DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle capable of transmitting electric power generated inside a vehicle to the outside of the vehicle.

[0002]

The vehicle is driven by the prime mover mounted thereon, but is not used at all when the vehicle is not running. That is, when the vehicle is not in use, it is stopped in a parking lot or the like, and its functions are completely stopped. Vehicles are by no means inexpensive, and it is wasteful to leave them completely disabled. Therefore, the present invention has been invented from the viewpoint of effectively utilizing the vehicle even when the vehicle is not operating (when the vehicle is stopped).

An object of the present invention is to provide a vehicle capable of efficiently generating power when the vehicle is stopped and transmitting the power efficiently to the outside of the vehicle.

[0004]

A vehicle according to the present invention is a hybrid drive type vehicle including an internal combustion engine for driving the vehicle, an electric motor, and a generator for generating electric power for driving the electric motor. It has a power transmission means for transmitting the power generated by using the power supply to the outside of the vehicle.
According to the vehicle of the present invention, when the vehicle is not in operation (when the vehicle is stopped), power is generated using the generator mounted on the vehicle,
Since this electric power can be transmitted to the outside of the vehicle and used, the vehicle can be effectively used even when the vehicle is not in operation (when the vehicle is stopped).

Here, the generator preferably generates AC power, and the power transmission means preferably transmits the power generated by the generator as AC power to the outside of the vehicle. This facilitates power transmission and improves power transmission efficiency. Here, it is preferable that the power generator generates power using the output of the internal combustion engine. Since the internal combustion engine that drives the vehicle is used, power can be generated using the existing vehicle structure.

Here, it is preferable to use gaseous fuel for driving the internal combustion engine at the time of power generation by the generator when the vehicle is stopped. Here, it is preferable to further include heat supply means for supplying heat generated by the internal combustion engine to the outside of the vehicle at the time of power generation by the generator when the vehicle is stopped. The internal combustion engine
Since heat is also generated when the vehicle is driven at the time of power generation by the generator when the vehicle is stopped, by supplying this heat to the outside of the vehicle using the heat supply means, the heat can also be used effectively.

Here, the type of fuel supplied to the internal combustion engine during power generation by the generator when the vehicle is stopped is made different from the type of fuel supplied to the internal combustion engine during operation of the vehicle. Is preferred. Different types of fuel to be supplied to the internal combustion engine when power is generated when the vehicle is stopped and types of fuel to be supplied to the internal combustion engine when the vehicle is operating, so that the fuel (power generation fuel / running fuel) suited to each situation can be used properly. Thus, the internal combustion engine can be operated in a more suitable state in each state (during power generation and running).

Here, it is preferable that the method of supplying fuel to the internal combustion engine during power generation by the generator when the vehicle is stopped is made different from the method of supplying fuel to the internal combustion engine during operation of the vehicle. By making the method of supplying fuel to the internal combustion engine different between power generation and operation, the most efficient operation can be performed during power generation, and at the same time, operation can be performed that satisfies the performance required for vehicles. .

[0009] Here, it is preferable that the power generation fuel for driving the internal combustion engine is introduced from outside the vehicle when the power is generated by the generator when the vehicle is stopped. By supplying fuel for power generation to the vehicle from the outside,
The fuel storage amount on the vehicle side does not change, and the vehicle does not run out of fuel after power generation. In addition, when power generation is attempted using fuel mounted on the vehicle, the time during which power generation can be performed is limited. However, if fuel for power generation is supplied from outside the vehicle, the amount of fuel stored in the vehicle will be reduced. Power generation can be performed for a long time without changing.

Preferably, the fuel for power generation is a gaseous fuel, and the fuel cell further includes a compression means for compressing the introduced gaseous fuel, and a storage means for storing the compressed gaseous fuel. With such a storage means, it becomes possible to replenish the vehicle operating fuel using the power generating fuel supplied from outside the vehicle. At this time, if the gas fuel is not compressed, the mounted volume of the vehicle becomes large. Therefore, the gas fuel is compressed by using the compression means and then stored in the storage means, so that the gas fuel can be efficiently stored. The storage of the fuel for power generation in the storage means may be performed at the time of power generation or power transmission, or may be performed at other times.

