the present embodiment, the route 63 can be displayed by a broken line as shown in FIG.
[0019]
FIG. 4 is a block diagram for explaining the configuration of the car navigation system 40 according to the present embodiment. The vehicle navigation 40 is configured to store the CPU 41 and the card type semiconductor storage medium 30 that control the whole, and is connected (interfaced) to the IF unit 32 of the card type semiconductor storage medium 30 to read data. It has. In addition, a RAM 43 for storing various data, an LCD 46 for displaying a map, an LCD display unit 45 for controlling the LCD 46, a CD-ROM 44 for storing map information, and a nonvolatile memory for storing an operation program for the car navigation system 40 49, a GPS receiver 47 and a gyro 48. The vehicle navigation 40 uses the GPS receiver 47 and a gyro 48 that understands the behavior of the vehicle, such as deceleration, acceleration, and right / left turn, to accurately measure the position of the vehicle. The map data centered on the assumed position of the own vehicle is read from the CD-ROM 44, and the CPU 41 creates a map display frame and displays it on the LCD 46 via the LCD display unit 45. Further, the CPU 41 can read position information in the storage unit 31 of the card type semiconductor storage medium 30 via the IF unit 42. The read data can be stored in the RAM 43 of the car navigation system 40.
[0020]
Conventionally, there is a request to confirm a travel route by using a PC 10 or the like in the home before traveling by car. As described above, the departure point 61 and the destination 62 are input by the PC 10 or the like, and the travel route is calculated. As shown in FIG. 3, an operation for confirming the route 63 on the map has been performed. The travel route on the PC 10 often reproduces the exact same travel route even if the departure point 61 and the destination 62 are similarly input by car navigation in the car because of different map data and calculation algorithms. I couldn't. In order to reproduce it accurately, it was necessary to set several relay points on the travel route in the car navigation and recalculate with the car navigation, and it was necessary to perform a very troublesome work. In this embodiment, in order to eliminate this troublesomeness, the travel route calculated by the PC 10 can be recorded on the card-type semiconductor storage medium 30 and can be easily transmitted to the car navigation system 40 which is a car navigation system.
[0021]
However, if the road link information of all travel routes is recorded on the card-type semiconductor storage medium 30, the amount of data becomes enormous, and the data recorded by the PC 10 due to differences in the map data recording format and route guidance methods. Cannot be used in the car navigation system 40 as it is. Therefore, in the present embodiment, as will be described below, the travel route can be reproduced even if the recording format of the map data and the route guidance method are different between the PC 10 and the car navigation system 40. It is configured.
[0022]
FIG. 5 is a diagram for explaining the contents of the travel route information. As shown in FIG. 5, the route 63 can be represented by travel route information such as an intersection name and a road name. Intersections other than the starting point 61 and the destination 62 can be handled as transit points on the travel route. The road used in the route 63 can be handled as route information from the departure point 61 to the transit point, from the transit point to the transit point, and from the transit point to the destination 62. In the present embodiment, four route points from waypoints 1 to 4 between the departure point 61 and the destination 62 are represented by the intersection route and the road route information of the road name, respectively.
[0023]
FIG. 6 is a diagram detailing the information from the starting point 61, the destination 62, and the waypoints 1 to 4 shown in FIG. In the present embodiment, the point name, latitude, and longitude of the departure point 61, the destination 62, and the waypoints 1 to 4, the route point 1 from the departure point 61, the route point 2 to 3, and the route point 3 to 4, The road name and road type of each used road from the waypoint 4 to the destination 62 are recorded. In addition, in order to recalculate the route 63 from the departure point 61 to the transit point 1, from the transit point 2-3 to the transit point 3-4, and from the transit point 4 to the destination 62, as a route calculation condition, Road width and priority conditions are recorded.
[0024]
FIG. 7 is a diagram showing a description actually recorded on the card-type semiconductor storage medium 30. In this embodiment, XML (Extensible Markup Language) is used as an example. Here, in one file, the information of the departure point 61, a plurality of waypoints 1 to 4 and the destination 62, the route point 1 from the departure point 61, the route points 1 to 3, the route points 2 to 4, and the route point 4 are included. Each road information from the destination to the destination 62 is described, and the order is arranged from the departure point 61 to the destination 62 in the order of travel.
