Effects of the Invention

[0007] The server equipment and other devices described in this disclosure will improve convenience for users receiving power supply vehicles. [Brief explanation of the drawing]

[0008] [Figure 1] This diagram shows an example of a vehicle management system configuration. [Figure 2] This figure shows an example of the operating procedure for the server device, power supply vehicle, and terminal device. [Modes for carrying out the invention]

[0009] The embodiments will be described below with reference to the drawings.

[0010] Figure 1 shows an example of the configuration of a vehicle management system in one embodiment. The vehicle management system 1 has one or more server devices 10, a vehicle to be powered 12, a terminal device 13, and a power supply vehicle 16, which are connected to each other via a network 11 so as to be able to communicate information with each other.

[0011] The server device 10 is, for example, a server computer that belongs to a cloud computing system or other computing system and functions as a server that implements various functions.

[0012] The vehicle to be powered 12 is a passenger car or commercial vehicle equipped with communication and information processing functions, and is connected to the network 11 via a mobile communication network. The vehicle to be powered 12 is powered by the power of an onboard battery 15 and is, for example, an electric vehicle (BEV; Battery Electric Vehicle), a hybrid vehicle (HEV; Hybrid Electric Vehicle), a plug-in hybrid vehicle (PHEV; Plug-in Hybrid Electric Vehicle), etc. In this embodiment, when power is needed, the vehicle to be powered 12 receives power at a power supply station or receives power from a power supply vehicle 16. The vehicle to be powered 12 may be driven by a driver, or its operation may be automated to any level.

[0013] The terminal device 13 is an information processing device equipped with communication functions, used by the user of the powered vehicle 12, and performs various information communication and information processing. The terminal device 13 is, for example, an information processing terminal such as a smartphone, tablet terminal, or personal computer. The terminal device 13 may be configured as part or all of the in-vehicle device 14 installed in the powered vehicle 12.

[0014] The power supply vehicle 16 is a passenger car or commercial vehicle equipped with communication and information processing functions, and is connected to the network 11 via a mobile communication network. The power supply vehicle 16 has the same configuration as the powered vehicle 12, but the battery 15 in the power supply vehicle 16 includes a battery that stores power for supplying power to the powered vehicle 12. The power supply vehicle 16 is, for example, a gasoline car, a fuel cell electric vehicle (FCEV), or a battery electric vehicle (BEV), hybrid electric vehicle (HEV), or plug-in hybrid electric vehicle (PHEV) powered by the power of the onboard battery 15. The power supply vehicle 16 may be driven by a driver, or its operation may be automated to any level.

[0015] Network 11 may be the Internet, for example, but may also include ad-hoc networks, LANs, MANs (Metropolitan Area Networks), other networks, or any combination thereof.

[0016] In this embodiment, the vehicle management system 1 is a system for assisting the power supply vehicle 16 to rush to charge the powered vehicle 12 when the powered vehicle 12 falls into a power-depleted state. A power-depleted state is a state in which the battery level falls below a certain level. This certain level may be a level set arbitrarily in advance, or it may be a level derived in advance through experiments or the like that is such that one or more operations, including motor driving of the power supply vehicle 16, cannot be performed. Alternatively, a power-depleted state may be a state in which the user of the powered vehicle 12 arbitrarily decides that power supply is necessary. Rush charging is a method of supplying power by having the power supply vehicle 16 move to the location of the powered vehicle 12 and charging the battery 15 of the powered vehicle 12 from the battery 15 of the power supply vehicle 16. In the vehicle management system 1, the server device 10 performs rush charging by executing a process to dispatch the power supply vehicle 16 to each of the one or more powered vehicles 12.

