ABSTRACT:
An electric-power-assist transmission and a shaft control method which allow good operability to be obtained. A main clutch is put in an engaged or disengaged state in a manner which is mechanically coupled with the rotation of a shift spindle. At normal times, the rotational direction and the rotational speed of the shift spindle rotated by a driving motor are controlled in accordance with a first control procedure. However, with the main clutch in a disengaged state, as the rotational speed of the engine exhibits a predicted change, the rotational direction and the rotational speed of the shift spindle are controlled in accordance with a second control procedure which is different from the first control procedure.
