<P>PROBLEM TO BE SOLVED: To compatibly suppress noise in a gear mechanism connected to an electric motor and to suppress reduction of operating efficiency of an internal combustion engine. <P>SOLUTION: When torque outputted from a second motor falls within a noise torque range if the engine and two motors are controlled so that the engine is operated at an efficiency priority operation point and requested torque Tr* is outputted to a drive shaft (S170), the engine and the two motors are controlled (S200 to S270) so that requested torque Tr* is outputted to the drive shaft and the engine is controlled at an operation point of lower rotation speed between a first tentative operation point (S180) obtained by using a noise suppression operation line and requested power Pe*, and a second tentative operation point (S190) to be set so that torque outputted from a second motor is larger than an upper limit of the noise torque range and the requested power Pe* is outputted from the engine. <P>COPYRIGHT: (C)2012,JPO&INPIT |