Here, it is preferable that the fuel for power generation introduced from outside the vehicle when the vehicle is stopped is a low-pressure gas fuel. By supplying the low-pressure gas fuel from the outside, the trouble of depressurizing the high-pressure gas is eliminated, the fuel can be supplied to the internal combustion engine as it is, and power generation can be performed efficiently. Further, if the low-pressure gas fuel is supplied to the internal combustion engine, it is possible to supply the low-pressure gas fuel to the internal combustion engine as it is by utilizing the negative pressure of the intake pipe, so that useless energy is not consumed.

Here, control means for controlling the operation of the internal combustion engine is provided. The control means controls the control mode of the internal combustion engine in a mode for power generation by the generator when the vehicle is stopped and a mode for vehicle operation when the vehicle is running. It is preferable to switch between the modes. By switching the control mode of the internal combustion engine between the vehicle operation mode and the power generation mode, it is possible to control the internal combustion engine according to the respective situations during operation or power generation. For example, when the vehicle is running, the vehicle also starts and accelerates rapidly, so the internal combustion engine must cope with various transient loads in a wide range, but the most energy efficient when generating power when the vehicle is stopped What is necessary is just to operate | move constantly in an area | region.

Here, the vehicle has a power transmission line connecting portion to which a power transmission line for transmitting the electric power generated by the generator when the vehicle is stopped to the outside of the vehicle is connected, and the control means includes a power transmission line connected to the power transmission line connecting portion. In this case, it is preferable to switch the control mode of the internal combustion engine to the power generation mode. With this configuration, the control mode of the internal combustion engine is automatically switched by the power transmission preparation action of connecting the power transmission line to the power transmission line connection part on the vehicle side, so that the power transmission procedure can be simplified, The control mode of the internal combustion engine can be reliably switched.

[0014] In addition, a receiving pipe connecting portion for connecting a receiving pipe for introducing fuel for power generation of the internal combustion engine from outside of the vehicle at the time of power generation by the generator when the vehicle is stopped is provided.
It is preferable that the control means switches the control mode of the internal combustion engine to the power generation mode when the receiving pipe is connected to the receiving pipe connecting portion. In this case, the control mode of the internal combustion engine is automatically switched by the power generation preparation action of connecting the receiving pipe to the receiving pipe connecting portion on the vehicle side.
The power generation procedure can be simplified, and the control mode of the internal combustion engine can be reliably switched.

Here, the control mode of the internal combustion engine is
Switching means for switching between a mode for power generation by the generator when the vehicle is stopped and a mode for vehicle operation during vehicle operation may be provided. By providing such switching means, the control mode of the internal combustion engine can be set to a desired control mode as needed.

[0016] Here, there are provided control means for controlling the operation of the internal combustion engine, and a transmission line connection portion to which a transmission line for transmitting electric power generated by the generator when the vehicle is stopped to the outside of the vehicle is connected. Preferably, when the transmission line is not connected to the transmission line connection part, the switching of the control mode of the internal combustion engine by the switching means is preferably prohibited. By doing so, it is possible to reliably prevent generation of power even when the transmission line is not connected.

In this case, the control mode of the internal combustion engine is set to the power generation mode only when the brake is applied by the parking brake and the gear position is in the parking position in the automatic transmission vehicle and in the neutral position in the manual transmission vehicle. It is preferable to be configured to be able to switch to the mode. By doing so, safety during power generation can be reliably ensured.

[0018] The vehicle of the present invention is a vehicle equipped with a fuel cell, characterized in that it has power transmission means for transmitting electric power generated using the fuel cell to the outside of the vehicle when the vehicle is stopped. According to the vehicle of the present invention, when the vehicle is not in operation (when the vehicle is stopped), power is generated using the fuel cell mounted on the vehicle, and this power can be transmitted to the outside of the vehicle for effective use. Therefore, the vehicle can be effectively used even when the vehicle is not in operation (when the vehicle is stopped).

