Hybrid drive device

A rotation speed controller performs a rotation speed control to allow the rotation speed of a first rotating electrical machine to be equal to a start up target value, when an internal combustion engine is started while a frictional engagement device is disengaged. An engagement controller controls a non-synchronization engagement of the frictional engagement device and allows the frictional engagement device to be in a direct engagement state when performing the rotation speed control. A start up instruction unit gives a start up instruction with respect to the internal combustion engine on condition of being directly engaged. The rotation speed controller sets the start up target value so that a rotation speed at the time of a direct connection, which is a rotation speed of the engine while in direct engagement, becomes a start up rotation speed that is set within a startable rotation speed range of the engine.

Driving device for vehicle

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.
