By the way, if the engine is operated for a long time while the vehicle is stopped in a place where ventilation is difficult such as in a garage or indoors, there is a possibility that the exhaust gas fills the periphery of the vehicle. Therefore, it is required to equip an auto shut-off device that automatically stops the engine after a predetermined time elapses when the vehicle is parked and stopped and the engine is operated.
However, in a vehicle that can supply electric power to the outside of the vehicle, if the auto shut-off device that automatically stops the engine in the parked / stopped state as described above is equipped, the electric power is continuously supplied to the outside for a long time. There was a problem that it became impossible and the usability was lowered.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a vehicle having excellent usability by being able to continuously supply electric power to the outside of the vehicle.

In order to achieve the above object, the vehicle control device of the present invention includes a storage battery, an engine, a generator driven by the engine to generate electricity, the storage battery, and a power extraction unit that outputs power from the generator to the outside of the vehicle. An engine automatic stop unit that automatically stops the engine when the engine is continuously operated for a first predetermined time or longer in a running stop state of the vehicle. When the power is output from the power extraction unit, the engine is provided with a power supply control unit for disabling the automatic engine stop by the engine automatic stop unit.

This makes it possible to continuously operate the engine for a first predetermined time or longer when the electric power is output from the electric power extraction unit. Therefore, it becomes possible to continuously output electric power from the electric power extraction unit for a first predetermined time or longer.
It is preferable to include a notification unit for notifying the invalidation of the automatic engine stop by the power supply control unit.

As a result, the user of the vehicle is notified of the invalidation of the automatic engine stop, so that the user can be informed and warned that the engine will continue to operate in the parked / stopped state.
Preferably, the automatic stop invalidation confirmation operation unit for confirming the invalidation of the automatic stop of the engine is provided, and the power supply control unit is operated to confirm the invalidation of the automatic engine stop by the automatic stop invalidation confirmation operation unit. It is advisable to allow the engine automatic stop unit to invalidate the engine automatic stop only when the engine automatic stop is performed.

This makes it possible to prevent the automatic engine stop from being disabled without the user's recognition when the electric power is output from the electric power extraction unit.
Preferably, the power supply control unit is for automatically stopping the engine by the automatic stop invalidation confirmation operation unit until a second predetermined time elapses after the notification unit notifies the invalidation of the automatic stop of the engine. If the invalidation confirmation operation has not been performed, the engine automatic stop by the engine automatic stop unit may be executed.

As a result, if the confirmation operation for disabling the automatic engine stop is not performed by the time when the second predetermined time elapses after the notification of the invalidation of the automatic engine stop is performed, the automatic engine stop is executed. The operation of the engine in the parked / stopped state for the first predetermined time or longer is restricted.
Preferably, the confirmation operation storage unit for storing the confirmation operation by the automatic stop invalidation confirmation operation unit is provided, and the power supply control unit is stored in the confirmation operation storage unit when the power is output from the power extraction unit. It is advisable to determine whether the automatic engine stop is enabled or disabled based on the confirmation operation information.

As a result, it is not necessary to perform the confirmation operation of disabling the automatic engine stop every time when the electric power is output from the power extraction unit, and the trouble of the confirmation operation can be saved.
Preferably, the confirmation operation storage unit may erase the storage of the confirmation operation information when the power of the vehicle is turned off.
As a result, when the power is turned on from the power-off state of the vehicle and the power is output from the power extraction unit, a confirmation operation by the automatic stop invalidation confirmation operation unit is required. Therefore, it is possible to prevent the automatic engine stop from being disabled without the user's knowledge, for example, when the user has parked for a long period of time and forgot to perform the confirmation operation last time, or when the user has replaced another user. can.

Preferably, the power supply control unit is permitted to invalidate the automatic engine stop only when a predetermined invalidation permission condition is satisfied.
As a result, the automatic engine stop is not invalidated when the invalidation permission condition is not satisfied, and the automatic engine stop can be appropriately invalidated.

