[0063] The determination unit 122e determines whether or not the vehicle 101 to the vehicle 102 are receiving power. n The determination unit 122e determines whether or not a vehicle 10 having a power generation function and a remaining amount of fuel equal to or less than a first threshold value has occurred. n In response to this, it is determined whether or not there is a vehicle 10 in which the SOC of the secondary battery 106 is equal to or lower than the second threshold value.

[0064] The output control unit 122f outputs refueling information instructing a vehicle 10 having a power generating function and a remaining amount of fuel equal to or less than a first threshold to refuel, to the communication terminal 50 or the display unit 120e linked to the vehicle 10. The output control unit 122f outputs stop information instructing a vehicle 10 having a SOC equal to or less than a second threshold to stop power supply, to the communication terminal 50 or the display unit 120e linked to the vehicle 10.

[0065] [Vehicle disposal] Next, a process executed by the vehicle 10 will be described. FIG. 4 is a flowchart showing an outline of the process executed by the vehicle 10. Note that, in the following, the process will be described with respect to a plurality of vehicles 101 to 10. nAlthough the process executed by any one of the vehicles 10 will be described, the process executed by all of the vehicles 101 to 10 n Alternatively, the representative vehicle 10 may execute the process as specified by the user.

[0066] As shown in FIG. 4, first, the acquisition unit 122a acquires information on the plurality of vehicles 101 to 102 via the second external communication unit 119. n 101 to 10 n The power supply information and vehicle type information are obtained from each of the above, and power demand information is obtained from the charging / discharging device 20 (step S101).

[0067] Next, the identification unit 122b identifies the plurality of vehicles 101 to 10 n Based on the vehicle type information, the identification unit 122b identifies the vehicle 10 having a power generation function (step S102). n Based on the vehicle type information, HEV, PHEV, and FCEV are identified as the vehicles 10 having a power generation function.

[0068] After that, the acquisition unit 122a acquires the remaining amount of a predetermined fuel from the vehicle 10 identified by the identification unit 122b (step S103).

[0069] Next, the determination unit 122c determines whether the vehicle 101 to the vehicle 102 are included in the vehicle information acquired by the acquisition unit 122a. n Based on the power supply information from each of the vehicles 101 to 10 and the remaining amount of fuel in the vehicle 10 identified by the identification unit 122b, n When a plurality of vehicles 101 to 10 supply power to a facility 40 via a charging / discharging device 20, n Specifically, the determination unit 122c determines the master vehicle 10 that controls the power supply to the vehicles 101 to 10 n Based on the power supply information from each of the vehicles 101 to 10 and the remaining amount of fuel in the vehicle 10 identified by the identification unit 122b, nAmong these, the vehicle 10 with the largest amount of power, calculated by adding together the power supply based on the current SOC and the power generation based on the remaining amount of fuel, is determined to be the master vehicle 10.

[0070] Thereafter, the power supply control unit 122d controls the power supplying unit 122a to supply the power to the plurality of vehicles 101 to 100 based on the power supply information of the master vehicle 10 and the power demand information of the charging / discharging device 20. n Each of the power supply units starts power supply while controlling the amount of power supplied to the facility 40 (step S105).

[0071] Next, the acquisition unit 122a acquires the remaining amount of a predetermined fuel for each vehicle 10 having a power generation function and the remaining amount of the predetermined fuel for each vehicle 101 to 10 n The SOC of the secondary battery 106 is obtained (step S106).

[0072] Next, the determination unit 122e determines whether the plurality of vehicles 101 to 10 n In response to the request, the determination unit 122e determines whether a vehicle 10 with a power generation function and a remaining amount of fuel equal to or less than a first threshold has occurred (step S107). Here, the first threshold is a value of fuel that the vehicle 10 can reach by moving from the current position to a refueling station where a predetermined fuel, for example, gasoline or hydrogen, can be refueled. Of course, the first threshold can be changed as appropriate, and for example, the first threshold can be set by further taking into consideration the congestion or traffic jam on the route to the refueling station, or, if there are multiple refueling stations from the current position of the vehicle 10, the distance to the farthest refueling station can be changed to the value of fuel that can be moved. If the determination unit 122e determines that a vehicle 10 with a power generation function and a remaining amount of fuel equal to or less than the first threshold has occurred (step S107: Yes), the vehicle 10 proceeds to step S108, which will be described later. On the other hand, if the determination unit 122e determines that a vehicle 10 with a power generation function and a remaining amount of fuel equal to or less than a threshold has not occurred (step S107: No), the vehicle 10 proceeds to step S109, which will be described later.

