Description

[Technical Field]

[0001] The present disclosure relates to a disaster response system, a vehicle, and a control method, and in particular to a disaster response system including a vehicle that can be supplied with an energy source from an external source and a server that can communicate with the vehicle and transmits disaster information, a vehicle that can be supplied with an energy source from an external source, and a control method executed in a vehicle that can be supplied with an energy source from an external source. [Background technology]

[0002] Conventionally, when a vehicle such as a plug-in hybrid electric vehicle (PHEV) or a battery electric vehicle (BEV) is connected to a home energy management system (HEMS), charging of the vehicle is initiated when the HEMS receives an emergency disaster alert (see, for example, Patent Document 1). For example, the vehicle's storage battery is charged using grid power or natural energy. This makes it possible to use the power stored in the vehicle's storage battery after a disaster occurs.

[0003] Furthermore, after a disaster occurs, the HEMS switches to available power depending on the severity of the disaster. Specifically, if grid power is unavailable, the HEMS switches the power source from grid power to an available power source (for example, natural energy or a vehicle battery). This allows for a continuous supply of power to a home equipped with the HEMS. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-009488 Summary of the Invention [Problem to be solved by the invention]

[0005] In the event of a disaster, it is expected that people will use vehicles to evacuate. Even if the vehicle's battery is fully charged, the shorter the vehicle's driving time becomes, the greater the anxiety of disaster victims.

[0006] This disclosure has been made to solve such problems, and its purpose is to provide a disaster response system, a vehicle, and a control method that can reduce the user's sense of anxiety. [Means for solving the problem]

[0007] The disaster response system according to the present disclosure includes a vehicle that can receive an energy source from an external source and a server that can communicate with the vehicle and transmits disaster information. The vehicle includes a storage device that can store the energy source, equipment that operates using the energy source of the storage device, a control device, and a communication device that communicates with external devices. The control device controls the equipment to save energy when disaster information is received from the server by the communication device.

[0008] With this configuration, when disaster information is received from the server in the vehicle, the devices that operate on the energy source of the storage device are controlled to save energy. This allows the vehicle's devices to operate for a longer period of time in the event of a disaster. As a result, a disaster response system can be provided that can reduce user anxiety.

[0009] According to another aspect of the present disclosure, a vehicle is a vehicle capable of receiving an energy source from an external source, and includes a storage device capable of storing the energy source, a device that operates using the energy source of the storage device, a control device, and a communication device for communicating with a server that transmits disaster information. The control device controls the device to save energy when the communication device receives the disaster information from the server.

[0010] With this configuration, it is possible to provide a vehicle that can reduce the sense of anxiety felt by the user.

[0011] The control device may perform energy-saving control of the device on the additional condition that the current location of the vehicle is included in the area covered by the disaster information.

[0012] With this configuration, if the vehicle is included in the area affected by the disaster information, the time that the vehicle's equipment can operate can be extended when the user feels more anxious than when the vehicle is not included in the area affected by the disaster information.

[0013] The control device may cancel the energy saving control when a condition for canceling the energy saving control is met.

[0014] With this configuration, when energy saving control is no longer necessary, it is possible to return to normal control, which is not energy saving control.

[0015] The control device may use the energy source currently stored in the storage device to perform energy-saving control of the equipment without performing energy-saving control, with the additional condition that there is no available energy source supply facility within the range where the vehicle will be unable to travel.

[0016] With this configuration, the energy source currently stored in the storage device is used without energy-saving control, and if there is an energy supply facility available within the range where the vehicle cannot travel, the device will not be subjected to energy-saving control. Therefore, even if a disaster occurs, if the vehicle can reach the energy supply facility, the vehicle can travel without energy-saving control. As a result, in situations where the user does not feel anxious, normal control, not energy-saving control, can be used.

