Description

The present disclosure relates to a vehicle, and more particularly to a technique for supplying electric power from the vehicle to the outside of the vehicle.

A vehicle that supplies electric power to the outside of the vehicle (hereinafter referred to as "external power supply") is disclosed in, for example, Japanese Patent Application Laid-Open No. 2013-017313 (Patent Document 1). In the vehicle described in Patent Document 1, in order to leave the reserved energy amount required for traveling the preset reserved mileage in the vehicle, when the remaining amount of in-vehicle energy approaches the reserved energy amount, external power supply is supplied. I try to limit it.

Japanese Unexamined Patent Publication No. 2013-017313

However, depending on the situation of the vehicle, it is not always preferable to leave the reserved energy amount in the vehicle for the running of the vehicle. For example, if the current position of the vehicle is in the disaster area, there is a high possibility that the charging facility (power supply facility) around the vehicle will run out of power. In such a situation, limiting the external power supply of the vehicle not only reduces the convenience of the user but also may promote the power shortage of the charging facility around the vehicle.

The present disclosure has been made to solve such a problem, and an object thereof is to make it possible to set an appropriate stop condition of external power supply in consideration of a vehicle situation that changes depending on the position of the vehicle.

The vehicle of the present disclosure includes a power feeding device and a control device. The power supply device is configured to perform external power supply to supply electric power to the outside of the vehicle. The control device is configured to control the power supply device so that the external power supply is stopped when the power supply stop condition is satisfied.

The above-mentioned control device is operated by a user when a predetermined condition (hereinafter referred to as "required condition") set by using information regarding the current position of the vehicle (hereinafter referred to as "position-related information") is satisfied. The above power supply device is controlled so that the external power supply is stopped when the power supply stop condition determined by using the result of the user operation for the request is satisfied.

In order to improve user convenience, it is desirable that appropriate power supply stop conditions are automatically set regardless of user operation. However, since the vehicle is used as a means of transportation, the position of the vehicle changes frequently. In addition, the surrounding environment of the vehicle (and thus the condition of the vehicle) changes depending on the position of the vehicle. Depending on the situation of the vehicle, the power supply stop condition may be automatically set, which may rather reduce the convenience of the user.

Therefore, in the vehicle of the present disclosure, when the required condition is satisfied, the user-operated setting of the power supply stop condition is requested. The requirement condition is a geographical condition set by using the position-related information of the vehicle. The position-related information is information indicating the state of the vehicle (whether or not the current position of the vehicle is a disaster-occurring area, etc.) that changes depending on the position of the vehicle. The control device may acquire vehicle position-related information by using, for example, a known service that provides map information, disaster information, etc. (for example, a service provided by the Japan Meteorological Agency, an IT company, a telecommunications company, etc.). can. Further, the above-mentioned power supply stop condition can be set by using the threshold value described below.

For example, when supplying the electric power stored in the in-vehicle battery (power storage device mounted on the vehicle) to the outside of the vehicle, the power supply is stopped when the SOC (State Of Charge) of the in-vehicle battery becomes smaller than a predetermined threshold value. The condition may be satisfied. The SOC indicates the remaining amount of electricity stored, and for example, the ratio of the current amount of electricity stored to the amount of electricity stored in a fully charged state is expressed by 0 to 100%. As a method for measuring SOC, various known methods such as a method based on current value integration (coulomb count) or a method based on estimation of open circuit voltage (OCV) can be adopted.

Further, in a hybrid vehicle configured to be able to run using both the power output from the motor driven by the electric power stored in the in-vehicle battery and the power output from the internal combustion engine, the power is stored in the in-vehicle battery. Not only the electric power but also the electric power generated by using the electric power output from the internal combustion engine (hereinafter, may be referred to as "engine generated electric power") can be supplied to the outside of the vehicle. When supplying the power generated by the engine to the outside of the vehicle, even if the power supply stop condition is satisfied when the remaining fuel amount of the internal combustion engine (for example, the amount of fuel in the fuel tank) becomes smaller than a predetermined threshold value. good.

Hereinafter, the threshold value indicating the power supply stop condition (the above-mentioned threshold value for the SOC of the vehicle-mounted battery, the fuel remaining amount of the internal combustion engine, etc.) may be referred to as a “power supply stop threshold value”. Further, when the external power supply that is continued until the in-vehicle energy that can be used for the external power supply (for example, the electric power stored in the power storage device and the fuel of the internal combustion engine stored in the fuel tank) is exhausted is referred to as "depletion power supply". There is.

In the vehicle of the present disclosure, when the above-mentioned requirement condition is satisfied, the user operates to request the setting of the power supply stop condition, and the user performs the user operation in response to this request to obtain the power supply stop condition in normal times. Can set different power supply stop conditions.

For example, a vehicle that supplies external power may acquire information (position-related information) indicating whether or not the current position of the vehicle is a disaster-occurring area, and determine whether or not the above-mentioned requirements are satisfied. When it is determined from the above position-related information that the vehicle exists in the disaster area, the vehicle control device requests the user to set the power supply stop condition so that the depleted power supply can be permitted by the user operation. You may. By doing so, it becomes possible to supply electric power from the vehicle to an external device (electrical appliances, etc.) by performing depletion power supply and using all the energy stored in the vehicle. As a result, in the event of a disaster, the energy stored in the vehicle can be fully utilized, and the occurrence of power shortage in the charging facility around the vehicle can be suppressed.