[0073] In step S108, the output control unit 122f outputs refueling information instructing the vehicle 10 having the power generating function and the remaining amount of fuel being equal to or less than the first threshold value to refuel, to the communication terminal 50 or the display unit 120e linked to the vehicle 10. This allows the user of the vehicle 10 having the power generating function and the remaining amount of fuel being equal to or less than the first threshold value to intuitively grasp the timing of refueling the vehicle 10 by checking the refueling information. After step S108, the vehicle 10 proceeds to step S111, which will be described later.

[0074] In step S109, the determination unit 122e determines whether or not the plurality of vehicles 101 to 10 n In response to the determination, the determination unit 122e determines whether or not a vehicle 10 with the SOC of the secondary battery 106 being equal to or lower than the second threshold has occurred. Here, the second threshold is a value of SOC at which the vehicle 10 can move from its current location to a waiting location. Of course, the second threshold can be changed as appropriate, and can be changed to a value that represents the distance that the vehicle 10 can move from its current location toward outside the disaster area. If the determination unit 122e determines that a vehicle 10 with the SOC of the secondary battery 106 being equal to or lower than the second threshold has occurred (step S109: Yes), the vehicle 10 proceeds to step S110, which will be described later. On the other hand, if the determination unit 122e determines that a vehicle 10 with the SOC of the secondary battery 106 being equal to or lower than the second threshold has not occurred (step S109: No), the vehicle 10 proceeds to step S111, which will be described later.

[0075] In step S110, the output control unit 122f outputs stop information instructing the vehicle 10 whose SOC is equal to or less than the second threshold to stop power supply to the communication terminal 50 or the display unit 120e linked to the vehicle 10. This allows the user of the vehicle 10 whose SOC is equal to or less than the second threshold to intuitively know the timing to stop power supply. After step S110, the master vehicle 10 proceeds to step S111, which will be described later.

[0076] Next, the determination unit 122e determines whether the plurality of vehicles 101 to 10 nSpecifically, the determination unit 122e determines whether or not there is a vehicle 10 to which power supply is to be stopped from among the plurality of vehicles 101 to 100 that are receiving power supply through vehicle-to-vehicle communication or the like (step S111). n The vehicle 10 determines whether stop information for stopping power supply has been received from among the vehicle 10 and, if stop information has been received, determines that a vehicle 10 for which power supply is to be stopped has occurred. If the determination unit 122e determines that a vehicle 10 for which power supply is to be stopped has occurred (step S111: Yes), the vehicle 10 proceeds to step S112, which will be described later. On the other hand, if the determination unit 122e determines that a vehicle 10 for which power supply is to be stopped has not occurred (step S111: No), the vehicle 10 proceeds to step S113, which will be described later.

[0077] In step S112, the power supply control unit 122d performs control to increase the amount of power supplied by the master vehicle 10. Specifically, the power supply control unit 122d performs control to increase the amount of power supplied by the master vehicle 10 so as to complement the amount of power supplied by the vehicle 10 that stops power supply to the facility 40. In this case, the power supply control unit 122d gradually increases the amount of power supplied by the master vehicle 10 through vehicle-to-vehicle communication or the like, while gradually decreasing the amount of power supplied by the vehicle 10 that stops power supply to the facility 40. In this way, the master vehicle 10 controls the amount of power supplied by the multiple vehicles 101-10 n By preventing the balance between the amount of power supplied by each of the vehicles 101 to 100 and the amount of power demanded by the facility 40 from being lost, it is possible to prevent the frequency from fluctuating and to maintain the frequency constant. n Even when a large amount of power is supplied by this, the frequency can be maintained constant, so that the devices in facility 40 can be used stably.

[0078] Next, the determination unit 122e determines whether or not the new vehicle 10 is connected to the facility 40 (step S113). Specifically, the determination unit 122e determines whether or not a connection signal indicating that the new vehicle 10 is connected to the charging / discharging device 20 has been input by vehicle-to-vehicle communication or the like, and determines that the new vehicle 10 is connected to the facility 40 if the connection signal has been input. If the determination unit 122e determines that the new vehicle 10 is connected to the facility 40 (step S113: Yes), the vehicle 10 proceeds to step S114, which will be described later. On the other hand, if the determination unit 122e determines that the new vehicle 10 is not connected to the facility 40 (step S113: No), the vehicle 10 proceeds to step S115, which will be described later.