[0017] The vehicle may further include an alarm device, and the control device may control the alarm device to alarm information about an available energy source supply facility within a range where the vehicle becomes unable to travel using the energy source currently stored in the storage device without performing energy saving control.

[0018] According to this configuration, if there is a supply facility that can be reached even in the event of a disaster, information about that supply facility is notified to the user, thereby reducing the user's sense of anxiety.

[0019] According to yet another aspect of the present disclosure, there is provided a control method executed in a vehicle capable of receiving an external energy source. The vehicle includes a storage device capable of storing the energy source, a device operating on the energy source of the storage device, a control device, and a communication device for communicating with a server that transmits disaster information. The control method includes a step of controlling the device to save energy when the communication device receives disaster information from the server.

[0020] According to this configuration, it is possible to provide a control method that can reduce the user's sense of anxiety. [Effects of the Invention]

[0021] According to this disclosure, it is possible to provide a disaster response system, a vehicle, and a control method that can reduce the user's sense of anxiety. [Brief explanation of the drawings]

[0022] [Figure 1] 1 is a diagram showing a schematic configuration of a disaster response system according to an embodiment of the present invention. [Figure 2] 10 is a flowchart showing the flow of disaster response processing in the first embodiment. [Figure 3] 10 is a flowchart showing the flow of disaster response processing in the second embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0023] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals and description thereof will not be repeated.

[0024] [First embodiment] Fig. 1 is a diagram showing a schematic configuration of a disaster response system 1 according to this embodiment. Referring to Fig. 1, disaster response system 1 includes a vehicle 100, a server 200 that can communicate with vehicle 100 and exchanges information with vehicle 100, a server 300 that provides disaster information, and a communication network 900. Vehicle 100 is assumed to be a PHEV.

[0025] The vehicle 100 includes an ECU (Electronic Control Unit) 110, a DCM (Data Communication Module) 120, an antenna 121, a GPS (Global Positioning System) 130, a cockpit system ECU 150, an HMI (Human Machine Interface) 151, a drive system ECU 160, a battery 170, an inverter 180, an MG (Motor Generator) 181, a charger 140, an inlet 141, an engine 190, a fuel filler 191, and a fuel tank 192.

[0026] The ECU 110 includes a CPU (Central Processing Unit), a memory, and an input / output port. The CPU processes data stored in the memory or data input from each part of the vehicle 100 according to a program stored in the memory, and outputs the processing result to each part of the vehicle 100 or the memory.

[0027] The DCM 120 is a communication module capable of wireless communication with an external device such as a server 200 via an antenna 121 while exchanging information with the ECU 110 .

[0028] The GPS 130 is controlled by the ECU 110 to determine the current position of the vehicle 100 based on radio waves from artificial satellites. The ECU 110 controls the GPS 130 to determine the current position of the vehicle 100.

[0029] Cockpit system ECU 150 has the same configuration as ECU 110. Cockpit system ECU 150 controls devices around the driver's seat, such as HMI 151, while exchanging information with ECU 110. HMI 151 is a group of devices that output information to the driver and receive information from the driver, and includes, for example, an instrument panel, a head-up display, and a center display including a touch panel.

[0030] The battery 170 stores electric power supplied from an external source, generated by the engine 190, or regenerated by the MG 181, and supplies the electric power to each part of the vehicle 100.

[0031] A charging connector 410 at the tip of a charging cable 420 of power feeding equipment 400 can be attached to and detached from inlet 141. When charging connector 410 is connected to inlet 141, charger 140 converts the power supplied from power feeding equipment 400 into DC power of a voltage according to battery 170, and supplies the converted power to battery 170.

[0032] The drive system ECU 160 has the same configuration as the ECU 110. The drive system ECU 160 exchanges information with the ECU 110 and controls the battery 170, the inverter 180, and the engine 190. Based on a control signal from the drive system ECU 160, the engine 190 generates driving power for the vehicle 100 by burning fuel.

