<P>PROBLEM TO BE SOLVED: To maintain a target engine rotation speed regardless of a charge-discharge balance when changing gear of a mechanical transmission mechanism in a vehicular power transmission device including an electrical transmission mechanism and the mechanical transmission mechanism. <P>SOLUTION: Because an engine torque correction control for changing an engine torque Te corresponding to an amount of a torque added to an engine shaft by the change of an MG2 rotational speed Nm accompanying a gear change of an automatic transmission 18 is performed during an inertia phase of the gear change of the automatic transmission 18, the control of suppressing a divergence between an actual engine rotation speed Ne and the target engine rotation speed Ne* due to the gear change of the automatic transmission 18 can be performed without changing the charge-discharge balance by counterbalancing the torque generated at the engine shaft due to the change in the MG2 rotational speed Nm on a side of an engine 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
