When receiving the vehicle information transmitted from each vehicle (terminal device 1), the microcomputer 12 stores the received vehicle information in the database 14 in association with the ID code. Further, when there is a vehicle information transmission request from each vehicle (terminal device 1), the microcomputer 12 can transmit the vehicle information to the vehicle in response to the transmission request. Further, in the terminal device 1, a user (a vehicle driver or the like) is displayed through a screen displayed on the display panel 5a.
Can make various settings (for example, destination and key code settings).

Next, the processing operation of the microcomputer 2 in the terminal device 1 according to the embodiment (1) will be described based on the flowcharts shown in FIGS. 3A and 3B. First, information on the destination and key code set by the user through the screen displayed on the display panel 5a is stored in the memory m1 in the microcomputer 2 (step S1), and then the information is stored in the EEPROM 6 as the information. A signal with the ID code (see FIG. 4) is transmitted to the location information providing device 11 installed in the management organization via the mobile communication means 7 (step S2), and then the timers t ₁ , t Start with _{2 set} to 0 (step S3). As will be described in detail later, when the position information providing device 11 receives these information from the terminal device 1 mounted on each vehicle, the information is associated with the ID code as shown in FIG. It is stored in the database 14.

Then, the timer t ₁ is 'determines whether a higher (step S4), and the timer t ₁ is a predetermined time period t _1' predetermined period t ₁ if it is determined to be equal to or greater than, then GPS receiver The position information of the host vehicle M is received from the means 3 (step S5), and the received position information and information regarding the reception time of the position information are stored in the memory m2 in the microcomputer 2 (step S6). A signal (see FIG. 5) with the ID code stored in the EEPROM 6 added to these information is transmitted to the position information providing device 11 via the mobile communication means 7 (step S7), and then the timer t ₁ is set. Set to 0 (step S8), and proceed to step S9. On the other hand, if it is determined that the timer t ₁ is not equal to or longer than the predetermined period t ₁ ′, the operation of steps S5 to S8 is skipped and the process proceeds to step S9.

As shown in FIG. 2, when the location information providing device 11 receives the location information and the reception time information from the terminal device 1 mounted on each vehicle, as in the case of receiving the information about the destination and the keyword. In addition, the information is stored in the database 14 in association with the ID code.

Then, the timer t ₂ is 'determines whether a higher (step S9), and the timer t ₂ is a predetermined time period t _2' predetermined period t ₂ if it is determined that it is more, then, the position information The information providing device 11 is requested to transmit information on the other vehicle P and map information around the position of the host vehicle M via the mobile communication means 7 (step S10). For example, a signal (see FIG. 6) with the ID code stored in the EEPROM 6 added to the information transmission request code is transmitted.

As will be described in detail later, when the position information providing device 11 receives the signal as shown in FIG. 6, the information on the other vehicle P and the map information around the position of the vehicle that has transmitted the information transmission request code are obtained. The data is transmitted to the terminal device 1. For example, when the ID code set in the vehicle (terminal device 1) that requests transmission of other vehicle information is “001”, the database 1
4, vehicle information stored in association with the ID codes “002”, “003”,... Is transmitted to the terminal device 1.

Next, when the information of the other vehicle P and the map information transmitted from the position information providing device 11 are received (step S11), the received information on the other vehicle P is associated with the ID code and stored in the memory in the microcomputer 2. In addition to storing in m3 (step S12), the received map information around the position of the host vehicle M is stored in the memory m4 in the microcomputer 2 (step S13). FIG. 7 shows an example of a state in which the information on the other vehicle P is stored in the memory m3.

Next, based on the position information of the host vehicle M stored in the memory m2 and the map information around the position of the host vehicle M stored in the memory m4, as shown in FIG. Is displayed on the display panel 5a (step S14), then the counter n is set to 1 (step S15), and the position information of the nth other vehicle Pn stored in the memory m3 is new. Whether or not, that is, a predetermined time from the update time in the position information of the other vehicle Pn (
For example, it is determined whether it is within 10 minutes (step S16).

