Abstract: A transmission system is provided utilizing multiple sets of clutch friction elements, each engaged to transfer torque from a torque input, such as an engine, to different gear ratios. The sets of clutch friction elements are operated simultaneously to provide a blended, gear ratio to a drivetrain. By varying the engagement of the clutch elements, and thus the proportion of the torque transferred to the gear ratio associated with each set of friction elements, an intermediate, effective gear ratio is developed. This effective gear ratio can be increased or decreased in response to external stimuli, such as vehicle and/or engine sensors, by modifying the degree of engagement of each set of clutch friction elements, and thus the proportion of torque transferred by each set of elements to its associated gear ratio.

Abstract: A transmission, by means of inserting an electric motor between a couple of clutch shafts of twin-clutch type automatic transmission and controlling the torque and speed of the electric motor, establishing a smooth and efficient gear shifting control as well as enable to realize a creep control, idling stop starting control, R-to-D, D-to-R selecting control. 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 the friction control of the clutch is not performed, smooth gear shift work can be realized, and the same control scheme extends to creep control, idling stop starting control, R-to-D, D-to-R selecting control to be enabled, which leads to such an effect that the life is extended without the clutch being worn away, as well as the drivability can be increased remarkably.
