<P>PROBLEM TO BE SOLVED: To rotate an internal combustion engine at relatively high speed when a vehicle travels on a curved road, and to suppress the excessive rise of the temperature of an electric driving system including a motor. <P>SOLUTION: When traveling environment conditions are established, and the temperature of a motor, an invertor, and a booster circuit are less than prescribed temperature, a required power Pe* is output from an engine while the engine rotates at the number of revolutions obtained by restricting the temporary number of revolutions Netmp based on the required power Pe* and prescribed constraint by the lower limit number of revolutions Nemin, and the engine and two motors are controlled so that the required torque Tr* can be output to a driving shaft (S120 to S180, S200 to S260). When at least one of the temperatures of the motor, the invertor, and the booster circuit is equal to or more than the prescribed temperature, the required power Pe* is output from the engine while the engine rotates at the temporary number of revolutions Netmp, and the engine and the two motors are controlled so that the required torque Tr* can be output to the driving shaft (S120 to S160, S190 to S260). <P>COPYRIGHT: (C)2010,JPO&INPIT |
