Zusammenfassung:	PROBLEM TO BE SOLVED: To escape from being stuck when a vehicle is stuck by outputting sufficient driving force, without charging an electric storage device by excessive electric power. SOLUTION: When the vehicle is stuck and a driver is demanding large torque (S120), all auxiliary machines not affecting traveling are forcibly driven (S150), an input limit Win of a battery is enlarged for just a portion of excessive electric power Pove set on the basis of an accelerator opening Acc, a vehicle speed change ΔV, and a battery temperature Tb (S160-S180), carrier frequencies of an inverter and a booster converter are raised than normal (S200), and an engine and motors MG1, MG2 are controlled within a range of the enlarged input limit Win (S260-S310). By this, large torque is outputted to escape from being stuck without charging the battery by excessive electric power. COPYRIGHT: (C)2007,JPO&INPIT