[0017] The server device 10 includes a communication unit 101 and a control unit 103 that communicates via the communication unit 101. The control unit 103 predicts the location and time when the battery level of the vehicle to be powered 12 will reach a predetermined state, i.e., a power-out state, based on the user's travel plans and the battery level of the vehicle to be powered 12 (hereinafter, the predicted location and time will be referred to as the predicted location and predicted time, respectively), and sends information to the user's terminal device 13 proposing the dispatch of a power supply vehicle 16 to the predicted location at the predicted time, prompting the user to decide on the dispatch. If the user wishes to have the power supply vehicle 16 dispatched, the terminal device 13 can send an instruction to the server device 10 to decide on the dispatch, so it is possible to create a plan in advance to receive power at the predicted time and location. Therefore, the user does not need to pay attention to the timing of receiving power while traveling in the vehicle to be powered 12. Thus, user convenience can be improved.

[0018] Next, an example configuration of the server device 10, the powered vehicle 12, and the terminal device 13 will be described.

Alternatively, each part may be communicably connected via an in-vehicle network conforming to a standard such as CAN (Controller Area Network). The battery 15 is, for example, one or more lithium-ion batteries that charge and discharge electric power for driving the power-receiving vehicle 12.

[0030] The output unit 126 includes one or more output interfaces. The output interfaces are, for example, a display or a speaker. The display is, for example, an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) display. The output unit 126 outputs information obtained by the operation of the control unit 123.

[0031] The detection unit 127 has an interface with one or more sensors that detect the state of various parts of the powered vehicle 12, or it has one or more sensors. The sensors include, for example, a sensor that detects the remaining battery level of the battery 15, and a sensor that detects the motion state of the powered vehicle 12 (speed, longitudinal acceleration, lateral acceleration, deceleration, etc.). The detection unit 127 sends information indicating each state detected by the sensors to the control unit 123.

[0032] The functions of the control unit 123 are realized by executing a control program on the processor included in the control unit 123.

In other words, the control program is a program that causes the computer to function as the control unit 123. Furthermore, some or all of the functions of the control unit 123 may be realized by dedicated circuits included in the control unit 123.

[0033] The power supply vehicle 16 has the same configuration as the powered vehicle 12, and the above-described explanation of each part of the powered vehicle 12 applies to the power supply vehicle 16. However, the battery 15 of the power supply vehicle 16 is It includes a battery that charges and discharges power to supply power to the vehicle 12 to be powered.

[0034] The terminal device 13 is, for example, an information processing device such as a smartphone or tablet terminal, or an information processing device that constitutes part or all of an in-vehicle device mounted on the vehicle to be powered 12. The terminal device 13 has a communication unit 131, a storage unit 132, a control unit 133, a positioning unit 134, an input unit 135, and an output unit 136.

The storage unit 132 stores information used in the operation of the control unit 133 and information obtained by the operation of the control unit 133.

[0037] The control unit 133 has, for example, one or more general-purpose processors such as a CPU or MPU (Micro Processing Unit), or one or more dedicated processors specialized for a specific process. Alternatively, the control unit 133 may have one or more dedicated circuits such as FPGAs or ASICs. The control unit 133 comprehensively controls the operation of the terminal device 13 by operating according to a control and processing program, or by operating according to an operating procedure implemented as a circuit.

In addition, some or all of the functions of the control unit 133 may be realized by dedicated circuits included in the control unit 133.

[0042] Figure 2 is a sequence diagram showing an example of the procedure for the coordinated operation of the server device 10, the powered vehicle 12, the terminal device 13, and the power supply vehicle 16. In Figure 2, the steps related to various information processing of the server device 10, the powered vehicle 12, the terminal device 13, and the power supply vehicle 16 are executed by their respective control units 103, 123, 133, and 123. Furthermore, the steps related to the sending and receiving of various information of the server device 10, the powered vehicle 12, the terminal device 13, and the power supply vehicle 16 are executed by the respective control units 103, 123, 133, and 123 sending and receiving information to each other via the communication units 101, 121, 131, and 121. In the server device 10, the powered vehicle 12, the terminal device 13, and the power supply vehicle 16, the control units 103, 123, 133, and 123 respectively store the information to be processed and sent and received in the storage units 102, 122, 132, and 122 as appropriate.

[0043] The procedure shown in Figure 2 is an example of the procedure when the server device 10 dispatches a power supply vehicle 16 to charge the vehicle to be powered 12.

