<P>PROBLEM TO BE SOLVED: To drive a vehicle at torque closer to torque required for traveling. <P>SOLUTION: A torsion angle θ of a damper computed by integrating a difference between engine speed Ne and the rotational frequency Nc of a carrier shaft serving as an input shaft is multiplied by the spring constant K of the damper to compute estimated torque Teest that is estimated to be actually outputted from the engine (S120-S130). A torque command Tm1* for a generator is set based on the estimated torque Teest so that the engine is operated at a desired engine speed Ne* (S160). Also, a torque command Tm2* for an electric motor is set so that the required torque Tr* is outputted to a drive shaft according to the set torque command Tm1* (S170-S190). The engine is operated at a desired operating point, and the engine, the generator and the electric motor are controlled so that the generator and the electric motor are driven at the torque commands Tm1*, Tm2*, respectively (S200). <P>COPYRIGHT: (C)2010,JPO&INPIT |