[0033] A fuel nozzle 510 at the end of a fuel hose 520 of a fuel supply equipment 500 can be inserted into the fuel filler port 191. The fuel tank 192 accumulates fuel supplied from the fuel supply equipment 500 via the fuel filler nozzle 510 and the fuel filler port 191, and supplies the fuel to the engine 190.

[0034] Based on a control signal from drive system ECU 160, inverter 180 uses power from battery 170 to supply power for controlling MG 181, and charges battery 170 with regenerative power from MG 181. MG 181 rotates using power from inverter 180 to generate driving power for vehicle 100, and generates regenerative power by braking vehicle 100 and supplies it to inverter 180.

[0035] Server 200 is a computer and includes a processing unit 210 and a communication unit 220. Processing unit 210 includes a CPU, a memory, and a large-capacity storage device. The CPU processes data stored in the memory or the large-capacity storage device or data input from each unit of server 200 in accordance with a program stored in the memory or the large-capacity storage device, and outputs the processing results to each unit of server 200, the memory, or the large-capacity storage device.

[0036] The communication unit 220 exchanges information with the processing unit 210 and performs wireless communication with external parties such as the vehicle 100 and the server 300 via the antenna 221 or via the communication network 900. The server 300 has the same structure as the server 200.

[0037] In the past, when a vehicle such as a PHEV or BEV was connected to a HEMS, there was a system that would start charging the vehicle when the HEMS received an emergency disaster alert. For example, the vehicle's storage battery would be charged using grid power or natural energy. This makes it possible to use the power stored in the vehicle's storage battery after a disaster.

[0038] Furthermore, after a disaster occurs, the HEMS switches to available power depending on the severity of the disaster. Specifically, if grid power is unavailable, the HEMS switches the power source from grid power to an available power source (for example, natural energy or a vehicle battery). This allows for a continuous supply of power to a home equipped with the HEMS.

[0039] Incidentally, it is expected that the above-described vehicle 100 will be used when evacuating in the event of a disaster. Even if the battery 170 of the vehicle 100 is fully charged, as the time that the vehicle 100 can travel decreases, the anxiety of the disaster victims may increase.

[0040] Therefore, vehicle 100 includes a storage device (e.g., battery 170, fuel tank 192) capable of storing an energy source (e.g., electricity, fuel), devices (e.g., MG 181, engine 190, air conditioner, heater, etc.) that operate on the energy source of the storage device, control devices (e.g., ECU 110, drive system ECU 160, and cockpit system ECU 150), and a communication device for communicating with external devices. The control devices perform energy-saving control of the devices on the condition that disaster information is received by DCM 120 from server 200.

[0041] As a result, on the condition that disaster information is received in vehicle 100 from server 200, the devices that operate on the energy source of the storage device are controlled to save energy. This makes it possible to extend the time that the devices in vehicle 100 can operate in the event of a disaster, thereby reducing the user's sense of anxiety.

[0042] 2 is a flowchart showing the flow of disaster response processing in the first embodiment. Referring to FIG. 2, this disaster response processing is called from a higher-level processing by ECU 110 of vehicle 100 at predetermined intervals and executed.

[0043] The ECU 110 of the vehicle 100 determines whether or not disaster information or disaster prevention information has been received from the server 200 by the DCM 120 (step S111). When a disaster is predicted to occur or when a disaster has occurred, the server 300 of a government or private disaster reporting organization transmits the disaster prevention information or disaster information to various locations. Disaster prevention information and disaster information include, for example, emergency earthquake alerts, major tsunami warnings, tsunami warnings, tsunami advisories, earthquake prediction information, seismic intensity information, eruption warnings, crater area warnings, eruption forecasts, special weather warnings (special heavy rain warnings, special storm warnings, special storm surge warnings, etc.), weather warnings (heavy rain warnings, flood warnings, storm warnings, storm surge warnings, wave warnings, heavy snow warnings, etc.), weather advisories (heavy rain advisories, strong wind advisories, heavy snow advisories, etc.), flood occurrence information, flood risk information, flood warning information, flood advisory information, civil protection information (ballistic missile information, etc.), emergency safety information, evacuation order information, evacuation information for the elderly and others, and information on affected areas.

