[0024] Hereinafter, the embodiment will be specifically described with reference to the drawings.

[0025] The embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components that are not described in an independent claim showing a top concept are described as optional components.

[0026] (Embodiment) [1. Overview of the traffic management system] First, an overview of a traffic control system 2 according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a conceptual diagram showing an overview of a traffic control system 2 according to an embodiment.

[0027] As shown in Fig. 1, a traffic management system 2 according to the embodiment is a system for managing the operation of an electric vehicle 4. The traffic management system 2 includes an adapter 6, a mobile terminal 8, an in-vehicle device 10, and a server 12. For convenience of explanation, Fig. 1 shows only one electric vehicle 4, but in reality, the traffic management system 2 manages the operations of a plurality of electric vehicles 4 in an integrated manner.

[0028] The electric vehicle 4 is, for example, a passenger car or truck for business use owned by a delivery company. The electric vehicle 4 has a battery 14, a motor 16, a motor drive unit 18, and a charging circuit 20. The battery 14 is a secondary battery that can be repeatedly charged. The motor 16 is a prime mover for propelling the electric vehicle 4. The motor drive unit 18 drives the motor 16 with power stored in the battery 14 in response to driving operations by the driver. The charging circuit 20 is electrically connected to a charging facility 24 via a charging cable 22, and charges the battery 14 with power supplied from the charging facility 24.

[0029] The electric vehicle 4 may be an EV (Electric Vehicle) that runs only on the motor 16, or a Plug-In Hybrid Electric Vehicle (PHEV) that runs using both the motor 16 and an engine (not shown). Furthermore, the electric vehicle 4 is not limited to a four-wheel electric vehicle, and may be a two- or three-wheel electric vehicle.

[0030] A connector 26 and a plug 28 are disposed on both ends of the charging cable 22. The connector 26 is detachably and electrically connected to the charging circuit 20 via a charging port 30 of the electric vehicle 4. The plug 28 is detachably and electrically connected to the charging equipment 24. The charging equipment 24 is, for example, an outdoor outlet.

[0031] In this embodiment, the charging facility 24 is an outdoor outlet, but is not limited thereto, and the charging facility 24 may be, for example, a charger installed at a charging spot. In this case, a charging cable can be pulled out from the charger, and a connector is provided at the tip of the charging cable.

[0032] The adapter 6 is detachably and electrically connected to the plug 28 of the charging cable 22. That is, the plug 28 of the charging cable 22 is detachably and electrically connected to the charging equipment 24 via the adapter 6.

[0033] Although not shown, when the charging equipment 24 is a charger installed at a charging spot, the adapter 6 is detachably and electrically connected to a connector of a charging cable pulled out from the charger. In this case, the connector of the charging cable is, for example, a CHAdeMO (registered trademark) standard connector, and is electrically connected to the charging port 30 of the electric vehicle 4 via the adapter 6.

[0034] The adapter 6 has a measurement function for measuring the amount of charging energy and a communication function for wirelessly transmitting charging energy amount information relating to the amount of charging energy to the outside. That is, the adapter 6 measures (acquires) the amount of charging energy of the battery 14 while the battery 14 of the electric vehicle 4 is being charged with power from the charging facility 24. After charging of the battery 14 is completed, the adapter 6 transmits the charging energy amount information to the mobile terminal 8 by short-range wireless communication such as Bluetooth (registered trademark). The charging energy amount information includes information indicating the amount of charging energy measured by the adapter 6 and information indicating the date and time when the battery 14 of the electric vehicle 4 was charged.

[0035] The mobile terminal 8 is, for example, a smartphone or a tablet terminal owned by a user (for example, a driver of the electric vehicle 4). The mobile terminal 8 is capable of communicating with the adapter 6 through short-range wireless communication. The mobile terminal 8 is also capable of communicating with the server 12 through a network 32 such as the Internet. The mobile terminal 8 receives charging energy information from the adapter 6 through short-range wireless communication, and transfers the received charging energy information to the server 12 through the network 32. That is, the adapter 6 transmits the charging energy information to the server 12 through the mobile terminal 8.

[0036] The vehicle-mounted device 10 is mounted on the electric vehicle 4 and is, for example, an in-vehicle device conforming to ETC (Electric Toll Collection System) 2.0. The vehicle-mounted device 10 acquires location information indicating the current location of the electric vehicle 4 by a GPS (Global Positioning System) every time the electric vehicle 4 travels a predetermined distance (for example, 200 m). That is, the vehicle-mounted device 10 acquires location information at predetermined distance intervals (for example, 200 m intervals) as travel history information (probe data) relating to the travel history of the electric vehicle 4. In addition, when the electric vehicle 4 travels near an ITS (Intelligent Transport Systems) spot 34 installed on a road, the vehicle-mounted device 10 transmits the travel history information to the ITS spot 34.