[0079] In step S114, the power supply control unit 122d adjusts the amount of power supplied by the master vehicle 10 and the amount of power supplied by the newly connected vehicle 10 by performing vehicle-to-vehicle communication or the like, and supplies power accordingly. In this case, after a certain period of time has elapsed, for example, after five minutes, the power supply control unit 122d gradually decreases the amount of power supplied by the master vehicle 10 by vehicle-to-vehicle communication or the like, while gradually increasing the amount of power supplied by the newly connected vehicle 10 to the facility 40. In this way, the master vehicle 10 adjusts the amount of power supplied by the multiple vehicles 101-10 n and the amount of power demanded by facility 40 from being out of balance, it is possible to prevent the frequency of the power from fluctuating. Furthermore, after a certain time has elapsed, the power supply control unit 122d gradually decreases the amount of power supplied by the master vehicle 10 while gradually increasing the amount of power supplied to facility 40 by the newly connected vehicle 10, thereby preventing an instantaneous voltage drop, and therefore it is possible to maintain the frequency of the power generated by the generator 102 constant. After step S114, vehicle 10 proceeds to step S117, which will be described later.

[0080] In step S115, the determination unit 122e determines whether or not an external power source is connected to the facility 40 or the charging / discharging device 20. Here, the external power source is a diesel generator, an emergency generator, or the like stored in the facility 40, and is connected to compensate for the amount of power of the vehicle 10 that has stopped supplying power. The determination unit 122e determines whether or not a connection signal indicating that an external power source has been connected to the charging / discharging device 20 has been input via the communication unit 118, and determines that an external power source has been connected when the connection signal has been input. When the determination unit 122e determines that an external power source has been connected to the facility 40 or the charging / discharging device 20 (step S115: Yes), the vehicle 10 proceeds to step S116, which will be described later. On the other hand, when the determination unit 122e determines that an external power source is not connected to the facility 40 or the charging / discharging device 20 (step S115: No), the vehicle 10 proceeds to step S117, which will be described later.

[0081] In step S116, the power supply control unit 122d adjusts the amount of power supplied by the master vehicle 10 and the amount of power supplied by the connected external power source by performing inter-vehicle communication or the like, and supplies power. In this case, the power supply control unit 122d gradually decreases the amount of power supplied by the master vehicle 10, while gradually increasing the amount of power supplied by the connected external power source to the facility 40. In this way, the master vehicle 10 adjusts the amount of power supplied by the multiple vehicles 101 to 10. n By preventing imbalance between the amount of power supply, which is the sum of the amount of power supplied by each of the power sources and the amount of power supplied by the external power source, and the amount of power demanded by the facility 40, it is possible to prevent frequency fluctuations. After step S114, the vehicle 10 proceeds to step S117, which will be described later.

[0082] In step S117, the determination unit 122e determines whether the master vehicle 10 will stop power supply. Specifically, the determination unit 122e determines whether a stop signal to stop power supply has been input from the operation unit 120d by the user operating the operation unit 120d of the car navigation system 120. If the determination unit 122e determines that the master vehicle 10 will stop power supply (step S117: Yes), the vehicle 10 proceeds to step S118, which will be described later. On the other hand, if the determination unit 122e determines that the master vehicle 10 will not stop power supply (step S117: No), the vehicle 10 proceeds to step S119, which will be described later.

[0083] In step S118, the determination unit 122c determines a new master vehicle 10. Specifically, the determination unit 122c determines a new master vehicle 10 from among the plurality of vehicles 101 to 100 having a power generation function, excluding the master vehicle 10. n Among them, the vehicle 10 with the largest remaining amount of fuel is determined to be the next master vehicle 10.

[0084] Next, the determination unit 122e determines whether the vehicles 101 to 10 n The determination unit 122e determines whether or not to stop the power supply to the facility 40 from each of the vehicles 101 to 10 n When it is determined that the power supply to the facility 40 from each of the vehicles 101 to 100 is to be stopped (step S119: Yes), the vehicle 10 ends this process. n If it is determined not to stop the power supply to the facility 40 by each of the above (step S119: No), the vehicle 10 returns to step S106.

