The functions of these means are achieved by the computer of the information center 40 executing the programs described below.

Next, the operation of the information providing system thus constructed will be described. (First location ID associating method) FIG.
No. 0 computer (hereinafter simply referred to as "information center 40") is a destination (place) included in the schedule information.
Based on the location-related information (for example, the address of the destination, the facility name of the destination, the telephone number of the facility, etc.), the position (location information) represented by the latitude and longitude of the destination is specified, and A position ID is attached to the specified position, and a program executed to manage the schedule information and the position in association with each other by the position ID is shown. This program is executed every time a predetermined time elapses or when a new schedule is input from the vehicle-mounted terminal 20 to the information center 40 by communication.

More specifically, the information center 40 starts the processing of this program from step 200 at a predetermined timing, proceeds to step 202, and stores the schedule stored in the schedule information database 42 for each individual. The schedule information (schedule data) of a specific individual is acquired from the information.

As shown in FIG. 3, the schedule information includes a schedule ID (schedule identification number) unique to each schedule, a notification status indicating whether or not the schedule has been notified to the person, a start date and time of the schedule, and an end. Date and time, destination name, schedule content, type indicating the origin of the schedule, such as whether the schedule is set by the user or automatically set, destination address, destination telephone number (fixed The telephone number), the name of the facility of the moving destination, the position ID that identifies the position of the moving destination, and the ID of the person who participates in the schedule (participant ID). Of these, the address of the destination, the telephone number of the destination, the facility name of the destination, and the location ID constitute position-related information, and the participant ID constitutes participant information.

The data within the range indicated by the arrow A in FIG. 3 among the schedule information is the data input to the vehicle-mounted terminal 20 by the user via the input means 24. Further, the inputted schedule information is transmitted to the information center 40 via the schedule information transmitting / receiving means 25 and the network 10, and is supplied to the schedule information database 42 via the schedule managing means 41 of the information center 40 to be stored therein. To be done.

The information center 40 then proceeds to step 204.
Then, in step 204, it is determined whether or not the acquired schedule information includes telephone number information (actual telephone number corresponding to the telephone number item). Therefore, the position ID does not exist at this stage.

Continuing the explanation assuming that the acquired schedule information includes telephone number information, the information center 40 makes a “Yes” determination at step 204 to proceed to step 206, at which step At 206, a data search using the telephone number as a keyword in the map information database 54 is performed by the point search means 52 (point search program).
By. In other words, a set of data including a telephone number that matches the telephone number (hereinafter, referred to as a data set) is searched from the data in the map information database 54.
The data set includes a phone number, name, latitude and longitude. The information center 40 then proceeds to step 208.
Then, in step 208, it is determined whether or not the number of data sets (search results) found by the search is more than one.

In this case, if there is only one search result,
The information center 40 makes a “No” determination at step 208 to proceed to step 210, and at step 210 determines whether or not there is only one search result. In this case, since there is only one search result, the information center 40 determines “Yes” even in step 210 and proceeds to step 212 to allow the user to confirm that this search result is correct. And an instruction signal for displaying the comment of (1) on the display means 22 is transmitted to the vehicle-mounted terminal 20.

At this time, when the user performs an input operation indicating that the search result is correct, using the input means 24, the signal input by the operation is transmitted to the information center 40. When the information center 40 receives this signal, the process proceeds to step 214, and in step 214, the position ID is added to the data set as the search result, and the same position I
The schedule information is associated with the location information consisting of the data set by D.

That is, as shown in FIG. 3, the information center 40 adds the assigned position ID to the schedule information (that is, writes the assigned position ID in the position ID column) and stores it in the schedule information database 42. At the same time, the position information database 45 stores the position ID, the schedule ID included in the schedule information, and the position information including the name, latitude, and longitude included in the data set as one set. After that, information center 4
If 0, the process proceeds to step 295 to end this program once.

On the other hand, if there are two or more search results during the execution of step 208, the information center 40 makes a “Yes” determination at step 208 to determine at step 216.
Then, in step 216, the user is caused to select appropriate information from a plurality of search results. Specifically, the information center 40 transmits to the vehicle-mounted terminal 20 an instruction signal that causes the display unit 22 to display a search result and a comment for allowing the user to select an appropriate search result from the search results.

As a result, when the user specifies one of the search results by the input means 24, the specified search result is transmitted from the vehicle-mounted terminal 20 to the information center 40,
The information center 40 proceeds to step 212 described above to retransmit the specified search result to the vehicle-mounted terminal 20 and to display a comment on the display means 22 for the user to confirm that the search result is correct. Is transmitted to the vehicle-mounted terminal 20.

After that, when the information center 40 receives the confirmation signal from the vehicle-mounted terminal 20 by the user, the information center 40 proceeds to the above-mentioned step 214 to give the position ID, and associates the schedule information and the position information with the position ID to correspond with each other. The program is stored in the database and the program is terminated at step 295.

Next, when the schedule information acquired in step 202 does not include a telephone number but includes address information, and the above-mentioned retrieval using the telephone number in step 206 as a keyword is applicable. A case will be described in which there is no information to be specified, but the schedule information includes address information.

First, the case where the schedule information does not include the telephone number but the address information is included will be described. In step 204, the information center 40 returns "No".
Then, in step 218, it is determined whether address information is included in the acquired schedule information in step 218.

In this case, since the acquired schedule information includes the address information, the information center 40 makes a “Yes” determination at step 218 and proceeds to step 220.
Then, the location search means 52 is used to search the map information database 54 for data using address information as a keyword. Then, the information center 40 proceeds to step 222 and determines whether or not there are more than one search result.

In this case, if there is only one search result, the information center 40 makes a “No” determination at step 222 to proceed to step 224, and at step 224, is there only one search result? It is determined whether or not, and further, in the step 224, it is determined as “Yes” and the above-mentioned step 21
2, 214 is executed. As a result, the information center 40
Acquires position information from the map information database 54 based on the address information, attaches the position ID to the position information, and
After associating the schedule information with the position information by D, the process proceeds to step 295 to end this program once.

On the other hand, if there are two or more search results during the execution of step 222, the information center 40 makes a “Yes” determination at step 222 and proceeds to step 21.
6, the user is made to select an appropriate one from a plurality of search results, and then the schedule information and the selected position information are associated with each other by the assigned position IDs in steps 212 and 214, and then the process proceeds to step 295. Then, this program ends.

Similarly, if there is no information corresponding to the search using the telephone number as a keyword in step 206, but the schedule information acquired in step 202 includes address information, the information center 40 is determined as “No” in step 210 and step 218
After that, the process proceeds to the step 220 and thereafter to acquire the position information based on the address information, assign the position ID to the position information, and associate the schedule information with the position information by the position ID, and then the step 295. Go to and end this program.

Next, when neither the telephone number nor the address information is included in the schedule information acquired in step 202, but the facility name information is included, and the address in step 220 described above. A case will be described in which there is no relevant information for a search using information as a keyword, but the schedule information includes information on a facility name.

First, the case where the schedule information does not include the telephone number and the address information but includes the facility name information will be described. The information center 4
0 is "No" in both steps 204 and 218.
Then, in step 226, it is determined in step 226 whether the facility name information is included in the acquired schedule information.

In this case, since the acquired schedule information includes the facility name information, the information center 40
Determines “Yes” in step 226, and determines in step 2
Proceeding to 28, a data search using the facility name information as a keyword is performed on the map information database 54 by using the point search means 52. Then, the information center 40 proceeds to step 230 and determines whether or not there are more than one search result.

At this time, if there is only one search result,
The information center 40 determines “No” in step 230, proceeds to step 232, determines in step 232 whether there is one search result, and further determines in step 23.
In Step 2, the above-mentioned step 212
Step 214 is executed. As a result, the information center 40 acquires the position information from the map information database 54 based on the facility name information, assigns the position ID to the position information, and outputs the same position I.
After associating the schedule information with the position information by D, the process proceeds to step 295 to end this program once.

On the other hand, if there are two or more search results during the execution of step 230, the information center 40 makes a “Yes” determination at step 230 and proceeds to step 21.
6, the user is caused to select appropriate information from a plurality of search results, and then the schedule information and the selected position information are associated with each other by the position ID provided in steps 212 and 214, and then the process proceeds to step 295. Exit this program once.

Similarly, when the information corresponding to the search using the address information in step 220 as a keyword does not exist, but the schedule information acquired in step 202 includes the facility name information, the information is displayed. Center 4
If 0 is determined as “No” in step 224, step 2 is performed.
After 26, the schedule information and the position information are associated with each other by the position ID, and the process proceeds to step 295 to end this program once.

Finally, when the schedule information acquired in step 202 does not include any of telephone number information, address information, and facility name information, the information center 40 performs all steps 204, 218, 226. When it is determined to be "No" in the step, the process proceeds to step 295 to end this program once. If there is no corresponding information for the search using the facility name as a keyword in step 228, the information center 40 proceeds to steps 230, 232.
At step 295, the program is terminated once.

As described above, according to the first position ID associating method, the position information is acquired based on the position related information (excluding the position ID) included in the schedule information, and the acquired position information is used. The schedule information is associated with the location ID.

(Second Location ID Association Method) Next, regarding the second location ID association method, a program executed by the information center 40 each time a predetermined time elapses or when a new schedule is input is shown in a flowchart. This will be described with reference to the illustrated FIG. The second position ID association method is step 226 of the program of FIG.
Alternatively, it may be configured to be executed while proceeding from step 232 to step 295.

The second position ID associating method obtains the position information from the position related information included in the schedule information of the participant specified by the participant information included in the schedule information shown in FIG. To the position information in the schedule information database 42 and the position information in the position information database 45 are associated with each other. Here, the participants are, for example,
Meeting attendees if the schedule is a meeting,
If it is lunch, it is the person who is planning to have lunch together, and if it is a party, it is the attendees of the party. Note that FIG.
2, the same steps as those shown in FIG. 2 are designated by the same reference numerals and detailed description thereof will be omitted.

More specifically, the information center 40 starts the processing of this program from step 400 at a predetermined timing, proceeds to step 402, and identifies from the information stored in the schedule information database 42. Get personal schedule information. Next, the information center 40 proceeds to step 404 to determine whether the acquired schedule information includes the participant information (actually the participant ID). In this case, if the participant information is not included at all, the information center 40 immediately proceeds to step 495 to end this program.

On the other hand, if the schedule information includes the participant information, the information center 40 makes a “Yes” determination at step 404 to proceed to step 406, and at step 406, participates in the acquired schedule. Whether or not there is only one person is determined from the number of participant IDs entered. At this time, if there is only one participant (only one participant ID is entered), the information center 4
In step 406, 0 is determined as “Yes” and the process proceeds to step 408. In step 408, the start date and time t1 and the end date and time t2 are read from the acquired schedule information, and the process proceeds to step 412.

