<P>PROBLEM TO BE SOLVED: To stably operate an internal combustion engine outside a noise oscillation area in operating the internal combustion engine in the neighborhood of the noise oscillation area giving a feeling of displeasure to a driver or a crew due to a noise or oscillation. <P>SOLUTION: When an engine is operated on an NV line in applying a command power P* including a correction power Padj to an operation line Ld for execution, target rotational frequency Ne* is set by using a target engine power Pe* which does not include the correction power Padj, and target torque Te* is set by excluding the command power P* with the target rotational frequency Ne* (S200), and the engine and motors MG1 and MG2 are controlled so that the engine can be operated with the target rotational frequency Ne* and the target torque Te*, and that request torque Tr* can be output to driving wheels (S210 to S270). Thus, it is possible to precisely operate the engine on the operation line Ld for execution, and to suppress the engine from being operated in an area giving a feeling of displeasure or a feeling of incompatibility to a driver or a crew due to a noise or oscillation. <P>COPYRIGHT: (C)2011,JPO&INPIT |