Here, when power is generated by the fuel cell when the vehicle is stopped, it is preferable that fuel for power generation supplied to the fuel cell is introduced from outside the vehicle. If the fuel for power generation is supplied to the vehicle from the outside, the amount of fuel stored in the vehicle does not change, and the vehicle does not run out of fuel after power generation. In addition, when power generation is attempted using fuel mounted on the vehicle, the time during which power generation can be performed is limited. However, if fuel for power generation is supplied from outside the vehicle, the amount of fuel stored in the vehicle will be reduced. Power generation can be performed for a long time without changing.

[0020] Further, it is preferable that the apparatus further comprises a transmission means for transmitting information on the power transmitted outside the vehicle to a power transmission destination. As described above, by transmitting the information on the power to be transmitted to the power transmission destination, the power can be efficiently used at the power transmission destination. Conversely, it is also preferable to include a receiving unit that receives information on the power transmitted to the outside of the vehicle from the power transmission destination. As described above, by receiving information on the power transmitted to the power transmission destination, it becomes possible to efficiently generate power based on this information.

In this case, it is preferable that a transmission means is provided for transmitting information on the fuel for power generation introduced from outside the vehicle to a source of the fuel for power generation. By doing so, the power transmission destination can efficiently supply the fuel for power generation by obtaining information on the fuel for power generation required by the vehicle. Conversely, it is also preferable to include a receiving unit that receives information on the fuel for power generation introduced from outside the vehicle from a source of the fuel for power generation. As described above, by receiving the information on the fuel for power generation, the introduced fuel for power generation can be efficiently consumed, and the power can be efficiently generated.

Here, the power transmission means preferably transmits the generated AC power to the outside of the vehicle in a non-contact manner using electromagnetic induction. As described above, if the power transmission is performed in a non-contact manner by using the electromagnetic induction, it is possible to suppress the leakage of electricity between the vehicle and the power transmission destination. In addition, since operations such as connection of power transmission lines are not required, preparation is simplified.

Here, it is preferable to include a safety measure executing means for executing a safety measure at the time of power generation or power transmission when the vehicle is stopped. By means of implementing safeguards,
Since safety measures are performed, safety during power generation or transmission is ensured. Specifically, the following safety measures are taken.

The safety measure execution means stops power generation or power transmission when the movement of the vehicle is detected. The safety measure execution means locks the door of the vehicle at the time of power generation or power transmission when the vehicle is stopped. When the vehicle door is opened at the time of power generation or power transmission when the vehicle is stopped,

The vehicle further includes vibration detection means for detecting a vibration state of the vehicle, and the safety measure execution means stops power generation or power transmission when the vibration state of the vehicle detected by the vibration detection means becomes larger than a predetermined state. The vehicle further includes temperature detection means for detecting the temperature around the vehicle, and the safety measure execution means stops power generation or power transmission when the temperature around the vehicle detected by the temperature detection means becomes higher than a predetermined temperature.

Further, a power transmission section for transmitting the electric power generated when the vehicle is stopped and a receiving pipe connecting section for connecting a receiving pipe for introducing fuel for power generation from outside of the vehicle at the time of power generation when the vehicle is stopped are provided on the vehicle body side. Preferably, the power receiving unit includes a power receiving unit that receives power transmitted from the power transmitting unit and a power receiving unit that is connected to the power receiving tube connecting unit, and includes a power receiving unit that is attached to a power transmission destination of the generated power.

When the vehicle is provided with such a power receiving unit, the power generated by the vehicle can be transmitted to the power receiving unit simply by installing the power receiving unit at the power transmitting destination and laying a pipe or wiring to the power receiving unit. It is available and very convenient. Further, the fact that the vehicle body and the power receiving unit are set as described above means that the specifications of the two (the specifications relating to power generation, the specifications relating to power reception, the specifications relating to communication between the two, etc.) are harmonized with each other. This is preferable in performing power generation and charging.

Here, it is preferable that the apparatus further includes communication means for communicating information regarding power generation when the vehicle is stopped between the vehicle body and the power receiving unit. By exchanging information regarding power generation between the vehicle body and the power receiving unit, power generation can be efficiently performed and power generation can be reliably controlled.

