[0040] Some or all of the functions of the terminal device 30 may be realized by a programmable circuit or a dedicated circuit as the control unit 31. In other words, some or all of the functions of the terminal device 30 may be realized by hardware.

[0041] The operation of the system 10 according to this embodiment will be described with reference to Fig. 4. This operation corresponds to the notification method according to this embodiment.

[0042] In step S1, the control unit 21 of the control device 20 refers to the first position data D2 and calculates the estimated arrival time Ta at which the user 11 will arrive at the stop point 13 where the vehicle 12 is stopping. The first position data D2 is data indicating the position of the user 11. The specific procedure of the processing in step S1 will be described.

[0043] The positioning unit 36 ​​of the terminal device 30 measures the position of the terminal device 30 as the position of the user 11. The control unit 31 of the terminal device 30 causes the communication unit 33 to transmit the result of measurement of the position of the user 11 by the positioning unit 36 ​​as first position data D2. The communication unit 33 transmits the first position data D2 to the control device 20. The communication unit 23 of the control device 20 receives the first position data D2 from the terminal device 30. The control unit 21 of the control device 20 acquires the first position data D2 received by the communication unit 23. The control unit 21 refers to map data D3 and calculates the distance between the position indicated by the acquired first position data D2 and the stop point 13. The map data D3 is data that defines the stop point 13. The map data D3 may be pre-stored in the storage unit 22 of the control device 20 or may be accumulated in an external system, such as a GIS on the Internet. "GIS" is an abbreviation for geographic information system. The control unit 21 divides the calculated distance by the average human walking speed to calculate the time required to travel from the position of the user 11 to the stop point 13. The control unit 21 adds the calculated time required to the current time to calculate the estimated arrival time Ta.

[0044] In step S2, the control unit 21 of the control device 20 refers to the second position data D4 to calculate the scheduled departure time Td at which the vehicle 12 departs from the stop point 13. The second position data D4 is data indicating the position of the vehicle 12. The specific procedure of the processing in step S2 will be described.

[0045] The communication unit 23 of the control device 20 receives, from the vehicle 12, the result of measurement of the position of the vehicle 12 by a GNSS receiver mounted on the vehicle 12, as second position data D4. The control unit 21 of the control device 20 acquires the second position data D4 received by the communication unit 23. The control unit 21 refers to the map data D3 and calculates the distance between the position indicated by the acquired second position data D4 and the stop point 13. The control unit 21 calculates the required time from the position of the vehicle 12 to the stop point 13 by dividing the calculated distance by the average vehicle speed. The control unit 21 predicts the time when the vehicle 12 will stop at the stop point 13 by adding the calculated required time to the current time. The control unit 21 calculates the scheduled departure time Td by adding a predetermined stop time to the predicted time.

[0046] In step S3, the control unit 21 of the control device 20 compares the estimated arrival time Ta calculated in step S1 with the scheduled departure time Td calculated in step S2. The control unit 21 determines the content of the notification data D1 according to the result of comparing the estimated arrival time Ta with the scheduled departure time Td. The notification data D1 is data transmitted to the terminal device 30 by the communication unit 23 of the control device 20 in step S4. The specific procedure of the processing in step S3 will be described with reference to FIG. 5.

[0047] In step S301, the control unit 21 of the control device 20 determines whether the estimated arrival time Ta is later than the scheduled departure time Td. If it is determined that the estimated arrival time Ta is later than the scheduled departure time Td, the process of step S302 is executed. If it is determined that the estimated arrival time Ta is earlier than the scheduled departure time Td, the process of step S305 is executed. If it is determined that the estimated arrival time Ta is the same as the scheduled departure time Td, the process of step S302 may be executed, but in this embodiment, the process of step S305 is executed.

[0048] In step S302, the control unit 21 of the control device 20 determines whether the time difference between the estimated arrival time Ta and the scheduled departure time Td is smaller than a threshold value Th. In this embodiment, the threshold value Th is a fixed value such as 10 seconds, 30 seconds, or 1 minute, but may be a variable value that changes depending on the distance calculated in step S1 or other parameters. If it is determined that the time difference between the estimated arrival time Ta and the scheduled departure time Td is smaller than the threshold value Th, the control unit 21 executes the process of step S303. If it is determined that the time difference between the estimated arrival time Ta and the scheduled departure time Td is greater than the threshold value Th, the control unit 21 executes the process of step S304. If it is determined that the time difference between the estimated arrival time Ta and the scheduled departure time Td is equal to the threshold value Th, the control unit 21 may execute the process of step S303, but in this embodiment, the control unit 21 executes the process of step S304.

