The communication system 10 according to this embodiment includes at least one control device 20, at least one terminal device 30, and at least one communication device 40.

The control device 20 can communicate with the terminal device 30 and the communication device 40 via a network 50.

The network 50 includes the Internet, at least one WAN, at least one MAN, or a combination of these networks. “WAN” is an abbreviation for wide area network. “MAN” is an abbreviation for metropolitan area network. The network 50 may include at least one wireless network, at least one optical network, or a combination of these networks. The wireless network is, for example, an ad hoc network, a cellular network, a wireless LAN, a satellite communication network, or a terrestrial microwave network. “LAN” is an abbreviation for local area network.

The control device 20 is installed in a facility such as a data center. The control device 20 is a server belonging, for example, to a cloud computing system or any other types of computing systems.

The terminal device 30 is carried by a user. The terminal device 30 is a mobile device, such as a mobile phone, a smartphone, or a tablet, or is a PC. “PC” is an abbreviation for personal computer.

The communication device 40 is mounted or installed in a vehicle 12 such as a taxi or an on-demand bus. Instead of being mounted or installed in the vehicle 12, the communication device 40 is sometimes carried by the driver of the vehicle 12. The communication device 40 is, for example, an in-vehicle device such as a car navigation device, or is a mobile device such as a mobile phone, a smartphone, or a tablet, or is a PC.

The vehicle 12 is any type of automobile, including a gasoline vehicle, a diesel vehicle, an HV, a PHV, an EV, or an FCV. “HV” is an abbreviation for hybrid vehicle. “PHV” is an abbreviation for plug-in hybrid vehicle. “EV” is an abbreviation for electric vehicle. “FCV” is an abbreviation for fuel cell vehicle. Although driven by a driver in this embodiment, the vehicle 12 may be driven autonomously at any autonomous driving level. The autonomous driving level is, for example, one of level 1 to level 5 of SAE autonomous driving levels. “SAE” is an abbreviation for Society of Automotive Engineers. The vehicle 12 may be a MaaS vehicle. “MaaS” is an abbreviation for Mobility as a Service.

The outline of this embodiment will be described below with reference to FIG. 1.

In this embodiment, the communication device 40 used in the vehicle 12 sends the signal. When the signal sent from the communication device 40 is received, the terminal device 30 carried by a user 11 determines whether the user 11 is in the vehicle 12 according to at least one of whether the destination has been set by the user 11 and whether the vehicle dispatch application, which is a program for receiving the vehicle dispatch service, is activated.

This embodiment makes it easy to prevent an erroneous determination that the user 11 is in the vehicle 12, improving the accuracy in determining whether the user 11 is in the vehicle.

In this embodiment, the terminal device 30 sends first data to the control device 20. The first data notifies about the destination set by the user 11 together with the user identifier corresponding to the user 11. The control device 20 receives the first data from the terminal device 30.

In response to an operation of the user 11, the terminal device 30 acquires the vehicle identifier corresponding to the vehicle 12 in which the user 11 is travelling. The terminal device 30 sends second data to the control device 20. The second data notifies about the acquired vehicle identifier together with the user identifier corresponding to the user 11. The control device 20 receives the second data from the terminal device 30.

The control device 20 refers to the first data and the second data both of which have a common user identifier and, then, sends the destination data, which notifies about the destination, to the communication device 40. The communication device 40 receives the destination data from the control device 20.

According to this embodiment, the information on the destination, which is set by the user 11, can be used for setting the destination of the vehicle 12 in which the user 11 is travelling. For example, using the information on the destination for multimodal navigation or single-modal navigation that has been entered by the user 11 into the terminal device 30, the communication device 40 can set the destination for car navigation. “Multimodal navigation” is navigation in which a multimodal route is guided. The “multimodal route” is a route on which the user will move using a combination of one or more means of transportation selected from among a plurality of types of transportation including the vehicle 12. The “plurality means of transportation” includes, for example, a taxi that is the vehicle 12 and, in addition, may include various means of transportation such as walking, a bicycle, a bus, a rental car, a private car, a railroad, or an airplane. “Single-modal navigation” is navigation in which a single-modal route is guided. The “single-modal route” is a route on which the user will move using one of the means of transportation, either first means of transportation including the vehicle 12 or the second means of transportation not including the vehicle 12, whichever is selected by the user 11. The “first means of transportation” is, for example, a taxi that is the vehicle 12, and may include accompanying means of transportation such as walking or a bicycle. The “second means of transportation” is, for example, a bus or a railroad, which is public transportation, or a combination thereof and may include accompanying means of transportation such as walking or a bicycle.