In addition, the vehicle that supplies external power obtains information (position-related information) indicating the mileage from the current position of the vehicle to the nearest energy supply facility (charging facility, refueling facility, etc.), and the success or failure of the above-mentioned requirements. You may try to judge. The vehicle control device calculates and calculates the energy required to travel from the current position of the vehicle to the nearest energy supply facility (hereinafter, also referred to as "travel limit value") from the above position-related information. The running limit value can be set as the power supply stop threshold value. When the energy remaining in the vehicle is about to fall below the travel limit value, but the external power supply that is still being executed is not completed, the vehicle control device requests the user to set the power supply stop threshold value by user operation. It may be possible to select whether or not to continue the external power supply (that is, whether or not to reduce the power supply stop threshold value). By doing so, the user can select whether or not to continue the external power supply depending on the situation.

According to the present disclosure, it is possible to set an appropriate stop condition for external power supply in consideration of the vehicle situation that changes depending on the position of the vehicle.

As the secondary battery, for example, a lithium ion battery can be adopted. The battery 11 may include an assembled battery composed of a plurality of secondary batteries (for example, lithium ion batteries) connected in series and / or in parallel. The secondary battery constituting the battery 11 is not limited to the lithium ion battery, and another secondary battery (for example, a nickel hydrogen battery) may be adopted. An electrolytic solution type secondary battery may be adopted, or an all-solid-state type secondary battery may be adopted. Further, as the battery 11, a large-capacity capacitor or the like can also be adopted.

The ECU 30 is configured to estimate the state (SOC, etc.) of the battery 11 based on the output of the monitoring unit.

MG12 is, for example, a three-phase AC rotary electric machine. The output torque of the MG 12 is transmitted to the drive wheels 20 via a power transmission gear (not shown) configured by a speed reducer or the like. The MG 12 can also generate electricity by the rotational force of the drive wheels 20 during the regenerative braking operation of the vehicle 100. Further, the MG 12 can also generate electric power by the power output from the engine 13 (rotational force of the output shaft) to generate the engine generated electric power.

Further prepare. Further, although FIG. 1 shows a configuration in which only one MG is provided, the number of MGs is not limited to this, and a configuration in which a plurality of MGs (for example, two) are provided may be used.

The engine 13 is an internal combustion engine that outputs power by converting the combustion energy generated when the air-fuel mixture is burned into the kinetic energy of movers such as pistons and rotors. The power output from the engine 13 is divided into a power for driving the MG 12 and a power for driving the drive wheels 20 by, for example, a power dividing device (not shown).

The power supply unit 40 is a portion where electric power is output from the vehicle 100 to the outside when external power supply is performed. For example, a power supply device for external power supply (inlet, power supply relay, power conversion device, etc. (not shown)). ) Is included.

By connecting the connector of the power cable connected to the external device 400 to the inlet of the power feeding unit 40, the vehicle 100 is connected to the external device 400 via the power cable. As a result, the vehicle 100 can supply external power to the external device 400.

In the power supply unit 40, the power conversion device and the power supply relay are provided in the current path connecting the battery 11 and the inlet, and the power (DC power) stored in the battery 11 is supplied to the power conversion device. Further, the electric power generated by the MG 12 (engine generated electric power) is also supplied to the power conversion device via the above-mentioned power control unit (not shown). The power conversion device includes, for example, an inverter. The power supply relay is provided, for example, between the power converter and the inlet. When the power supply relay is closed, the power output from the power conversion device is supplied to the inlet. The vehicle 100 obtains power for power supply by performing power conversion in the power conversion device, and supplies the obtained power for power supply from the inlet to the external device 400.

Examples of the external device 400 include a V2H (Vehicle to Home) stand, electric appliances (cooking utensils and lighting used outdoors), and a power storage device of another vehicle. The V2H stand is a device for appropriately exchanging electric power between the vehicle 100 and a house (not shown). The vehicle 100 can supply power to the house through the V2H stand.

The ECU 30 includes a CPU (Central Processing Unit) as an arithmetic unit, a storage device, and input / output ports for inputting / outputting various signals (none of which are shown). The storage device of the ECU 30 includes a RAM (Random Access Memory) as a work memory and a storage (ROM (Read Only Memory), a rewritable non-volatile memory, etc.) for storage. Various controls are executed by the CPU executing the program stored in the storage device. However, the various controls performed by the ECU 30 are not limited to processing by software, but can also be processed by dedicated hardware (electronic circuit).

In the ECU 30, the CPU outputs the acquired information (calculation result, etc.) to a storage device (for example, a rewritable non-volatile memory) and stores it in the storage device. Further, the storage device of the ECU 30 stores information (map, threshold value, etc.) used for the traveling control of the vehicle 100 and the external power supply control in advance.