Here, it is preferable that the power receiving unit has a shut-off valve for shutting off the supply of the fuel for power generation to the vehicle body through the receiving pipe. If the power receiving unit has a shut-off valve as described above, the shut-off valve is closed first at the end of power generation, and if the fuel for power generation in the receiving pipe is used up, the receiving pipe is removed from the vehicle after the end of power generation. However, the fuel for power generation does not remain inside the receiving pipe.

The warning lamp 52 is used when an abnormality occurs in the power generation on the vehicle 1 side, when an abnormality occurs in the supply and demand of the electric power between the vehicle 1 and the house 30, or when a situation occurs in which the house 30 needs to stop charging. It is lit. These situations are received EC

I have. Further, the power receiving unit 44 may have a buzzer that sounds when an abnormality occurs, instead of the warning lamp 52.

Information regarding the reception of electric power is exchanged between the vehicle 1 and the house 30 by communication. For this reason, as shown in FIG. 2, a transceiver 53 is connected to the power generation ECU 6, and a transceiver 54 is also connected to the power receiving ECU 45. In the present embodiment, communication between the power generation ECU 6 and the power reception ECU 45 is performed by wire communication using the communication line 55.

In this embodiment, the power generation ECU 6-
The communication between the power receiving ECUs 45 is performed by wire, but may be performed wirelessly. Furthermore, in the present embodiment, power is transmitted from the vehicle 1 to the house 30 using the power transmission line 24, but power may be transmitted in a non-contact manner using electromagnetic induction. In this case, coils are built in the vehicle 1 and the power receiving unit 44, respectively. On the vehicle 1 side, the generated power is passed through a coil, and the current flowing through this coil is changed. The magnetic flux is generated by the fluctuation of the current flowing through the coil, and the magnetic flux also fluctuates. On the power receiving unit 44 side, an electromotive force is generated at both ends of the coil due to the fluctuating magnetic flux, and this is taken out as electric power.

The above-described pair of coils is mounted on the vehicle 1 and the power receiving unit 4 so that the distance is as small as possible.
4 is preferred. By doing so, the change in the magnetic flux generated on the vehicle 1 side can be more efficiently applied to the coil on the power receiving unit 44 side. In this case, it is preferable that a mechanism for clarifying the stop position of the vehicle 1 be constructed in the parking lot of the vehicle 1 or the like in order to more accurately position the pair of coils. As described herein, if power is transmitted in a non-contact manner using electromagnetic induction, a leakage between the vehicle 1 and the power receiving unit 44 can be suppressed.

As described above, when power is transmitted using electromagnetic induction, the current flowing through the coil of the vehicle 1 is changed. Therefore, the power generated by the generator 4 is preferably AC. . In the case of alternating current, it is easy to periodically change the current flowing through the coil, so that power transmission using electromagnetic induction is facilitated.

The process of generating power using the vehicle 1 having the above-described configuration and transmitting the generated power to the house 30 will be described step by step.

The vehicle 1 is stopped in a parking space associated with the house 30. Receiving pipe 21, transmission line 24, heat transmission pipe 27

It is preferable that the communication line connection unit 56 is also integrated in one place, since these connections can be performed collectively. When the communication is performed wirelessly or the power transmission is performed in a non-contact manner as described above, since the communication line 55 and the transmission line 24 do not exist, it is needless to say that the vehicle is not connected to the vehicle 1.

Next, the mode switch 1 on the vehicle 1 side
Using 8, the operation mode of the engine 2 is set to the power generation mode side. As described above, by switching the operation mode of the engine 2 between the operation mode and the power generation mode, it is possible to control the engine 2 according to the respective situations during vehicle operation and during power generation. For example, during the operation of the vehicle, the vehicle 1 also performs sudden start and sudden acceleration, so that the engine 2 has to cope with various transient loads in a wide range. However, at the time of power generation when the vehicle is stopped, it is only necessary to operate the vehicle constantly in the region with the highest energy efficiency.