In this embodiment, the destination is set, the user 11 is determined to be in the vehicle 12, and the riding procedure operation is performed and, after that, the control device 20 determines the route to the destination based on the position data on the vehicle 12. The control device 20 sends the route data, which notifies about the determined route, to the communication device 40. The communication device 40 receives the route data from the control device 20. By referring to the received route data, the communication device 40 guides the driver of the vehicle 12 along the route to the destination. That is, after the riding procedure operation is performed, the communication device 40 guides the driver of the vehicle 12 to the destination according to the position data on the vehicle 12. Note that, instead of the control device 20, the communication device 40 may determine the route that is output to guide the driver of the vehicle 12.

The “riding procedure operation” is an operation to acquire the vehicle identifier corresponding to the vehicle 12 in which the user 11 is travelling. Such operations include, for example, an operation to point the camera of the terminal device 30 at the display that displays the vehicle identifier in the vehicle cabin of the vehicle 12 or an operation to place the tag of the terminal device 30 over the reader/writer that sends the vehicle identifier in vehicle cabin of the vehicle 12.

The operation of the communication system 10 according to this embodiment will be described with reference to FIG. 5, FIG. 6, and FIG. 7. This operation corresponds to the riding determination method according to this embodiment.

FIG. 5 shows the general processing flow of the communication system 10 according to this embodiment.

In one example described below, it is assumed that the user 11 has activated a multimodal navigation application on the terminal device 30 of the user 11. It is also assumed that the user 11 has set the destination by entering it from the input unit 34 of the terminal device 30 (step S110).

In step S111 in FIG. 5, the communication unit 33 of the terminal device 30 of the user 11 receives the beacon sent in the cabin of the vehicle 12 in which the user 11 is riding. The beacon may be sent and received using any communication method, for example, via Bluetooth (registered trademark). This beacon, when received by the communication unit 33, acts as a trigger to cause the control unit 31 of the terminal device 30 to determine, in step S112, whether the user 11 is in the vehicle 12.

FIG. 6 shows a detailed processing flow of the riding determination processing performed in step S112 in FIG. 5. The processing in FIG. 6 is performed by the control unit 31 of the terminal device 30.

First, in step S113, the control unit 31 checks whether the destination has been set. The destination is set by the user 11 via the input unit 34 of the terminal device 30. When the destination has not been set, the control unit 31 determines that the user 11 is not in the vehicle 12. On the other hand, when the destination has been set, the processing of the control unit 31 proceeds to step S114. In this example, since the destination has been set, the processing of the control unit 31 proceeds to step S114.

Next, in step S114, the control unit 31 checks whether the user 11 is moving to the destination by another vehicle at the time when the signal sent from the communication device 40 is received. Another vehicle mentioned here refers to a vehicle other than the vehicle 12. To determine whether the user 11 is moving by another vehicle, the control unit 31 uses, for example, the GPS function of the positioning unit 36 of the terminal device 30 or the motion detection sensor provided in the terminal device 30 to check whether the terminal device 30 is moving at a speed. Alternatively, the control unit 31 may check the riding determination history of the terminal device 30 and, based on the time when the user 11 was determined to ride last, determine whether the user 11 is moving by another vehicle. When the user 11 is moving to the destination by another vehicle at the time when the signal sent from the communication device 40 is received, the control unit 31 determines that the user 11 is not in the vehicle 12. When the user 11 is not moving to the destination by another vehicle at the time when the signal sent from the communication device 40 is received, the processing of the control unit 31 proceeds to step S115. In this example, since the user 11 is not moving to the destination by another vehicle, the processing of the control unit 31 proceeds to step S115.

