1. A control device of a vehicle that controls the vehicle capable of traveling according to a plurality of traveling modes,
the plurality of traveling modes including:
a first traveling mode in which a driving wheel of the vehicle is capable of being driven by power output from an internal combustion engine and power output from an electric motor in accordance with electric power supplied from a power storage device; and
a second traveling mode in which the driving wheel is capable of being driven by the power output from the electric motor in accordance with electric power supplied from a generator that generates electric power using the power of the internal combustion engine,
the control device of a vehicle comprising:
a traveling mode control unit configured to
cause the vehicle to travel according to any one of the plurality of traveling modes,
derive an output of the power storage device based on inter-terminal voltage and output current of the power storage device, when the traveling mode of the vehicle is set to the first traveling mode, and
shift the traveling mode of the vehicle to the second traveling mode based on a comparison between the derived output of the power storage device and a predetermined transition threshold value,
wherein traveling mode control unit includes a threshold value setting unit configured to set the predetermined transition threshold value, and
wherein the threshold value setting unit is further configured to change a value of the predetermined transition threshold value in accordance with a maximum output of the power storage device derived based on the output of the power storage device.
