First, the meeting point determination process (shortest time) in FIG. 8 will be described.

The server device 10 reads the latest current position information of the representative moving body 20 and the subordinate moving body 30 in the movement history stored in the storage unit 16 (S110). Moreover, the server apparatus 10 calculates the average moving speed as the moving capability of the representative moving body 20 and the subordinate moving body 30 based on the moving history memorize | stored in the memory | storage part 16 (S120). In addition, the server device 10 receives information about weather (specifically, temperature, wind direction, and environmental conditions) around the current position of the representative mobile body 20 and the subordinate mobile body 30 from a weather data server connected via a communication network. Wind speed) is acquired (S130). In addition, the order of acquisition of the information on the current position information, the average moving speed, and the weather is arbitrary. As for the average moving speed, for example, information that can predict the average moving speed of each moving object or general average moving speed such as age and gender is stored in a group database or the like and used. Then, the average moving speed (moving ability) may be acquired. Also, information on the weather may be acquired from each mobile body by transmitting information on the weather together with the current position information in each mobile body.

Next, as shown in FIG. 10A, the server device 10 has the same length for the representative moving body 20 and the subordinate moving body 30 centered on the current positions A and B, according to the average moving speed. A circle having a radius that can be reached in the movable range calculation time (for example, the initial value is 5 minutes) (a perfect circle) is calculated as the movable range (S140).

Next, the server device 10 determines whether or not the temperature around the current position of the representative mobile body 20 and the subordinate mobile body 30 is equal to or higher than a predetermined temperature determination threshold (for example, 25 ° C.) (S150). When the temperature around each moving body is equal to or higher than the temperature determination threshold value (Y in S150), the movable range is reduced in all radial directions (that is, the radius of the perfect circle is reduced) and corrected (S160). Alternatively, when the temperature is lower than the temperature determination threshold (N in S150), the size of the movable range is maintained.

Next, the server device 10 determines whether or not the wind speed around the current position of the representative mobile body 20 and the subordinate mobile body 30 is equal to or higher than a predetermined wind speed determination threshold (for example, 5 m / sec) (S170). When the wind speed around each moving body is equal to or higher than the wind speed determination threshold (Y in S170), as shown in FIG. 10B, the current position (ie, the center) of the moving body in the movable range is upwind ( The shape of the movable range is corrected such that the radius is reduced in the radial direction toward the left (in the drawing) and enlarged in the radial direction toward the leeward (to the right in the drawing) (S180). Alternatively, when the wind speed is less than the wind speed determination threshold (N in S170), the shape of the movable range is maintained.

Next, the server device 10 determines whether or not the movable range of the representative mobile body 20 and the movable range of the dependent mobile body 30 overlap (S190).

As shown in FIG. 10B, the server device 10 determines the above-described movable range calculation time if the movable range of the representative mobile body 20 and the movable range of the dependent mobile body 30 do not overlap (N in S190). Is increased (for example, +5 minutes) (S200) so that the movable range of each mobile object becomes larger, the movable range is calculated and corrected again, and the overlapping of the movable ranges is determined (S140). To S190).

Alternatively, as illustrated in FIG. 10C, the server device 10 stores in the storage unit 16 if the movable range of the representative mobile body 20 and the movable range of the dependent mobile body 30 overlap (Y in S190). The stored merge purpose information is read (S210), and the facility database 15 retrieves the facility whose utilization purpose matches the merge purpose and closest to the center position O of the overlapping portion of the movable range. The resulting facility is determined as a meeting point (S220). And the information (joining point information) regarding the name and location of the facility determined as the joining point is transmitted to each mobile unit (S230). Further, at this time, the movable range calculation time used for calculating the merging point is transmitted to each moving body as information of the merging scheduled time (scheduled merging time information). 7B may be added to the merged point set screen B2 shown in FIG. 7 (b) with “additional scheduled time is after XX minutes”. Then, the merge point determination process (shortest time) is terminated.

Subsequently, the meeting point determination process (specified time) in FIG. 9 will be described.