The engine 2 is controlled by the engine ECU 7
Control is performed according to each operation mode. If the mode changeover switch 18 is provided as in this embodiment, such an operation mode (control mode) of the engine 2 is provided.
Can be artificially switched, so that the operation mode of the engine 2 can be set artificially and reliably, which is convenient.

At this time, the power generation ECU 6 or the engine ECU 7
To ensure safety during power generation, if the parking brake is in the braking state and the gear position is not in the predetermined position (parking position for automatic transmission vehicles, neutral position for manual transmission vehicles) However, the mode switching to the power generation mode is not performed. By doing so, safety during power generation can be reliably ensured. The state of the parking brake is detected by a parking brake sensor 38, and the gear position is detected by a gear position sensor 39.

Further, the power generation ECU 6 or the engine ECU 7
Even when the power transmission line 24 is not connected to the power transmission line connection unit 25, the mode switching to the power generation mode described above is not performed. Whether or not the transmission line 24 is connected to the transmission line connection unit 25 is detected by a transmission line connection sensor 26. By doing so, safety during power generation can be more reliably ensured.

Further, as another method, without providing a mode changeover switch 18 or the like, the receiving pipe connecting portion 2 can be provided.
When the receiving pipe 21 is connected to the engine 2, the operation mode of the engine 2 may be automatically set to the power generation mode. Whether or not the receiving pipe 21 is connected to the receiving pipe connecting portion 22 may be detected by the receiving pipe connection sensor 23. Also in this case, it is preferable that the mode switching is not performed in the power generation ECU 6 when the parking brake is in the braking state and the gear position is not at the predetermined position.

Alternatively, when the transmission line 24 is connected to the transmission line connection portion 25 without providing such a mode changeover switch 18, the operation mode of the engine 2 is automatically set to the power generation mode. You may. Transmission line connection 2
Whether or not the transmission line 24 is connected to 5 may be detected by the transmission line connection sensor 26. Also in this case, the power generation ECU
6 is the parking brake is in the braking state, and
When the gear position is not at the predetermined position, it is preferable that mode switching is not performed.

Of course, the receiving pipe 2 to the receiving pipe connecting portion 22
The operation mode of the engine 2 may be set to the power generation mode side only when both the connection of the transmission line 1 and the connection of the transmission line 24 to the transmission line connection portion 25 are realized. Further, the connection of the heat transfer tube 27 to the heat transfer tube connection portion 28 is also detected by the heat transfer tube connection sensor 29, and the connection of the reception tube 21 to the reception tube connection portion 22 and the connection of the transmission line 24 to the transmission line connection portion 25 are performed. Connection and heat transfer pipe 2 to heat transfer pipe connection 28
Engine 2 only when all 7 connections are realized
May be set to the power generation mode.

After the above-described setting is completed, power generation by the vehicle 1 is started by a start switch (not shown) provided in the power receiving unit 44. In the present embodiment, the power generation start command from the start switch is transmitted to the vehicle 1 via the communication line 55. Vehicle 1
Upon receiving the power generation start command, the power generation ECU 6 and the engine ECU 7 start the engine 2 in cooperation with each other.
The start switch may be provided on the vehicle 1 side, or the start of the engine 2 itself may be directly performed by a human.

The engine 2 is operated in a power generation mode.
The generator 4 is driven by the output of the engine 2,
Power generation is performed.

To the engine 2, natural gas as a fuel for power generation is supplied from outside the vehicle 1 through a receiving pipe 21. As described above, when the fuel for power generation is supplied to the vehicle 1 from the outside, the fuel storage amount on the vehicle 1 side does not change. For this reason, when trying to drive the vehicle 1 after the power generation, it is unlikely that there is a shortage of gas. In addition, if power generation is attempted using the fuel mounted on the vehicle 1, the time during which power generation can be performed is limited. In this way, if the fuel for power generation is supplied from outside the vehicle 1, power generation can be performed for a long time without changing the fuel storage amount of the vehicle 1.

