PROBLEM TO BE SOLVED: To provide a learning control device of an automatic transmission capable of executing learning control to be able to prevent nt-blow even under a situation where an input torque of the automatic transmission is changed during clutch-to-clutch gear shifting. SOLUTION: When a transmission input shaft rotational number is increased during clutch-to-clutch gear shifting, it is determined whether or not an engine torque is increased at the rising timing. When the start of the increase in the transmission input shaft rotational number is not caused by the increase of the engine torque, it is determined that the increase of the transmission input shaft rotational number is the torque capacity shortage of the clutch so as to execute learning control. When the start of the increase in the transmission input shaft rotational number is caused by the increase of the engine torque, learning control is inhibited. COPYRIGHT: (C)2010,JPO&INPIT |
