<P>PROBLEM TO BE SOLVED: To provide a controller of a vehicle power transmission having an engine, an electric differential unit and a transmission unit, the controller reducing a shift shock at the transmission unit in engine fuel cut-off state. <P>SOLUTION: A downshift line changing means 88 changes the downshift line of an automatic transmission unit 20 to a lower-speed side in fuel cut-off of the engine 8, compared with in normal running. In fuel cut-off of the engine 8, a shift shock is likely to occur when the automatic transmission unit 20 is shifted; the downshift line changing means 88 changes the downshift line of the automatic transmission unit 20 to the lower speed side in fuel cut-off than that in normal running, to thereby suitably reduce a shift shock that occurs during gear shifting. <P>COPYRIGHT: (C)2010,JPO&INPIT |