The vehicle 1 of this embodiment has a CNG compressor 43 in addition to the CNG tank 5. Therefore, the vehicle 1 can be refueled. This fuel supply may be performed during power generation, or may be performed using the receiving pipe 21 or the like when power is not being generated. Gas fuel such as natural gas, if not compressed, would increase the vehicle mounting capacity.
After compressing using, for example, the CNG tank 5, it can be stored in a space-efficient manner by storing it in the CNG tank 5.
When replenishing the natural gas to the CNG tank 5 at a gas station or the like, without using the CNG compressor 43,
The CNG compressed by the equipment on the gas station side may be directly supplied to the CNG tank 5.

Further, as in the present embodiment, gas fuel for power generation (here, natural gas which is city gas) is supplied from outside the vehicle 1, but this is a low-pressure gas fuel. The low-pressure gas fuel referred to here is a gas fuel that is not actively compressed at the temperature. in this way,
By supplying the low-pressure gas fuel from the outside, the trouble of decompressing the high-pressure gas is eliminated, and power generation can be performed efficiently. For example, when the vehicle 1 is operated, the high-pressure gas fuel in the CNG tank 5 is used after being decompressed. In this case, it is necessary to drive a decompression valve or the like, which requires extra energy.

In the power generation mode of the engine 2, natural gas is supplied to the engine 2 via the low-pressure fuel supply system 41. In the low-pressure fuel supply system 41, natural gas is supplied using a negative pressure of an intake pipe by a carburetor or the like. When power is generated in the vehicle 1, the engine 2 is driven, and the generator 4 generates power using the driving force. At this time, engine 2
It is preferable to operate constantly in the region with the highest energy efficiency. Further, at this time, the engine 2 is not constantly operated at a high load, but is operated constantly in a rather low load region. In such a case, highly accurate fuel injection by the injector 9 or the like is not necessary. Rather, when fuel is supplied using the injector 9, energy is required for driving the injector 9.

On the other hand, the engine 2 is required to have high responsiveness so that the driver can perform acceleration and deceleration when the vehicle 1 is operated, not when the vehicle is stopped but when power is generated. In such a case, the engine 2 is required to have various outputs from a low load to a high load, from a steady load to a transient load. In such a case, fine fuel injection control is performed using the injector 9 to cope with any output demand. As described above, by making the method of supplying fuel to the engine 2 different between power generation and operation,
While the most efficient operation is performed during power generation, the operation that satisfies the performance required as a vehicle can be performed during operation.

The generator according to the present embodiment is a three-phase AC generator, and generates AC power. The generated power is used as the AC power, as the transmission line 24 and the power receiving unit 4.
The electric power is transmitted to the house 30 via the communication line 4. The house 30 converts the received AC power into 100V for home use. As described above, it is preferable to generate AC power and transmit it as AC power, because power transmission can be facilitated and power transmission efficiency can be improved. Also, when power is transmitted using electromagnetic induction, it is preferable to generate AC power and transmit it as AC power, as described above.
In addition, you may transmit to the house 30 side as DC power using the inverter of the vehicle 1 side.

Further, in the present embodiment, as described above, the heat generated by the engine 2 during power generation is supplied to the house 30 via the heat transfer pipe 27. On the house 30 side, this heat is effectively used.

If an abnormality is detected during power generation or power transmission, safety measures are taken. The abnormality detection is determined by the power generation ECU 6 based on the outputs of the various sensors. That is, these various sensors and the power generation ECU 6 function as safety measure execution means. Hereinafter, some specific examples of these safety measures will be described.

First, the first safety measure is that when the movement of the vehicle 1 is detected during power generation or power transmission, the power generation ECU 6 stops power generation or power transmission. The movement of vehicle 1
It can be detected by the wheel speed sensor 35. Normally, the vehicle 1 does not move during power generation or power transmission. The receiving pipe 21 and the transmission line 24 are connected to the vehicle 1, and it is dangerous that the vehicle 1 moves during power generation or power transmission. Therefore, when the movement of the vehicle 1 is detected during power generation or power transmission, the power generation ECU 6 stops power generation or power transmission.