On the other hand, when step 406 is executed,
If there are a plurality of participants, the information center 40 proceeds to step 410 and executes a process for allowing the user to identify one of the participants. Specifically, the information center 40 reads out the name of the participant identified by the participant ID from the participant information database 44, and outputs the participant name and an appropriate participant name from the participant name to the user. An instruction signal for displaying the comment for selecting the display means 22 on the display means 22 is transmitted to the vehicle-mounted terminal 20.

Thus, when the user specifies one of the participant names by the input means 24, the specified participant name is transmitted from the vehicle-mounted terminal 20 to the information center 40, and the information center 40 proceeds to the above-mentioned step 408. And the start date and time t1 and end date and time t2 of the acquired schedule.
From the schedule information, then step 4
Proceed to 12.

When the information center 40 proceeds to step 412, in the time zone from the start date / time t1 to the end date / time t2 of the participant (the participant selected in step 410 when there are a plurality of participants). The schedule information of all the set schedules is acquired from the schedule information database 42. Specifically, the schedule information database 42 is searched with the participant ID, the start date and time t1, and the end date and time t2 as keywords to acquire the relevant schedule information of the participant.

The information center 40 then proceeds to step 414.
Then, it is determined whether there are two or more (plural) schedules of the participants obtained from the search result. Then, when there are two or more schedules of participants, the information center 40 proceeds to step 416 and determines that each time zone of the plurality of schedules and the time zone specified by the start date and time t1 and the end date and time t2 are the most. Decide to adopt a long overlapping schedule and proceed to step 418.

On the other hand, when step 414 is executed,
If there is no more than one participant schedule, the information center 40 proceeds to step 420 and determines whether there is one participant schedule. Then, if there is one participant information, the information center 40 makes a “Yes” determination at step 420 to proceed to step 422, determines to adopt this schedule at step 422, and proceeds to step 418.

On the other hand, when step 420 is executed,
If there is only one participant information, it means that there is no corresponding participant schedule, so the information center 4
If 0, the process proceeds to step 495 to end this program.
Such a situation occurs when, for example, another person informs that he / she will participate in the target schedule by e-mail or the like, and then changes the schedule, and does not notify the change result.

Next, in step 418, the information center 40 determines whether or not the position ID is present in the schedule information of the participants who are decided to be adopted. At this time, if the position ID exists, the information center 40 determines “Yes” in step 418 and proceeds to step 212. In step 212, the user confirms that the position information associated with the position ID is correct. Then, the process proceeds to step 214, where the position information attached to the position ID is acquired, and a new position ID is given to it.
After the acquired schedule information and the position information to which a new position ID has been added are associated with the same position ID and stored in the corresponding databases 42 and 45, the process proceeds to step 495 to end this program once.

When step 418 is executed,
When the location ID does not exist in the schedule information of the participant who has been decided to be adopted, the information center 40 performs steps 204 to 232 (processing similar to the program shown in FIG. 2) to schedule the participant. The location information of the destination of the schedule is acquired by any of the telephone number information, the address information, and the facility name information included in the information.
Then, after confirming in step 212, the process proceeds to step 214, in which a position ID is added to the acquired position information, and the acquired schedule ID and position information having the added position ID are obtained with this position ID. Associating and ending this program in step 495.

As described above, according to the second position ID associating method, the position information is obtained from the position related information included in the schedule information of the participant specified by the participant information included in the schedule information. The position information is acquired and given a position ID, and the schedule information in the schedule information database 42 and the position information in the position information database 45 are associated with each other by the position ID.

(Third position ID associating method) Next, regarding the third position ID associating method, a program executed by the information center 40 every time a predetermined time elapses or when a new schedule is input is shown in a flowchart. This will be described with reference to FIG. Note that, in FIG. 5, steps that perform the same processing as the steps shown in FIG. 2 or FIG. 4 are assigned the same reference numerals as those in FIG. 2 or FIG. 4, and detailed description thereof will be omitted.

In the third position ID associating method, the position information corresponding to the schedule is also obtained by the first and second position ID associating methods immediately before the start date and time of each schedule (before a predetermined time). (So position I
If D) is not obtained, it is assumed that the participants of the same schedule will be facing the destination of the same schedule and will be in a position very close to the destination of the same schedule, and the participant's mobile phone The position of the same participant is specified using the telephone, and the position information of the destination corresponding to the same schedule is acquired by this, the position ID is attached to this position information, and the position information in the schedule information database 42 is added. This is a method of associating the schedule information with the position information in the position information database 45.

Specifically, the information center 40 determines whether or not a position ID is given to the schedule just before the start date and time (time) of the arbitrary schedule, and gives the position ID. If not, the processing of this program is started from step 500. Then
The information center 40 proceeds to step 502 to acquire the schedule information that is the factor for starting the program from the schedule information database 42, and proceeds to step 404 to add the participant information (actually, the participant ID to the acquired schedule information). ) Is included.
In this case, if the participant information is not included at all, the information center 40 immediately proceeds to step 595 to end this program.

On the other hand, if the schedule information includes the participant information, the information center 40 makes a “Yes” determination at step 404 to proceed to step 406, where the schedule of the acquired schedule information is obtained at step 406. Whether or not there is only one participant is determined from the number of participant IDs entered. At this time, if the number of participants is one, the information center 40 proceeds to step 504.
If a plurality of participants exist at the time of executing step 406, the information center 40 proceeds to step 410 to let the user select one of the participants, and then proceeds to step 504.

In step 504, the information center 40 retrieves and acquires the personal information (name, address, mobile phone number, etc.) of the participant from the personal information database 43,
In step 506, the position (longitude, latitude) of the mobile phone having the same mobile phone number is acquired from the mobile phone center 60 from the acquired mobile phone number. This position is
Under the assumption that the participants are acting according to the schedule, it is considered that the participants are extremely close to the destination or have arrived at the destination, so the destination ( Neighborhood) position.

The information center 40 then proceeds to step 50.
8, the position information (the data set) corresponding to the acquired position of the mobile phone is stored in the map information database 5
4, the position ID is given to this position information, and the acquired position information in the schedule information database 42 and the position information with the position ID in the position information database 45 are associated with this position ID.

As described above, according to the third position ID associating method, based on the position of the participant of the schedule immediately before the start date and time of the schedule, the position information of the movement destination (place) of the schedule is obtained. Then, the location ID is added to this, and the schedule information and the location information are associated with each other by the location ID.

(Sequential destination automatic setting route guidance method) Next, when the user of the vehicle starts the engine of the vehicle or when the user performs a predetermined operation using the input means 24. Next, a route guidance method in which the vehicle-mounted terminal 20 acquires necessary information from the information center 40 and automatically performs route guidance to the destination of the next schedule will be described. Since this route guidance method is a method in which destinations are automatically set sequentially and route guidance is performed based on a user's request, it is called a route guidance method by sequential destination automatic setting.

Specifically, when the user of the vehicle starts the engine of the vehicle, or when the user of the vehicle starts the input means 24.
When a predetermined operation is performed using, the in-vehicle terminal 20 starts the process from step 600a shown in FIG.
At 2a, a request signal for confirming the presence / absence of the user's schedule is transmitted to the information center 40 together with the user's ID.

On the other hand, when the information center 40 receives the confirmation request signal for the presence / absence of the schedule, step 600
In step 602b subsequent to b, the current date and time is acquired, and the process proceeds to step 604b to set the schedule (the next schedule (one time after)) that comes next in time from the acquired current date and time. It is acquired from the schedule information database 42. Next, the information center 40 proceeds to step 606b, and determines whether or not the position ID is included in the schedule acquired in step 606b.

At this time, if the position ID is not included, the information center 40 makes a "No" determination at step 606b to proceed to step 608b, at which step 608b.
At step 610b, the in-vehicle terminal 20 is answered that there is no position ID (that is, position information including the route and latitude) in the next schedule, and the program ends. On the other hand, if the location ID is included in the schedule acquired in step 604b, the information center 40 determines “Yes” in step 606b and determines 612b.
Then, in step 612b, the reply “there is a position ID in the next schedule” and the position specified by the position ID (ie, destination information represented by latitude and longitude) are sent to the in-vehicle terminal 20. Then, the program is terminated at step 614b.

At this time, the in-vehicle terminal 20 performs step 604.
The reception process is performed in step a.
Monitors whether or not the reception is completed. Therefore, step 608b or step 6 of the information center 40
When the process of 12b is completed, the in-vehicle terminal 20 performs step 6
It is determined to be “Yes” in 06a, the process proceeds to step 608a, and in step 608a, the position I is set in the next schedule.
It is determined whether or not there is D. Then, if there is no position ID in the next schedule, the in-vehicle terminal 20 performs step 608.
When it is determined to be "No" at a, the process proceeds to step 695a, and at step 695a, this program ends.

On the other hand, if the next schedule has a position ID, the in-vehicle terminal 20 makes a "Yes" determination at step 608a.
Then, the process proceeds to step 610a to confirm with the user whether or not the user desires to acquire a route from the information center 40. Specifically, the vehicle-mounted terminal 20 displays the comment for the confirmation on the display unit 23.

Based on this display, when the user performs an operation indicating that the user desires to obtain a route by the input means 24, the in-vehicle terminal 20 determines “Yes” at step 610a, proceeds to step 612a, and at step 612a. The position (destination information) specified by the transmitted position ID is set as the destination in the route guidance. And the in-vehicle terminal 2
In step 614a, 0 transmits the current position of the own vehicle and the destination to the information center 40, and requests the information center 40 to distribute information necessary for the guide route.

When the information center 40 receives the distribution request for this guide route, it proceeds from step 600c to step 602.
In step 602c, the route from the current position (departure point) of the vehicle to the destination is searched using the data in the map information database 54 and the traffic information database 55, and information about the searched route is displayed. In-vehicle terminal 20
To deliver to.

The vehicle-mounted terminal 20 is based on the distributed information about the searched route, and the sounding means 22 and the display means 23.
Is used to provide route guidance, and in step 616a, it is monitored whether the vehicle has reached the destination. Then, the in-vehicle terminal 20 performs route guidance by repeatedly executing step 614a until the vehicle reaches the destination,
When the vehicle reaches the destination, the process proceeds to step 695a to end the program.

As described above, according to the route guidance method by the sequential destination automatic setting, the place (movement destination) of the next schedule is automatically set as the destination data for route guidance. The user sets the same destination to the in-vehicle terminal 2
There is no need to enter 0 separately. In addition, the information center 40
Based on the map data of the map information database 54 on the side where the latest traffic information can be easily possessed and the traffic information data of the traffic information database 55 which obtains the latest traffic information from the traffic information center 70. Since route guidance is executed, appropriate route guidance according to the current situation is performed.

As described above, according to the first embodiment of the present invention, based on the own schedule information (the position-related information thereof), the participant's schedule information, and the position of the participant's mobile phone, etc. The location information specifying the location (destination) of the schedule is acquired, the schedule information and the location information are linked by the location ID unique to the location information, and the linked schedule information and location information are route-guided. To use. Therefore, even if the user does not input the latitude and longitude of the place of the schedule, route guidance to the place is automatically performed.