[0037] The ITS spot 34 can communicate with a management server 35 managed by the Ministry of Land, Infrastructure, Transport and Tourism via the ITS spot network 36. The ITS spot 34 receives driving history information from the vehicle-mounted device 10, and transmits the received driving history information to the management server 35 via the ITS spot network 36. The management server 35 is a server for managing driving history information, and only businesses that have been authorized in advance by the Ministry of Land, Infrastructure, Transport and Tourism can communicate with the server 12 via the network 32.

[0038] The server 12 is, for example, a cloud server. The server 12 receives charging energy information from the mobile terminal 8 and driving history information from the management server 35 via the network 32. The server 12 estimates a cruising distance of the electric vehicle 4 based on the received charging energy information and driving history information. The server 12 also causes the display unit 38 to display information indicating the estimated cruising distance (estimation result) via the network 32.

[0039] The display unit 38 is, for example, a display of a terminal device 40 installed in a delivery company. The terminal device 40 may be, for example, a personal computer, a smartphone, a tablet terminal, or the like.

[0040] [2. Functional configuration of the traffic management system] Next, a functional configuration of the traffic control system 2 according to the embodiment will be described with reference to Fig. 2. Fig. 2 is a block diagram showing the functional configuration of the traffic control system 2 according to the embodiment.

[0041] 2, the adapter 6 has, as its functional configuration, a measurement unit 42 (an example of a first acquisition unit) and a communication unit 44 (an example of a first transmission unit). The measurement unit 42 measures (acquires) the amount of charging energy of the battery 14 while the battery 14 of the electric vehicle 4 is being charged with power from the charging facility 24. After charging of the battery 14 is completed, the communication unit 44 transmits charging energy information measured by the measurement unit 42 to the mobile terminal 8 via short-range wireless communication.

[0042] The mobile terminal 8 has an operation unit 46 and a communication unit 48 as functional configurations. The operation unit 46 accepts user operations. Specifically, the operation unit 46 accepts input of initial setting information such as the maximum charging capacity and initial remaining charge of the battery 14 by the user. Here, the maximum charging capacity is the maximum amount of power that can be charged to the battery 14, and the initial remaining charge is the remaining charge (SOC: State Of Charge) of the battery 14 in an initial state before charging the battery 14. The communication unit 48 receives charging energy information from the adapter 6 by short-range wireless communication, and transfers the received charging energy information to the server 12 via the network 32 (see FIG. 1). That is, the communication unit 44 of the adapter 6 transmits the charging energy information to the server 12 via the mobile terminal 8. In addition, the communication unit 48 transmits the initial setting information received by the operation unit 46 to the server 12 via the network 32.

[0043] The vehicle-mounted device 10 has, as its functional configuration, a positioning unit 50 (an example of a second acquisition unit) and a communication unit 52 (an example of a second transmission unit). The positioning unit 50 acquires position information indicating the current position of the electric vehicle 4 by GPS every time the electric vehicle 4 travels a predetermined distance (e.g., 200 m). That is, the positioning unit 50 acquires position information at predetermined distance intervals (e.g., 200 m intervals) as travel history information related to the travel history of the electric vehicle 4. The communication unit 52 transmits the travel history information acquired by the positioning unit 50 to the ITS spot 34 when the electric vehicle 4 travels near the ITS spot 34 installed on the road.

[0044] The ITS spot 34 receives the driving history information from the vehicle-mounted device 10, and transmits the received driving history information to the management server 35 via an ITS spot network 36 (see FIG. 1).

[0045] The management server 35 receives the driving history information from the ITS spot 34 and stores the received driving history information in a memory. The management server 35 also transmits the driving history information stored in the memory to the server 12 via the network 32.

[0046] The server 12 has, as functional components, a communication unit 54, an estimation unit 56, and a display control unit 58. The communication unit 54 receives charging energy information and initial setting information from the mobile terminal 8, and driving history information from the management server 35, via the network 32.

[0047] The estimation unit 56 acquires the charging energy information and the driving history information from the communication unit 54, and estimates the cruising distance of the electric vehicle 4 based on the acquired charging energy information and driving history information. Specifically, the estimation unit 56 calculates the electricity consumption (electricity consumption rate) of the electric vehicle 4 based on the maximum charging capacity and the initial remaining charge included in the initial setting information, and the accumulated charging capacity and accumulated driving distance calculated from the charging energy information and the driving history information. The estimation unit 56 then estimates the cruising distance of the electric vehicle 4 based on the calculated electricity consumption and the current remaining charge calculated from the initial remaining charge and the charging energy information. The cruising distance here is the distance that the electric vehicle 4 can travel from its current location until the current remaining charge is used up.