[0044] When it is determined that disaster information or disaster prevention information has been received (YES in step S111), ECU 110 starts energy-saving control of vehicle 100 in accordance with the received disaster information or disaster prevention information (step S114). For example, ECU 110 determines whether the current location of vehicle 100 is included in an area subject to a heavy rain emergency warning, a special storm warning, or the like, that is, whether the current location of vehicle 100 is included in a location where power supply equipment 400 and fuel supply equipment 500 are likely to become unavailable. If the current location of vehicle 100 is included in the area subject to the heavy rain emergency warning, ECU 110 starts energy-saving control of devices of vehicle 100 (e.g., MG 181, engine 190, air conditioner, etc.) that operate on energy sources such as power from battery 170 or fuel from fuel tank 192 in order to extend the operable time of the devices of vehicle 100 (step S114).

[0045] Energy-saving control includes control to limit the maximum output power Wout of battery 170 (control to reduce Wout), control to limit the acceleration of vehicle 100 by MG181 or engine 190, control to limit the upper speed of vehicle 100, and control to stop or reduce power consumption of devices in vehicle 100 that consume a lot of power (e.g., air conditioners, heaters).

[0046] If the location of vehicle 100 is included in an area subject to a special storm surge warning, flood warning, major tsunami warning, tsunami warning, flood occurrence information, flood risk information, emergency safety assurance, evacuation order information, earthquake prediction information, seismic intensity information, eruption warning, crater vicinity warning, or eruption forecast, in other words, if it is advisable to evacuate from the applicable area as soon as possible, ECU 110 may prohibit energy-saving control of devices related to the running of vehicle 100 (for example, MG 181, engine 190). Even in such a case, energy-saving control may be performed on devices not related to the running of vehicle 100 (for example, air conditioner, etc.).

[0047] If it is determined that disaster information or disaster prevention information has not been received (NO in step S111), or after step S114, ECU 110 determines whether or not energy saving control of a device is being executed (step S121).

[0048] If it is determined that energy saving control is being executed (YES in step S121), ECU 110 determines whether a user operation to release the restriction imposed by energy saving control has been executed (step S122). The operation to release the restriction imposed by energy saving control may be input from the touch panel of HMI 151, for example, or may be deemed to have been executed when the accelerator pedal is operated by a predetermined amount or more.

[0049] If it is determined that an operation to remove the restriction has not been performed (NO in step S122), ECU 110 determines whether the disaster information or disaster prevention information received from server 200 has been removed (step S123). If it is determined that the disaster information or disaster prevention information has not been removed (NO in step S123), ECU 110 returns the processing to be executed to the upper-level processing that called this disaster response processing.

[0050] If it is determined that an operation to release the restriction has been performed (YES in step S122), or if it is determined that the disaster information or disaster prevention information has been released (YES in step S123), ECU 110 releases the energy saving control of the devices of vehicle 100 (step S126). After that, ECU 110 returns the process to be executed to the higher-level process that called this disaster response process.

[0051] [Second embodiment] In the first embodiment, it is not taken into consideration whether the power supply equipment 400 and the refueling equipment 500 are in a difficult-to-use state. In the second embodiment, it is taken into consideration whether the power supply equipment 400 and the refueling equipment 500 are in a difficult-to-use state.

[0052] Fig. 3 is a flowchart showing the flow of disaster response processing in the second embodiment. Referring to Fig. 3, this disaster response processing is called from a higher-level processing at predetermined intervals by ECU 110 of vehicle 100 and executed. In the flowchart of Fig. 3, processing with the same step numbers as those in the flowchart of Fig. 2 is the same as the processing described in Fig. 2, and therefore redundant description will not be repeated.