Next, in step S115, the control unit 31 of the terminal device 30 checks whether a route on which the user 11 will move to the destination is being guided by the multimodal guidance function that guides a route on which the user will move using a combination of one or more means of transportation selected from among a plurality means of transportation including the vehicle 12. The multimodal guidance function is the function in which the control unit 31 guides a multimodal route for the user 11. When a route on which the user 11 will move to the destination using a combination of means of transportation including the vehicle 12 is not being guided by the multimodal guidance function, the control unit 31 determines that the user 11 is not in the vehicle 12. On the other hand, when a route on which the user will move to the destination using a combination of means of transportation including the vehicle 12 is being guided by the multimodal guidance function, the control unit 31 determines that the user 11 is in the vehicle 12. In this example, by means of the multimodal guidance function, the terminal device 30 is guiding a route on which the user will move to the destination using a combination of means of transportation including the vehicle 12. Therefore, the control unit 31 determines that the user 11 is in the vehicle 12.

After performing the processing described above, the control unit 31 ends the riding determination processing.

As described above, the determining by the terminal device 30 whether the user 11 is in the vehicle 12 includes determining whether the user 11 is in the vehicle 12 according to whether the destination has been set and whether or not the condition (C1) is satisfied that the user 11 is moving to the destination by another vehicle at the time when the signal sent from the communication device 40 is received. In FIG. 6, C1 is satisfied in step S114.

As described above, the terminal device 30 has the multimodal guidance function that guides a route on which the user will move using a combination of one or more means of transportation selected from among a plurality means of transportation including the vehicle 12. The determining by the terminal device 30 whether the user 11 is in the vehicle 12 includes determining whether the user 11 is in the vehicle 12 according to whether the destination has been set and whether or not the condition (C2) is satisfied that a route on which the user 11 will move to the destination using a combination of means of transportation including the vehicle 12 is being guided by the multimodal guidance function. In FIG. 6, C2 is satisfied in step S115.

Next, returning to FIG. 5, the control unit 31 generates first data notifying about the destination set by the user 11 together with the user identifier “U1” corresponding to the user 11. The control unit 31 stores the generated first data in the storage unit 32. The control unit 31 sends the first data, stored in the storage unit 32, to the control device 20 via the communication unit 33.

Next, in step S116, the control unit 31 displays a message to the user 11. In this example, the message to user 11 is displayed on the screen of the terminal device 30. Instead of being displayed on the screen of the terminal device 30, the message to user 11 may be output by voice, for example, through the speaker of the terminal device 30.

FIG. 7 shows an example of the screen of the terminal device 30. As shown in FIG. 7, the control unit 31 displays an icon indicating that the beacon has been received and a text message reading “Read the two-dimensional code to complete the riding procedure!” on the screen of the multimodal navigation application that is running in the terminal device 30.

In step S117, the terminal device 30 of user 11 is operated by the user 11.

In this example, the user 11 points the camera of the terminal device 30 at the display that displays the vehicle identifier “V1” in the cabin of the vehicle 12. In one modification, the user 11 may place the tag of the terminal device 30 over the reader/writer that sends the vehicle identifier “V1” in the cabin of the vehicle 12.

In step S118, the control unit 31 of the terminal device 30 of the user 11 acquires the vehicle identifier “V1” corresponding to the vehicle 12 in response to the operation of the user 11 in step S117. The control unit 31 generates second data notifying about the acquired vehicle identifier “V1” together with the user identifier “U1”. The control unit 31 stores the generated second data in the storage unit 32. The control unit 31 sends the second data, stored in the storage unit 32, to the control device 20 via the communication unit 33.

In this example, the control unit 31 of the terminal device 30 performs control to capture the vehicle identifier “V1”, displayed in the cabin of the vehicle 12, to acquire the vehicle identifier “V1”. More specifically, the control unit 31 performs control to capture the vehicle identifier “V1”, displayed in the form of a two-dimensional code, with the camera to acquire the vehicle identifier “V1”. In one modification, the control unit 31 may perform control to receive the vehicle identifier “V1”, sent in the cabin of the vehicle 12, to acquire the vehicle identifier “V1”. More specifically, the control unit 31 may perform control to receive the vehicle identifier “V1”, sent via near-field wireless communication, with the tag to acquire the vehicle identifier “V1”. The control unit 31 sends the acquired vehicle identifier “V1” to the control device 20 together with the user identifier “U1”.