The next safety measure is that during power generation or transmission,
The door of the vehicle 1 is locked by the power generation ECU 6. The door may be locked at least during power generation or power transmission, and the door may be locked at the same time that the control mode of the engine 2 is switched to the power generation mode. Further, power generation may be automatically started after the door is locked.

The door is locked by controlling the door lock 32 via the door ECU 31 based on a command from the power generation ECU 6. This makes it impossible to get on the vehicle 1 during power generation or power transmission, so that power generation or power transmission can be safely continued. During power generation or transmission, the vehicle 1
If it becomes necessary to open the door, it is convenient to set a method of unlocking the door without stopping power generation or power transmission according to a specific procedure.

Alternatively, as described above, instead of locking the door during power generation or power transmission, power generation or power transmission may be stopped when the door is opened during power generation or power transmission. Whether the door is opened or not is determined by door ECU3
1 detected by the door opening / closing sensor 33 via the power generation EC
Power generation or transmission is stopped by U6. By doing so, if one forgets that power is being generated or transmitted, or if one gets on the vehicle 1 without knowing and intends to use the vehicle 1 for purposes other than power generation or power transmission, It can be stopped automatically, improving usability.

The next safety measure is to stop power generation or power transmission when a predetermined vibration is applied to the vehicle 1 during power generation or power transmission. The situation in which vibration is applied to the vehicle 1 may be, for example, when an earthquake occurs or when something collides with a stopped vehicle. The vibration applied to the vehicle 1 is detected by the G sensor 36 and the yaw rate sensor 37, and when it is determined that the detected vibration is equal to or higher than a predetermined level, the power generation ECU 6 stops power generation or power transmission. When vibration is applied to the vehicle 1 such as during an earthquake, it is preferable to stop power generation or power transmission in order to prevent a secondary disaster.

The next safety measure is to stop power generation or power transmission when the ambient temperature of the vehicle 1 during power generation or power transmission becomes equal to or higher than a predetermined temperature. A situation in which the ambient temperature of the vehicle 1 is equal to or higher than the predetermined temperature may be a fire or the like. The ambient temperature of the vehicle 1 is detected by the intake air temperature sensor 11, and when it is determined that the detected temperature is equal to or higher than the predetermined temperature, the power generation ECU 6 stops power generation or power transmission.
In a fire or the like, it is preferable to stop power generation or transmission from the viewpoint of preventing a secondary disaster. In addition, to detect the ambient temperature,
An outside air temperature sensor of an air conditioner may be used.

As another safety measure, the operation state of the engine is detected by various sensors 8 to 15, and if it is determined that an abnormality has occurred in the engine 2, the power generation ECU
It is also conceivable that 6 stops power generation or transmission.

The main body of the vehicle 1 and the power receiving unit 44 are respectively provided with transceivers (power transmitting means, receiving means, communication means) 53,
54. By exchanging information about power generation between these, while efficiently generating power,
Power generation can be reliably controlled.

The information on power generation exchanged between the transceivers 53 and 54 includes, for example, information on power transmitted from the vehicle 1 to the power receiving unit 44.
As described above, by transmitting the information regarding the power to be transmitted from the vehicle 1 to the power receiving unit 44, the transmitted power can be efficiently consumed on the power receiving unit 44 side, that is, on the house 30 side. In addition, the house can change the power generation status of the vehicle 1 based on the received information. For example, if the power is surplus, the information may be transmitted to the vehicle 1 so as to save the power generation, and if the power is insufficient, the vehicle may be generated to generate more power. The information may be sent to one side. On the vehicle 1 side, the power generation ECU 6 controls power generation based on these pieces of information transmitted from the power receiving unit 44.

As other information related to power generation exchanged between the transceivers 53 and 54, there is information related to fuel for power generation supplied to the vehicle 1. For example, when the vehicle 1 attempts to generate more power, the power receiving unit 44 supplies more power for generating power.
It is possible to issue a command to the side. The power receiving unit 44 receiving such a command operates the fuel valve 47 by the power receiving ECU 45 to supply more power generation fuel to the vehicle 1.

