Abstract:
A power transmission apparatus has a power distribution mechanism which is connected to an engine and a first motor-generator an in which at least three rotation elements enable to rotate in differential motions to one another, a power combining mechanism which is connected to the power distribution mechanism, a second motor-generator and an output shaft and in which four rotation elements enable to rotate in differential motions to one another, a brake mechanism which enables to selectively fix a rotation element of the power combining mechanism and a brake mechanism which enables to selectively fix a rotation element of the power combining mechanism which is connected to the engine.

Claim (Index 14):
A power transmission control method for the vehicle according to  claim 13 ,\n wherein the power transmission apparatus has at least a first power combining mode and a second power combining mode which have different driving force characteristics, and the method includes: a mode determination step of determining whether or not a present power combining mode is the first power combining mode; a speed determination step of determining whether or not a speed deviation which is a difference between a predetermined speed and a driving speed of the vehicle is equal to or smaller than a first threshold; a driving control step of controlling to drive at least the second electric motor in an event that it is determined in the mode determination step that the present power combining mode is the first power combining mode and that it is determined in the speed determination step that the speed deviation is equal to or smaller than the first threshold; a torque determination step of determining whether or not a torque applied to the rotation element which is fixed by the first fixing mechanism is equal to or smaller than a second threshold; and a shifting step of executing a shift from the first power combining mode to the second power combining mode by releasing the rotation element which is fixed by the first fixing mechanism so as to rotate in an event that it is determined in the torque determination step that the torque is equal to or smaller than the second threshold.
