This navigation processing is basically the same as that executed by a general navigation device.

Next, the information display processing of the repair facility will be described.

FIG. 7 is a flowchart for explaining the information display processing of the repair facility executed by the information display device 1.

First, the user operation analyzer 50 determines whether or not a request for an information display process has been input to the input device 15 (step 1001). For example, in FIG.
When the button 15a provided on the front of the information display device 1 is pressed, the user operation analysis unit 50 determines that a request for information display processing has been input to the input device 15.

When a request for information display processing is input, the user operation analysis unit 50 instructs the menu drawing unit 58 to display a menu screen for allowing the user to select facility information on the display 11. put out. In response to this, the menu drawing section 58 generates a command for displaying the menu screen on the display 11. The graphic processing unit 59 displays a menu screen on the display 11 based on the command (step 1).
002).

FIG. 8A shows an example of the menu screen displayed on the display 11 in the process of step 1002. In the example illustrated in FIG. 8A, the user is caused to select an arbitrary item from items such as a repair facility, a hotel, a restaurant, and a parking lot.

Next, the user operation analysis unit 50 determines whether or not the item “repair facility” is selected from the menu screen displayed on the display 11 in step 1002 (step 1003).

When the item "repair facility" is selected, a menu screen for selecting whether or not the user's moving body 6 is in a state capable of self-propelling is displayed on the display 1.
A command is issued so as to be displayed in 1. In response, the menu drawing section 58 displays the menu screen on the display 1.
Generate a command to be displayed in No. 1. The graphic processing unit 59 displays a menu screen on the display 11 based on the command (step 100).

FIG. 8B shows an example of the menu screen displayed on the display 11 in the processing in step 1004. In the example shown in FIG. 8 (b), a question message “Can the vehicle run on its own?” Is displayed, and the user selects one of two items, “Yes” and “No”. I try to make it.

The items as shown in FIG. 8 are based on the facility information that can be provided by the information providing device 2 and the menu drawing unit 58
May be set in advance.

Next, the user operation analysis unit 50 analyzes the item selected from the menu screen displayed on the display 11 in step 1002. Then, the self-propelling permission / prohibition setting unit 70 sets the self-propelling permission / prohibition condition in accordance with the items analyzed by the user operation analysis unit 50. When the item analyzed by the user operation analysis unit 50 is “Yes”, a self-propelled condition is set. On the other hand, if the item is “No”, a self-propelled impossible condition is set (step 1005).

In step 1004, instead of displaying on the display 11 a menu screen for allowing the user to select whether or not the mobile unit 6 is in a self-propelled state, the menu displayed in step 1002 is displayed. The item "Self-propellable" is provided on the screen, and the item "Self-propellable"
After the item is selected, if the item "repair facility" is selected, the self-propelled condition is set.If the item "repair facility" is selected without the item "self-propellable" selected, ,
You may make it set a self-propelled | impossible disabling condition.

Next, the search range setting unit 60 determines the content of the information of the repair facility that the user intends to receive from the information providing device 2, that is, the search condition of the information of the repair facility in the information providing device 2 described later. Is set (step 1006).

The search range setting unit 60 obtains information on the current location calculated by the map match processing unit 56. In step 1005, the self-propelling permission / prohibition condition set by the self-propelling permission / prohibition setting unit 70 is acquired. Then, the obtained current location information and the self-propelled availability condition are set as search conditions for information on the repair facility.

Here, in addition to the current location information and the self-propelling condition, the search range setting unit 60 stores information on the failure, information on the manufacturer of the mobile unit 6, or information on a repair chain store or the like of which the user is a member. May also be set as a search condition.

By doing so, more detailed search can be performed in the information providing apparatus 2. In addition, since information provided from the information providing device 2 to the information display device 1 is carefully selected, it is also useful to reduce the amount of communication.

As for the contents of the failure, common failure names (for example, lack of gas, puncture, overheating, etc.)
Is preferably registered in the search range setting unit 60 in advance, and the registered fault name is displayed on the display 11 so that the user can select one of them. In addition, moving body 6
It is preferable that the manufacturer and the repair chain store of which the user is a member are registered in the search range setting unit 60 in advance.

Next, the search range setting section 60 issues a command to the display side communication device 21 to attach the identification information of the information display device 1 to the set search condition and transmit the information to the information providing device 2. . In response, the display-side communication device 21 transmits the search condition set by the search range setting unit 60 and the identification information of the information display device 1 to the information providing device 2 (step 1007). Here, the identification information of the information display device 1 is:
For example, when a telephone line such as a car phone or a mobile phone is used as the communication line 5, it corresponds to a user's telephone number or the like.