[0048] The display control unit 58 transmits information indicating the cruising distance (estimation result) estimated by the estimation unit 56 to the terminal device 40 via the network 32. That is, the display control unit 58 causes the display unit 38 of the terminal device 40 to display the information indicating the cruising distance estimated by the estimation unit 56 via the network 32.

[0049] [3. Operation of the Traffic Control System] Next, the operation of the traffic control system 2 according to the embodiment will be described with reference to Fig. 3. Fig. 3 is a sequence diagram showing the flow of the operation of the traffic control system 2 according to the embodiment.

[0050] As shown in FIG. 3, first, the measurement unit 42 of the adapter 6 measures the amount of charging power in the battery 14 while the battery 14 of the electric vehicle 4 is being charged with power from the charging facility 24 (S101).

[0051] Next, after charging of the battery 14 is completed, the communication unit 44 of the adapter 6 transmits the charging energy information measured by the measurement unit 42 to the mobile terminal 8 (S102). Next, the mobile terminal 8 transmits (transfers) the received charging energy information to the server 12 (S103).

[0052] Next, the communication unit 54 of the server 12 receives the charging energy information from the mobile terminal 8 (S104).

[0053] Next, the positioning unit 50 of the vehicle-mounted device 10 acquires position information indicating the current position of the electric vehicle 4 by GPS every time the electric vehicle 4 travels a predetermined distance (e.g., 200 m). That is, the positioning unit 50 acquires position information at predetermined distance intervals (e.g., 200 m intervals) as travel history information related to the travel history of the electric vehicle 4 (S105).

[0054] Next, the communication unit 52 of the vehicle-mounted device 10 transmits the driving history information acquired by the positioning unit 50 to the management server 35 via the ITS spot 34 (S106). Next, the management server 35 receives the driving history information from the vehicle-mounted device 10 (S107) and transmits the received driving history information to the server 12 (S108).

[0055] Next, the communication unit 54 of the server 12 receives the driving history information from the management server 35 (S109). Next, the estimation unit 56 of the server 12 acquires the charging energy information and the driving history information from the communication unit 54, and estimates the cruising distance of the electric vehicle 4 based on the acquired charging energy information and driving history information (S110).

[0056] Next, the display control unit 58 of the server 12 transmits information indicating the cruising distance estimated by the estimation unit 56 to the terminal device 40 via the network 32 (S111). As a result, the display unit 38 of the terminal device 40 displays the information indicating the cruising distance estimated by the estimation unit 56 of the server 12 (S112).

[0057] Here, an example of the display content of the display unit 38 of the terminal device 40 will be described with reference to Fig. 4. Fig. 4 is a diagram showing an example of the display content of the display unit 38 of the terminal device 40 according to the embodiment.

[0058] 4, the display unit 38 of the terminal device 40 displays a map 60 of the area in which the electric vehicle 4 is currently traveling, a dotted line 62 indicating the travel path of the electric vehicle 4, a triangular mark 64 indicating the current position of the electric vehicle 4, a circle 66 centered on the current position of the electric vehicle 4 and having a radius equal to the cruising distance estimated by the estimation unit 56, and a star-shaped mark 68 indicating the position of a charging spot where the electric vehicle 4 can be charged. That is, the circle 66 indicates the range of the cruising distance from the current position of the electric vehicle 4. Note that the mark 64 does not necessarily need to indicate the exact current position of the electric vehicle 4, and may indicate the position of the ITS spot 34 closest to the current position of the electric vehicle 4.

[0059] An operator of the delivery company or the like can ascertain the cruising distance of the electric vehicle 4 by looking at the circle 66 displayed on the display unit 38. This allows, for example, the operator of the delivery company or the like to wirelessly notify the driver of the electric vehicle 4 of nearby charging spots that can be reached from the current location before the current remaining charge is used up (i.e., charging spots corresponding to the marks 68 inside the circle 66).

[0060] Hereinafter, other examples of the display contents of the display unit 38 of the terminal device 40 will be described with reference to Fig. 5 to Fig. 7. Fig. 5 to Fig. 7 are diagrams showing other examples of the display contents of the display unit 38 of the terminal device 40 according to the embodiment.

[0061] 5, the display unit 38 of the terminal device 40 displays a map 60 of the area in which the electric vehicle 4 is currently traveling, a dotted line 62 indicating the travel path of the electric vehicle 4, a dotted line 63 indicating the planned travel route of the electric vehicle 4, a triangular mark 64 indicating the current position of the electric vehicle 4, a circle 70 centered on the destination of the electric vehicle 4 and with a radius of the cruising distance estimated by the estimation unit 56, and a star-shaped mark 68 indicating the position of a charging spot where the electric vehicle 4 can be charged. In other words, the circle 66 indicates the range of the cruising distance from the destination of the electric vehicle 4.

