A hybrid vehicle includes a forward-backward travel changeover mechanism including a forward clutch and a reverse brake, a continuously variable transmission, an engine, a motor generator, an output clutch, a mechanical oil pump, an electric oil pump, a manual valve, an oil passage, and a control unit. The manual valve supplies oil to the forward clutch when a parking range is selected. When a state of charge of a high voltage battery decreases to a predetermined value or lower in the parking range, the control unit disengages the output clutch, engages the forward clutch, and causes the engine to operate to drive the motor generator as a generator. When a backward traveling range is selected while power generation is being performed in the parking range, the control unit drives the electric oil pump, and supplies the oil to the output clutch or the reverse brake through the oil passage.