(Second Embodiment: Circular Route Guidance Method) Next, a second embodiment of the information providing system according to the present invention will be described. In the second embodiment, for example, when the engine is first started on a certain day, a patrol route according to the schedule is obtained according to the schedule information, and then the patrol route is automatically updated while updating the patrol route. It is something to do. The patrol route guidance method of the second embodiment can be adopted instead of or in addition to the route guidance method of the sequential automatic destination setting of the first embodiment.

First, when the user starts the engine for the first time on any day and the communication performed with the information center 40 is normal, a detailed description will be started.
The in-vehicle terminal 20 performs step 700a at a predetermined timing.
The process is started from step 702a, and the routine proceeds to step 702a, where it is determined whether or not the present time is the first operation on any day (today), that is, whether or not the engine is started for the first time today.

According to the above-mentioned assumption, the current time is the first operation today, so the in-vehicle terminal 20 makes the step 70
It is determined to be "Yes" in 2a and the process proceeds to step 704a. In step 704a, the user ID and the information about the current location of the vehicle are transmitted to the information center 40, and
The information center 40 is requested to deliver information about the patrol route. Then, the in-vehicle terminal 20 starts time counting by the timer T1 in step 706a, and continues in step 708.
At a, it waits for a response from the information center 40.

On the other hand, the information center 40 starts the process from step 700b shown in FIG. 7 and proceeds to step 702b. At step 702b, the information center 40 waits for a request for distribution of information on the patrol route from the vehicle-mounted terminal 20 and then continues. 70
At 4b, it is adapted to monitor whether or not there is a request for distribution of information regarding the patrol route.

Therefore, step 704a of the vehicle-mounted terminal 20
In response to the request for distribution of information about the patrol route, the information center 40 returns “Yes” in step 704b.
Then, the process proceeds to step 706b to acquire the current time (date and time). The information center 40 then proceeds to step 7
In step 708b, the today's schedule information after the current time is acquired from the schedule information database 42 based on the user ID and the current time acquired in step 708b, and in the subsequent step 710b, the current time and after. It is determined whether the position ID is included in all the schedules of today.

Then, the information center 40 makes a "Yes" determination at step 710b to proceed to step 712b when the position ID is included in all the schedule information for today after the current time. On the other hand, if any of today's schedule information after the current time does not include the position ID, the information center 40 proceeds to steps 714b to 720b to acquire the position information, and then the position information. Is assigned a position ID, and the position information acquired by the position ID is associated with the corresponding schedule information.

Specifically, in step 714b, the information center 40 makes a request for setting position-related information for the schedule information that does not include the position ID (that is, the position ID-unset schedule). In-vehicle terminal 2
Send to 0. At this time, the information center 40 determines the location ID
Schedule ID, name, contents of unset schedule,
The start date and time and the end date and time are transmitted to the vehicle-mounted terminal 20. Then, the information center 40 monitors whether or not there is a response (that is, a position information setting response) from the vehicle-mounted terminal 20 that the position related information is set for the position ID unset schedule in steps 716b and 718b.

At this time, the in-vehicle terminal 20 makes a step 708.
In step a, the timer T1 monitors whether or not the timer T1 has finished counting the predetermined time. If the timer T1 has not finished counting the predetermined time, the step At 712a, it is monitored whether or not there is a request for setting the position-related information for the position ID unset schedule, and at step 718a, whether or not there is a patrol route response, which will be described later, is monitored.

Therefore, when the information center 40 requests the onboard terminal 20 to set the position-related information for the position ID unset schedule by the processing of step 714b described above, the onboard terminal 20 makes the request at step 708a. Received as a response from 40. In this case, since the communication between the information center 40 and the vehicle-mounted terminal 20 is normally performed, the vehicle-mounted terminal 20 receives the response from the information center 40 before the timer T1 completes counting the predetermined time. Therefore, the in-vehicle terminal 20 returns “No” in step 710a.
Then, the process proceeds to step 712a, and the same step 712
At a, it is determined whether or not the received response is a request for setting position related information for a position ID unset schedule.

In this case, since the response from the information center 40 is a request to set the position-related information for the schedule for which the position ID is not set, the in-vehicle terminal 20 determines "Yes" in step 712a. Then step 714
Proceeding to step a, in step 714a, the user is allowed to input the position-related information required to acquire the position ID for the position ID unset schedule.

That is, the in-vehicle terminal 20 stores a part of the schedule information (schedule ID, name, contents, start date / time, end date / time) of the schedule whose position ID is not set,
A comment prompting the user to input position-related information (address, telephone number, facility name corresponding to the schedule) excluding the position ID is displayed on the display unit 23. Then, when the position-related information other than the position ID (not necessarily all) is input to the position ID unset schedule information, the vehicle-mounted terminal 20.
Transmits the position-related information input together with the schedule ID to the information center 40 in step 716a. After that, the in-vehicle terminal 20 returns to step 708a,
The state of waiting for a response from the information center 40 is entered.

At this time, the information center 40 proceeds to step 71.
6b and step 718b, it is monitored whether or not there is a setting response of the position-related information for the position ID unset schedule from the vehicle-mounted terminal 20.
Executes step 716a, step 718
When it is determined to be “Yes” in b, the process proceeds to step 720b,
In step 720b, the position information is acquired based on the position-related information transmitted from the vehicle-mounted terminal 20, the position ID is given to the position information, and the position information in the schedule information database 42 is acquired by the position ID. Associate with location information. Note that the process of step 720b follows any one of the above-described first to third position ID associating methods. Next, the information center 40 executes the step 7
Return to 10b. Then, such processing is repeated,
Location ID for all today's schedules after the current time
When the information is added, the information center 40 proceeds to step 710b.
Then, it is determined to be "Yes" and the process proceeds to step 712b.

When the information center 40 proceeds to step 712b, it sets the current location information of the vehicle acquired in step 702b as the current location (departure location) for route guidance,
In the following step 722b, the position of each destination of the today's schedule after the current time (the position identified by the position ID) is set as the transit point, and the destination position of the last schedule of the today's schedule is set. Set as the ground. The information center 40 then proceeds to step 72.
4b, using the data in the map information database 54 and the data in the traffic information database 55, a route connecting the set departure point, waypoint, and destination is searched, and the route searched in step 726b. Equidistant distance Lkm
The information necessary for guiding the route corresponding to the first Lkm is transmitted to the vehicle-mounted terminal 20. The response from the information center 40 is called a patrol route response.

At this time, the in-vehicle terminal 20 makes a step 708.
Since it is waiting for a response from the information center 40 at a,
When the information necessary for route guidance is received by executing step 726b, the process proceeds to step 710a, and since communication is normal, it is determined to be "Yes" in step 710a. Then, the in-vehicle terminal 20 determines whether the response from the information center 40 is a request for setting the position information for the position ID non-set schedule, and determines “No” in step 712 a In step 718a, it is determined whether or not the response from the information center 40 this time is a patrol route response.

The response from the information center 40 this time is a patrol route response. Therefore, the in-vehicle terminal 20 determines “Yes” in step 718a, proceeds to step 720a, and performs route guidance using the information obtained by the patrol route response in step 720a. Next, the vehicle-mounted terminal 20 proceeds to step 722a, acquires the average vehicle speed s of its own vehicle in the past Nkm in step 722a, and then acquires the average vehicle speed s of the own vehicle in the past Nkm in step 724a (for the 7 km portion). It is determined whether a value obtained by dividing the difference between the end position of the route and the current position (that is, the remaining guide route distance) by the average vehicle speed s is smaller than the predetermined time T2. When it is determined to be "No" in step 724a, it is determined that it is not necessary to acquire information necessary for a new guide route, and the process returns to step 720a to continue the route guidance.

On the other hand, when it is determined to be "Yes" in step 724a, the vehicle-mounted terminal 20 proceeds to step 726a and determines whether or not the end point of the route acquired by the patrol route response is the destination. At this moment, since the route guidance is just started, the judgment in step 726a is generally "No", so that the in-vehicle terminal 20 selects step 728a.
At, a signal requesting subsequent route information, a user ID,
Send information about your current location to the information center 40,
In the following step 730a, the time counting by the timer T3 is started, and in the steps 732a to 736a, the state of waiting for the subsequent route information response is entered.

At this time, the information center 40 proceeds to step 72.
In step 8b, the subsequent route information request is awaited, and the subsequent step 73
The current date and time is acquired at 0b, and it is determined at step 732b whether or not the current date and time is the next day. If the acquired date and time is not the next day, the information center 40 proceeds to step 734b, determines in step 734b whether there is a request for the subsequent route information, and if there is no request for the same route information. Step 72 again
The process of returning to 8b is repeatedly executed.

Therefore, when a signal requesting the subsequent route information is transmitted from the vehicle-mounted terminal 20, the information center 40
Determines “Yes” in step 734b, proceeds to step 736b, acquires today's schedule after the current time from the schedule information database 42, and continues to next step 738b for each movement of today's schedule after the current time. The destination position is set as the waypoint, and the destination position of the last schedule for today is set as the destination.

The information center 40 then proceeds to step 74.
0b, using the data in the map information database 54 and the data in the traffic information database 55, the route connecting the vehicle's current location, transit point, and destination is searched again, and the route searched in step 742b is searched. Equal distance Lk
After dividing into m and transmitting the information required for route guidance corresponding to the first Lkm to the vehicle-mounted terminal 20, the process returns to step 728b.

At this time, the in-vehicle terminal 20 performs step 732.
A state of waiting for the subsequent route information in a, monitoring whether or not the timer T3 has finished measuring a predetermined time in step 734a, and monitoring in step 736a whether or not the subsequent route information is acquired. It has become. Therefore, when the information center 40 executes the process of step 742b,
Since the in-vehicle terminal 20 has normal communication, step 734 is performed.
In step a, it is determined to be “Yes”, and also in subsequent step 736a, it is determined to be “Yes”, the process returns to step 720a, and the route guidance based on the received route information is continued.

Thereafter, the in-vehicle terminal 20 starts from step 720a.
736a is repeatedly executed, and the information center 40 repeatedly executes steps 728b to 742b. As a result, a route based on the latest map information and the latest traffic information is searched in step 740b, and route guidance according to the searched route is executed in step 720a.

After that, when the predetermined time has elapsed, the vehicle approaches the destination, so that the end point of the remaining guide route and the destination become equal. As a result, the in-vehicle terminal 20 performs step 726.
When it is determined to be “Yes” in a, the process proceeds to step 738a,
In step 738a, it is determined whether or not the current position of the vehicle has become the destination (whether the vehicle has reached the destination). When the vehicle has not reached the destination, the in-vehicle terminal 20
Returns to step 720a again to continue the route guidance. After that, when the vehicle reaches the destination, the in-vehicle terminal 20 determines “Yes” in step 738a and determines in step 7
The program proceeds to step 95a and the program is terminated at step 795a.

