PROBLEM TO BE SOLVED: To provide a hybrid drive device which generates at least a part of an inertia torque during a speed change and can prevent uncomfortable feeling from occurring during the speed change.SOLUTION: A motor torque Tmg in an inertia phase from time t11 to time t13 during a power-on downshifting speed change, for example, is limited to a set value Tmg-lim that is set to or below a motor maximum torque Tmg-max after the speed change, and the engaged state of a releasing-side friction element is controlled so that an inertia torque calculated from a target input rotational speed is generated in an input-system member. During the speed change, the motor torque Tmg is prevented from fluctuating due to the fluctuation in the motor maximum torque Tmg-max that accompanies the change in rotation. The slope of a change in input rotational speed during the speed change is prevented from fluctuating, a drive force complying with the drive force requirements of a driver can be output, and uncomfortable feelings are prevented. |