The server device 10 reads the latest current position information of the representative moving body 20 and the subordinate moving body 30 in the movement history stored in the storage unit 16 (T110). Further, the server device 10 calculates the average moving speed as the moving ability of the representative moving body 20 and the subordinate moving body 30 based on the moving history stored in the storage unit 16 (T120). In addition, the server device 10 receives information about weather (specifically, temperature, wind direction, and environmental conditions) around the current position of the representative mobile body 20 and the subordinate mobile body 30 from a weather data server connected via a communication network. Wind speed) is acquired (T130).

Next, the server device 10 reads the information of the designated joining time stored in the storage unit 16 (T135).

A circle having a radius that is reachable by the length of time indicated by time (a perfect circle) is calculated as a movable range (T140).

Next, the server device 10 determines whether the temperature around the current position of the representative mobile body 20 and the subordinate mobile body 30 is equal to or higher than a predetermined temperature determination threshold (for example, 25 ° C.) (T150). When the temperature around each moving body is equal to or higher than the temperature determination threshold value (Y in T150), the movable range is reduced in all radial directions (that is, the radius of the perfect circle is reduced) and corrected (T160). Alternatively, when the temperature is lower than the temperature determination threshold (N in T150), the size of the movable range is maintained.

Next, the server device 10 determines whether or not the wind speed around the current position of the representative mobile body 20 and the subordinate mobile body 30 is equal to or higher than a predetermined wind speed determination threshold (for example, 5 m / second) (T170). When the wind speed around each moving body is equal to or higher than the wind speed determination threshold (Y in T170), as shown in FIG. 10B, the current position (that is, the center) of the moving body in the movable range is upwind ( The shape of the movable range is corrected by reducing the radius in the radial direction toward the left (in the drawing) and increasing the radius in the radial direction toward the leeward (in the right in the drawing) (T180). Alternatively, when the wind speed is less than the wind speed determination threshold (N in T170), the shape of the movable range is maintained.

Next, the server device 10 determines whether or not the movable range of the representative mobile body 20 and the movable range of the dependent mobile body 30 overlap (T190).

As shown in FIG. 10B, the server device 10 does not have an appropriate joining point unless the movable range of the representative mobile body 20 and the movable range of the dependent mobile body 30 overlap (N in T190). It is determined that there is no merging point, and merging point information indicating that there is no merging point is transmitted to each mobile unit (T230). Then, the merge point determination process (specified time) is terminated.

Alternatively, as illustrated in FIG. 10C, the server device 10 stores in the storage unit 16 if the movable range of the representative mobile body 20 and the movable range of the dependent mobile body 30 overlap (Y in T190). The stored merge purpose information is read (T210), and the facility database 15 retrieves the facility whose utilization purpose matches the merge purpose and closest to the central position O of the overlapping portion of the movable range. The resulting facility is determined as a meeting point (T220). And the information (merging point information) regarding the name and location of the facility determined as the confluence is transmitted to each mobile unit (T230). In addition, at this time, the designated merging time used for calculating the merging point is transmitted to each moving body as information on the merging scheduled time (scheduled merging time information). Also good. Then, the merge point determination process (specified time) is terminated.

The steps corresponding to steps S110 and T110 in the flowcharts of FIGS. 8 and 9 described above correspond to an example of the current position information acquisition step, and the steps corresponding to steps S120 and T120 are examples of the movement capability information acquisition step. The process corresponding to steps S130 and T130 corresponds to the environmental state information acquisition process, and the process corresponding to step T135 corresponds to an example of the designated joining time information acquisition process, and steps S140 to S200, S220, and T140. The processes corresponding to T200 and T220 correspond to an example of a joining point determination process, and the processes corresponding to S210 and T210 correspond to an example of a joining purpose information acquisition process.

mobile bodies

30 and 40, and the control unit 11 performs the representative movement based on the movement history stored in the storage unit 16. Since the average movement speed of each of the body 20 and the subordinate

Although the present invention has been described with reference to the preferred embodiment, the present invention is not limited to the configuration of the above embodiment.

For example, in the above-described embodiment, the server device 10 determines and outputs one merging point, but is not limited to this. For example, the server apparatus 10 installs one or a plurality of facilities included in a predetermined range (for example, a range having a radius of 100 m) from the center of the overlapping portion of the movable range of the representative mobile body 20 and the subordinate

mobile bodies

30 and 40. It is good also as a structure which obtains from the database 15 and determines and outputs these 1 or several facilities as 1 or several junctions.