The input device 31 is a device that receives an instruction from the user. The input device 31 is operated by the user and outputs a signal corresponding to the user operation to the ECU 30. The user can operate the input device 31 to instruct the ECU 30 to start and stop the external power supply. In this embodiment, a touch panel is adopted as the input device 31. However, the present invention is not limited to this, and a push button, a lever, or the like may be adopted as the input device 31. Further, the input device 31 may have a voice recognition function.

On the meter panel 32, for example, the measured values of various instruments (speedometer, odometer, fuel gauge, water temperature gauge, etc.) of the vehicle 100 and the state of the vehicle 100 estimated using the detected values of various sensors ( A warning light (lights up when the warning condition is met) indicating that the seat belt wearing state, door open / closed state, SOC of the battery 11 etc.) and the measured value of the instruments or the state of the vehicle 100 satisfy the predetermined warning condition. ) Is displayed.

The navigation system 33 is configured to perform a route search for finding the optimum route (for example, the shortest route) from the current position of the vehicle 100 to the destination, and display the optimum route found by the route search on the map. .. The navigation system 33 includes a control unit, a storage unit, a touch panel, a GPS (Global Positioning System) module, and a wireless communication device (none of which are shown) described below.

The control unit is configured to include an arithmetic unit (CPU or the like), executes a control program based on a user's input or the like, and performs the above-mentioned route search or the like. The storage unit is a storage device (for example, a hard disk) that stores a control program, a map database, and the like. The touch panel accepts input from the user (input of a destination in route search, etc.) and displays information (map, optimum route, etc.) corresponding to an instruction from the control unit.

The map database stored in the storage unit includes road gradient information, location information (supply spot) of an energy supply facility (hereinafter, simply referred to as “supply facility”) that can be used by the user, and the like. The supply facility is a facility that supplies energy to the vehicle 100, and more specifically, a charging facility that supplies electric power for charging the battery 11 to the vehicle 100, and a fuel (for example, gasoline) for the engine 13 of the vehicle. Includes refueling facilities to supply 100. The location information of the supply facility (the location of the home where the charging facility is installed, etc.) that is not included in the map information may be additionally registered in the map database by the user's input.

The GPS module includes a receiving device that receives a signal from the GPS satellite 301 (hereinafter referred to as "GPS signal"). The navigation system 33 can identify the current position of the vehicle 100 using GPS signals. The method of detecting the current position of the vehicle 100 is arbitrary. For example, in addition to the GPS signal, the output of a gyro sensor (not shown) that detects the rotation (change in orientation) of the vehicle 100 is used for the vehicle. You may calculate the current position of 100.

A wireless communication device is a communication device capable of wireless communication with the outside. The navigation system 33 can perform wireless communication by a wireless communication device, and can receive various information from a data center 302 through a communication network, for example. More specifically, the latest map information is transmitted from the data center 302 to the navigation system 33 at any time, and the navigation system 33 updates the above map database using the received map information. Further, in the event of a disaster, the vehicle 100 receives disaster information from the data center 302. Disaster information includes information about the disaster area. The vehicle 100 can recognize the disaster occurrence area by receiving the disaster information.

The navigation system 33 transmits the possessed information to the ECU 30 in response to the request from the ECU 30.

The communication device 34 includes, for example, a DCM (Data Communication Module). The DCM is a communication device capable of wireless communication with the smart center 303. The vehicle 100 can receive various information (map information, disaster information, etc.) from the smart center 303 through the DCM. Further, the DCM periodically transmits information on the vehicle 100 (state of the vehicle 100, etc.) to the smart center 303. Examples of the DCM include a communication module compliant with a communication standard such as W-CDMA and LTE, and a communication module compliant with a wireless LAN standard such as 802.11.

The smart center 303 holds and manages registered vehicle information (usage history, etc.). An ID for identifying the vehicle is given to each vehicle at the time of registration. The smart center 303 manages the information for each vehicle by using the ID, and updates the information for each vehicle by using the information sent from each vehicle. In addition, an information terminal is registered for each vehicle, and information on the corresponding vehicle (vehicle status, etc.) is stored in the registered information terminal (hereinafter referred to as "registered terminal") on a regular basis or in response to a request. It is sent from the center 303. In addition, predetermined application software (hereinafter, simply referred to as "application") is installed in the registered terminal, and the smart center 303 can display predetermined information on the screen of the registered terminal through the application. Further, the registered vehicle can display predetermined information on the screen of the registration terminal through the smart center 303. In this embodiment, the vehicle 100 is registered in the smart center 303, and the mobile device 200 is a registration terminal of the vehicle 100. In this embodiment, a smartphone is adopted as the mobile device 200. However, the present invention is not limited to this, and instead of a smartphone, a smart watch, a laptop computer, a tablet terminal, a portable game machine, or the like can be adopted.

By the way, if the external power supply is performed without considering the remaining amount of the vehicle-mounted energy, the energy (power source) for traveling the vehicle 100 may be insufficient and the vehicle 100 may not be able to travel to the supply facility. Therefore, in the vehicle 100 according to this embodiment, when a predetermined power supply stop condition is satisfied during execution of the external power supply, the external power supply is forcibly stopped even if the external power supply is not completed. By performing such control, it becomes possible to leave a predetermined amount of energy in the vehicle 100.