If it is determined that the position information of the other vehicle Pn is new, then the own vehicle M is stored based on the position information of the own vehicle M stored in the memory m2 and the position information of the other vehicle Pn stored in the memory m3. A distance S between the vehicle M and the other vehicle Pn is obtained (step S17), and the obtained distance S is a predetermined distance S.
It is determined whether or not the following is true (step S18).

If it is determined that the distance S is equal to or less than the predetermined distance S ′, then the key code information set in the host vehicle M stored in the memory m1 and the other vehicle Pn stored in the memory m3 are stored. Based on the set key code information, these key codes are collated to determine whether there are two or more matching key codes (step S19).

If it is determined that there are two or more matching key codes, then the position of the other vehicle Pn is within a displayable range on the map displayed on the display panel 5a based on the position information of the other vehicle Pn. If it is determined whether it is within the displayable range (step S20), for example, as shown in FIG. 9, the positions of the other vehicles P1, P2 are displayed in red on the map ( Then, the process proceeds to step S27. On the other hand, if it is determined that it is not within the displayable range, for example, as shown in FIG. 9, the direction in which the other vehicle P3 exists is displayed in red on the map (step S22), and then the process proceeds to step S27.

If it is determined in step S19 that two or more matching key codes do not exist, it is next determined whether or not there is one matching key code (step S23). Then, based on the position information of the other vehicle Pn,
It is determined whether or not the position of the other vehicle Pn is within a displayable range on the map displayed on the display panel 5a (step S24). 9
As shown in FIG. 5, the position of the other vehicle P4 is displayed in yellow on the map (step S25), and then the process proceeds to step S27. On the other hand, if it is determined that it is not within the displayable range, for example, as shown in FIG. 9, the direction in which the other vehicle P5 exists is displayed in yellow on the map (step S26).
Thereafter, the process proceeds to step S27.

Further, in step S16, it is determined that the position information of the other vehicle Pn is not new, or in step S18, it is determined that the distance S is not equal to or less than the predetermined distance S ′, or in step S2.
3, if it is determined that there is no matching key code, the display importance of the position of the other vehicle Pn is regarded as low, and the process directly proceeds to step S27.

In step S27, 1 is added to the counter n, and then it is determined whether or not the information on the other vehicle Pn is stored in the memory m3 (step S28), and the information on the other vehicle Pn is stored in the memory m3. If it is determined that there is, the process returns to step S16. If determined that the memory m3 of another vehicle Pn information is not stored, the timer t ₂ is set to 0 (step S29), then returns to In step S4 (Fig. 3A).

Next, the processing operation performed by the microcomputer 12 in the position information providing apparatus 11 according to the embodiment (1) will be described based on the flowchart shown in FIG. First, it is determined whether or not a signal transmitted from the outside has been received via the communication means 15 (step S31). If it is determined that a signal from the outside has been received, then the vehicle is added to the received signal. It is determined whether or not vehicle information transmitted from (terminal device 1) is included, that is, whether or not the signal is a signal as shown in FIGS. 4 and 5 (step S32). On the other hand, if it is determined in step S31 that a signal transmitted from the outside has not been received, the processing operation ends.

If it is determined in step S32 that the received signal includes the vehicle information, the vehicle information is stored in the database 14 in association with the ID code as shown in FIG. 2 (step S33). . On the other hand, if it is determined that the vehicle information is not included in the received signal, next, whether or not an information transmission request code transmitted from the vehicle (terminal device 1) is included in the received signal. That is, it is determined whether or not the signal is a signal as shown in FIG. 6 (step S34).

If it is determined that an information transmission request code is included in the received signal (that is, the vehicle T that has transmitted the signal requests transmission of information of another vehicle), then the received signal The vehicle information other than the vehicle T is read from the database 14 based on the ID code included in (step S35). Next, the position information of the vehicle T is stored in the database based on the ID code included in the received signal. 14 (step S36), based on the read position information, map information around the position of the vehicle T is read from the map information storage means 13 (step S37), and then the vehicle information read in step S35 and step S37.
The map information read out in (5) is transmitted to the vehicle T (terminal device 1) via the communication means 15 (step S38). On the other hand, if it is determined in step S34 that the received signal does not contain the information transmission request code, the processing operation is terminated as it is.