[0049] In step S303, the control unit 21 of the control device 20 includes in the notification data D1 data notifying the user 11 that the user 11 will make it to the vehicle 12 if the user runs. The control unit 21 may further include in the notification data D1 data notifying the user 11 of the scheduled departure time Td. Alternatively, the control unit 21 may further include in the notification data D1 data notifying the user 11 of the distance calculated in step S1. Alternatively, the control unit 21 may further include in the notification data D1 data notifying the user 11 of the time difference between the estimated arrival time Ta and the scheduled departure time Td. After step S303, the processing of step S4 is executed.

[0050] In step S304, the control unit 21 of the control device 20 includes in the notification data D1 data notifying the user 11 that even if the user 11 runs, he or she will not make it to the vehicle 12. The control unit 21 may further include in the notification data D1 data notifying the user 11 of the time Tn at which the vehicle following the vehicle 12 will depart from the stop point 13. The time Tn may be calculated in the same manner as the scheduled departure time Td, or may be determined in advance. After step S304, the processing of step S4 is executed.

[0051] In step S305, the control unit 21 of the control device 20 omits sending the notification data D1. That is, after step S305, the process of step S4 is skipped.

[0052] In step S4, the control unit 21 of the control device 20 presents the notification data D1 to the user 11 via the terminal device 30. The specific procedure for this process will be described below.

[0053] The control unit 21 of the control device 20 causes the communication unit 23 to transmit the notification data D1. The communication unit 23 transmits the notification data D1 to the terminal device 30. The communication unit 33 of the terminal device 30 receives the notification data D1 from the control device 20. The control unit 31 of the terminal device 30 acquires the notification data D1 received by the communication unit 33. The control unit 31 presents the acquired notification data D1 to the user 11. Any method may be used to present the notification data D1 to the user 11, but in this embodiment, a method is used in which the content of the notification data D1 is displayed on a display serving as the output unit 35 of the terminal device 30. Alternatively, a method may be used in which the content of the notification data D1 is output as audio from a speaker serving as the output unit 35.

[0054] For example, if the user 11 has reserved the vehicle 12 the day before, when the user 11 leaves home on the day, the processes from step S1 to step S4 are executed and a notification is sent to the user 11.

[0055] The scheduled departure time Td may be predetermined instead of being calculated in step S2. In such a modified example, the processing of step S2 is omitted. In step S3, the control unit 21 of the control device 20 refers to the schedule data D5 to identify the scheduled departure time Td. The schedule data D5 is data that defines the scheduled departure time Td. The schedule data D5 is pre-stored in the memory unit 22 of the control device 20 or in an external storage. The control unit 21 compares the estimated arrival time Ta calculated in step S1 with the identified scheduled departure time Td. The control unit 21 determines the content of the notification data D1 depending on the result of comparing the estimated arrival time Ta with the scheduled departure time Td.

[0056] If the estimated arrival time Ta is later than the scheduled departure time Td and the time difference between the estimated arrival time Ta and the scheduled departure time Td is smaller than the threshold Th, the user 11 may be notified that he or she will make it to the vehicle 12 if he or she runs, after confirming that the user 11 is walking. If the user 11 is running, it is assumed that the user 11 will make it to the vehicle 12, so the notification may be omitted. Similarly, if the estimated arrival time Ta is later than the scheduled departure time Td and the time difference between the estimated arrival time Ta and the scheduled departure time Td is larger than the threshold Th, the user 11 may be notified that he or she will not make it to the vehicle 12 even if he or she runs, after confirming that the user 11 is running. If the user 11 is walking, it is assumed that the user 11 has given up on getting on the vehicle 12, so the notification may be omitted. A specific procedure of the processing of step S3 in such a modified example will be described with reference to FIG. 6 .

