<P>PROBLEM TO BE SOLVED: To provide a controller of a power transmission device, which suppresses reduction in regeneration efficiency, and reduces shift shock at the shift of a stepped shift mechanism in regeneration mode. <P>SOLUTION: A controller 100 of a power transmission device 10 is equipped with a differential part 11 having electric motors M1 and M2 which can be regenerated through an automatic shift part 20. When the automatic shift part 20 is shifted while the electric motor in the differential part 11 is regenerated, the shift is advanced under hydraulic control before the end of shift, and input axis rotating speed N<SB>IN</SB>of the automatic shift part 20 is controlled by at least one of the second electric motor M2 and first electric motor M1 at the end of shift. <P>COPYRIGHT: (C)2010,JPO&INPIT |