[0053] The ECU 110 of the vehicle 100 determines whether disaster information or disaster prevention information has been received from the server 200 via the DCM 120 (step S111). If it is determined that disaster information or disaster prevention information has been received (YES in step S111), the ECU 110 inquires of the server 200 or another server via the DCM 120 to determine whether the power supply equipment 400 or the refueling equipment 500 within reachable range using the power of the battery 170 and the fuel of the fuel tank 192 of the vehicle 100 without energy-saving control are unavailable due to a disaster or the like, or whether they are difficult to use (step S112). The term "unavailable" may include not only cases where the equipment is completely unavailable, but also cases where the number of available equipment is small or the amount of power or fuel that can be supplied is limited. The server 200 or another server constantly checks whether the power supply equipment 400 and the refueling equipment 500 at each location are unavailable or available.

[0054] The reachable range without energy-saving control using the power of the battery 170 and the fuel in the fuel tank 192 of the vehicle 100 may be any range specified based on the power of the battery 170 and the remaining amount of fuel in the fuel tank 192, but here it is defined as a range specified under the strictest conditions, such as full passenger load or full load, to avoid situations where the vehicle is unable to reach a destination despite being determined to be within the reachable range.

[0055] In addition, when a vehicle 100 inquires whether a power supply equipment 400 or a refueling equipment 500 within its reachable range is in a difficult-to-use state, the server 200 or another server may be configured to confirm whether the power supply equipment 400 or the refueling equipment 500 is in a difficult-to-use state.

[0056] As a result of the identification in step S112, ECU 110 determines whether power supply equipment 400 or refueling equipment 500 is in a difficult-to-use state or is unknown (step S113). If it is determined that power supply equipment 400 or refueling equipment 500 is in a difficult-to-use state or is unknown (YES in step S113), ECU 110 starts energy-saving control of vehicle 100 in accordance with the received disaster information or disaster prevention information, similar to step S114 in FIG. 2 (step S114).

[0057] On the other hand, if it is determined that the power supply equipment 400 or the refueling equipment 500 is not in a difficult to use or unknown state (NO in step S113), that is, that the power supply equipment 400 or the refueling equipment 500 is usable, the ECU 110 starts normal control (non-energy saving control) of the vehicle 100, which is not energy saving control (step S115).

[0058] Then, ECU 110 notifies the user of information about reachable and available power supply equipment 400 or refueling equipment 500 (for example, location, position on a map, type of power supply or refueling) on ​​the display of HMI 151 (step S116).

[0059] If it is determined that disaster information or disaster prevention information has not been received (NO in step S111), after step S114 or after step S116, ECU 110 determines whether or not energy saving control of the device is being executed (step S121). If it is determined that energy saving control of the device is not being executed (NO in step S121), ECU 110 returns the process to be executed to the upper process that called this disaster response process.

[0060] If it is determined that energy saving control of the device is being executed (YES in step S121), ECU 110 determines whether a user operation to release the restriction imposed by the energy saving control has been performed (step S122), similar to step S122 in FIG. 2.

[0061] If it is determined that an operation to remove the restriction has not been performed (NO in step S122), ECU 110, similar to step S112 in FIG. 3, queries server 200 or another server from DCM 120 to determine whether power supply equipment 400 or refueling equipment 500 within reachable range using the power of battery 170 of vehicle 100 and the fuel in fuel tank 192 without energy-saving control is in a state where it is difficult to use due to a disaster or the like, or whether it is unknown whether it is in a state where it is difficult to use (step S124).

[0062] As a result of the identification in step S124, ECU 110 determines whether power supply equipment 400 or refueling equipment 500 is in a difficult-to-use state or is unknown (step S125). If power supply equipment 400 or refueling equipment 500 is not in a difficult-to-use state or is unknown (NO in step S125), that is, if ECU 110 determines that power supply equipment 400 or refueling equipment 500 is usable, ECU 110 cancels the energy saving control of the devices of vehicle 100 (step S126), similar to step S126 in Fig. 2. Thereafter, ECU 110 returns the process to be executed to the higher-level process that called this disaster response process.