Next, the display-side communication device 21 waits for a response from the information providing device 2 (step 1008). When there is a response, the data transmitted from the information providing device 2 is transferred to the reception data analysis unit 61.

Next, the reception data analysis unit 61 analyzes the data transferred from the display-side communication device 21 (step 1009). Then, the information of the plurality of repair facilities included in the transferred data is selected, and the detailed information included in the information of the selected plurality of repair facilities, that is, the name of the repair facility, the position of the repair facility on the map. , Rescue service availability, rescue service operation status, service provision status,
Detect information such as contact information.

Next, the reception data analysis unit 61 determines the self-propelling availability condition set by the self-propelling availability setting unit 70 (step 1010). If the self-propelling availability condition indicates that self-propelling is possible, the process proceeds to step 1011;
Move to 6.

In step 1011, the icon drawing section 6
Reference numeral 4 denotes an icon for displaying information of each of the plurality of repair facilities analyzed by the reception data analysis unit 61, which is superimposed on the map displayed on the display 11. The display processing of this icon is performed in the following manner.

First, the icon drawing position setting section 63 sets the drawing position on the map drawn by the map drawing section 54 of the icon for displaying the information of each of the plurality of repair facilities analyzed by the received data analysis section 61. I do.

Next, the icon drawing section 64 reads, from the icon storage device 20, an icon for displaying each of the plurality of pieces of repair facility information analyzed by the received data analyzing section 61. Then, the read icon is drawn at the drawing position set by the icon drawing position setting unit 63.

FIG. 9 shows an example in which an icon for displaying information on the repair facility 3 is drawn on the map displayed on the display 11. By doing so, the user
The relationship between the current location of the moving body 6 and the position of the repair facility 3 can be easily grasped, and can be used as a reference when selecting the repair facility 3.

In the example shown in FIG. 9, one type of icon is used as an icon for displaying information on the repair facility, but, for example, the name of the repair facility included in the data analyzed by the received data analysis unit 61, For example, the drawing attributes such as the pattern, color, size, brightness, and blinking of the icon may be changed depending on whether the icon is a gas station or a dealer, and the icon may be displayed on the display 11. By doing so, the user can more accurately grasp the information on the repair facility only by looking at the icons.

Next, the individual information selection section 72 converts the facility information corresponding to the icon selected by the user from the icons displayed on the display 11 into the data analyzed by the reception data analysis section 61. (Step 1012). The selection process of the facility information is performed in the following manner.

First, the user operation analysis unit 50 waits for the user to select a part of the display screen of the display 11.

Here, the input device 15 for allowing the user to select a part of the display screen of the display 11 includes:
There are position input devices such as a touch panel that detects a position where pressure is applied to the display screen and a joystick that moves a cursor displayed on the display screen.

Next, when the user selects a part of the display screen, the user operation analysis unit 50 transmits information on the position of the display screen selected by the user to the individual information selection unit 72. In response to this, the individual information selection unit 72 sets the information of the repair facility corresponding to the icon displayed at the position,
The data is selected from the data analyzed by the reception data analysis unit 61.

By providing the joystick with a tab function and sequentially selecting icons in the same direction as the direction in which the joystick was pressed, information on the repair facility corresponding to the selected icon can be obtained. Alternatively, the data may be selected from the data analyzed by the reception data analysis unit 61.

Next, the individual information selecting section 72 executes Step 1
A command is issued to the icon drawing section 64 so that the content of the information on the repair facility corresponding to the icon selected in 012 is displayed on the display 11. In response to this, the icon drawing unit 64 causes the graphic processing unit 59 to execute step 10.
Information such as the name of the repair facility and the service providing state included in the information on the repair facility corresponding to the icon selected in 12 is displayed on the display 11 and an item for selecting whether or not to use the repair facility is displayed. It is displayed (step 1013).

FIG. 10 shows the display 1 of the repair facility information corresponding to the icon selected in step 1012.
1 shows a display example. When the user selects an arbitrary icon on the icon display screen shown in FIG. 10A, as shown in FIG. 10B, the name of the repair facility included in the information on the repair facility corresponding to the selected icon , Service provision status, repair cost, and other information are displayed. In addition, the item "decision" which means that the repair facility is used,
The item "return" which means not to use is displayed.
Thus, the user can easily determine whether to use the repair facility.

Next, the user operation analysis section 50 determines whether or not an item for using the repair facility displayed on the display 11 in step 1013 has been selected by the user (step 1014). If the item for using the repair facility is selected, step 1015
The process returns to step 1011 if not selected.

At Step 1015, Step 1012
The route guidance to the repair facility 3 corresponding to the icon selected by is performed.

