Mode for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present disclosure will be described.

[0012] (Outline of the Embodiment) With reference to FIG. 1, the outline of the system 1 according to the embodiment of the present disclosure will be described. The system 1 includes a vehicle 10 and an information processing apparatus 20. The vehicle 10 and the information processing apparatus 20 are communicably connected to a network 30 including, for example, the Internet and a mobile communication network. The number of each of the vehicle 10 and the information processing apparatus 20 included in the system 1 may be arbitrarily determined.

[0013] The vehicle 10 is an automobile including an engine, an alternator, and a battery. For example, automobiles such as gasoline automobiles, hybrid vehicles (HV), or plug-in hybrid vehicles (PHV) can be adopted as the vehicle 10, but the vehicle 10 is not limited thereto.

[0014] In the present embodiment, the vehicle 10 has a function of converting electric power from an alternator or a battery into household electric power and supplying it to an external device (hereinafter, also referred to as "power supply function"). Household electric power is, for example, in Japan, alternating current power with a voltage of 100 V and a frequency of 50 Hz or 60 Hz. However, the voltage and frequency of household electric power are not limited thereto. Alternatively, the household electric power may be direct current power.

[0015] The information processing device 20 is a computer such as a PC (Personal Computer), a smartphone, a tablet terminal, or a server device. The information processing device 20 can communicate with the vehicle 10 via the network 30. The information processing device 20 may be a computer used by an operator such as a manufacturer or a seller of the vehicle 10, or may be a computer used by the owner of the vehicle 10. The vehicle 10 may be pre-registered in the information processing device 20 as an automobile whose owner has approved its use for the purpose of disaster support, for example, providing a power supply function to unspecified disaster victims.

[0016] First, the outline of this embodiment will be described, and the details will be described later. The information processing device 20 acquires vehicle information of the vehicle 10 having a power supply function for supplying power from an alternator or a battery to an external device. The information processing device 20 selects, based on the vehicle information, a first mode that permits the supply of power from the alternator or a second mode that prohibits the supply of power from the alternator as the mode of the power supply function of the vehicle 10. Then, the information processing device 20 transmits an instruction to activate the power supply function in the selected mode to the vehicle 10.

[0017] As described above, according to this embodiment, the power supply function of the vehicle 10 is activated in the first mode or the second mode selected by the information processing device 20. When the power supply function is activated in the first mode in which the supply of power from the alternator is permitted, it is necessary to permit the starting of the engine of the vehicle 10. On the other hand, when the power supply function is activated in the second mode in which the supply of power from the alternator is prohibited, it is not necessary to permit the starting of the engine of the vehicle 10. Therefore, for example, when assuming that the power supply function of the vehicle 10 is activated from a remote location for disaster support and used by unspecified disaster victims, when the power supply function is activated in the first mode, in addition to the battery, power from the alternator can also be supplied to external devices, so the disaster support effect can be improved compared to the second mode. On the other hand, when the power supply function is activated in the second mode, for example, by prohibiting the starting of the engine of the vehicle 10, the possibility of theft of the vehicle 10 by malicious persons can be reduced. Therefore, when activating the power supply function, the technology of supplying power from the vehicle 10 to external devices is improved in that it is possible to select the first mode that can improve the disaster support effect and the second mode that can reduce the possibility of theft of the vehicle 10.

[0018] Next, each component of the system 1 will be described in detail.

[0019] (Configuration of Vehicle) As shown in FIG. 2, the vehicle 10 includes a power supply unit 11, a communication unit 12, a positioning unit 13, a storage unit 14, and a control unit 15.

[0020] The power supply unit 11 includes, for example, a converter that converts power from an alternator or a battery mounted on the vehicle 10 into household power, and a socket into which a dedicated or general-purpose power plug can be inserted. By the vehicle 10 including the power supply unit 11, a power supply function for supplying household power is realized. The power supply function may be activated, for example, when the owner performs a predetermined operation on the vehicle 10. In this embodiment, the power supply function is activated remotely, for example, based on an instruction transmitted from the information processing device 20 to the vehicle 10 during a disaster.