[0085] According to the first embodiment described above, the ECU 122 controls the vehicles 101 to 10 n Each of the vehicles 101 to 10 n The ECU 122 then acquires power demand information indicating the amount of power demand of the facility 40 to which each of the vehicles 101 to 100 supplies power based on the power supply information. n Multiple vehicles from 101 to 10 nA master vehicle 10 that controls the power supply of each of the vehicles 101 to 10 is determined based on the power supply information of the master vehicle 10 and the power demand information of the facility 40. n Each of the vehicles 101 to 10 controls the amount of power supplied to the facility 40. n By preventing the balance between the amount of power supplied by each of the vehicles 101 to 100 and the amount of power demanded by the facility 40 from being lost, it is possible to prevent the frequency from fluctuating and to maintain the frequency constant. n Even when a large amount of power is supplied by this, the frequency can be maintained constant, so that the devices in facility 40 can be used stably.

[0086] According to the first embodiment, the ECU 122 controls the vehicle speed of the plurality of vehicles 101 to 10 based on the vehicle type information. n The ECU 122 then determines whether each vehicle 10 has a power generation function using a predetermined fuel, and acquires the remaining amount of the predetermined fuel from the vehicle 10 having the power generation function. n The master vehicle 10 is determined based on the power supply information of the vehicle 10. As a result, the vehicle 10 that supplies the largest amount of power to the facility 40 is set as the master vehicle 10, making it possible to stably supply power to the facility 40 for a long period of time.

[0087] According to the first embodiment, the ECU 122 outputs instruction information to instruct the vehicle 10 having a power generating function, in which the remaining amount of fuel is determined to be equal to or less than a threshold, to replenish fuel. This allows the user of the vehicle 10 having a power generating function, in which the remaining amount of fuel is determined to be equal to or less than a threshold, to intuitively grasp the timing for replenishing fuel.

[0088] According to the first embodiment, when any of the vehicles 10 having a power generation function stops supplying power to the facility 40, the ECU 122 controls the master vehicle 10 to increase the amount of power supplied to the facility 40, thereby supplementing the amount of power supplied by the vehicle 10 having a power generation function that has stopped supplying power to the facility 40. nBy preventing the balance between the amount of power supplied by each of the power sources and the amount of power demanded by the facility 40 from being lost, it is possible to prevent the frequency from fluctuating and to maintain the frequency constant.

[0089] Furthermore, according to the first embodiment, the ECU 122 performs control to adjust the amount of power supplied by the master vehicle 10 and the amount of power supplied by the new vehicle 10 to the facility 40. This makes it possible to prevent an instantaneous voltage drop that occurs when the new vehicle 10 starts supplying power to the facility 40.

[0090] Furthermore, according to the first embodiment, the ECU 122 performs control to reduce the amount of power supplied by the master vehicle 10 to the facility 40 after a certain time has elapsed toward the amount of power immediately after the start of supplying power to the facility 40, while increasing the amount of power supplied by the new vehicle 10 to the facility 40. This makes it possible to prevent an instantaneous voltage drop that occurs when the new vehicle 10 starts supplying power to the facility 40.

[0091] According to the first embodiment, when the vehicle 10 having the power generation function determines that the power supply to the facility 40 is to be stopped, the ECU 122 drives the external power source to start the power supply to the facility 40. n By preventing the balance between the amount of power supplied by each of the power sources and the amount of power demanded by the facility 40 from being lost, it is possible to prevent the frequency from fluctuating and to maintain the frequency constant.

[0092] According to the first embodiment, when the external power source starts supplying power to the facility 40, the ECU 122 performs control to adjust the amount of power supplied from the master vehicle 10 to the facility 40 and the amount of power supplied from the external power source to the facility 40. n By preventing the balance between the amount of power supplied by each of the power sources and the amount of power demanded by the facility 40 from being lost, it is possible to prevent the frequency from fluctuating and to maintain the frequency constant.

[0093] According to the first embodiment, when the master vehicle 10 determines to stop supplying power to the facility 40, the ECU 122 controls the plurality of vehicles 101 to 10 n Based on the power supply information of each of the vehicles 101 to 10 n In order to determine a new master vehicle 10 from among each of the vehicles, the master vehicles 10 can be switched in sequence.

[0094] Furthermore, according to the first embodiment, the ECU 122 determines the vehicle 10 with the largest remaining amount of fuel as the master vehicle 10. Therefore, even if the master vehicle 10 is switched, the plurality of vehicles 101 to 10 can be controlled smoothly for a long period of time. n Each of the above can be fed to the facility 40.

[0095] In the first embodiment, the ECU 122 functions as a control device, but this is not limited to this. For example, the charge / discharge control unit 25 may be provided with the functions of the ECU 122, i.e., an acquisition unit 122a, an identification unit 122b, a decision unit 122c, a power supply control unit 122d, a judgment unit 122e, and an output control unit 122f.
