<P>PROBLEM TO BE SOLVED: To provide a controller for a vehicular drive unit, having a compact first electric motor while suppressing performance of the first electric motor or an engagement device from being reduced, when both the first electric motor and the engagement device operate to use a differential part as an electric differential device. <P>SOLUTION: A reaction force to engine torque T<SB>E</SB>can be received by the engagement device K0 all the time, and dependency on the first electric motor M1 for receiving the reaction force is reduced, since a torque sharing rate R<SB>T</SB>between a first electric motor reaction force torque T<SB>M1</SB>and an engagement device reaction force torque T<SB>K</SB>is changed based on required reaction power P<SB>S1</SB>, by a torque sharing rate changing means 82, when the differential part 11 is used as the electric differential device. A thermal load is distributed by the engagement device K0 and the first electric motor M1, to suppress a heat generation amount of the engagement device K0. The first electric motor M1 can be reduced in size while suppressing performance of the first electric motor M1 or the engagement device K0 from being reduced, as a result thereof. <P>COPYRIGHT: (C)2010,JPO&INPIT |