In order to improve user convenience, it is desirable that appropriate power supply stop conditions are automatically set regardless of user operation. However, the position of the vehicle 100 changes frequently. Further, the surrounding environment of the vehicle 100 (and by extension, the situation of the vehicle 100) changes depending on the position of the vehicle 100. Depending on the situation of the vehicle 100, the power supply stop condition may be automatically set, which may rather reduce the convenience of the user.

Therefore, in the vehicle 100 according to this embodiment, when the ECU 30 acquires the position-related information of the vehicle 100 and the requirement condition set by using the position-related information of the vehicle 100 is satisfied, the power supply is stopped by the user operation. Request the setting of conditions. The requirement condition is set to be satisfied when it is determined that the user is likely to desire to change the power supply stop condition based on the position-related information of the vehicle 100. The user can set a power supply stop condition different from the normal power supply stop condition by performing the user operation in response to the above request.

Hereinafter, the external power supply control performed by the ECU 30 will be described in detail with reference to FIG. FIG. 2 is a flowchart showing a processing procedure of external power supply control executed by the ECU 30. The process shown in this flowchart is, for example, by requesting the ECU 30 to execute external power supply in a state where external power supply is possible (for example, a state in which the vehicle 100 is connected to the external device 400 via a power cable). Will be executed. The execution request of the external power supply may be an instruction of the user, or may be the satisfaction of a predetermined condition (the arrival of the power supply start time by the timer, etc.).

With reference to FIG. 2, the ECU 30 acquires the position-related information of the vehicle 100 (step S11). Then, the ECU 30 stores the acquired position-related information in the storage device. In this embodiment, as the position-related information of the vehicle 100, information indicating whether or not the current position of the vehicle 100 is a disaster occurrence area is adopted. Such information can be created based on the information received from the navigation system 33 (current position of the vehicle 100, disaster information, etc.). The current position of the vehicle 100 is acquired by the GPS module of the navigation system 33. The disaster information is acquired from the data center 302 by the wireless communication device of the navigation system 33.

Further, in step S11, the ECU 30 has a mileage (hereinafter, "necessary") from the current position of the vehicle 100 to the nearest supply facility (for example, one of a charging facility, a refueling facility, and a home where the charging facility is installed). Further acquire information indicating "mileage"). The above "closest" means that the mileage of the optimum route described below is the shortest. For example, the navigation system 33 performs a route search for finding the optimum route (for example, the shortest route) from the current position of the vehicle 100 to the nearest supply facility based on the map database, and travels corresponding to the found optimum route. By calculating the distance, the required mileage can be obtained. The conditions for the optimum route are not limited to the shortest route and can be set arbitrarily.

Next, the ECU 30 needs to determine how much energy should be left in the vehicle 100 in order to travel to the supply facility closest to the current position of the vehicle 100 (hereinafter referred to as "shortest supply facility"). X1 calculated based on the mileage and corresponding to the calculated remaining amount of in-vehicle energy is set to the power supply stop threshold Th (step S12). X1 corresponds to the remaining amount of in-vehicle energy required for the vehicle 100 to travel to the shortest supply facility.

The power supply stop threshold Th is provided for the remaining amount of in-vehicle energy that can be used for external power supply in the vehicle 100 (hereinafter, may be referred to as “remaining energy amount”). In this embodiment, in the external power supply, the vehicle-mounted energy is used in the order of the electric power stored in the battery 11 and the remaining fuel amount of the engine 13. Correspondingly, in the remaining energy amount of the vehicle 100, the electric power stored in the battery 11 is located above the remaining fuel amount of the engine 13. That is, when the power supply stop threshold Th is equal to or less than the fuel remaining amount of the engine 13, the power supply stop threshold Th becomes a threshold value for the fuel remaining amount of the engine 13, and when the power supply stop threshold Th becomes larger than the fuel remaining amount of the engine 13. The power supply stop threshold value Th becomes a threshold value for the amount of electricity stored in the battery 11.

Hereinafter, an example of a method of setting the power supply stop threshold Th based on the remaining amount of in-vehicle energy required for the vehicle 100 to travel to the shortest supply facility will be described.

The mileage of the vehicle 100 is a distance that can be traveled by the power output from the engine 13 (hereinafter, referred to as "engine mileage") and a distance that can be traveled by the power output from the MG 12 (hereinafter, "motor travel"). Matches the sum with (referred to as "distance"). The engine mileage is determined by the remaining amount of fuel in the engine 13 (the amount of fuel in the fuel tank). The motor mileage is determined by the amount of electricity stored in the battery 11 represented by SOC or the like.

When the required mileage is less than or equal to the engine mileage, power for reaching the shortest supply facility can be generated only by the fuel of the engine 13. In this case, the remaining amount of in-vehicle energy required for the vehicle 100 to travel to the shortest supply facility (and by extension, the power supply stop threshold value Th set corresponding to this) is equal to or less than the remaining amount of fuel in the engine 13. Therefore, the battery 11 is allowed to be completely discharged, and the power supply stop threshold value Th becomes a threshold value for the remaining fuel amount of the engine 13. The power supply stop threshold Th is set at a position indicating the amount required for the vehicle 100 to travel the required mileage in the remaining fuel amount of the engine 13.