[0021] The communication unit 12 includes one or more communication interfaces for connecting to the network 30. The communication interface corresponds to, for example, mobile communication standards such as 4G (4th Generation) or 5G (5th Generation), but is not limited thereto and may correspond to any communication standard. In the present embodiment, the vehicle 10 communicates with the information processing device 20 via the communication unit 12 and the network 30.

[0022] The positioning unit 13 includes one or more devices for acquiring the position information of the vehicle 10. Specifically, the positioning unit 13 includes, for example, a receiver corresponding to GPS (Global Positioning System), but is not limited thereto and may include a receiver corresponding to any satellite positioning system.

[0023] The storage unit 14 includes one or more memories. The memory is, for example, a semiconductor memory, a magnetic memory, or an optical memory, etc., but is not limited thereto. Each memory included in the storage unit 14 may function as, for example, a main storage device, an auxiliary storage device, or a cache memory. The storage unit 14 stores any information used for the operation of the vehicle 10. For example, the storage unit 14 may store a system program, an application program, and embedded software, etc. The information stored in the storage unit 14 may be updated, for example, with information acquired from the network 30 via the communication unit 12.

[0024] The control unit 15 includes one or more processors, one or more programmable circuits, one or more dedicated circuits, or a combination thereof. The processor is, for example, a general-purpose processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), or a dedicated processor specialized for specific processing, but is not limited thereto. The programmable circuit is, for example, an FPGA (Field-Programmable Gate Array), but is not limited thereto. The dedicated circuit is, for example, an ASIC (Application Specific Integrated Circuit), but is not limited thereto. The control unit 15 may include an ECU (Electronic Control Unit) provided in the vehicle 10. The control unit 15 controls the operation of the entire vehicle 10.

[0025] (Configuration of the information processing device) As shown in FIG. 3, the information processing device 20 includes a communication unit 21, a storage unit 22, and a control unit 23.

[0026] The communication unit 21 includes one or more communication interfaces connected to the network 30. The communication interface corresponds to, for example, a mobile communication standard, a wired LAN (Local Area Network) standard, or a wireless LAN standard, but is not limited thereto and may correspond to any communication standard. In the present embodiment, the information processing device 20 communicates with the vehicle 10 via the communication unit 21 and the network 30. Note that the information processing device 20 may communicate with a vehicle other than the vehicle 10 according to the present embodiment, such as an automobile having no power supply function, via the communication unit 21 and the network 30.

[0027] The storage unit 22 includes one or more memories. Each memory included in the storage unit 22 may function as, for example, a main storage device, an auxiliary storage device, or a cache memory. The storage unit 22 stores any information used for the operation of the information processing apparatus 20. For example, the storage unit 22 may store a system program, an application program, a database, map information, and the like. The information stored in the storage unit 22 may be updated with information acquired from the network 30 via the communication unit 21, for example.

[0028] The control unit 23 includes one or more processors, one or more programmable circuits, one or more dedicated circuits, or a combination thereof. The control unit 23 controls the operation of the entire information processing apparatus 20.

[0029] (Operation flow of the information processing apparatus) With reference to FIG. 4, the operation of the information processing apparatus 20 according to the present embodiment will be described. When the system 1 includes a plurality of vehicles 10, the operations in steps S101 to S107 are executed for each vehicle 10.

[0030] Step S100: The control unit 23 of the information processing apparatus 20 acquires disaster information indicating an area where a disaster has occurred (hereinafter, also referred to as a "disaster area").

[0031] Any method can be adopted to acquire the disaster information. For example, the control unit 23 may directly receive the disaster information from an external server via the communication unit 21 and the network 30, or may acquire the disaster information by estimating the disaster area based on the information acquired via the communication unit 21 and the network 30. For example, the disaster area can be estimated based on a signal from a disaster detection sensor connected to the network 30 or information such as a posted message on an SNS (Social Networking Service) provided via the network 30, but any method can be adopted for estimating the disaster area.

