1. A vehicle comprising:
a power storage device;
a rotary electric machine configured to receive supply of electric power from the power storage device and generate a drive force for driving the vehicle;
a power generation device, separate from the rotary electric machine, configured to generate electric power to be supplied to the power storage device;
a heat radiation unit configured to radiate exhaust heat from the rotary electric machine and the power generation device; and
an electronic control unit configured to control power generation by the power generation device so as to increase an amount of power generated by the power generation device when vehicle required power due to drive of the vehicle is smaller than predetermined power compared to when the vehicle required power is larger than the predetermined power, an amount of power generated by the rotary electric machine and the power generation device being equal to or less than allowable generated electric power calculated from an amount of heat that is able to be radiated by the heat radiation unit,
the electronic control unit further configured to:
calculate an exhaust heat amount of the vehicle,
calculate an extra heat radiation capacity of the heat radiation unit,
determine a power generation amount of the power generation device, and
calculate the allowable generated electric power based on the exhaust heat amount of the vehicle, the extra heat radiation capacity of the heat radiation unit, and the power generation amount of the power generation device.