In step S119, the control unit 21 of the control device 20 receives the second data from the terminal device 30 of the user 11 via the communication unit 23. The control unit 21 stores the received second data in the storage unit 22. The control unit 21 associates the user 11 with the vehicle 12 by referring to the first data and the second data both of which are stored in the storage unit 22 with the common user identifier “U1” The control unit 21 generates destination data notifying about the destination notified by the referenced first data. The control unit 21 stores the generated destination data in the storage unit 22. The control unit 21 sends the destination data, stored in the storage unit 22, to the communication device 40 in the vehicle 12, corresponding to the vehicle identifier “V1” notified by the referenced second data, via the communication unit 23. That is, the control unit 21 sends the destination data, which notifies about the destination set by the user 11, to the communication device 40 in the vehicle 12 associated with the user 11.

In this example, the control unit 21 of the control device 20 notifies the communication device 40, which is used in the vehicle 12 corresponding to the vehicle identifier “V1” sent from the terminal device 30 together with the user identifier “U1”, of the destination notified by the terminal device 30 together with the user identifier “U1”.

In step S120, the control unit 41 of the communication device 40 in the vehicle 12 receives the destination data, sent as a result of the processing in step S119, from the control device 20 via the communication unit 43. The control unit 41 stores the received destination data in the storage unit 42. The control unit 41 sets the destination based on the destination data stored in the storage unit 42.

In this example, the control unit 41 of the communication device 40 sets the destination, notified by the control device 20, in the car navigation application, running on the communication device 40, as the destination for car navigation.

In step S121, the control unit 41 of the communication device 40 in the vehicle 12 acquires the position data on the vehicle 12 via the positioning unit 46. The control unit 41 stores the acquired position data on the vehicle 12 in the storage unit 42. The control unit 41 sends the position data on the vehicle 12, stored in the storage unit 42, to the control device 20 via the communication unit 43.

In this example, the control unit 41 of the communication device 40 acquires the two-dimensional coordinates or the three-dimensional coordinates of the current position of the vehicle 12 as the position data on the vehicle 12. The control unit 41 sends the acquired position data on the vehicle 12, together with the vehicle identifier “V1”, to the control device 20.

In step S122, the control unit 21 of the control device 20 receives the position data on the vehicle 12, sent in step S121, from the communication device 40 in the vehicle 12 via the communication unit 23. The control unit 21 stores the received position data on the vehicle 12 in the storage unit 22. The control unit 21 determines a route to the destination, notified together with the user identifier “U1” in the first data stored in the storage unit 22, according to the position data on the vehicle 12 stored in the storage unit 22. The control unit 21 stores the route data, which notifies about the determined route, in the storage unit 22. The control unit 21 sends the route data, stored in the storage unit 22, to the communication device 40 in the vehicle 12 via the communication unit 23.

In this example, the control unit 21 of the control device 20 calculates a route by referring to the map information stored in advance in the storage unit 22. This route is from the point, corresponding to the position data on the vehicle 12 sent from the communication device 40 together with the vehicle identifier “V1”, to the destination notified by the terminal device 30 together with the user identifier “U1”. The control unit 31 notifies the communication device 40 of the calculated route.

In step S123, the control unit 41 of the communication device 40 in the vehicle 12 receives the route data, sent in step S122, from the control device 20 via the communication unit 43. The control unit 41 stores the received route data in the storage unit 42. The control unit 41 performs control to guide the driver of the vehicle 12 along the route notified in the form of the route data stored in the storage unit 42. According to this control, the output unit 45 of the communication device 40 outputs the route to the destination, set by the user 11, on the screen to guide the driver of the vehicle 12.

In this example, the control unit 41 of the communication device 40 displays the route, notified by the control device 20, on the screen of the car navigation application running on the communication device 40.

The processing from steps S121 to step S123 is repeatedly performed until the vehicle 12 arrives at the destination.

As described above, in this embodiment, the terminal device 30 includes the communication unit 33, which communicates with the communication device 40 used in the vehicle 12, and the control unit 31. When the signal sent from the communication device 40 is received via the communication unit 33, the control unit 31 determines whether the user 11 is in the vehicle 12 according to whether the destination has been set by the user 11.