[0062] In the example shown in Fig. 5, the estimation unit 56 of the server 12 calculates the amount of power consumption until the electric vehicle 4 reaches the destination based on the electricity consumption and the distance traveled from the current position of the electric vehicle 4 to the destination. The estimation unit 56 then calculates the predicted remaining charge, which is the remaining charge at the time the electric vehicle 4 reaches the destination, by subtracting the calculated amount of power consumption from the current remaining charge. The estimation unit 56 then estimates the cruising distance of the electric vehicle 4 based on the electricity consumption and the calculated predicted remaining charge. The cruising distance here is the distance that the electric vehicle 4 can travel from the destination until the predicted remaining charge is used up.

[0063] An operator of the delivery company or the like can ascertain the cruising distance of the electric vehicle 4 by looking at the circle 70 displayed on the display unit 38. This allows, for example, the operator of the delivery company or the like to wirelessly notify the driver of the electric vehicle 4 of a charging spot that can be reached from the destination before the predicted remaining charge is used up (i.e., a charging spot corresponding to the mark 68 inside the circle 70).

[0064] 6, the display unit 38 of the terminal device 40 displays a map 60 of the area in which the electric vehicle 4 is currently traveling, a dotted line 62 indicating the traveling trajectory of the electric vehicle 4, a dotted line 63 indicating the planned traveling route of the electric vehicle 4, a triangular mark 64 indicating the current position of the electric vehicle 4, and star-shaped marks 68a and 68b indicating the positions of charging spots where the electric vehicle 4 can be charged. The mark 68a indicates the position of a charging spot that is relatively close to the planned traveling route of the electric vehicle 4, and is highlighted with, for example, a dark color. On the other hand, the mark 68b indicates the position of a charging spot that is relatively far from the planned traveling route of the electric vehicle 4, and is displayed with, for example, a light color.

[0065] As a result, for example, an operator of a delivery company can wirelessly notify the driver of the electric vehicle 4 of the nearest charging spot from the planned driving route of the electric vehicle 4 by looking at the highlighted mark 68a displayed on the display unit 38.

[0066] In the example shown in FIG. 7, the display unit 38 of the terminal device 40 displays a map 60 of the area in which the electric vehicle 4 is currently traveling, a dotted line 62 indicating the traveling trajectory of the electric vehicle 4, a dotted line 63 indicating the planned traveling route of the electric vehicle 4, a triangular mark 64 indicating the current position of the electric vehicle 4, star-shaped marks 68a and 68b indicating the positions of charging spots where the electric vehicle 4 can be charged, and a message box 72. Note that the mark 68a is assumed to be located at the destination of the electric vehicle 4. In other words, after arriving at the destination, the electric vehicle 4 can be charged at the charging spot at the destination. The message box 72 displays a message such as "Please charge for 2 hours after arriving at the destination" or "Please charge 20 kWh after arriving at the destination" to notify the time required for the electric vehicle 4 to be charged at the charging spot at the destination.

[0067] 7, the estimation unit 56 of the server 12 calculates the time required for the electric vehicle 4 to charge at the charging spot at the destination (e.g., 12 kWh÷6 kW=2 hours) based on the amount of charging power (e.g., 12 kWh) required for the electric vehicle 4 to return from the destination to the departure point and the output (e.g., 6 kW) of the charger at the charging spot at the destination. Then, the display control unit 58 of the server 12 generates a message box 72 based on the time estimated by the estimation unit 56.

[0068] As a result, for example, an operator of a delivery company can look at the message box 72 displayed on the display unit 38 and predict the time until the electric vehicle 4 returns to the departure point.

[0069] [4. Effects] In this embodiment, the estimation unit 56 of the server 12 estimates the cruising distance of the electric vehicle 4 based on the charging energy information and the driving history information, and the display control unit 58 of the server 12 causes the estimation result of the estimation unit 56 to be displayed on the display unit 38. As a result, for example, in the case where a delivery company or the like owns multiple electric vehicles 4, the delivery company or the like can grasp the cruising distance of each of the multiple electric vehicles 4 and can centrally manage the operation of the multiple electric vehicles 4.

In this case, a SIM (Subscriber Identity Module) card may be mounted in the adapter 6.

[0072] In addition, in the above embodiment, the vehicle-mounted device 10 that complies with ETC 2.0 transmits driving history information to the management server 35, but this is not limited to this, and various types of vehicle-mounted devices other than the vehicle-mounted device 10 may transmit driving history information to the management server 35.
