Abstract
After engagement of a clutch is suppressed from being started and a rotational speed of an input shaft of an automatic transmission is suppressed from being increased due to an increase in rotation resistance of the input shaft of the automatic transmission, which occurs by half-engagement of a clutch, the clutch is disengaged, and the clutch is completely engaged. In this way, the clutch is completely engaged after the rotational speed of the input shaft is suppressed from being increased. Thus, a heat generation amount of the clutch can be reduced, and furthermore, durability of the clutch can be improved by a reduction in the heat generation amount.