When using the vehicle 12 to move, the user 11 sets the destination before riding in the vehicle 12. When the user 11 has not set the destination at the time the control unit 31 of the terminal device 30 receives the beacon emitted by the vehicle 12, there is a low possibility that the user 11 will use the vehicle 12. Taking this into account, even if the terminal device 30 of the user 11 who has not set the destination, that is, who does not intend to move by the vehicle 12, mistakenly receives the beacon emitted by the vehicle 12, the control unit 31 does not determine that the user 11 is in the vehicle 12. Therefore, this embodiment makes it easy to prevent an erroneous determination that the user 11 is in the vehicle 12, improving the accuracy in determining whether the user 11 is in the vehicle.

In one modification of this embodiment, the control unit 31 may determine whether the user 11 is in the vehicle, according to whether a route is being guided using the single-modal guidance function instead of the multimodal guidance function. In this case, the control unit 31 of the terminal device 30 has the single-modal guidance function. The single-modal guidance function guides a route on which the user 11 will move, using one of the means of transportation, either first means of transportation including the vehicle 12 or the second means of transportation not including the vehicle 12, whichever is selected by the user 11. When the destination has been set and, in addition, a route on which the user 11 will move to the destination using the second means of transportation is being guided by the single-modal guidance function, the control unit 31 determines that the user 11 is not in the vehicle 12.

The determination flow of the control unit 31 in this modification is shown in FIG. 8. In FIG. 8, the processing in step S115 in FIG. 6 is replaced by the processing in step S124. The processing other than that in step 124 is the same as the processing shown in FIG. 6.

Referring to FIG. 8, after the processing in step S113 and step S114, the control unit 31 checks whether a route on which the user 11 will move to the destination is being guided by the single-modal guidance function in which the second means of transportation is selected from the two means of transportation (first means of transportation including the vehicle 12 and second means of transportation not including the vehicle 12). The single-modal guidance function mentioned here is the function in which the control unit 31 guides a single-modal route for the user 11. When a route on which the user will move to the destination using the second means of transportation is being guided by the single-modal guidance function, the control unit 31 determines that the user 11 is not in the vehicle 12. On the other hand, when a route on which the user will move to the destination using the first means of transportation is being guided, the control unit 31 determines that the user 11 is in the vehicle 12. After that, the control unit 31 ends the determination processing.

As described above, the terminal device 30 has the single-modal guidance function. The single-modal guidance function guides a route on which the user 11 will move, using one of the two means of transportation, either first means of transportation including the vehicle 12 or the second means of transportation not including the vehicle 12, whichever is selected by the user 11. The determining by the terminal device 30 whether the user 11 is in the vehicle 12 includes determining whether the user 11 is in the vehicle 12 according to whether the destination has been set and whether or not the condition (C3) is satisfied that a route on which the user 11 will move to the destination using the second means of transportation is being guided by the single-modal guidance function. In FIG. 8, whether or not C3 is satisfied is determined in step S124.

When the user 11 selects means of transportation other than the vehicle 12, such as walking or a train, and then the guidance of a single-modal route using the selected means of transportation is started, there is a low possibility that, while the single-modal route is being guided, the user 11 will change the means of transportation to the vehicle 12 that is one of the other means of transportation. Taking this into account, even if the user 11 who does not intend to move by the vehicle 12 mistakenly receives the beacon emitted by the vehicle 12, the control unit 31 does not determine that the user 11 is in the vehicle 12. Therefore, this modification prevents an erroneous determination that the user 11 is in the vehicle 12, improving the accuracy in determining whether the user 11 is in the vehicle.

As described above, in this embodiment, the control unit 31 has the multimodal guidance function. The multimodal guidance function is the function that guides a route on which the user 11 will move using a combination of one or more means of transportation selected from among a plurality of types of transportation including the vehicle 12. When the destination has been set and a route on which the user 11 will move to the destination using a combination of means of transportation including the vehicle 12 is being guided by the multimodal guidance function, the control unit 31 determines that the user 11 is in the vehicle 12.

When the guidance of a multimodal route, which uses a combination of means of transportation including the vehicle 12, is started, there is a possibility that the user 11 will change the means of transportation from the means of transportation other than the vehicle 12, such as walking or a train, to the vehicle 12 while the route is being guided. Taking this into account, even if the terminal device 30 of the user 11 to whom a multi-modal route guidance is not being given, that is, who does not intend to move by the vehicle 12, receives the beacon emitted by the vehicle 12, the control unit 31 does not determine that the user 11 is in the vehicle 12. Therefore, this embodiment prevents an erroneous determination that the user 11 is in the vehicle 12, improving the accuracy in determining whether the user 11 is in the vehicle.