When the required mileage is longer than the engine mileage, the vehicle 100 cannot reach the shortest supply facility unless the electric power stored in the battery 11 is used. In this case, the remaining amount of in-vehicle energy required for the vehicle 100 to travel to the shortest supply facility (and by extension, the power supply stop threshold value Th set corresponding to this) becomes larger than the remaining amount of fuel of the engine 13. Therefore, it is prohibited to use the fuel of the engine 13 for external power supply, and the power supply stop threshold value Th becomes a threshold value for the stored amount of the battery 11. For example, by subtracting the engine mileage from the required mileage, the motor mileage required for the vehicle 100 to travel to the shortest supply facility (hereinafter referred to as "required motor mileage") can be obtained. The power supply stop threshold Th is set at a position indicating the amount of electricity stored in the battery 11 that is necessary for traveling the required motor mileage.

Next, the ECU 30 determines whether or not a disaster has occurred at the current position of the vehicle 100 (that is, whether or not the current position of the vehicle 100 is a disaster occurrence area) based on the position-related information of the vehicle 100 acquired in step S11. Is determined (step S13). The determination in step S13 corresponds to the determination as to whether or not the required condition is satisfied.

If it is determined that a disaster has occurred at the current position of the vehicle 100 (YES in step S13), it is determined that the required condition is satisfied, and the process proceeds to step S14. On the other hand, when it is determined that no disaster has occurred at the current position of the vehicle 100 (NO in step S13), it is determined that the required condition is not satisfied, and the process does not go through steps S14, S151, and S152. The process proceeds to step S16.

In step S14, the ECU 30 displays the selection screen A (see FIG. 3) described later on the touch panel of the mobile device 200 (for example, a smartphone) through the smart center 303, and the power supply stop condition by the user operation (user touch panel operation). Request the setting of. Further, the ECU 30 turns on a predetermined warning light displayed on the meter panel 32 to urge the user to operate the mobile device 200 (and thus to set the power supply stop condition). In this embodiment, on the selection screen A, the user is requested to select whether or not to enable exhaustion power supply (selection by user operation). Then, the ECU 30 determines in step S151 whether or not the exhaustion power supply is selected by the user operation. The power supply stop threshold Th is determined using the result of the user operation for the above request, as described below.

FIG. 3 is a diagram showing a screen (selection screen A) for requesting the user to set a power supply stop condition (power supply stop threshold value Th) when the request condition is satisfied.

With reference to FIG. 2 and FIG. 3, when the user presses the “Yes” button of the selection screen A displayed on the touch panel of the mobile device 200 (that is, touches the “Yes” area of the screen), the depletion power supply is supplied. Determining that the selection (YES in step S151), the ECU 30 sets the power supply stop threshold Th for the remaining energy amount of the vehicle 100 to 0 (no remaining amount) in step S152. As a result, exhaustion power supply becomes possible in the external power supply (steps S16 to S19) described later.

On the other hand, when the user presses the "No" button on the selection screen A (that is, touches the "No" area on the screen), it is determined that the depletion power supply is not selected (NO in step S151), and the ECU 30 determines. The power supply stop threshold Th is not changed. That is, the power supply stop threshold value Th set in step S12 is maintained.

Further, even after a predetermined time has elapsed since the selection screen A is displayed on the mobile device 200, the power supply stop condition is not set by the user operation (that is, neither the "Yes" button nor the "No" button is pressed. Even in the case of (not), it is determined that the exhaustion power supply is not selected (NO in step S151), and the ECU 30 does not change the power supply stop threshold Th. That is, the power supply stop threshold value Th set in step S12 is maintained.

With reference to FIG. 2 again, in step S16, the ECU 30 controls the power supply relay of the power supply unit 40, the power conversion device, and the like to execute external power supply to the external device 400. As a result, at least one of the electric power stored in the battery 11 and the electric power generated by the engine generated by the MG 12 is supplied from the vehicle 100 to the external device 400 through the power cable. Although the details will be described later, in this embodiment, the electric power stored in the battery 11 is preferentially supplied to the external device 400 over the electric power generated by the engine.

The ECU 30 sequentially detects at least one of the SOC of the battery 11 and the remaining fuel amount of the engine 13 while the external power supply is being executed, and it is determined in step S17 that the power supply stop condition is satisfied, or the external power supply is performed in step S18. The external power supply is continued until it is determined that the above is completed (steps S16 to S19).

In step S17, it is determined whether or not the amount of remaining energy of the vehicle 100 is equal to or less than the power supply stop threshold value Th.

When it is determined in step S17 that the amount of remaining energy of the vehicle 100 is larger than the power supply stop threshold value Th (NO in step S17), the ECU 30 determines whether or not the external power supply is completed in step S18. When it is determined in step S18 that the external power supply is completed (YES in step S18), in step S19, the ECU 30 controls the power supply relay of the power supply unit 40, the power conversion device, and the like to stop the external power supply. Let me.

