PROBLEM TO BE SOLVED: To solve such problems that, when a automatic transmission perform power-on-shifting by a clutch-to-clutch operation, a friction control is unstable, and when down-shifting, to perform torque transition is in principle impossible, and a so-called skipping shift between changing shift gears on the same clutch shaft is impossible, to improve a driving performance by means of skipping shift which was conventionally impossible, to remove a twin clutch by performing only the skipping shift, and to reduce motor capacity by providing with a middle stage gear, so that a economical transmission device can be obtained. SOLUTION: An active shifting by means of a motor allows torque transition shifting for either upshifting or downshifting, and as an application, permits a skipping shift. The torque of a first input shaft moves temporarily to a second input shaft by means of the motor, during which a gear of the first input shaft is shifted. |