[0044] In step S201, the terminal device 13 sends schedule information to the server device 10. The schedule information includes the user's identification information and the user's travel schedule. The travel schedule includes the destination location and arrival time, the duration of stay at the destination, etc. The terminal device 13 sends the schedule information entered by the user into an application program for schedule management to the server device 10 at an arbitrary frequency. The frequency of sending schedule information may be, for example, every few minutes to every few hours, or each time the schedule is entered or updated. Alternatively, the server device 10 may request the terminal device 13 to send schedule information at an arbitrary interval, and the terminal device 13 may send the schedule information in response. The user can set the frequency of sending schedule information in advance with the terminal device 13.

[0045] In step S202, the server device 10 acquires identification information, location information, and battery information from one or more powered vehicles 12. The server device 10 requests the respective information from one or more powered vehicles 12 and acquires the information sent from each powered vehicle 12 in response to the request. The identification information identifies the powered vehicle 12 and includes information that identifies the user of the powered vehicle 12. This identification information links the user of the terminal device 13 with the powered vehicle 12. The identification information also includes information such as the power required for the powered vehicle 12 to run and the charge / discharge performance of the battery 15. The battery information includes information about the remaining charge of the battery 15. The remaining charge of the battery 15 is, for example, the SOC (State of Charge) value. Step S202 is executed at any frequency, such as every few seconds to tens of seconds, or each time step S201 is executed.

[0046] When the server device 10 receives information from multiple powered vehicles 12, it executes the procedures from step S203 onwards for each powered vehicle 12.

[0047] In step S203, the server device 10 predicts the predicted time and location at which the vehicle to be powered 12 will run out of power. Based on the user's travel plans, the server device 10 derives a travel route and predicts the predicted time and location at which the battery level will run out, based on the power consumed by the vehicle to be powered 12 as it travels along the travel route. The server device 10 derives a travel route from the current location of the vehicle to be powered 12 to the destination included in the travel plans using an arbitrary algorithm. The server device 10 also predicts the change in the battery level of the battery 15 along the travel route based on the power required for the vehicle to be powered 12 to run, the charge / discharge performance of the battery 15, and the distance of the travel route, and determines whether the vehicle to be powered 12 will run out of power at the destination. A run-out state is, for example, a state where the State of Charge (SOC) value of the battery 15 falls below an arbitrary standard. An arbitrary standard is, for example, 20% to 30%. The arbitrary standard may be set in advance by the user in the terminal device 13 and notified to the server device 10. If the vehicle 12 to be powered runs out of power at its destination, the destination is predicted as the predicted point, and the estimated arrival time is predicted as the predicted time. Alternatively, if the vehicle 12 to be powered runs out of power before reaching its destination, the point and time on the travel route where the vehicle is expected to run out of power are predicted as the predicted point and predicted time.

[0048] In step S204, the server device 10 searches for events that will take place near the predicted location at the predicted time. The area near the predicted location is an arbitrary distance including the predicted location. This arbitrary distance could be, for example, several hundred meters to several kilometers. Events that will take place at the predicted time include events that will take place a few minutes to 10 minutes before or after the predicted time. Events can include experiential attractions, sales at shops, etc., and should be of a nature that allows users to spend time on them for a certain period of time. Information on such events is obtained from servers operated by event operators, etc.

[0049] In step S205, the server device 10 sends dispatch proposal information and event information to the user's terminal device 13. The dispatch proposal information is information for proposing the dispatch of a power supply vehicle 12 to perform charging at the predicted location at the predicted time. The dispatch proposal information includes the predicted location and time, and may also include the predicted SOC value in the power-depleted state. The event information includes the type of event searched, an overview of the event, and information on the location and time at which the event will take place.