In step S18, for example, when the user gives an instruction to stop the power supply through the input device 31 while the external power supply is being executed, it is determined that the external power supply is completed. However, the present invention is not limited to this, and the ECU 30 may determine that the external power supply is completed, for example, when the power supply end time set by the timer arrives at the start of the external power supply.

On the other hand, when it is determined in step S17 that the amount of remaining energy of the vehicle 100 is equal to or less than the power supply stop threshold value Th (YES in step S17), it is determined that the power supply stop condition is satisfied, and in step S19, external power supply is performed. Forced stop is executed. More specifically, the ECU 30 controls the power supply relay of the power supply unit 40, the power conversion device, and the like to forcibly stop the external power supply without waiting for the completion of the external power supply. For example, the ECU 30 opens the power supply relay and opens the system main relay provided in the current path of the battery 11 to cut off the current path of the battery 11.

For example, when the depleted power supply is selected by the user operation in step S151, 0 (no remaining amount) is set in the power supply stop threshold Th for the remaining energy amount of the vehicle 100 in step S152. This allows depletion power supply. In this case, in step S16, first, the electric power stored in the battery 11 is supplied to the external device 400. Then, when the external power supply is continued and the stored amount of the battery 11 is exhausted, the engine generated power is then supplied to the external device 400. Then, when the external power supply is further continued and the remaining fuel amount of the engine 13 is exhausted, it is determined in step S17 that the remaining energy amount of the vehicle 100 is equal to or less than the power supply stop threshold value Th, and the forced stop of the external power supply is executed in step S19. Will be done.

If the depleted power supply is not selected by the user operation in step S151, the power supply stop condition is determined by the power supply stop threshold value Th set in step S12.

For example, in step S12, when the required mileage is equal to or less than the engine mileage, the battery 11 is allowed to be completely discharged, and the power supply stop threshold Th is a threshold value for the remaining fuel amount of the engine 13. In this case, in step S16, first, the electric power stored in the battery 11 is supplied to the external device 400. Then, when the external power supply is continued and the stored amount of the battery 11 is exhausted, the engine generated power is then supplied to the external device 400. Then, when the external power supply is further continued and the remaining fuel amount of the engine 13 reaches the power supply stop threshold value Th (= X1), it is determined in step S17 that the remaining energy amount of the vehicle 100 is equal to or less than the power supply stop threshold value Th. The forced stop of the external power supply is executed in S19.

Further, in step S12, when the required mileage is longer than the engine mileage, it is prohibited to use the fuel of the engine 13 for external power supply, and the power supply stop threshold Th is the threshold value for the stored amount of the battery 11. Become. In this case, in step S16, the electric power stored in the battery 11 is supplied to the external device 400. Then, when the external power supply is continued and the stored amount of the battery 11 reaches the power supply stop threshold value Th (= X1), it is determined in step S17 that the remaining energy amount of the vehicle 100 is equal to or less than the power supply stop threshold value Th, and in step S19. Forced stop of external power supply is executed. In this case, the external power supply by the engine generated power is not performed.

In the process of FIG. 2, the ECU 30 determines the success or failure of the required condition before starting the external power supply (step S13), and if the required condition is satisfied (YES in step S13), the power supply stop condition is set by the user operation. (Step S14), and the power supply device (power supply relay of the power supply unit 40, power conversion device, etc.) so that the external power supply is stopped when the power supply stop condition determined by using the result of the user operation for the request is satisfied. ) (Steps S16 to S19). The power supply stop threshold Th is determined (maintained or changed) based on the result of the user operation (steps S14, S151, and S152).

Further, when the above requirement condition is not satisfied (NO in step S13), the ECU 30 does not request the setting of the power supply stop condition by the user operation, and when the power supply stop condition set in step S12 is satisfied, the external power supply stop condition is satisfied. The above power supply device is controlled so that the power supply is stopped (steps S16 to S19).

According to the process of FIG. 2, when the vehicle 100 performs external power supply, if it is determined that the vehicle 100 exists in the disaster area (YES in step S13), the power supply stop condition is set for the user. Required. In response to such a request, the user can operate the operation unit (for example, a touch panel) of the mobile device 200 to allow the exhaustion power supply. By doing so, it becomes possible to supply electric power from the vehicle 100 to the external device 400 (electrical appliances, etc.) by performing depletion power supply and using all the energy stored in the vehicle 100. As a result, in the event of a disaster, the energy stored in the vehicle 100 can be fully utilized, and the occurrence of power shortage in the charging facility around the vehicle 100 can be suppressed.

[Embodiment 2]
The vehicle according to the second embodiment of the present disclosure will be described. Since the second embodiment has many parts in common with the first embodiment, the differences will be mainly described, and the description of the common parts will be omitted.

The vehicle according to the second embodiment basically has a configuration similar to that of the vehicle according to the first embodiment. However, in the vehicle according to the second embodiment, the ECU 30 is configured to perform the process of FIG. 4 instead of the process of FIG. Hereinafter, the external power supply control performed by the ECU 30 in the second embodiment will be described in detail with reference to FIG.

