<P>PROBLEM TO BE SOLVED: To provide a vehicular power transmission control apparatus capable of suppressing deterioration of drivability in starting an internal combustion engine by using power of an input shaft of a transmission during rotation in an EV running state in a vehicle power transmission control apparatus applied to a 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 any 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, "an OUT-Connection State" in which a power transmission path is provided between the transmission output shaft and the electric motor output shaft, and "a neutral state" in which no transmission path therebetween is provided. When the internal combustion engine is started in the EV running state where a vehicle travels only by electric motor drive torque Tm, a rotational speed Ne of the internal combustion engine is increased from zero by the power of the transmission input shaft by shifting a clutch from a shut off state to a half-engagement state. The electric motor drive torque Tm is increased by considering counter torque (-Te) in a vehicle reduction direction applied to the transmission input shaft. <P>COPYRIGHT: (C)2011,JPO&INPIT |