In such a configuration, when a plurality of joining points are determined by the server device 10, the sequence shown in FIG. 11 is executed instead of the sequence shown in FIG. The sequence shown in FIG. 11 will be described below.

As shown in FIG. 11, when the server device 10 determines a plurality of joining points, the server device 10 transmits the joining point information (joining point information) only to the representative moving body 20 (T40).

When the representative moving body 20 receives the joining point information indicating the plurality of joining points, the representative moving body 20 displays the joining point selection screen A7 shown in FIG. 12 (T51). Then, when “store P” is selected from the displayed list of merging points and the “decision” button is pressed (T52), the representative mobile body 20 receives information on the selected merging point (selected merging point information). ) Is transmitted to the server device 10 (T53).

In the above-described embodiment, the movable range is corrected based on the temperature, wind speed, and wind direction around the current position of each moving body. However, the present invention is not limited to this. In addition to these, for example, the movable range may be corrected using information on weather such as weather and humidity as information on the environmental state.

Alternatively, the movable range may be corrected based on information about the area as the environmental state information. As the information regarding the area, for example, the number of signals per unit area obtained from the map database 13 is used. In areas where the number of signals per unit area is small, the moving average speed is improved and the movable range is widened, and in areas where the number of signals per unit area is large, the moving average speed is lowered and the movable range is narrowed. Therefore, in the server device 10, when the number of signals per unit area is equal to or smaller than the predetermined first threshold, the radius of the movable range is expanded, and the number of signals is larger than the first threshold and the second threshold (however, the second threshold). > 1st threshold) or less, the movable range is maintained, and when the number of signals is greater than the second threshold, the radius of the movable range is reduced to correct the shape of the movable range. By doing in this way, a movable range can be calculated | required according to the actual condition.

Or, for example, the slope of the land may be used as information about the area. For example, as shown in FIGS. 13A and 13B, when the current positions of the representative moving body 20 and the subordinate moving body 30 are on the inclined land, the land moves down the inclined land (moves to the left in the figure). In some cases, the average moving speed is improved and the movable range is widened, and when climbing an inclined land (moving in the right direction in the figure), the average moving speed is lowered and the movable range is narrowed. Therefore, in the server device 10, when the degree of slope of the land (gradient) is equal to or greater than a predetermined threshold, the radius is increased in the radial direction toward the downward direction and the radius is reduced in the radial direction toward the upward direction. In this way, the shape of the movable range is corrected. By doing in this way, a movable range can be calculated | required according to the actual condition.

Further, in this embodiment, the facility closest to the center of the overlapping portion of the movable range of each moving object is the joining point, but is not limited to this, for example, the center of the overlapping portion As long as it does not contradict the purpose of the present invention, the method for determining the merge point is arbitrary as long as it is determined based on the overlapping portion of the movable range.

Further, in this embodiment, the navigation device 50 arranged in the representative moving body 20 and the subordinate moving

bodies

30 and 40 is the same, and the moving body that requests the joining is the representative moving body 20 and the joining is requested. Although the mobile body is the subordinate

mobile bodies

30 and 40, it is not limited to this. For example, it is possible to request joining only for the navigation device 50 arranged in the representative mobile body 20, and the navigation device 50 arranged in the subordinate

mobile bodies

30, 40 can only be requested to join. It may be a configuration.

In this embodiment, the map data to be displayed on the navigation device 50 is stored in the navigation device 50. However, the navigation device 50 receives the map data from the server device 10 or another server device. May be.

In the present embodiment, the display unit 57 is shown as the providing unit. However, each piece of information including the joining point information may be provided by voice from the voice output unit 58. In addition, the display unit 57 and the audio output unit 58 may be used together to provide each information with images (characters) and audio. Further, in the sequence of FIGS. 4, 5, and 11, the operation unit 56 is used at the time of operation input, but voice input may be used.

Further, the terminal device is not limited to the navigation device 50, and may be a mobile terminal such as a mobile phone or a smartphone, or a tablet personal computer. Further, the terminal device arranged on the mobile body may not have the guidance function (navigation function), and may receive the guidance information to the destination from the server device 10.

Further, the function of the server device 10 may be included in a terminal device such as one navigation device. In this case, the terminal device corresponds to an example of an information processing device.