According to the vehicle travel control device of the present invention, the automatic engine stop by the engine automatic stop unit is invalidated when the electric power is output from the power extraction unit, so that the engine does not automatically stop when the vehicle is stopped. Then the engine can be operated. Therefore, it is possible to continuously output electric power to the outside of the vehicle for a long time, and it is possible to supply power to the outside of the vehicle with excellent usability.

The electric power generated by the generator 9 can charge the storage battery 11 via the front inverter 10 and can supply electric power to the front motor 4 and the rear motor 6.
The storage battery 11 is composed of a secondary battery such as a lithium ion battery, and has a battery module (not shown) composed of a plurality of battery cells collectively. Further, the storage battery 11 includes a battery management unit 11a that monitors the state of the battery module such as the voltage and temperature of the battery module.

The front inverter 10 controls the output of the front motor 4 based on the control signal from the hybrid ECU (Electronic Control Unit) 20 described later, and also controls the output (generated power) of the generator 9 based on the control signal from the hybrid ECU 20. Has the function of
The rear inverter 12 has a function of controlling the output of the rear motor 6 based on the control signal from the hybrid ECU 20.

The vehicle 1 is provided with a charger 21 that charges the storage battery 11 with an external power source, and an engine ECU 22 that drives and controls the engine 2.
Further, for example, a power outlet 30 (power extraction unit) is provided in the luggage compartment or the rear of the vehicle 1. The power outlet 30 can output electric power transformed from the storage battery 11 and the generator 9 to, for example, AC 100V via the transformer 31. The operation of the transformer 31 is controlled by the power supply ECU 32 (power supply control unit), and the output or stop of the output of the power from the power outlet 30 is controlled.

An AC supply SW33 is provided in the vicinity of the driver's seat of the vehicle 1 or in the vicinity of the power outlet 30. The AC supply SW 33 is a switch for switching whether or not power can be output from the power outlet 30. The AC supply SW33 maintains a state in which electric power can be output by operating the vehicle 1 when the power is turned on. For example, the AC supply SW33 is provided with an indicator lamp such as an LED to indicate that the power outlet 30 is in a state where power can be output. The holding of the power output ready state is reset to the power output impossible state by re-operating the AC supply SW33 or turning off the vehicle power.

FIG. 2 is a configuration diagram of the engine automatic stop control system 40 (control device) of the vehicle 1 of the present embodiment.
The engine automatic stop control system 40 of the present embodiment includes a power supply ECU 32, a hybrid ECU 20, and a meter 34 (notification unit).
The hybrid ECU 20 is a comprehensive control device for controlling the running of the vehicle 1, and includes an input / output device, a storage device (ROM, RAM, non-volatile RAM, etc.), a central processing unit (CPU), a timer, and the like. It is configured. Further, the engine ECU 22 and the power supply ECU 32 are also configured to include an input / output device, a storage device (ROM, RAM, non-volatile RAM, etc.), a central processing unit (CPU), a timer, and the like.

The operation information of the AC supply SW33 is input to the hybrid ECU 20. Further, the operation information (current shift position) of the shift lever is input to the hybrid ECU 33 by the shift SW35 or the like.
The meter 34 is a display device installed on, for example, the dashboard of the vehicle 1, and can display various information to the driver and operate with a touch panel.

The hybrid ECU 20, the power supply ECU 32, and the meter 34 are connected by a CAN so that various control and operation information can be exchanged with each other.
Further, like the power supply ECU 32 and the hybrid ECU 20, various ECUs of the vehicle 1 can exchange power on / off information (IG switch operation information) of the vehicle 1.
The power supply ECU 32 includes an engine automatic stop unit 32a that executes an auto shut-off function.

The auto shut-off function is a function for suppressing the filling of exhaust gas around the vehicle 1, and the engine 2 continues to operate for the first predetermined time t1 or more when the vehicle 1 is powered on and the vehicle is stopped. In this case, the engine 2 is automatically stopped via the hybrid ECU 20 and the engine ECU 22. The power supply ECU 32 may determine that the vehicle 1 is in the stopped state by, for example, the shift position input via the hybrid ECU 20 being the parking (P) position. The first predetermined time t1 may be set to, for example, several minutes to several tens of minutes. The first predetermined time t1 may be arbitrarily changed by a switch or the like displayed on the meter 34.

