<P>PROBLEM TO BE SOLVED: To appropriately change an electric motor connection state when a shortage of regenerative torque is detected during deceleration of a vehicle by regenerative torque in a vehicular power transmission control apparatus applied to the vehicle having an internal combustion engine and an electric motor as power sources. <P>SOLUTION: The apparatus includes a changeover mechanism which changes a connection state of an electric motor output shaft to either one of "an IN-Connection State" in which a power transmission path is provided between a transmission input shaft and the electric motor output shaft, and "an OUT-Connection State" in which a power transmission path is provided between the transmission output shaft and the electric motor output shaft. When "a regenerative torque shortage state" is detected (t2) during deceleration of a vehicle by electric motor regenerative torque (-Tm), and a switched electric motor connection state provides a lager "electric motor regenerative maximum torque", the electric motor connection state is changed (t3 to t4). In addition, "a bottom of the electric motor regenerative torque" generated accompanying the change is compensated (t2 to t5) by an E/G reduction torque (-Te). <P>COPYRIGHT: (C)2011,JPO&INPIT |