[0025]
FIG. 8 is a diagram illustrating an example of storing a travel route information file. In the present embodiment, in consideration of the convenience of the user, the driving route information file is stored in the card-type semiconductor storage medium 30 with a predetermined file name in a predetermined directory. By simply inserting the card-type semiconductor storage medium 30 into the in-vehicle navigation system 40, the travel route calculated by the PC 10 can be automatically reproduced without setting work. An example of the structure of this directory is shown in FIG. The root directory 71 is managed in a hierarchical structure with a HIFI directory 72 used for audio, a VOICE directory 73 used for recording, and a position (POSION) directory 74 used for navigation. The travel route information file calculated by the PC 10 of the present embodiment is stored in the position directory 74 under the route directory 71 under the file name AutoRt.poi (AutoRt.poi file 75). When the in-vehicle navigation system 40 finds the AutoRt.poi file 75 in the position directory 74, it automatically reproduces the travel route, displays the route on the map, and then starts route guidance for the driver (user). It is configured.
[0026]
Next, the flow of processing in the present embodiment will be described with reference to FIGS. FIG. 9 shows a flow for calculating a travel route on the PC 10 and a flowchart for creating data for recording the calculated travel route information on the card-type semiconductor storage medium 30. First, the departure point is received from the keyboard 19 and mouse 20 in the PC 10 (step 101). Similarly, the destination point is received from the keyboard 19 and the mouse 20 (step 102). The CPU 11 in the PC 10 sets search conditions (step 103) and performs route calculation (step 104). Next, the departure place information is written in the file of the card type semiconductor storage medium 30 (step 105). It is possible to write the data to the RAM 16 of the PC 10 once and write it to the card type semiconductor storage medium 30 when all the data is ready.
[0027]
Further, the CPU 11 determines whether or not there is a route change point to the destination 62 (step 106). If there is a route change point, the route information up to the route change point is written in the file of the card type semiconductor storage medium 30 (step 107). Then, the route change point information is written to the file as route point information (step 108). Thereafter, the process returns to the determination in step 106 to further determine whether or not there is a route change point. On the other hand, if there is no route change point in step 106, the route information to the destination 62 is written in the file of the card type semiconductor storage medium 30 (step 109), and the destination information is written in the file (step 110). The series of processes for recording the path information of the PC 10 in the file of the card type semiconductor storage medium 30 is completed. As described above, in this embodiment, a point whose road name or road type is changed on the calculated travel route is picked up as a route change point, and each time a route change point is found, the route information and the waypoint It is possible to write the point information such as in the file of the card type semiconductor storage medium 30.
[0028]
FIG. 10 is a flowchart of route reproduction in the vehicle-mounted navigation 40. The travel route information calculated by the PC 10 by the processing shown in FIG. 9 is read into the in-vehicle navigation 40 via the card type semiconductor storage medium 30, and the travel route is reproduced by recalculating in the in-vehicle navigation 40. First, after the card-type semiconductor storage medium 30 is inserted, the CPU 41 of the vehicle-mounted navigation 40 determines whether or not there is a travel route information file (AutoRt.poi file 75) in the card-type semiconductor storage medium 30 (step 111). ). If it does not exist, the process ends. If it exists, the information of the departure point 61 is extracted from the travel route information file and set as Route Origin (search start point) (step 112). Next, route information is extracted from the travel route information file and set in Route Condition (search condition) (step 113). Then, route point information or destination 62 is extracted from the travel route information file and set as Route Destination (search end point) (step 114). Further, the route search is executed with the Route Condition from Route Origin to Route Destination (step 115). It is determined whether or not the reading from the travel route information file has been completed (step 116). If completed, all the searched routes are combined and displayed as one route on the LCD 46 (step 117). The process ends. On the other hand, if not completed in step 116, the value of Route Destination is set to Route Origin (step 118), and the setting from step 113 is repeated. As described above, in the vehicle-mounted navigation 40 according to the present embodiment, the departure point 61, the waypoint, and the destination 62 are sequentially extracted from the travel route information file (AutoRt.poi file 75) existing in the card type semiconductor storage medium 30. The route calculation conditions between the departure point 61 and the waypoint, between the waypoint and the waypoint, and between the waypoint and the destination 62 are also read out. Then, it is possible to perform a route calculation between each of the read route calculation conditions as a search condition, and to reproduce a travel route that is exactly the same as the travel route calculated by the PC 10.