First, the individual information selecting section 72 executes step 1
The information regarding the position of the repair facility 3 corresponding to the icon selected at 012 is transferred to the route calculation unit 51. In response to this, the route calculation unit 51 uses the map data stored in the map storage device 12 to calculate the current location of the mobile unit 6 calculated by the map match processing unit 56 and the repair sent from the individual information selection unit 72. A route connecting the location of the facility 3 is searched.

Next, the route guidance unit 52 includes the route calculation unit 51
Is compared with the current location obtained by the map match processing section 56, and the voice input / output device 14 determines whether the vehicle should go straight or turn left or right before passing through an intersection or the like. To inform the user by voice, or to draw the direction to proceed on the map displayed on the display 11 to inform the user.

By doing so, step 1012
The route guidance to the repair facility 3 corresponding to the icon selected by is performed.

For example, in FIG. 10B, when the item “determine” is selected, as shown in FIG. 10C, up to the repair facility 3 corresponding to the icon selected in FIG. Perform route guidance.

On the other hand, if it is determined in step 1010 that the self-propelled condition is not self-propelled and the process proceeds to step 1016, the inquiry destination drawing unit 71
A command for displaying the facility name, inquiry information, and the like included in the information of each of the plurality of repair facilities analyzed in the above on the display 11 in a listable format is generated. In response to this, the graphics processing unit 59 displays a predetermined image on the display 11 in accordance with the command generated by the inquiry destination drawing unit 59.

FIG. 1 shows a display 1 of the information display device 1.

4).

Steps 2001 to 200 described above
The processing of 4 is such that the information of the repair facility is periodically obtained from each of the repair facilities 3 connected to the network 4 or whenever the information display device 1 requests the provision of the information of the repair facility. The process is repeatedly executed so as to obtain information on the repair facility from the repair facility 3 near the current location of the moving body 6.

In this way, the information storage device 23
The information of the repair facility, which changes with time, that is, the operating status of the rescue service and the stock parts can be stored.

Next, an information providing process will be described.

FIG. 14 is a flowchart for explaining the information providing process performed by the information providing apparatus 2.

First, the user request analysis unit 82 waits for data to be sent from the information display device 1 via the provider communication device 28 (step 3001).

Next, the transmitted data is analyzed, and the identification information of the user and the information on the search condition included in the data are detected (step 3002).

Next, the information retrieval unit 83, in accordance with the retrieval conditions analyzed by the user request analysis unit 82,
The information of the repair facility stored in the storage facility is searched, and all the information of the repair facility that matches the search condition is detected (step 3).
003).

For example, if the search condition analyzed by the user request analysis unit 82 is the current location of the mobile unit 6 and the self-propelled condition “self-propelled”, the information of the repair facility within a predetermined range from the current location is retrieved. Search from the information storage device 23.

Further, for example, when the search condition analyzed by the user request analysis unit 82 is the current location of the mobile unit 6 and the self-propelled condition “non-self-propelled”, a repair facility located within a predetermined range from the current location. Then, the information storage device 23 is searched for information on the repair facility that provides the rescue service and the repair facility in which the rescue service is available.

Here, when search conditions are set in addition to the current location of the mobile unit 6 and the self-propelling availability condition, in addition to the information of the repair facility that matches all the search conditions, the current location of the mobile unit 6 and the self-propelled It is preferable to search the information storage device 23 for information on a repair facility that meets the availability condition. Then, the information of the searched repair facility is prioritized, and the information display device 1
Is preferably provided.

For example, if the search conditions analyzed by the user request analysis unit 82 are the current location of the mobile unit 6, the self-propelling availability condition “possible to run”, and the manufacturer of the mobile unit 6 “Company A”, From the information storage device 23, information on a repair facility that is within a predetermined range from the repair facility that handles the mobile unit made by the company A and a repair facility that is within a predetermined range from the current location are searched. Then, priorities are given so that information on repair facilities that meet all the search conditions is given priority, and the information is provided to the information display device 1.

In this case, on the information display device 1, the user selects a repair facility by displaying icons with different colors in the order of higher priority and displaying the icons in order of higher priority. You can refer to it above.

Various methods are conceivable as a method of searching for information with the failure content as one of the search conditions.

For example, a list of parts necessary for repairing the failure according to the content of the failure is registered in the information search unit 83 in advance. Then, the information corresponding to the failure analyzed by the user request analysis unit 82 can be performed by detecting the information of the repair facility 3 that has the stock parts from the information storage device 23.

Further, for example, information on a repair facility that meets other search conditions except for the failure content is stored in the information storage device 2.
3 to detect. Then, using the information acquisition device 27,
Repair facility 3 specified by detected repair facility information
To search for a repair facility capable of repairing the failure content by inquiring whether the failure content can be repaired.