Next, the invalidation control of the auto shutoff function will be described.
When the AC supply SW 33 is operated when the vehicle power is turned on (IG-ON), the power supply ECU 32 causes the meter 34 to notify the meter 34 that the auto shut-off function is invalidated (regulated) by displaying characters or the like. Notification of invalidation of the auto shut-off function may be further performed by voice. Further, the meter 34 displays a confirmation switch 34a (automatic stop invalidation confirmation operation unit) for confirming the invalidation of the auto shutoff function as well as displaying the invalidation of the auto shutoff function. The meter 34 may display, for example, a switch displaying OK or the like as the confirmation switch 34a.

The power supply ECU 32 starts the operation of the timer 32b at the same time as the start of the notification of the invalidation of the auto shutoff function. Then, if the confirmation switch 34a is operated by the time when the second predetermined time t2 elapses from the start of the operation of the timer 32b, the auto-shut-off function is disabled. That is, when the AC supply SW33 is in the ON state, the power supply ECU 32 automatically operates the engine 2 even if the engine 2 continues to operate for the first predetermined time t1 or more when the vehicle 1 is parked / stopped (running stopped state). Do not stop the engine 2.

On the other hand, if the confirmation switch 34a is not operated by the second predetermined time t2 from the start of the notification of disabling the auto shutoff function, the power supply ECU 32 does not disable the auto shutoff function. Execute the auto shut-off function. That is, when the operation of the engine 2 continues for the first predetermined time t1 or more while the vehicle is stopped, the engine 2 is automatically stopped.

The meter 34 may display an operation switch for rejecting the disabling of the auto-shut-off function as well as a display of the confirmation switch 34a for disabling the auto-shut-off function. When the operation switch for refusing to disable the auto-shut-off function is operated, the auto-shut-off function is auto-shut off even before the second predetermined time t2 has elapsed from the start of the notification of the disabling of the auto-shut-off function. The function is executed.

It is preferable that the storage device of the power supply ECU 32 is provided with a storage unit 32c (confirmation operation storage unit) for storing the operation information (presence / absence of invalidation confirmation operation) of the confirmation switch 34a. The storage unit 32c stores the operation information of the confirmation switch 34a after the notification of the invalidation of the auto shutoff function as the confirmation operation information.
Then, in the vehicle power-on state, the storage unit 32c responds to the operation information of the previous confirmation switch 34a stored in the storage unit 32c without displaying the confirmation switch 34a when the AC supply SW33 is turned on next time. Then, it may be determined whether the auto shut-off function is enabled or disabled. The operation information of the confirmation switch 34a stored in the storage unit 32c is erased when the power is turned off (IG-OFF). Therefore, when the power is turned on after the power is turned off and the AC supply SW33 is turned on, it is necessary to display the confirmation switch 34a and confirm that the auto shut-off function is disabled.

As described above, in the present embodiment, when the AC supply SW33 is in the ON state, the auto shut-off function is disabled. That is, when the AC supply SW33 is in the ON state, the power supply ECU 32 automatically operates the engine 2 even if the engine 2 continues to operate for the first predetermined time t1 or more when the vehicle 1 is parked / stopped (running stopped state). Do not stop the engine 2.
As a result, when the electric power is output from the power outlet 30 of the vehicle 1, the engine can be continuously operated for the first predetermined time t1 or more, and the duration of the electric power output from the power outlet 30 can be extended. Can be done. Therefore, it is possible to supply electric power to the outside of the vehicle, which is easy to use.

Further, the power supply ECU 32 notifies the user such as the occupant of the vehicle 1 by displaying or by voice or the like that the auto shut-off function is disabled when the AC supply SW33 is in the power-on state of the vehicle 1. Therefore, it is possible to inform the user that the engine 2 will continue to operate and warn the user.
Further, when the confirmation switch 34a is operated after notifying that the auto shutoff function is disabled, the auto shutoff function is permitted to be disabled, so that when the AC supply SW33 is turned on. It is possible to prevent the auto shutoff function from being disabled without the user's knowledge.

