Abstract:
During a hybrid drive, a hybrid vehicle sets an engine required power based on a driving required power and controls an engine to output the engine required power, while controlling a motor to drive the hybrid vehicle with the driving required power. When a catalyst temperature of an exhaust emission control device is equal to or lower than a predetermined temperature that requires warming up, in the state that an output upper limit power which a power storage device is allowed to output is equal to or larger than a predetermined power, the hybrid vehicle sets a power calculated by subtracting the output upper limit power from the driving required power, to the engine required power. In the state that the output upper limit power is smaller than the predetermined power, the hybrid vehicle sets the driving required power to the engine required power.