Set to 0 (step S48), and proceed to step S49. On the other hand, if it is determined that the timer t ₁ is not equal to or longer than the predetermined period t ₁ ′, the operation of steps S45 to S48 is skipped and the process proceeds to step S49.

As in the case of receiving the destination information, the location information providing device 11A receives the location information and the reception time information from the terminal device 1A mounted on each vehicle, as shown in FIG. The information is stored in the database 14A in association with the code.

Then, the timer t ₂ is 'determines whether a higher (step S49), the timer t ₂ is a predetermined time period t _2' predetermined period t ₂ if it is determined that it is more, then, the position information 11 A of equivalence | providing apparatuses are requested | required of the transmission of the information of the other vehicle P and the map information around the position of the own vehicle M via the mobile body communication means 7 (step S50).

The own vehicle M does not belong to a plurality of groups, that is, the group code (2) is “0”.
If it is determined that it is “0”, then the other vehicle P stored in the nth memory in the memory m3.
It is determined whether or not the position information of n is new, that is, whether or not it is within a predetermined time (for example, 10 minutes) from the update time in the position information of the other vehicle Pn (step S57).

If it is determined that the position information of the other vehicle Pn is new, then the own vehicle M is stored based on the position information of the own vehicle M stored in the memory m2 and the position information of the other vehicle Pn stored in the memory m3. A distance S between the vehicle M and the other vehicle Pn is obtained (step S58), and the obtained distance S is a predetermined distance S.
It is determined whether or not it is below (step S59).

Is displayed in blue on the map (step S62), and then the process proceeds to step S64. On the other hand, if it is determined that it is not within the displayable range, the direction in which the other vehicle Pn exists is displayed in blue on the map (step S63), and then the process proceeds to step S64.

In step S57, it is determined that the position information of the other vehicle Pn is not new, or in step S59, it is determined that the distance S is not equal to or less than the predetermined distance S ′, or in step S6.
If it is determined at 0 that the groups to which they belong do not match, the display importance of the position of the other vehicle Pn is regarded as low, and the process directly proceeds to step S64.

If it is determined, the process returns to step S57. If determined that the memory m3 of another vehicle Pn information is not stored, the timer t ₂ is set to 0 (step S66), then returns the step S44 (FIG. 12A).

On the other hand, if it is determined in step S56 that the host vehicle M belongs to a plurality of groups, that is, the group code (2) is not “00”, the nth memory is next stored in the memory m3.
It is determined whether or not the position information of the other vehicle Pn stored next is new, that is, whether or not it is within a predetermined time (for example, 10 minutes) from the update time in the position information of the other vehicle Pn (
Step S67).

If it is determined that the position information of the other vehicle Pn is new, then the own vehicle M is stored based on the position information of the own vehicle M stored in the memory m2 and the position information of the other vehicle Pn stored in the memory m3. A distance S between the vehicle M and the other vehicle Pn is obtained (step S68), and the obtained distance S is a predetermined distance S.
It is determined whether or not the following is true (step S69).

If it is determined that the distance S is equal to or less than the predetermined distance S ′, then information on the group code (1) of the group to which the host vehicle M belongs and the group of the group to which the other vehicle Pn stored in the memory m3 belongs. Based on the information on the codes (1) and (2), it is determined whether or not the groups to which they belong match (step S70).

If it is determined that the groups to which the groups belong are the same, next, information on the group code (2) of the group to which the host vehicle M belongs, and the group code (1) of the group to which the other vehicle Pn belongs stored in the memory m3 ( Based on the information regarding 2), it is determined whether or not the two groups to which both belong are the same (step S71).

If it is determined that the two groups belong to each other, then the position of the other vehicle Pn is within the displayable range on the map displayed on the display panel 5a based on the position information of the other vehicle Pn. (Step S72), and if it is determined that it is within the displayable range, the position of the other vehicle Pn is displayed in red on the map (step S73), and then the process proceeds to step S82. On the other hand, if it is determined that it is not within the displayable range, the direction in which the other vehicle Pn exists is displayed in red on the map (step S74), and then the process proceeds to step S82.

