Abstract
An apparatus, applied to a vehicle having an internal combustion engine and an electric motor as power sources, comprises a changeover mechanism which is able to change 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 a changeover condition is satisfied, a period is provided in which a sum Ts of an internal-combustion-engine-side-output-torque Te and an electric-motor-side-output-torque Tm coincides with a required driving torque Tr, and an electric motor torque continues to be zero.