At this time, the information center 40 proceeds to step 7
Since 28b to 734b are repeatedly executed, when the current date and time becomes the next day, it is determined to be "Yes" in step 732b, the process returns to step 702b, and waits for the next patrol route request.

Note that the in-vehicle terminal 20 continues to wait for a response from the information center 40 for a predetermined period of time T1 or T3 or longer due to a failure in communication between the in-vehicle terminal 20 and the information center 40 or the like. Then, the vehicle-mounted terminal 20 determines “Yes” in step 710a or step 734a, proceeds to step 740a, and displays on the display unit 23 that an error has occurred. Further, when the engine is started more than once on any day, the in-vehicle terminal 20 proceeds to step 700.
When step 702a follows step a, the same step 702a
Is determined as “No” and the process proceeds to step 720a and thereafter,
Route guidance based on the received route information.

As described above, according to the second embodiment, when the engine is started for the first time on any day, each position of the schedule of the same day is acquired and the route corresponding to the position is automatically set. It Therefore, the user can move to the destination of each schedule without inputting the destination each time. In addition, since the route guidance at that time is performed along the route searched based on the latest map information and the latest traffic information, the user should move to the destination of each schedule via an appropriate route. You can

(Third Embodiment: Automatic Migration Schedule Generation Method) Next, a third embodiment of the information providing system according to the present invention will be described. In the third embodiment, when the user newly inputs a schedule into the vehicle-mounted terminal 20,
Or, if you change the existing schedule, enter the
The present invention relates to a method for automatically generating / correcting a movement schedule between a schedule before and after a changed schedule and the same input / changed schedule. Hereinafter, FIG. 8 to FIG.
A detailed description will be given with reference to 0.

When the user inputs a new schedule into the vehicle-mounted terminal 20 or changes the existing schedule, the information of this schedule is transmitted from the vehicle-mounted terminal 20 to the information center 40. As a result, the information center 40 starts the program shown in FIG. 8 from step 800,
In step 802, the newly input / changed schedule information is stored in the schedule information database 42. In the example shown in FIG. 10, the input / changed schedule is shown in (A).

The information center 40 then proceeds to step 804.
The position ID of the schedule information input / changed in step 804 (reference numeral (a) in FIG. 10).
Is set according to the above-described first and second position ID associating methods. Setting the position ID means that the movement destination (latitude, longitude) of the same schedule is specified.

Next, the information center 40 proceeds to step 806 and performs "automatic generation-at the same time as the input / changed schedule (that is, the time zone from the start date and time to the end date and time).
It is determined whether or not a "movement" schedule exists.
At this time, if the "automatic generation-movement" schedule already exists, the "automatic generation-movement" schedule is meaningless due to the input / changed schedule, and the information center 40 executes the step. At 808, the same “automatic generation-migration” schedule is deleted from the schedule information database 42, and the process proceeds to step 810. Further, at the time of executing step 806, if the “automatic generation-movement” schedule does not exist, the information center proceeds directly to step 810.

Next, the information center 40 proceeds to step 81.
At 0, the schedule information of the schedule set by the user before and after the input / changed schedule (hereinafter, referred to as “user-set schedule information”) is acquired from the schedule information database 42, and at the following step 812, Whether the position information (indicated by symbol (b) in FIG. 10) is included in the schedule information (indicated by symbol (B) in FIG. 10) of the user-set schedule immediately before the entered / changed schedule. To determine. Then, if the position ID is not included, in step 814, the previous user setting schedule is designated, and in step 816, the position ID for the schedule information of the designated schedule is set. This is performed according to the above-described first and second position ID associating methods, and then the process proceeds to step 818. If the position ID is included in the schedule information of the user-set schedule immediately before the input / changed schedule at the time of executing step 812, the information center 40 immediately proceeds to step 818.

Next, the information center 40 proceeds to step 81.
8, the position determined by the position ID included in the schedule information of the user-set schedule (B) immediately preceding the input / changed schedule (A), and the input /
The position determined by the position ID included in the schedule information of the changed schedule (A) is used as the starting point in the schedule information of the “automatic generation-movement” schedule (indicated by reference numeral (C) in FIG. 10) generated this time. ,
And the destination respectively, and the following step 820
At, a route between the starting point and the destination is searched using the data of the map information database 54 and the traffic information database 55.

Next, the information center 40 proceeds to step 822 to set the schedule information of the immediately preceding user set schedule (B) as the move source schedule information, and to input and change the schedule (A).
Set the schedule information of as the destination schedule information.

Next, the information center 40 proceeds to step 824, where the user-set schedule (B) immediately before the input / changed schedule (A) and the input / changed schedule (A) are set. An "automatic generation-movement" schedule (C) between is generated according to the program shown in FIG.

That is, the information center 40 starts the process from step 900, and creates the information frame of the "automatic generation-movement" schedule information in step 902. More specifically, the information center 40 uses the schedule I
D, and the route ID are assigned so as not to overlap with other IDs, and the schedule ID of the "automatic generation-move" schedule to be created is the assigned schedule ID, the notification status is not notified, the content is being moved, and the type Automatic generation-movement, a vehicle as a moving means, and a route ID as the given route ID.

Next, the information center 40 proceeds to step 904 and creates a route information frame in step 904. The route information frame is stored in the route information database 46, and is indicated by the symbol (D) in FIG. Specifically, the information center 40 determines that the route I given in step 902 is used.
D and the assigned schedule ID are respectively set as the route ID and the schedule ID of the route information frame, and the process, the required time, the number of route links of the route information frame are set according to the route search result of step 820. Set route information including a link ID and the like. After that, the information center 40 proceeds to step 906 and stores the route frame in the route information database 46.

The information center 40 then proceeds to step 908.
In step 908, the name 1 included in the transfer source schedule information is set in the form of “name 1 →” in the name column of the “automatic generation-transfer” schedule information, and the schedule of the transfer source schedule information is set. The ID is set in the starting point schedule ID field of the “automatic generation-movement” schedule information.

Subsequently, the information center 40 proceeds to step 910.
In step 910, predetermined items are set in predetermined items of the “automatic generation-movement” schedule based on the movement destination schedule information. Specifically, the information center 40 sets the date and time before the start date and time included in the destination schedule information by a predetermined time t1 as the end date and time of the "automatic generation-movement" schedule. The column of the name set in the form of "name 1 →" in the "automatic generation-movement" schedule is changed to "name 1 →
Change to the form of "Name 2" and set. Here, the name 2 is the name included in the destination schedule information. The information center 40 also sets the schedule ID of the destination schedule information as the end point schedule ID of the “automatic generation-migration” schedule information.

The information center 40 then proceeds to step 912.
In step 912, the date and time before the end date and time of the “automatic generation-movement” schedule by the required time included in the route information frame is set as the start date and time of the same “automatic generation-movement” schedule. At 914,
The “automatic generation-migration” schedule generated as described above is stored in the schedule information database 42, and the process proceeds to step 826 via step 995.

The information center 40 then proceeds to step 826.
Through 838, the schedule information of the “automatic generation-movement” schedule between the input / changed schedule and the user-set schedule that is one time after the input / changed schedule is set in step 812 described above. ~
After generating the schedule information in the same manner as 824 and saving the schedule information of the generated “automatic generation-movement” schedule in the schedule information database 42, this program ends in step 895.

As described above, according to the third embodiment, when the user newly inputs a schedule or changes an existing schedule, the schedules before and after the input / changed schedule, Same input
A movement schedule to / from the changed schedule is automatically generated / modified. Therefore, the user can always confirm what kind of action should be taken at present. Further, according to the “automatic generation-movement” schedule, for example, when the in-vehicle terminal 20 is configured to notify the user that it is the departure time at the departure date and time, and thereafter route guidance is performed, the user can You can arrive at the destination of each schedule without being late for the schedule.

(Fourth Embodiment: Departure Time Notification Method Based on Route Calculation at Information Center) Next, a fourth embodiment of the information providing system according to the present invention will be described. This 4th
In the embodiment, for example, the “automatic generation-movement” schedule information generated according to the third embodiment is corrected based on the traffic situation that changes from moment to moment, and the departure time is notified to the user based on the corrected movement schedule information. Is a method of notifying that the arrival has come. Hereinafter, a specific description will be given with reference to FIG.

The information center 40 is adapted to repeatedly execute the program shown by the flowchart of FIG. 11 every time a predetermined time elapses. Therefore, at a predetermined timing, the process is started from step 1100, and the process proceeds to step 1102 to acquire the current date and time. Next, the information center 40 proceeds to step 1104, and in step 1104, acquires information on the next moving schedule (hereinafter, referred to as the “moving” schedule) based on the current date and time from the schedule information database 42. .

Next, the information center 40 proceeds to step 110.
In step 1106, it is determined whether or not the next “movement” schedule is present. If the next “movement” schedule is not present, the operation proceeds to step 1195 to end this program. On the other hand, at the time of determination in step 1106, if the next “movement” schedule exists, the information center 40 returns “Yes” in step 1106.
Then, the process proceeds to step 1108, and step 110
At 8, it is determined whether or not the transportation means of the next "movement" schedule is a car.

At this time, if the moving means of the next "moving" schedule is not a car, the information center 40 proceeds to step 119.
Go to step 5 to end this program. On the other hand, step 1
At the time of the determination of 108, if the means of transportation of the next “movement” schedule is a car, the information center 40 determines at step 110.
When it is determined to be “Yes” in step 8, the process proceeds to step 1110,
In step 1110, the position ID of the schedule of the movement source of the next “moving” schedule is acquired based on the starting point schedule ID of the next “moving” schedule, and the position (latitude, longitude) specified by the same position ID is set as the departure point. Set as. Next, the information center 40 proceeds to step 1112,
In step 1112, the position ID of the destination schedule of the next “moving” schedule is acquired based on the end point schedule ID of the next “moving” schedule, and the position (latitude, longitude) specified by the same position ID is set as the destination. Set as.

The information center 40 then proceeds to step 111.
4, the route search from the starting point to the destination is performed based on the map data in the map information database 54 and the traffic information in the traffic information database 55 in step 1114, and the required time t is predicted. Perform processing to Then, the information center 40 proceeds to step 1116, and in step 1116, the start date and time of the schedule having the schedule ID indicated by the end point schedule ID (that is, the start date and time of the schedule existing next to the target next “moving” schedule). ) Is subtracted from the predicted required time t as the start date and time of the same “movement” schedule, and this is stored in the schedule information database 42.

Next, the information center 40 proceeds to step 1118.
Then, in step 1118, the route information corresponding to the next “moving” schedule is updated with the information on the route searched in step 1114 and stored in the route information database 46. Regarding the route information, (D) of FIG.
As shown in. Subsequently, the information center 40 proceeds to step 1120, and at step 1120, the next “move” is performed.
Set the notification status of the schedule to Not notified, and step 1
In step 122, the start date and time of the next “movement” schedule is acquired. This start date and time is the start date and time obtained in the previous step 1116.

