<P>PROBLEM TO BE SOLVED: To suppress shock that may be generated when fuel injection to an internal combustion engine is restarted. <P>SOLUTION: In restoration from fuel cut, an engine speed Ne of an engine 22, which is restricted within a range of a rate value Nrt2 smaller than a rate value Nrt1 in fuel cut to be a target engine speed Ne*, is set as a control engine speed N* (S160-S180), and motoring of the engine 22 is performed at the set control engine speed N*, and torque commands Tm1*, Tm2* of motors MG1, MG2 are set so that request torque Tr* is output to a ring gear shaft 32a as a drive shaft, and a control is performed (S190-S230). Therefore, a rotational state of the engine 22 is stabilized to restart fuel injection to the engine 22, and shock along with abrupt change in speed of engine 22 that may generated in the restart of the fuel injection is suppressed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
