<P>PROBLEM TO BE SOLVED: To provide a control device for a vehicle power transmission device suitably reducing transmission shock in power-off upshifting in a vehicle power transmission device having an electric differential part and a transmission part. <P>SOLUTION: When a rotational speed N<SB>E</SB>of an engine 8 is reduced by a first motor M1 in power-off upshifting in an automatic transmission part 20, output power of the first motor M1 is reduced, since an engine rotation variation rate easing means 94 lowering a variation rate of the rotational speed N<SB>E</SB>of the engine 8 in comparison with that in a normal travel is provided. According to reduction in the output power, discharge capacity of an accumulator 56 is lowered, and for example, in torque-up control, output restriction of the accumulator 56 is prevented, so that torque-up quantity required by a second motor M2 can be secured, and consequently, transmission shock can be reduced. <P>COPYRIGHT: (C)2010,JPO&INPIT |