On the contrary, on the power receiving unit 44 side,
If more power is desired, a command to supply more fuel for power generation can be issued to the vehicle 1 side. The power generation ECU 6 of the vehicle 1 receiving such a command generates more electric power by using the supplied power generation fuel. Alternatively, when the power generation is stopped on the vehicle 1 side, the vehicle 1
The power transmission unit 44 may transmit a command to stop the supply of the fuel for power generation from the side, and in response thereto, the power receiving unit 44 may stop the supply of the fuel. At this time, if the fuel valve 47 is closed first and the fuel for power generation in the receiving pipe 21 is used up, even if the receiving pipe 21 is removed from the vehicle 1 after the power generation is completed, the fuel for power generation remains inside the receiving pipe 21. It is preferable because it is not performed.

Further, it is possible to control the power generation in the vehicle 1 from the power receiving unit 44 side. In this case, the control command from the power receiving unit 44 is transmitted to the power generation ECU 6 via the transceivers 54 and 53. The power generation ECU 6 generates power based on the transmitted control command. Thus, the start and stop (emergency stop) of power generation can be remotely controlled from the power receiving unit 44 side. The power receiving unit 44 can also monitor the power generation status on the power receiving unit 44 side by receiving the power generation status transmitted from the vehicle 1. When the power receiving unit 44 receives the information indicating that the power generation state is abnormal, the power receiving unit 44 turns on or blinks the warning lamp 52 or sounds a buzzer to call attention to a person in the house 30.

Further, as a case where there is an abnormality in the power generation situation, for example, there is a case where a leak occurs at any point.
One method for detecting an electric leakage is as follows. On the vehicle 1 body side, the power generation amount is actually grasped by the power generation ECU 6. On the other hand, on the power receiving unit 44 side,
The actually received power amount is grasped by the power receiving ECU 45. Then, these power amounts are transmitted and received by the transceivers 53 and 54, and the power generation ECU 6 or the power receiving ECU 45 compares the balances. If the difference between the balances is within an allowable range (a certain amount of loss cannot be avoided during power transmission, so a certain amount of balance difference occurs), it can be determined that there is no leakage. On the other hand, if the balance difference is large, it can be determined that electric leakage has occurred at any point. In such a case, the power receiving unit 44 turns on or blinks the warning lamp 52 or sounds a buzzer, and the power generation ECU 6 stops power generation and power transmission.

The power generation by the vehicle 1 may be controlled by a timer using the power generation ECU 6 and / or the power reception ECU 45.
When the vehicle 1 generates electric power, the engine 2 is driven, so that noise is generated. For this reason, a timer may be set so that power generation is not performed at night, and power generation may be stopped at a predetermined time. Further, by diverting the power generation system, it becomes possible to perform the warm-up operation of the engine 2 when a predetermined time has elapsed in the early morning when the outside air temperature is low.

Although the above description is only related to the electric power, in the present embodiment, the heat is also transferred to the house 3 through the heat transfer pipe 27.
Since the information is supplied to the 0 side, information relating to this is also exchanged by the transceivers 53 and 54, and efficient control is performed.

Next, a second embodiment of the vehicle of the present invention will be described with reference to the drawings. The vehicle of the present embodiment also

The gasoline in the gasoline tank 105 is filled with the injector 9
Accordingly, the fuel is injected into an intake port (or in a cylinder) and supplied to the engine 2.

As described above, the type of fuel supplied to the engine 2 differs between when the vehicle is running and when the vehicle is stopped. As described above, by using different types of fuels and selectively using fuels (fuel for power generation and fuel for traveling) in each situation, the engine 2

Further, the vehicle 201 of the present embodiment generates electric power by the fuel cell 102, and thus does not generate much heat unlike an engine. For this reason, the vehicle 201 of the present embodiment
The vehicle 1 differs from the vehicle 1 of the above-described first embodiment also in that it does not have a mechanism for supplying heat to the outside.

However, most of the other structure of the vehicle 201 of the present embodiment is almost the same as the vehicle 1 shown in FIG. 1 of the above-described first embodiment.
