Abstract
The gear shifting control device comprises a speed change operation completion detecting portion, a rotation difference judging portion for judging whether or not the absolute difference between the engine rotation speed and the input rotation speed exceeds a predetermined value and a clutch torque—operating amount correcting portion which replaces the clutch torque corresponding to the clutch actuator operating amount corresponding to the target clutch torque with a presumed clutch torque. Thus the correction accuracy for the clutch actuator operating amount can be improved by learning a speed change state by extracting a suitable state for learning.