[0032] Step S101: The control unit 23 acquires the vehicle information of the vehicle 10.

[0033] Specifically, the control unit 23 acquires vehicle information from the vehicle 10 via the communication unit 21 and the network 30. The vehicle information includes information indicating the remaining capacity of the battery of the vehicle 10. The remaining capacity of the battery may be estimated by, for example, the control unit 15 of the vehicle 10. For the estimation of the remaining capacity of the battery, any method such as the Coulomb counting method can be adopted. The unit of the remaining capacity of the battery may be, for example, a percentage or an amount of electric power. Further, the vehicle information may include position information indicating the current parking position of the vehicle 10. However, the vehicle information is not limited to these and may include any information regarding the vehicle 10.

[0034] Step S102: The control unit 23 determines whether the parking position of the vehicle 10 indicated in the vehicle information is included in the disaster area. If it is determined that the parking position is included in the disaster area (Step S102 - Yes), the process proceeds to Step S103. On the other hand, if it is determined that the parking position is not included in the disaster area (Step S102 - No), the process ends.

[0035] Step S103: If it is determined in Step S102 that the parking position is included in the disaster area (Step S102 - Yes), the control unit 23 determines whether the remaining capacity of the battery of the vehicle 10 is less than the threshold value. If it is determined that the remaining capacity is less than the threshold value (Step S103 - Yes), the process proceeds to Step S104. On the other hand, if it is determined that the remaining capacity is equal to or greater than the threshold value (Step S103 - No), the process proceeds to Step S106.

[0036] Specifically, the control unit 23 compares the remaining capacity indicated in the received vehicle information with the threshold value. The threshold value may be a predetermined value (for example, 50%), or may be a value determined based on the state of the battery (for example, the degree of deterioration). Typically, the threshold value is determined such that the higher the degree of deterioration of the battery (that is, the more the battery is deteriorated), the larger the threshold value is, but the determination of the threshold value is not limited to this example and any method can be adopted.

[0037] Step S104: When it is determined in step S103 that the remaining capacity is less than the threshold (step S103 - Yes), the control unit 23 selects, as the power supply function mode of the vehicle 10, a first mode that permits the supply of power from the alternator.

[0038] Step S105: The control unit 23 transmits an instruction to activate the power supply function in the first mode selected in step S104 to the vehicle 10 via the communication unit 21 and the network 30. Thereafter, the process on the information processing device 20 side ends.

[0039] When the control unit 15 of the vehicle 10 receives the instruction via the communication unit 12 and the network 30, it activates the power supply function. Specifically, the control unit 15 unlocks a locking mechanism such as a door or a cover so that an unspecified user (e.g., a disaster victim) can access the power outlet of the power supply unit 11, and controls the vehicle 10 so that the power supply function becomes available. Therefore, an unspecified user can open the door or the cover of the vehicle 10 and insert the power plug of a desired external device into the power outlet to receive power supply from the vehicle 10.

[0040] Here, the power supply function is activated in the first mode. "The power supply function is activated in the first mode" means that the vehicle 10 is controlled so that power from both the alternator and the battery of the vehicle 10 can be supplied to an external device. For example, the control unit 15 may control the vehicle 10 to supply power from the battery until the remaining capacity of the battery reaches a predetermined reference value, and start the engine to supply power from the alternator when the remaining capacity decreases to the reference value.

[0041] Specifically, the "instruction to enable the power supply function in the first mode" may include a first instruction to permit the engine to start. In other words, when transmitting an instruction to enable the power supply function, the control unit 23 of the information processing apparatus 20 may explicitly permit the engine of the vehicle 10 to start. Specifically, when the first instruction is included in the instruction received from the information processing apparatus 20 (that is, when the permission to start the engine is explicitly stated), the control unit 15 of the vehicle 10 determines that the received instruction is an instruction to enable the power supply function in the first mode, and enables the power supply function in the first mode.

