ABSTRACT:
In a clutch engaging and disengaging operation at the time of a shift change, a state in which the clutch position of the clutch is at a specific value between a first clutch position at which a half clutch state finishes and a second clutch position at which the clutch is in a mechanical maximum disengaged state is maintained until completion of a gear change is detected by a gear position sensor. Therefore, even if a dog abutment state occurs between first gears with engaging projections and second gears with engaging recesses, the dog abutment can be resolved properly.