The information center 40 then proceeds to step 112.
In step 1124, it is determined whether the time obtained by subtracting the current date and time from the start date and time of the next “movement” schedule is equal to or shorter than the predetermined time T or not. At this time, if the time obtained by subtracting the current date and time from the start date and time of the next "movement" schedule is not less than or equal to the predetermined time T, the information center 40 proceeds to step 1195 and ends this program once. On the other hand, when the time obtained by subtracting the current date and time from the start date and time of the next “movement” schedule is less than or equal to the predetermined time T, the information center 40 proceeds to step 1126 and step 112.
In step 6, a notification sentence is created to notify the user that the user should depart because the departure time has arrived (the departure date is approaching), and the process proceeds to step 1128 to acquire contact information from the personal information database 43. The contact information to be acquired includes the contact information of the mobile terminal of the user such as the mail address of the mobile phone, the mail address of the mobile computer, and the ID of the vehicle-mounted terminal 20.

The information center 40 then proceeds to step 113.
0, send the created notification text to the mobile terminal of the contact identified by the contact information, set the notification status of the next “movement” schedule to “notified” in step 1132, and proceed to step 1195. Exit this program once.

As described above, according to the fourth embodiment, the next "movement" schedule is updated based on the latest traffic information (and the latest map information) at every predetermined time, and the next movement is made. At a point in time that is a predetermined time T before the date and time to depart ahead, the contact information of the mobile terminal such as the mobile phone of each individual is notified that the time to depart has arrived. As a result, even if the traffic condition changes (for example, traffic jam occurs due to an accident or the like), the user can reliably reach the destination of the next schedule in time. The steps 1101 to 1116 correspond to departure date and time determining means, and the steps 1120 to 1130 correspond to information providing means.

(Fifth Embodiment: Method of Automatically Generating Travel Schedule and Stayable Schedule) Next, a fifth embodiment of the information providing system according to the present invention will be described.
In the fifth embodiment, when the user newly inputs a schedule into the in-vehicle terminal 20, a movement schedule between a preset schedule immediately before the input schedule and the input schedule and a stayable schedule are automatically calculated. Method to generate dynamically. Here, the stayable schedule refers to staying at the location of the finished schedule during a period from the end of a certain user-set schedule to the start of moving to the location (destination) of the next user-set schedule. It is a schedule that shows what can be done. Hereinafter, a specific description will be given with reference to FIGS. 12 and 13.

When the user inputs a new schedule through the vehicle-mounted terminal 20, the vehicle-mounted terminal 20 transmits the schedule information to the information center 40. As a result, the information center 40 executes the program shown in FIG.
Starting from 0, the process proceeds to step 1202, and the newly input (received) schedule is input to the schedule information database 42. This newly input schedule is shown as the currently input schedule in FIG.

The information center 40 then proceeds to step 120.
In step 1204, the position ID for the newly input schedule is set according to the above-described first and second position ID associating methods. Location ID
Setting of means that the position (latitude, longitude) of the movement destination of the schedule is specified. Subsequently, the information center 40 proceeds to step 1206, and at step 12
At 06, the schedule information other than the movement (including stayable) schedule immediately before the input schedule, that is, the schedule information of the schedule already set by the user is acquired from the schedule information database 42. This schedule is shown as a user preset schedule in FIG. 10, and will be referred to as “schedule * 1” below for simplicity.
To call.

Next, the information center 40 proceeds to step 120.
In step 8, the position determined by the position ID of the schedule * 1 is set as the starting point, and in step 1210, the position determined by the position ID of the input schedule is set as the destination. The information center 40 then proceeds to step 1212.
In the next step 1214, the route information from the starting point to the destination is set in the map information database 54 by setting a time that is a predetermined margin time tm1 before the starting date and time of the input schedule as the arrival target date and time. And the required time ta is calculated based on the data of the traffic information database 55.

The information center 40 then proceeds to step 12
In step 16, the date and time before the target arrival date and time by the required time ta is set as the departure required date and time (the date and time when it is necessary to depart), and in step 1218, a predetermined margin time tm2 before the departure required date and time. It is determined whether the time is after the end date and time of schedule * 1. At this time,
If the time point before the required departure date and time by the predetermined margin time tm2 is not after the end date and time of the schedule * 1, it means that the vehicle must depart before (or immediately after) the end of the schedule * 1. In this case, the information center 40 makes a “No” determination at step 1218 to proceed to step 1220, and at step 1220 notifies the vehicle-mounted terminal 20 that the newly input schedule has not been established. , And then returns to step 1202.

On the other hand, at the time of determination in step 1218, if the time point before the departure date and time by the predetermined margin time tm2 is after the end date and time of the schedule * 1,
The information center 40 makes a “Yes” determination at step 1218 to proceed to step 1222, whereat step 1222
Between the end date and time of schedule * 1 and the time that is a margin time tm2 before the required departure date and time, the “stayable schedule (“ automatic generation-stayable ”schedule)”
Information is generated and this information is stored in the schedule information database 42 (see FIGS. 13 and 20). Next, the information center 40 proceeds to step 1224, and in step 1224, the required departure date and time (from the margin time t
Information of the movement schedule (“automatic generation-movement” schedule) is generated between the time m2 before) and the start date and time of the input schedule (see FIG. 13), and this information is stored in the schedule information database 42. It is stored in the route information database 46. As described above, the movement schedule and the stayable schedule are automatically set.

Next, a method for automatically changing (updating) these schedules in order to cope with changes in traffic conditions after the travel schedule and stayable schedule are set once is shown in the flowchart of FIG. Description will be made with reference to the program shown. Information center 40
Executes the program shown in FIG. 14 every time a predetermined time elapses.

First, it is necessary to change the travel schedule and the stay schedule due to changes in traffic conditions, but if the schedule is satisfied (without delaying to the position of the next schedule other than the travel and stayable schedule) The information center 40 starts the process from step 1400 at a predetermined timing and proceeds to step 1402 to acquire the current date and time. Next, the information center 40 executes step 1404.
Next, the information of the "automatic generation-movement" schedule (hereinafter, referred to as the next "automatic generation-movement" schedule) that arrives next is acquired from the schedule information database 42, and the process proceeds to step 1406 to proceed from the current date and time. Whether or not the acquired "automatic generation-movement" schedule starts before the predetermined time t3 elapses (the next "automatic generation-movement").
It is determined whether or not the start date and time of the "movement" schedule is before the predetermined time t3 has elapsed from the current date and time).

At this time, if the next "automatic generation-move" schedule does not start before the predetermined time t3 has elapsed from the current date and time, the information center 40 determines "No" in step 1406, Proceed to 1495 to end this program once. On the other hand, if the next "automatic generation-move" schedule starts before the predetermined time t3 has elapsed from the current date and time (that is, the move start date and time is approaching and the time comes within the time t3 from the present time), the information The center 40 determines “Yes” in step 1406, proceeds to step 1408, and determines whether or not the moving means of the next “automatic generation-movement” schedule is a car. At this time, if the moving means of the next "automatic generation-movement" schedule is not a car, the information center 40 makes a "No" determination at step 1408 to proceed to step 1495 to end this program once. On the other hand, if the means of transportation for the next “automatic generation-movement” schedule is a car, the information center 40 determines “Yes” in step 1408, and proceeds to step 1
Proceed to 410.

In step 1410, the information center 40 moves to a schedule immediately before the next "automatic generation-movement" schedule and schedules other than stayable (hereinafter, schedule *
It is called 2. The position specified by the position ID of) is set as the starting point, and in the following step 1412, the next "automatic generation-
Position I of a schedule (hereinafter referred to as schedule * 3) other than the movement and stay after the "movement" schedule.
The position specified by D is set as the destination. And
The information center 40 proceeds to step 1414, sets a time earlier than the start date / time of the schedule * 3 by the margin time tm1 as the arrival target date / time, and in the next step 1416, searches for a route from the set departure point to the destination. Is performed based on the data in the map information database 54 and the traffic information database 55, and the required time ta is calculated.

Next, the information center 40 proceeds to step 14
Proceeding to step 18, the date and time before the target arrival date and time by the required time ta is set as the departure required date and time, and step 1420 is performed.
Then, it is determined whether or not the time point before the departure required date and time by the predetermined margin time tm2 is after the end date and time of the schedule * 2. At this time, if the time point before the departure required date and time by the predetermined margin time tm2 is not after the end date and time of the schedule * 2, the information center 40 proceeds to step 142.
It is determined to be “No” at 0 and the process proceeds to step 1422. At step 1422, it is determined whether or not an “automatic generation-stay available” schedule exists immediately before the next “automatic generation-movement” schedule. If there is an "automatic generation-stayable" schedule immediately before the next "automatic generation-movable" schedule, the process proceeds to step 1424 to delete the "automatic generation-stayable" schedule. Next, the information center 40 notifies the in-vehicle terminal 20 that the schedule has not been established in step 1426, and then temporarily terminates this program in step 1495.

On the other hand, at the time of the determination at step 1420, if the time point before the departure required date and time by the predetermined margin time tm2 is after the end date and time of the schedule * 2,
The information center 40 makes a “Yes” determination at step 1420 to proceed to step 1428, and at step 1428 of the information center 40.
And in the subsequent step 1430, the next "automatic generation-movement"
If the "automatically generated-stayable" schedule exists immediately before the schedule, the "automatically generated-stayable" schedule is deleted.

Next, the information center 40 proceeds to step 14
Proceeding to 32, an "automatic generation-stayable" schedule is generated between the end date and time of the schedule * 2 and the time before the departure time and date by the margin time tm2, and this is stored in the schedule information database 42. Next, the information center 40 proceeds to step 1434, where the margin time tm2 is calculated from the necessary departure date and time.
Between the previous date and time and the start date and time of schedule * 3, an "automatic generation-move" schedule is generated, and this is saved in the schedule information database 42, and
The route searched in the previous step 1416 is stored in the route information database 46 as route information. Then, the information center 40 executes a program (not shown) in response to a distribution request from the mobile terminal of the user including the in-vehicle terminal 20, and newly creates the “automatic generation-movement” schedule and the “automatic generation-stay”. The “possible” schedule is provided to the mobile terminal of the same user.

As described above, according to the fifth embodiment, the movement schedule and the stayable schedule are automatically set, so that the user can move to a certain place for a certain period of time after the end of a certain schedule. You can see if you can stay. Further, when the entered schedule is not established, the fact is notified, so that it is possible to avoid setting an impossible schedule carelessly. Furthermore, even after the "automatic generation-stayable" schedule and the "automatic generation-movement" schedule are set, these are reviewed every time a predetermined time elapses.
It is possible to reach the place of the schedule without delay even under traffic conditions that change from moment to moment, and it is possible to know that the schedule is no longer valid due to changes in traffic conditions. Note that the above steps 1410 to
Reference numeral 1416 is a required time calculating means, and the above steps 1432-
1434 corresponds to the automatic schedule generation means.