[0057] In step S311, the control unit 21 of the control device 20 determines whether the estimated arrival time Ta is later than the scheduled departure time Td, as in step S301. If it is determined that the estimated arrival time Ta is later than the scheduled departure time Td, the process of step S312 is executed. If it is determined that the estimated arrival time Ta is earlier than the scheduled departure time Td, the process of step S317 is executed. If it is determined that the estimated arrival time Ta is the same as the scheduled departure time Td, the process of step S312 may be executed, but in this modified example, the process of step S317 is executed.

[0058] In step S312, the control unit 21 of the control device 20 determines whether the time difference between the estimated arrival time Ta and the scheduled departure time Td is smaller than the threshold value Th, as in step S302. If it is determined that the time difference between the estimated arrival time Ta and the scheduled departure time Td is smaller than the threshold value Th, the process of step S313 is executed. If it is determined that the time difference between the estimated arrival time Ta and the scheduled departure time Td is larger than the threshold value Th, the process of step S315 is executed. If it is determined that the time difference between the estimated arrival time Ta and the scheduled departure time Td is equal to the threshold value Th, the process of step S313 may be executed, but in this modified example, the process of step S315 is executed.

[0059] In step S313, the communication unit 23 of the control device 20 receives data D6 from the terminal device 30, such as a result of measuring the position of the user 11 two or more times at intervals by the positioning unit 36 ​​of the terminal device 30, or a result of measuring the moving speed of the user 11 by a built-in sensor of the terminal device 30. The control unit 21 of the control device 20 determines whether the user 11 is walking by referring to the data D6 from the terminal device 30 received by the communication unit 23. The control unit 21 may use the first position data D2 acquired in step S1 as part of the data D6 from the terminal device 30. If it is determined that the user 11 is walking, the process of step S314 is executed. If it is determined that the user 11 is running, the process of step S317 is executed. If it is determined that the user 11 is standing still, the process of step S314 may be executed, but in this modified example, the process of step S317 is executed.

[0060] The process of step S314 is the same as the process of step S303, and therefore a description thereof will be omitted. After step S314, the process of step S4 is executed.

[0061] In step S315, the communication unit 23 of the control device 20 receives data D7 from the terminal device 30, such as a result of measuring the position of the user 11 two or more times at intervals by the positioning unit 36 ​​of the terminal device 30, or a result of measuring the moving speed of the user 11 by a built-in sensor of the terminal device 30. The control unit 21 of the control device 20 determines whether the user 11 is running by referring to the data D7 from the terminal device 30 received by the communication unit 23. The control unit 21 may use the first position data D2 acquired in step S1 as part of the data D7 from the terminal device 30. If it is determined that the user 11 is running, the process of step S316 is executed. If it is determined that the user 11 is walking, the process of step S317 is executed. If it is determined that the user 11 is standing still, the process of step S317 is also executed.

[0062] The processes in steps S316 and S317 are the same as those in steps S304 and S305, respectively, and therefore will not be described here. After step S316, the process in step S4 is executed. After step S317, the process in step S4 is skipped.

[0063] As shown in FIG. 7 , a person moving toward the stop point 13 at a detection speed Sd or faster within a detection range Rd around the stop point 13 may be detected as a passenger candidate 14. In such a modified example, when the passenger candidate 14 is detected, the control unit 21 of the control device 20 may cause the vehicle 12 to continue stopping even if the scheduled departure time Td has passed. Alternatively, when the passenger candidate 14 is detected, the control unit 21 may notify the driver of the vehicle 12, a crew member responding to an emergency, or an operator remotely operating the vehicle 12 of the presence of the passenger candidate 14. In step S303 or step S314, the control unit 21 may further include data notifying the user 11 of the detection range Rd, the detection speed Sd, or both, in the notification data D1. The detection range Rd is set to a certain range centered on the stop point 13, such as a circle with a radius of 40 meters centered on the stop point 13. The detection speed Sd is set to a speed faster than the average human walking speed, such as 5 kilometers per hour.

[0064] As described above, in this embodiment, the communication unit 23 of the control device 20 receives first position data D2 from the terminal device 30. The first position data D2 is data indicating the position of the user 11. The control unit 21 of the control device 20 refers to the first position data D2 received by the communication unit 23 and calculates the estimated arrival time Ta at which the user 11 will arrive at the stop point 13 where the vehicle 12 will stop. The control unit 21 determines the content of the notification data D1 based on the result of comparing the calculated estimated arrival time Ta with the scheduled departure time Td at which the vehicle 12 will depart from the stop point 13. The notification data D1 is data transmitted to the terminal device 30 by the communication unit 23.