Further, if the confirmation switch 34a is not operated by the lapse of the second predetermined time t2 after notifying that the auto shutoff function is disabled, the auto shutoff function is executed, for example. If the user forgets to operate the confirmation switch 34a, the auto shut-off function is executed, and the operation of the engine 2 for the first predetermined time t1 or more when the vehicle is parked or stopped is restricted.

Further, a storage unit 32c for storing the operation information of the confirmation switch 34a is provided, and when the AC supply SW33 is turned on, the auto shut is performed based on the previous operation information of the confirmation switch 34a stored in the storage unit 32c. Since it is determined to invalidate the off function, it is not necessary to operate the confirmation switch 34a every time the AC supply SW33 is turned on, and the trouble of the confirmation operation can be saved.

However, when the power of the vehicle 1 is turned off, the operation information of the confirmation switch 34a is erased from the storage unit 32c. Therefore, when the power of the vehicle 1 and the AC supply SW33 are turned on after that, the engine 2 is turned on. When it is necessary to continuously operate for the first predetermined time t1 or more, it is necessary to operate the confirmation switch 34a again. Therefore, for example, if the user has parked for a long period of time and forgot to operate the confirmation switch 34a last time, or if the user replaces another user, the auto-shut-off function is disabled without the user's knowledge. Can be prevented.

Further, the power supply ECU 32 may have an invalidation permission condition when the auto shut-off function by the operation of the AC supply SW33 is invalidated. Examples of the invalidation enable condition include the stop position environment of the vehicle 1, the surrounding atmospheric condition, and the charging status of the storage battery 11.
As the stop position environment of the vehicle 1, it is determined whether the vehicle 1 is located indoors or outdoors by the navigation system of the vehicle 1, and if it is indoors, the auto shutoff function cannot be disabled and outdoors. In some cases, it may be possible to disable the auto shut-off function. As a result, it is possible to prevent the auto-shut-off function from being invalidated indoors and prevent the exhaust from being filled indoors.

As for the surrounding atmospheric conditions, a sensor for detecting exhaust components such as carbon monoxide is provided in the vehicle 1, and the auto-shut-off function is disabled when the exhaust components in the atmosphere around the vehicle 1 are in a predetermined ratio or more. It may be possible to disable the auto-shut-off function when the ratio is less than the predetermined ratio. Further, when the engine 2 is operated and the electric power is supplied from the power outlet 30, if the exhaust component in the atmosphere around the vehicle 1 becomes a predetermined ratio or more, the engine 2 is stopped at that time. It is good to control it like this. This makes it possible to prevent the exhaust gas from filling the atmosphere around the vehicle 1.

As for the charging status of the storage battery 11, the charging rate of the storage battery 11 is input from the battery management unit 11a, and when the charging rate is equal to or higher than the predetermined charging rate, the auto shutoff function cannot be disabled and the charging rate is lower than the predetermined charging rate. It is only necessary to enable the auto-shut-off function to be disabled. As a result, when the demand for power generation is low, such as when the charge rate is equal to or higher than a predetermined charge rate, the auto shut-off function is not disabled, so that the engine 2 can be prevented from operating for a long time when the vehicle is stopped.

This is the end of the description of the present invention, but the present invention is not limited to the above embodiment.
For example, in the above embodiment, the hybrid ECU 20 that comprehensively controls the drive system of the vehicle 1 and the power supply ECU 32 that performs the auto shut-off function and its invalidation control are separate, but the hybrid ECU 20 and other control units are used. May be integrated.
Further, although the vehicle 1 of the above embodiment is a four-wheel drive plug-in hybrid vehicle, the present invention may be applied to a two-wheel drive vehicle or a hybrid vehicle that is not a plug-in type.

Further, the vehicle 1 of the above embodiment is a parallel hybrid vehicle capable of driving the front wheels 3 by the engine 2, but may be a series hybrid vehicle. The present invention can be widely applied to a vehicle equipped with an engine for driving a generator and capable of supplying electric power to the outside.