FIG. 4 is a flowchart showing a processing procedure of external power supply control executed by the ECU 30 in the vehicle according to the second embodiment. The process shown in this flowchart is called and executed from the main routine when, for example, an external power supply execution request is made in a state where external power supply is possible.

With reference to FIG. 4, the ECU 30 acquires the position-related information of the vehicle 100 (step S21). Then, the ECU 30 stores the acquired position-related information in the storage device. In this embodiment, information indicating the mileage (required mileage) to the shortest supply facility is adopted as the position-related information of the vehicle 100. Since the method of acquiring the information indicating the required mileage is the same as that of the first embodiment (see step S11 in FIG. 2), the description thereof will be omitted.

Next, as in the first embodiment (see FIG. 2), the ECU 30 obtains X1 using the required mileage described above, and sets X1 in the power supply stop threshold Th. (Step S12). X1 corresponds to the remaining amount of in-vehicle energy required for the vehicle 100 to travel to the shortest supply facility.

Next, the ECU 30 executes the external power supply in step S23, and continues the external power supply until it is determined in step S24 that the external power supply is completed or the power supply interruption condition is satisfied in step S25 (step S23). ~ S25). While the external power supply is being executed, the ECU 30 detects at least one of the SOC of the battery 11 and the remaining fuel amount of the engine 13 at a predetermined cycle. Since the processes of steps S23 and S24 are the processes according to steps S16 and S18 of FIG. 2, respectively, the description thereof will be omitted.

When it is determined in step S24 that the external power supply is not completed (NO in step S24), in step S25, the ECU 30 determines whether or not the remaining energy amount of the vehicle 100 approaches the power supply stop threshold Th. .. More specifically, it is determined whether or not the amount of remaining energy is smaller than the value (= Th + offset value) obtained by adding a predetermined offset value to the power supply stop threshold Th (= X1). The offset value can be set arbitrarily. The offset value may be a fixed value or may be variable depending on the state of the battery 11 (battery temperature, etc.). The determination in step S25 corresponds to the determination as to whether or not the required condition is satisfied.

When it is determined that the remaining energy amount of the vehicle 100 is less than "Th + offset value" (YES in step S25), it is determined that the power supply interruption condition is satisfied, and in step S26, the ECU 30 externally supplies power. Is interrupted, and the selection screen B (see FIG. 5) described below is displayed on the touch panel of the mobile device 200 through the smart center 303. The selection screen B displayed on the mobile device 200 requests the user to set the power supply stop condition. Further, in order to notify the user of this request, the ECU 30 turns on a predetermined warning light displayed on the meter panel 32.

FIG. 5 is a diagram showing a screen (selection screen B) for requesting the user to set a power supply stop condition (power supply stop threshold value Th) when the request condition is satisfied.

With reference to FIG. 4 and FIG. 5, when the user presses the “Yes” button on the selection screen B displayed on the touch panel of the mobile device 200, depletion power supply (continuation of power supply) is selected (YES in step S151). ), The ECU 30 sets 0 (no remaining amount) in the power supply stop threshold Th for the remaining energy amount of the vehicle 100 in step S152. As a result, exhaustion power supply becomes possible in the external power supply (steps S16 to S19) described later.

On the other hand, when the user presses the "No" button on the selection screen B, it is determined that the exhaustion power supply (continuation of power supply) is not selected (NO in step S151), and the ECU 30 stops the power supply set in step S12. Do not change the threshold Th.

Further, even if the user operation is not performed even after a predetermined time has elapsed since the selection screen B is displayed on the mobile device 200, the exhaustion power supply (continuation of power supply) is not selected (NO in step S151). The ECU 30 does not change the power supply stop threshold value Th set in step S12.

With reference to FIG. 4 again, the ECU 30 restarts the external power supply in step S16. Subsequent steps S16 to S19 are the same as those in the first embodiment (see FIG. 2), and thus the description thereof will be omitted.

In the process of FIG. 4, the ECU 30 determines whether or not the required condition is satisfied during the external power supply (step S25), and if the required condition is satisfied (YES in step S25), the external power supply is interrupted and the user operates. Requests the setting of the power supply stop condition by (step S26), and the power supply device (power supply of the power supply unit 40) stops the external power supply when the power supply stop condition determined by using the result of the user operation for the request is satisfied. (Relays, power converters, etc.) are controlled (steps S16 to S19). The power supply stop threshold Th is determined (maintained or changed) based on the result of the user operation (steps S26, S151, and S152).

Further, when the above-mentioned requirement condition is not satisfied (NO in step S25), the ECU 30 does not request the setting of the power supply stop condition by the user operation, and controls the above-mentioned power supply device so as to continue the external power supply (NO). Steps S23 to S25).

