<P>PROBLEM TO BE SOLVED: To provide a controller of a power transmission device for vehicle, equipped with the first transmission part and the second transmission part, wherein shift shock is suitably suppressed in simultaneous shift in which the transmission gear ratio of the first transmission part and the transmission gear ratio of the second transmission part are shifted to opposite directions. <P>SOLUTION: In simultaneous shift for changing a transmission gear ratio as a whole by mutually shifting the transmission gear ratio of a differential section 11 and the transmission gear ratio of an automatic transmission part 20 to opposite directions, a torque-down control means 90 changes torque-down quantity under shift when shift is progressing only by the automatic transmission part 20 and when shift is progressing simultaneously by the differential section 11 and the automatic transmission part 20 so that shift shock is effectively reduced in simultaneous shift by properly changing torque-down quantity according to the progressing state of simultaneous shift. <P>COPYRIGHT: (C)2009,JPO&INPIT |