[0063] On the other hand, if it is determined that power supply equipment 400 or refueling equipment 500 is difficult to use or is unknown (YES in step S125), ECU 110 performs energy saving control using the power of battery 170 and the fuel in fuel tank 192 of vehicle 100 and determines whether the distance that can be traveled by vehicle 100 is less than a predetermined distance (step S127). The predetermined distance may be the distance to the nearest power supply equipment 400 or refueling equipment 500, or may be a distance within a range that includes a predetermined number (e.g., five) of power supply equipment 400 or refueling equipment 500, or may be a predetermined distance (e.g., several tens of kilometers, specifically, 50 kilometers, 10 kilometers, etc.).

[0064] The distance that can be traveled by performing energy-saving control using the power of the battery 170 of the vehicle 100 and the fuel in the fuel tank 192 can be any distance that can be determined from the power of the battery 170 and the remaining amount of fuel in the fuel tank 192, but here it is defined as the distance determined under the most stringent conditions, such as a vehicle with a maximum number of passengers or a full load.

[0065] When it is determined that the distance that can be traveled by performing energy saving control using the power of battery 170 of vehicle 100 and the fuel in fuel tank 192 has become less than the predetermined distance (YES in step S127), ECU 110 notifies on the display of HMI 151 that it will be difficult to supply power or fuel even if the vehicle continues to travel (step S128). The user who receives this notification can temporarily park vehicle 100 on the side of the road or the like and take evacuation action by other means, such as walking.

[0066] If it is determined that the distance that can be traveled by performing energy saving control using the power of the battery 170 of the vehicle 100 and the fuel in the fuel tank 192 is not less than the predetermined distance (NO in step S127), or after step S128, the ECU 110 returns the processing to be executed to the higher-level processing that called this disaster response processing.

[0067] [Variations] (1) In the above-described embodiment, vehicle 100 is a PHEV as shown in FIG. 1 . However, the present invention is not limited to this, and vehicle 100 may be any vehicle capable of receiving an energy source from an energy source supply facility. For example, vehicle 100 may be a vehicle capable of receiving an electric power supply from a power supply facility (for example, although vehicle 100 is a PHEV in the above-described embodiment, vehicle 100 may be a BEV). Vehicle 100 may also be a vehicle capable of receiving a fuel supply from a fueling facility (for example, gasoline, diesel, alcohol fuel such as biofuel including bioethanol, hydrogen, LPG (Liquid Petroleum Gas), natural gas) (for example, a hybrid electric vehicle (HEV), a gasoline engine vehicle, a diesel engine vehicle, a hydrogen engine vehicle, a fuel cell electric vehicle (FCEV), an LPG vehicle, or a natural gas vehicle).

[0068] (2) In the above-described embodiment, the disaster response process shown in Figures 2 and 3 is executed by ECU 110. However, this is not limiting, and the disaster response process may be executed by another ECU of vehicle 100 (for example, drive system ECU 160 and cockpit system ECU 150).

[0069] (3) In the above-described embodiment, as shown in step S114 in Figures 2 and 3, ECU 110 is configured to perform energy-saving control of devices when the current location of vehicle 100 is included in the target area of ​​disaster information or disaster prevention information. However, this is not limited to this. Server 200 may collect the current locations of multiple vehicles 100, and transmit disaster information or disaster prevention information and information indicating that vehicle 100 is included in the target area to vehicles 100 whose current locations are included in the target area of ​​the disaster information or disaster prevention information, and ECU 110 of vehicle 100 that receives this information may perform energy-saving control of devices.