[0042] Step S106: If it is determined in step S103 that the remaining capacity is equal to or greater than the threshold (step S103 - No), the control unit 23 selects a second mode that prohibits the supply of power from the alternator as the mode of the power supply function of the vehicle 10.

[0043] Step S107: The control unit 23 transmits an instruction to enable the power supply function in the second mode selected in step S106 to the vehicle 10 via the communication unit 21 and the network 30. Thereafter, the process on the information processing apparatus 20 side ends.

[0044] When the control unit 15 of the vehicle 10 receives the instruction via the communication unit 12 and the network 30, it enables the power supply function. Specifically, the control unit 15 unlocks a locking mechanism such as a door or a cover so that an unspecified user (for example, a disaster victim) can access the outlet of the power supply unit 11, and controls the vehicle 10 so that the power supply function becomes available. Therefore, an unspecified user can receive power supply from the vehicle 10 by opening the door or the cover of the vehicle 10 and inserting the power plug of a desired external device into the outlet, in the same manner as in step S105 described above.

[0045] Here, the power supply function is enabled in the second mode. "The power supply function is enabled in the second mode" means that the vehicle 10 is controlled such that power from the battery of the vehicle 10 can be supplied to an external device, while power from the alternator of the vehicle 10 is not supplied to the external device. Specifically, the control unit 15 controls the vehicle 10 so that only power from the battery can be supplied. On the other hand, different from the above-described step S105, the control unit 15 controls the vehicle 10 so as not to supply power from the alternator. For example, the control unit 15 may enable the power supply function in the second mode by controlling the vehicle 10 so that the rotational force of the engine is not transmitted to the wheels and the alternator. In such a case, even if an operation to start the engine is performed by an unspecified user, the vehicle 10 does not move and power generation by the alternator is not performed.

[0046] Specifically, the "instruction to enable the power supply function in the second mode" may include a second instruction to prohibit starting of the engine. In other words, when transmitting an instruction to enable the power supply function, the control unit 23 of the information processing device 20 may explicitly prohibit starting of the engine for the vehicle 10. Specifically, when the second instruction is included in the instruction received from the information processing device 20 by the control unit 15 of the vehicle 10 (that is, when prohibition of starting of the engine is explicitly stated), the control unit 15 determines that the received instruction is an instruction to enable the power supply function in the second mode. Then, after controlling the vehicle 10 to actively prohibit starting of the engine, the control unit 15 enables the power supply function in the second mode. In such a case, the control unit 15 does not start the engine even if an operation to start the engine is performed by an unspecified user.

[0047] Further, the "instruction to activate the power supply function in the second mode" may include a third instruction to fix the shift position of the vehicle 10 to parking. Specifically, when the third instruction is included in the instruction received from the information processing device 20, the control unit 15 of the vehicle 10 determines that the received instruction is an instruction to activate the power supply function in the second mode. Then, after controlling the vehicle 10 to fix the shift position to parking, the control unit 15 activates the power supply function in the second mode. For fixing the shift position, for example, a method of physically fixing the shift lever to the parking position, or a method of outputting a signal indicating parking as the shift position regardless of the actual position of the shift lever may be adopted, but it is not limited to these and any method can be adopted. In such a case, for example, even if an operation to start the engine is performed by an unspecified user, the vehicle 10 does not move.

[0048] Further, the "instruction to activate the power supply function in the second mode" may include a fourth instruction to switch the mode of the power supply function from the second mode to the first mode when the remaining capacity of the battery of the vehicle 10 becomes less than the threshold value. Specifically, when the fourth instruction is included in the instruction received from the information processing device 20, the control unit 15 of the vehicle 10 determines that the received instruction is an instruction to activate the power supply function in the second mode. The control unit 15 activates the power supply function in the second mode and monitors the remaining capacity of the battery. Then, when the remaining capacity of the battery becomes less than the threshold value, the control unit 15 switches the mode of the power supply function from the second mode to the first mode.

