Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent drop of power performance beforehand in a vehicle provided with an engine and a motor.SOLUTION: An ECU (200) determines that the load factor of a motor is 100% when motor detection temperature T is less than a load restriction starting temperature TR, and it decreases the load factor of the motor to less than 100% when it is not (220). The ECU calculates motor estimated temperature in the future (predetermined period later) by using NAVI information during EV travelling using motor power without engine power, and when the motor estimated temperature in the future is lower than the load restriction starting temperature TR, EV travelling inhibition temperature TP is set to "temperature T1" slightly lower than TR, and when it is not, EV travelling inhibition temperature TP is set to "temperature T2" lower than T1 (230). The ECU changes over to HV travelling using both powers of engine and motor when the motor detection temperature T exceeds TP during EV travelling.