(Sixth Embodiment: Method of Automatically Changing Existing Schedule According to Input of New Schedule) Next, a sixth embodiment of the information providing system according to the present invention will be described. The sixth embodiment relates to a method for automatically changing a preset schedule that arrives after the input schedule when the user newly inputs the schedule to the vehicle-mounted terminal 20. Hereinafter, a specific description will be given with reference to FIGS. 15 and 16.

[0138] When the user inputs a new schedule into the vehicle-mounted terminal 20 (including changing the preset schedule), this information is transmitted to the information center 40. As a result, the information center 40 starts the program shown in FIG. 15 from step 1500 and proceeds to step 1502 to input the newly input schedule into the schedule information database 42. The newly input schedule is shown in FIG. 16 as the newly input schedule.

Next, the information center 40 proceeds to step 150.
4, the schedule newly input to the schedule pointer is set in the schedule 1504, and the process proceeds to step 1506. In step 1506, the position ID for the input schedule is associated with the above-described first and second position ID associating methods. Set according to. Setting the position ID means that the position (latitude, longitude) of the movement destination of the same schedule is specified. Subsequently, the information center 40 proceeds to step 1508, and a schedule other than “movement (including stayable)” next to the schedule (newly input schedule at this time) set in the schedule pointer in step 1508. It is determined whether or not the position ID is included in the schedule pointer and whether or not the position ID is included in the schedule set in the schedule pointer in the next step 1510. If the location ID is not included in any of the schedules, the information center 40 proceeds to step 1595.
Go to and end this program.

On the other hand, in any of the above schedules, position I
If D is included, the information center 40 proceeds to step 15
In both steps 08 and 1510, it is determined as “Yes” and the process proceeds to step 1512. In step 1512, the schedule set in the schedule pointer and the “stayable” schedule until the next schedule other than “moving” , “Movement” schedule, and “Route” in the “Movement” schedule are created using the data in the schedule information database 42, the map information database 54, and the traffic information database 55. These creation methods are the same as the creation methods of the other embodiments described above (for example, see the flowchart of FIG. 12).

Next, the information center 40 proceeds to step 151.
In step 4, it is determined whether it is possible to move to a schedule location other than the next "move" by the start time of the schedule other than the "move" next to the schedule set in the schedule pointer. If the information center 40 is movable, the information center 40 displays “Yes” in step 1514.
s ”and proceeds to step 1516, where step 1
In 516, the “stayable” schedule, the “moving” schedule, and the “route” in the “moving” schedule created in step 1512 are stored in each database and the process proceeds to step 1518.

On the other hand, if it is not possible to move to the place of the schedule other than the next "move" by the start time of the schedule other than the "move" next to the schedule set in the schedule pointer, the information center 40 makes a step. In step 1514, it is determined "No" to proceed to step 1520. In step 1520, it is determined whether or not the next schedule other than "movement" is a schedule having a time constraint. The time-limited schedule is a schedule whose start date and time and end date and time cannot be changed.

Then, if the schedule other than the same "movement" is a time-constrained schedule, the information center 40 determines "Yes" in step 1520 and proceeds to step 1522 to schedule the in-vehicle terminal 20. The schedule set in the pointer (in this case, the newly input schedule) is notified that the schedule is not established, and the program is terminated once in step 1595.

On the other hand, at the time of the determination at step 1520, if the schedule other than the next “movement” is not a schedule with a time constraint, the information center 40 determines “No” at step 1520 and proceeds to step 1524. In the same step 1524, the above step 151
The "stayable" schedule, the "moving" schedule, and the "route" in the "moving" schedule created in 2 are stored in each database. Next, in step 1526, the information center 40 changes the start time of the schedule other than the "move" next to the schedule set in the schedule pointer to the time when the margin time tm1 has elapsed from the arrival time of the move schedule. At the same time, the end time of the schedule is delayed (moved) by the time when the start time is delayed. By this operation, the start date and time and the end date and time of the schedule B shown in the schedule table before change in FIG. 16 are automatically changed like the schedule B shown in the schedule table after change in FIG. In such a case, the stayable schedule is not substantially generated.

Thereafter, the information center 40 proceeds to step 15
At 18, the schedule other than "move" next to the schedule currently set in the schedule pointer is set in the schedule pointer, and the above step 1 is performed.
Return to 508. As a result, thereafter, the “moving” schedule and the “stayable” schedule are updated one after another.

As described above, according to the sixth embodiment, when a new schedule is input (including when a preset schedule is changed), the next move and stay of the same schedule are possible. It is determined whether or not it is possible to move in time with respect to other schedules, and when it is possible, the movement schedule, stayable schedule, and route are saved. When the schedule is immovable, if the schedule has no time constraint, the start time and end time of the schedule are automatically changed, and if the schedule has time constraint, Notify the user that the newly input schedule is not established. As a result, the user can add or modify a new schedule while recognizing whether or not the schedule with a time constraint can be surely executed.

(Seventh Embodiment: Method of Automatically Changing Preset Schedule) Next, a seventh embodiment of the information providing system according to the present invention will be described. In the seventh embodiment, the travel schedule and the stayable schedule with respect to the already set schedule (already set schedule) are constantly reviewed, and when the time required for travel (required time) becomes long due to changes in traffic conditions, etc. , A method of automatically changing the start date and time and the end date and time of a preset schedule. Hereinafter, a specific description will be given with reference to FIGS.

The information center 40 is adapted to repeatedly execute the program shown by the flowchart of FIG. 17 at every elapse of a predetermined time. Therefore, at a predetermined timing, the information center 40 starts the process from step 1700 and proceeds to step 1702 to acquire the current date and time. The information center 40 then proceeds to step 170.
In step 1704, the information (state) of the target vehicle is acquired from the vehicle information database 47. The vehicle-mounted terminal 20 executes a program (not shown) to display the vehicle state calculated by the vehicle state calculation means 33 together with its own vehicle ID every time a predetermined time elapses.
The information center 40 stores the vehicle state in the vehicle state database 47 for each vehicle ID. Next, the information center 40 proceeds to step 1706, and in step 1706, the information center 40 determines whether or not the vehicle is currently moving.

Continuing with the explanation that the vehicle is not moving, the information center 40 makes a “No” determination at step 1706 to proceed to step 1708 to obtain the current schedule from the schedule information database 42. In the following step 1710, the current schedule is set in the schedule pointer.

Next, the information center 40 proceeds to step 17
In step 12, it is determined whether or not the position ID is included in the schedule set in the schedule pointer (hereinafter referred to as “schedule of schedule pointer”). If the position ID is not included, the process proceeds to step 1795. Exit this program once.

If the location ID is included in the schedule of the schedule pointer, the information center 40 proceeds to step 1
In step 1714, a schedule other than “move (including stayable)” next to the schedule of the schedule pointer (hereinafter, “Schedule S”
1 ”. ) Does not include the position ID, and if the position ID is not included, the process proceeds to step 1795 to end this program once.

On the other hand, if the position ID is included in the schedule S1, the information center 40 determines "Yes" in step 1714 and proceeds to step 1716. In step 1716, the schedule S1 is changed from the schedule of the schedule pointer. Schedule information database 4 for “stayable” schedules, “moving” schedules, and “routes” in the “moving” schedule up to
2. Created using the data in the map information database 54 and the traffic information database 55. These creating methods are the same as the creating methods of the other embodiments described above.

Next, the information center 40 displays the schedule S.
The process proceeds to step 1718 in which it is determined whether it is possible to arrive at the place of the schedule S1 by the start date and time of 1. In this case, the information center 40 is capable of (1) arriving by the start date and time of the schedule S1, (2) not arriving by the start date and time of the schedule S1, and the schedule S1 has no time constraint. When the schedule is a schedule, and (3) when the schedule S1 cannot arrive by the start date and time and the schedule S1 is a schedule with a time constraint, it is divided into three types.

(1) When it is possible to arrive by the start date and time of the schedule S1 In this case, the information center 40 sends "Y" in step 1718.
es ”, the process proceeds to step 1720, and the“ stayable ”schedule, the“ movable ”schedule, and the“ route ”from the schedule of the schedule pointer to the schedule S1 are respectively stored in the corresponding databases, and in step 1795. Exit this program once.

(2) When the schedule S1 cannot arrive by the start date and time, and the schedule S1 is a schedule with no time constraint. In this case, the information center 40 returns "N" in step 1718.
In step 1722, which determines whether or not there is a time constraint, the process proceeds to step 1724, and in step 1724, the schedule S1 is changed from the schedule of the schedule pointer.
The "stayable" schedule, the "moving" schedule (this "moving" schedule is hereinafter referred to as "schedule S2"), and the "route" are respectively stored in the corresponding databases.

The information center 40 then proceeds to step 172.
6, the start date and time of the schedule S1 is set to a time when the margin time tm1 has elapsed from the arrival time of the schedule S2 in the same step 1726, and the end date and time of the schedule S1 is moved by the time when the start date and time is changed. To do. After that, the information center 40 proceeds to step 1728, sets the schedule other than the next "move" (in this case, schedule S1) to the schedule pointer in step 1728, and returns to step 1714. As a result, the validity of the schedule after the current date and time is confirmed.

(3) In the case where the schedule S1 cannot arrive by the start date and time and the schedule S1 is a schedule with a time constraint In this case, the information center 40 returns "N" in step 1718.
No ”, and in step 1722, the determination is“ Yes ”and the process proceeds to step 1730. In step 1730, the in-vehicle terminal 20 is notified that the schedule of the schedule pointer is not established, and in step 1795, the program ends once. To do.

Next, the case where the vehicle is moving will be described. When the information center 40 proceeds to step 1706, it determines “Yes” in step 1706, proceeds to step 1732, and proceeds to step 1732. "Move (including stayable)" immediately before the schedule pointer
Other schedules are set, and in step 1734, the current location of the vehicle is set as the departure location. Next, information center 4
If 0, the process proceeds to step 1736, and the position ID is included in the schedules (hereinafter, referred to as “schedule S3”) other than “move (including stayable)” next to the schedule set in the schedule pointer in step 1736. Is determined. And schedule S3
If the location ID is not included in the information, the information center 40 proceeds to step 1795 and ends the present program.

On the other hand, when the position ID is included in the schedule S3, the information center 40 proceeds to step 1738, and in step 1738, the schedule S3 starts from the place of departure.
A "movement" schedule and a "route" to a position determined by the position ID of 3 are created. Next, information center 40
Advances to step 1740, and it is determined whether it is possible to arrive at the place of the schedule S3 by the start date and time of the schedule S3. Even in this case, the information center 40
(4) if the arrival is possible by the start date and time of the schedule S3, (5) if the arrival is not possible by the start date and time of the schedule S3, and the schedule S3 is a schedule with no time constraint, and (6) If the schedule S3 cannot arrive by the start date and time and the schedule S3 has a time constraint, it is divided into three types.

