A hybrid vehicle can travel using outputs from an engine and a second motor-generator. A first motor-generator can generate electric power for charging a plurality of DC power supplies using the output from the engine during vehicle traveling or during a vehicle stop. A power supply system includes a power converter connected across the DC power supplies and an electric power line connected in common to the first and second motor-generators. A control device generates operation commands for the first and second motor-generators and the engine so as to ensure driving request power based on a vehicle traveling condition and charging/discharging request power for the DC power supplies as a whole. The setting of the charging/discharging request power is switched in accordance with an operation mode of the power converter.
