Abstract

When a contradictory event in which raising of the engine rotation speed is detected and the inertia phase start time is early occurs (8), a learn correction is made to engagement hydraulic pressure (ON side). If the raising of the engine rotation speed cannot be canceled still after the learn correction is made, release hydraulic pressure (OFF side) is increased for correction.