[0065] According to this embodiment, it is easy to prevent reckless jumping on a train. Therefore, it is easy to avoid a situation where a user 11 gets caught in the door when trying to jump on a train 12, causing a delay. As a result, it is possible to suppress disruptions to the train schedule.

[0066] Although the stop point 13 is fixed in this embodiment, it may be changed as appropriate. In such a modified example, the control unit 21 of the control device 20 includes proposal data D8 in the notification data D1 when the estimated arrival time Ta is later than the scheduled departure time Td. The proposal data D8 is data that suggests to the user 11 that the stop point 13 be changed to a location closer to the user 11. If the stop point 13 is changed as suggested, a fee may be requested from the user 11.

[0067] The stop point 13 may be dynamically set. In such a modified example, the control unit 21 of the control device 20 sets the stop point 13 according to the position indicated by the first position data D2 and the position of the vehicle 12. The control unit 21 notifies the user 11 and the vehicle 12 of the set stop point 13.

[0068] The present disclosure is not limited to the above-described embodiments. For example, two or more blocks shown in the block diagrams may be integrated, or one block may be divided. Two or more steps shown in the flowcharts may be executed in parallel or in a different order, instead of being executed in chronological order as described, depending on the processing capabilities of the device executing each step, or as needed. Other modifications are possible within the scope of the present disclosure.

[0069] For example, the terminal device 30 may calculate the estimated arrival time Ta instead of the control device 20. Alternatively, the terminal device 30 may determine the content of the notification data D1 based on the result of comparing the estimated arrival time Ta with the scheduled departure time Td instead of the control device 20. The operation of the system 10 in such a modified example will be described with reference to FIG.

[0070] In step S1, the control unit 31 of the terminal device 30 calculates the estimated arrival time Ta by referring to the results of measuring the position of the user 11. The specific procedure of this process will be described.

[0071] The positioning unit 36 ​​of the terminal device 30 measures the position of the terminal device 30 as the position of the user 11. The control unit 31 of the terminal device 30 refers to map data D3 and calculates the distance between the position measured by the positioning unit 36 ​​and the stop point 13. The map data D3 may be pre-stored in the storage unit 32 of the terminal device 30, or may be accumulated in an external system such as a GIS on the Internet. The control unit 31 calculates the required time from the position of the user 11 to the stop point 13 by dividing the calculated distance by the average human walking speed. The control unit 31 calculates the estimated arrival time Ta by adding the calculated required time to the current time.

[0072] In step S2, the control unit 31 of the terminal device 30 refers to the second position data D4 to calculate the scheduled departure time Td. The specific procedure for this process will be described.

[0073] The communication unit 33 of the terminal device 30 receives, from the vehicle 12, the result of measurement of the position of the vehicle 12 by a GNSS receiver mounted on the vehicle 12, as second position data D4. The control unit 31 of the terminal device 30 acquires the second position data D4 received by the communication unit 33. The control unit 31 refers to the map data D3 and calculates the distance between the position indicated by the acquired second position data D4 and the stop point 13. The control unit 31 calculates the required time from the position of the vehicle 12 to the stop point 13 by dividing the calculated distance by the average vehicle speed. The control unit 31 predicts the time when the vehicle 12 will stop at the stop point 13 by adding the calculated required time to the current time. The control unit 31 calculates the scheduled departure time Td by adding a predetermined stop time to the predicted time.

[0074] In step S3, the control unit 31 of the terminal device 30 compares the estimated arrival time Ta calculated in step S1 with the scheduled departure time Td calculated in step S2. The control unit 31 determines the content of the notification data D1 based on the result of comparing the estimated arrival time Ta with the scheduled departure time Td. The specific steps of the processing in step S3 are the same as those shown in Figure 5 or 6, so their explanation will be omitted.

[0075] In step S4, the control unit 31 of the terminal device 30 presents the notification data D1 to the user 11. The method for presenting the notification data D1 to the user 11 has already been described.

[0076] In this variant, the control device 20 may be omitted. [Explanation of symbols]
