Abstract:
A vehicle drive device includes an input coupled to an internal combustion engine; an output coupled to wheels; first and second rotary electric machines; a differential including at least three rotary elements; a control; and an engagement device. The control determines, when engine stop conditions are established while the engagement device is drivably connected, the engine is operating, and the output member is rotating, whether rotation of the first electric machine when stop conditions are established is opposite to rotation of the first electric machine when rotation of the engine stops; executes torque control where the first electric machine outputs torque to reduce the rotational speed of the engine when the stop establishing rotational direction is opposite to the subject rotational direction; and issues a command to release the drivable connection when the rotational speed of the first electric machine falls within a rotational speed range that includes zero.