In step S71, if it is determined that only one group belongs, that is, only the group corresponding to the group code (1) matches, the other vehicle P
Based on the position information of n, it is determined whether or not the position of the other vehicle Pn is within a displayable range on the map displayed on the display panel 5a (step S75), and is within the displayable range. If determined, the position of the other vehicle Pn is displayed in blue on the map (step S76), and then the process proceeds to step S82. On the other hand, if it is determined that it is not within the displayable range, the direction in which the other vehicle Pn exists is displayed in blue on the map (step S77), and then the process proceeds to step S82.

If it is determined in step S70 that the other vehicle Pn does not belong to the group corresponding to the group code (1), then the group code (2
) And the information related to the group codes (1) and (2) of the group to which the other vehicle Pn belongs stored in the memory m3, it is determined whether or not the groups to which they belong match (step S78). ).

If it is determined that the group to which the group belongs is matched, that is, only the group corresponding to the group code (2) is matched, then the position of the other vehicle Pn is displayed on the display panel 5a based on the position information of the other vehicle Pn. It is determined whether or not it is within the displayable range on the map (step S79). If it is determined that it is within the displayable range, the position of the other vehicle Pn is displayed in yellow on the map (step S79). After that, the process proceeds to step S82. On the other hand, if it is determined that it is not within the displayable range, the direction in which the other vehicle Pn exists is displayed in yellow on the map (step S8).

In step S67, it is determined that the position information of the other vehicle Pn is not new, or in step S69, it is determined that the distance S is not equal to or less than the predetermined distance S ′, or in step S7.
If it is determined in step 8 that the groups to which the groups belong does not match, it is considered that the display importance of the position of the other vehicle Pn is low, and the process directly proceeds to step S82.

If it is determined, the process returns to step S67. If determined that the memory m3 of another vehicle Pn information is not stored, the timer t ₂ is set to 0 (step S84), then returns the step S44 (FIG. 12A).

According to the information providing system including 1 and 11A, the notification importance of the position of the other vehicle is obtained based on the other vehicle information, and the other vehicle's position is calculated based on the obtained notification importance. Differentiate location announcements.

As a result, it is possible to prevent the map from being filled with marks indicating the positions of other vehicles, so that it is possible to prevent the position of other vehicles from being difficult to check or the map itself from becoming difficult to see. . Moreover, since only the information (for example, the position of the vehicle driven by the fellow) can be displayed on the map, the occupant can surely confirm only what is necessary.

In the terminal device according to the above embodiment (1) or (2), the notification importance of other vehicles is determined based on the distance S from the own vehicle M, but in another embodiment, the own vehicle You may make it judge the notification importance of another vehicle based on the distance with the destination of M.

This map may be displayed, and other vehicles existing in the vicinity of the other vehicle may be preferentially notified.

In this case, it is necessary to have the map information around the destination transmitted from the location information providing devices 11 and 11A installed in the management organization. However, if the host vehicle M is equipped with a map information storage means storing map information and the terminal device is able to use the map information stored in the map information storage means, the map information is obtained from the management organization. There is no need to have it sent.

Further, in the terminal device according to yet another embodiment, the other vehicle is not displayed on the map, for example, as shown in FIGS. 17A and 17B, the map information is not used and the position is not displayed. Only the positional relationship between the other vehicle obtained based on the information and the host vehicle M and / or the destination of the host vehicle M may be displayed on the display panel 5a.

By the way, in order to accurately notify the position of the other vehicle, it is sufficient to increase the frequency of information transmission requests to the management organization and to frequently receive the position information of the other vehicle. It will increase. Therefore, in the terminal device according to another embodiment, the position information of other vehicles and the information related to the update time in the position information are accumulated, and based on the accumulated position information, update time information, and destination information. Thus, the current position of the other vehicle may be estimated, and the other vehicle may be notified based on the estimated result to reduce the number of communication and the amount of communication data.

Moreover, in the information provision system comprised including the terminal device which concerns on the said Embodiment (1) or (2), and a provision apparatus, such as a positional information, it demonstrates only about the case where notification restriction of other vehicles is performed on the terminal device side.
