ABSTRACT:
An electric motor is inserted between clutch shafts of a twin-clutch type automatic transmission are controlled for the torque and speed of the electric motor, establishing a smooth and efficient gear shifting control as well for a creep control, idling stop starting control, and R-to-D, D-to-R selecting control being controlled. The pre-stage gear is released after the torque transfer is completed with the electric motor, and the clutch is exchanged after synchronizing the motor speed with the electric motor. As a single transmission can realize multiple functions, there is such an effect that the overall cost can be reduced relatively.
