"textContent": "When conducting power-on shift by a clutch-to-clutch in an automatic transmission (48), friction control is unstable, and theoretically, torque transition is impossible when gear is downshifted. Also, so-called skip shift, i.e., the transmission between the transmission gears on the same clutch shaft cannot be done. Conducting active transmission by means of a motor (30) enables up-shift and/or down-shift and also a torque transit transmission, as well as, enables the skip shift, as a practical application thereof. The torque of a first input shaft is transferred to a second input shaft, contemporarily, by means of the motor (30), and during this, gears of the first input shaft are exchanged.",