[0177] At this time, in addition to the response from the repair facility 3 to which access has been made as to whether or not the content of the failure can be repaired, if the content of the failure can be repaired, the cost and time required for the repair are also answered. It is preferable to receive it.

By providing information on the repair cost and the repair time to the user of the mobile unit 6, the user can refer to the selection of the repair facility.

Next, the information processing section 84 includes an information retrieving section 83
The information of the repair facility 3 detected by the user request analysis unit 8
A request is made to the provider communication device 28 to transmit the information to the information display device 1 specified by the user identification information analyzed in step 2 (step 3004). In response to this, the provider communication device 28 communicates with the information display device 1.

In the navigation system according to the present embodiment, the information display device 1 transmits to the information providing device 2 search conditions including the current location of the mobile unit 6 and the self-propelling availability condition.

[0181] In response to this, the information providing apparatus 2 reads the information on the various repair facilities 3 that change with time from the information storage device 23 and stores the repair facilities 3 that match the search condition.
And transmits only the information of the matching repair facility 3 to the information display device 1.

When the self-propelling condition is “self-propelling”, the information display device 1 displays the information on the repair facility 3 sent from the information providing device 2 on the map as an icon, and the information is selected by the user. The route guidance to the repair facility 3 corresponding to the icon is performed.

On the other hand, when the self-propelling condition is “no self-propelling”,
A list of the inquiry information of the repair facility 3 sent from the information providing device 2 is displayed, and the inquiry destination selected by the user is contacted to arrange the rescue service.

As described above, according to the present embodiment, when a mobile unit breaks down, information on the repair facility is provided in a form corresponding to the mobile unit, taking into consideration whether the mobile unit can run on its own. Therefore, it is possible to provide appropriate repair facility information that meets the user's request.

[0185] In the case where the mobile object is not capable of self-propelled operation, the user can be provided with information on a repair facility that provides a rescue service and is in a state where the rescue service can be used. Therefore, information on the repair facility can be provided more efficiently.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention.

[0187] For example, in the above embodiment, the self-propelling permission / inhibition setting section 70 of the information display device 1 sets the self-propelling permission / inhibition condition in accordance with a user's instruction. Therefore,
It is important for the user to correctly recognize the failure of the moving object and determine whether or not the user can run by himself. Therefore, the information providing system of the present invention may be provided with a failure diagnosis function of the moving body 6 to help the user's recognition.

For example, a failure diagnosis device for detecting a trouble such as overheating which is difficult to self-run is attached to the engine of the moving body 6, and when a failure is detected by the device, the effect is notified by the voice input / output device 14 or the display. 11 may be used to call the user's attention. Also, in this case, the self-propelling permission / prohibition setting unit 70 may automatically request the information providing apparatus 2 to provide information on a repair facility that provides a rescue service by automatically setting the self-propelling disabling condition. Good.

Further, in the above embodiment, the information providing device 2 stores the information of various repair facilities in the information storage device 2.
3 has been described. However, the present invention is not limited to this.

For example, the information display device 1 is provided with a storage device in which information of various repair facilities is stored in advance, and the information display device 1 performs the information search of the repair facility which has been performed on the information providing device 2 side. You may.

In this case, it is impossible to cope with information that changes with time, such as the operation status of the rescue service and the status of stock parts. However, information that does not change throughout the year, such as the name and position of the repair facility, the contact information, and the presence or absence of a rescue service, can be sufficiently handled by storing the information in the storage device provided in the information display device 1. By doing so, it is possible to provide information on the repair facility even in a situation where access to the information providing apparatus 1 is difficult or the like.

In this case, various information of the repair facility 3 is separately stored in the storage device of the information display device 1 and the information storage device 23 of the information providing device 2. The apparatus 1 searches for information on the repair facility that matches the search condition, and accesses the information providing apparatus 2 only when the information on the matching repair facility cannot be detected. May be retrieved.

In this manner, the frequency of the number of times of communication between the information display device 1 and the information providing device 2 can be reduced.

In the above embodiment, the display side communication device 21 of the information display device 1 has a function of directly calling the repair facility 3, but the display side communication device 21 is at least an information providing device. Any device capable of exchanging data with the device 2 may be used.

If the display-side communication device 21 does not have a function of making a direct call to the repair facility, it is not possible to directly inquire the repair facility. In such a case,
When providing information on the repair facility, the information display device 1 may display the location of the nearest telephone facility on a map. Knowing the location of the telephone facility makes it easier for users to receive rescue services.

Further, in the above-described embodiment, the self-propelling permission / non-permission condition is set in the self-propelling permission / prohibition setting section 70 of the information display device 1.
