1. A hybrid electric vehicle, comprising: an engine including an in-cylinder injection valve; a fuel supply device configured to supply fuel to the in-cylinder injection valve; a motor configured to generate power using power from the engine and output power for running; a power storage device configured to exchange power with the motor; and a controller programmed to control the engine, the fuel supply device, and the motor,
wherein when the vehicle is stopped and removal of deposits from the in-cylinder injection valve is not required, and forced charging of the power storage device with load operation of the engine is not being performed, the controller is programmed to control the fuel supply device so that a supply fuel pressure, which is the pressure of the fuel supplied to the in-cylinder injection valve, is at a first fuel pressure,
when the vehicle is stopped and the removal of the deposits is required, and the forced charging of the power storage device is being performed, the controller is programmed to control the fuel supply device so that the supply fuel pressure is at a second fuel pressure higher than the first fuel pressure, and
when the vehicle is stopped and the removal of the deposits is required, and the forced charging of the power storage device is not being performed, the controller is programmed to control the fuel supply device so that the supply fuel pressure is at a third fuel pressure higher than the first fuel pressure and lower than the second fuel pressure.
