<P>PROBLEM TO BE SOLVED: To provide a controller capable of restraining shift shocks when switching a power transmission train from a power transmission block state to a power transmission state in a vehicle drive mechanism having an automatic transmission between a differential mechanism functioned as a transmission mechanism by differential actions, a differential mechanism, and a drive shaft. <P>SOLUTION: When switching a shift operation system 46 from a non-drive position for selecting a power transmission block state to a drive position for selecting a power transmission state, a first clutch is engaged to switch the power transmission train to the power transmission state by an output control means 86, and output torque from a differential section 11 is controlled to gradually and continuously rise by using a first motor M1 and second motor M2 after its engagement. Thus, the output torque of the differential section 11 is controlled when a first clutch is engaged, and shift shocks is restrained even though hydraulic pressure of the first clutch is first applied. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