[0050] In step S206, the terminal device 13 receives the user's dispatch decision. The terminal device 13 outputs the dispatch proposal information received from the server device 10 by displaying it, prompting the user to make a dispatch decision. The terminal device 13 can also output event information received from the server device 10 by displaying it, etc., and present it to the user. Upon receiving the dispatch proposal information, the user can recognize the need for power supply at the predicted location at the predicted time. The user can also recognize the type and outline of events that will take place near the predicted location at the predicted time. By participating in the event during the time required for power supply, the user can make effective use of their time. Therefore, the user can decide whether or not to accept the dispatch of the power supply vehicle 12 by referring to the event information. When the user makes an input indicating a dispatch decision in response to the dispatch proposal, the terminal device 13 receives it. If the user chooses to participate in the event, the user inputs the dispatch decision along with information indicating participation in the event to the terminal device 13.

[0051] In step S207, terminal device 13 sends a dispatch request to server device 10. The dispatch request is a request for the dispatch of a power supply vehicle 12 to receive on-the-spot charging at a predicted time at a predicted location. If the user chooses to participate in the event, the predicted location is replaced with the location where the event is being held. Alternatively, if the dispatch is refused, terminal device 13 may send information to server device 10 indicating that the power supply has been refused.

[0052] The user of terminal device 13 travels in a powered vehicle 12 to the destination of this facility or the location where the event is being held.

[0053] In step S208, the server device 10 updates the schedule information. If the destination is a predicted location and power supply is requested at the predicted location, the server device 10 adds information to the schedule information indicating that power supply will be performed at the predicted location at the predicted time. Alternatively, if a predicted location other than the destination, i.e., the location where the event will take place, is a predicted location and power supply is requested at the predicted location, the server device 10 changes the destination to the location where the event will take place and adds information to the schedule information indicating that power supply will be performed at the predicted location at the predicted time.

[0054] In step S209, the server device 10 creates a dispatch plan. The dispatch plan includes information such as the identification of the power supply vehicle 16 to perform on-site charging, the travel route of the power supply vehicle 16, and the start time of travel. In order to create a power supply plan, the server device 10 obtains location information of one or more power supply vehicles 16 and battery level information of the battery 15. For example, the server device 10 requests one or more power supply vehicles 16 to transmit this information and receives the information sent by the power supply vehicles 16 in response to the request. For example, the server device 10 identifies the power supply vehicle 16 with the largest battery level among the power supply vehicles 16 located within an arbitrary distance range (e.g., several kilometers) from the predicted point as the power supply vehicle 16 to perform on-site charging. Alternatively, the server device 10 identifies the power supply vehicle 16 closest to the predicted point among the power supply vehicles 16 with a battery level of 60% or more above an arbitrary standard (e.g., 60% of the SOC value) as the power supply vehicle 16 to perform on-site charging. The server device 10 then uses an arbitrary algorithm to derive a travel route and a travel start time that will allow the identified power supply vehicle 16 to reach the predicted location by the predicted time.

[0055] In step S210, the server device 10 sends a dispatch instruction to the identified power supply vehicle 16. The dispatch instruction includes information on the travel route to the predicted location and the start time of travel.

[0056] In step S211, the power supply vehicle 16 is dispatched in response to the dispatch order. When the start time for movement arrives, the power supply vehicle 16 begins moving according to the travel route. Alternatively, the vehicle to be powered 12 displays the travel route to the occupants and begins moving in response to the occupants' operations.

[0057] When the power supply vehicle 16 arrives at the predicted location, in step S212, power is supplied from the power supply vehicle 16 to the vehicle to be powered 12. For example, the power supply vehicle 16 charges the battery 15 of the vehicle to be powered 12 with power for power supply from the battery 15, either through the operation of the occupant or the operation of an automated machine.

[0058] While power is being supplied from the power supply vehicle 16 to the powered vehicle 12, the user can, for example, participate in an event, making effective use of their time.

[0059] As described above, users can avoid the hassle of constantly considering the need for power supply while on the move. At the same time, they can make effective use of the time when power is available. Therefore, user convenience can be improved.

[0060] As described above, embodiments have been explained based on various drawings and examples, but it should be noted that those skilled in the art will find it easy to make various modifications and alterations based on this disclosure. Therefore, it should be noted that these modifications and alterations are within the scope of this disclosure.