(4) When it is possible to arrive by the start date and time of the schedule S3 In this case, the information center 40 sends "Y" at step 1740.
es ", the process proceeds to step 1795 to end this program once.

(5) When the schedule S3 cannot arrive by the start date and time, and the schedule S3 is a schedule with no time constraint In this case, the information center 40 returns "N" in step 1740.
In step 1742, which determines whether or not there is a time constraint, the process proceeds to step 1744, and in step 1744, the schedule S3 is changed from the schedule of the schedule pointer.
The "stayable" schedule, the "moving" schedule (this "moving" schedule is hereinafter referred to as "schedule S4"), and the "route" are respectively stored in the corresponding databases.

The information center 40 then proceeds to step 174.
6, the start date and time of the schedule S3 is set to the time when the margin time tm1 has elapsed from the arrival time of the schedule S4 in the same step 1746, and the end date and time of the schedule S3 is moved by the time when the start date and time is changed. To do. After that, the information center 40 proceeds to step 1748 to set a schedule other than "move" next to the current schedule pointer in the schedule pointer, and thereafter proceeds to step 1714 and thereafter to examine the feasibility of the subsequent schedule.

(6) In the case where the schedule S3 cannot arrive by the start date and time and the schedule S3 is a schedule with a time constraint In this case, the information center 40 determines "N" in step 1740.
No ”, and in step 1742, it is determined“ Yes ”and the process proceeds to step 1730. In step 1730, the in-vehicle terminal 20 is notified that the schedule of the schedule pointer is not established, and in step 1795, the program ends once. To do.

18 and 19 schematically show an example of changing the schedule according to the seventh embodiment. FIG.
Shows the case where the travel schedule between schedule A and schedule B changes due to changes in traffic conditions. In this case, since the schedule B is a schedule with no time constraint, its start date and time and end date and time are automatically changed. In FIG. 19, as a result of the movement schedule between Schedule A and Schedule B changing due to changes in traffic conditions, Schedule B and Schedule C without time constraints have been moved, but Schedule D with time constraints must also move. This shows a case where the schedule D must be reached (that is, the schedule D start date and time cannot reach the schedule D location). In this case, the information center 40
In-vehicle terminal 20 indicates that Schedule C is no longer established
To notify. As described above, according to the seventh embodiment, the schedule is automatically changed. Note that FIG. 20 shows a specific example of the schedule thus generated.

(Eighth Embodiment: Automatic Generation Method of Past Schedule Based on Movement Result) Next, an eighth embodiment of the information providing system according to the present invention will be described. This 8th
In the embodiment, the information center 40 stores the past information based on vehicle information (current position, traveling direction, and traveling speed) from the vehicle-mounted terminal 20 that functions as a navigation device and information indicating whether the engine has started or turned off. This is a method of automatically generating and saving the schedule (history) of. Figure 21
Shows an example for explaining the outline of the schedule automatically generated in this way, and as shown in the figure, the detailed schedule for the part that was “travel” before the automatic generation is shown. Is automatically generated.

The operation of the eighth embodiment will be described in detail below. The in-vehicle terminal 20 starts the processing of the program shown in FIG. 22 from step 2200 when the engine of the vehicle is started (step 2200). In step 2202, the current time is acquired. Next, the in-vehicle terminal 20 proceeds to step 2204, and in step 2204, the information center 4
Send information indicating that the engine has started to 0,
In the following step 2206, time counting by the timer T1 is started.

Next, the in-vehicle terminal 20 makes a step 2208.
To step 221.
At 0, it is determined whether the engine is off (the engine is stopped). Continuing with the explanation that the engine is still operating, the in-vehicle terminal 20 determines in step 2212.
Then, in step 2212, it is determined whether the timer T1 has counted a predetermined time. In this case, since the timer T1 has just started counting time, it has not finished counting the predetermined time. Therefore, the in-vehicle terminal 20 proceeds to step 2212.
Then, it is determined to be “No” and the process returns to step 2208.

After that, when the predetermined time has elapsed without the engine being turned off and the timer T1 completes the time measurement of the predetermined time, the in-vehicle terminal proceeds to step 2212,
In step 2212, the determination is “Yes” and the process proceeds to step 2214. In step 2214, the vehicle information including the current position of the own vehicle, the traveling direction, and the traveling speed is acquired. Next, the vehicle-mounted terminal 20 proceeds to step 2216, transmits the vehicle information to the information center 40 in step 2216, and returns to step 2206. In this way, the vehicle-mounted terminal 20 transmits the vehicle information to the information center 40 each time a predetermined time elapses.

Thereafter, the in-vehicle terminal 20 makes a step 2206.
Since steps 2216 to 2216 are repeatedly executed, when the engine is turned off (stopped), it is determined to be “Yes” in step 2210, the process proceeds to step 2218, and information indicating that the engine is turned off is sent to the information center 40. Then, the program is terminated at step 2295.

On the other hand, the information center 40 repeatedly executes the program shown in FIG. 23 every time a predetermined time elapses. First, the case where the engine is started will be described. The information center 40 starts processing from step 2300 at a predetermined timing, and then step 2302.
At step 2304, a process for receiving a signal from the vehicle-mounted terminal 20 is performed, and it is determined at step 2304 whether or not information is received. In this case, since the engine has just been started, the vehicle-mounted terminal 20 transmits a signal indicating that. Therefore, the information center 40 determines “Yes” in step 2304 and proceeds to step 2306 to determine whether the received signal is a notification that the engine has been started or turned off. In this case, since the received signal is a signal indicating that the engine has started, the information center 40 sends “Y” in step 2306.
es ”, the process proceeds to step 2308, and the state of the recognized engine is updated. That is, in this case, it is recognized that the engine is operating.

Next, the information center 40 proceeds to step 231.
In step 0, it is determined whether the received signal is a signal notifying the start of the engine. In this case, since the received signal is a signal for notifying the start of the engine, the information center 40 sends “Yes” at step 2310.
s ”, the running state after engine start is set to“ not running ”in step 2312, and the process proceeds to step 2395 to end the present program tentatively.

After that, the information center 40 performs steps 2300, 2302, and step 23 every time a predetermined time elapses.
The processing of 04 is repeatedly executed. Therefore, the in-vehicle terminal 20
When the vehicle information is transmitted by the processing in step 2216, the information center 40 returns “Yes” in step 2304.
Then, the process proceeds to step 2306, and the signal received this time is not a signal for notifying the start or off of the engine. Therefore, it is determined “No” at step 2306, the process proceeds to step 2314, and at step 2314. The received vehicle information is recorded in the vehicle information database 47.

The information center 40 then proceeds to step 231.
6, the process proceeds to step 2316, and it is determined whether or not the running state after engine start is "not running". In this case, since the traveling state after the engine is started is set to “not traveling” in step 2312, the information center 40 determines “Yes” in step 2316 and determines in step 2
Proceeding to 318, the running state after the engine is started is changed to "running" in the same step 2318.

The information center 40 then proceeds to step 232.
At 0, the current date and time is acquired, at step 2322, the latest “waiting for automatic generation-stop” schedule is acquired, and at step 2324, it is determined whether or not there is a “waiting for automatic schedule-stop” schedule. To do. In this case, since there is no “automatic generation-stop” schedule for waiting for schedule end, the information center 40 makes a “No” determination at step 2324 to proceed to step 2326, and at step 2326 waits for “automatic generation” at the end. -Move "Create and save schedules.

Details of the process of creating / saving the "automatic generation-migration" schedule are shown in FIG. To be more specific with reference to FIG. 24, the information center 40 proceeds from step 2400 to step 2402 to obtain the current date and time, and proceeds to step 2404 to check for a schedule other than the preceding “movable or stayable”. The position information (latitude, longitude) is acquired based on the position ID, and the process proceeds to step 2406 to search for the place name based on the position information.

The information center 40 then proceeds to step 240.
8, the schedule ID is set in step 2408, the notification status is not notified, the start date and time is the current date and time, the name is the location name searched in step 2406, the content is moving, and the type is “automatic”. "Generate-Move", the start point ID is set to the position ID of the immediately preceding schedule, and the moving means is set to "car" to create an "automatic-Move" schedule. Then, in step 2410, the information center 40 saves the “automatic generation-migration” schedule created in this way as an end waiting schedule, and in step 24
23, the program proceeds to step 2395 in FIG. 23, and this program is temporarily terminated.

After that, the information center 40 operates the in-vehicle terminal 20.
Step 2 is to check whether the vehicle information transmitted from
Since monitoring is performed in 300 to 2304, when vehicle information is received, it is determined to be “Yes” in step 2304 and “No” in step 2306, and step 2314 is performed.
The vehicle information is recorded at and the process proceeds to step 2316. In this case, since the running state after the engine start is set to running in step 2318, the information center 40
Determines “No” in step 2316 and determines in step 2
In step 328, the traveling locus is stored based on the received vehicle information in step 2328, and the program is terminated once in step 2395. Thereafter, this processing is repeated and the traveling locus of the vehicle is stored.

In this state, when the driver turns off the engine of the vehicle, this information is transferred from the vehicle-mounted terminal 20 to the information center 4.
Information center 40 is sent to step 230.
In step 2306 subsequent to 0, 2302, and 2304, it is determined to be “Yes”, the process proceeds to step 2308, and in step 2308, the engine state is updated (that is, the engine is recognized to be off). Next, the information center 40 makes a “No” determination at step 2310 to proceed to step 23.
At 40, the running state after engine start is set to "not running", and at next step 2342, the current date and time is acquired.

The information center 40 then proceeds to step 234.
In step 2344, the latest “waiting for automatic generation-movement” schedule is acquired, and in the following step 2346, it is determined whether there is a schedule for waiting “automatic generation-migration” schedule. in this case,
Waiting for end of schedule Since the “automatic generation-movement” schedule is generated in step 2326, the information center 40 determines “Yes” in step 2346 and proceeds to step 2348. Generation-Movement ”Schedule setting / saving processing is performed.

FIG. 25 shows the details of the setting / saving process of this end waiting “automatic generation-movement” schedule.
To be more specific with reference to FIG. 25, the information center 40
Advances from step 2500 to step 2502 to acquire the current date and time, advances to step 2504 to acquire the latest vehicle position from the vehicle information database 47, and then
In step 2506, the place name is searched based on the vehicle position information.

