<P>PROBLEM TO BE SOLVED: To effectively suppress any sense of incompatibility due to such any abnormal sound as a muffle noise or a gear rattling sound to be generated according to the operation of a power output device. <P>SOLUTION: In a hybrid car 20, when an effective motor torque Tm2eff based on a value calculated by subtracting a brake drag torque Td at a transmission 60 side to a motor MG2 from the previous value of a torque command Tm2* showing the output torque of the motor MG2 is within a predetermined range including a value 0, the target operation point of an engine 22 based on a request torque Tr* is set by using a map fne(V) for setting a lower limit revolving speed (step S200), and the engine 22 is operated at the set target operation point, and the engine 22 and the motors MG1 and MG2 are controlled so that a power based on the request torque Tr* can be output to a ring gear shaft 32a as a driving shaft (steps S210 to S250). <P>COPYRIGHT: (C)2008,JPO&INPIT |
