Title:
自動変速機及びその制御装置
Document Type and Number:
Japanese Patent JP4199456
Kind Code:
B2
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. As a single transmission can realize multiple functions, there is such an effect that the overall cost can be reduced relatively.
