Hybrid drive system

摘要

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.

1. A hybrid drive system comprising:
a rotating electric machine; an input member that is drive-coupled to an internal combustion engine and the rotating electric machine; an output member that is drive-coupled to a wheel; a speed change device that has a plurality of switchable shift speeds, and changes the rotational speed of the input member at a speed ratio of the respective shift speeds and transmits the changed rotational speed to the output member; and a control device that at least performs an operation control for the rotating electric machine, wherein the control device includes a first torque correction section that 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 a second torque correction section that, when the initial explosion of the internal combustion engine occurs during a shift operation of the speed change device, modifies the torque correction amount set by the first torque correction section in a direction that suppresses a change in the rotational speed of the input member that advances the shift operation.