[0029]
FIG. 11 is a flowchart for explaining the flow of the automatic route reproduction process in the present embodiment. First, it is determined whether or not the card-type semiconductor storage medium 30 has been inserted into the vehicle-mounted navigation 40 (step 121). If not, the process ends. If it is inserted, it is determined whether or not the AutoRt.poi file 75 exists in the position directory 74 of the card-type semiconductor storage medium 30 (step 122). If it does not exist, the process ends. If it exists, the travel route is reproduced by the CPU 41 of the in-vehicle navigation 40 (step 123), and the reproduced travel route is displayed on the map of the LCD 46 (step 124). Then, positioning by the GPS receiver 47 and route guidance by the gyro 48 are started for the driver (user) (step 125).
[0030]
As described above, there has been a request for confirming a travel route by using the PC 10 in the home before traveling by car. However, the map data and the calculation algorithm of the PC 10 and the vehicle-mounted navigation 40 are completely different. The same route could not be reproduced and each other could not be used effectively. However, according to the present embodiment, the travel route calculated by the PC 10 can be easily transmitted to the in-vehicle navigation system 40 via the card-type semiconductor storage medium 30. Further, since the travel route calculated by the PC 10 is automatically reproduced simply by inserting the card-type semiconductor storage medium 30 into the vehicle-mounted navigation 40, the driver (user) is troublesome to input all the relay points, for example. Work can be omitted, and an excellent navigation system that is easy to use for the driver (user) can be provided.
[0031]
In the above-described embodiment, the example in which the card type semiconductor storage medium 30 is used has been described. However, the present embodiment is not limited to this, and the semiconductor storage medium other than the card type, the magnetic recording type medium, and the like are used. Can be selected arbitrarily. In some cases, the travel route information can be transmitted via a wireless or wired network or the like without using media. However, according to the card type semiconductor storage medium 30, it is not necessary to provide a large drive device for reading and writing, and the medium is excellent in portability, and is very suitable for executing this embodiment.
[0032]
Further, although XML has been described as an example of a description format for recording a travel route, the present invention is not limited to this description format, and it is also possible to adopt a recording method such as HTML other than XML. Further, the map data of the PC 10 and the vehicle-mounted navigation 40 is read from the CD-ROMs 14 and 44, but is not limited to this, and is not limited to this, but an optical recording medium such as DVD or MO, tape, hard disk, etc. It is also possible to use map data in magnetic recording media and semiconductor recording media. Moreover, although the travel route has been described based on a road, it is not necessarily limited to this, and a route such as a ferry, a railroad, or a European Eurotunnel may be used. In such a case, for example, the name of a port or the name of a station will be a relay point (route). Furthermore, although the travel route information file is the AutoRt.poi file 75 in the position directory 74, it may be a different file name in a directory with a different name.
[0033]
Furthermore, in the present embodiment, the method for reproducing the route calculated by the PC 10 with the in-vehicle navigation 40 has been described. However, the present invention is not limited to this example, and the route may be reproduced with a portable information terminal or a notebook PC other than the in-vehicle navigation 40 Is possible. Conversely, the travel route calculated by the in-vehicle navigation 40 may be reproduced by the PC 10, or may be configured to be reproduced by another car navigation, a portable information terminal, a notebook PC, or the like. Is possible.
In this embodiment, the starting point and the destination are input by the user. However, the starting point (current position) can be recognized by, for example, the GPS receiving unit 47 or installed in advance by the PC 10. If the registered location can be registered, there is no need to input it every time the route is searched.
[0034]
In addition to the case where the program for executing each function of the present embodiment is stored in advance in each device (PC 10, in-vehicle navigation 40), for example, a storage medium such as a CD-ROM in which these execution programs are stored It is also possible to configure to read the program from A mode in which the program is installed in the PC 10 or the like by distribution using the Internet or the like is also conceivable. In particular, in the PC 10, the functions in the present embodiment are often added as an application program thereafter.
[0035]
【The invention's effect】
As described above in detail, according to the present invention, for example, a travel route calculated by a device such as a PC can be effectively used in a device such as another navigation system without a troublesome operation by a user (user). Can be reproduced.
