Abstract
A hybrid drive system including a rotating electric machine; an input member drive-coupled to an internal combustion engine and the rotating electric machine; an output member drive-coupled to a wheel; a speed change device with a plurality of switchable shift speeds changes the rotational speed of the input member and transmits the changed rotational speed to the output member; and a control device that controls the rotating electric machine. The control device corrects the output torque of the rotating electric machine so as to cancel out a torque fluctuation of the input member that accompanies an initial explosion of the internal combustion engine; and, when the initial explosion of the internal combustion engine occurs during a shift operation of the speed change device, modifies the torque correction amount in a direction that suppresses a change in the rotational speed of the input member that advances the shift operation.
