<P>PROBLEM TO BE SOLVED: To provide a controller reducing possibility that comfort in time of traveling is impaired, in a power transmission device suitably used in a hybrid vehicle. <P>SOLUTION: In feedback control of a first electric motor M1, though responsiveness of first electric motor feedback torque TF<SB>M1</SB>becomes lower, and an its fluctuation becomes gentler as a feedback gain KP of the feedback control of the first electric motor M1 becomes smaller, a feedback gain change means 74 reduces the feedback gain KP in the feedback control as a gear change ratio γ<SB>AT</SB>of an automatic transmission part 20 becomes larger, during no gear change of the automatic transmission part 20. Accordingly, the fluctuation of the first electric motor feedback torque TF<SB>M1</SB>becomes gentle in the feedback control as the gear change ratio γ<SB>AT</SB>of the automatic transmission part 20 becomes large, and the fluctuation of the first electric motor feedback TF<SB>M1</SB>is more largely amplified and becomes easy to be transmitted to driving wheels 38. As a result, the possibility that the comfort at time of the vehicle traveling is impaired can be reduced. <P>COPYRIGHT: (C)2010,JPO&INPIT |
