Patent ID: 8052570

Claim:
A control device for a vehicular power transmitting apparatus wherein the vehicular power transmitting apparatus includes (i) an electric differential portion in which, by controlling an operational state of an electric motor connected to a rotary element of a differential mechanism in a power transmissive state, a differential state between a rotation speed of an input shaft to which an internal combustion engine is connected and a rotation speed of an output shaft is controlled; and (ii) a differential state limiting device that mechanically limits a differential state of the electric differential portion; the control device is comprised of an engine-stop controlling portion that decreases a rotation speed of the internal combustion engine by the electric motor upon stopping the internal combustion engine, the engine-stop controlling portion limiting a differential state of the electric differential portion by the differential state limiting device when the operational state of the electric motor is limited; the differential state limiting device includes a first limiting device that limits the rotation of one rotary element forming the differential mechanism and a second limiting device that limits relative rotations between two rotary elements forming the differential mechanism; and the engine-stop controlling portion limits the differential state of the electric differential portion by simultaneously using a first differential limiting action by the first limiting device and a second differential limiting action by the second limiting device.