Next, the information center 40 proceeds to step 250.
Then, the process of creating a route is performed based on the traveling locus stored in the vehicle information database 47 and the data in the map information database 54, and the route created in step 2510 is assigned a route ID. Then, it is stored in the route information database 46. Next, the information center 40 proceeds to step 2512, where the current date and time is the “end date and time” in step 2512, the “name” already entered in the “name” column, the arrow and the location searched in step 2506. A name is added to the name, a position ID is newly given (set), the set position ID is set as an "end point ID", and the route ID of step 2510 is set as a "route ID".
Complete the "Automatic Generation-Movement" schedule. afterwards,
The information center 40 saves the “automatic generation-movement” schedule completed in step 2514 in the schedule information database 42, and via step 2595, FIG.
Return to step 2350 of 3.

Next, the information center 40 proceeds to step 235.
At 0, the process of creating and saving the schedule of “automatic generation-stop” waiting for completion is performed. The details of the process of creating and saving the "automatic generation-stop" schedule are shown in FIG. More specifically, referring to FIG. 26, the information center 40 proceeds from step 2600 to step 2602 to acquire the current date and time, and proceeds to step 2604 to see if there is a previous “automatic generation-movement” schedule. Determine whether or not.

In this case, since the previous "automatic generation-movement" schedule exists by the processing of the previous step 2348, the information center 40 makes a "Yes" determination at step 2604 to proceed to step 2606. At step 2606, position information is acquired from the end point ID of the immediately preceding “automatic generation-movement” schedule. Next, the information center 40 proceeds to step 2608, and the step 260
8, the location name, address, based on the acquired location information
And retrieve the phone number.

Subsequently, the information center 40 proceeds to step 261.
0, the schedule ID is set, the notification status is not notified, the start date and time is the current date and time, the name is the place name searched in step 2608, the content is parked, the type is automatically generated-parking, address and telephone. An "automatic generation-stop" schedule is created by using the address, telephone number, place name, and location ID searched for the number and facility name in step 2608 as the end point ID of the immediately preceding "automatic generation-movement" schedule, Saved in the schedule information database 42.

Next, the information center proceeds to step 2612, and in step 2612, the position ID is the end point ID of the previous automatic generation-movement schedule, the name is the place name retrieved in step 2608, and the latitude is the vehicle position. Position information is created by using the latitude and longitude of the vehicle position as the longitude of the vehicle position and the schedule ID as the schedule ID set in step 2610, saves the position information in the position information database 45, and, via step 2695, step 2 in FIG.
Proceed to 352. The information center 40 then proceeds to step 23.
At 52, the traveling locus is erased, and the program proceeds to step 2395 to end the program of FIG. 23 once. By the above, the "automatic generation-movement" schedule is completed, and a new "automatic generation-stop" schedule waiting for completion is generated together with the position information indicating the parking position of the vehicle.

After that, since the engine is turned off, the vehicle-mounted terminal 20 does not send any information. Therefore, the information center 40 only executes steps 2300 to 2304 repeatedly.

After that, when the engine is started again, the vehicle-mounted terminal 20 notifies the information center 40 that the engine has started. Therefore, the information center 40 determines “Yes” in steps 2304 and 2306, proceeds to step 2308, updates the engine state in step 2308, proceeds to steps 2310 and 2312, and after engine start. The running state is "not run". Further, when the information center 40 next receives the vehicle information, the information center 40 passes through steps 2300 to 2306 and steps 2314 to 2322 to step 232.
Up to 4. In this case, since the “automatic generation-stop” schedule is created in the previous step 2350 and is saved in the schedule end waiting state, the information center 40 determines “Yes” in step 2324 and determines in step 23.
In step 54, the current date and time is set as the end date and time of this “waiting for completion” “automatic generation-stop” schedule, and the schedule information database 42 stores it. This completes the "automatic generation-stop" schedule. And step 2
After creating and saving a new "automatic generation-move" schedule in 326, the program is terminated once in step 2395.

As described above, according to the eighth embodiment, since the movement schedule and the stop schedule are automatically generated based on the traveling result of the vehicle, the user omits the work of inputting them based on his own memory. be able to.

(Ninth Embodiment: Participant Schedule Automatic Correction Method) Next, a ninth embodiment of the information providing system according to the present invention.
An embodiment will be described. The ninth embodiment determines whether or not the user can arrive at the place of the next schedule by the start date and time of the next schedule, and if it is predicted that the user cannot arrive at the place of the next schedule, the schedule information of the visit partner or the participant is obtained. The present invention relates to a method for automatically correcting a schedule in which a free time of a visit partner or a participant is searched, the schedule is changed to the free time, and the result of the change is notified to the visit partner or the participant.

The operation of the ninth embodiment will be described in detail below. The information center 40 repeatedly executes the program shown in FIG. 27 every time a predetermined time elapses. Therefore, at a predetermined timing, the information center 4
0 starts the process from step 2700 and then starts step 27
02, the current date and time is acquired in step 2702. Next, the information center 40 acquires the current vehicle information from the vehicle information database 47 in step 2704, and then, in steps 2706 to 2724, determines the departure point and the destination for predicting the route search and arrival date and time. Make settings. In the following, description will be made for different cases.

In the case where the information center 40 is currently moving In this case, the information center 40 makes a “Yes” determination at step 2706 to determine whether or not the vehicle is currently moving, proceeds to step 2708, and proceeds to the next step 2708. The schedule other than “Move (including stayable)” is acquired, the current location is set as the departure point in the following step 2710, and the position searched from the position ID of the next schedule other than “Move” is set as the destination. To do.

When not currently moving (a) When the current schedule is not the moving schedule In this case, the information center 40 returns "N" in step 2706.
"o" and proceeds to step 2712, where step 2
At 712, the current schedule is acquired from the schedule information database 42. Next, information center 40
Determines in step 2714 whether the current schedule is a “moving” schedule, determines “No”, and proceeds to step 2716. In step 2716, schedule information other than the next “moving” schedule is set. It is acquired from the database 42. And the information center 40
At step 2718, the position retrieved from the position ID of the current schedule is set as the departure point, and the position retrieved from the position ID of the schedule other than the next movement is set as the destination.

(B) When the current schedule is a movement schedule In this case, the information center 40 returns "Y" at step 2714.
es ”, the process proceeds to step 2720, the schedule other than the previous“ movement ”is acquired in step 2720, and the process proceeds to step 2722 to acquire the next schedule other than“ movement ”. Then, the information center 40 proceeds to step 2724, sets the position retrieved from the position ID of the schedule other than the previous “movement” in step 2724 as the departure point, and sets the position of the next schedule other than “movement”. The position retrieved from the position ID is set as the destination.

When the starting point and the destination are determined as described above, the information center proceeds to step 2726, and at the step 2726, the data in the map information database 54 and the traffic information database 55 is used to change the destination from the destination. Search for a route to the destination and predict the date and time of arrival at the destination by the route. Then, the information center 40 proceeds to step 2728 and determines whether or not the estimated arrival date and time is later than the start date and time of the schedule other than the next “movement” in step 2728.

At this time, if the estimated arrival date and time is earlier than the start date and time of the schedule other than the next "movement", it is not necessary to automatically adjust the schedule, and therefore the information center 4
0 immediately advances to step 2795 to end this program once. On the other hand, if the estimated arrival date and time is later than the start date and time of the schedule other than the next “movement”, the schedule needs to be changed, and therefore the information center 40 determines “Yes” in step 2728 and determines “Yes” in step 273.
In step 2730, the participant schedule is automatically adjusted and notified. Details of this process are shown in FIG.
8 is shown.

That is, the information center 40 proceeds to step 2800.
Processing is started, the process proceeds to step 2802, the start date and time of the schedule other than the next "movement" is set to date and time t1, the end date and time of the schedule is set to date and time t2, and the difference between date and time t2 and date and time t1 is set to time t3. To do. Next, the information center 40 proceeds to step 2804 and sets the arrival date and time predicted at step 2726 to date and time t4 and the same date and time t4.
The date and time when the time t3 has elapsed is set to the date and time t5, the schedule information of the participants (including oneself) of the schedule other than the next "movement" is searched for in step 2806, and all the participants proceed to step 2808. It is determined whether a schedule has not been set (whether it has not been set) between the times t4 and t5.

At this time, if all the participants have not set the schedule between the dates t4 and t5, the information center 40 makes a "Yes" determination at step 2808 to proceed to step 2810 and step 2810. At, the schedule set between the participants' dates and times t1 and t2 is acquired, and the start date and time of this schedule is stored as date and time t4 and the end date and time is stored as date and time t5. Next, the information center 40 obtains the contact information from the personal information of the participants at step 2812, and at step 2814 the next "move".
Notifying that the start date and time and the end date and time of schedules other than are changed, and terminates this program in step 2895.

On the other hand, at the time of execution of step 2808, if any one of the participants has set the schedule during the time t4 to t5, the information center 40 causes the information center 40 to execute the step 2
In step 808, the determination is “No”, and the process proceeds to step 2816.
It is determined whether a schedule can be set in 4 to t5. This determination is, for example, whether or not the schedule set for the date and time t4 to t5 of any one of the participants is a part of the schedule set between the date and time t1 and t2, and / or the stay is possible. This is done by determining whether it is a schedule. Then, if the schedule can be set for all the participants during the time t4 to t5, the information center 40 returns “Yes” in step 2816.
Then, the process proceeds to step 2810 described above.

When the determination in step 2816 is "No", the information center 40 proceeds to step 2818, and in step 2818, the time t3 is added to the time t3 in the schedule of all the participants today. Time (t
It is determined whether or not there is a common time zone (hereinafter referred to as “vacant time”) in which no schedule is incorporated over a time of 3 + tm) or more.

If there is such a free time, the information center 40 returns "Yes" in step 2818.
s ”and proceeds to step 2820, where step 2
At 820, the date and time t1 to t from the participant schedule information
The schedule set to 2 is acquired, the start date and time of the acquired schedule is set to the date and time obtained by adding time tm to the start date and time of the free time, and the end date and time of the acquired schedule is set to the set start date and time. It is set to a date and time after the time t3 has elapsed. After that, the information center 40 executes steps 2812 and 2814 to notify the participants that the start date and time of the schedule other than the "movement" has been changed, and ends the program once in step 2895.

If there is no such free time, the information center 40 returns "N" in step 2818.
"o" and proceeds to step 2822, where step 2
At step 822, a process of notifying the person that automatic adjustment of the schedule other than the next "movement" is impossible is performed, and at step 2895, the present program ends. It should be noted that the notification to the person in question may be made to the in-vehicle terminal 20 or to the cell phone of the person in question. Then, the information center 40 proceeds to step 2795 of FIG. 27 via step 2895 and once ends this program.

As described above, according to the ninth embodiment, when it is predicted that the place of the same schedule cannot be reached by the start time of the certain schedule due to changes in traffic conditions and the like, the participants of the same schedule. The schedule is automatically corrected with reference to the schedule and the result of the correction is notified to the participants. Therefore, the user
There is no need to modify the schedule and contact the participants regarding the modification results.

As described above, according to each embodiment of the present invention, appropriate schedule management can be performed and effective information can be provided to the user.
