摘要： A hybrid vehicle is equipped with an engine that is connected to a power split mechanism, a generator, an electric motor, and also a stepped transmission that is arranged between the electric motor and a drive shaft. An electronic control unit (an ECU) with which this hybrid vehicle is equipped revises a down line downward to make a downshift likely to occur when at least one of a prescribed generator condition and a prescribed electric motor condition is fulfilled. The generator condition includes that the temperature of the generator is equal to or higher than a first reference temperature and that an absolute value of a rotational speed of the generator decreases due to the making of the downshift. The electric motor condition includes that the temperature of the electric motor is equal to or higher than a third reference temperature.
