Abstract
During a predetermined drive in which a hybrid vehicle is driven with shutting off gates of a first inverter and a second inverter and operating an engine, the hybrid vehicle controls the engine and a step-up/down converter, such that a reverse voltage of a first motor is higher than a voltage of a high voltage-side power line. In the event of an increase in an operation amount of an accelerator during the predetermined drive, the hybrid vehicle controls the engine and the step-up/down converter to limit an increment of a difference between the reverse voltage of the first motor and the voltage of the high voltage-side power line when a temperature of the step-up/down converter is equal to or higher than a predetermined temperature, compared with an increment of the difference when the temperature of the step-up/down converter is lower than the predetermined temperature.