[0049] As described above, the information processing device 20 according to the present embodiment acquires vehicle information of the vehicle 10 having a power supply function for supplying power from the alternator or the battery to an external device. The information processing device 20 selects, based on the vehicle information, a first mode that permits the supply of power from the alternator or a second mode that prohibits the supply of power from the alternator as the mode of the power supply function of the vehicle 10. Then, the information processing device 20 transmits an instruction to activate the power supply function in the selected mode to the vehicle 10.

[0050] According to such a configuration, the power supply function of the vehicle 10 is activated in the first mode or the second mode selected by the information processing device 20. When the power supply function is activated in the first mode in which the supply of power from the alternator is permitted, it is necessary to permit the starting of the engine of the vehicle 10. On the other hand, when the power supply function is activated in the second mode in which the supply of power from the alternator is prohibited, it is not necessary to permit the starting of the engine of the vehicle 10. Therefore, for example, when assuming that the power supply function of the vehicle 10 is activated from a remote location for disaster support and used by unspecified disaster victims, when the power supply function is activated in the first mode, in addition to the battery, power from the alternator can also be supplied to external devices, so the disaster support effect can be improved compared to the second mode. On the other hand, when the power supply function is activated in the second mode, for example, by prohibiting the starting of the engine of the vehicle 10, the possibility of theft of the vehicle 10 by malicious persons can be reduced. Therefore, when activating the power supply function, the technology of supplying power from the vehicle 10 to an external device is improved in that it is possible to select the first mode that can improve the disaster support effect and the second mode that can reduce the possibility of theft of the vehicle 10.

[0051] Although the present disclosure has been described based on the drawings and embodiments, it should be noted that those skilled in the art may make various modifications and alterations based on the present disclosure. Therefore, it should be noted that these modifications and alterations are included in the scope of the present disclosure. For example, the functions and the like included in each component or each step, etc. can be rearranged so as not to be logically contradictory, and it is possible to combine a plurality of components or steps, etc. into one or divide them.

[0052] For example, in the above-described embodiment, an embodiment in which the configuration and operation of the information processing device 20 are distributed to a plurality of computers capable of communicating with each other is also possible. Also, for example, an embodiment in which some or all of the components of the information processing device 20 are provided in the vehicle 10 is also possible.

[0053] Further, in the above-described embodiment, after transmitting an instruction to activate the power supply function in the selected mode, when the control unit 23 of the information processing apparatus 20 acquires information indicating the recovery from a disaster in the disaster area, it may transmit an instruction to deactivate the power supply function to the vehicle 10.

[0054] Specifically, the control unit 23 may directly receive information indicating the recovery from a disaster from an external server via, for example, the communication unit 21 and the network 30, or may estimate the recovery from a disaster based on the information acquired via the communication unit 21 and the network 30. For example, the recovery from a disaster can be estimated based on a signal from a disaster detection sensor connected to the network 30 or information such as a posted message on an SNS provided via the network 30, but any method can be adopted for the estimation of the recovery from a disaster. Then, when the control unit 23 acquires information indicating the recovery from a disaster, it transmits an instruction to deactivate the power supply function to the vehicle 10 via the communication unit 21 and the network 30. When the control unit 15 of the vehicle 10 receives the instruction via the communication unit 12 and the network 30, it deactivates the power supply function. Specifically, the control unit 15 locks a locking mechanism such as a door or a cover so that an unspecified user cannot access the outlet of the power supply unit 11, and controls the vehicle 10 so that the use of the power supply function is prohibited. According to such a configuration, for example, even if the disaster has recovered, the probability of inconvenience such as the power supply function of the vehicle 10 being used by an unspecified user is reduced.

[0055] Also, for example, an embodiment in which a general-purpose computer functions as the information processing apparatus 20 according to the above-described embodiment is also possible. Specifically, a program describing the processing contents for realizing each function of the information processing apparatus 20 according to the above-described embodiment is stored in the memory of a general-purpose computer, and the program is read out and executed by a processor. Therefore, the present disclosure can also be realized as a program executable by a processor or a non-transitory computer-readable medium storing the program.
