## Abstract

A vehicle includes an engine and a battery, and is configured to perform external power feeding of supplying electric power to the outside of the vehicle. The vehicle includes an MG that generates electric power by using motive power of the engine, and an ECU that controls the engine and the MG. When an outside air temperature is below a reference temperature and an amount of remaining fuel of the engine is below a reference amount in a case where the external power feeding is to be performed, the ECU limits the driving of the engine.

## Claims

### Claim 1

A hybrid vehicle including an internal combustion engine and a power storage device, and being configured to perform external power feeding of supplying electric power to the outside of the vehicle, said hybrid vehicle comprising:
a power generator that generates electric power by using motive power of said internal combustion engine; and
a control device that controls said internal combustion engine and said power generator,
said control device limiting driving of said internal combustion engine when an outside air temperature is below a reference temperature and an amount of remaining fuel of said internal combustion engine is below a reference amount in a case where said external power feeding is to be performed.

### Claim 2 (depends on 1)

The hybrid vehicle according to claim 1, further comprising a heating device that heats an interior of the vehicle by using heat generated during the driving of said internal combustion engine, wherein
said reference amount is set such that said interior of the vehicle can be heated by said heating device after said external power feeding has been performed.

### Claim 3 (depends on 1)

The hybrid vehicle according to claim 1, wherein
said reference amount is set such that said reference amount increases with decrease in said outside air temperature.

### Claim 4 (depends on 1)

The hybrid vehicle according to claim 1, wherein
said reference amount is set such that said reference amount increases with increase in travel distance from a position of said hybrid vehicle at the time of execution of said external power feeding to a fueling facility.

### Claim 5 (depends on 4)

The hybrid vehicle according to claim 4, further comprising a car navigation system configured to calculate a travel route from a current position of said hybrid vehicle to a destination, wherein
said travel distance is calculated by means of said car navigation system.

### Claim 6

A method of controlling a hybrid vehicle, said hybrid vehicle including a power storage device, an internal combustion engine, and a power generator, said power generator generating electric power by using motive power of said internal combustion engine, said hybrid vehicle being configured to perform external power feeding of supplying electric power to the outside of the vehicle, said method comprising the steps of:
detecting an outside air temperature;
detecting an amount of remaining fuel of said internal combustion engine; and
limiting driving of said internal combustion engine when said outside air temperature is below a reference temperature and said amount of remaining fuel is below a reference amount in a case where said external power feeding is to be performed.