As described above, in this embodiment, the control unit 31 determines that the user 11 is not on the vehicle 12 when the destination has been set and, in addition, the user 11 is moving to the destination by another vehicle at the time when the signal sent from the communication device 40 is received.

While the user 11 is in a vehicle other than the vehicle 12, the terminal device 30 may sometimes receive the beacon emitted by the vehicle 12 that happens to be traveling nearby. In such a case, there is a low possibility that the user 11 will change the vehicle from the vehicle, in which the user 11 is travelling, to the vehicle 12 that emits the beacon. Taking this into account, even if the terminal device 30 of the user 11 who does not intend to move by the vehicle 12 receives the beacon emitted by the vehicle 12, the control unit 31 does not determine that the user 11 is in the vehicle 12. Therefore, this embodiment makes it easy to prevent an erroneous determination that the user 11 is in the vehicle 12, improving the accuracy in determining whether the user 11 is in the vehicle.

In one modification of this embodiment, the control unit 31 may determine whether the user 11 is in the vehicle 12 according to whether the vehicle dispatch application, a program for receiving the vehicle dispatch service, is activated in the terminal device 30.

For example, in FIG. 5, when the riding determination processing is performed in step S112 after the beacon is received from the communication device 40, the control unit 31 checks whether the vehicle dispatch application is activated in the terminal device 30. The control unit 31 monitors the activation status of one or more applications running in the terminal device 30 and determines whether the vehicle dispatch application is included in the one or more applications that are activated. The applications that are activated include an application through which the user 11 is performing an input operation and the applications that are activated in the background. The control unit 31 determines that the user 11 is not in the vehicle 12 when the vehicle dispatch application is not activated in the terminal device 30. The control unit 31 determines that the user 11 is in the vehicle 12 when the vehicle dispatch application is activated in the terminal device 30.

According to this modification, there is a high possibility that the user 11 calls a taxi, which is the vehicle 12, by the vehicle dispatch application and uses the vehicle 12. Taking this into account, even if the terminal device 30 of user 11 who does not have the vehicle dispatch application activated, that is, who does not intend to move by the vehicle 12, receives the beacon emitted by the vehicle 12, the control unit 31 does not determine that the user 11 is in the vehicle 12. Therefore, this embodiment makes it easy to prevent an erroneous determination that the user 11 is in the vehicle 12, improving the accuracy in determining whether the user 11 is in the vehicle.

As described above, according to this embodiment, the terminal device 30 further includes the input unit 34 that accepts an input of the set value of a destination from the user 11.

This embodiment improves the convenience for the user 11 to set a destination.

In this embodiment, the communication unit 33 of the terminal device 30 communicates with the control device 20 that notifies the communication device 40, used in the vehicle 12 in which the user 11 is traveling, of the destination set by the user 11. The control unit 31 of the terminal device 30 sends the first data, which notifies about the destination together with the user identifier “U1” corresponding to the user 11, to the control device 20 via the communication unit 33. In response to an operation of the user 11, the control unit 31 acquires the vehicle identifier “V1” corresponding to the vehicle 12. The control unit 31 sends the second data, which notifies about the vehicle identifier “V1” together with the user identifier “U1”, to the control device 20 via the communication unit 33.

Therefore, this embodiment allows the information on the destination, which is set by the user 11, to be used for setting the destination of the vehicle 12 in which the user 11 is travelling.

In this embodiment, when the beacon (signal) is received from the communication device 40, the control unit 31 of the terminal device 30 notifies the user 11 of a message prompting the user 11 to perform the operation of the riding procedure.

Even if the user 11 simply forgets to perform the riding procedure, this embodiment prompts the user to perform the riding procedure by reminding the user that the setting of the destination will be used for the vehicle 12.

The present disclosure is not limited to the above embodiment. For example, a plurality of blocks included in the block diagram may be integrated, or one block may be divided. Instead of performing the steps shown in the flowchart in chronological order according to the description, the steps may be performed in parallel or in a different order depending on the processing capability of the device that performs the steps or depending on the necessity. Other changes may be made without departing from the spirit of the present disclosure.