According to the process of FIG. 4, X1 (travel limit value) corresponding to the remaining amount of in-vehicle energy required for the vehicle 100 to travel to the shortest supply facility is set to the power supply stop threshold Th (step S12). In step S12, such a power supply stop threshold Th (= X1) is automatically set based on the position-related information of the vehicle 100, so that the workload of the user can be reduced. Further, even if the remaining energy amount of the vehicle 100 is about to fall below X1, if the external power supply that is still being executed is not completed (YES in step S25), the user is required to set the power supply stop condition. (Step S26). In response to such a request, the user can select whether or not to continue the external power supply (whether or not to change the power supply stop threshold Th) by operating the operation unit (for example, the touch panel) of the mobile device 200. .. By doing so, the user can select whether or not to continue the external power supply depending on the situation.

[Embodiment 3]
The vehicle according to the third embodiment of the present disclosure will be described. The third embodiment is a combination of the first embodiment and the second embodiment. More specifically, in the vehicle according to the third embodiment, the ECU 30 is configured to perform the process shown in FIG.

FIG. 6 is a flowchart showing a processing procedure of external power supply control executed by the ECU 30 in the vehicle according to the third embodiment. The process shown in this flowchart is called and executed from the main routine when, for example, an external power supply execution request is made in a state where external power supply is possible.

With reference to FIG. 6, the ECU 30 acquires the position-related information of the vehicle 100 in the same manner as in the first embodiment (see FIG. 2) (step S11). The position-related information of the vehicle 100 includes the position-related information adopted in the first embodiment (information indicating whether or not the current position of the vehicle 100 is a disaster-occurring area) and the position-related information adopted in the second embodiment (information indicating whether or not the current position of the vehicle 100 is a disaster-occurring area). Information indicating the required mileage of the vehicle 100) and. Since each step shown in FIG. 6 is the same as that of the first and second embodiments (see FIGS. 2 and 4), the description thereof will be omitted.

According to the process of FIG. 6, it is possible to set an appropriate stop condition for external power supply in consideration of the situation of the vehicle 100 (presence or absence of a disaster and the required mileage) that changes depending on the position of the vehicle 100.

[Other embodiments]
In each of the above embodiments, the selection screen A or B is displayed on the mobile device 200, and the user-operated setting of the power supply stop condition is requested. Since the power supply stop condition can be easily set by operating the mobile device 200, the convenience of the user is high. However, the present invention is not limited to this, and a screen for requesting the user to set the power supply stop condition (for example, the selection screen A or B) may be displayed on the touch panel of the input device 31 or the navigation system 33. Further, the user may be requested to set the power supply stop condition by voice.

In each of the above embodiments, in response to a request for setting a power supply stop condition (for example, selection screen A or B), external power supply is started by a timeout even if the user does not input, but the user does not time out. You may wait for input. Further, the user may arbitrarily set the on / off of the timeout and the time until the timeout.

On the selection screens A and B (FIGS. 3 and 5), a user operation is requested to select from two options (“Yes” / “No”), but the number of options may be three or more. Further, the required user operation is not limited to selection from predetermined options, and may be numerical input. For example, the user may be able to input an arbitrary numerical value smaller than the current value as the power supply stop threshold Th. Further, the user operation may be voice input.

In each of the above embodiments, the ECU 30 may acquire information (disaster information, map information, traffic jam information, etc.) used for creating position-related information from the smart center 303.

The position-related information is arbitrary as long as it is information regarding the current position of the vehicle 100. Examples of position-related information include, in addition to the position-related information adopted in the first to third embodiments, information indicating whether or not a disaster has occurred in an area near the current position of the vehicle (around the vehicle), and a vehicle. Information indicating the energy required for the vehicle to reach the supply facility in the vicinity of the vehicle, information indicating whether or not there is a supply facility at the current position of the vehicle, and the like can be mentioned.

For example, when a disaster occurs in the vicinity of the vehicle 100, the above-mentioned requirements may be satisfied even if a disaster does not occur at the current position of the vehicle 100.

Further, in step S12 (FIGS. 2, 4, and 6), X1 was obtained by considering only the mileage of the optimum route determined by the navigation system 33, but the road gradient and congestion information on the optimum route are also obtained. In consideration, the energy required for the vehicle 100 to reach each supply facility around the vehicle 100 may be calculated. Then, instead of the shortest supply facility adopted in the first to third embodiments, the supply facility that requires the least energy for the vehicle 100 to reach may be adopted.

Further, when the external power supply is performed by the vehicle 100 parked in the parking lot of the home where the charging facility is installed, the exhaustion power supply may be permitted by the user operation. By doing so, when a power outage occurs around the home and power is no longer supplied to the home, power is exhausted and power is supplied from the vehicle 100 to the home (house) using all the energy stored in the vehicle 100. Will be able to be supplied.

The configuration of the vehicle is not limited to the configuration shown in FIG. 1, and can be appropriately changed. For example, the vehicle is not limited to a hybrid vehicle, and may be an electric vehicle without an engine. For electric vehicles, refueling facilities do not correspond to supply facilities. The external power supply method is also arbitrary, and may be, for example, a method of supplying power to the outside in a non-contact manner without using a cable (wireless power supply method).

The embodiments disclosed this time should be considered to be exemplary and not restrictive in all respects. The scope of the present invention is shown by the scope of claims rather than the description of the embodiments described above, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