[0070] (4) In the above-described embodiment, as shown in steps S112 to S114 of FIG. 3 , if there is one power supply facility 400 or one refueling facility 500 determined to be available within the reachable range, vehicle 100 is set to normal control (non-energy saving control). However, this is not limited thereto, and vehicle 100 may be set to normal control (non-energy saving control) if there are several (for example, a predetermined number, specifically, five) power supply facilities 400 or one refueling facility 500 determined to be available within the reachable range. This is because if there is only one power supply facility 400 or one refueling facility 500 determined to be available, there is a possibility that the facility may become unusable depending on the disaster situation.

[0071] (5) The above-described embodiments can be understood as disclosure of the disaster response system 1, as disclosure of the vehicle 100, as disclosure of a disaster response method in the disaster response system 1, or as disclosure of a control method or control program in the vehicle 100.

[0072] [summary] (1) As shown in FIG. 1, disaster response system 1 is a system including vehicle 100 that can receive an energy source (e.g., electricity, fuel) from an external source and server 200 that can communicate with vehicle 100 and transmits disaster information. As shown in FIG. 1, vehicle 100 includes a storage device (e.g., battery 170, fuel tank 192) that can store the energy source, devices (e.g., MG 181, engine 190, air conditioner, heater) that operate using the energy source of the storage device, control devices (e.g., ECU 110, drive system ECU 160, cockpit system ECU 150), and DCM 120 for communicating with external devices. As shown in FIGS. 2 and 3, the control device performs energy-saving control of the devices on the condition that DCM 120 receives disaster information from server 200 (e.g., step S114).

[0073] As a result, on the condition that disaster information is received in vehicle 100 from server 200, the devices that operate on the energy source of the storage device are controlled to save energy. This makes it possible to extend the time that the devices in vehicle 100 can operate in the event of a disaster, thereby reducing the user's sense of anxiety.

[0074] (2) As shown in step S114 in FIGS. 2 and 3, the control device may perform energy-saving control of the devices on the additional condition that the current location of the vehicle 100 is included in the area covered by the disaster information.

[0075] This allows the time during which the equipment of the vehicle 100 can operate to be extended when the vehicle 100 is included in an area affected by disaster information, which may increase the user's sense of anxiety compared to when the vehicle 100 is not included in the area affected by disaster information.

[0076] (3) As shown in Figures 2 and 3, the control device may cancel the energy saving control (e.g., steps S122 to S126) on the condition that the conditions for canceling the energy saving control (e.g., the condition of step S122 in Figures 2 and 3, the condition of step S123 in Figure 2, or the opposite condition of step S125 in Figure 3) are met.

[0077] This allows the control to be returned to normal control, which is not energy saving control, when energy saving control is no longer necessary.

[0078] (4) As shown in FIG. 3, the control device may use the energy source currently stored in the storage device to perform energy-saving control of the equipment (e.g., steps S112 to S114) without performing energy-saving control, with the additional condition that there are no available energy source supply facilities within the range where the vehicle becomes unable to travel.

[0079] As a result, if there is a supply facility with an available energy source within a range where the vehicle cannot travel, the energy source currently stored in the storage device is used without energy-saving control. Therefore, even if a disaster occurs, the vehicle can travel without energy-saving control if it can reach the supply facility. As a result, normal control, not energy-saving control, can be used in situations where the user does not feel anxious.

[0080] (5) As shown in Fig. 1, vehicle 100 further includes HMI 151. As shown in Fig. 3, HMI 151 may be controlled to use the energy source currently stored in the storage device without performing energy saving control, and, if there is a supply facility of an energy source available within a range where vehicle 100 becomes unable to travel, to notify information about the supply facility (for example, step S116).

[0081] As a result, if there is a supply facility that can be reached even in the event of a disaster, information about that supply facility is notified to the user, thereby reducing the user's sense of anxiety.

[0082] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present disclosure is defined by the claims, not by the description of the above embodiments, and is intended to include all modifications within the meaning and scope of the claims.
